When you use the snapshots, you should be +able to maintain a local copy of libc that is no more than one day older than +the official source tree used by the libc maintainers. + +The primary purpose of providing snapshots is to widen the group of motivated +developers that would like to help test, debug, and enhance glibc, by providing +you with access to the "latest and greatest" source. This has several +advantages, and several disadvantages. + + First the advantages: + + o Once we have a large base of motivated testers using the snapshots, + this should provide good coverage across all currently supported + glibc hosts and targets. If a new bug is introduced in glibc due to + fixing another bug or ongoing development, it should become + obvious much more quickly and get fixed before the next general + net release. This should help to reduce the chances of glibc being + released to the general public with a major bug that went unnoticed + during the release cycle testing because they are machine dependent. + We hope to greatly improve glibc's stability and reliability by + involving more people and more execution environments in the + prerelease testing. + + o With access to the latest source, any diffs that you send to fix + bugs or add new features should be much easier for the glibc team + to merge into the official source base (after suitable review + of course). This encourages us to merge your changes quicker, + while they are still "fresh". + + o Once your diffs are merged, you can obtain a new copy of glibc + containing your changes almost immediately. Thus you do not + have to maintain local copies of your changes for any longer + than it takes to get them merged into the official source base. + This encourages you to send in changes quicker. + + And the disadvantages: + + o The snapshot you get will be largely untested and of unknown quality. + It may fail to configure or compile. It may have serious bugs. + You should always keep a copy of the last known working version + before updating to the current snapshot, or at least be able to + regenerate a working version if the latest snapshot is unusable + in your environment for some reason. + + If a production version of glibc has a bug and a snapshot has the fix, + and you care about stability, you should put only the fix for that + particular problem into your production version. Of course, if you + are eager to test glibc, you can use the snapshot versions in your + daily work, but users who have not been consulted about whether they + feel like testing glibc should generally have something which is at + least as bug free as the last released version. + + o Providing timely response to your questions, bug reports, and + submitted patches will require the glibc development team to allocate + time from an already thin time budget. Please try to help us make + this time as productive as possible. See the section below about + how to submit changes. + + +WHO SHOULD TRY THE SNAPSHOTS +---------------------------- + +Remember, these are snapshots not tested versions. So if you use +these versions you should be able to + + o make sure your system stays usable + + o locate and hopefully fix problems + + o to port glibc to a new target yourself + +You should not use the snapshots if + + o your system is needed in a production environment which needs + stability + + o you expect us to fix your problems since you somehow depend on them. + You must be willing to fix the problems yourself, we don't want to + see "I have problems, fix this" messages. + + +HOW TO GET THE SNAPSHOTS +------------------------ + +At the moment we provide a full snapshot weekly (every sunday), so +that users getting a snapshot for the first time, or updating after +a long period of not updating, can get the latest version in a single +operation. Along with the full snapshot, we will provide incremental +diffs on a nearly daily basis (whenever code changes). Each daily +diff will be relative to the source tree after applying all previous +daily diffs. The daily diffs are for people who have relatively low +bandwidth ftp or uucp connections. + +The files will be available via anonymous ftp from alpha.gnu.org, in +directory /gnu/libc and on linux.kernel.org in /pub/software/libs/glibc. The +directories should look something like: + + libc-970921.tar.gz + libc-970917-970922.diff.gz + libc-970922-970925.diff.gz + . + . + . + +Please note that the snapshots on alpha.gnu.org and on +linux.kernel.org are not always in sync. Patches to some files might +appear a day a diff earlier or later on alpha than on kernel. +Use always alpha or always kernel but don't mix them. + +There are sometimes additionally test releases of the add-ons available in +these directories. If a new version of an add-on is available it is normally +required for the corresponding snapshot so always pay attention for these. + +Note that we provide GNU gzip compressed files only. You can ftp gzip +from ftp.gnu.org in directory pub/gnu. + +In some cases the dates for diffs and snapshots do not match like in the +example above. The full release is for 970921 but the patch is for +970917-970922. This only means that nothing changed between 970917 and 970922 +and that you have to use this patch on top of the 970921 snapshot since the +patch is made on 970922. + +Also, as the gcc developers did with their gcc snapshot system, even though we +will make the snapshots available on a publically accessible ftp area, we ask +that recipients not widely publicise their availability. The motivation for +this request is not to hoard them, but to avoid the situation where the +general glibc user base naively attempts to use the snapshots, has trouble with +them, complains publically, and the reputation of glibc declines because of a +perception of instability or lack of quality control. + + +GLIBC TEST SUITE +---------------- + +A test suite is distributed as an integral part of the snapshots. A simple +"make check" in your build directory is sufficient to run the tests. glibc +should pass all tests and if any fails, please report it. A failure might not +originate from a bug in glibc but also from bugs in the tools, e.g. with gcc +2.7.2.x the math tests fail some of the tests because of compiler bugs. + +Note that the test suite is still in its infancy. The tests themselves only +cover a small portion of libc features, and where tests do exist for a feature +they are not exhaustive. New tests are welcome. + + +GETTING HELP, GLIBC DISCUSSIONS, etc +------------------------------------ + +People who want to help with glibc and who test out snapshots +regularly should get on the libc-alpha@sourceware.cygnus.com mailing +list by sending an email to libc-alpha-subscribe@sourceware.cygnus.com. +This list is meant (as the name suggests) for the discussion of test +releases and also reports for them. People who are on this list are +welcome to post questions of general interest. + +People who are not only willing to test the snapshots but instead +really want to help developing glibc should contact +libc-hacker-subscribe@sourceware.cygnus.com.org to be put on the developers +mailing list. This list is really only meant for developers. No +questions about installation problems or other simple topics are +wanted nor will they be answered. + +Do *not* send any questions about the snapshots or patches specific to the +snapshots to bug-glibc@gnu.org. Nobody there will have any idea what +you are talking about and it will just cause confusion. + + +BUG REPORTS +----------- + +Send bug reports directly to Ulrich Drepper . Please +do *not* use the glibcbug script for reporting bugs in the snapshots. +glibcbug should only be used for problems with the official released versions. +We don't like bug reports in the bug database because otherwise the impression +of instability or lack of quality control of glibc as a whole might manifest +in people's mind. + +Note that since no testing is done on the snapshots, and snapshots may even be +made when glibc is in an inconsistent state, it may not be unusual for an +occasional snapshot to have a very obvious bug, such as failure to compile on +*any* machine. It is likely that such bugs will be fixed by the next +snapshot, so it really isn't necessary to report them unless they persist for +a couple of days. + +Missing files should always be reported, since they usually mean there is a +problem with the snapshot-generating process and we won't know about them +unless someone tells us. + +Bugs which are non-obvious, such as failure to compile on only a specific +machine, a new machine dependent or obscure bug (particularly one not detected +by the testsuite), etc should be reported when you discover them, or have a +suggested patch to fix them. + + +FORMAT FOR PATCHES +------------------ + +If you have a fix for a bug, or an enhancement to submit, send your patch to +Ulrich Drepper . Here are some simple guidelines for +submitting patches: + + o Use "unified diffs" for patches. A typical command for generating + context diffs is "diff -ru glibc-old glibc-patched". + + o Use the "minimalist approach" for patches. That is, each patch + should address only one particular bug, new feature, etc. Do not + save up many unrelated changes and submit them all in one big + patch, since in general, the larger the patch the more difficult + it is for us to decide if the patch is either correct or + desirable. And if we find something about the patch that needs + to be corrected before it can be installed, we would have to reject + the entire patch, which might contain changes which otherwise would + be accepted if submitted separately. + + o Submit a sample ChangeLog entry with your patch. See the existing + glibc ChangeLog for examples of what a ChangeLog entry should look + like. The emacs command ^X4A will create a ChangeLog entry header + for you. + + +BUILDING SNAPSHOTS +------------------ + +The `best' way to build glibc is to use an extra directory, e.g.: +tar xzf libc-970921.tar.gz +mkdir build-glibc +cd build-glibc +../libc-970921/configure ... + +In this way you can easily clean up (since `make clean' doesn't work at +the moment) and rebuild glibc. + + +NECESSARY TOOLS +--------------- + +For the recommended versions of gcc, binutils, make, texinfo, gettext, +autoconf and other tools which might be especially needed when using patches, +please read the file INSTALL. + + +HOW CAN YOU HELP +---------------- + +It helps already a lot if you just install glibc on your system and try to +solve any problems. You might want to look at the file `PROJECTS' and help +with one of those projects, fix some bugs (see `BUGS' or the bug database), +port to an unsupported platform, ... + + +FURTHER DOCUMENTATION +--------------------- + +A lot of questions are answered in the FAQ. The files `INSTALL', `README' and +`NOTES' contain the most important documentation. Furthermore glibc has its +own 700+ pages info documentation, ... + + + +And finally a word of caution: The libc is one of the most fundamental parts +of your system - and these snapshots are untested and come without any +guarantee or warranty. You might be lucky and everything works or you might +crash your system. If you install a glibc snapshot as primary library, you +should have a backup somewhere. + +On many systems it is also a problem to replace the libc while the system is +running. In the worst case on broken OSes some systems crash. On better +systems you can move the old libc aside but removing it will cause problems +since there are still processes using this libc image and so you might have to +check the filesystem to get rid of the libc data. One good alternative (which +is also safer) is to use a chroot'ed environment. + +Thanks for your help and support. + +Thanks to Fred Fish from Cygnus for the original version of this text +(for GDB). + + +Ulrich Drepper diff -u -udbrN glibc-2.3.2/README.template glibc-2.3.2-200304020432/README.template --- glibc-2.3.2/README.template Thu Jan 1 01:00:00 1970 +++ glibc-2.3.2-200304020432/README.template Wed Oct 2 23:16:42 2002 @@ -0,0 +1,87 @@ +This directory contains the version VERSION release of the GNU C Library. +Many bugs have been fixed since the last release. +Some bugs surely remain. + +As of this release, the GNU C library is known to run on the following +configurations: + + *-*-gnu GNU Hurd + i[3456]86-*-linux-gnu Linux-2.x on Intel + m68k-*-linux-gnu Linux-2.x on Motorola 680x0 + alpha*-*-linux-gnu Linux-2.x on DEC Alpha + powerpc-*-linux-gnu Linux and MkLinux on PowerPC systems + powerpc64-*-linux-gnu Linux-2.4.19+ on 64-bit PowerPC systems + sparc-*-linux-gnu Linux-2.x on SPARC + sparc64-*-linux-gnu Linux-2.x on UltraSPARC 64-bit + arm-*-none ARM standalone systems + arm-*-linux Linux-2.x on ARM + arm-*-linuxaout Linux-2.x on ARM using a.out binaries + mips*-*-linux-gnu Linux-2.x on MIPS + ia64-*-linux-gnu Linux-2.x on ia64 + s390-*-linux-gnu Linux-2.x on IBM S/390 + s390x-*-linux-gnu Linux-2.4+ on IBM S/390 64-bit + sh-*-linux-gnu Linux-2.x on Super Hitachi + cris-*-linux-gnu Linux-2.4+ on CRIS + x86-64-*-linux-gnu Linux-2.4+ on x86-64 + +Former releases of this library (version 1.09.1 and perhaps earlier +versions) used to run on the following configurations: + + alpha-dec-osf1 + i[3456]86-*-bsd4.3 + i[3456]86-*-isc2.2 + i[3456]86-*-isc3 + i[3456]86-*-sco3.2 + i[3456]86-*-sco3.2v4 + i[3456]86-*-sysv + i[3456]86-*-sysv4 + i[3456]86-force_cpu386-none + i[3456]86-sequent-bsd + i960-nindy960-none + m68k-hp-bsd4.3 + m68k-mvme135-none + m68k-mvme136-none + m68k-sony-newsos3 + m68k-sony-newsos4 + m68k-sun-sunos4 + mips-dec-ultrix4 + mips-sgi-irix4 + sparc-sun-solaris2 + sparc-sun-sunos4 + +Since no one has volunteered to test and fix the above configurations, +these are not supported at the moment.

The reason that -these original functions are not described first is that they are almost -entirely useless. - - The problem is that all the conversion functions described in the -original ISO C90 use a local state. Using a local state implies that -multiple conversions at the same time (not only when using threads) -cannot be done, and that you cannot first convert single characters and -then strings since you cannot tell the conversion functions which state -to use. - - These original functions are therefore usable only in a very limited -set of situations. One must complete converting the entire string -before starting a new one, and each string/text must be converted with -the same function (there is no problem with the library itself; it is -guaranteed that no library function changes the state of any of these -functions). *For the above reasons it is highly requested that the -functions described in the previous section be used in place of -non-reentrant conversion functions.* - -* Menu: - -* Non-reentrant Character Conversion:: Non-reentrant Conversion of Single - Characters. -* Non-reentrant String Conversion:: Non-reentrant Conversion of Strings. -* Shift State:: States in Non-reentrant Functions. - - -File: libc.info, Node: Non-reentrant Character Conversion, Next: Non-reentrant String Conversion, Up: Non-reentrant Conversion - -Non-reentrant Conversion of Single Characters ---------------------------------------------- - - - Function: int mbtowc (wchar_t *restrict RESULT, const char *restrict - STRING, size_t SIZE) - The `mbtowc' ("multibyte to wide character") function when called - with non-null STRING converts the first multibyte character - beginning at STRING to its corresponding wide character code. It - stores the result in `*RESULT'. - - `mbtowc' never examines more than SIZE bytes. (The idea is to - supply for SIZE the number of bytes of data you have in hand.) - - `mbtowc' with non-null STRING distinguishes three possibilities: - the first SIZE bytes at STRING start with valid multibyte - characters, they start with an invalid byte sequence or just part - of a character, or STRING points to an empty string (a null - character). - - For a valid multibyte character, `mbtowc' converts it to a wide - character and stores that in `*RESULT', and returns the number of - bytes in that character (always at least 1 and never more than - SIZE). - - For an invalid byte sequence, `mbtowc' returns -1. For an empty - string, it returns 0, also storing `'\0'' in `*RESULT'. - - If the multibyte character code uses shift characters, then - `mbtowc' maintains and updates a shift state as it scans. If you - call `mbtowc' with a null pointer for STRING, that initializes the - shift state to its standard initial value.

At - most `MB_CUR_MAX' characters are stored. - - `wctomb' with non-null STRING distinguishes three possibilities - for WCHAR: a valid wide character code (one that can be translated - to a multibyte character), an invalid code, and `L'\0''. - - Given a valid code, `wctomb' converts it to a multibyte character, - storing the bytes starting at STRING. Then it returns the number - of bytes in that character (always at least 1 and never more than - `MB_CUR_MAX'). - - If WCHAR is an invalid wide character code, `wctomb' returns -1. - If WCHAR is `L'\0'', it returns `0', also storing `'\0'' in - `*STRING'. - - If the multibyte character code uses shift characters, then - `wctomb' maintains and updates a shift state as it scans. If you - call `wctomb' with a null pointer for STRING, that initializes the - shift state to its standard initial value. It also returns - nonzero if the multibyte character code in use actually has a - shift state. *Note Shift State::. - - Calling this function with a WCHAR argument of zero when STRING is - not null has the side-effect of reinitializing the stored shift - state _as well as_ storing the multibyte character `'\0'' and - returning 0. - - Similar to `mbrlen' there is also a non-reentrant function that -computes the length of a multibyte character. It can be defined in -terms of `mbtowc'. - - - Function: int mblen (const char *STRING, size_t SIZE) - The `mblen' function with a non-null STRING argument returns the - number of bytes that make up the multibyte character beginning at - STRING, never examining more than SIZE bytes. (The idea is to - supply for SIZE the number of bytes of data you have in hand.) - - The return value of `mblen' distinguishes three possibilities: the - first SIZE bytes at STRING start with valid multibyte characters, - they start with an invalid byte sequence or just part of a - character, or STRING points to an empty string (a null character). - - For a valid multibyte character, `mblen' returns the number of - bytes in that character (always at least `1' and never more than - SIZE). For an invalid byte sequence, `mblen' returns -1. For an - empty string, it returns 0. - - If the multibyte character code uses shift characters, then `mblen' - maintains and updates a shift state as it scans.

Otherwise, it returns the number - of wide characters stored in the array WSTRING. This number does - not include the terminating null character, which is present if the - number is less than SIZE. - - Here is an example showing how to convert a string of multibyte - characters, allocating enough space for the result. - - wchar_t * - mbstowcs_alloc (const char *string) - { - size_t size = strlen (string) + 1; - wchar_t *buf = xmalloc (size * sizeof (wchar_t)); - - size = mbstowcs (buf, string, size); - if (size == (size_t) -1) - return NULL; - buf = xrealloc (buf, (size + 1) * sizeof (wchar_t)); - return buf; - } - - - - Function: size_t wcstombs (char *STRING, const wchar_t *WSTRING, - size_t SIZE) - The `wcstombs' ("wide character string to multibyte string") - function converts the null-terminated wide character array WSTRING - into a string containing multibyte characters, storing not more - than SIZE bytes starting at STRING, followed by a terminating null - character if there is room. The conversion of characters begins in - the initial shift state. - - The terminating null character counts towards the size, so if SIZE - is less than or equal to the number of bytes needed in WSTRING, no - terminating null character is stored. - - If a code that does not correspond to a valid multibyte character - is found, the `wcstombs' function returns a value of -1. - Otherwise, the return value is the number of bytes stored in the - array STRING. This number does not include the terminating null - character, which is present if the number is less than SIZE. - - -File: libc.info, Node: Shift State, Prev: Non-reentrant String Conversion, Up: Non-reentrant Conversion - -States in Non-reentrant Functions ---------------------------------- - - In some multibyte character codes, the _meaning_ of any particular -byte sequence is not fixed; it depends on what other sequences have come -earlier in the same string. Typically there are just a few sequences -that can change the meaning of other sequences; these few are called -"shift sequences" and we say that they set the "shift state" for other -sequences that follow. - - To illustrate shift state and shift sequences, suppose we decide that -the sequence `0200' (just one byte) enters Japanese mode, in which -pairs of bytes in the range from `0240' to `0377' are single -characters, while `0201' enters Latin-1 mode, in which single bytes in -the range from `0240' to `0377' are characters, and interpreted -according to the ISO Latin-1 character set. This is a multibyte code -that has two alternative shift states ("Japanese mode" and "Latin-1 -mode"), and two shift sequences that specify particular shift states. - - When the multibyte character code in use has shift states, then -`mblen', `mbtowc', and `wctomb' must maintain and update the current -shift state as they scan the string. To make this work properly, you -must follow these rules: - - * Before starting to scan a string, call the function with a null - pointer for the multibyte character address--for example, `mblen - (NULL, 0)'. This initializes the shift state to its standard - initial value. - - * Scan the string one character at a time, in order. Do not "back - up" and rescan characters already scanned, and do not intersperse - the processing of different strings. - - Here is an example of using `mblen' following these rules: - - void - scan_string (char *s) - { - int length = strlen (s); - - /* Initialize shift state. */ - mblen (NULL, 0); - - while (1) - { - int thischar = mblen (s, length); - /* Deal with end of string and invalid characters. */ - if (thischar == 0) - break; - if (thischar == -1) - { - error ("invalid multibyte character"); - break; - } - /* Advance past this character. */ - s += thischar; - length -= thischar; - } - } - - The functions `mblen', `mbtowc' and `wctomb' are not reentrant when -using a multibyte code that uses a shift state. However, no other -library functions call these functions, so you don't have to worry that -the shift state will be changed mysteriously. - - -File: libc.info, Node: Generic Charset Conversion, Prev: Non-reentrant Conversion, Up: Character Set Handling - -Generic Charset Conversion -========================== - - The conversion functions mentioned so far in this chapter all had in -common that they operate on character sets that are not directly -specified by the functions. The multibyte encoding used is specified by -the currently selected locale for the `LC_CTYPE' category. The wide -character set is fixed by the implementation (in the case of GNU C -library it is always UCS-4 encoded ISO 10646. - - This has of course several problems when it comes to general -character conversion: - - * For every conversion where neither the source nor the destination - character set is the character set of the locale for the `LC_CTYPE' - category, one has to change the `LC_CTYPE' locale using - `setlocale'. - - Changing the `LC_TYPE' locale introduces major problems for the - rest of the programs since several more functions (e.g., the - character classification functions, *note Classification of - Characters::) use the `LC_CTYPE' category. - - * Parallel conversions to and from different character sets are not - possible since the `LC_CTYPE' selection is global and shared by all - threads. - - * If neither the source nor the destination character set is the - character set used for `wchar_t' representation, there is at least - a two-step process necessary to convert a text using the functions - above. One would have to select the source character set as the - multibyte encoding, convert the text into a `wchar_t' text, select - the destination character set as the multibyte encoding, and - convert the wide character text to the multibyte (= destination) - character set. - - Even if this is possible (which is not guaranteed) it is a very - tiring work. Plus it suffers from the other two raised points - even more due to the steady changing of the locale. - - The XPG2 standard defines a completely new set of functions, which -has none of these limitations. They are not at all coupled to the -selected locales, and they have no constraints on the character sets -selected for source and destination. Only the set of available -conversions limits them. The standard does not specify that any -conversion at all must be available. Such availability is a measure of -the quality of the implementation. - - In the following text first the interface to `iconv' and then the -conversion function, will be described. Comparisons with other -implementations will show what obstacles stand in the way of portable -applications. Finally, the implementation is described in so far as -might interest the advanced user who wants to extend conversion -capabilities. - -* Menu: - -* Generic Conversion Interface:: Generic Character Set Conversion Interface. -* iconv Examples:: A complete `iconv' example. -* Other iconv Implementations:: Some Details about other `iconv' - Implementations. -* glibc iconv Implementation:: The `iconv' Implementation in the GNU C - library. - - -File: libc.info, Node: Generic Conversion Interface, Next: iconv Examples, Up: Generic Charset Conversion - -Generic Character Set Conversion Interface ------------------------------------------- - - This set of functions follows the traditional cycle of using a -resource: open-use-close. The interface consists of three functions, -each of which implements one step. - - Before the interfaces are described it is necessary to introduce a -data type. Just like other open-use-close interfaces the functions -introduced here work using handles and the `iconv.h' header defines a -special type for the handles used. - - - Data Type: iconv_t - This data type is an abstract type defined in `iconv.h'. The user - must not assume anything about the definition of this type; it - must be completely opaque. - - Objects of this type can get assigned handles for the conversions - using the `iconv' functions. The objects themselves need not be - freed, but the conversions for which the handles stand for have to. - -The first step is the function to create a handle. - - - Function: iconv_t iconv_open (const char *TOCODE, const char - *FROMCODE) - The `iconv_open' function has to be used before starting a - conversion. The two parameters this function takes determine the - source and destination character set for the conversion, and if the - implementation has the possibility to perform such a conversion, - the function returns a handle. - - If the wanted conversion is not available, the `iconv_open' - function returns `(iconv_t) -1'. In this case the global variable - `errno' can have the following values: - - `EMFILE' - The process already has `OPEN_MAX' file descriptors open. - - `ENFILE' - The system limit of open file is reached. - - `ENOMEM' - Not enough memory to carry out the operation. - - `EINVAL' - The conversion from FROMCODE to TOCODE is not supported. - - It is not possible to use the same descriptor in different threads - to perform independent conversions. The data structures associated - with the descriptor include information about the conversion state. - This must not be messed up by using it in different conversions. - - An `iconv' descriptor is like a file descriptor as for every use a - new descriptor must be created. The descriptor does not stand for - all of the conversions from FROMSET to TOSET. - - The GNU C library implementation of `iconv_open' has one - significant extension to other implementations. To ease the - extension of the set of available conversions, the implementation - allows storing the necessary files with data and code in an - arbitrary number of directories. How this extension must be - written will be explained below (*note glibc iconv - Implementation::). Here it is only important to say that all - directories mentioned in the `GCONV_PATH' environment variable are - considered only if they contain a file `gconv-modules'. These - directories need not necessarily be created by the system - administrator. In fact, this extension is introduced to help users - writing and using their own, new conversions. Of course, this - does not work for security reasons in SUID binaries; in this case - only the system directory is considered and this normally is - `PREFIX/lib/gconv'. The `GCONV_PATH' environment variable is - examined exactly once at the first call of the `iconv_open' - function. Later modifications of the variable have no effect. - - The `iconv_open' function was introduced early in the X/Open - Portability Guide, version 2. It is supported by all commercial - Unices as it is required for the Unix branding. However, the - quality and completeness of the implementation varies widely. The - `iconv_open' function is declared in `iconv.h'. - - The `iconv' implementation can associate large data structure with -the handle returned by `iconv_open'. Therefore, it is crucial to free -all the resources once all conversions are carried out and the -conversion is not needed anymore. - - - Function: int iconv_close (iconv_t CD) - The `iconv_close' function frees all resources associated with the - handle CD, which must have been returned by a successful call to - the `iconv_open' function. - - If the function call was successful the return value is 0. - Otherwise it is -1 and `errno' is set appropriately. Defined - error are: - - `EBADF' - The conversion descriptor is invalid. - - The `iconv_close' function was introduced together with the rest - of the `iconv' functions in XPG2 and is declared in `iconv.h'. - - The standard defines only one actual conversion function. This has, -therefore, the most general interface: it allows conversion from one -buffer to another. Conversion from a file to a buffer, vice versa, or -even file to file can be implemented on top of it. - - - Function: size_t iconv (iconv_t CD, char **INBUF, size_t - *INBYTESLEFT, char **OUTBUF, size_t *OUTBYTESLEFT) - The `iconv' function converts the text in the input buffer - according to the rules associated with the descriptor CD and - stores the result in the output buffer. It is possible to call the - function for the same text several times in a row since for - stateful character sets the necessary state information is kept in - the data structures associated with the descriptor. - - The input buffer is specified by `*INBUF' and it contains - `*INBYTESLEFT' bytes. The extra indirection is necessary for - communicating the used input back to the caller (see below). It is - important to note that the buffer pointer is of type `char' and the - length is measured in bytes even if the input text is encoded in - wide characters. - - The output buffer is specified in a similar way. `*OUTBUF' points - to the beginning of the buffer with at least `*OUTBYTESLEFT' bytes - room for the result. The buffer pointer again is of type `char' - and the length is measured in bytes. If OUTBUF or `*OUTBUF' is a - null pointer, the conversion is performed but no output is - available. - - If INBUF is a null pointer, the `iconv' function performs the - necessary action to put the state of the conversion into the - initial state. This is obviously a no-op for non-stateful - encodings, but if the encoding has a state, such a function call - might put some byte sequences in the output buffer, which perform - the necessary state changes. The next call with INBUF not being a - null pointer then simply goes on from the initial state. It is - important that the programmer never makes any assumption as to - whether the conversion has to deal with states. Even if the input - and output character sets are not stateful, the implementation - might still have to keep states. This is due to the - implementation chosen for the GNU C library as it is described - below. Therefore an `iconv' call to reset the state should always - be performed if some protocol requires this for the output text. - - The conversion stops for one of three reasons. The first is that - all characters from the input buffer are converted. This actually - can mean two things: either all bytes from the input buffer are - consumed or there are some bytes at the end of the buffer that - possibly can form a complete character but the input is - incomplete. The second reason for a stop is that the output - buffer is full. And the third reason is that the input contains - invalid characters. - - In all of these cases the buffer pointers after the last successful - conversion, for input and output buffer, are stored in INBUF and - OUTBUF, and the available room in each buffer is stored in - INBYTESLEFT and OUTBYTESLEFT. - - Since the character sets selected in the `iconv_open' call can be - almost arbitrary, there can be situations where the input buffer - contains valid characters, which have no identical representation - in the output character set. The behavior in this situation is - undefined. The _current_ behavior of the GNU C library in this - situation is to return with an error immediately. This certainly - is not the most desirable solution; therefore, future versions - will provide better ones, but they are not yet finished. - - If all input from the input buffer is successfully converted and - stored in the output buffer, the function returns the number of - non-reversible conversions performed. In all other cases the - return value is `(size_t) -1' and `errno' is set appropriately. - In such cases the value pointed to by INBYTESLEFT is nonzero. - - `EILSEQ' - The conversion stopped because of an invalid byte sequence in - the input. After the call, `*INBUF' points at the first byte - of the invalid byte sequence. - - `E2BIG' - The conversion stopped because it ran out of space in the - output buffer. - - `EINVAL' - The conversion stopped because of an incomplete byte sequence - at the end of the input buffer. - - `EBADF' - The CD argument is invalid. - - The `iconv' function was introduced in the XPG2 standard and is - declared in the `iconv.h' header. - - The definition of the `iconv' function is quite good overall. It -provides quite flexible functionality. The only problems lie in the -boundary cases, which are incomplete byte sequences at the end of the -input buffer and invalid input. A third problem, which is not really a -design problem, is the way conversions are selected. The standard does -not say anything about the legitimate names, a minimal set of available -conversions. We will see how this negatively impacts other -implementations, as demonstrated below. - - -File: libc.info, Node: iconv Examples, Next: Other iconv Implementations, Prev: Generic Conversion Interface, Up: Generic Charset Conversion - -A complete `iconv' example --------------------------- - - The example below features a solution for a common problem. Given -that one knows the internal encoding used by the system for `wchar_t' -strings, one often is in the position to read text from a file and store -it in wide character buffers. One can do this using `mbsrtowcs', but -then we run into the problems discussed above. - - int - file2wcs (int fd, const char *charset, wchar_t *outbuf, size_t avail) - { - char inbuf[BUFSIZ]; - size_t insize = 0; - char *wrptr = (char *) outbuf; - int result = 0; - iconv_t cd; - - cd = iconv_open ("WCHAR_T", charset); - if (cd == (iconv_t) -1) - { - /* Something went wrong. */ - if (errno == EINVAL) - error (0, 0, "conversion from '%s' to wchar_t not available", - charset); - else - perror ("iconv_open"); - - /* Terminate the output string. */ - *outbuf = L'\0'; - - return -1; - } - - while (avail > 0) - { - size_t nread; - size_t nconv; - char *inptr = inbuf; - - /* Read more input. */ - nread = read (fd, inbuf + insize, sizeof (inbuf) - insize); - if (nread == 0) - { - /* When we come here the file is completely read. - This still could mean there are some unused - characters in the `inbuf'. Put them back. */ - if (lseek (fd, -insize, SEEK_CUR) == -1) - result = -1; - - /* Now write out the byte sequence to get into the - initial state if this is necessary. */ - iconv (cd, NULL, NULL, &wrptr, &avail); - - break; - } - insize += nread; - - /* Do the conversion. */ - nconv = iconv (cd, &inptr, &insize, &wrptr, &avail); - if (nconv == (size_t) -1) - { - /* Not everything went right. It might only be - an unfinished byte sequence at the end of the - buffer. Or it is a real problem. */ - if (errno == EINVAL) - /* This is harmless. Simply move the unused - bytes to the beginning of the buffer so that - they can be used in the next round. */ - memmove (inbuf, inptr, insize); - else - { - /* It is a real problem. Maybe we ran out of - space in the output buffer or we have invalid - input. In any case back the file pointer to - the position of the last processed byte. */ - lseek (fd, -insize, SEEK_CUR); - result = -1; - break; - } - } - } - - /* Terminate the output string. */ - if (avail >= sizeof (wchar_t)) - *((wchar_t *) wrptr) = L'\0'; - - if (iconv_close (cd) != 0) - perror ("iconv_close"); - - return (wchar_t *) wrptr - outbuf; - } - - This example shows the most important aspects of using the `iconv' -functions. It shows how successive calls to `iconv' can be used to -convert large amounts of text. The user does not have to care about -stateful encodings as the functions take care of everything. - - An interesting point is the case where `iconv' returns an error and -`errno' is set to `EINVAL'. This is not really an error in the -transformation. It can happen whenever the input character set contains -byte sequences of more than one byte for some character and texts are -not processed in one piece. In this case there is a chance that a -multibyte sequence is cut. The caller can then simply read the -remainder of the takes and feed the offending bytes together with new -character from the input to `iconv' and continue the work. The -internal state kept in the descriptor is _not_ unspecified after such -an event as is the case with the conversion functions from the ISO C -standard. - - The example also shows the problem of using wide character strings -with `iconv'. As explained in the description of the `iconv' function -above, the function always takes a pointer to a `char' array and the -available space is measured in bytes. In the example, the output -buffer is a wide character buffer; therefore, we use a local variable -WRPTR of type `char *', which is used in the `iconv' calls. - - This looks rather innocent but can lead to problems on platforms that -have tight restriction on alignment. Therefore the caller of `iconv' -has to make sure that the pointers passed are suitable for access of -characters from the appropriate character set. Since, in the above -case, the input parameter to the function is a `wchar_t' pointer, this -is the case (unless the user violates alignment when computing the -parameter). But in other situations, especially when writing generic -functions where one does not know what type of character set one uses -and, therefore, treats text as a sequence of bytes, it might become -tricky. - - -File: libc.info, Node: Other iconv Implementations, Next: glibc iconv Implementation, Prev: iconv Examples, Up: Generic Charset Conversion - -Some Details about other `iconv' Implementations ------------------------------------------------- - - This is not really the place to discuss the `iconv' implementation -of other systems but it is necessary to know a bit about them to write -portable programs. The above mentioned problems with the specification -of the `iconv' functions can lead to portability issues. - - The first thing to notice is that, due to the large number of -character sets in use, it is certainly not practical to encode the -conversions directly in the C library. Therefore, the conversion -information must come from files outside the C library. This is -usually done in one or both of the following ways: - - * The C library contains a set of generic conversion functions that - can read the needed conversion tables and other information from - data files. These files get loaded when necessary. - - This solution is problematic as it requires a great deal of effort - to apply to all character sets (potentially an infinite set). The - differences in the structure of the different character sets is so - large that many different variants of the table-processing - functions must be developed. In addition, the generic nature of - these functions make them slower than specifically implemented - functions. - - * The C library only contains a framework that can dynamically load - object files and execute the conversion functions contained - therein. - - This solution provides much more flexibility. The C library itself - contains only very little code and therefore reduces the general - memory footprint. Also, with a documented interface between the C - library and the loadable modules it is possible for third parties - to extend the set of available conversion modules. A drawback of - this solution is that dynamic loading must be available. - - Some implementations in commercial Unices implement a mixture of -these possibilities; the majority implement only the second solution. -Using loadable modules moves the code out of the library itself and -keeps the door open for extensions and improvements, but this design is -also limiting on some platforms since not many platforms support dynamic -loading in statically linked programs. On platforms without this -capability it is therefore not possible to use this interface in -statically linked programs. The GNU C library has, on ELF platforms, no -problems with dynamic loading in these situations; therefore, this -point is moot. The danger is that one gets acquainted with this -situation and forgets about the restrictions on other systems. - - A second thing to know about other `iconv' implementations is that -the number of available conversions is often very limited. Some -implementations provide, in the standard release (not special -international or developer releases), at most 100 to 200 conversion -possibilities. This does not mean 200 different character sets are -supported; for example, conversions from one character set to a set of -10 others might count as 10 conversions. Together with the other -direction this makes 20 conversion possibilities used up by one -character set. One can imagine the thin coverage these platform -provide. Some Unix vendors even provide only a handful of conversions, -which renders them useless for almost all uses. - - This directly leads to a third and probably the most problematic -point. The way the `iconv' conversion functions are implemented on all -known Unix systems and the availability of the conversion functions from -character set A to B and the conversion from B to C does _not_ imply -that the conversion from A to C is available. - - This might not seem unreasonable and problematic at first, but it is -a quite big problem as one will notice shortly after hitting it. To -show the problem we assume to write a program that has to convert from -A to C. A call like - - cd = iconv_open ("C", "A"); - -fails according to the assumption above. But what does the program do -now? The conversion is necessary; therefore, simply giving up is not -an option. - - This is a nuisance. The `iconv' function should take care of this. -But how should the program proceed from here on? If it tries to convert -to character set B, first the two `iconv_open' calls - - cd1 = iconv_open ("B", "A"); - -and - - cd2 = iconv_open ("C", "B"); - -will succeed, but how to find B? - - Unfortunately, the answer is: there is no general solution. On some -systems guessing might help. On those systems most character sets can -convert to and from UTF-8 encoded ISO 10646 or Unicode text. Beside -this only some very system-specific methods can help. Since the -conversion functions come from loadable modules and these modules must -be stored somewhere in the filesystem, one _could_ try to find them and -determine from the available file which conversions are available and -whether there is an indirect route from A to C. - - This example shows one of the design errors of `iconv' mentioned -above. It should at least be possible to determine the list of -available conversion programmatically so that if `iconv_open' says -there is no such conversion, one could make sure this also is true for -indirect routes. - diff -u -udbrN glibc-2.3.2/manual/libc.info-11 glibc-2.3.2-200304020432/manual/libc.info-11 --- glibc-2.3.2/manual/libc.info-11 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-11 Thu Jan 1 01:00:00 1970 @@ -1,1041 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

What -follows is a step-by-step analysis of the points raised above. The -evaluation is based on the current state of the development (as of -January 1999). The development of the `iconv' functions is not -complete, but basic functionality has solidified. - - The GNU C library's `iconv' implementation uses shared loadable -modules to implement the conversions. A very small number of -conversions are built into the library itself but these are only rather -trivial conversions. - - All the benefits of loadable modules are available in the GNU C -library implementation. This is especially appealing since the -interface is well documented (see below), and it, therefore, is easy to -write new conversion modules. The drawback of using loadable objects -is not a problem in the GNU C library, at least on ELF systems. Since -the library is able to load shared objects even in statically linked -binaries, static linking need not be forbidden in case one wants to use -`iconv'. - - The second mentioned problem is the number of supported conversions. -Currently, the GNU C library supports more than 150 character sets. The -way the implementation is designed the number of supported conversions -is greater than 22350 (150 times 149). If any conversion from or to a -character set is missing, it can be added easily. - - Particularly impressive as it may be, this high number is due to the -fact that the GNU C library implementation of `iconv' does not have the -third problem mentioned above (i.e., whenever there is a conversion -from a character set A to B and from B to C it is always possible to -convert from A to C directly). If the `iconv_open' returns an error -and sets `errno' to `EINVAL', there is no known way, directly or -indirectly, to perform the wanted conversion. - - Triangulation is achieved by providing for each character set a -conversion from and to UCS-4 encoded ISO 10646. Using ISO 10646 as an -intermediate representation it is possible to "triangulate" (i.e., -convert with an intermediate representation). - - There is no inherent requirement to provide a conversion to -ISO 10646 for a new character set, and it is also possible to provide -other conversions where neither source nor destination character set is -ISO 10646. The existing set of conversions is simply meant to cover all -conversions that might be of interest. - - All currently available conversions use the triangulation method -above, making conversion run unnecessarily slow. If, for example, -somebody often needs the conversion from ISO-2022-JP to EUC-JP, a -quicker solution would involve direct conversion between the two -character sets, skipping the input to ISO 10646 first. The two -character sets of interest are much more similar to each other than to -ISO 10646. - - In such a situation one easily can write a new conversion and -provide it as a better alternative. The GNU C library `iconv' -implementation would automatically use the module implementing the -conversion if it is specified to be more efficient. - -Format of `gconv-modules' files -............................... - - All information about the available conversions comes from a file -named `gconv-modules', which can be found in any of the directories -along the `GCONV_PATH'. The `gconv-modules' files are line-oriented -text files, where each of the lines has one of the following formats: - - * If the first non-whitespace character is a `#' the line contains - only comments and is ignored. - - * Lines starting with `alias' define an alias name for a character - set. Two more words are expected on the line. The first word - defines the alias name, and the second defines the original name - of the character set. The effect is that it is possible to use - the alias name in the FROMSET or TOSET parameters of `iconv_open' - and achieve the same result as when using the real character set - name. - - This is quite important as a character set has often many different - names. There is normally an official name but this need not - correspond to the most popular name. Beside this many character - sets have special names that are somehow constructed. For - example, all character sets specified by the ISO have an alias of - the form `ISO-IR-NNN' where NNN is the registration number. This - allows programs that know about the registration number to - construct character set names and use them in `iconv_open' calls. - More on the available names and aliases follows below. - - * Lines starting with `module' introduce an available conversion - module. These lines must contain three or four more words. - - The first word specifies the source character set, the second word - the destination character set of conversion implemented in this - module, and the third word is the name of the loadable module. - The filename is constructed by appending the usual shared object - suffix (normally `.so') and this file is then supposed to be found - in the same directory the `gconv-modules' file is in. The last - word on the line, which is optional, is a numeric value - representing the cost of the conversion. If this word is missing, - a cost of 1 is assumed. The numeric value itself does not matter - that much; what counts are the relative values of the sums of - costs for all possible conversion paths. Below is a more precise - description of the use of the cost value. - - Returning to the example above where one has written a module to -directly convert from ISO-2022-JP to EUC-JP and back. All that has to -be done is to put the new module, let its name be ISO2022JP-EUCJP.so, -in a directory and add a file `gconv-modules' with the following -content in the same directory: - - module ISO-2022-JP// EUC-JP// ISO2022JP-EUCJP 1 - module EUC-JP// ISO-2022-JP// ISO2022JP-EUCJP 1 - - To see why this is sufficient, it is necessary to understand how the -conversion used by `iconv' (and described in the descriptor) is -selected. The approach to this problem is quite simple. - - At the first call of the `iconv_open' function the program reads all -available `gconv-modules' files and builds up two tables: one -containing all the known aliases and another that contains the -information about the conversions and which shared object implements -them. - -Finding the conversion path in `iconv' -...................................... - - The set of available conversions form a directed graph with weighted -edges. The weights on the edges are the costs specified in the -`gconv-modules' files. The `iconv_open' function uses an algorithm -suitable for search for the best path in such a graph and so constructs -a list of conversions that must be performed in succession to get the -transformation from the source to the destination character set. - - Explaining why the above `gconv-modules' files allows the `iconv' -implementation to resolve the specific ISO-2022-JP to EUC-JP conversion -module instead of the conversion coming with the library itself is -straightforward. Since the latter conversion takes two steps (from -ISO-2022-JP to ISO 10646 and then from ISO 10646 to EUC-JP), the cost -is 1+1 = 2. The above `gconv-modules' file, however, specifies that -the new conversion modules can perform this conversion with only the -cost of 1. - - A mysterious item about the `gconv-modules' file above (and also the -file coming with the GNU C library) are the names of the character sets -specified in the `module' lines. Why do almost all the names end in -`//'? And this is not all: the names can actually be regular -expressions. At this point in time this mystery should not be -revealed, unless you have the relevant spell-casting materials: ashes -from an original DOS 6.2 boot disk burnt in effigy, a crucifix blessed -by St. Emacs, assorted herbal roots from Central America, sand from -Cebu, etc. Sorry! *The part of the implementation where this is used -is not yet finished. For now please simply follow the existing -examples. It'll become clearer once it is. -drepper* - - A last remark about the `gconv-modules' is about the names not -ending with `//'. A character set named `INTERNAL' is often mentioned. -From the discussion above and the chosen name it should have become -clear that this is the name for the representation used in the -intermediate step of the triangulation. We have said that this is UCS-4 -but actually that is not quite right. The UCS-4 specification also -includes the specification of the byte ordering used. Since a UCS-4 -value consists of four bytes, a stored value is effected by byte -ordering. The internal representation is _not_ the same as UCS-4 in -case the byte ordering of the processor (or at least the running -process) is not the same as the one required for UCS-4. This is done -for performance reasons as one does not want to perform unnecessary -byte-swapping operations if one is not interested in actually seeing -the result in UCS-4. To avoid trouble with endianess, the internal -representation consistently is named `INTERNAL' even on big-endian -systems where the representations are identical. - -`iconv' module data structures -.............................. - - So far this section has described how modules are located and -considered to be used. What remains to be described is the interface -of the modules so that one can write new ones. This section describes -the interface as it is in use in January 1999. The interface will -change a bit in the future but, with luck, only in an upwardly -compatible way. - - The definitions necessary to write new modules are publicly available -in the non-standard header `gconv.h'. The following text, therefore, -describes the definitions from this header file. First, however, it is -necessary to get an overview. - - From the perspective of the user of `iconv' the interface is quite -simple: the `iconv_open' function returns a handle that can be used in -calls to `iconv', and finally the handle is freed with a call to -`iconv_close'. The problem is that the handle has to be able to -represent the possibly long sequences of conversion steps and also the -state of each conversion since the handle is all that is passed to the -`iconv' function. Therefore, the data structures are really the -elements necessary to understanding the implementation. - - We need two different kinds of data structures. The first describes -the conversion and the second describes the state etc. There are -really two type definitions like this in `gconv.h'. - - - Data type: struct __gconv_step - This data structure describes one conversion a module can perform. - For each function in a loaded module with conversion functions - there is exactly one object of this type. This object is shared - by all users of the conversion (i.e., this object does not contain - any information corresponding to an actual conversion; it only - describes the conversion itself). - - `struct __gconv_loaded_object *__shlib_handle' - `const char *__modname' - `int __counter' - All these elements of the structure are used internally in - the C library to coordinate loading and unloading the shared. - One must not expect any of the other elements to be - available or initialized. - - `const char *__from_name' - `const char *__to_name' - `__from_name' and `__to_name' contain the names of the source - and destination character sets. They can be used to identify - the actual conversion to be carried out since one module - might implement conversions for more than one character set - and/or direction. - - `gconv_fct __fct' - `gconv_init_fct __init_fct' - `gconv_end_fct __end_fct' - These elements contain pointers to the functions in the - loadable module. The interface will be explained below. - - `int __min_needed_from' - `int __max_needed_from' - `int __min_needed_to' - `int __max_needed_to;' - These values have to be supplied in the init function of the - module. The `__min_needed_from' value specifies how many - bytes a character of the source character set at least needs. - The `__max_needed_from' specifies the maximum value that - also includes possible shift sequences. - - The `__min_needed_to' and `__max_needed_to' values serve the - same purpose as `__min_needed_from' and `__max_needed_from' - but this time for the destination character set. - - It is crucial that these values be accurate since otherwise - the conversion functions will have problems or not work at - all. - - `int __stateful' - This element must also be initialized by the init function. - `int __stateful' is nonzero if the source character set is - stateful. Otherwise it is zero. - - `void *__data' - This element can be used freely by the conversion functions - in the module. `void *__data' can be used to communicate - extra information from one call to another. `void *__data' - need not be initialized if not needed at all. If `void - *__data' element is assigned a pointer to dynamically - allocated memory (presumably in the init function) it has to - be made sure that the end function deallocates the memory. - Otherwise the application will leak memory. - - It is important to be aware that this data structure is - shared by all users of this specification conversion and - therefore the `__data' element must not contain data specific - to one specific use of the conversion function. - - - Data type: struct __gconv_step_data - This is the data structure that contains the information specific - to each use of the conversion functions. - - `char *__outbuf' - `char *__outbufend' - These elements specify the output buffer for the conversion - step. The `__outbuf' element points to the beginning of the - buffer, and `__outbufend' points to the byte following the - last byte in the buffer. The conversion function must not - assume anything about the size of the buffer but it can be - safely assumed the there is room for at least one complete - character in the output buffer. - - Once the conversion is finished, if the conversion is the - last step, the `__outbuf' element must be modified to point - after the last byte written into the buffer to signal how - much output is available. If this conversion step is not the - last one, the element must not be modified. The - `__outbufend' element must not be modified. - - `int __is_last' - This element is nonzero if this conversion step is the last - one. This information is necessary for the recursion. See - the description of the conversion function internals below. - This element must never be modified. - - `int __invocation_counter' - The conversion function can use this element to see how many - calls of the conversion function already happened. Some - character sets require a certain prolog when generating - output, and by comparing this value with zero, one can find - out whether it is the first call and whether, therefore, the - prolog should be emitted. This element must never be - modified. - - `int __internal_use' - This element is another one rarely used but needed in certain - situations. It is assigned a nonzero value in case the - conversion functions are used to implement `mbsrtowcs' et.al. - (i.e., the function is not used directly through the `iconv' - interface). - - This sometimes makes a difference as it is expected that the - `iconv' functions are used to translate entire texts while the - `mbsrtowcs' functions are normally used only to convert single - strings and might be used multiple times to convert entire - texts. - - But in this situation we would have problem complying with - some rules of the character set specification. Some - character sets require a prolog, which must appear exactly - once for an entire text. If a number of `mbsrtowcs' calls - are used to convert the text, only the first call must add - the prolog. However, because there is no communication - between the different calls of `mbsrtowcs', the conversion - functions have no possibility to find this out. The - situation is different for sequences of `iconv' calls since - the handle allows access to the needed information. - - The `int __internal_use' element is mostly used together with - `__invocation_counter' as follows: - - if (!data->__internal_use - && data->__invocation_counter == 0) - /* Emit prolog. */ - ... - - This element must never be modified. - - `mbstate_t *__statep' - The `__statep' element points to an object of type `mbstate_t' - (*note Keeping the state::). The conversion of a stateful - character set must use the object pointed to by `__statep' to - store information about the conversion state. The `__statep' - element itself must never be modified. - - `mbstate_t __state' - This element must _never_ be used directly. It is only part - of this structure to have the needed space allocated. - -`iconv' module interfaces -......................... - - With the knowledge about the data structures we now can describe the -conversion function itself. To understand the interface a bit of -knowledge is necessary about the functionality in the C library that -loads the objects with the conversions. - - It is often the case that one conversion is used more than once -(i.e., there are several `iconv_open' calls for the same set of -character sets during one program run). The `mbsrtowcs' et.al. -functions in the GNU C library also use the `iconv' functionality, which -increases the number of uses of the same functions even more. - - Because of this multiple use of conversions, the modules do not get -loaded exclusively for one conversion. Instead a module once loaded can -be used by an arbitrary number of `iconv' or `mbsrtowcs' calls at the -same time. The splitting of the information between conversion- -function-specific information and conversion data makes this possible. -The last section showed the two data structures used to do this. - - This is of course also reflected in the interface and semantics of -the functions that the modules must provide. There are three functions -that must have the following names: - -`gconv_init' - The `gconv_init' function initializes the conversion function - specific data structure. This very same object is shared by all - conversions that use this conversion and, therefore, no state - information about the conversion itself must be stored in here. - If a module implements more than one conversion, the `gconv_init' - function will be called multiple times. - -`gconv_end' - The `gconv_end' function is responsible for freeing all resources - allocated by the `gconv_init' function. If there is nothing to do, - this function can be missing. Special care must be taken if the - module implements more than one conversion and the `gconv_init' - function does not allocate the same resources for all conversions. - -`gconv' - This is the actual conversion function. It is called to convert - one block of text. It gets passed the conversion step information - initialized by `gconv_init' and the conversion data, specific to - this use of the conversion functions. - - There are three data types defined for the three module interface -functions and these define the interface. - - - Data type: int (*__gconv_init_fct) (struct __gconv_step *) - This specifies the interface of the initialization function of the - module. It is called exactly once for each conversion the module - implements. - - As explained in the description of the `struct __gconv_step' data - structure above the initialization function has to initialize - parts of it. - - `__min_needed_from' - `__max_needed_from' - `__min_needed_to' - `__max_needed_to' - These elements must be initialized to the exact numbers of - the minimum and maximum number of bytes used by one character - in the source and destination character sets, respectively. - If the characters all have the same size, the minimum and - maximum values are the same. - - `__stateful' - This element must be initialized to an nonzero value if the - source character set is stateful. Otherwise it must be zero. - - If the initialization function needs to communicate some - information to the conversion function, this communication can - happen using the `__data' element of the `__gconv_step' structure. - But since this data is shared by all the conversions, it must not - be modified by the conversion function. The example below shows - how this can be used. - - #define MIN_NEEDED_FROM 1 - #define MAX_NEEDED_FROM 4 - #define MIN_NEEDED_TO 4 - #define MAX_NEEDED_TO 4 - - int - gconv_init (struct __gconv_step *step) - { - /* Determine which direction. */ - struct iso2022jp_data *new_data; - enum direction dir = illegal_dir; - enum variant var = illegal_var; - int result; - - if (__strcasecmp (step->__from_name, "ISO-2022-JP//") == 0) - { - dir = from_iso2022jp; - var = iso2022jp; - } - else if (__strcasecmp (step->__to_name, "ISO-2022-JP//") == 0) - { - dir = to_iso2022jp; - var = iso2022jp; - } - else if (__strcasecmp (step->__from_name, "ISO-2022-JP-2//") == 0) - { - dir = from_iso2022jp; - var = iso2022jp2; - } - else if (__strcasecmp (step->__to_name, "ISO-2022-JP-2//") == 0) - { - dir = to_iso2022jp; - var = iso2022jp2; - } - - result = __GCONV_NOCONV; - if (dir != illegal_dir) - { - new_data = (struct iso2022jp_data *) - malloc (sizeof (struct iso2022jp_data)); - - result = __GCONV_NOMEM; - if (new_data != NULL) - { - new_data->dir = dir; - new_data->var = var; - step->__data = new_data; - - if (dir == from_iso2022jp) - { - step->__min_needed_from = MIN_NEEDED_FROM; - step->__max_needed_from = MAX_NEEDED_FROM; - step->__min_needed_to = MIN_NEEDED_TO; - step->__max_needed_to = MAX_NEEDED_TO; - } - else - { - step->__min_needed_from = MIN_NEEDED_TO; - step->__max_needed_from = MAX_NEEDED_TO; - step->__min_needed_to = MIN_NEEDED_FROM; - step->__max_needed_to = MAX_NEEDED_FROM + 2; - } - - /* Yes, this is a stateful encoding. */ - step->__stateful = 1; - - result = __GCONV_OK; - } - } - - return result; - } - - The function first checks which conversion is wanted. The module - from which this function is taken implements four different - conversions; which one is selected can be determined by comparing - the names. The comparison should always be done without paying - attention to the case. - - Next, a data structure, which contains the necessary information - about which conversion is selected, is allocated. The data - structure `struct iso2022jp_data' is locally defined since, - outside the module, this data is not used at all. Please note - that if all four conversions this modules supports are requested - there are four data blocks. - - One interesting thing is the initialization of the `__min_' and - `__max_' elements of the step data object. A single ISO-2022-JP - character can consist of one to four bytes. Therefore the - `MIN_NEEDED_FROM' and `MAX_NEEDED_FROM' macros are defined this - way. The output is always the `INTERNAL' character set (aka - UCS-4) and therefore each character consists of exactly four - bytes. For the conversion from `INTERNAL' to ISO-2022-JP we have - to take into account that escape sequences might be necessary to - switch the character sets. Therefore the `__max_needed_to' - element for this direction gets assigned `MAX_NEEDED_FROM + 2'. - This takes into account the two bytes needed for the escape - sequences to single the switching. The asymmetry in the maximum - values for the two directions can be explained easily: when - reading ISO-2022-JP text, escape sequences can be handled alone - (i.e., it is not necessary to process a real character since the - effect of the escape sequence can be recorded in the state - information). The situation is different for the other direction. - Since it is in general not known which character comes next, one - cannot emit escape sequences to change the state in advance. This - means the escape sequences that have to be emitted together with - the next character. Therefore one needs more room than only for - the character itself. - - The possible return values of the initialization function are: - - `__GCONV_OK' - The initialization succeeded - - `__GCONV_NOCONV' - The requested conversion is not supported in the module. - This can happen if the `gconv-modules' file has errors. - - `__GCONV_NOMEM' - Memory required to store additional information could not be - allocated. - - The function called before the module is unloaded is significantly -easier. It often has nothing at all to do; in which case it can be left -out completely. - - - Data type: void (*__gconv_end_fct) (struct gconv_step *) - The task of this function is to free all resources allocated in the - initialization function. Therefore only the `__data' element of - the object pointed to by the argument is of interest. Continuing - the example from the initialization function, the finalization - function looks like this: - - void - gconv_end (struct __gconv_step *data) - { - free (data->__data); - } - - The most important function is the conversion function itself, which -can get quite complicated for complex character sets. But since this -is not of interest here, we will only describe a possible skeleton for -the conversion function. - - - Data type: int (*__gconv_fct) (struct __gconv_step *, struct - __gconv_step_data *, const char **, const char *, size_t *, - int) - The conversion function can be called for two basic reason: to - convert text or to reset the state. From the description of the - `iconv' function it can be seen why the flushing mode is - necessary. What mode is selected is determined by the sixth - argument, an integer. This argument being nonzero means that - flushing is selected. - - Common to both modes is where the output buffer can be found. The - information about this buffer is stored in the conversion step - data. A pointer to this information is passed as the second - argument to this function. The description of the `struct - __gconv_step_data' structure has more information on the - conversion step data. - - What has to be done for flushing depends on the source character - set. If the source character set is not stateful, nothing has to - be done. Otherwise the function has to emit a byte sequence to - bring the state object into the initial state. Once this all - happened the other conversion modules in the chain of conversions - have to get the same chance. Whether another step follows can be - determined from the `__is_last' element of the step data structure - to which the first parameter points. - - The more interesting mode is when actual text has to be converted. - The first step in this case is to convert as much text as - possible from the input buffer and store the result in the output - buffer. The start of the input buffer is determined by the third - argument, which is a pointer to a pointer variable referencing the - beginning of the buffer. The fourth argument is a pointer to the - byte right after the last byte in the buffer. - - The conversion has to be performed according to the current state - if the character set is stateful. The state is stored in an - object pointed to by the `__statep' element of the step data - (second argument). Once either the input buffer is empty or the - output buffer is full the conversion stops. At this point, the - pointer variable referenced by the third parameter must point to - the byte following the last processed byte (i.e., if all of the - input is consumed, this pointer and the fourth parameter have the - same value). - - What now happens depends on whether this step is the last one. If - it is the last step, the only thing that has to be done is to - update the `__outbuf' element of the step data structure to point - after the last written byte. This update gives the caller the - information on how much text is available in the output buffer. - In addition, the variable pointed to by the fifth parameter, which - is of type `size_t', must be incremented by the number of - characters (_not bytes_) that were converted in a non-reversible - way. Then, the function can return. - - In case the step is not the last one, the later conversion - functions have to get a chance to do their work. Therefore, the - appropriate conversion function has to be called. The information - about the functions is stored in the conversion data structures, - passed as the first parameter. This information and the step data - are stored in arrays, so the next element in both cases can be - found by simple pointer arithmetic: - - int - gconv (struct __gconv_step *step, struct __gconv_step_data *data, - const char **inbuf, const char *inbufend, size_t *written, - int do_flush) - { - struct __gconv_step *next_step = step + 1; - struct __gconv_step_data *next_data = data + 1; - ... - - The `next_step' pointer references the next step information and - `next_data' the next data record. The call of the next function - therefore will look similar to this: - - next_step->__fct (next_step, next_data, &outerr, outbuf, - written, 0) - - But this is not yet all. Once the function call returns the - conversion function might have some more to do. If the return - value of the function is `__GCONV_EMPTY_INPUT', more room is - available in the output buffer. Unless the input buffer is empty - the conversion, functions start all over again and process the - rest of the input buffer. If the return value is not - `__GCONV_EMPTY_INPUT', something went wrong and we have to recover - from this. - - A requirement for the conversion function is that the input buffer - pointer (the third argument) always point to the last character - that was put in converted form into the output buffer. This is - trivially true after the conversion performed in the current step, - but if the conversion functions deeper downstream stop - prematurely, not all characters from the output buffer are - consumed and, therefore, the input buffer pointers must be backed - off to the right position. - - Correcting the input buffers is easy to do if the input and output - character sets have a fixed width for all characters. In this - situation we can compute how many characters are left in the - output buffer and, therefore, can correct the input buffer pointer - appropriately with a similar computation. Things are getting - tricky if either character set has characters represented with - variable length byte sequences, and it gets even more complicated - if the conversion has to take care of the state. In these cases - the conversion has to be performed once again, from the known - state before the initial conversion (i.e., if necessary the state - of the conversion has to be reset and the conversion loop has to be - executed again). The difference now is that it is known how much - input must be created, and the conversion can stop before - converting the first unused character. Once this is done the - input buffer pointers must be updated again and the function can - return. - - One final thing should be mentioned. If it is necessary for the - conversion to know whether it is the first invocation (in case a - prolog has to be emitted), the conversion function should - increment the `__invocation_counter' element of the step data - structure just before returning to the caller. See the - description of the `struct __gconv_step_data' structure above for - more information on how this can be used. - - The return value must be one of the following values: - - `__GCONV_EMPTY_INPUT' - All input was consumed and there is room left in the output - buffer. - - `__GCONV_FULL_OUTPUT' - No more room in the output buffer. In case this is not the - last step this value is propagated down from the call of the - next conversion function in the chain. - - `__GCONV_INCOMPLETE_INPUT' - The input buffer is not entirely empty since it contains an - incomplete character sequence. - - The following example provides a framework for a conversion - function. In case a new conversion has to be written the holes in - this implementation have to be filled and that is it. - - int - gconv (struct __gconv_step *step, struct __gconv_step_data *data, - const char **inbuf, const char *inbufend, size_t *written, - int do_flush) - { - struct __gconv_step *next_step = step + 1; - struct __gconv_step_data *next_data = data + 1; - gconv_fct fct = next_step->__fct; - int status; - - /* If the function is called with no input this means we have - to reset to the initial state. The possibly partly - converted input is dropped. */ - if (do_flush) - { - status = __GCONV_OK; - - /* Possible emit a byte sequence which put the state object - into the initial state. */ - - /* Call the steps down the chain if there are any but only - if we successfully emitted the escape sequence. */ - if (status == __GCONV_OK && ! data->__is_last) - status = fct (next_step, next_data, NULL, NULL, - written, 1); - } - else - { - /* We preserve the initial values of the pointer variables. */ - const char *inptr = *inbuf; - char *outbuf = data->__outbuf; - char *outend = data->__outbufend; - char *outptr; - - do - { - /* Remember the start value for this round. */ - inptr = *inbuf; - /* The outbuf buffer is empty. */ - outptr = outbuf; - - /* For stateful encodings the state must be safe here. */ - - /* Run the conversion loop. `status' is set - appropriately afterwards. */ - - /* If this is the last step, leave the loop. There is - nothing we can do. */ - if (data->__is_last) - { - /* Store information about how many bytes are - available. */ - data->__outbuf = outbuf; - - /* If any non-reversible conversions were performed, - add the number to `*written'. */ - - break; - } - - /* Write out all output that was produced. */ - if (outbuf > outptr) - { - const char *outerr = data->__outbuf; - int result; - - result = fct (next_step, next_data, &outerr, - outbuf, written, 0); - - if (result != __GCONV_EMPTY_INPUT) - { - if (outerr != outbuf) - { - /* Reset the input buffer pointer. We - document here the complex case. */ - size_t nstatus; - - /* Reload the pointers. */ - *inbuf = inptr; - outbuf = outptr; - - /* Possibly reset the state. */ - - /* Redo the conversion, but this time - the end of the output buffer is at - `outerr'. */ - } - - /* Change the status. */ - status = result; - } - else - /* All the output is consumed, we can make - another run if everything was ok. */ - if (status == __GCONV_FULL_OUTPUT) - status = __GCONV_OK; - } - } - while (status == __GCONV_OK); - - /* We finished one use of this step. */ - ++data->__invocation_counter; - } - - return status; - } - - This information should be sufficient to write new modules.

For example, all your program -needs to do in order to use the collating sequence of the chosen locale -is to use `strcoll' or `strxfrm' to compare strings. - - Other aspects of locales are beyond the comprehension of the library. -For example, the library can't automatically translate your program's -output messages into other languages. The only way you can support -output in the user's favorite language is to program this more or less -by hand. The C library provides functions to handle translations for -multiple languages easily. - - This chapter discusses the mechanism by which you can modify the -current locale. The effects of the current locale on specific library -functions are discussed in more detail in the descriptions of those -functions. - - -File: libc.info, Node: Choosing Locale, Next: Locale Categories, Prev: Effects of Locale, Up: Locales - -Choosing a Locale -================= - - The simplest way for the user to choose a locale is to set the -environment variable `LANG'. This specifies a single locale to use for -all purposes. For example, a user could specify a hypothetical locale -named `espana-castellano' to use the standard conventions of most of -Spain. - - The set of locales supported depends on the operating system you are -using, and so do their names. We can't make any promises about what -locales will exist, except for one standard locale called `C' or -`POSIX'. Later we will describe how to construct locales. - - A user also has the option of specifying different locales for -different purposes--in effect, choosing a mixture of multiple locales. - - For example, the user might specify the locale `espana-castellano' -for most purposes, but specify the locale `usa-english' for currency -formatting. This might make sense if the user is a Spanish-speaking -American, working in Spanish, but representing monetary amounts in US -dollars. - - Note that both locales `espana-castellano' and `usa-english', like -all locales, would include conventions for all of the purposes to which -locales apply. However, the user can choose to use each locale for a -particular subset of those purposes. - - -File: libc.info, Node: Locale Categories, Next: Setting the Locale, Prev: Choosing Locale, Up: Locales - -Categories of Activities that Locales Affect -============================================ - - The purposes that locales serve are grouped into "categories", so -that a user or a program can choose the locale for each category -independently. Here is a table of categories; each name is both an -environment variable that a user can set, and a macro name that you can -use as an argument to `setlocale'. - -`LC_COLLATE' - This category applies to collation of strings (functions `strcoll' - and `strxfrm'); see *Note Collation Functions::. - -`LC_CTYPE' - This category applies to classification and conversion of - characters, and to multibyte and wide characters; see *Note - Character Handling::, and *Note Character Set Handling::. - -`LC_MONETARY' - This category applies to formatting monetary values; see *Note - General Numeric::. - -`LC_NUMERIC' - This category applies to formatting numeric values that are not - monetary; see *Note General Numeric::. - -`LC_TIME' - This category applies to formatting date and time values; see - *Note Formatting Calendar Time::. - -`LC_MESSAGES' - This category applies to selecting the language used in the user - interface for message translation (*note The Uniforum approach::; - *note Message catalogs a la X/Open::) and contains regular - expressions for affirmative and negative responses. - -`LC_ALL' - This is not an environment variable; it is only a macro that you - can use with `setlocale' to set a single locale for all purposes. - Setting this environment variable overwrites all selections by the - other `LC_*' variables or `LANG'. - -`LANG' - If this environment variable is defined, its value specifies the - locale to use for all purposes except as overridden by the - variables above. - - When developing the message translation functions it was felt that -the functionality provided by the variables above is not sufficient. -For example, it should be possible to specify more than one locale name. -Take a Swedish user who better speaks German than English, and a program -whose messages are output in English by default. It should be possible -to specify that the first choice of language is Swedish, the second -German, and if this also fails to use English. This is possible with -the variable `LANGUAGE'.

This happens automatically. However, these variables do not -automatically control the locale used by the library functions, because -ISO C says that all programs start by default in the standard `C' -locale. To use the locales specified by the environment, you must call -`setlocale'. Call it as follows: - - setlocale (LC_ALL, ""); - -to select a locale based on the user choice of the appropriate -environment variables. - - You can also use `setlocale' to specify a particular locale, for -general use or for a specific category. - - The symbols in this section are defined in the header file -`locale.h'. - - - Function: char * setlocale (int CATEGORY, const char *LOCALE) - The function `setlocale' sets the current locale for category - CATEGORY to LOCALE. A list of all the locales the system provides - can be created by running - - locale -a - - If CATEGORY is `LC_ALL', this specifies the locale for all - purposes. The other possible values of CATEGORY specify an single - purpose (*note Locale Categories::). - - You can also use this function to find out the current locale by - passing a null pointer as the LOCALE argument. In this case, - `setlocale' returns a string that is the name of the locale - currently selected for category CATEGORY. - - The string returned by `setlocale' can be overwritten by subsequent - calls, so you should make a copy of the string (*note Copying and - Concatenation::) if you want to save it past any further calls to - `setlocale'. (The standard library is guaranteed never to call - `setlocale' itself.) - - You should not modify the string returned by `setlocale'. It might - be the same string that was passed as an argument in a previous - call to `setlocale'. One requirement is that the CATEGORY must be - the same in the call the string was returned and the one when the - string is passed in as LOCALE parameter. - - When you read the current locale for category `LC_ALL', the value - encodes the entire combination of selected locales for all - categories. In this case, the value is not just a single locale - name. In fact, we don't make any promises about what it looks - like. But if you specify the same "locale name" with `LC_ALL' in - a subsequent call to `setlocale', it restores the same combination - of locale selections. - - To be sure you can use the returned string encoding the currently - selected locale at a later time, you must make a copy of the - string. It is not guaranteed that the returned pointer remains - valid over time. - - When the LOCALE argument is not a null pointer, the string returned - by `setlocale' reflects the newly-modified locale. - - If you specify an empty string for LOCALE, this means to read the - appropriate environment variable and use its value to select the - locale for CATEGORY. - - If a nonempty string is given for LOCALE, then the locale of that - name is used if possible. - - If you specify an invalid locale name, `setlocale' returns a null - pointer and leaves the current locale unchanged. - - Here is an example showing how you might use `setlocale' to -temporarily switch to a new locale. - - #include - #include - #include - #include - - void - with_other_locale (char *new_locale, - void (*subroutine) (int), - int argument) - { - char *old_locale, *saved_locale; - - /* Get the name of the current locale. */ - old_locale = setlocale (LC_ALL, NULL); - - /* Copy the name so it won't be clobbered by `setlocale'. */ - saved_locale = strdup (old_locale); - if (saved_locale == NULL) - fatal ("Out of memory"); - - /* Now change the locale and do some stuff with it. */ - setlocale (LC_ALL, new_locale); - (*subroutine) (argument); - - /* Restore the original locale. */ - setlocale (LC_ALL, saved_locale); - free (saved_locale); - } - - *Portability Note:* Some ISO C systems may define additional locale -categories, and future versions of the library will do so. For -portability, assume that any symbol beginning with `LC_' might be -defined in `locale.h'. - - -File: libc.info, Node: Standard Locales, Next: Locale Information, Prev: Setting the Locale, Up: Locales - -Standard Locales -================ - - The only locale names you can count on finding on all operating -systems are these three standard ones: - -`"C"' - This is the standard C locale. The attributes and behavior it - provides are specified in the ISO C standard. When your program - starts up, it initially uses this locale by default. - -`"POSIX"' - This is the standard POSIX locale. Currently, it is an alias for - the standard C locale. - -`""' - The empty name says to select a locale based on environment - variables. *Note Locale Categories::. - - Defining and installing named locales is normally a responsibility of -the system administrator at your site (or the person who installed the -GNU C library). It is also possible for the user to create private -locales. All this will be discussed later when describing the tool to -do so. - - If your program needs to use something other than the `C' locale, it -will be more portable if you use whatever locale the user specifies -with the environment, rather than trying to specify some non-standard -locale explicitly by name. Remember, different machines might have -different sets of locales installed. - - -File: libc.info, Node: Locale Information, Next: Formatting Numbers, Prev: Standard Locales, Up: Locales - -Accessing Locale Information -============================ - - There are several ways to access locale information. The simplest -way is to let the C library itself do the work. Several of the -functions in this library implicitly access the locale data, and use -what information is provided by the currently selected locale. This is -how the locale model is meant to work normally. - - As an example take the `strftime' function, which is meant to nicely -format date and time information (*note Formatting Calendar Time::). -Part of the standard information contained in the `LC_TIME' category is -the names of the months. Instead of requiring the programmer to take -care of providing the translations the `strftime' function does this -all by itself. `%A' in the format string is replaced by the -appropriate weekday name of the locale currently selected by `LC_TIME'. -This is an easy example, and wherever possible functions do things -automatically in this way. - - But there are quite often situations when there is simply no function -to perform the task, or it is simply not possible to do the work -automatically. For these cases it is necessary to access the -information in the locale directly. To do this the C library provides -two functions: `localeconv' and `nl_langinfo'. The former is part of -ISO C and therefore portable, but has a brain-damaged interface. The -second is part of the Unix interface and is portable in as far as the -system follows the Unix standards. - -* Menu: - -* The Lame Way to Locale Data:: ISO C's `localeconv'. -* The Elegant and Fast Way:: X/Open's `nl_langinfo'. - - -File: libc.info, Node: The Lame Way to Locale Data, Next: The Elegant and Fast Way, Up: Locale Information - -`localeconv': It is portable but ... ------------------------------------- - - Together with the `setlocale' function the ISO C people invented the -`localeconv' function. It is a masterpiece of poor design. It is -expensive to use, not extendable, and not generally usable as it -provides access to only `LC_MONETARY' and `LC_NUMERIC' related -information. Nevertheless, if it is applicable to a given situation it -should be used since it is very portable. The function `strfmon' -formats monetary amounts according to the selected locale using this -information. - - - Function: struct lconv * localeconv (void) - The `localeconv' function returns a pointer to a structure whose - components contain information about how numeric and monetary - values should be formatted in the current locale. - - You should not modify the structure or its contents. The - structure might be overwritten by subsequent calls to - `localeconv', or by calls to `setlocale', but no other function in - the library overwrites this value. - - - Data Type: struct lconv - `localeconv''s return value is of this data type. Its elements are - described in the following subsections. - - If a member of the structure `struct lconv' has type `char', and the -value is `CHAR_MAX', it means that the current locale has no value for -that parameter. - -* Menu: - -* General Numeric:: Parameters for formatting numbers and - currency amounts. -* Currency Symbol:: How to print the symbol that identifies an - amount of money (e.g. `$'). -* Sign of Money Amount:: How to print the (positive or negative) sign - for a monetary amount, if one exists. - - -File: libc.info, Node: General Numeric, Next: Currency Symbol, Up: The Lame Way to Locale Data - -Generic Numeric Formatting Parameters -..................................... - - These are the standard members of `struct lconv'; there may be -others. - -`char *decimal_point' -`char *mon_decimal_point' - These are the decimal-point separators used in formatting - non-monetary and monetary quantities, respectively. In the `C' - locale, the value of `decimal_point' is `"."', and the value of - `mon_decimal_point' is `""'. - -`char *thousands_sep' -`char *mon_thousands_sep' - These are the separators used to delimit groups of digits to the - left of the decimal point in formatting non-monetary and monetary - quantities, respectively. In the `C' locale, both members have a - value of `""' (the empty string). - -`char *grouping' -`char *mon_grouping' - These are strings that specify how to group the digits to the left - of the decimal point. `grouping' applies to non-monetary - quantities and `mon_grouping' applies to monetary quantities. Use - either `thousands_sep' or `mon_thousands_sep' to separate the digit - groups. - - Each member of these strings is to be interpreted as an integer - value of type `char'. Successive numbers (from left to right) - give the sizes of successive groups (from right to left, starting - at the decimal point.) The last member is either `0', in which - case the previous member is used over and over again for all the - remaining groups, or `CHAR_MAX', in which case there is no more - grouping--or, put another way, any remaining digits form one large - group without separators. - - For example, if `grouping' is `"\04\03\02"', the correct grouping - for the number `123456787654321' is `12', `34', `56', `78', `765', - `4321'. This uses a group of 4 digits at the end, preceded by a - group of 3 digits, preceded by groups of 2 digits (as many as - needed). With a separator of `,', the number would be printed as - `12,34,56,78,765,4321'. - - A value of `"\03"' indicates repeated groups of three digits, as - normally used in the U.S. - - In the standard `C' locale, both `grouping' and `mon_grouping' - have a value of `""'. This value specifies no grouping at all. - -`char int_frac_digits' -`char frac_digits' - These are small integers indicating how many fractional digits (to - the right of the decimal point) should be displayed in a monetary - value in international and local formats, respectively. (Most - often, both members have the same value.) - - In the standard `C' locale, both of these members have the value - `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say - what to do when you find this value; we recommend printing no - fractional digits. (This locale also specifies the empty string - for `mon_decimal_point', so printing any fractional digits would be - confusing!) - - -File: libc.info, Node: Currency Symbol, Next: Sign of Money Amount, Prev: General Numeric, Up: The Lame Way to Locale Data - -Printing the Currency Symbol -............................ - - These members of the `struct lconv' structure specify how to print -the symbol to identify a monetary value--the international analog of -`$' for US dollars. - - Each country has two standard currency symbols. The "local currency -symbol" is used commonly within the country, while the "international -currency symbol" is used internationally to refer to that country's -currency when it is necessary to indicate the country unambiguously. - - For example, many countries use the dollar as their monetary unit, -and when dealing with international currencies it's important to specify -that one is dealing with (say) Canadian dollars instead of U.S. dollars -or Australian dollars. But when the context is known to be Canada, -there is no need to make this explicit--dollar amounts are implicitly -assumed to be in Canadian dollars. - -`char *currency_symbol' - The local currency symbol for the selected locale. - - In the standard `C' locale, this member has a value of `""' (the - empty string), meaning "unspecified". The ISO standard doesn't - say what to do when you find this value; we recommend you simply - print the empty string as you would print any other string pointed - to by this variable. - -`char *int_curr_symbol' - The international currency symbol for the selected locale. - - The value of `int_curr_symbol' should normally consist of a - three-letter abbreviation determined by the international standard - `ISO 4217 Codes for the Representation of Currency and Funds', - followed by a one-character separator (often a space). - - In the standard `C' locale, this member has a value of `""' (the - empty string), meaning "unspecified". We recommend you simply - print the empty string as you would print any other string pointed - to by this variable. - -`char p_cs_precedes' -`char n_cs_precedes' -`char int_p_cs_precedes' -`char int_n_cs_precedes' - These members are `1' if the `currency_symbol' or - `int_curr_symbol' strings should precede the value of a monetary - amount, or `0' if the strings should follow the value. The - `p_cs_precedes' and `int_p_cs_precedes' members apply to positive - amounts (or zero), and the `n_cs_precedes' and `int_n_cs_precedes' - members apply to negative amounts. - - In the standard `C' locale, all of these members have a value of - `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say - what to do when you find this value. We recommend printing the - currency symbol before the amount, which is right for most - countries. In other words, treat all nonzero values alike in - these members. - - The members with the `int_' prefix apply to the `int_curr_symbol' - while the other two apply to `currency_symbol'. - -`char p_sep_by_space' -`char n_sep_by_space' -`char int_p_sep_by_space' -`char int_n_sep_by_space' - These members are `1' if a space should appear between the - `currency_symbol' or `int_curr_symbol' strings and the amount, or - `0' if no space should appear. The `p_sep_by_space' and - `int_p_sep_by_space' members apply to positive amounts (or zero), - and the `n_sep_by_space' and `int_n_sep_by_space' members apply to - negative amounts. - - In the standard `C' locale, all of these members have a value of - `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say - what you should do when you find this value; we suggest you treat - it as 1 (print a space). In other words, treat all nonzero values - alike in these members. - - The members with the `int_' prefix apply to the `int_curr_symbol' - while the other two apply to `currency_symbol'. There is one - specialty with the `int_curr_symbol', though. Since all legal - values contain a space at the end the string one either printf - this space (if the currency symbol must appear in front and must - be separated) or one has to avoid printing this character at all - (especially when at the end of the string). - - -File: libc.info, Node: Sign of Money Amount, Prev: Currency Symbol, Up: The Lame Way to Locale Data - -Printing the Sign of a Monetary Amount -...................................... - - These members of the `struct lconv' structure specify how to print -the sign (if any) of a monetary value. - -`char *positive_sign' -`char *negative_sign' - These are strings used to indicate positive (or zero) and negative - monetary quantities, respectively. - - In the standard `C' locale, both of these members have a value of - `""' (the empty string), meaning "unspecified". - - The ISO standard doesn't say what to do when you find this value; - we recommend printing `positive_sign' as you find it, even if it is - empty.

The information which was meant to be available in -the locale (as later specified in the POSIX.1 standard) requires more -ways to access it. Therefore the `nl_langinfo' function was introduced. - - - Function: char * nl_langinfo (nl_item ITEM) - The `nl_langinfo' function can be used to access individual - elements of the locale categories. Unlike the `localeconv' - function, which returns all the information, `nl_langinfo' lets - the caller select what information it requires. This is very fast - and it is not a problem to call this function multiple times. - - A second advantage is that in addition to the numeric and monetary - formatting information, information from the `LC_TIME' and - `LC_MESSAGES' categories is available. - - The type `nl_type' is defined in `nl_types.h'. The argument ITEM - is a numeric value defined in the header `langinfo.h'. The X/Open - standard defines the following values: - - `CODESET' - `nl_langinfo' returns a string with the name of the coded - character set used in the selected locale. - - `ABDAY_1' - `ABDAY_2' - `ABDAY_3' - `ABDAY_4' - `ABDAY_5' - `ABDAY_6' - `ABDAY_7' - `nl_langinfo' returns the abbreviated weekday name. `ABDAY_1' - corresponds to Sunday. - - `DAY_1' - `DAY_2' - `DAY_3' - `DAY_4' - `DAY_5' - `DAY_6' - `DAY_7' - Similar to `ABDAY_1' etc., but here the return value is the - unabbreviated weekday name. - - `ABMON_1' - `ABMON_2' - `ABMON_3' - `ABMON_4' - `ABMON_5' - `ABMON_6' - `ABMON_7' - `ABMON_8' - `ABMON_9' - `ABMON_10' - `ABMON_11' - `ABMON_12' - The return value is abbreviated name of the month. `ABMON_1' - corresponds to January. - - `MON_1' - `MON_2' - `MON_3' - `MON_4' - `MON_5' - `MON_6' - `MON_7' - `MON_8' - `MON_9' - `MON_10' - `MON_11' - `MON_12' - Similar to `ABMON_1' etc., but here the month names are not - abbreviated. Here the first value `MON_1' also corresponds - to January. - - `AM_STR' - `PM_STR' - The return values are strings which can be used in the - representation of time as an hour from 1 to 12 plus an am/pm - specifier. - - Note that in locales which do not use this time representation - these strings might be empty, in which case the am/pm format - cannot be used at all. - - `D_T_FMT' - The return value can be used as a format string for - `strftime' to represent time and date in a locale-specific - way. - - `D_FMT' - The return value can be used as a format string for - `strftime' to represent a date in a locale-specific way. - - `T_FMT' - The return value can be used as a format string for - `strftime' to represent time in a locale-specific way. - - `T_FMT_AMPM' - The return value can be used as a format string for - `strftime' to represent time in the am/pm format. - - Note that if the am/pm format does not make any sense for the - selected locale, the return value might be the same as the - one for `T_FMT'. - - `ERA' - The return value represents the era used in the current - locale. - - Most locales do not define this value. An example of a - locale which does define this value is the Japanese one. In - Japan, the traditional representation of dates includes the - name of the era corresponding to the then-emperor's reign. - - Normally it should not be necessary to use this value - directly. Specifying the `E' modifier in their format - strings causes the `strftime' functions to use this - information. The format of the returned string is not - specified, and therefore you should not assume knowledge of - it on different systems. - - `ERA_YEAR' - The return value gives the year in the relevant era of the - locale.

If the user has not selected any locale for the - appropriate category, `nl_langinfo' returns the information from - the `"C"' locale. It is therefore possible to use this function as - shown in the example below. - - If the argument ITEM is not valid, a pointer to an empty string is - returned. - - An example of `nl_langinfo' usage is a function which has to print a -given date and time in a locale-specific way.

Wrong! The output produced is something like -`"hh:mm:ss MM/DD/YY"'. This format is only recognizable in the USA. -Other countries use different formats. Therefore the function should -be rewritten like this: - - size_t - i18n_time_n_data (char *s, size_t len, const struct tm *tp) - { - return strftime (s, len, nl_langinfo (D_T_FMT), tp); - } - - Now it uses the date and time format of the locale selected when the -program runs. If the user selects the locale correctly there should -never be a misunderstanding over the time and date format. - - -File: libc.info, Node: Formatting Numbers, Next: Yes-or-No Questions, Prev: Locale Information, Up: Locales - -A dedicated function to format numbers -====================================== - - We have seen that the structure returned by `localeconv' as well as -the values given to `nl_langinfo' allow you to retrieve the various -pieces of locale-specific information to format numbers and monetary -amounts. We have also seen that the underlying rules are quite complex. - - Therefore the X/Open standards introduce a function which uses such -locale information, making it easier for the user to format numbers -according to these rules. - - - Function: ssize_t strfmon (char *S, size_t MAXSIZE, const char - *FORMAT, ...) - The `strfmon' function is similar to the `strftime' function in - that it takes a buffer, its size, a format string, and values to - write into the buffer as text in a form specified by the format - string. Like `strftime', the function also returns the number of - bytes written into the buffer. - - There are two differences: `strfmon' can take more than one - argument, and, of course, the format specification is different. - Like `strftime', the format string consists of normal text, which - is output as is, and format specifiers, which are indicated by a - `%'. Immediately after the `%', you can optionally specify - various flags and formatting information before the main - formatting character, in a similar way to `printf': - - * Immediately following the `%' there can be one or more of the - following flags: - `=F' - The single byte character F is used for this field as - the numeric fill character. By default this character - is a space character. Filling with this character is - only performed if a left precision is specified. It is - not just to fill to the given field width. - - `^' - The number is printed without grouping the digits - according to the rules of the current locale. By - default grouping is enabled. - - `+', `(' - At most one of these flags can be used. They select - which format to represent the sign of a currency amount. - By default, and if `+' is given, the locale equivalent - of +/- is used. If `(' is given, negative amounts are - enclosed in parentheses. The exact format is determined - by the values of the `LC_MONETARY' category of the - locale selected at program runtime. - - `!' - The output will not contain the currency symbol. - - `-' - The output will be formatted left-justified instead of - right-justified if it does not fill the entire field - width. - - The next part of a specification is an optional field width. If no - width is specified 0 is taken. During output, the function first - determines how much space is required. If it requires at least as - many characters as given by the field width, it is output using as - much space as necessary. Otherwise, it is extended to use the - full width by filling with the space character. The presence or - absence of the `-' flag determines the side at which such padding - occurs. If present, the spaces are added at the right making the - output left-justified, and vice versa. - - So far the format looks familiar, being similar to the `printf' and - `strftime' formats. However, the next two optional fields - introduce something new. The first one is a `#' character followed - by a decimal digit string. The value of the digit string - specifies the number of _digit_ positions to the left of the - decimal point (or equivalent). This does _not_ include the - grouping character when the `^' flag is not given. If the space - needed to print the number does not fill the whole width, the - field is padded at the left side with the fill character, which - can be selected using the `=' flag and by default is a space. For - example, if the field width is selected as 6 and the number is - 123, the fill character is `*' the result will be `***123'. - - The second optional field starts with a `.' (period) and consists - of another decimal digit string. Its value describes the number of - characters printed after the decimal point. The default is - selected from the current locale (`frac_digits', - `int_frac_digits', see *note General Numeric::). If the exact - representation needs more digits than given by the field width, - the displayed value is rounded. If the number of fractional - digits is selected to be zero, no decimal point is printed. - - As a GNU extension, the `strfmon' implementation in the GNU libc - allows an optional `L' next as a format modifier. If this modifier - is given, the argument is expected to be a `long double' instead of - a `double' value. - - Finally, the last component is a format specifier. There are three - specifiers defined: - - `i' - Use the locale's rules for formatting an international - currency value. - - `n' - Use the locale's rules for formatting a national currency - value. - - `%' - Place a `%' in the output. There must be no flag, width - specifier or modifier given, only `%%' is allowed. - - As for `printf', the function reads the format string from left to - right and uses the values passed to the function following the - format string. The values are expected to be either of type - `double' or `long double', depending on the presence of the - modifier `L'. The result is stored in the buffer pointed to by S. - At most MAXSIZE characters are stored. - - The return value of the function is the number of characters - stored in S, including the terminating `NULL' byte. If the number - of characters stored would exceed MAXSIZE, the function returns -1 - and the content of the buffer S is unspecified. In this case - `errno' is set to `E2BIG'. - - A few examples should make clear how the function works. It is -assumed that all the following pieces of code are executed in a program -which uses the USA locale (`en_US'). The simplest form of the format -is this: - - strfmon (buf, 100, "@%n@%n@%n@", 123.45, -567.89, 12345.678); - -The output produced is - "@$123.45@-$567.89@$12,345.68@" - - We can notice several things here. First, the widths of the output -numbers are different. We have not specified a width in the format -string, and so this is no wonder. Second, the third number is printed -using thousands separators. The thousands separator for the `en_US' -locale is a comma. The number is also rounded. .678 is rounded to .68 -since the format does not specify a precision and the default value in -the locale is 2. Finally, note that the national currency symbol is -printed since `%n' was used, not `i'. The next example shows how we -can align the output. - - strfmon (buf, 100, "@%=*11n@%=*11n@%=*11n@", 123.45, -567.89, 12345.678); - -The output this time is: - - "@ $123.45@ -$567.89@ $12,345.68@" - - Two things stand out. Firstly, all fields have the same width -(eleven characters) since this is the width given in the format and -since no number required more characters to be printed. The second -important point is that the fill character is not used. This is -correct since the white space was not used to achieve a precision given -by a `#' modifier, but instead to fill to the given width. The -difference becomes obvious if we now add a width specification. - - strfmon (buf, 100, "@%=*11#5n@%=*11#5n@%=*11#5n@", - 123.45, -567.89, 12345.678); - -The output is - - "@ $***123.45@-$***567.89@ $12,456.68@" - - Here we can see that all the currency symbols are now aligned, and -that the space between the currency sign and the number is filled with -the selected fill character. Note that although the width is selected -to be 5 and 123.45 has three digits left of the decimal point, the -space is filled with three asterisks. This is correct since, as -explained above, the width does not include the positions used to store -thousands separators. One last example should explain the remaining -functionality. - - strfmon (buf, 100, "@%=0(16#5.3i@%=0(16#5.3i@%=0(16#5.3i@", - 123.45, -567.89, 12345.678); - -This rather complex format string produces the following output: - - "@ USD 000123,450 @(USD 000567.890)@ USD 12,345.678 @" - - The most noticeable change is the alternative way of representing -negative numbers. In financial circles this is often done using -parentheses, and this is what the `(' flag selected. The fill -character is now `0'. Note that this `0' character is not regarded as -a numeric zero, and therefore the first and second numbers are not -printed using a thousands separator. Since we used the format -specifier `i' instead of `n', the international form of the currency -symbol is used. This is a four letter string, in this case `"USD "'. -The last point is that since the precision right of the decimal point -is selected to be three, the first and second numbers are printed with -an extra zero at the end and the third number is printed without -rounding. - - -File: libc.info, Node: Yes-or-No Questions, Prev: Formatting Numbers, Up: Locales - -Yes-or-No Questions -=================== - - Some non GUI programs ask a yes-or-no question.

The return value is of an - opaque type and can be used in calls to the other functions to - refer to this loaded catalog. - - The return value is `(nl_catd) -1' in case the function failed and - no catalog was loaded. The global variable ERRNO contains a code - for the error causing the failure. But even if the function call - succeeded this does not mean that all messages can be translated. - - Locating the catalog file must happen in a way which lets the user - of the program influence the decision. It is up to the user to - decide about the language to use and sometimes it is useful to use - alternate catalog files. All this can be specified by the user by - setting some environment variables. - - The first problem is to find out where all the message catalogs are - stored. Every program could have its own place to keep all the - different files but usually the catalog files are grouped by - languages and the catalogs for all programs are kept in the same - place. - - To tell the `catopen' function where the catalog for the program - can be found the user can set the environment variable `NLSPATH' to - a value which describes her/his choice. Since this value must be - usable for different languages and locales it cannot be a simple - string. Instead it is a format string (similar to `printf''s). - An example is - - /usr/share/locale/%L/%N:/usr/share/locale/%L/LC_MESSAGES/%N - - First one can see that more than one directory can be specified - (with the usual syntax of separating them by colons). The next - things to observe are the format string, `%L' and `%N' in this - case. The `catopen' function knows about several of them and the - replacement for all of them is of course different. - - `%N' - This format element is substituted with the name of the - catalog file. This is the value of the CAT_NAME argument - given to `catgets'. - - `%L' - This format element is substituted with the name of the - currently selected locale for translating messages. How this - is determined is explained below. - - `%l' - (This is the lowercase ell.) This format element is - substituted with the language element of the locale name. - The string describing the selected locale is expected to have - the form `LANG[_TERR[.CODESET]]' and this format uses the - first part LANG. - - `%t' - This format element is substituted by the territory part TERR - of the name of the currently selected locale. See the - explanation of the format above. - - `%c' - This format element is substituted by the codeset part - CODESET of the name of the currently selected locale. See - the explanation of the format above. - - `%%' - Since `%' is used in a meta character there must be a way to - express the `%' character in the result itself. Using `%%' - does this just like it works for `printf'. - - Using `NLSPATH' allows arbitrary directories to be searched for - message catalogs while still allowing different languages to be - used. If the `NLSPATH' environment variable is not set, the - default value is - - PREFIX/share/locale/%L/%N:PREFIX/share/locale/%L/LC_MESSAGES/%N - - where PREFIX is given to `configure' while installing the GNU C - Library (this value is in many cases `/usr' or the empty string). - - The remaining problem is to decide which must be used. The value - decides about the substitution of the format elements mentioned - above. First of all the user can specify a path in the message - catalog name (i.e., the name contains a slash character). In this - situation the `NLSPATH' environment variable is not used. The - catalog must exist as specified in the program, perhaps relative - to the current working directory. This situation in not desirable - and catalogs names never should be written this way. Beside this, - this behavior is not portable to all other platforms providing the - `catgets' interface. - - Otherwise the values of environment variables from the standard - environment are examined (*note Standard Environment::). Which - variables are examined is decided by the FLAG parameter of - `catopen'. If the value is `NL_CAT_LOCALE' (which is defined in - `nl_types.h') then the `catopen' function use the name of the - locale currently selected for the `LC_MESSAGES' category. - - If FLAG is zero the `LANG' environment variable is examined. This - is a left-over from the early days where the concept of the locales - had not even reached the level of POSIX locales. - - The environment variable and the locale name should have a value - of the form `LANG[_TERR[.CODESET]]' as explained above. If no - environment variable is set the `"C"' locale is used which - prevents any translation. - - The return value of the function is in any case a valid string. - Either it is a translation from a message catalog or it is the - same as the STRING parameter. So a piece of code to decide - whether a translation actually happened must look like this: - - { - char *trans = catgets (desc, set, msg, input_string); - if (trans == input_string) - { - /* Something went wrong. */ - } - } - - When an error occurred the global variable ERRNO is set to - - EBADF - The catalog does not exist. - - ENOMSG - The set/message tuple does not name an existing element in the - message catalog. - - While it sometimes can be useful to test for errors programs - normally will avoid any test. If the translation is not available - it is no big problem if the original, untranslated message is - printed. Either the user understands this as well or s/he will - look for the reason why the messages are not translated. - - Please note that the currently selected locale does not depend on a -call to the `setlocale' function. It is not necessary that the locale -data files for this locale exist and calling `setlocale' succeeds. The -`catopen' function directly reads the values of the environment -variables. - - - Function: char * catgets (nl_catd CATALOG_DESC, int SET, int - MESSAGE, const char *STRING) - The function `catgets' has to be used to access the massage catalog - previously opened using the `catopen' function. The CATALOG_DESC - parameter must be a value previously returned by `catopen'. - - The next two parameters, SET and MESSAGE, reflect the internal - organization of the message catalog files. This will be explained - in detail below. For now it is interesting to know that a catalog - can consists of several set and the messages in each thread are - individually numbered using numbers. Neither the set number nor - the message number must be consecutive. They can be arbitrarily - chosen. But each message (unless equal to another one) must have - its own unique pair of set and message number. - - Since it is not guaranteed that the message catalog for the - language selected by the user exists the last parameter STRING - helps to handle this case gracefully. If no matching string can - be found STRING is returned. This means for the programmer that - - * the STRING parameters should contain reasonable text (this - also helps to understand the program seems otherwise there - would be no hint on the string which is expected to be - returned. - - * all STRING arguments should be written in the same language. - - It is somewhat uncomfortable to write a program using the `catgets' -functions if no supporting functionality is available. Since each -set/message number tuple must be unique the programmer must keep lists -of the messages at the same time the code is written. And the work -between several people working on the same project must be coordinated. -We will see some how these problems can be relaxed a bit (*note Common -Usage::). - - - Function: int catclose (nl_catd CATALOG_DESC) - The `catclose' function can be used to free the resources - associated with a message catalog which previously was opened by a - call to `catopen'. If the resources can be successfully freed the - function returns `0'. Otherwise it return `-1' and the global - variable ERRNO is set. Errors can occur if the catalog descriptor - CATALOG_DESC is not valid in which case ERRNO is set to `EBADF'. - - -File: libc.info, Node: The message catalog files, Next: The gencat program, Prev: The catgets Functions, Up: Message catalogs a la X/Open - -Format of the message catalog files ------------------------------------ - - The only reasonable way the translate all the messages of a function -and store the result in a message catalog file which can be read by the -`catopen' function is to write all the message text to the translator -and let her/him translate them all. I.e., we must have a file with -entries which associate the set/message tuple with a specific -translation. This file format is specified in the X/Open standard and -is as follows: - - * Lines containing only whitespace characters or empty lines are - ignored. - - * Lines which contain as the first non-whitespace character a `$' - followed by a whitespace character are comment and are also - ignored. - - * If a line contains as the first non-whitespace characters the - sequence `$set' followed by a whitespace character an additional - argument is required to follow. This argument can either be: - - - a number. In this case the value of this number determines - the set to which the following messages are added. - - - an identifier consisting of alphanumeric characters plus the - underscore character. In this case the set get automatically - a number assigned. This value is one added to the largest - set number which so far appeared. - - How to use the symbolic names is explained in section *Note - Common Usage::. - - It is an error if a symbol name appears more than once. All - following messages are placed in a set with this number. - - * If a line contains as the first non-whitespace characters the - sequence `$delset' followed by a whitespace character an - additional argument is required to follow. This argument can - either be: - - - a number. In this case the value of this number determines - the set which will be deleted. - - - an identifier consisting of alphanumeric characters plus the - underscore character. This symbolic identifier must match a - name for a set which previously was defined. It is an error - if the name is unknown. - - In both cases all messages in the specified set will be removed. - They will not appear in the output. But if this set is later - again selected with a `$set' command again messages could be added - and these messages will appear in the output. - - * If a line contains after leading whitespaces the sequence - `$quote', the quoting character used for this input file is - changed to the first non-whitespace character following the - `$quote'. If no non-whitespace character is present before the - line ends quoting is disable. - - By default no quoting character is used. In this mode strings are - terminated with the first unescaped line break. If there is a - `$quote' sequence present newline need not be escaped. Instead a - string is terminated with the first unescaped appearance of the - quote character. - - A common usage of this feature would be to set the quote character - to `"'. Then any appearance of the `"' in the strings must be - escaped using the backslash (i.e., `\"' must be written). - - * Any other line must start with a number or an alphanumeric - identifier (with the underscore character included). The - following characters (starting after the first whitespace - character) will form the string which gets associated with the - currently selected set and the message number represented by the - number and identifier respectively. - - If the start of the line is a number the message number is - obvious. It is an error if the same message number already - appeared for this set. - - If the leading token was an identifier the message number gets - automatically assigned. The value is the current maximum messages - number for this set plus one. It is an error if the identifier was - already used for a message in this set. It is OK to reuse the - identifier for a message in another thread. How to use the - symbolic identifiers will be explained below (*note Common - Usage::). There is one limitation with the identifier: it must - not be `Set'. The reason will be explained below. - - The text of the messages can contain escape characters. The usual - bunch of characters known from the ISO C language are recognized - (`\n', `\t', `\v', `\b', `\r', `\f', `\\', and `\NNN', where NNN - is the octal coding of a character code). - - *Important:* The handling of identifiers instead of numbers for the -set and messages is a GNU extension. Systems strictly following the -X/Open specification do not have this feature. An example for a message -catalog file is this: - - $ This is a leading comment. - $quote " - - $set SetOne - 1 Message with ID 1. - two " Message with ID \"two\", which gets the value 2 assigned" - - $set SetTwo - $ Since the last set got the number 1 assigned this set has number 2. - 4000 "The numbers can be arbitrary, they need not start at one." - - This small example shows various aspects: - * Lines 1 and 9 are comments since they start with `$' followed by a - whitespace. - - * The quoting character is set to `"'. Otherwise the quotes in the - message definition would have to be left away and in this case the - message with the identifier `two' would loose its leading - whitespace. - - * Mixing numbered messages with message having symbolic names is no - problem and the numbering happens automatically. - - While this file format is pretty easy it is not the best possible for -use in a running program. The `catopen' function would have to parser -the file and handle syntactic errors gracefully. This is not so easy -and the whole process is pretty slow. Therefore the `catgets' -functions expect the data in another more compact and ready-to-use file -format. There is a special program `gencat' which is explained in -detail in the next section. - - Files in this other format are not human readable. To be easy to -use by programs it is a binary file. But the format is byte order -independent so translation files can be shared by systems of arbitrary -architecture (as long as they use the GNU C Library). - - Details about the binary file format are not important to know since -these files are always created by the `gencat' program. The sources of -the GNU C Library also provide the sources for the `gencat' program and -so the interested reader can look through these source files to learn -about the file format. - - -File: libc.info, Node: The gencat program, Next: Common Usage, Prev: The message catalog files, Up: Message catalogs a la X/Open - -Generate Message Catalogs files -------------------------------- - - The `gencat' program is specified in the X/Open standard and the GNU -implementation follows this specification and so processes all -correctly formed input files. Additionally some extension are -implemented which help to work in a more reasonable way with the -`catgets' functions. - - The `gencat' program can be invoked in two ways: - - `gencat [OPTION]... [OUTPUT-FILE [INPUT-FILE]...]` - - This is the interface defined in the X/Open standard. If no -INPUT-FILE parameter is given input will be read from standard input. -Multiple input files will be read as if they are concatenated. If -OUTPUT-FILE is also missing, the output will be written to standard -output. To provide the interface one is used to from other programs a -second interface is provided. - - `gencat [OPTION]... -o OUTPUT-FILE [INPUT-FILE]...` - - The option `-o' is used to specify the output file and all file -arguments are used as input files. - - Beside this one can use `-' or `/dev/stdin' for INPUT-FILE to denote -the standard input. Corresponding one can use `-' and `/dev/stdout' -for OUTPUT-FILE to denote standard output. Using `-' as a file name is -allowed in X/Open while using the device names is a GNU extension. - - The `gencat' program works by concatenating all input files and then -*merge* the resulting collection of message sets with a possibly -existing output file. This is done by removing all messages with -set/message number tuples matching any of the generated messages from -the output file and then adding all the new messages. To regenerate a -catalog file while ignoring the old contents therefore requires to -remove the output file if it exists. If the output is written to -standard output no merging takes place. - -The following table shows the options understood by the `gencat' -program. The X/Open standard does not specify any option for the -program so all of these are GNU extensions. - -`-V' -`--version' - Print the version information and exit. - -`-h' -`--help' - Print a usage message listing all available options, then exit - successfully. - -`--new' - Do never merge the new messages from the input files with the old - content of the output files. The old content of the output file - is discarded. - -`-H' -`--header=name' - This option is used to emit the symbolic names given to sets and - messages in the input files for use in the program. Details about - how to use this are given in the next section. The NAME parameter - to this option specifies the name of the output file. It will - contain a number of C preprocessor `#define's to associate a name - with a number. - - Please note that the generated file only contains the symbols from - the input files. If the output is merged with the previous - content of the output file the possibly existing symbols from the - file(s) which generated the old output files are not in the - generated header file. - - -File: libc.info, Node: Common Usage, Prev: The gencat program, Up: Message catalogs a la X/Open - -How to use the `catgets' interface ----------------------------------- - - The `catgets' functions can be used in two different ways. By -following slavishly the X/Open specs and not relying on the extension -and by using the GNU extensions. We will take a look at the former -method first to understand the benefits of extensions. - -Not using symbolic names -........................ - - Since the X/Open format of the message catalog files does not allow -symbol names we have to work with numbers all the time. When we start -writing a program we have to replace all appearances of translatable -strings with something like - - catgets (catdesc, set, msg, "string") - -CATGETS is retrieved from a call to `catopen' which is normally done -once at the program start. The `"string"' is the string we want to -translate. The problems start with the set and message numbers. - - In a bigger program several programmers usually work at the same -time on the program and so coordinating the number allocation is -crucial. Though no two different strings must be indexed by the same -tuple of numbers it is highly desirable to reuse the numbers for equal -strings with equal translations (please note that there might be -strings which are equal in one language but have different translations -due to difference contexts). - - The allocation process can be relaxed a bit by different set numbers -for different parts of the program. So the number of developers who -have to coordinate the allocation can be reduced. But still lists must -be keep track of the allocation and errors can easily happen. These -errors cannot be discovered by the compiler or the `catgets' functions. -Only the user of the program might see wrong messages printed. In the -worst cases the messages are so irritating that they cannot be -recognized as wrong. Think about the translations for `"true"' and -`"false"' being exchanged. This could result in a disaster. - -Using symbolic names -.................... - - The problems mentioned in the last section derive from the fact that: - - 1. the numbers are allocated once and due to the possibly frequent - use of them it is difficult to change a number later. - - 2. the numbers do not allow to guess anything about the string and - therefore collisions can easily happen. - - By constantly using symbolic names and by providing a method which -maps the string content to a symbolic name (however this will happen) -one can prevent both problems above. The cost of this is that the -programmer has to write a complete message catalog file while s/he is -writing the program itself. - - This is necessary since the symbolic names must be mapped to numbers -before the program sources can be compiled. In the last section it was -described how to generate a header containing the mapping of the names. -E.g., for the example message file given in the last section we could -call the `gencat' program as follow (assume `ex.msg' contains the -sources). - - gencat -H ex.h -o ex.cat ex.msg - -This generates a header file with the following content: - - #define SetTwoSet 0x2 /* ex.msg:8 */ - - #define SetOneSet 0x1 /* ex.msg:4 */ - #define SetOnetwo 0x2 /* ex.msg:6 */ - - As can be seen the various symbols given in the source file are -mangled to generate unique identifiers and these identifiers get numbers -assigned. Reading the source file and knowing about the rules will -allow to predict the content of the header file (it is deterministic) -but this is not necessary. The `gencat' program can take care for -everything. All the programmer has to do is to put the generated header -file in the dependency list of the source files of her/his project and -to add a rules to regenerate the header of any of the input files -change. - - One word about the symbol mangling. Every symbol consists of two -parts: the name of the message set plus the name of the message or the -special string `Set'. So `SetOnetwo' means this macro can be used to -access the translation with identifier `two' in the message set -`SetOne'. - - The other names denote the names of the message sets. The special -string `Set' is used in the place of the message identifier. - - If in the code the second string of the set `SetOne' is used the C -code should look like this: - - catgets (catdesc, SetOneSet, SetOnetwo, - " Message with ID \"two\", which gets the value 2 assigned") - - Writing the function this way will allow to change the message number -and even the set number without requiring any change in the C source -code. (The text of the string is normally not the same; this is only -for this example.) - -How does to this allow to develop -................................. - - To illustrate the usual way to work with the symbolic version numbers -here is a little example. Assume we want to write the very complex and -famous greeting program. We start by writing the code as usual: - - #include - int - main (void) - { - printf ("Hello, world!\n"); - return 0; - } - - Now we want to internationalize the message and therefore replace the -message with whatever the user wants. - - #include - #include - #include "msgnrs.h" - int - main (void) - { - nl_catd catdesc = catopen ("hello.cat", NL_CAT_LOCALE); - printf (catgets (catdesc, SetMainSet, SetMainHello, - "Hello, world!\n")); - catclose (catdesc); - return 0; - } - - We see how the catalog object is opened and the returned descriptor -used in the other function calls. It is not really necessary to check -for failure of any of the functions since even in these situations the -functions will behave reasonable. They simply will be return a -translation. - - What remains unspecified here are the constants `SetMainSet' and -`SetMainHello'. These are the symbolic names describing the message. -To get the actual definitions which match the information in the -catalog file we have to create the message catalog source file and -process it using the `gencat' program. - - $ Messages for the famous greeting program. - $quote " - - $set Main - Hello "Hallo, Welt!\n" - - Now we can start building the program (assume the message catalog -source file is named `hello.msg' and the program source file `hello.c'): - - % gencat -H msgnrs.h -o hello.cat hello.msg - % cat msgnrs.h - #define MainSet 0x1 /* hello.msg:4 */ - #define MainHello 0x1 /* hello.msg:5 */ - % gcc -o hello hello.c -I. - % cp hello.cat /usr/share/locale/de/LC_MESSAGES - % echo $LC_ALL - de - % ./hello - Hallo, Welt! - % - - The call of the `gencat' program creates the missing header file -`msgnrs.h' as well as the message catalog binary. The former is used -in the compilation of `hello.c' while the later is placed in a -directory in which the `catopen' function will try to locate it. -Please check the `LC_ALL' environment variable and the default path for -`catopen' presented in the description above. - - -File: libc.info, Node: The Uniforum approach, Prev: Message catalogs a la X/Open, Up: Message Translation - -The Uniforum approach to Message Translation -============================================ - - Sun Microsystems tried to standardize a different approach to message -translation in the Uniforum group. There never was a real standard -defined but still the interface was used in Sun's operation systems. -Since this approach fits better in the development process of free -software it is also used throughout the GNU project and the GNU -`gettext' package provides support for this outside the GNU C Library. - - The code of the `libintl' from GNU `gettext' is the same as the code -in the GNU C Library. So the documentation in the GNU `gettext' manual -is also valid for the functionality here. The following text will -describe the library functions in detail. But the numerous helper -programs are not described in this manual. Instead people should read -the GNU `gettext' manual (*note GNU gettext utilities: (gettext)Top.). -We will only give a short overview. - - Though the `catgets' functions are available by default on more -systems the `gettext' interface is at least as portable as the former. -The GNU `gettext' package can be used wherever the functions are not -available. - -* Menu: - -* Message catalogs with gettext:: The `gettext' family of functions. -* Helper programs for gettext:: Programs to handle message catalogs - for `gettext'. - - -File: libc.info, Node: Message catalogs with gettext, Next: Helper programs for gettext, Up: The Uniforum approach - -The `gettext' family of functions ---------------------------------- - - The paradigms underlying the `gettext' approach to message -translations is different from that of the `catgets' functions the -basic functionally is equivalent. There are functions of the following -categories: - -* Menu: - -* Translation with gettext:: What has to be done to translate a message. -* Locating gettext catalog:: How to determine which catalog to be used. -* Advanced gettext functions:: Additional functions for more complicated - situations. -* Charset conversion in gettext:: How to specify the output character set - `gettext' uses. -* GUI program problems:: How to use `gettext' in GUI programs. -* Using gettextized software:: The possibilities of the user to influence - the way `gettext' works. - - -File: libc.info, Node: Translation with gettext, Next: Locating gettext catalog, Up: Message catalogs with gettext - -What has to be done to translate a message? -........................................... - - The `gettext' functions have a very simple interface. The most -basic function just takes the string which shall be translated as the -argument and it returns the translation. This is fundamentally -different from the `catgets' approach where an extra key is necessary -and the original string is only used for the error case. - - If the string which has to be translated is the only argument this of -course means the string itself is the key. I.e., the translation will -be selected based on the original string. The message catalogs must -therefore contain the original strings plus one translation for any such -string. The task of the `gettext' function is it to compare the -argument string with the available strings in the catalog and return the -appropriate translation. Of course this process is optimized so that -this process is not more expensive than an access using an atomic key -like in `catgets'. - - The `gettext' approach has some advantages but also some -disadvantages. Please see the GNU `gettext' manual for a detailed -discussion of the pros and cons. - - All the definitions and declarations for `gettext' can be found in -the `libintl.h' header file. On systems where these functions are not -part of the C library they can be found in a separate library named -`libintl.a' (or accordingly different for shared libraries). - - - Function: char * gettext (const char *MSGID) - The `gettext' function searches the currently selected message - catalogs for a string which is equal to MSGID. If there is such a - string available it is returned. Otherwise the argument string - MSGID is returned. - - Please note that all though the return value is `char *' the - returned string must not be changed. This broken type results - from the history of the function and does not reflect the way the - function should be used. - - Please note that above we wrote "message catalogs" (plural). This - is a specialty of the GNU implementation of these functions and we - will say more about this when we talk about the ways message - catalogs are selected (*note Locating gettext catalog::). - - The `gettext' function does not modify the value of the global - ERRNO variable. This is necessary to make it possible to write - something like - - printf (gettext ("Operation failed: %m\n")); - - Here the ERRNO value is used in the `printf' function while - processing the `%m' format element and if the `gettext' function - would change this value (it is called before `printf' is called) - we would get a wrong message. - - So there is no easy way to detect a missing message catalog beside - comparing the argument string with the result. But it is normally - the task of the user to react on missing catalogs. The program - cannot guess when a message catalog is really necessary since for - a user who speaks the language the program was developed in does - not need any translation. - - The remaining two functions to access the message catalog add some -functionality to select a message catalog which is not the default one. -This is important if parts of the program are developed independently. -Every part can have its own message catalog and all of them can be used -at the same time. The C library itself is an example: internally it -uses the `gettext' functions but since it must not depend on a -currently selected default message catalog it must specify all ambiguous -information. - - - Function: char * dgettext (const char *DOMAINNAME, const char *MSGID) - The `dgettext' functions acts just like the `gettext' function. - It only takes an additional first argument DOMAINNAME which guides - the selection of the message catalogs which are searched for the - translation. If the DOMAINNAME parameter is the null pointer the - `dgettext' function is exactly equivalent to `gettext' since the - default value for the domain name is used. - - As for `gettext' the return value type is `char *' which is an - anachronism. The returned string must never be modified. - - - Function: char * dcgettext (const char *DOMAINNAME, const char - *MSGID, int CATEGORY) - The `dcgettext' adds another argument to those which `dgettext' - takes. This argument CATEGORY specifies the last piece of - information needed to localize the message catalog. I.e., the - domain name and the locale category exactly specify which message - catalog has to be used (relative to a given directory, see below). - - The `dgettext' function can be expressed in terms of `dcgettext' - by using - - dcgettext (domain, string, LC_MESSAGES) - - instead of - - dgettext (domain, string) - - This also shows which values are expected for the third parameter. - One has to use the available selectors for the categories - available in `locale.h'. Normally the available values are - `LC_CTYPE', `LC_COLLATE', `LC_MESSAGES', `LC_MONETARY', - `LC_NUMERIC', and `LC_TIME'. Please note that `LC_ALL' must not - be used and even though the names might suggest this, there is no - relation to the environments variables of this name. - - The `dcgettext' function is only implemented for compatibility with - other systems which have `gettext' functions. There is not really - any situation where it is necessary (or useful) to use a different - value but `LC_MESSAGES' in for the CATEGORY parameter. We are - dealing with messages here and any other choice can only be - irritating. - - As for `gettext' the return value type is `char *' which is an - anachronism. The returned string must never be modified. - - When using the three functions above in a program it is a frequent -case that the MSGID argument is a constant string. So it is worth to -optimize this case. Thinking shortly about this one will realize that -as long as no new message catalog is loaded the translation of a message -will not change. This optimization is actually implemented by the -`gettext', `dgettext' and `dcgettext' functions. - - -File: libc.info, Node: Locating gettext catalog, Next: Advanced gettext functions, Prev: Translation with gettext, Up: Message catalogs with gettext - -How to determine which catalog to be used -......................................... - - The functions to retrieve the translations for a given message have a -remarkable simple interface. But to provide the user of the program -still the opportunity to select exactly the translation s/he wants and -also to provide the programmer the possibility to influence the way to -locate the search for catalogs files there is a quite complicated -underlying mechanism which controls all this. The code is complicated -the use is easy. - - Basically we have two different tasks to perform which can also be -performed by the `catgets' functions: - - 1. Locate the set of message catalogs. There are a number of files - for different languages and which all belong to the package. - Usually they are all stored in the filesystem below a certain - directory. - - There can be arbitrary many packages installed and they can follow - different guidelines for the placement of their files. - - 2. Relative to the location specified by the package the actual - translation files must be searched, based on the wishes of the - user. I.e., for each language the user selects the program should - be able to locate the appropriate file. - - This is the functionality required by the specifications for -`gettext' and this is also what the `catgets' functions are able to do. -But there are some problems unresolved: - - * The language to be used can be specified in several different ways. - There is no generally accepted standard for this and the user - always expects the program understand what s/he means. E.g., to - select the German translation one could write `de', `german', or - `deutsch' and the program should always react the same. - - * Sometimes the specification of the user is too detailed. If s/he, - e.g., specifies `de_DE.ISO-8859-1' which means German, spoken in - Germany, coded using the ISO 8859-1 character set there is the - possibility that a message catalog matching this exactly is not - available. But there could be a catalog matching `de' and if the - character set used on the machine is always ISO 8859-1 there is no - reason why this later message catalog should not be used. (We - call this "message inheritance".) - - * If a catalog for a wanted language is not available it is not - always the second best choice to fall back on the language of the - developer and simply not translate any message. Instead a user - might be better able to read the messages in another language and - so the user of the program should be able to define an precedence - order of languages. - - We can divide the configuration actions in two parts: the one is -performed by the programmer, the other by the user. We will start with -the functions the programmer can use since the user configuration will -be based on this. - - As the functions described in the last sections already mention -separate sets of messages can be selected by a "domain name". This is a -simple string which should be unique for each program part with uses a -separate domain. It is possible to use in one program arbitrary many -domains at the same time. E.g., the GNU C Library itself uses a domain -named `libc' while the program using the C Library could use a domain -named `foo'. The important point is that at any time exactly one -domain is active. This is controlled with the following function. - - - Function: char * textdomain (const char *DOMAINNAME) - The `textdomain' function sets the default domain, which is used in - all future `gettext' calls, to DOMAINNAME. Please note that - `dgettext' and `dcgettext' calls are not influenced if the - DOMAINNAME parameter of these functions is not the null pointer. - - Before the first call to `textdomain' the default domain is - `messages'. This is the name specified in the specification of - the `gettext' API. This name is as good as any other name. No - program should ever really use a domain with this name since this - can only lead to problems. - - The function returns the value which is from now on taken as the - default domain. If the system went out of memory the returned - value is `NULL' and the global variable ERRNO is set to `ENOMEM'. - Despite the return value type being `char *' the return string must - not be changed. It is allocated internally by the `textdomain' - function. - - If the DOMAINNAME parameter is the null pointer no new default - domain is set. Instead the currently selected default domain is - returned. - - If the DOMAINNAME parameter is the empty string the default domain - is reset to its initial value, the domain with the name `messages'. - This possibility is questionable to use since the domain `messages' - really never should be used. - - - Function: char * bindtextdomain (const char *DOMAINNAME, const char - *DIRNAME) - The `bindtextdomain' function can be used to specify the directory - which contains the message catalogs for domain DOMAINNAME for the - different languages. To be correct, this is the directory where - the hierarchy of directories is expected. Details are explained - below. - - For the programmer it is important to note that the translations - which come with the program have be placed in a directory - hierarchy starting at, say, `/foo/bar'. Then the program should - make a `bindtextdomain' call to bind the domain for the current - program to this directory. So it is made sure the catalogs are - found. A correctly running program does not depend on the user - setting an environment variable. - - The `bindtextdomain' function can be used several times and if the - DOMAINNAME argument is different the previously bound domains will - not be overwritten. - - If the program which wish to use `bindtextdomain' at some point of - time use the `chdir' function to change the current working - directory it is important that the DIRNAME strings ought to be an - absolute pathname. Otherwise the addressed directory might vary - with the time. - - If the DIRNAME parameter is the null pointer `bindtextdomain' - returns the currently selected directory for the domain with the - name DOMAINNAME. - - The `bindtextdomain' function returns a pointer to a string - containing the name of the selected directory name. The string is - allocated internally in the function and must not be changed by the - user. If the system went out of core during the execution of - `bindtextdomain' the return value is `NULL' and the global - variable ERRNO is set accordingly. - diff -u -udbrN glibc-2.3.2/manual/libc.info-14 glibc-2.3.2-200304020432/manual/libc.info-14 --- glibc-2.3.2/manual/libc.info-14 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-14 Thu Jan 1 01:00:00 1970 @@ -1,1159 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

What is -meant here is the handling of plural forms. - - Looking through Unix source code before the time anybody thought -about internationalization (and, sadly, even afterwards) one can often -find code similar to the following: - - printf ("%d file%s deleted", n, n == 1 ? "" : "s"); - -After the first complaints from people internationalizing the code -people either completely avoided formulations like this or used strings -like `"file(s)"'. Both look unnatural and should be avoided. First -tries to solve the problem correctly looked like this: - - if (n == 1) - printf ("%d file deleted", n); - else - printf ("%d files deleted", n); - - But this does not solve the problem. It helps languages where the -plural form of a noun is not simply constructed by adding an `s' but -that is all. Once again people fell into the trap of believing the -rules their language is using are universal. But the handling of plural -forms differs widely between the language families. There are two -things we can differ between (and even inside language families); - - * The form how plural forms are build differs. This is a problem - with language which have many irregularities. German, for - instance, is a drastic case. Though English and German are part - of the same language family (Germanic), the almost regular forming - of plural noun forms (appending an `s') is hardly found in German. - - * The number of plural forms differ. This is somewhat surprising for - those who only have experiences with Romanic and Germanic languages - since here the number is the same (there are two). - - But other language families have only one form or many forms. More - information on this in an extra section. - - The consequence of this is that application writers should not try to -solve the problem in their code. This would be localization since it is -only usable for certain, hardcoded language environments. Instead the -extended `gettext' interface should be used. - - These extra functions are taking instead of the one key string two -strings and an numerical argument. The idea behind this is that using -the numerical argument and the first string as a key, the implementation -can select using rules specified by the translator the right plural -form. The two string arguments then will be used to provide a return -value in case no message catalog is found (similar to the normal -`gettext' behavior). In this case the rules for Germanic language is -used and it is assumed that the first string argument is the singular -form, the second the plural form. - - This has the consequence that programs without language catalogs can -display the correct strings only if the program itself is written using -a Germanic language. This is a limitation but since the GNU C library -(as well as the GNU `gettext' package) are written as part of the GNU -package and the coding standards for the GNU project require program -being written in English, this solution nevertheless fulfills its -purpose. - - - Function: char * ngettext (const char *MSGID1, const char *MSGID2, - unsigned long int N) - The `ngettext' function is similar to the `gettext' function as it - finds the message catalogs in the same way. But it takes two - extra arguments. The MSGID1 parameter must contain the singular - form of the string to be converted. It is also used as the key - for the search in the catalog. The MSGID2 parameter is the plural - form. The parameter N is used to determine the plural form. If no - message catalog is found MSGID1 is returned if `n == 1', otherwise - `msgid2'. - - An example for the us of this function is: - - printf (ngettext ("%d file removed", "%d files removed", n), n); - - Please note that the numeric value N has to be passed to the - `printf' function as well. It is not sufficient to pass it only to - `ngettext'. - - - Function: char * dngettext (const char *DOMAIN, const char *MSGID1, - const char *MSGID2, unsigned long int N) - The `dngettext' is similar to the `dgettext' function in the way - the message catalog is selected. The difference is that it takes - two extra parameter to provide the correct plural form. These two - parameters are handled in the same way `ngettext' handles them. - - - Function: char * dcngettext (const char *DOMAIN, const char *MSGID1, - const char *MSGID2, unsigned long int N, int CATEGORY) - The `dcngettext' is similar to the `dcgettext' function in the way - the message catalog is selected. The difference is that it takes - two extra parameter to provide the correct plural form. These two - parameters are handled in the same way `ngettext' handles them. - -The problem of plural forms -........................... - - A description of the problem can be found at the beginning of the -last section. Now there is the question how to solve it. Without the -input of linguists (which was not available) it was not possible to -determine whether there are only a few different forms in which plural -forms are formed or whether the number can increase with every new -supported language. - - Therefore the solution implemented is to allow the translator to -specify the rules of how to select the plural form. Since the formula -varies with every language this is the only viable solution except for -hardcoding the information in the code (which still would require the -possibility of extensions to not prevent the use of new languages). The -details are explained in the GNU `gettext' manual. Here only a a bit -of information is provided. - - The information about the plural form selection has to be stored in -the header entry (the one with the empty (`msgid' string). It looks -like this: - - Plural-Forms: nplurals=2; plural=n == 1 ? 0 : 1; - - The `nplurals' value must be a decimal number which specifies how -many different plural forms exist for this language. The string -following `plural' is an expression which is using the C language -syntax. Exceptions are that no negative number are allowed, numbers -must be decimal, and the only variable allowed is `n'. This expression -will be evaluated whenever one of the functions `ngettext', -`dngettext', or `dcngettext' is called. The numeric value passed to -these functions is then substituted for all uses of the variable `n' in -the expression. The resulting value then must be greater or equal to -zero and smaller than the value given as the value of `nplurals'. - -The following rules are known at this point. The language with families -are listed. But this does not necessarily mean the information can be -generalized for the whole family (as can be easily seen in the table -below).(1) - -Only one form: - Some languages only require one single form. There is no - distinction between the singular and plural form. An appropriate - header entry would look like this: - - Plural-Forms: nplurals=1; plural=0; - - Languages with this property include: - - Finno-Ugric family - Hungarian - - Asian family - Japanese - - Turkic/Altaic family - Turkish - -Two forms, singular used for one only - This is the form used in most existing programs since it is what - English is using.

It -also converts the translation on the fly to the desired output character -set. This is useful if the user is working in a different character set -than the translator who created the message catalog, because it avoids -distributing variants of message catalogs which differ only in the -character set. - - The output character set is, by default, the value of `nl_langinfo -(CODESET)', which depends on the `LC_CTYPE' part of the current locale. -But programs which store strings in a locale independent way (e.g. -UTF-8) can request that `gettext' and related functions return the -translations in that encoding, by use of the `bind_textdomain_codeset' -function. - - Note that the MSGID argument to `gettext' is not subject to -character set conversion. Also, when `gettext' does not find a -translation for MSGID, it returns MSGID unchanged - independently of -the current output character set. It is therefore recommended that all -MSGIDs be US-ASCII strings. - - - Function: char * bind_textdomain_codeset (const char *DOMAINNAME, - const char *CODESET) - The `bind_textdomain_codeset' function can be used to specify the - output character set for message catalogs for domain DOMAINNAME. - The CODESET argument must be a valid codeset name which can be used - for the `iconv_open' function, or a null pointer. - - If the CODESET parameter is the null pointer, - `bind_textdomain_codeset' returns the currently selected codeset - for the domain with the name DOMAINNAME. It returns `NULL' if no - codeset has yet been selected. - - The `bind_textdomain_codeset' function can be used several times. - If used multiple times with the same DOMAINNAME argument, the - later call overrides the settings made by the earlier one. - - The `bind_textdomain_codeset' function returns a pointer to a - string containing the name of the selected codeset. The string is - allocated internally in the function and must not be changed by the - user. If the system went out of core during the execution of - `bind_textdomain_codeset', the return value is `NULL' and the - global variable ERRNO is set accordingly. - - -File: libc.info, Node: GUI program problems, Next: Using gettextized software, Prev: Charset conversion in gettext, Up: Message catalogs with gettext - -How to use `gettext' in GUI programs -.................................... - - One place where the `gettext' functions, if used normally, have big -problems is within programs with graphical user interfaces (GUIs). The -problem is that many of the strings which have to be translated are very -short. They have to appear in pull-down menus which restricts the -length. But strings which are not containing entire sentences or at -least large fragments of a sentence may appear in more than one -situation in the program but might have different translations. This is -especially true for the one-word strings which are frequently used in -GUI programs. - - As a consequence many people say that the `gettext' approach is -wrong and instead `catgets' should be used which indeed does not have -this problem. But there is a very simple and powerful method to handle -these kind of problems with the `gettext' functions. - -As as example consider the following fictional situation. A GUI program -has a menu bar with the following entries: - - +------------+------------+--------------------------------------+ - | File | Printer | | - +------------+------------+--------------------------------------+ - | Open | | Select | - | New | | Open | - +----------+ | Connect | - +----------+ - - To have the strings `File', `Printer', `Open', `New', `Select', and -`Connect' translated there has to be at some point in the code a call -to a function of the `gettext' family. But in two places the string -passed into the function would be `Open'. The translations might not -be the same and therefore we are in the dilemma described above. - - One solution to this problem is to artificially enlengthen the -strings to make them unambiguous. But what would the program do if no -translation is available? The enlengthened string is not what should be -printed. So we should use a little bit modified version of the -functions. - - To enlengthen the strings a uniform method should be used. E.g., in -the example above the strings could be chosen as - - Menu|File - Menu|Printer - Menu|File|Open - Menu|File|New - Menu|Printer|Select - Menu|Printer|Open - Menu|Printer|Connect - - Now all the strings are different and if now instead of `gettext' -the following little wrapper function is used, everything works just -fine: - - char * - sgettext (const char *msgid) - { - char *msgval = gettext (msgid); - if (msgval == msgid) - msgval = strrchr (msgid, '|') + 1; - return msgval; - } - - What this little function does is to recognize the case when no -translation is available. This can be done very efficiently by a -pointer comparison since the return value is the input value. If there -is no translation we know that the input string is in the format we used -for the Menu entries and therefore contains a `|' character. We simply -search for the last occurrence of this character and return a pointer -to the character following it. That's it! - - If one now consistently uses the enlengthened string form and -replaces the `gettext' calls with calls to `sgettext' (this is normally -limited to very few places in the GUI implementation) then it is -possible to produce a program which can be internationalized. - - With advanced compilers (such as GNU C) one can write the `sgettext' -functions as an inline function or as a macro like this: - - #define sgettext(msgid) \ - ({ const char *__msgid = (msgid); \ - char *__msgstr = gettext (__msgid); \ - if (__msgval == __msgid) \ - __msgval = strrchr (__msgid, '|') + 1; \ - __msgval; }) - - The other `gettext' functions (`dgettext', `dcgettext' and the -`ngettext' equivalents) can and should have corresponding functions as -well which look almost identical, except for the parameters and the -call to the underlying function. - - Now there is of course the question why such functions do not exist -in the GNU C library? There are two parts of the answer to this -question. - - * They are easy to write and therefore can be provided by the - project they are used in. This is not an answer by itself and - must be seen together with the second part which is: - - * There is no way the C library can contain a version which can work - everywhere. The problem is the selection of the character to - separate the prefix from the actual string in the enlenghtened - string. The examples above used `|' which is a quite good choice - because it resembles a notation frequently used in this context - and it also is a character not often used in message strings. - - But what if the character is used in message strings. Or if the - chose character is not available in the character set on the - machine one compiles (e.g., `|' is not required to exist for - ISO C; this is why the `iso646.h' file exists in ISO C programming - environments). - - There is only one more comment to make left. The wrapper function -above require that the translations strings are not enlengthened -themselves. This is only logical. There is no need to disambiguate -the strings (since they are never used as keys for a search) and one -also saves quite some memory and disk space by doing this. - - -File: libc.info, Node: Using gettextized software, Prev: GUI program problems, Up: Message catalogs with gettext - -User influence on `gettext' -........................... - - The last sections described what the programmer can do to -internationalize the messages of the program. But it is finally up to -the user to select the message s/he wants to see. S/He must understand -them. - - The POSIX locale model uses the environment variables `LC_COLLATE', -`LC_CTYPE', `LC_MESSAGES', `LC_MONETARY', `NUMERIC', and `LC_TIME' to -select the locale which is to be used. This way the user can influence -lots of functions. As we mentioned above the `gettext' functions also -take advantage of this. - - To understand how this happens it is necessary to take a look at the -various components of the filename which gets computed to locate a -message catalog. It is composed as follows: - - DIR_NAME/LOCALE/LC_CATEGORY/DOMAIN_NAME.mo - - The default value for DIR_NAME is system specific. It is computed -from the value given as the prefix while configuring the C library. -This value normally is `/usr' or `/'. For the former the complete -DIR_NAME is: - - /usr/share/locale - - We can use `/usr/share' since the `.mo' files containing the message -catalogs are system independent, so all systems can use the same files. -If the program executed the `bindtextdomain' function for the message -domain that is currently handled, the `dir_name' component is exactly -the value which was given to the function as the second parameter. -I.e., `bindtextdomain' allows overwriting the only system dependent and -fixed value to make it possible to address files anywhere in the -filesystem. - - The CATEGORY is the name of the locale category which was selected -in the program code. For `gettext' and `dgettext' this is always -`LC_MESSAGES', for `dcgettext' this is selected by the value of the -third parameter. As said above it should be avoided to ever use a -category other than `LC_MESSAGES'. - - The LOCALE component is computed based on the category used. Just -like for the `setlocale' function here comes the user selection into -the play. Some environment variables are examined in a fixed order and -the first environment variable set determines the return value of the -lookup process. In detail, for the category `LC_xxx' the following -variables in this order are examined: - -`LANGUAGE' - -`LC_ALL' - -`LC_xxx' - -`LANG' - This looks very familiar. With the exception of the `LANGUAGE' -environment variable this is exactly the lookup order the `setlocale' -function uses. But why introducing the `LANGUAGE' variable? - - The reason is that the syntax of the values these variables can have -is different to what is expected by the `setlocale' function. If we -would set `LC_ALL' to a value following the extended syntax that would -mean the `setlocale' function will never be able to use the value of -this variable as well. An additional variable removes this problem -plus we can select the language independently of the locale setting -which sometimes is useful. - - While for the `LC_xxx' variables the value should consist of exactly -one specification of a locale the `LANGUAGE' variable's value can -consist of a colon separated list of locale names. The attentive -reader will realize that this is the way we manage to implement one of -our additional demands above: we want to be able to specify an ordered -list of language. - - Back to the constructed filename we have only one component missing. -The DOMAIN_NAME part is the name which was either registered using the -`textdomain' function or which was given to `dgettext' or `dcgettext' -as the first parameter. Now it becomes obvious that a good choice for -the domain name in the program code is a string which is closely -related to the program/package name. E.g., for the GNU C Library the -domain name is `libc'. - -A limit piece of example code should show how the programmer is supposed -to work: - - { - setlocale (LC_ALL, ""); - textdomain ("test-package"); - bindtextdomain ("test-package", "/usr/local/share/locale"); - puts (gettext ("Hello, world!")); - } - - At the program start the default domain is `messages', and the -default locale is "C". The `setlocale' call sets the locale according -to the user's environment variables; remember that correct functioning -of `gettext' relies on the correct setting of the `LC_MESSAGES' locale -(for looking up the message catalog) and of the `LC_CTYPE' locale (for -the character set conversion). The `textdomain' call changes the -default domain to `test-package'. The `bindtextdomain' call specifies -that the message catalogs for the domain `test-package' can be found -below the directory `/usr/local/share/locale'. - - If now the user set in her/his environment the variable `LANGUAGE' -to `de' the `gettext' function will try to use the translations from -the file - - /usr/local/share/locale/de/LC_MESSAGES/test-package.mo - - From the above descriptions it should be clear which component of -this filename is determined by which source. - - In the above example we assumed that the `LANGUAGE' environment -variable to `de'. This might be an appropriate selection but what -happens if the user wants to use `LC_ALL' because of the wider -usability and here the required value is `de_DE.ISO-8859-1'? We -already mentioned above that a situation like this is not infrequent. -E.g., a person might prefer reading a dialect and if this is not -available fall back on the standard language. - - The `gettext' functions know about situations like this and can -handle them gracefully. The functions recognize the format of the value -of the environment variable. It can split the value is different pieces -and by leaving out the only or the other part it can construct new -values. This happens of course in a predictable way. To understand -this one must know the format of the environment variable value. There -is one more or less standardized form, originally from the X/Open -specification: - - `language[_territory[.codeset]][@modifier]' - - Less specific locale names will be stripped of in the order of the -following list: - - 1. `codeset' - - 2. `normalized codeset' - - 3. `territory' - - 4. `modifier' - - The `language' field will never be dropped for obvious reasons. - - The only new thing is the `normalized codeset' entry. This is -another goodie which is introduced to help reducing the chaos which -derives from the inability of the people to standardize the names of -character sets. Instead of ISO-8859-1 one can often see 8859-1, 88591, -iso8859-1, or iso_8859-1. The `normalized codeset' value is generated -from the user-provided character set name by applying the following -rules: - - 1. Remove all characters beside numbers and letters. - - 2. Fold letters to lowercase. - - 3. If the same only contains digits prepend the string `"iso"'. - -So all of the above name will be normalized to `iso88591'. This allows -the program user much more freely choosing the locale name. - - Even this extended functionality still does not help to solve the -problem that completely different names can be used to denote the same -locale (e.g., `de' and `german'). To be of help in this situation the -locale implementation and also the `gettext' functions know about -aliases. - - The file `/usr/share/locale/locale.alias' (replace `/usr' with -whatever prefix you used for configuring the C library) contains a -mapping of alternative names to more regular names. The system manager -is free to add new entries to fill her/his own needs. The selected -locale from the environment is compared with the entries in the first -column of this file ignoring the case. If they match the value of the -second column is used instead for the further handling. - - In the description of the format of the environment variables we -already mentioned the character set as a factor in the selection of the -message catalog. In fact, only catalogs which contain text written -using the character set of the system/program can be used (directly; -there will come a solution for this some day). This means for the user -that s/he will always have to take care for this. If in the collection -of the message catalogs there are files for the same language but coded -using different character sets the user has to be careful. - - -File: libc.info, Node: Helper programs for gettext, Prev: Message catalogs with gettext, Up: The Uniforum approach - -Programs to handle message catalogs for `gettext' -------------------------------------------------- - - The GNU C Library does not contain the source code for the programs -to handle message catalogs for the `gettext' functions.

The GNU C library contains -functions to perform linear search. The prototypes for the following -two functions can be found in `search.h'. - - - Function: void * lfind (const void *KEY, void *BASE, size_t *NMEMB, - size_t SIZE, comparison_fn_t COMPAR) - The `lfind' function searches in the array with `*NMEMB' elements - of SIZE bytes pointed to by BASE for an element which matches the - one pointed to by KEY. The function pointed to by COMPAR is used - decide whether two elements match. - - The return value is a pointer to the matching element in the array - starting at BASE if it is found. If no matching element is - available `NULL' is returned. - - The mean runtime of this function is `*NMEMB'/2. This function - should only be used elements often get added to or deleted from - the array in which case it might not be useful to sort the array - before searching. - - - Function: void * lsearch (const void *KEY, void *BASE, size_t - *NMEMB, size_t SIZE, comparison_fn_t COMPAR) - The `lsearch' function is similar to the `lfind' function. It - searches the given array for an element and returns it if found. - The difference is that if no matching element is found the - `lsearch' function adds the object pointed to by KEY (with a size - of SIZE bytes) at the end of the array and it increments the value - of `*NMEMB' to reflect this addition. - - This means for the caller that if it is not sure that the array - contains the element one is searching for the memory allocated for - the array starting at BASE must have room for at least SIZE more - bytes. If one is sure the element is in the array it is better to - use `lfind' so having more room in the array is always necessary - when calling `lsearch'. - - To search a sorted array for an element matching the key, use the -`bsearch' function. The prototype for this function is in the header -file `stdlib.h'. - - - Function: void * bsearch (const void *KEY, const void *ARRAY, size_t - COUNT, size_t SIZE, comparison_fn_t COMPARE) - The `bsearch' function searches the sorted array ARRAY for an - object that is equivalent to KEY.

There are other methods to organize -information which later should be searched. The costs of insert, -delete and search differ. One possible implementation is using hashing -tables. The following functions are declared in the the header file -`search.h'. - - - Function: int hcreate (size_t NEL) - The `hcreate' function creates a hashing table which can contain at - least NEL elements. There is no possibility to grow this table so - it is necessary to choose the value for NEL wisely. The used - methods to implement this function might make it necessary to make - the number of elements in the hashing table larger than the - expected maximal number of elements. Hashing tables usually work - inefficient if they are filled 80% or more. The constant access - time guaranteed by hashing can only be achieved if few collisions - exist. See Knuth's "The Art of Computer Programming, Part 3: - Searching and Sorting" for more information. - - The weakest aspect of this function is that there can be at most - one hashing table used through the whole program. The table is - allocated in local memory out of control of the programmer. As an - extension the GNU C library provides an additional set of - functions with an reentrant interface which provide a similar - interface but which allow to keep arbitrarily many hashing tables. - - It is possible to use more than one hashing table in the program - run if the former table is first destroyed by a call to `hdestroy'. - - The function returns a non-zero value if successful. If it return - zero something went wrong. This could either mean there is - already a hashing table in use or the program runs out of memory. - - - Function: void hdestroy (void) - The `hdestroy' function can be used to free all the resources - allocated in a previous call of `hcreate'. After a call to this - function it is again possible to call `hcreate' and allocate a new - table with possibly different size. - - It is important to remember that the elements contained in the - hashing table at the time `hdestroy' is called are _not_ freed by - this function. It is the responsibility of the program code to - free those strings (if necessary at all). Freeing all the element - memory is not possible without extra, separately kept information - since there is no function to iterate through all available - elements in the hashing table. If it is really necessary to free - a table and all elements the programmer has to keep a list of all - table elements and before calling `hdestroy' s/he has to free all - element's data using this list. This is a very unpleasant - mechanism and it also shows that this kind of hashing tables is - mainly meant for tables which are created once and used until the - end of the program run. - - Entries of the hashing table and keys for the search are defined -using this type: - - - Data type: struct ENTRY - Both elements of this structure are pointers to zero-terminated - strings. This is a limiting restriction of the functionality of - the `hsearch' functions. They can only be used for data sets - which use the NUL character always and solely to terminate the - records. It is not possible to handle general binary data. - - `char *key' - Pointer to a zero-terminated string of characters describing - the key for the search or the element in the hashing table. - - `char *data' - Pointer to a zero-terminated string of characters describing - the data. If the functions will be called only for searching - an existing entry this element might stay undefined since it - is not used. - - - Function: ENTRY * hsearch (ENTRY ITEM, ACTION ACTION) - To search in a hashing table created using `hcreate' the `hsearch' - function must be used. This function can perform simple search - for an element (if ACTION has the `FIND') or it can alternatively - insert the key element into the hashing table. Entries are never - replaced. - - The key is denoted by a pointer to an object of type `ENTRY'. For - locating the corresponding position in the hashing table only the - `key' element of the structure is used. - - If an entry with matching key is found the ACTION parameter is - irrelevant. The found entry is returned. If no matching entry is - found and the ACTION parameter has the value `FIND' the function - returns a `NULL' pointer. If no entry is found and the ACTION - parameter has the value `ENTER' a new entry is added to the - hashing table which is initialized with the parameter ITEM. A - pointer to the newly added entry is returned. - - As mentioned before the hashing table used by the functions -described so far is global and there can be at any time at most one -hashing table in the program. A solution is to use the following -functions which are a GNU extension. All have in common that they -operate on a hashing table which is described by the content of an -object of the type `struct hsearch_data'. This type should be treated -as opaque, none of its members should be changed directly. - - - Function: int hcreate_r (size_t NEL, struct hsearch_data *HTAB) - The `hcreate_r' function initializes the object pointed to by HTAB - to contain a hashing table with at least NEL elements. So this - function is equivalent to the `hcreate' function except that the - initialized data structure is controlled by the user. - - This allows having more than one hashing table at one time. The - memory necessary for the `struct hsearch_data' object can be - allocated dynamically. It must be initialized with zero before - calling this function. - - The return value is non-zero if the operation were successful. if - the return value is zero something went wrong which probably means - the programs runs out of memory. - - - Function: void hdestroy_r (struct hsearch_data *HTAB) - The `hdestroy_r' function frees all resources allocated by the - `hcreate_r' function for this very same object HTAB. As for - `hdestroy' it is the programs responsibility to free the strings - for the elements of the table. - - - Function: int hsearch_r (ENTRY ITEM, ACTION ACTION, ENTRY **RETVAL, - struct hsearch_data *HTAB) - The `hsearch_r' function is equivalent to `hsearch'. The meaning - of the first two arguments is identical. But instead of operating - on a single global hashing table the function works on the table - described by the object pointed to by HTAB (which is initialized - by a call to `hcreate_r'). - - Another difference to `hcreate' is that the pointer to the found - entry in the table is not the return value of the functions. It is - returned by storing it in a pointer variables pointed to by the - RETVAL parameter. The return value of the function is an integer - value indicating success if it is non-zero and failure if it is - zero. In the latter case the global variable ERRNO signals the - reason for the failure. - - `ENOMEM' - The table is filled and `hsearch_r' was called with an so far - unknown key and ACTION set to `ENTER'. - - `ESRCH' - The ACTION parameter is `FIND' and no corresponding element - is found in the table. - diff -u -udbrN glibc-2.3.2/manual/libc.info-15 glibc-2.3.2-200304020432/manual/libc.info-15 --- glibc-2.3.2/manual/libc.info-15 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-15 Thu Jan 1 01:00:00 1970 @@ -1,1197 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

The `tsearch' function family provides a nice interface to -functions to organize possibly large amounts of data by providing a mean -access time proportional to the logarithm of the number of elements. -The GNU C library implementation even guarantees that this bound is -never exceeded even for input data which cause problems for simple -binary tree implementations. - - The functions described in the chapter are all described in the -System V and X/Open specifications and are therefore quite portable. - - In contrast to the `hsearch' functions the `tsearch' functions can -be used with arbitrary data and not only zero-terminated strings. - - The `tsearch' functions have the advantage that no function to -initialize data structures is necessary. A simple pointer of type -`void *' initialized to `NULL' is a valid tree and can be extended or -searched. The prototypes for these functions can be found in the -header file `search.h'. - - - Function: void * tsearch (const void *KEY, void **ROOTP, - comparison_fn_t COMPAR) - The `tsearch' function searches in the tree pointed to by `*ROOTP' - for an element matching KEY. The function pointed to by COMPAR is - used to determine whether two elements match. *Note Comparison - Functions::, for a specification of the functions which can be - used for the COMPAR parameter. - - If the tree does not contain a matching entry the KEY value will - be added to the tree. `tsearch' does not make a copy of the object - pointed to by KEY (how could it since the size is unknown). - Instead it adds a reference to this object which means the object - must be available as long as the tree data structure is used. - - The tree is represented by a pointer to a pointer since it is - sometimes necessary to change the root node of the tree. So it - must not be assumed that the variable pointed to by ROOTP has the - same value after the call. This also shows that it is not safe to - call the `tsearch' function more than once at the same time using - the same tree. It is no problem to run it more than once at a - time on different trees. - - The return value is a pointer to the matching element in the tree. - If a new element was created the pointer points to the new data - (which is in fact KEY). If an entry had to be created and the - program ran out of space `NULL' is returned. - - - Function: void * tfind (const void *KEY, void *const *ROOTP, - comparison_fn_t COMPAR) - The `tfind' function is similar to the `tsearch' function. It - locates an element matching the one pointed to by KEY and returns - a pointer to this element. But if no matching element is - available no new element is entered (note that the ROOTP parameter - points to a constant pointer). Instead the function returns - `NULL'. - - Another advantage of the `tsearch' function in contrast to the -`hsearch' functions is that there is an easy way to remove elements. - - - Function: void * tdelete (const void *KEY, void **ROOTP, - comparison_fn_t COMPAR) - To remove a specific element matching KEY from the tree `tdelete' - can be used. It locates the matching element using the same - method as `tfind'. The corresponding element is then removed and - a pointer to the parent of the deleted node is returned by the - function. If there is no matching entry in the tree nothing can be - deleted and the function returns `NULL'. If the root of the tree - is deleted `tdelete' returns some unspecified value not equal to - `NULL'. - - - Function: void tdestroy (void *VROOT, __free_fn_t FREEFCT) - If the complete search tree has to be removed one can use - `tdestroy'. It frees all resources allocated by the `tsearch' - function to generate the tree pointed to by VROOT. - - For the data in each tree node the function FREEFCT is called. - The pointer to the data is passed as the argument to the function. - If no such work is necessary FREEFCT must point to a function - doing nothing. It is called in any case. - - This function is a GNU extension and not covered by the System V or - X/Open specifications. - - In addition to the function to create and destroy the tree data -structure, there is another function which allows you to apply a -function to all elements of the tree. The function must have this type: - - void __action_fn_t (const void *nodep, VISIT value, int level); - - The NODEP is the data value of the current node (once given as the -KEY argument to `tsearch'). LEVEL is a numeric value which corresponds -to the depth of the current node in the tree. The root node has the -depth 0 and its children have a depth of 1 and so on. The `VISIT' type -is an enumeration type. - - - Data Type: VISIT - The `VISIT' value indicates the status of the current node in the - tree and how the function is called. The status of a node is - either `leaf' or `internal node'. For each leaf node the function - is called exactly once, for each internal node it is called three - times: before the first child is processed, after the first child - is processed and after both children are processed. This makes it - possible to handle all three methods of tree traversal (or even a - combination of them). - - `preorder' - The current node is an internal node and the function is - called before the first child was processed. - - `postorder' - The current node is an internal node and the function is - called after the first child was processed. - - `endorder' - The current node is an internal node and the function is - called after the second child was processed. - - `leaf' - The current node is a leaf. - - - Function: void twalk (const void *ROOT, __action_fn_t ACTION) - For each node in the tree with a node pointed to by ROOT, the - `twalk' function calls the function provided by the parameter - ACTION. For leaf nodes the function is called exactly once with - VALUE set to `leaf'. For internal nodes the function is called - three times, setting the VALUE parameter or ACTION to the - appropriate value. The LEVEL argument for the ACTION function is - computed while descending the tree with increasing the value by - one for the descend to a child, starting with the value 0 for the - root node. - - Since the functions used for the ACTION parameter to `twalk' must - not modify the tree data, it is safe to run `twalk' in more than - one thread at the same time, working on the same tree. It is also - safe to call `tfind' in parallel.

The symbols described here are all declared in -`fnmatch.h'. - - - Function: int fnmatch (const char *PATTERN, const char *STRING, int - FLAGS) - This function tests whether the string STRING matches the pattern - PATTERN. It returns `0' if they do match; otherwise, it returns - the nonzero value `FNM_NOMATCH'. The arguments PATTERN and STRING - are both strings. - - The argument FLAGS is a combination of flag bits that alter the - details of matching. See below for a list of the defined flags. - - In the GNU C Library, `fnmatch' cannot experience an "error"--it - always returns an answer for whether the match succeeds. However, - other implementations of `fnmatch' might sometimes report "errors". - They would do so by returning nonzero values that are not equal to - `FNM_NOMATCH'. - - These are the available flags for the FLAGS argument: - -`FNM_FILE_NAME' - Treat the `/' character specially, for matching file names. If - this flag is set, wildcard constructs in PATTERN cannot match `/' - in STRING. Thus, the only way to match `/' is with an explicit - `/' in PATTERN. - -`FNM_PATHNAME' - This is an alias for `FNM_FILE_NAME'; it comes from POSIX.2. We - don't recommend this name because we don't use the term "pathname" - for file names. - -`FNM_PERIOD' - Treat the `.' character specially if it appears at the beginning of - STRING. If this flag is set, wildcard constructs in PATTERN - cannot match `.' as the first character of STRING. - - If you set both `FNM_PERIOD' and `FNM_FILE_NAME', then the special - treatment applies to `.' following `/' as well as to `.' at the - beginning of STRING. (The shell uses the `FNM_PERIOD' and - `FNM_FILE_NAME' flags together for matching file names.) - -`FNM_NOESCAPE' - Don't treat the `\' character specially in patterns. Normally, - `\' quotes the following character, turning off its special meaning - (if any) so that it matches only itself. When quoting is enabled, - the pattern `\?' matches only the string `?', because the question - mark in the pattern acts like an ordinary character. - - If you use `FNM_NOESCAPE', then `\' is an ordinary character. - -`FNM_LEADING_DIR' - Ignore a trailing sequence of characters starting with a `/' in - STRING; that is to say, test whether STRING starts with a - directory name that PATTERN matches. - - If this flag is set, either `foo*' or `foobar' as a pattern would - match the string `foobar/frobozz'. - -`FNM_CASEFOLD' - Ignore case in comparing STRING to PATTERN. - -`FNM_EXTMATCH' - Recognize beside the normal patterns also the extended patterns - introduced in `ksh'. The patterns are written in the form - explained in the following table where PATTERN-LIST is a `|' - separated list of patterns. - - `?(PATTERN-LIST)' - The pattern matches if zero or one occurrences of any of the - patterns in the PATTERN-LIST allow matching the input string. - - `*(PATTERN-LIST)' - The pattern matches if zero or more occurrences of any of the - patterns in the PATTERN-LIST allow matching the input string. - - `+(PATTERN-LIST)' - The pattern matches if one or more occurrences of any of the - patterns in the PATTERN-LIST allow matching the input string. - - `@(PATTERN-LIST)' - The pattern matches if exactly one occurrence of any of the - patterns in the PATTERN-LIST allows matching the input string. - - `!(PATTERN-LIST)' - The pattern matches if the input string cannot be matched - with any of the patterns in the PATTERN-LIST. - - -File: libc.info, Node: Globbing, Next: Regular Expressions, Prev: Wildcard Matching, Up: Pattern Matching - -Globbing -======== - - The archetypal use of wildcards is for matching against the files in -a directory, and making a list of all the matches.

It puts the result in a newly allocated - vector, and stores the size and address of this vector into - `*VECTOR-PTR'. The argument FLAGS is a combination of bit flags; - see *Note Flags for Globbing::, for details of the flags. - - The result of globbing is a sequence of file names. The function - `glob' allocates a string for each resulting word, then allocates - a vector of type `char **' to store the addresses of these - strings. The last element of the vector is a null pointer. This - vector is called the "word vector". - - To return this vector, `glob' stores both its address and its - length (number of elements, not counting the terminating null - pointer) into `*VECTOR-PTR'. - - Normally, `glob' sorts the file names alphabetically before - returning them. You can turn this off with the flag `GLOB_NOSORT' - if you want to get the information as fast as possible. Usually - it's a good idea to let `glob' sort them--if you process the files - in alphabetical order, the users will have a feel for the rate of - progress that your application is making. - - If `glob' succeeds, it returns 0. Otherwise, it returns one of - these error codes: - - `GLOB_ABORTED' - There was an error opening a directory, and you used the flag - `GLOB_ERR' or your specified ERRFUNC returned a nonzero value. - *Note Flags for Globbing::, for an explanation of the - `GLOB_ERR' flag and ERRFUNC. - - `GLOB_NOMATCH' - The pattern didn't match any existing files. If you use the - `GLOB_NOCHECK' flag, then you never get this error code, - because that flag tells `glob' to _pretend_ that the pattern - matched at least one file. - - `GLOB_NOSPACE' - It was impossible to allocate memory to hold the result. - - In the event of an error, `glob' stores information in - `*VECTOR-PTR' about all the matches it has found so far. - - It is important to notice that the `glob' function will not fail if - it encounters directories or files which cannot be handled without - the LFS interfaces. The implementation of `glob' is supposed to - use these functions internally. This at least is the assumptions - made by the Unix standard. The GNU extension of allowing the user - to provide own directory handling and `stat' functions complicates - things a bit. If these callback functions are used and a large - file or directory is encountered `glob' _can_ fail. - - - Function: int glob64 (const char *PATTERN, int FLAGS, int (*ERRFUNC) - (const char *FILENAME, int ERROR-CODE), glob64_t *VECTOR-PTR) - The `glob64' function was added as part of the Large File Summit - extensions but is not part of the original LFS proposal. The - reason for this is simple: it is not necessary. The necessity for - a `glob64' function is added by the extensions of the GNU `glob' - implementation which allows the user to provide own directory - handling and `stat' functions. The `readdir' and `stat' functions - do depend on the choice of `_FILE_OFFSET_BITS' since the definition - of the types `struct dirent' and `struct stat' will change - depending on the choice. - - Beside this difference the `glob64' works just like `glob' in all - aspects. - - This function is a GNU extension. - - -File: libc.info, Node: Flags for Globbing, Next: More Flags for Globbing, Prev: Calling Glob, Up: Globbing - -Flags for Globbing ------------------- - - This section describes the flags that you can specify in the FLAGS -argument to `glob'. Choose the flags you want, and combine them with -the C bitwise OR operator `|'. - -`GLOB_APPEND' - Append the words from this expansion to the vector of words - produced by previous calls to `glob'. This way you can - effectively expand several words as if they were concatenated with - spaces between them. - - In order for appending to work, you must not modify the contents - of the word vector structure between calls to `glob'. And, if you - set `GLOB_DOOFFS' in the first call to `glob', you must also set - it when you append to the results. - - Note that the pointer stored in `gl_pathv' may no longer be valid - after you call `glob' the second time, because `glob' might have - relocated the vector. So always fetch `gl_pathv' from the - `glob_t' structure after each `glob' call; *never* save the - pointer across calls. - -`GLOB_DOOFFS' - Leave blank slots at the beginning of the vector of words. The - `gl_offs' field says how many slots to leave. The blank slots - contain null pointers. - -`GLOB_ERR' - Give up right away and report an error if there is any difficulty - reading the directories that must be read in order to expand - PATTERN fully. Such difficulties might include a directory in - which you don't have the requisite access. Normally, `glob' tries - its best to keep on going despite any errors, reading whatever - directories it can. - - You can exercise even more control than this by specifying an - error-handler function ERRFUNC when you call `glob'. If ERRFUNC - is not a null pointer, then `glob' doesn't give up right away when - it can't read a directory; instead, it calls ERRFUNC with two - arguments, like this: - - (*ERRFUNC) (FILENAME, ERROR-CODE) - - The argument FILENAME is the name of the directory that `glob' - couldn't open or couldn't read, and ERROR-CODE is the `errno' - value that was reported to `glob'. - - If the error handler function returns nonzero, then `glob' gives up - right away. Otherwise, it continues. - -`GLOB_MARK' - If the pattern matches the name of a directory, append `/' to the - directory's name when returning it. - -`GLOB_NOCHECK' - If the pattern doesn't match any file names, return the pattern - itself as if it were a file name that had been matched. - (Normally, when the pattern doesn't match anything, `glob' returns - that there were no matches.) - -`GLOB_NOSORT' - Don't sort the file names; return them in no particular order. - (In practice, the order will depend on the order of the entries in - the directory.) The only reason _not_ to sort is to save time. - -`GLOB_NOESCAPE' - Don't treat the `\' character specially in patterns. Normally, - `\' quotes the following character, turning off its special meaning - (if any) so that it matches only itself. When quoting is enabled, - the pattern `\?' matches only the string `?', because the question - mark in the pattern acts like an ordinary character. - - If you use `GLOB_NOESCAPE', then `\' is an ordinary character. - - `glob' does its work by calling the function `fnmatch' repeatedly. - It handles the flag `GLOB_NOESCAPE' by turning on the - `FNM_NOESCAPE' flag in calls to `fnmatch'. - - -File: libc.info, Node: More Flags for Globbing, Prev: Flags for Globbing, Up: Globbing - -More Flags for Globbing ------------------------ - - Beside the flags described in the last section, the GNU -implementation of `glob' allows a few more flags which are also defined -in the `glob.h' file. Some of the extensions implement functionality -which is available in modern shell implementations. - -`GLOB_PERIOD' - The `.' character (period) is treated special. It cannot be - matched by wildcards. *Note Wildcard Matching::, `FNM_PERIOD'. - -`GLOB_MAGCHAR' - The `GLOB_MAGCHAR' value is not to be given to `glob' in the FLAGS - parameter. Instead, `glob' sets this bit in the GL_FLAGS element - of the GLOB_T structure provided as the result if the pattern used - for matching contains any wildcard character. - -`GLOB_ALTDIRFUNC' - Instead of the using the using the normal functions for accessing - the filesystem the `glob' implementation uses the user-supplied - functions specified in the structure pointed to by PGLOB - parameter. For more information about the functions refer to the - sections about directory handling see *Note Accessing - Directories::, and *Note Reading Attributes::. - -`GLOB_BRACE' - If this flag is given the handling of braces in the pattern is - changed. It is now required that braces appear correctly grouped. - I.e., for each opening brace there must be a closing one. Braces - can be used recursively. So it is possible to define one brace - expression in another one. It is important to note that the range - of each brace expression is completely contained in the outer - brace expression (if there is one). - - The string between the matching braces is separated into single - expressions by splitting at `,' (comma) characters. The commas - themselves are discarded. Please note what we said above about - recursive brace expressions. The commas used to separate the - subexpressions must be at the same level. Commas in brace - subexpressions are not matched. They are used during expansion of - the brace expression of the deeper level. The example below shows - this - - glob ("{foo/{,bar,biz},baz}", GLOB_BRACE, NULL, &result) - - is equivalent to the sequence - - glob ("foo/", GLOB_BRACE, NULL, &result) - glob ("foo/bar", GLOB_BRACE|GLOB_APPEND, NULL, &result) - glob ("foo/biz", GLOB_BRACE|GLOB_APPEND, NULL, &result) - glob ("baz", GLOB_BRACE|GLOB_APPEND, NULL, &result) - - if we leave aside error handling. - -`GLOB_NOMAGIC' - If the pattern contains no wildcard constructs (it is a literal - file name), return it as the sole "matching" word, even if no file - exists by that name. - -`GLOB_TILDE' - If this flag is used the character `~' (tilde) is handled special - if it appears at the beginning of the pattern. Instead of being - taken verbatim it is used to represent the home directory of a - known user. - - If `~' is the only character in pattern or it is followed by a `/' - (slash), the home directory of the process owner is substituted. - Using `getlogin' and `getpwnam' the information is read from the - system databases. As an example take user `bart' with his home - directory at `/home/bart'. For him a call like - - glob ("~/bin/*", GLOB_TILDE, NULL, &result) - - would return the contents of the directory `/home/bart/bin'. - Instead of referring to the own home directory it is also possible - to name the home directory of other users. To do so one has to - append the user name after the tilde character. So the contents - of user `homer''s `bin' directory can be retrieved by - - glob ("~homer/bin/*", GLOB_TILDE, NULL, &result) - - If the user name is not valid or the home directory cannot be - determined for some reason the pattern is left untouched and - itself used as the result. I.e., if in the last example `home' is - not available the tilde expansion yields to `"~homer/bin/*"' and - `glob' is not looking for a directory named `~homer'. - - This functionality is equivalent to what is available in C-shells - if the `nonomatch' flag is set. - -`GLOB_TILDE_CHECK' - If this flag is used `glob' behaves like as if `GLOB_TILDE' is - given. The only difference is that if the user name is not - available or the home directory cannot be determined for other - reasons this leads to an error. `glob' will return `GLOB_NOMATCH' - instead of using the pattern itself as the name. - - This functionality is equivalent to what is available in C-shells - if `nonomatch' flag is not set. - -`GLOB_ONLYDIR' - If this flag is used the globbing function takes this as a *hint* - that the caller is only interested in directories matching the - pattern. If the information about the type of the file is easily - available non-directories will be rejected but no extra work will - be done to determine the information for each file. I.e., the - caller must still be able to filter directories out. - - This functionality is only available with the GNU `glob' - implementation. It is mainly used internally to increase the - performance but might be useful for a user as well and therefore is - documented here. - - Calling `glob' will in most cases allocate resources which are used -to represent the result of the function call. If the same object of -type `glob_t' is used in multiple call to `glob' the resources are -freed or reused so that no leaks appear. But this does not include the -time when all `glob' calls are done. - - - Function: void globfree (glob_t *PGLOB) - The `globfree' function frees all resources allocated by previous - calls to `glob' associated with the object pointed to by PGLOB. - This function should be called whenever the currently used - `glob_t' typed object isn't used anymore. - - - Function: void globfree64 (glob64_t *PGLOB) - This function is equivalent to `globfree' but it frees records of - type `glob64_t' which were allocated by `glob64'. - - -File: libc.info, Node: Regular Expressions, Next: Word Expansion, Prev: Globbing, Up: Pattern Matching - -Regular Expression Matching -=========================== - - The GNU C library supports two interfaces for matching regular -expressions. One is the standard POSIX.2 interface, and the other is -what the GNU system has had for many years. - - Both interfaces are declared in the header file `regex.h'.

This is not true compilation--it produces a special data -structure, not machine instructions. But it is like ordinary -compilation in that its purpose is to enable you to "execute" the -pattern fast. (*Note Matching POSIX Regexps::, for how to use the -compiled regular expression for matching.) - - There is a special data type for compiled regular expressions: - - - Data Type: regex_t - This type of object holds a compiled regular expression. It is - actually a structure. It has just one field that your programs - should look at: - - `re_nsub' - This field holds the number of parenthetical subexpressions - in the regular expression that was compiled. - - There are several other fields, but we don't describe them here, - because only the functions in the library should use them. - - After you create a `regex_t' object, you can compile a regular -expression into it by calling `regcomp'. - - - Function: int regcomp (regex_t *COMPILED, const char *PATTERN, int - CFLAGS) - The function `regcomp' "compiles" a regular expression into a data - structure that you can use with `regexec' to match against a - string. The compiled regular expression format is designed for - efficient matching. `regcomp' stores it into `*COMPILED'. - - It's up to you to allocate an object of type `regex_t' and pass its - address to `regcomp'. - - The argument CFLAGS lets you specify various options that control - the syntax and semantics of regular expressions. *Note Flags for - POSIX Regexps::. - - If you use the flag `REG_NOSUB', then `regcomp' omits from the - compiled regular expression the information necessary to record - how subexpressions actually match. In this case, you might as well - pass `0' for the MATCHPTR and NMATCH arguments when you call - `regexec'. - - If you don't use `REG_NOSUB', then the compiled regular expression - does have the capacity to record how subexpressions match. Also, - `regcomp' tells you how many subexpressions PATTERN has, by - storing the number in `COMPILED->re_nsub'. You can use that value - to decide how long an array to allocate to hold information about - subexpression matches. - - `regcomp' returns `0' if it succeeds in compiling the regular - expression; otherwise, it returns a nonzero error code (see the - table below). You can use `regerror' to produce an error message - string describing the reason for a nonzero value; see *Note Regexp - Cleanup::. - - - Here are the possible nonzero values that `regcomp' can return: - -`REG_BADBR' - There was an invalid `\{...\}' construct in the regular - expression. A valid `\{...\}' construct must contain either a - single number, or two numbers in increasing order separated by a - comma. - -`REG_BADPAT' - There was a syntax error in the regular expression. - -`REG_BADRPT' - A repetition operator such as `?' or `*' appeared in a bad - position (with no preceding subexpression to act on). - -`REG_ECOLLATE' - The regular expression referred to an invalid collating element - (one not defined in the current locale for string collation). - *Note Locale Categories::. - -`REG_ECTYPE' - The regular expression referred to an invalid character class name. - -`REG_EESCAPE' - The regular expression ended with `\'. - -`REG_ESUBREG' - There was an invalid number in the `\DIGIT' construct. - -`REG_EBRACK' - There were unbalanced square brackets in the regular expression. - -`REG_EPAREN' - An extended regular expression had unbalanced parentheses, or a - basic regular expression had unbalanced `\(' and `\)'. - -`REG_EBRACE' - The regular expression had unbalanced `\{' and `\}'. - -`REG_ERANGE' - One of the endpoints in a range expression was invalid. - -`REG_ESPACE' - `regcomp' ran out of memory. - - -File: libc.info, Node: Flags for POSIX Regexps, Next: Matching POSIX Regexps, Prev: POSIX Regexp Compilation, Up: Regular Expressions - -Flags for POSIX Regular Expressions ------------------------------------ - - These are the bit flags that you can use in the CFLAGS operand when -compiling a regular expression with `regcomp'. - -`REG_EXTENDED' - Treat the pattern as an extended regular expression, rather than - as a basic regular expression. - -`REG_ICASE' - Ignore case when matching letters. - -`REG_NOSUB' - Don't bother storing the contents of the MATCHES-PTR array. - -`REG_NEWLINE' - Treat a newline in STRING as dividing STRING into multiple lines, - so that `$' can match before the newline and `^' can match after. - Also, don't permit `.' to match a newline, and don't permit - `[^...]' to match a newline. - - Otherwise, newline acts like any other ordinary character. - - -File: libc.info, Node: Matching POSIX Regexps, Next: Regexp Subexpressions, Prev: Flags for POSIX Regexps, Up: Regular Expressions - -Matching a Compiled POSIX Regular Expression --------------------------------------------- - - Once you have compiled a regular expression, as described in *Note -POSIX Regexp Compilation::, you can match it against strings using -`regexec'.

It returns that information -by storing the offsets into an array whose elements are structures of -type `regmatch_t'. The first element of the array (index `0') records -the part of the string that matched the entire regular expression. -Each other element of the array records the beginning and end of the -part that matched a single parenthetical subexpression. - - - Data Type: regmatch_t - This is the data type of the MATCHARRAY array that you pass to - `regexec'. It contains two structure fields, as follows: - - `rm_so' - The offset in STRING of the beginning of a substring. Add - this value to STRING to get the address of that part. - - `rm_eo' - The offset in STRING of the end of the substring. - - - Data Type: regoff_t - `regoff_t' is an alias for another signed integer type. The - fields of `regmatch_t' have type `regoff_t'. - - The `regmatch_t' elements correspond to subexpressions positionally; -the first element (index `1') records where the first subexpression -matched, the second element records the second subexpression, and so -on. The order of the subexpressions is the order in which they begin. - - When you call `regexec', you specify how long the MATCHPTR array is, -with the NMATCH argument. This tells `regexec' how many elements to -store. If the actual regular expression has more than NMATCH -subexpressions, then you won't get offset information about the rest of -them. But this doesn't alter whether the pattern matches a particular -string or not. - - If you don't want `regexec' to return any information about where -the subexpressions matched, you can either supply `0' for NMATCH, or -use the flag `REG_NOSUB' when you compile the pattern with `regcomp'. - - -File: libc.info, Node: Subexpression Complications, Next: Regexp Cleanup, Prev: Regexp Subexpressions, Up: Regular Expressions - -Complications in Subexpression Matching ---------------------------------------- - - Sometimes a subexpression matches a substring of no characters. This -happens when `f\(o*\)' matches the string `fum'. (It really matches -just the `f'.) In this case, both of the offsets identify the point in -the string where the null substring was found. In this example, the -offsets are both `1'. - - Sometimes the entire regular expression can match without using some -of its subexpressions at all--for example, when `ba\(na\)*' matches the -string `ba', the parenthetical subexpression is not used. When this -happens, `regexec' stores `-1' in both fields of the element for that -subexpression. - - Sometimes matching the entire regular expression can match a -particular subexpression more than once--for example, when `ba\(na\)*' -matches the string `bananana', the parenthetical subexpression matches -three times. When this happens, `regexec' usually stores the offsets -of the last part of the string that matched the subexpression. In the -case of `bananana', these offsets are `6' and `8'. - - But the last match is not always the one that is chosen. It's more -accurate to say that the last _opportunity_ to match is the one that -takes precedence. What this means is that when one subexpression -appears within another, then the results reported for the inner -subexpression reflect whatever happened on the last match of the outer -subexpression. For an example, consider `\(ba\(na\)*s \)*' matching -the string `bananas bas '. The last time the inner expression actually -matches is near the end of the first word. But it is _considered_ -again in the second word, and fails to match there. `regexec' reports -nonuse of the "na" subexpression. - - Another place where this rule applies is when the regular expression - \(ba\(na\)*s \|nefer\(ti\)* \)* - -matches `bananas nefertiti'. The "na" subexpression does match in the -first word, but it doesn't match in the second word because the other -alternative is used there. Once again, the second repetition of the -outer subexpression overrides the first, and within that second -repetition, the "na" subexpression is not used. So `regexec' reports -nonuse of the "na" subexpression. - - -File: libc.info, Node: Regexp Cleanup, Prev: Subexpression Complications, Up: Regular Expressions - -POSIX Regexp Matching Cleanup ------------------------------ - - When you are finished using a compiled regular expression, you can -free the storage it uses by calling `regfree'. - - - Function: void regfree (regex_t *COMPILED) - Calling `regfree' frees all the storage that `*COMPILED' points - to. This includes various internal fields of the `regex_t' - structure that aren't documented in this manual. - - `regfree' does not free the object `*COMPILED' itself. - - You should always free the space in a `regex_t' structure with -`regfree' before using the structure to compile another regular -expression. - - When `regcomp' or `regexec' reports an error, you can use the -function `regerror' to turn it into an error message string. - - - Function: size_t regerror (int ERRCODE, regex_t *COMPILED, char - *BUFFER, size_t LENGTH) - This function produces an error message string for the error code - ERRCODE, and stores the string in LENGTH bytes of memory starting - at BUFFER. For the COMPILED argument, supply the same compiled - regular expression structure that `regcomp' or `regexec' was - working with when it got the error. Alternatively, you can supply - `NULL' for COMPILED; you will still get a meaningful error - message, but it might not be as detailed. - - If the error message can't fit in LENGTH bytes (including a - terminating null character), then `regerror' truncates it.

Next, three different transformations are applied in the same step, - from left to right: - - * "Variable substitution": Environment variables are - substituted for references such as `$foo'. - - * "Command substitution": Constructs such as ``cat foo`' and - the equivalent `$(cat foo)' are replaced with the output from - the inner command. - - * "Arithmetic expansion": Constructs such as `$(($x-1))' are - replaced with the result of the arithmetic computation. - - 3. "Field splitting": subdivision of the text into "words". - - 4. "Wildcard expansion": The replacement of a construct such as `*.c' - with a list of `.c' file names. Wildcard expansion applies to an - entire word at a time, and replaces that word with 0 or more file - names that are themselves words. - - 5.

To return this -vector, `wordexp' uses a special data type, `wordexp_t', which is a -structure. You pass `wordexp' the address of the structure, and it -fills in the structure's fields to tell you about the results. - - - Data Type: wordexp_t - This data type holds a pointer to a word vector. More precisely, - it records both the address of the word vector and its size. - - `we_wordc' - The number of elements in the vector. - - `we_wordv' - The address of the vector. This field has type `char **'. - - `we_offs' - The offset of the first real element of the vector, from its - nominal address in the `we_wordv' field. Unlike the other - fields, this is always an input to `wordexp', rather than an - output from it. - - If you use a nonzero offset, then that many elements at the - beginning of the vector are left empty. (The `wordexp' - function fills them with null pointers.) - - The `we_offs' field is meaningful only if you use the - `WRDE_DOOFFS' flag. Otherwise, the offset is always zero - regardless of what is in this field, and the first real - element comes at the beginning of the vector. - - - Function: int wordexp (const char *WORDS, wordexp_t - *WORD-VECTOR-PTR, int FLAGS) - Perform word expansion on the string WORDS, putting the result in - a newly allocated vector, and store the size and address of this - vector into `*WORD-VECTOR-PTR'. The argument FLAGS is a - combination of bit flags; see *Note Flags for Wordexp::, for - details of the flags. - - You shouldn't use any of the characters `|&;<>' in the string - WORDS unless they are quoted; likewise for newline. If you use - these characters unquoted, you will get the `WRDE_BADCHAR' error - code. Don't use parentheses or braces unless they are quoted or - part of a word expansion construct. If you use quotation - characters `'"`', they should come in pairs that balance. - - The results of word expansion are a sequence of words. The - function `wordexp' allocates a string for each resulting word, then - allocates a vector of type `char **' to store the addresses of - these strings. The last element of the vector is a null pointer. - This vector is called the "word vector". - - To return this vector, `wordexp' stores both its address and its - length (number of elements, not counting the terminating null - pointer) into `*WORD-VECTOR-PTR'. - - If `wordexp' succeeds, it returns 0. Otherwise, it returns one of - these error codes: - - `WRDE_BADCHAR' - The input string WORDS contains an unquoted invalid character - such as `|'. - - `WRDE_BADVAL' - The input string refers to an undefined shell variable, and - you used the flag `WRDE_UNDEF' to forbid such references. - - `WRDE_CMDSUB' - The input string uses command substitution, and you used the - flag `WRDE_NOCMD' to forbid command substitution. - - `WRDE_NOSPACE' - It was impossible to allocate memory to hold the result. In - this case, `wordexp' can store part of the results--as much - as it could allocate room for. - - `WRDE_SYNTAX' - There was a syntax error in the input string. For example, - an unmatched quoting character is a syntax error. - - - Function: void wordfree (wordexp_t *WORD-VECTOR-PTR) - Free the storage used for the word-strings and vector that - `*WORD-VECTOR-PTR' points to. This does not free the structure - `*WORD-VECTOR-PTR' itself--only the other data it points to. - - -File: libc.info, Node: Flags for Wordexp, Next: Wordexp Example, Prev: Calling Wordexp, Up: Word Expansion - -Flags for Word Expansion ------------------------- - - This section describes the flags that you can specify in the FLAGS -argument to `wordexp'. Choose the flags you want, and combine them -with the C operator `|'. - -`WRDE_APPEND' - Append the words from this expansion to the vector of words - produced by previous calls to `wordexp'. This way you can - effectively expand several words as if they were concatenated with - spaces between them. - - In order for appending to work, you must not modify the contents - of the word vector structure between calls to `wordexp'. And, if - you set `WRDE_DOOFFS' in the first call to `wordexp', you must also - set it when you append to the results. - -`WRDE_DOOFFS' - Leave blank slots at the beginning of the vector of words. The - `we_offs' field says how many slots to leave. The blank slots - contain null pointers. - -`WRDE_NOCMD' - Don't do command substitution; if the input requests command - substitution, report an error. - -`WRDE_REUSE' - Reuse a word vector made by a previous call to `wordexp'. Instead - of allocating a new vector of words, this call to `wordexp' will - use the vector that already exists (making it larger if necessary). - - Note that the vector may move, so it is not safe to save an old - pointer and use it again after calling `wordexp'. You must fetch - `we_pathv' anew after each call. - -`WRDE_SHOWERR' - Do show any error messages printed by commands run by command - substitution. More precisely, allow these commands to inherit the - standard error output stream of the current process. By default, - `wordexp' gives these commands a standard error stream that - discards all output. - -`WRDE_UNDEF' - If the input refers to a shell variable that is not defined, - report an error. - - -File: libc.info, Node: Wordexp Example, Next: Tilde Expansion, Prev: Flags for Wordexp, Up: Word Expansion - -`wordexp' Example ------------------ - - Here is an example of using `wordexp' to expand several strings and -use the results to run a shell command. It also shows the use of -`WRDE_APPEND' to concatenate the expansions and of `wordfree' to free -the space allocated by `wordexp'. - - int - expand_and_execute (const char *program, const char **options) - { - wordexp_t result; - pid_t pid - int status, i; - - /* Expand the string for the program to run. */ - switch (wordexp (program, &result, 0)) - { - case 0: /* Successful. */ - break; - case WRDE_NOSPACE: - /* If the error was `WRDE_NOSPACE', - then perhaps part of the result was allocated. */ - wordfree (&result); - default: /* Some other error. */ - return -1; - } - - /* Expand the strings specified for the arguments. */ - for (i = 0; options[i] != NULL; i++) - { - if (wordexp (options[i], &result, WRDE_APPEND)) - { - wordfree (&result); - return -1; - } - } - - pid = fork (); - if (pid == 0) - { - /* This is the child process. Execute the command. */ - execv (result.we_wordv[0], result.we_wordv); - exit (EXIT_FAILURE); - } - else if (pid < 0) - /* The fork failed. Report failure. */ - status = -1; - else - /* This is the parent process. Wait for the child to complete. */ - if (waitpid (pid, &status, 0) != pid) - status = -1; - - wordfree (&result); - return status; - } - - -File: libc.info, Node: Tilde Expansion, Next: Variable Substitution, Prev: Wordexp Example, Up: Word Expansion - -Details of Tilde Expansion --------------------------- - - It's a standard part of shell syntax that you can use `~' at the -beginning of a file name to stand for your own home directory. You can -use `~USER' to stand for USER's home directory. - - "Tilde expansion" is the process of converting these abbreviations -to the directory names that they stand for. - - Tilde expansion applies to the `~' plus all following characters up -to whitespace or a slash. It takes place only at the beginning of a -word, and only if none of the characters to be transformed is quoted in -any way. - - Plain `~' uses the value of the environment variable `HOME' as the -proper home directory name. `~' followed by a user name uses -`getpwname' to look up that user in the user database, and uses -whatever directory is recorded there. Thus, `~' followed by your own -name can give different results from plain `~', if the value of `HOME' -is not really your home directory. - - -File: libc.info, Node: Variable Substitution, Prev: Tilde Expansion, Up: Word Expansion - -Details of Variable Substitution --------------------------------- - - Part of ordinary shell syntax is the use of `$VARIABLE' to -substitute the value of a shell variable into a command. This is called -"variable substitution", and it is one part of doing word expansion. - - There are two basic ways you can write a variable reference for -substitution: - -`${VARIABLE}' - If you write braces around the variable name, then it is completely - unambiguous where the variable name ends. You can concatenate - additional letters onto the end of the variable value by writing - them immediately after the close brace. For example, `${foo}s' - expands into `tractors'. - -`$VARIABLE' - If you do not put braces around the variable name, then the - variable name consists of all the alphanumeric characters and - underscores that follow the `$'. The next punctuation character - ends the variable name. Thus, `$foo-bar' refers to the variable - `foo' and expands into `tractor-bar'. - - When you use braces, you can also use various constructs to modify -the value that is substituted, or test it in various ways. - -`${VARIABLE:-DEFAULT}' - Substitute the value of VARIABLE, but if that is empty or - undefined, use DEFAULT instead. - -`${VARIABLE:=DEFAULT}' - Substitute the value of VARIABLE, but if that is empty or - undefined, use DEFAULT instead and set the variable to DEFAULT. - -`${VARIABLE:?MESSAGE}' - If VARIABLE is defined and not empty, substitute its value. - - Otherwise, print MESSAGE as an error message on the standard error - stream, and consider word expansion a failure. - -`${VARIABLE:+REPLACEMENT}' - Substitute REPLACEMENT, but only if VARIABLE is defined and - nonempty. Otherwise, substitute nothing for this construct. - -`${#VARIABLE}' - Substitute a numeral which expresses in base ten the number of - characters in the value of VARIABLE. `${#foo}' stands for `7', - because `tractor' is seven characters. - - These variants of variable substitution let you remove part of the -variable's value before substituting it. The PREFIX and SUFFIX are not -mere strings; they are wildcard patterns, just like the patterns that -you use to match multiple file names. But in this context, they match -against parts of the variable value rather than against file names. - -`${VARIABLE%%SUFFIX}' - Substitute the value of VARIABLE, but first discard from that - variable any portion at the end that matches the pattern SUFFIX. - - If there is more than one alternative for how to match against - SUFFIX, this construct uses the longest possible match. - - Thus, `${foo%%r*}' substitutes `t', because the largest match for - `r*' at the end of `tractor' is `ractor'. - -`${VARIABLE%SUFFIX}' - Substitute the value of VARIABLE, but first discard from that - variable any portion at the end that matches the pattern SUFFIX. - - If there is more than one alternative for how to match against - SUFFIX, this construct uses the shortest possible alternative. - - Thus, `${foo%r*}' substitutes `tracto', because the shortest match - for `r*' at the end of `tractor' is just `r'. - -`${VARIABLE##PREFIX}' - Substitute the value of VARIABLE, but first discard from that - variable any portion at the beginning that matches the pattern - PREFIX. - - If there is more than one alternative for how to match against - PREFIX, this construct uses the longest possible match. - - Thus, `${foo##*t}' substitutes `or', because the largest match for - `*t' at the beginning of `tractor' is `tract'. - -`${VARIABLE#PREFIX}' - Substitute the value of VARIABLE, but first discard from that - variable any portion at the beginning that matches the pattern - PREFIX. - - If there is more than one alternative for how to match against - PREFIX, this construct uses the shortest possible alternative. - - Thus, `${foo#*t}' substitutes `ractor', because the shortest match - for `*t' at the beginning of `tractor' is just `t'. - - -File: libc.info, Node: I/O Overview, Next: I/O on Streams, Prev: Pattern Matching, Up: Top - -Input/Output Overview -********************* - - Most programs need to do either input (reading data) or output -(writing data), or most frequently both, in order to do anything -useful. The GNU C library provides such a large selection of input and -output functions that the hardest part is often deciding which function -is most appropriate! - - This chapter introduces concepts and terminology relating to input -and output. Other chapters relating to the GNU I/O facilities are: - - * *Note I/O on Streams::, which covers the high-level functions that - operate on streams, including formatted input and output. - - * *Note Low-Level I/O::, which covers the basic I/O and control - functions on file descriptors. - - * *Note File System Interface::, which covers functions for - operating on directories and for manipulating file attributes such - as access modes and ownership. - - * *Note Pipes and FIFOs::, which includes information on the basic - interprocess communication facilities. - - * *Note Sockets::, which covers a more complicated interprocess - communication facility with support for networking. - - * *Note Low-Level Terminal Interface::, which covers functions for - changing how input and output to terminals or other serial devices - are processed. - -* Menu: - -* I/O Concepts:: Some basic information and terminology. -* File Names:: How to refer to a file. - - -File: libc.info, Node: I/O Concepts, Next: File Names, Up: I/O Overview - -Input/Output Concepts -===================== - - Before you can read or write the contents of a file, you must -establish a connection or communications channel to the file. This -process is called "opening" the file. You can open a file for reading, -writing, or both. - - The connection to an open file is represented either as a stream or -as a file descriptor. You pass this as an argument to the functions -that do the actual read or write operations, to tell them which file to -operate on. Certain functions expect streams, and others are designed -to operate on file descriptors. - - When you have finished reading to or writing from the file, you can -terminate the connection by "closing" the file. Once you have closed a -stream or file descriptor, you cannot do any more input or output -operations on it. - -* Menu: - -* Streams and File Descriptors:: The GNU Library provides two ways - to access the contents of files. -* File Position:: The number of bytes from the - beginning of the file. - - -File: libc.info, Node: Streams and File Descriptors, Next: File Position, Up: I/O Concepts - -Streams and File Descriptors ----------------------------- - - When you want to do input or output to a file, you have a choice of -two basic mechanisms for representing the connection between your -program and the file: file descriptors and streams. File descriptors -are represented as objects of type `int', while streams are represented -as `FILE *' objects. - - File descriptors provide a primitive, low-level interface to input -and output operations. Both file descriptors and streams can represent -a connection to a device (such as a terminal), or a pipe or socket for -communicating with another process, as well as a normal file. But, if -you want to do control operations that are specific to a particular kind -of device, you must use a file descriptor; there are no facilities to -use streams in this way. You must also use file descriptors if your -program needs to do input or output in special modes, such as -nonblocking (or polled) input (*note File Status Flags::). - - Streams provide a higher-level interface, layered on top of the -primitive file descriptor facilities. The stream interface treats all -kinds of files pretty much alike--the sole exception being the three -styles of buffering that you can choose (*note Stream Buffering::). - - The main advantage of using the stream interface is that the set of -functions for performing actual input and output operations (as opposed -to control operations) on streams is much richer and more powerful than -the corresponding facilities for file descriptors. The file descriptor -interface provides only simple functions for transferring blocks of -characters, but the stream interface also provides powerful formatted -input and output functions (`printf' and `scanf') as well as functions -for character- and line-oriented input and output. - - Since streams are implemented in terms of file descriptors, you can -extract the file descriptor from a stream and perform low-level -operations directly on the file descriptor. You can also initially open -a connection as a file descriptor and then make a stream associated with -that file descriptor. - - In general, you should stick with using streams rather than file -descriptors, unless there is some specific operation you want to do that -can only be done on a file descriptor. If you are a beginning -programmer and aren't sure what functions to use, we suggest that you -concentrate on the formatted input functions (*note Formatted Input::) -and formatted output functions (*note Formatted Output::). - - If you are concerned about portability of your programs to systems -other than GNU, you should also be aware that file descriptors are not -as portable as streams. You can expect any system running ISO C to -support streams, but non-GNU systems may not support file descriptors at -all, or may only implement a subset of the GNU functions that operate on -file descriptors. Most of the file descriptor functions in the GNU -library are included in the POSIX.1 standard, however. - - -File: libc.info, Node: File Position, Prev: Streams and File Descriptors, Up: I/O Concepts - -File Position -------------- - - One of the attributes of an open file is its "file position" that -keeps track of where in the file the next character is to be read or -written. In the GNU system, and all POSIX.1 systems, the file position -is simply an integer representing the number of bytes from the beginning -of the file. - - The file position is normally set to the beginning of the file when -it is opened, and each time a character is read or written, the file -position is incremented. In other words, access to the file is normally -"sequential". - - Ordinary files permit read or write operations at any position within -the file. Some other kinds of files may also permit this. Files which -do permit this are sometimes referred to as "random-access" files. You -can change the file position using the `fseek' function on a stream -(*note File Positioning::) or the `lseek' function on a file descriptor -(*note I/O Primitives::). If you try to change the file position on a -file that doesn't support random access, you get the `ESPIPE' error. - - Streams and descriptors that are opened for "append access" are -treated specially for output: output to such files is _always_ appended -sequentially to the _end_ of the file, regardless of the file position. -However, the file position is still used to control where in the file -reading is done. - - If you think about it, you'll realize that several programs can read -a given file at the same time. In order for each program to be able to -read the file at its own pace, each program must have its own file -pointer, which is not affected by anything the other programs do. - - In fact, each opening of a file creates a separate file position. -Thus, if you open a file twice even in the same program, you get two -streams or descriptors with independent file positions. - - By contrast, if you open a descriptor and then duplicate it to get -another descriptor, these two descriptors share the same file position: -changing the file position of one descriptor will affect the other. - - -File: libc.info, Node: File Names, Prev: I/O Concepts, Up: I/O Overview - -File Names -========== - - In order to open a connection to a file, or to perform other -operations such as deleting a file, you need some way to refer to the -file. Nearly all files have names that are strings--even files which -are actually devices such as tape drives or terminals. These strings -are called "file names". You specify the file name to say which file -you want to open or operate on. - - This section describes the conventions for file names and how the -operating system works with them. - -* Menu: - -* Directories:: Directories contain entries for files. -* File Name Resolution:: A file name specifies how to look up a file. -* File Name Errors:: Error conditions relating to file names. -* File Name Portability:: File name portability and syntax issues. - - -File: libc.info, Node: Directories, Next: File Name Resolution, Up: File Names - -Directories ------------ - - In order to understand the syntax of file names, you need to -understand how the file system is organized into a hierarchy of -directories. - - A "directory" is a file that contains information to associate other -files with names; these associations are called "links" or "directory -entries". Sometimes, people speak of "files in a directory", but in -reality, a directory only contains pointers to files, not the files -themselves. - - The name of a file contained in a directory entry is called a "file -name component". In general, a file name consists of a sequence of one -or more such components, separated by the slash character (`/'). A -file name which is just one component names a file with respect to its -directory. A file name with multiple components names a directory, and -then a file in that directory, and so on. - - Some other documents, such as the POSIX standard, use the term -"pathname" for what we call a file name, and either "filename" or -"pathname component" for what this manual calls a file name component. -We don't use this terminology because a "path" is something completely -different (a list of directories to search), and we think that -"pathname" used for something else will confuse users. We always use -"file name" and "file name component" (or sometimes just "component", -where the context is obvious) in GNU documentation. Some macros use -the POSIX terminology in their names, such as `PATH_MAX'. These macros -are defined by the POSIX standard, so we cannot change their names. - - You can find more detailed information about operations on -directories in *Note File System Interface::. - - -File: libc.info, Node: File Name Resolution, Next: File Name Errors, Prev: Directories, Up: File Names - -File Name Resolution --------------------- - - A file name consists of file name components separated by slash -(`/') characters. On the systems that the GNU C library supports, -multiple successive `/' characters are equivalent to a single `/' -character. - - The process of determining what file a file name refers to is called -"file name resolution". This is performed by examining the components -that make up a file name in left-to-right order, and locating each -successive component in the directory named by the previous component. -Of course, each of the files that are referenced as directories must -actually exist, be directories instead of regular files, and have the -appropriate permissions to be accessible by the process; otherwise the -file name resolution fails. - - If a file name begins with a `/', the first component in the file -name is located in the "root directory" of the process (usually all -processes on the system have the same root directory). Such a file name -is called an "absolute file name". - - Otherwise, the first component in the file name is located in the -current working directory (*note Working Directory::). This kind of -file name is called a "relative file name". - - The file name components `.' ("dot") and `..' ("dot-dot") have -special meanings. Every directory has entries for these file name -components. The file name component `.' refers to the directory -itself, while the file name component `..' refers to its "parent -directory" (the directory that contains the link for the directory in -question). As a special case, `..' in the root directory refers to the -root directory itself, since it has no parent; thus `/..' is the same -as `/'. - - Here are some examples of file names: - -`/a' - The file named `a', in the root directory. - -`/a/b' - The file named `b', in the directory named `a' in the root - directory. - -`a' - The file named `a', in the current working directory. - -`/a/./b' - This is the same as `/a/b'. - -`./a' - The file named `a', in the current working directory. - -`../a' - The file named `a', in the parent directory of the current working - directory. - - A file name that names a directory may optionally end in a `/'. You -can specify a file name of `/' to refer to the root directory, but the -empty string is not a meaningful file name. If you want to refer to -the current working directory, use a file name of `.' or `./'. - - Unlike some other operating systems, the GNU system doesn't have any -built-in support for file types (or extensions) or file versions as part -of its file name syntax. Many programs and utilities use conventions -for file names--for example, files containing C source code usually -have names suffixed with `.c'--but there is nothing in the file system -itself that enforces this kind of convention. - - -File: libc.info, Node: File Name Errors, Next: File Name Portability, Prev: File Name Resolution, Up: File Names - -File Name Errors ----------------- - - Functions that accept file name arguments usually detect these -`errno' error conditions relating to the file name syntax or trouble -finding the named file. These errors are referred to throughout this -manual as the "usual file name errors". - -`EACCES' - The process does not have search permission for a directory - component of the file name. - -`ENAMETOOLONG' - This error is used when either the total length of a file name is - greater than `PATH_MAX', or when an individual file name component - has a length greater than `NAME_MAX'. *Note Limits for Files::. - - In the GNU system, there is no imposed limit on overall file name - length, but some file systems may place limits on the length of a - component. - -`ENOENT' - This error is reported when a file referenced as a directory - component in the file name doesn't exist, or when a component is a - symbolic link whose target file does not exist. *Note Symbolic - Links::. - -`ENOTDIR' - A file that is referenced as a directory component in the file name - exists, but it isn't a directory. - -`ELOOP' - Too many symbolic links were resolved while trying to look up the - file name. The system has an arbitrary limit on the number of - symbolic links that may be resolved in looking up a single file - name, as a primitive way to detect loops. *Note Symbolic Links::. - - -File: libc.info, Node: File Name Portability, Prev: File Name Errors, Up: File Names - -Portability of File Names -------------------------- - - The rules for the syntax of file names discussed in *Note File -Names::, are the rules normally used by the GNU system and by other -POSIX systems. However, other operating systems may use other -conventions. - - There are two reasons why it can be important for you to be aware of -file name portability issues: - - * If your program makes assumptions about file name syntax, or - contains embedded literal file name strings, it is more difficult - to get it to run under other operating systems that use different - syntax conventions. - - * Even if you are not concerned about running your program on - machines that run other operating systems, it may still be - possible to access files that use different naming conventions. - For example, you may be able to access file systems on another - computer running a different operating system over a network, or - read and write disks in formats used by other operating systems. - - The ISO C standard says very little about file name syntax, only that -file names are strings. In addition to varying restrictions on the -length of file names and what characters can validly appear in a file -name, different operating systems use different conventions and syntax -for concepts such as structured directories and file types or -extensions. Some concepts such as file versions might be supported in -some operating systems and not by others. - - The POSIX.1 standard allows implementations to put additional -restrictions on file name syntax, concerning what characters are -permitted in file names and on the length of file name and file name -component strings. However, in the GNU system, you do not need to worry -about these restrictions; any character except the null character is -permitted in a file name string, and there are no limits on the length -of file name strings. - - -File: libc.info, Node: I/O on Streams, Next: Low-Level I/O, Prev: I/O Overview, Up: Top - -Input/Output on Streams -*********************** - - This chapter describes the functions for creating streams and -performing input and output operations on them.

Since most -of the library functions deal with objects of type `FILE *', sometimes -the term "file pointer" is also used to mean "stream". This leads to -unfortunate confusion over terminology in many books on C. This -manual, however, is careful to use the terms "file" and "stream" only -in the technical sense. - - The `FILE' type is declared in the header file `stdio.h'. - - - Data Type: FILE - This is the data type used to represent stream objects. A `FILE' - object holds all of the internal state information about the - connection to the associated file, including such things as the - file position indicator and buffering information. Each stream - also has error and end-of-file status indicators that can be - tested with the `ferror' and `feof' functions; see *Note EOF and - Errors::. - - `FILE' objects are allocated and managed internally by the -input/output library functions. Don't try to create your own objects of -type `FILE'; let the library do it. Your programs should deal only -with pointers to these objects (that is, `FILE *' values) rather than -the objects themselves. - - -File: libc.info, Node: Standard Streams, Next: Opening Streams, Prev: Streams, Up: I/O on Streams - -Standard Streams -================ - - When the `main' function of your program is invoked, it already has -three predefined streams open and available for use. These represent -the "standard" input and output channels that have been established for -the process. - - These streams are declared in the header file `stdio.h'. - - - Variable: FILE * stdin - The "standard input" stream, which is the normal source of input - for the program. - - - Variable: FILE * stdout - The "standard output" stream, which is used for normal output from - the program. - - - Variable: FILE * stderr - The "standard error" stream, which is used for error messages and - diagnostics issued by the program. - - In the GNU system, you can specify what files or processes -correspond to these streams using the pipe and redirection facilities -provided by the shell. (The primitives shells use to implement these -facilities are described in *Note File System Interface::.) Most other -operating systems provide similar mechanisms, but the details of how to -use them can vary. - - In the GNU C library, `stdin', `stdout', and `stderr' are normal -variables which you can set just like any others. For example, to -redirect the standard output to a file, you could do: - - fclose (stdout); - stdout = fopen ("standard-output-file", "w"); - - Note however, that in other systems `stdin', `stdout', and `stderr' -are macros that you cannot assign to in the normal way. But you can -use `freopen' to get the effect of closing one and reopening it. *Note -Opening Streams::. - - The three streams `stdin', `stdout', and `stderr' are not unoriented -at program start (*note Streams and I18N::). - - -File: libc.info, Node: Opening Streams, Next: Closing Streams, Prev: Standard Streams, Up: I/O on Streams - -Opening Streams -=============== - - Opening a file with the `fopen' function creates a new stream and -establishes a connection between the stream and a file. This may -involve creating a new file. - - Everything described in this section is declared in the header file -`stdio.h'. - - - Function: FILE * fopen (const char *FILENAME, const char *OPENTYPE) - The `fopen' function opens a stream for I/O to the file FILENAME, - and returns a pointer to the stream. - - The OPENTYPE argument is a string that controls how the file is - opened and specifies attributes of the resulting stream. It must - begin with one of the following sequences of characters: - - `r' - Open an existing file for reading only. - - `w' - Open the file for writing only. If the file already exists, - it is truncated to zero length. Otherwise a new file is - created. - - `a' - Open a file for append access; that is, writing at the end of - file only. If the file already exists, its initial contents - are unchanged and output to the stream is appended to the end - of the file. Otherwise, a new, empty file is created. - - `r+' - Open an existing file for both reading and writing. The - initial contents of the file are unchanged and the initial - file position is at the beginning of the file. - - `w+' - Open a file for both reading and writing. If the file - already exists, it is truncated to zero length. Otherwise, a - new file is created. - - `a+' - Open or create file for both reading and appending. If the - file exists, its initial contents are unchanged. Otherwise, - a new file is created. The initial file position for reading - is at the beginning of the file, but output is always - appended to the end of the file. - - As you can see, `+' requests a stream that can do both input and - output. The ISO standard says that when using such a stream, you - must call `fflush' (*note Stream Buffering::) or a file positioning - function such as `fseek' (*note File Positioning::) when switching - from reading to writing or vice versa. Otherwise, internal buffers - might not be emptied properly. The GNU C library does not have - this limitation; you can do arbitrary reading and writing - operations on a stream in whatever order. - - Additional characters may appear after these to specify flags for - the call. Always put the mode (`r', `w+', etc.) first; that is - the only part you are guaranteed will be understood by all systems. - - The GNU C library defines one additional character for use in - OPENTYPE: the character `x' insists on creating a new file--if a - file FILENAME already exists, `fopen' fails rather than opening - it. If you use `x' you are guaranteed that you will not clobber - an existing file. This is equivalent to the `O_EXCL' option to - the `open' function (*note Opening and Closing Files::). - - The character `b' in OPENTYPE has a standard meaning; it requests - a binary stream rather than a text stream. But this makes no - difference in POSIX systems (including the GNU system). If both - `+' and `b' are specified, they can appear in either order. *Note - Binary Streams::. - - If the OPENTYPE string contains the sequence `,ccs=STRING' then - STRING is taken as the name of a coded character set and `fopen' - will mark the stream as wide-oriented which appropriate conversion - functions in place to convert from and to the character set STRING - is place. Any other stream is opened initially unoriented and the - orientation is decided with the first file operation. If the - first operation is a wide character operation, the stream is not - only marked as wide-oriented, also the conversion functions to - convert to the coded character set used for the current locale are - loaded. This will not change anymore from this point on even if - the locale selected for the `LC_CTYPE' category is changed. - - Any other characters in OPENTYPE are simply ignored. They may be - meaningful in other systems. - - If the open fails, `fopen' returns a null pointer. - - When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a - 32 bit machine this function is in fact `fopen64' since the LFS - interface replaces transparently the old interface. - - You can have multiple streams (or file descriptors) pointing to the -same file open at the same time. If you do only input, this works -straightforwardly, but you must be careful if any output streams are -included. *Note Stream/Descriptor Precautions::. This is equally true -whether the streams are in one program (not usual) or in several -programs (which can easily happen). It may be advantageous to use the -file locking facilities to avoid simultaneous access. *Note File -Locks::. - - - Function: FILE * fopen64 (const char *FILENAME, const char *OPENTYPE) - This function is similar to `fopen' but the stream it returns a - pointer for is opened using `open64'. Therefore this stream can be - used even on files larger then 2^31 bytes on 32 bit machines. - - Please note that the return type is still `FILE *'. There is no - special `FILE' type for the LFS interface. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `fopen' and - so transparently replaces the old interface. - - - Macro: int FOPEN_MAX - The value of this macro is an integer constant expression that - represents the minimum number of streams that the implementation - guarantees can be open simultaneously. You might be able to open - more than this many streams, but that is not guaranteed. The - value of this constant is at least eight, which includes the three - standard streams `stdin', `stdout', and `stderr'. In POSIX.1 - systems this value is determined by the `OPEN_MAX' parameter; - *note General Limits::. In BSD and GNU, it is controlled by the - `RLIMIT_NOFILE' resource limit; *note Limits on Resources::. - - - Function: FILE * freopen (const char *FILENAME, const char - *OPENTYPE, FILE *STREAM) - This function is like a combination of `fclose' and `fopen'. It - first closes the stream referred to by STREAM, ignoring any errors - that are detected in the process. (Because errors are ignored, - you should not use `freopen' on an output stream if you have - actually done any output using the stream.) Then the file named by - FILENAME is opened with mode OPENTYPE as for `fopen', and - associated with the same stream object STREAM. - - If the operation fails, a null pointer is returned; otherwise, - `freopen' returns STREAM. - - `freopen' has traditionally been used to connect a standard stream - such as `stdin' with a file of your own choice. This is useful in - programs in which use of a standard stream for certain purposes is - hard-coded. In the GNU C library, you can simply close the - standard streams and open new ones with `fopen'. But other - systems lack this ability, so using `freopen' is more portable. - - When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a - 32 bit machine this function is in fact `freopen64' since the LFS - interface replaces transparently the old interface. - - - Function: FILE * freopen64 (const char *FILENAME, const char - *OPENTYPE, FILE *STREAM) - This function is similar to `freopen'. The only difference is that - on 32 bit machine the stream returned is able to read beyond the - 2^31 bytes limits imposed by the normal interface. It should be - noted that the stream pointed to by STREAM need not be opened - using `fopen64' or `freopen64' since its mode is not important for - this function. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `freopen' - and so transparently replaces the old interface. - - In some situations it is useful to know whether a given stream is -available for reading or writing. This information is normally not -available and would have to be remembered separately. Solaris -introduced a few functions to get this information from the stream -descriptor and these functions are also available in the GNU C library. - - - Function: int __freadable (FILE *STREAM) - The `__freadable' function determines whether the stream STREAM - was opened to allow reading.

For write-only streams the function returns zero. - - This function is declared in `stdio_ext.h'. - - - Function: int __fwritable (FILE *STREAM) - The `__fwritable' function determines whether the stream STREAM - was opened to allow writing.

In this case - the return value is nonzero, otherwise it is zero.

The `fclose' function returns - a value of `0' if the file was closed successfully, and `EOF' if - an error was detected. - - It is important to check for errors when you call `fclose' to close - an output stream, because real, everyday errors can be detected at - this time.

All - buffered data is written and any buffered input is discarded. The - `fcloseall' function returns a value of `0' if all the files were - closed successfully, and `EOF' if an error was detected. - - This function should be used only in special situations, e.g., - when an error occurred and the program must be aborted.

But the programmer must -be aware of a the possible complications. It is important to know about -these also if the program one writes never use threads since the design -and implementation of many stream functions is heavily influenced by the -requirements added by multi-threaded programming. - - The POSIX standard requires that by default the stream operations are -atomic. I.e., issuing two stream operations for the same stream in two -threads at the same time will cause the operations to be executed as if -they were issued sequentially. The buffer operations performed while -reading or writing are protected from other uses of the same stream. To -do this each stream has an internal lock object which has to be -(implicitly) acquired before any work can be done. - - But there are situations where this is not enough and there are also -situations where this is not wanted. The implicit locking is not enough -if the program requires more than one stream function call to happen -atomically. One example would be if an output line a program wants to -generate is created by several function calls. The functions by -themselves would ensure only atomicity of their own operation, but not -atomicity over all the function calls. For this it is necessary to -perform the stream locking in the application code. - - - Function: void flockfile (FILE *STREAM) - The `flockfile' function acquires the internal locking object - associated with the stream STREAM. This ensures that no other - thread can explicitly through `flockfile'/`ftrylockfile' or - implicit through a call of a stream function lock the stream. The - thread will block until the lock is acquired. An explicit call to - `funlockfile' has to be used to release the lock. - - - Function: int ftrylockfile (FILE *STREAM) - The `ftrylockfile' function tries to acquire the internal locking - object associated with the stream STREAM just like `flockfile'. - But unlike `flockfile' this function does not block if the lock is - not available. `ftrylockfile' returns zero if the lock was - successfully acquired. Otherwise the stream is locked by another - thread. - - - Function: void funlockfile (FILE *STREAM) - The `funlockfile' function releases the internal locking object of - the stream STREAM. The stream must have been locked before by a - call to `flockfile' or a successful call of `ftrylockfile'. The - implicit locking performed by the stream operations do not count. - The `funlockfile' function does not return an error status and the - behavior of a call for a stream which is not locked by the current - thread is undefined. - - The following example shows how the functions above can be used to -generate an output line atomically even in multi-threaded applications -(yes, the same job could be done with one `fprintf' call but it is -sometimes not possible): - - FILE *fp; - { - ... - flockfile (fp); - fputs ("This is test number ", fp); - fprintf (fp, "%d\n", test); - funlockfile (fp) - } - - Without the explicit locking it would be possible for another thread -to use the stream FP after the `fputs' call return and before `fprintf' -was called with the result that the number does not follow the word -`number'. - - From this description it might already be clear that the locking -objects in streams are no simple mutexes. Since locking the same -stream twice in the same thread is allowed the locking objects must be -equivalent to recursive mutexes. These mutexes keep track of the owner -and the number of times the lock is acquired. The same number of -`funlockfile' calls by the same threads is necessary to unlock the -stream completely. For instance: - - void - foo (FILE *fp) - { - ftrylockfile (fp); - fputs ("in foo\n", fp); - /* This is very wrong!!! */ - funlockfile (fp); - } - - It is important here that the `funlockfile' function is only called -if the `ftrylockfile' function succeeded in locking the stream. It is -therefore always wrong to ignore the result of `ftrylockfile'. And it -makes no sense since otherwise one would use `flockfile'. The result -of code like that above is that either `funlockfile' tries to free a -stream that hasn't been locked by the current thread or it frees the -stream prematurely. The code should look like this: - - void - foo (FILE *fp) - { - if (ftrylockfile (fp) == 0) - { - fputs ("in foo\n", fp); - funlockfile (fp); - } - } - - Now that we covered why it is necessary to have these locking it is -necessary to talk about situations when locking is unwanted and what can -be done. The locking operations (explicit or implicit) don't come for -free. Even if a lock is not taken the cost is not zero. The operations -which have to be performed require memory operations that are safe in -multi-processor environments. With the many local caches involved in -such systems this is quite costly. So it is best to avoid the locking -completely if it is not needed - because the code in question is never -used in a context where two or more threads may use a stream at a time. -This can be determined most of the time for application code; for -library code which can be used in many contexts one should default to be -conservative and use locking. - - There are two basic mechanisms to avoid locking. The first is to use -the `_unlocked' variants of the stream operations. The POSIX standard -defines quite a few of those and the GNU library adds a few more. -These variants of the functions behave just like the functions with the -name without the suffix except that they do not lock the stream. Using -these functions is very desirable since they are potentially much -faster. This is not only because the locking operation itself is -avoided. More importantly, functions like `putc' and `getc' are very -simple and traditionally (before the introduction of threads) were -implemented as macros which are very fast if the buffer is not empty. -With the addition of locking requirements these functions are no longer -implemented as macros since they would would expand to too much code. -But these macros are still available with the same functionality under -the new names `putc_unlocked' and `getc_unlocked'. This possibly huge -difference of speed also suggests the use of the `_unlocked' functions -even if locking is required. The difference is that the locking then -has to be performed in the program: - - void - foo (FILE *fp, char *buf) - { - flockfile (fp); - while (*buf != '/') - putc_unlocked (*buf++, fp); - funlockfile (fp); - } - - If in this example the `putc' function would be used and the -explicit locking would be missing the `putc' function would have to -acquire the lock in every call, potentially many times depending on when -the loop terminates. Writing it the way illustrated above allows the -`putc_unlocked' macro to be used which means no locking and direct -manipulation of the buffer of the stream. - - A second way to avoid locking is by using a non-standard function -which was introduced in Solaris and is available in the GNU C library -as well. - - - Function: int __fsetlocking (FILE *STREAM, int TYPE) - The `__fsetlocking' function can be used to select whether the - stream operations will implicitly acquire the locking object of the - stream STREAM. By default this is done but it can be disabled and - reinstated using this function. There are three values defined - for the TYPE parameter. - - `FSETLOCKING_INTERNAL' - The stream `stream' will from now on use the default internal - locking. Every stream operation with exception of the - `_unlocked' variants will implicitly lock the stream. - - `FSETLOCKING_BYCALLER' - After the `__fsetlocking' function returns the user is - responsible for locking the stream. None of the stream - operations will implicitly do this anymore until the state is - set back to `FSETLOCKING_INTERNAL'. - - `FSETLOCKING_QUERY' - `__fsetlocking' only queries the current locking state of the - stream. The return value will be `FSETLOCKING_INTERNAL' or - `FSETLOCKING_BYCALLER' depending on the state. - - The return value of `__fsetlocking' is either - `FSETLOCKING_INTERNAL' or `FSETLOCKING_BYCALLER' depending on the - state of the stream before the call. - - This function and the values for the TYPE parameter are declared - in `stdio_ext.h'. - - This function is especially useful when program code has to be used -which is written without knowledge about the `_unlocked' functions (or -if the programmer was too lazy to use them). - - -File: libc.info, Node: Streams and I18N, Next: Simple Output, Prev: Streams and Threads, Up: I/O on Streams - -Streams in Internationalized Applications -========================================= - - ISO C90 introduced the new type `wchar_t' to allow handling larger -character sets. What was missing was a possibility to output strings -of `wchar_t' directly. One had to convert them into multibyte strings -using `mbstowcs' (there was no `mbsrtowcs' yet) and then use the normal -stream functions. While this is doable it is very cumbersome since -performing the conversions is not trivial and greatly increases program -complexity and size. - - The Unix standard early on (I think in XPG4.2) introduced two -additional format specifiers for the `printf' and `scanf' families of -functions. Printing and reading of single wide characters was made -possible using the `%C' specifier and wide character strings can be -handled with `%S'. These modifiers behave just like `%c' and `%s' only -that they expect the corresponding argument to have the wide character -type and that the wide character and string are transformed into/from -multibyte strings before being used. - - This was a beginning but it is still not good enough. Not always is -it desirable to use `printf' and `scanf'. The other, smaller and -faster functions cannot handle wide characters. Second, it is not -possible to have a format string for `printf' and `scanf' consisting of -wide characters. The result is that format strings would have to be -generated if they have to contain non-basic characters. - - In the Amendment 1 to ISO C90 a whole new set of functions was added -to solve the problem. Most of the stream functions got a counterpart -which take a wide character or wide character string instead of a -character or string respectively. The new functions operate on the -same streams (like `stdout'). This is different from the model of the -C++ runtime library where separate streams for wide and normal I/O are -used. - - Being able to use the same stream for wide and normal operations -comes with a restriction: a stream can be used either for wide -operations or for normal operations. Once it is decided there is no -way back. Only a call to `freopen' or `freopen64' can reset the -"orientation". The orientation can be decided in three ways: - - * If any of the normal character functions is used (this includes the - `fread' and `fwrite' functions) the stream is marked as not wide - oriented. - - * If any of the wide character functions is used the stream is - marked as wide oriented. - - * The `fwide' function can be used to set the orientation either way. - - It is important to never mix the use of wide and not wide operations -on a stream. There are no diagnostics issued. The application behavior -will simply be strange or the application will simply crash. The -`fwide' function can help avoiding this. - - - Function: int fwide (FILE *STREAM, int MODE) - The `fwide' function can be used to set and query the state of the - orientation of the stream STREAM. If the MODE parameter has a - positive value the streams get wide oriented, for negative values - narrow oriented. It is not possible to overwrite previous - orientations with `fwide'. I.e., if the stream STREAM was already - oriented before the call nothing is done. - - If MODE is zero the current orientation state is queried and - nothing is changed. - - The `fwide' function returns a negative value, zero, or a positive - value if the stream is narrow, not at all, or wide oriented - respectively. - - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. - - It is generally a good idea to orient a stream as early as possible. -This can prevent surprise especially for the standard streams `stdin', -`stdout', and `stderr'. If some library function in some situations -uses one of these streams and this use orients the stream in a -different way the rest of the application expects it one might end up -with hard to reproduce errors. Remember that no errors are signal if -the streams are used incorrectly. Leaving a stream unoriented after -creation is normally only necessary for library functions which create -streams which can be used in different contexts. - - When writing code which uses streams and which can be used in -different contexts it is important to query the orientation of the -stream before using it (unless the rules of the library interface -demand a specific orientation). The following little, silly function -illustrates this. - - void - print_f (FILE *fp) - { - if (fwide (fp, 0) > 0) - /* Positive return value means wide orientation. */ - fputwc (L'f', fp); - else - fputc ('f', fp); - } - - Note that in this case the function `print_f' decides about the -orientation of the stream if it was unoriented before (will not happen -if the advise above is followed). - - The encoding used for the `wchar_t' values is unspecified and the -user must not make any assumptions about it. For I/O of `wchar_t' -values this means that it is impossible to write these values directly -to the stream. This is not what follows from the ISO C locale model -either. What happens instead is that the bytes read from or written to -the underlying media are first converted into the internal encoding -chosen by the implementation for `wchar_t'. The external encoding is -determined by the `LC_CTYPE' category of the current locale or by the -`ccs' part of the mode specification given to `fopen', `fopen64', -`freopen', or `freopen64'. How and when the conversion happens is -unspecified and it happens invisible to the user. - - Since a stream is created in the unoriented state it has at that -point no conversion associated with it. The conversion which will be -used is determined by the `LC_CTYPE' category selected at the time the -stream is oriented. If the locales are changed at the runtime this -might produce surprising results unless one pays attention.

Suppose you have a -stream reading a file that contains just six characters, the letters -`foobar'. Suppose you have read three characters so far. The -situation looks like this: - - f o o b a r - ^ - -so the next input character will be `b'. - - If instead of reading `b' you unread the letter `o', you get a -situation like this: - - f o o b a r - | - o-- - ^ - -so that the next input characters will be `o' and `b'. - - If you unread `9' instead of `o', you get this situation: - - f o o b a r - | - 9-- - ^ - -so that the next input characters will be `9' and `b'. - - -File: libc.info, Node: How Unread, Prev: Unreading Idea, Up: Unreading - -Using `ungetc' To Do Unreading ------------------------------- - - The function to unread a character is called `ungetc', because it -reverses the action of `getc'. - - - Function: int ungetc (int C, FILE *STREAM) - The `ungetc' function pushes back the character C onto the input - stream STREAM. So the next input from STREAM will read C before - anything else. - - If C is `EOF', `ungetc' does nothing and just returns `EOF'. This - lets you call `ungetc' with the return value of `getc' without - needing to check for an error from `getc'. - - The character that you push back doesn't have to be the same as - the last character that was actually read from the stream. In - fact, it isn't necessary to actually read any characters from the - stream before unreading them with `ungetc'! But that is a strange - way to write a program; usually `ungetc' is used only to unread a - character that was just read from the same stream. The GNU C - library supports this even on files opened in binary mode, but - other systems might not. - - The GNU C library only supports one character of pushback--in other - words, it does not work to call `ungetc' twice without doing input - in between. Other systems might let you push back multiple - characters; then reading from the stream retrieves the characters - in the reverse order that they were pushed. - - Pushing back characters doesn't alter the file; only the internal - buffering for the stream is affected. If a file positioning - function (such as `fseek', `fseeko' or `rewind'; *note File - Positioning::) is called, any pending pushed-back characters are - discarded. - - Unreading a character on a stream that is at end of file clears the - end-of-file indicator for the stream, because it makes the - character of input available. After you read that character, - trying to read again will encounter end of file. - - - Function: wint_t ungetwc (wint_t WC, FILE *STREAM) - The `ungetwc' function behaves just like `ungetc' just that it - pushes back a wide character. - - Here is an example showing the use of `getc' and `ungetc' to skip -over whitespace characters.

Also, for floating-point numbers, -the binary form avoids possible loss of precision in the conversion -process.

This function - returns a value of zero (and doesn't read anything) if either SIZE - or COUNT is zero. - - If `fread' encounters end of file in the middle of an object, it - returns the number of complete objects read, and discards the - partial object.

For example, - - int pct = 37; - char filename[] = "foo.txt"; - printf ("Processing of `%s' is %d%% finished.\nPlease be patient.\n", - filename, pct); - -produces output like - - Processing of `foo.txt' is 37% finished. - Please be patient. - - This example shows the use of the `%d' conversion to specify that an -`int' argument should be printed in decimal notation, the `%s' -conversion to specify printing of a string argument, and the `%%' -conversion to print a literal `%' character. - - There are also conversions for printing an integer argument as an -unsigned value in octal, decimal, or hexadecimal radix (`%o', `%u', or -`%x', respectively); or as a character value (`%c'). - - Floating-point numbers can be printed in normal, fixed-point notation -using the `%f' conversion or in exponential notation using the `%e' -conversion. The `%g' conversion uses either `%e' or `%f' format, -depending on what is more appropriate for the magnitude of the -particular number. - - You can control formatting more precisely by writing "modifiers" -between the `%' and the character that indicates which conversion to -apply. These slightly alter the ordinary behavior of the conversion. -For example, most conversion specifications permit you to specify a -minimum field width and a flag indicating whether you want the result -left- or right-justified within the field. - - The specific flags and modifiers that are permitted and their -interpretation vary depending on the particular conversion. They're all -described in more detail in the following sections. Don't worry if this -all seems excessively complicated at first; you can almost always get -reasonable free-format output without using any of the modifiers at all. -The modifiers are mostly used to make the output look "prettier" in -tables. - - -File: libc.info, Node: Output Conversion Syntax, Next: Table of Output Conversions, Prev: Formatted Output Basics, Up: Formatted Output - -Output Conversion Syntax ------------------------- - - This section provides details about the precise syntax of conversion -specifications that can appear in a `printf' template string. - - Characters in the template string that are not part of a conversion -specification are printed as-is to the output stream. Multibyte -character sequences (*note Character Set Handling::) are permitted in a -template string. - - The conversion specifications in a `printf' template string have the -general form: - - % [ PARAM-NO $] FLAGS WIDTH [ . PRECISION ] TYPE CONVERSION - -or - - % [ PARAM-NO $] FLAGS WIDTH . * [ PARAM-NO $] TYPE CONVERSION - - For example, in the conversion specifier `%-10.8ld', the `-' is a -flag, `10' specifies the field width, the precision is `8', the letter -`l' is a type modifier, and `d' specifies the conversion style. (This -particular type specifier says to print a `long int' argument in -decimal notation, with a minimum of 8 digits left-justified in a field -at least 10 characters wide.) - - In more detail, output conversion specifications consist of an -initial `%' character followed in sequence by: - - * An optional specification of the parameter used for this format. - Normally the parameters to the `printf' function are assigned to - the formats in the order of appearance in the format string. But - in some situations (such as message translation) this is not - desirable and this extension allows an explicit parameter to be - specified. - - The PARAM-NO parts of the format must be integers in the range of - 1 to the maximum number of arguments present to the function call. - Some implementations limit this number to a certainly upper - bound. The exact limit can be retrieved by the following constant. - - - Macro: NL_ARGMAX - The value of `NL_ARGMAX' is the maximum value allowed for the - specification of an positional parameter in a `printf' call. - The actual value in effect at runtime can be retrieved by - using `sysconf' using the `_SC_NL_ARGMAX' parameter *note - Sysconf Definition::. - - Some system have a quite low limit such as 9 for System V - systems. The GNU C library has no real limit. - - If any of the formats has a specification for the parameter - position all of them in the format string shall have one. - Otherwise the behavior is undefined. - - * Zero or more "flag characters" that modify the normal behavior of - the conversion specification. - - * An optional decimal integer specifying the "minimum field width". - If the normal conversion produces fewer characters than this, the - field is padded with spaces to the specified width. This is a - _minimum_ value; if the normal conversion produces more characters - than this, the field is _not_ truncated. Normally, the output is - right-justified within the field. - - You can also specify a field width of `*'. This means that the - next argument in the argument list (before the actual value to be - printed) is used as the field width. The value must be an `int'. - If the value is negative, this means to set the `-' flag (see - below) and to use the absolute value as the field width. - - * An optional "precision" to specify the number of digits to be - written for the numeric conversions. If the precision is - specified, it consists of a period (`.') followed optionally by a - decimal integer (which defaults to zero if omitted). - - You can also specify a precision of `*'. This means that the next - argument in the argument list (before the actual value to be - printed) is used as the precision. The value must be an `int', - and is ignored if it is negative. If you specify `*' for both the - field width and precision, the field width argument precedes the - precision argument. Other C library versions may not recognize - this syntax. - - * An optional "type modifier character", which is used to specify the - data type of the corresponding argument if it differs from the - default type.

Again, the -number of digits following the decimal point is controlled by the -precision. The exponent always contains at least two digits. The `%E' -conversion is similar but the exponent is marked with the letter `E' -instead of `e'. - - The `%g' and `%G' conversions print the argument in the style of -`%e' or `%E' (respectively) if the exponent would be less than -4 or -greater than or equal to the precision; otherwise they use the `%f' -style. A precision of `0', is taken as 1. is Trailing zeros are -removed from the fractional portion of the result and a decimal-point -character appears only if it is followed by a digit. - - The `%a' and `%A' conversions are meant for representing -floating-point numbers exactly in textual form so that they can be -exchanged as texts between different programs and/or machines. The -numbers are represented is the form [`-']`0x'H`.'HHH`p'[`+'|`-']DD. At -the left of the decimal-point character exactly one digit is print. -This character is only `0' if the number is denormalized. Otherwise -the value is unspecified; it is implementation dependent how many bits -are used. The number of hexadecimal digits on the right side of the -decimal-point character is equal to the precision. If the precision is -zero it is determined to be large enough to provide an exact -representation of the number (or it is large enough to distinguish two -adjacent values if the `FLT_RADIX' is not a power of 2, *note Floating -Point Parameters::). For the `%a' conversion lower-case characters are -used to represent the hexadecimal number and the prefix and exponent -sign are printed as `0x' and `p' respectively. Otherwise upper-case -characters are used and `0X' and `P' are used for the representation of -prefix and exponent string. The exponent to the base of two is printed -as a decimal number using at least one digit but at most as many digits -as necessary to represent the value exactly. - - If the value to be printed represents infinity or a NaN, the output -is [`-']`inf' or `nan' respectively if the conversion specifier is -`%a', `%e', `%f', or `%g' and it is [`-']`INF' or `NAN' respectively if -the conversion is `%A', `%E', or `%G'. - - The following flags can be used to modify the behavior: - -`-' - Left-justify the result in the field. Normally the result is - right-justified. - -`+' - Always include a plus or minus sign in the result. - -` ' - If the result doesn't start with a plus or minus sign, prefix it - with a space instead. Since the `+' flag ensures that the result - includes a sign, this flag is ignored if you supply both of them. - -`#' - Specifies that the result should always include a decimal point, - even if no digits follow it. For the `%g' and `%G' conversions, - this also forces trailing zeros after the decimal point to be left - in place where they would otherwise be removed. - -`'' - Separate the digits of the integer part of the result into groups - as specified by the locale specified for the `LC_NUMERIC' category; - *note General Numeric::. This flag is a GNU extension. - -`0' - Pad the field with zeros instead of spaces; the zeros are placed - after any sign. This flag is ignored if the `-' flag is also - specified. - - The precision specifies how many digits follow the decimal-point -character for the `%f', `%e', and `%E' conversions. For these -conversions, the default precision is `6'. If the precision is -explicitly `0', this suppresses the decimal point character entirely. -For the `%g' and `%G' conversions, the precision specifies how many -significant digits to print. Significant digits are the first digit -before the decimal point, and all the digits after it. If the -precision is `0' or not specified for `%g' or `%G', it is treated like -a value of `1'. If the value being printed cannot be expressed -accurately in the specified number of digits, the value is rounded to -the nearest number that fits. - - Without a type modifier, the floating-point conversions use an -argument of type `double'. (By the default argument promotions, any -`float' arguments are automatically converted to `double'.) The -following type modifier is supported: - -`L' - An uppercase `L' specifies that the argument is a `long double'. - - Here are some examples showing how numbers print using the various -floating-point conversions.

In case there is no -`l' modifier the `int' argument is first converted to an `unsigned -char'. Then, if used in a wide stream function, the character is -converted into the corresponding wide character. The `-' flag can be -used to specify left-justification in the field, but no other flags are -defined, and no precision or type modifier can be given. For example: - - printf ("%c%c%c%c%c", 'h', 'e', 'l', 'l', 'o'); - -prints `hello'. - - If there is a `l' modifier present the argument is expected to be of -type `wint_t'. If used in a multibyte function the wide character is -converted into a multibyte character before being added to the output. -In this case more than one output byte can be produced. - - The `%s' conversion prints a string. If no `l' modifier is present -the corresponding argument must be of type `char *' (or `const char -*'). If used in a wide stream function the string is first converted -in a wide character string. A precision can be specified to indicate -the maximum number of characters to write; otherwise characters in the -string up to but not including the terminating null character are -written to the output stream. The `-' flag can be used to specify -left-justification in the field, but no other flags or type modifiers -are defined for this conversion. For example: - - printf ("%3s%-6s", "no", "where"); - -prints ` nowhere '. - - If there is a `l' modifier present the argument is expected to be of -type `wchar_t' (or `const wchar_t *'). - - If you accidentally pass a null pointer as the argument for a `%s' -conversion, the GNU library prints it as `(null)'. We think this is -more useful than crashing. But it's not good practice to pass a null -argument intentionally. - - The `%m' conversion prints the string corresponding to the error -code in `errno'. *Note Error Messages::. Thus: - - fprintf (stderr, "can't open `%s': %m\n", filename); - -is equivalent to: - - fprintf (stderr, "can't open `%s': %s\n", filename, strerror (errno)); - -The `%m' conversion is a GNU C library extension. - - The `%p' conversion prints a pointer value. The corresponding -argument must be of type `void *'. In practice, you can use any type -of pointer. - - In the GNU system, non-null pointers are printed as unsigned -integers, as if a `%#x' conversion were used. Null pointers print as -`(nil)'. (Pointers might print differently in other systems.) - - For example: - - printf ("%p", "testing"); - -prints `0x' followed by a hexadecimal number--the address of the string -constant `"testing"'. It does not print the word `testing'. - - You can supply the `-' flag with the `%p' conversion to specify -left-justification, but no other flags, precision, or type modifiers -are defined. - - The `%n' conversion is unlike any of the other output conversions. -It uses an argument which must be a pointer to an `int', but instead of -printing anything it stores the number of characters printed so far by -this call at that location. The `h' and `l' type modifiers are -permitted to specify that the argument is of type `short int *' or -`long int *' instead of `int *', but no flags, field width, or -precision are permitted. - - For example, - - int nchar; - printf ("%d %s%n\n", 3, "bears", &nchar); - -prints: - - 3 bears - -and sets `nchar' to `7', because `3 bears' is seven characters. - - The `%%' conversion prints a literal `%' character.

A null - character is written to mark the end of the string. - - The `sprintf' function returns the number of characters stored in - the array S, not including the terminating null character. - - The behavior of this function is undefined if copying takes place - between objects that overlap--for example, if S is also given as - an argument to be printed under control of the `%s' conversion. - *Note Copying and Concatenation::. - - *Warning:* The `sprintf' function can be *dangerous* because it - can potentially output more characters than can fit in the - allocation size of the string S. Remember that the field width - given in a conversion specification is only a _minimum_ value. - - To avoid this problem, you can use `snprintf' or `asprintf', - described below. - - - Function: int swprintf (wchar_t *S, size_t SIZE, const wchar_t - *TEMPLATE, ...) - This is like `wprintf', except that the output is stored in the - wide character array WS instead of written to a stream. A null - wide character is written to mark the end of the string. The SIZE - argument specifies the maximum number of characters to produce. - The trailing null character is counted towards this limit, so you - should allocate at least SIZE wide characters for the string WS. - - The return value is the number of characters generated for the - given input, excluding the trailing null. If not all output fits - into the provided buffer a negative value is returned. You should - try again with a bigger output string. _Note:_ this is different - from how `snprintf' handles this situation. - - Note that the corresponding narrow stream function takes fewer - parameters. `swprintf' in fact corresponds to the `snprintf' - function. Since the `sprintf' function can be dangerous and should - be avoided the ISO C committee refused to make the same mistake - again and decided to not define an function exactly corresponding - to `sprintf'. - - - Function: int snprintf (char *S, size_t SIZE, const char *TEMPLATE, - ...) - The `snprintf' function is similar to `sprintf', except that the - SIZE argument specifies the maximum number of characters to - produce. The trailing null character is counted towards this - limit, so you should allocate at least SIZE characters for the - string S. - - The return value is the number of characters which would be - generated for the given input, excluding the trailing null. If - this value is greater or equal to SIZE, not all characters from - the result have been stored in S. You should try again with a - bigger output string. Here is an example of doing this: - - /* Construct a message describing the value of a variable - whose name is NAME and whose value is VALUE. */ - char * - make_message (char *name, char *value) - { - /* Guess we need no more than 100 chars of space. */ - int size = 100; - char *buffer = (char *) xmalloc (size); - int nchars; - if (buffer == NULL) - return NULL; - - /* Try to print in the allocated space. */ - nchars = snprintf (buffer, size, "value of %s is %s", - name, value); - if (nchars >= size) - { - /* Reallocate buffer now that we know - how much space is needed. */ - buffer = (char *) xrealloc (buffer, nchars + 1); - - if (buffer != NULL) - /* Try again. */ - snprintf (buffer, size, "value of %s is %s", - name, value); - } - /* The last call worked, return the string. */ - return buffer; - } - - In practice, it is often easier just to use `asprintf', below. - - *Attention:* In versions of the GNU C library prior to 2.1 the - return value is the number of characters stored, not including the - terminating null; unless there was not enough space in S to store - the result in which case `-1' is returned.

But there is no way to do -this in C, and it would be hard to provide a way, since at the C -language level there is no way to tell how many arguments your function -received. - - Since that method is impossible, we provide alternative functions, -the `vprintf' series, which lets you pass a `va_list' to describe "all -of my arguments after the first five." - - When it is sufficient to define a macro rather than a real function, -the GNU C compiler provides a way to do this much more easily with -macros. For example: - - #define myprintf(a, b, c, d, e, rest...) \ - printf (mytemplate , ## rest) - -*Note Macros with Variable Numbers of Arguments: (gcc.info)Macro -Varargs, for details. But this is limited to macros, and does not -apply to real functions at all. - - Before calling `vprintf' or the other functions listed in this -section, you _must_ call `va_start' (*note Variadic Functions::) to -initialize a pointer to the variable arguments. Then you can call -`va_arg' to fetch the arguments that you want to handle yourself. This -advances the pointer past those arguments. - - Once your `va_list' pointer is pointing at the argument of your -choice, you are ready to call `vprintf'. That argument and all -subsequent arguments that were passed to your function are used by -`vprintf' along with the template that you specified separately. - - In some other systems, the `va_list' pointer may become invalid -after the call to `vprintf', so you must not use `va_arg' after you -call `vprintf'. Instead, you should call `va_end' to retire the -pointer from service.

Calling `vprintf' does not destroy the argument list of -your function, merely the particular pointer that you passed to it. - - GNU C does not have such restrictions. You can safely continue to -fetch arguments from a `va_list' pointer after passing it to `vprintf', -and `va_end' is a no-op.

For - example, `PA_INT|PA_FLAG_PTR' represents the type `int *'. - -`PA_FLAG_SHORT' - If this bit is set, it indicates that the base type is modified - with `short'.

While the syntax of the conversion specifications in the -template is very similar to that for `printf', the interpretation of -the template is oriented more towards free-format input and simple -pattern matching, rather than fixed-field formatting. For example, -most `scanf' conversions skip over any amount of "white space" -(including spaces, tabs, and newlines) in the input file, and there is -no concept of precision for the numeric input conversions as there is -for the corresponding output conversions. Ordinarily, non-whitespace -characters in the template are expected to match characters in the -input stream exactly, but a matching failure is distinct from an input -error on the stream. - - Another area of difference between `scanf' and `printf' is that you -must remember to supply pointers rather than immediate values as the -optional arguments to `scanf'; the values that are read are stored in -the objects that the pointers point to. Even experienced programmers -tend to forget this occasionally, so if your program is getting strange -errors that seem to be related to `scanf', you might want to -double-check this. - - When a "matching failure" occurs, `scanf' returns immediately, -leaving the first non-matching character as the next character to be -read from the stream. The normal return value from `scanf' is the -number of values that were assigned, so you can use this to determine if -a matching error happened before all the expected values were read. - - The `scanf' function is typically used for things like reading in -the contents of tables. For example, here is a function that uses -`scanf' to initialize an array of `double': - - void - readarray (double *array, int n) - { - int i; - for (i=0; i scanf ("%a[a-zA-Z0-9] = %a[^\n]\n", - &variable, &value)) - { - invalid_input_error (); - return 0; - } - - ... - } - - -File: libc.info, Node: Other Input Conversions, Next: Formatted Input Functions, Prev: Dynamic String Input, Up: Formatted Input - -Other Input Conversions ------------------------ - - This section describes the miscellaneous input conversions. - - The `%p' conversion is used to read a pointer value. It recognizes -the same syntax used by the `%p' output conversion for `printf' (*note -Other Output Conversions::); that is, a hexadecimal number just as the -`%x' conversion accepts. The corresponding argument should be of type -`void **'; that is, the address of a place to store a pointer. - - The resulting pointer value is not guaranteed to be valid if it was -not originally written during the same program execution that reads it -in. - - The `%n' conversion produces the number of characters read so far by -this call. The corresponding argument should be of type `int *'. This -conversion works in the same way as the `%n' conversion for `printf'; -see *Note Other Output Conversions::, for an example. - - The `%n' conversion is the only mechanism for determining the -success of literal matches or conversions with suppressed assignments. -If the `%n' follows the locus of a matching failure, then no value is -stored for it since `scanf' returns before processing the `%n'. If you -store `-1' in that argument slot before calling `scanf', the presence -of `-1' after `scanf' indicates an error occurred before the `%n' was -reached. - - Finally, the `%%' conversion matches a literal `%' character in the -input stream, without using an argument. This conversion does not -permit any flags, field width, or type modifier to be specified. - - -File: libc.info, Node: Formatted Input Functions, Next: Variable Arguments Input, Prev: Other Input Conversions, Up: Formatted Input - -Formatted Input Functions -------------------------- - - Here are the descriptions of the functions for performing formatted -input. Prototypes for these functions are in the header file `stdio.h'. - - - Function: int scanf (const char *TEMPLATE, ...) - The `scanf' function reads formatted input from the stream `stdin' - under the control of the template string TEMPLATE. The optional - arguments are pointers to the places which receive the resulting - values. - - The return value is normally the number of successful assignments. - If an end-of-file condition is detected before any matches are - performed, including matches against whitespace and literal - characters in the template, then `EOF' is returned. - - - Function: int wscanf (const wchar_t *TEMPLATE, ...) - The `wscanf' function reads formatted input from the stream - `stdin' under the control of the template string TEMPLATE. The - optional arguments are pointers to the places which receive the - resulting values. - - The return value is normally the number of successful assignments. - If an end-of-file condition is detected before any matches are - performed, including matches against whitespace and literal - characters in the template, then `WEOF' is returned. - - - Function: int fscanf (FILE *STREAM, const char *TEMPLATE, ...) - This function is just like `scanf', except that the input is read - from the stream STREAM instead of `stdin'. - - - Function: int fwscanf (FILE *STREAM, const wchar_t *TEMPLATE, ...) - This function is just like `wscanf', except that the input is read - from the stream STREAM instead of `stdin'. - - - Function: int sscanf (const char *S, const char *TEMPLATE, ...) - This is like `scanf', except that the characters are taken from the - null-terminated string S instead of from a stream.

These functions check -indicators that are part of the internal state of the stream object, -indicators set if the appropriate condition was detected by a previous -I/O operation on that stream. - - - Macro: int EOF - This macro is an integer value that is returned by a number of - narrow stream functions to indicate an end-of-file condition, or - some other error situation. With the GNU library, `EOF' is `-1'. - In other libraries, its value may be some other negative number. - - This symbol is declared in `stdio.h'. - - - Macro: int WEOF - This macro is an integer value that is returned by a number of wide - stream functions to indicate an end-of-file condition, or some - other error situation. With the GNU library, `WEOF' is `-1'. In - other libraries, its value may be some other negative number. - - This symbol is declared in `wchar.h'. - - - Function: int feof (FILE *STREAM) - The `feof' function returns nonzero if and only if the end-of-file - indicator for the stream STREAM is set. - - This symbol is declared in `stdio.h'. - - - Function: int feof_unlocked (FILE *STREAM) - The `feof_unlocked' function is equivalent to the `feof' function - except that it does not implicitly lock the stream. - - This function is a GNU extension. - - This symbol is declared in `stdio.h'. - - - Function: int ferror (FILE *STREAM) - The `ferror' function returns nonzero if and only if the error - indicator for the stream STREAM is set, indicating that an error - has occurred on a previous operation on the stream. - - This symbol is declared in `stdio.h'. - - - Function: int ferror_unlocked (FILE *STREAM) - The `ferror_unlocked' function is equivalent to the `ferror' - function except that it does not implicitly lock the stream. - - This function is a GNU extension. - - This symbol is declared in `stdio.h'. - - In addition to setting the error indicator associated with the -stream, the functions that operate on streams also set `errno' in the -same way as the corresponding low-level functions that operate on file -descriptors. For example, all of the functions that perform output to a -stream--such as `fputc', `printf', and `fflush'--are implemented in -terms of `write', and all of the `errno' error conditions defined for -`write' are meaningful for these functions.

In both cases, you should seek to a known -position before retrying. - - Most errors that can happen are not recoverable -- a second try will -always fail again in the same way. So usually it is best to give up and -report the error to the user, rather than install complicated recovery -logic. - - One important exception is `EINTR' (*note Interrupted Primitives::). -Many stream I/O implementations will treat it as an ordinary error, -which can be quite inconvenient. You can avoid this hassle by -installing all signals with the `SA_RESTART' flag. - - For similar reasons, setting nonblocking I/O on a stream's file -descriptor is not usually advisable. - - -File: libc.info, Node: Binary Streams, Next: File Positioning, Prev: Error Recovery, Up: I/O on Streams - -Text and Binary Streams -======================= - - The GNU system and other POSIX-compatible operating systems organize -all files as uniform sequences of characters. However, some other -systems make a distinction between files containing text and files -containing binary data, and the input and output facilities of ISO C -provide for this distinction. This section tells you how to write -programs portable to such systems. - - When you open a stream, you can specify either a "text stream" or a -"binary stream". You indicate that you want a binary stream by -specifying the `b' modifier in the OPENTYPE argument to `fopen'; see -*Note Opening Streams::. Without this option, `fopen' opens the file -as a text stream. - - Text and binary streams differ in several ways: - - * The data read from a text stream is divided into "lines" which are - terminated by newline (`'\n'') characters, while a binary stream is - simply a long series of characters. A text stream might on some - systems fail to handle lines more than 254 characters long - (including the terminating newline character). - - * On some systems, text files can contain only printing characters, - horizontal tab characters, and newlines, and so text streams may - not support other characters. However, binary streams can handle - any character value. - - * Space characters that are written immediately preceding a newline - character in a text stream may disappear when the file is read in - again. - - * More generally, there need not be a one-to-one mapping between - characters that are read from or written to a text stream, and the - characters in the actual file. - - Since a binary stream is always more capable and more predictable -than a text stream, you might wonder what purpose text streams serve. -Why not simply always use binary streams? The answer is that on these -operating systems, text and binary streams use different file formats, -and the only way to read or write "an ordinary file of text" that can -work with other text-oriented programs is through a text stream. - - In the GNU library, and on all POSIX systems, there is no difference -between text streams and binary streams. When you open a stream, you -get the same kind of stream regardless of whether you ask for binary. -This stream can handle any file content, and has none of the -restrictions that text streams sometimes have. - - -File: libc.info, Node: File Positioning, Next: Portable Positioning, Prev: Binary Streams, Up: I/O on Streams - -File Positioning -================ - - The "file position" of a stream describes where in the file the -stream is currently reading or writing. I/O on the stream advances the -file position through the file. In the GNU system, the file position is -represented as an integer, which counts the number of bytes from the -beginning of the file. *Note File Position::. - - During I/O to an ordinary disk file, you can change the file position -whenever you wish, so as to read or write any portion of the file. Some -other kinds of files may also permit this. Files which support changing -the file position are sometimes referred to as "random-access" files. - - You can use the functions in this section to examine or modify the -file position indicator associated with a stream. The symbols listed -below are declared in the header file `stdio.h'. - - - Function: long int ftell (FILE *STREAM) - This function returns the current file position of the stream - STREAM. - - This function can fail if the stream doesn't support file - positioning, or if the file position can't be represented in a - `long int', and possibly for other reasons as well. If a failure - occurs, a value of `-1' is returned. - - - Function: off_t ftello (FILE *STREAM) - The `ftello' function is similar to `ftell', except that it - returns a value of type `off_t'. Systems which support this type - use it to describe all file positions, unlike the POSIX - specification which uses a long int. The two are not necessarily - the same size. Therefore, using ftell can lead to problems if the - implementation is written on top of a POSIX compliant low-level - I/O implementation, and using `ftello' is preferable whenever it - is available. - - If this function fails it returns `(off_t) -1'. This can happen - due to missing support for file positioning or internal errors. - Otherwise the return value is the current file position. - - The function is an extension defined in the Unix Single - Specification version 2. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32 bit system this function is in fact `ftello64'. I.e., the LFS - interface transparently replaces the old interface. - - - Function: off64_t ftello64 (FILE *STREAM) - This function is similar to `ftello' with the only difference that - the return value is of type `off64_t'. This also requires that the - stream STREAM was opened using either `fopen64', `freopen64', or - `tmpfile64' since otherwise the underlying file operations to - position the file pointer beyond the 2^31 bytes limit might fail. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `ftello' - and so transparently replaces the old interface. - - - Function: int fseek (FILE *STREAM, long int OFFSET, int WHENCE) - The `fseek' function is used to change the file position of the - stream STREAM. The value of WHENCE must be one of the constants - `SEEK_SET', `SEEK_CUR', or `SEEK_END', to indicate whether the - OFFSET is relative to the beginning of the file, the current file - position, or the end of the file, respectively. - - This function returns a value of zero if the operation was - successful, and a nonzero value to indicate failure. A successful - call also clears the end-of-file indicator of STREAM and discards - any characters that were "pushed back" by the use of `ungetc'. - - `fseek' either flushes any buffered output before setting the file - position or else remembers it so it will be written later in its - proper place in the file. - - - Function: int fseeko (FILE *STREAM, off_t OFFSET, int WHENCE) - This function is similar to `fseek' but it corrects a problem with - `fseek' in a system with POSIX types. Using a value of type `long - int' for the offset is not compatible with POSIX. `fseeko' uses - the correct type `off_t' for the OFFSET parameter. - - For this reason it is a good idea to prefer `ftello' whenever it is - available since its functionality is (if different at all) closer - the underlying definition. - - The functionality and return value is the same as for `fseek'. - - The function is an extension defined in the Unix Single - Specification version 2. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32 bit system this function is in fact `fseeko64'. I.e., the LFS - interface transparently replaces the old interface. - - - Function: int fseeko64 (FILE *STREAM, off64_t OFFSET, int WHENCE) - This function is similar to `fseeko' with the only difference that - the OFFSET parameter is of type `off64_t'. This also requires - that the stream STREAM was opened using either `fopen64', - `freopen64', or `tmpfile64' since otherwise the underlying file - operations to position the file pointer beyond the 2^31 bytes - limit might fail. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `fseeko' - and so transparently replaces the old interface. - - *Portability Note:* In non-POSIX systems, `ftell', `ftello', `fseek' -and `fseeko' might work reliably only on binary streams. *Note Binary -Streams::. - - The following symbolic constants are defined for use as the WHENCE -argument to `fseek'. They are also used with the `lseek' function -(*note I/O Primitives::) and to specify offsets for file locks (*note -Control Operations::). - - - Macro: int SEEK_SET - This is an integer constant which, when used as the WHENCE - argument to the `fseek' or `fseeko' function, specifies that the - offset provided is relative to the beginning of the file. - - - Macro: int SEEK_CUR - This is an integer constant which, when used as the WHENCE - argument to the `fseek' or `fseeko' function, specifies that the - offset provided is relative to the current file position. - - - Macro: int SEEK_END - This is an integer constant which, when used as the WHENCE - argument to the `fseek' or `fseeko' function, specifies that the - offset provided is relative to the end of the file. - - - Function: void rewind (FILE *STREAM) - The `rewind' function positions the stream STREAM at the beginning - of the file. It is equivalent to calling `fseek' or `fseeko' on - the STREAM with an OFFSET argument of `0L' and a WHENCE argument - of `SEEK_SET', except that the return value is discarded and the - error indicator for the stream is reset. - - These three aliases for the `SEEK_...' constants exist for the sake -of compatibility with older BSD systems. They are defined in two -different header files: `fcntl.h' and `sys/file.h'. - -`L_SET' - An alias for `SEEK_SET'. - -`L_INCR' - An alias for `SEEK_CUR'. - -`L_XTND' - An alias for `SEEK_END'. - diff -u -udbrN glibc-2.3.2/manual/libc.info-2 glibc-2.3.2-200304020432/manual/libc.info-2 --- glibc-2.3.2/manual/libc.info-2 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-2 Thu Jan 1 01:00:00 1970 @@ -1,1004 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

Specifically, familiarity with ISO standard C (*note ISO -C::), rather than "traditional" pre-ISO C dialects, is assumed. - - The GNU C library includes several "header files", each of which -provides definitions and declarations for a group of related facilities; -this information is used by the C compiler when processing your program. -For example, the header file `stdio.h' declares facilities for -performing input and output, and the header file `string.h' declares -string processing utilities. The organization of this manual generally -follows the same division as the header files. - - If you are reading this manual for the first time, you should read -all of the introductory material and skim the remaining chapters. -There are a _lot_ of functions in the GNU C library and it's not -realistic to expect that you will be able to remember exactly _how_ to -use each and every one of them. It's more important to become -generally familiar with the kinds of facilities that the library -provides, so that when you are writing your programs you can recognize -_when_ to make use of library functions, and _where_ in this manual you -can find more specific information about them. - - -File: libc.info, Node: Standards and Portability, Next: Using the Library, Prev: Getting Started, Up: Introduction - -Standards and Portability -========================= - - This section discusses the various standards and other sources that -the GNU C library is based upon. These sources include the ISO C and -POSIX standards, and the System V and Berkeley Unix implementations. - - The primary focus of this manual is to tell you how to make effective -use of the GNU library facilities. But if you are concerned about -making your programs compatible with these standards, or portable to -operating systems other than GNU, this can affect how you use the -library. This section gives you an overview of these standards, so that -you will know what they are when they are mentioned in other parts of -the manual. - - *Note Library Summary::, for an alphabetical list of the functions -and other symbols provided by the library. This list also states which -standards each function or symbol comes from. - -* Menu: - -* ISO C:: The international standard for the C - programming language. -* POSIX:: The ISO/IEC 9945 (aka IEEE 1003) standards - for operating systems. -* Berkeley Unix:: BSD and SunOS. -* SVID:: The System V Interface Description. -* XPG:: The X/Open Portability Guide. - - -File: libc.info, Node: ISO C, Next: POSIX, Up: Standards and Portability - -ISO C ------ - - The GNU C library is compatible with the C standard adopted by the -American National Standards Institute (ANSI): `American National -Standard X3.159-1989--"ANSI C"' and later by the International -Standardization Organization (ISO): `ISO/IEC 9899:1990, "Programming -languages--C"'. We here refer to the standard as ISO C since this is -the more general standard in respect of ratification. The header files -and library facilities that make up the GNU library are a superset of -those specified by the ISO C standard. - - If you are concerned about strict adherence to the ISO C standard, -you should use the `-ansi' option when you compile your programs with -the GNU C compiler. This tells the compiler to define _only_ ISO -standard features from the library header files, unless you explicitly -ask for additional features. *Note Feature Test Macros::, for -information on how to do this. - - Being able to restrict the library to include only ISO C features is -important because ISO C puts limitations on what names can be defined -by the library implementation, and the GNU extensions don't fit these -limitations. *Note Reserved Names::, for more information about these -restrictions. - - This manual does not attempt to give you complete details on the -differences between ISO C and older dialects. It gives advice on how -to write programs to work portably under multiple C dialects, but does -not aim for completeness. - - -File: libc.info, Node: POSIX, Next: Berkeley Unix, Prev: ISO C, Up: Standards and Portability - -POSIX (The Portable Operating System Interface) ------------------------------------------------ - - The GNU library is also compatible with the ISO "POSIX" family of -standards, known more formally as the "Portable Operating System -Interface for Computer Environments" (ISO/IEC 9945). They were also -published as ANSI/IEEE Std 1003. POSIX is derived mostly from various -versions of the Unix operating system. - - The library facilities specified by the POSIX standards are a -superset of those required by ISO C; POSIX specifies additional -features for ISO C functions, as well as specifying new additional -functions. In general, the additional requirements and functionality -defined by the POSIX standards are aimed at providing lower-level -support for a particular kind of operating system environment, rather -than general programming language support which can run in many diverse -operating system environments. - - The GNU C library implements all of the functions specified in -`ISO/IEC 9945-1:1996, the POSIX System Application Program Interface', -commonly referred to as POSIX.1. The primary extensions to the ISO C -facilities specified by this standard include file system interface -primitives (*note File System Interface::), device-specific terminal -control functions (*note Low-Level Terminal Interface::), and process -control functions (*note Processes::). - - Some facilities from `ISO/IEC 9945-2:1993, the POSIX Shell and -Utilities standard' (POSIX.2) are also implemented in the GNU library. -These include utilities for dealing with regular expressions and other -pattern matching facilities (*note Pattern Matching::). - - -File: libc.info, Node: Berkeley Unix, Next: SVID, Prev: POSIX, Up: Standards and Portability - -Berkeley Unix -------------- - - The GNU C library defines facilities from some versions of Unix which -are not formally standardized, specifically from the 4.2 BSD, 4.3 BSD, -and 4.4 BSD Unix systems (also known as "Berkeley Unix") and from -"SunOS" (a popular 4.2 BSD derivative that includes some Unix System V -functionality). These systems support most of the ISO C and POSIX -facilities, and 4.4 BSD and newer releases of SunOS in fact support -them all. - - The BSD facilities include symbolic links (*note Symbolic Links::), -the `select' function (*note Waiting for I/O::), the BSD signal -functions (*note BSD Signal Handling::), and sockets (*note Sockets::). - - -File: libc.info, Node: SVID, Next: XPG, Prev: Berkeley Unix, Up: Standards and Portability - -SVID (The System V Interface Description) ------------------------------------------ - - The "System V Interface Description" (SVID) is a document describing -the AT&T Unix System V operating system. It is to some extent a -superset of the POSIX standard (*note POSIX::). - - The GNU C library defines most of the facilities required by the SVID -that are not also required by the ISO C or POSIX standards, for -compatibility with System V Unix and other Unix systems (such as -SunOS) which include these facilities. However, many of the more -obscure and less generally useful facilities required by the SVID are -not included. (In fact, Unix System V itself does not provide them -all.) - - The supported facilities from System V include the methods for -inter-process communication and shared memory, the `hsearch' and -`drand48' families of functions, `fmtmsg' and several of the -mathematical functions. - - -File: libc.info, Node: XPG, Prev: SVID, Up: Standards and Portability - -XPG (The X/Open Portability Guide) ----------------------------------- - - The X/Open Portability Guide, published by the X/Open Company, Ltd., -is a more general standard than POSIX. X/Open owns the Unix copyright -and the XPG specifies the requirements for systems which are intended -to be a Unix system. - - The GNU C library complies to the X/Open Portability Guide, Issue -4.2, with all extensions common to XSI (X/Open System Interface) -compliant systems and also all X/Open UNIX extensions. - - The additions on top of POSIX are mainly derived from functionality -available in System V and BSD systems. Some of the really bad mistakes -in System V systems were corrected, though. Since fulfilling the XPG -standard with the Unix extensions is a precondition for getting the -Unix brand chances are good that the functionality is available on -commercial systems. - - -File: libc.info, Node: Using the Library, Next: Roadmap to the Manual, Prev: Standards and Portability, Up: Introduction - -Using the Library -================= - - This section describes some of the practical issues involved in using -the GNU C library. - -* Menu: - -* Header Files:: How to include the header files in your - programs. -* Macro Definitions:: Some functions in the library may really - be implemented as macros. -* Reserved Names:: The C standard reserves some names for - the library, and some for users. -* Feature Test Macros:: How to control what names are defined. - - -File: libc.info, Node: Header Files, Next: Macro Definitions, Up: Using the Library - -Header Files ------------- - - Libraries for use by C programs really consist of two parts: "header -files" that define types and macros and declare variables and -functions; and the actual library or "archive" that contains the -definitions of the variables and functions. - - (Recall that in C, a "declaration" merely provides information that -a function or variable exists and gives its type. For a function -declaration, information about the types of its arguments might be -provided as well. The purpose of declarations is to allow the compiler -to correctly process references to the declared variables and functions. -A "definition", on the other hand, actually allocates storage for a -variable or says what a function does.) - - In order to use the facilities in the GNU C library, you should be -sure that your program source files include the appropriate header -files. This is so that the compiler has declarations of these -facilities available and can correctly process references to them. -Once your program has been compiled, the linker resolves these -references to the actual definitions provided in the archive file. - - Header files are included into a program source file by the -`#include' preprocessor directive. The C language supports two forms -of this directive; the first, - - #include "HEADER" - -is typically used to include a header file HEADER that you write -yourself; this would contain definitions and declarations describing the -interfaces between the different parts of your particular application. -By contrast, - - #include - -is typically used to include a header file `file.h' that contains -definitions and declarations for a standard library. This file would -normally be installed in a standard place by your system administrator. -You should use this second form for the C library header files. - - Typically, `#include' directives are placed at the top of the C -source file, before any other code. If you begin your source files with -some comments explaining what the code in the file does (a good idea), -put the `#include' directives immediately afterwards, following the -feature test macro definition (*note Feature Test Macros::). - - For more information about the use of header files and `#include' -directives, *note Header Files: (cpp.info)Header Files.. - - The GNU C library provides several header files, each of which -contains the type and macro definitions and variable and function -declarations for a group of related facilities. This means that your -programs may need to include several header files, depending on exactly -which facilities you are using. - - Some library header files include other library header files -automatically. However, as a matter of programming style, you should -not rely on this; it is better to explicitly include all the header -files required for the library facilities you are using. The GNU C -library header files have been written in such a way that it doesn't -matter if a header file is accidentally included more than once; -including a header file a second time has no effect. Likewise, if your -program needs to include multiple header files, the order in which they -are included doesn't matter. - - *Compatibility Note:* Inclusion of standard header files in any -order and any number of times works in any ISO C implementation. -However, this has traditionally not been the case in many older C -implementations. - - Strictly speaking, you don't _have to_ include a header file to use -a function it declares; you could declare the function explicitly -yourself, according to the specifications in this manual. But it is -usually better to include the header file because it may define types -and macros that are not otherwise available and because it may define -more efficient macro replacements for some functions. It is also a sure -way to have the correct declaration. - - -File: libc.info, Node: Macro Definitions, Next: Reserved Names, Prev: Header Files, Up: Using the Library - -Macro Definitions of Functions ------------------------------- - - If we describe something as a function in this manual, it may have a -macro definition as well. This normally has no effect on how your -program runs--the macro definition does the same thing as the function -would. In particular, macro equivalents for library functions evaluate -arguments exactly once, in the same way that a function call would. The -main reason for these macro definitions is that sometimes they can -produce an inline expansion that is considerably faster than an actual -function call. - - Taking the address of a library function works even if it is also -defined as a macro. This is because, in this context, the name of the -function isn't followed by the left parenthesis that is syntactically -necessary to recognize a macro call. - - You might occasionally want to avoid using the macro definition of a -function--perhaps to make your program easier to debug. There are two -ways you can do this: - - * You can avoid a macro definition in a specific use by enclosing - the name of the function in parentheses. This works because the - name of the function doesn't appear in a syntactic context where - it is recognizable as a macro call. - - * You can suppress any macro definition for a whole source file by - using the `#undef' preprocessor directive, unless otherwise stated - explicitly in the description of that facility. - - For example, suppose the header file `stdlib.h' declares a function -named `abs' with - - extern int abs (int); - -and also provides a macro definition for `abs'. Then, in: - - #include - int f (int *i) { return abs (++*i); } - -the reference to `abs' might refer to either a macro or a function. On -the other hand, in each of the following examples the reference is to a -function and not a macro. - - #include - int g (int *i) { return (abs) (++*i); } - - #undef abs - int h (int *i) { return abs (++*i); } - - Since macro definitions that double for a function behave in exactly -the same way as the actual function version, there is usually no need -for any of these methods. In fact, removing macro definitions usually -just makes your program slower. - - -File: libc.info, Node: Reserved Names, Next: Feature Test Macros, Prev: Macro Definitions, Up: Using the Library - -Reserved Names --------------- - - The names of all library types, macros, variables and functions that -come from the ISO C standard are reserved unconditionally; your program -*may not* redefine these names. All other library names are reserved -if your program explicitly includes the header file that defines or -declares them. There are several reasons for these restrictions: - - * Other people reading your code could get very confused if you were - using a function named `exit' to do something completely different - from what the standard `exit' function does, for example. - Preventing this situation helps to make your programs easier to - understand and contributes to modularity and maintainability. - - * It avoids the possibility of a user accidentally redefining a - library function that is called by other library functions. If - redefinition were allowed, those other functions would not work - properly. - - * It allows the compiler to do whatever special optimizations it - pleases on calls to these functions, without the possibility that - they may have been redefined by the user. Some library - facilities, such as those for dealing with variadic arguments - (*note Variadic Functions::) and non-local exits (*note Non-Local - Exits::), actually require a considerable amount of cooperation on - the part of the C compiler, and with respect to the - implementation, it might be easier for the compiler to treat these - as built-in parts of the language. - - In addition to the names documented in this manual, reserved names -include all external identifiers (global functions and variables) that -begin with an underscore (`_') and all identifiers regardless of use -that begin with either two underscores or an underscore followed by a -capital letter are reserved names. This is so that the library and -header files can define functions, variables, and macros for internal -purposes without risk of conflict with names in user programs. - - Some additional classes of identifier names are reserved for future -extensions to the C language or the POSIX.1 environment. While using -these names for your own purposes right now might not cause a problem, -they do raise the possibility of conflict with future versions of the C -or POSIX standards, so you should avoid these names. - - * Names beginning with a capital `E' followed a digit or uppercase - letter may be used for additional error code names. *Note Error - Reporting::. - - * Names that begin with either `is' or `to' followed by a lowercase - letter may be used for additional character testing and conversion - functions. *Note Character Handling::. - - * Names that begin with `LC_' followed by an uppercase letter may be - used for additional macros specifying locale attributes. *Note - Locales::. - - * Names of all existing mathematics functions (*note Mathematics::) - suffixed with `f' or `l' are reserved for corresponding functions - that operate on `float' and `long double' arguments, respectively. - - * Names that begin with `SIG' followed by an uppercase letter are - reserved for additional signal names. *Note Standard Signals::. - - * Names that begin with `SIG_' followed by an uppercase letter are - reserved for additional signal actions. *Note Basic Signal - Handling::. - - * Names beginning with `str', `mem', or `wcs' followed by a - lowercase letter are reserved for additional string and array - functions. *Note String and Array Utilities::. - - * Names that end with `_t' are reserved for additional type names. - - In addition, some individual header files reserve names beyond those -that they actually define. You only need to worry about these -restrictions if your program includes that particular header file. - - * The header file `dirent.h' reserves names prefixed with `d_'. - - * The header file `fcntl.h' reserves names prefixed with `l_', `F_', - `O_', and `S_'. - - * The header file `grp.h' reserves names prefixed with `gr_'. - - * The header file `limits.h' reserves names suffixed with `_MAX'. - - * The header file `pwd.h' reserves names prefixed with `pw_'. - - * The header file `signal.h' reserves names prefixed with `sa_' and - `SA_'. - - * The header file `sys/stat.h' reserves names prefixed with `st_' - and `S_'. - - * The header file `sys/times.h' reserves names prefixed with `tms_'. - - * The header file `termios.h' reserves names prefixed with `c_', - `V', `I', `O', and `TC'; and names prefixed with `B' followed by a - digit. - - -File: libc.info, Node: Feature Test Macros, Prev: Reserved Names, Up: Using the Library - -Feature Test Macros -------------------- - - The exact set of features available when you compile a source file -is controlled by which "feature test macros" you define. - - If you compile your programs using `gcc -ansi', you get only the -ISO C library features, unless you explicitly request additional -features by defining one or more of the feature macros. *Note GNU CC -Command Options: (gcc.info)Invoking GCC, for more information about GCC -options. - - You should define these macros by using `#define' preprocessor -directives at the top of your source code files. These directives -_must_ come before any `#include' of a system header file. It is best -to make them the very first thing in the file, preceded only by -comments. You could also use the `-D' option to GCC, but it's better -if you make the source files indicate their own meaning in a -self-contained way. - - This system exists to allow the library to conform to multiple -standards. Although the different standards are often described as -supersets of each other, they are usually incompatible because larger -standards require functions with names that smaller ones reserve to the -user program. This is not mere pedantry -- it has been a problem in -practice. For instance, some non-GNU programs define functions named -`getline' that have nothing to do with this library's `getline'. They -would not be compilable if all features were enabled indiscriminately. - - This should not be used to verify that a program conforms to a -limited standard. It is insufficient for this purpose, as it will not -protect you from including header files outside the standard, or -relying on semantics undefined within the standard. - - - Macro: _POSIX_SOURCE - If you define this macro, then the functionality from the POSIX.1 - standard (IEEE Standard 1003.1) is available, as well as all of the - ISO C facilities. - - The state of `_POSIX_SOURCE' is irrelevant if you define the macro - `_POSIX_C_SOURCE' to a positive integer. - - - Macro: _POSIX_C_SOURCE - Define this macro to a positive integer to control which POSIX - functionality is made available. The greater the value of this - macro, the more functionality is made available. - - If you define this macro to a value greater than or equal to `1', - then the functionality from the 1990 edition of the POSIX.1 - standard (IEEE Standard 1003.1-1990) is made available. - - If you define this macro to a value greater than or equal to `2', - then the functionality from the 1992 edition of the POSIX.2 - standard (IEEE Standard 1003.2-1992) is made available. - - If you define this macro to a value greater than or equal to - `199309L', then the functionality from the 1993 edition of the - POSIX.1b standard (IEEE Standard 1003.1b-1993) is made available. - - Greater values for `_POSIX_C_SOURCE' will enable future extensions. - The POSIX standards process will define these values as necessary, - and the GNU C Library should support them some time after they - become standardized. The 1996 edition of POSIX.1 (ISO/IEC 9945-1: - 1996) states that if you define `_POSIX_C_SOURCE' to a value - greater than or equal to `199506L', then the functionality from - the 1996 edition is made available. - - - Macro: _BSD_SOURCE - If you define this macro, functionality derived from 4.3 BSD Unix - is included as well as the ISO C, POSIX.1, and POSIX.2 material. - - Some of the features derived from 4.3 BSD Unix conflict with the - corresponding features specified by the POSIX.1 standard. If this - macro is defined, the 4.3 BSD definitions take precedence over the - POSIX definitions. - - Due to the nature of some of the conflicts between 4.3 BSD and - POSIX.1, you need to use a special "BSD compatibility library" - when linking programs compiled for BSD compatibility. This is - because some functions must be defined in two different ways, one - of them in the normal C library, and one of them in the - compatibility library. If your program defines `_BSD_SOURCE', you - must give the option `-lbsd-compat' to the compiler or linker when - linking the program, to tell it to find functions in this special - compatibility library before looking for them in the normal C - library. - - - Macro: _SVID_SOURCE - If you define this macro, functionality derived from SVID is - included as well as the ISO C, POSIX.1, POSIX.2, and X/Open - material. - - - Macro: _XOPEN_SOURCE - - Macro: _XOPEN_SOURCE_EXTENDED - If you define this macro, functionality described in the X/Open - Portability Guide is included. This is a superset of the POSIX.1 - and POSIX.2 functionality and in fact `_POSIX_SOURCE' and - `_POSIX_C_SOURCE' are automatically defined. - - As the unification of all Unices, functionality only available in - BSD and SVID is also included. - - If the macro `_XOPEN_SOURCE_EXTENDED' is also defined, even more - functionality is available. The extra functions will make all - functions available which are necessary for the X/Open Unix brand. - - If the macro `_XOPEN_SOURCE' has the value 500 this includes all - functionality described so far plus some new definitions from the - Single Unix Specification, version 2. - - - Macro: _LARGEFILE_SOURCE - If this macro is defined some extra functions are available which - rectify a few shortcomings in all previous standards. - Specifically, the functions `fseeko' and `ftello' are available. - Without these functions the difference between the ISO C interface - (`fseek', `ftell') and the low-level POSIX interface (`lseek') - would lead to problems. - - This macro was introduced as part of the Large File Support - extension (LFS). - - - Macro: _LARGEFILE64_SOURCE - If you define this macro an additional set of functions is made - available which enables 32 bit systems to use files of sizes beyond - the usual limit of 2GB. This interface is not available if the - system does not support files that large. On systems where the - natural file size limit is greater than 2GB (i.e., on 64 bit - systems) the new functions are identical to the replaced functions. - - The new functionality is made available by a new set of types and - functions which replace the existing ones. The names of these new - objects contain `64' to indicate the intention, e.g., `off_t' vs. - `off64_t' and `fseeko' vs. `fseeko64'. - - This macro was introduced as part of the Large File Support - extension (LFS). It is a transition interface for the period when - 64 bit offsets are not generally used (see `_FILE_OFFSET_BITS'). - - - Macro: _FILE_OFFSET_BITS - This macro determines which file system interface shall be used, - one replacing the other. Whereas `_LARGEFILE64_SOURCE' makes the - 64 bit interface available as an additional interface, - `_FILE_OFFSET_BITS' allows the 64 bit interface to replace the old - interface. - - If `_FILE_OFFSET_BITS' is undefined, or if it is defined to the - value `32', nothing changes. The 32 bit interface is used and - types like `off_t' have a size of 32 bits on 32 bit systems. - - If the macro is defined to the value `64', the large file interface - replaces the old interface. I.e., the functions are not made - available under different names (as they are with - `_LARGEFILE64_SOURCE'). Instead the old function names now - reference the new functions, e.g., a call to `fseeko' now indeed - calls `fseeko64'. - - This macro should only be selected if the system provides - mechanisms for handling large files. On 64 bit systems this macro - has no effect since the `*64' functions are identical to the - normal functions. - - This macro was introduced as part of the Large File Support - extension (LFS). - - - Macro: _ISOC99_SOURCE - Until the revised ISO C standard is widely adopted the new features - are not automatically enabled. The GNU libc nevertheless has a - complete implementation of the new standard and to enable the new - features the macro `_ISOC99_SOURCE' should be defined. - - - Macro: _GNU_SOURCE - If you define this macro, everything is included: ISO C89, - ISO C99, POSIX.1, POSIX.2, BSD, SVID, X/Open, LFS, and GNU - extensions. In the cases where POSIX.1 conflicts with BSD, the - POSIX definitions take precedence. - - If you want to get the full effect of `_GNU_SOURCE' but make the - BSD definitions take precedence over the POSIX definitions, use - this sequence of definitions: - - #define _GNU_SOURCE - #define _BSD_SOURCE - #define _SVID_SOURCE - - Note that if you do this, you must link your program with the BSD - compatibility library by passing the `-lbsd-compat' option to the - compiler or linker. *Note:* If you forget to do this, you may get - very strange errors at run time. - - - Macro: _REENTRANT - - Macro: _THREAD_SAFE - If you define one of these macros, reentrant versions of several - functions get declared. Some of the functions are specified in - POSIX.1c but many others are only available on a few other systems - or are unique to GNU libc. The problem is the delay in the - standardization of the thread safe C library interface. - - Unlike on some other systems, no special version of the C library - must be used for linking. There is only one version but while - compiling this it must have been specified to compile as thread - safe. - - We recommend you use `_GNU_SOURCE' in new programs. If you don't -specify the `-ansi' option to GCC and don't define any of these macros -explicitly, the effect is the same as defining `_POSIX_C_SOURCE' to 2 -and `_POSIX_SOURCE', `_SVID_SOURCE', and `_BSD_SOURCE' to 1. - - When you define a feature test macro to request a larger class of -features, it is harmless to define in addition a feature test macro for -a subset of those features. For example, if you define -`_POSIX_C_SOURCE', then defining `_POSIX_SOURCE' as well has no effect. -Likewise, if you define `_GNU_SOURCE', then defining either -`_POSIX_SOURCE' or `_POSIX_C_SOURCE' or `_SVID_SOURCE' as well has no -effect. - - Note, however, that the features of `_BSD_SOURCE' are not a subset of -any of the other feature test macros supported. This is because it -defines BSD features that take precedence over the POSIX features that -are requested by the other macros. For this reason, defining -`_BSD_SOURCE' in addition to the other feature test macros does have an -effect: it causes the BSD features to take priority over the conflicting -POSIX features. - - -File: libc.info, Node: Roadmap to the Manual, Prev: Using the Library, Up: Introduction - -Roadmap to the Manual -===================== - - Here is an overview of the contents of the remaining chapters of -this manual. - - * *Note Error Reporting::, describes how errors detected by the - library are reported. - - * *Note Language Features::, contains information about library - support for standard parts of the C language, including things - like the `sizeof' operator and the symbolic constant `NULL', how - to write functions accepting variable numbers of arguments, and - constants describing the ranges and other properties of the - numerical types.

It also tells you what standard or system each function, -variable, or macro is derived from. - - -File: libc.info, Node: Error Reporting, Next: Memory, Prev: Introduction, Up: Top - -Error Reporting -*************** - - Many functions in the GNU C library detect and report error -conditions, and sometimes your programs need to check for these error -conditions. For example, when you open an input file, you should -verify that the file was actually opened correctly, and print an error -message or take other appropriate action if the call to the library -function failed. - - This chapter describes how the error reporting facility works. Your -program should include the header file `errno.h' to use this facility. - -* Menu: - -* Checking for Errors:: How errors are reported by library functions. -* Error Codes:: Error code macros; all of these expand - into integer constant values. -* Error Messages:: Mapping error codes onto error messages. - - -File: libc.info, Node: Checking for Errors, Next: Error Codes, Up: Error Reporting - -Checking for Errors -=================== - - Most library functions return a special value to indicate that they -have failed. The special value is typically `-1', a null pointer, or a -constant such as `EOF' that is defined for that purpose. But this -return value tells you only that an error has occurred. To find out -what kind of error it was, you need to look at the error code stored in -the variable `errno'. This variable is declared in the header file -`errno.h'. - - - Variable: volatile int errno - The variable `errno' contains the system error number. You can - change the value of `errno'. - - Since `errno' is declared `volatile', it might be changed - asynchronously by a signal handler; see *Note Defining Handlers::. - However, a properly written signal handler saves and restores the - value of `errno', so you generally do not need to worry about this - possibility except when writing signal handlers. - - The initial value of `errno' at program startup is zero. Many - library functions are guaranteed to set it to certain nonzero - values when they encounter certain kinds of errors. These error - conditions are listed for each function. These functions do not - change `errno' when they succeed; thus, the value of `errno' after - a successful call is not necessarily zero, and you should not use - `errno' to determine _whether_ a call failed. The proper way to - do that is documented for each function. _If_ the call failed, - you can examine `errno'. - - Many library functions can set `errno' to a nonzero value as a - result of calling other library functions which might fail. You - should assume that any library function might alter `errno' when - the function returns an error. - - *Portability Note:* ISO C specifies `errno' as a "modifiable - lvalue" rather than as a variable, permitting it to be implemented - as a macro. For example, its expansion might involve a function - call, like `*_errno ()'. In fact, that is what it is on the GNU - system itself. The GNU library, on non-GNU systems, does whatever - is right for the particular system. - - There are a few library functions, like `sqrt' and `atan', that - return a perfectly legitimate value in case of an error, but also - set `errno'. For these functions, if you want to check to see - whether an error occurred, the recommended method is to set `errno' - to zero before calling the function, and then check its value - afterward. - - All the error codes have symbolic names; they are macros defined in -`errno.h'. The names start with `E' and an upper-case letter or digit; -you should consider names of this form to be reserved names. *Note -Reserved Names::. - - The error code values are all positive integers and are all distinct, -with one exception: `EWOULDBLOCK' and `EAGAIN' are the same. Since the -values are distinct, you can use them as labels in a `switch' -statement; just don't use both `EWOULDBLOCK' and `EAGAIN'. Your -program should not make any other assumptions about the specific values -of these symbolic constants. - - The value of `errno' doesn't necessarily have to correspond to any -of these macros, since some library functions might return other error -codes of their own for other situations. The only values that are -guaranteed to be meaningful for a particular library function are the -ones that this manual lists for that function. - - On non-GNU systems, almost any system call can return `EFAULT' if it -is given an invalid pointer as an argument. Since this could only -happen as a result of a bug in your program, and since it will not -happen on the GNU system, we have saved space by not mentioning -`EFAULT' in the descriptions of individual functions. - - In some Unix systems, many system calls can also return `EFAULT' if -given as an argument a pointer into the stack, and the kernel for some -obscure reason fails in its attempt to extend the stack. If this ever -happens, you should probably try using statically or dynamically -allocated memory instead of stack memory on that system. - diff -u -udbrN glibc-2.3.2/manual/libc.info-20 glibc-2.3.2-200304020432/manual/libc.info-20 --- glibc-2.3.2/manual/libc.info-20 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-20 Thu Jan 1 01:00:00 1970 @@ -1,1137 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

You -can specify any character count value as an argument to `fseek' or -`fseeko' and get reliable results for any random access file. However, -some ISO C systems do not represent file positions in this way. - - On some systems where text streams truly differ from binary streams, -it is impossible to represent the file position of a text stream as a -count of characters from the beginning of the file. For example, the -file position on some systems must encode both a record offset within -the file, and a character offset within the record. - - As a consequence, if you want your programs to be portable to these -systems, you must observe certain rules: - - * The value returned from `ftell' on a text stream has no predictable - relationship to the number of characters you have read so far. - The only thing you can rely on is that you can use it subsequently - as the OFFSET argument to `fseek' or `fseeko' to move back to the - same file position. - - * In a call to `fseek' or `fseeko' on a text stream, either the - OFFSET must be zero, or WHENCE must be `SEEK_SET' and and the - OFFSET must be the result of an earlier call to `ftell' on the - same stream. - - * The value of the file position indicator of a text stream is - undefined while there are characters that have been pushed back - with `ungetc' that haven't been read or discarded. *Note - Unreading::. - - But even if you observe these rules, you may still have trouble for -long files, because `ftell' and `fseek' use a `long int' value to -represent the file position. This type may not have room to encode all -the file positions in a large file. Using the `ftello' and `fseeko' -functions might help here since the `off_t' type is expected to be able -to hold all file position values but this still does not help to handle -additional information which must be associated with a file position. - - So if you do want to support systems with peculiar encodings for the -file positions, it is better to use the functions `fgetpos' and -`fsetpos' instead. These functions represent the file position using -the data type `fpos_t', whose internal representation varies from -system to system. - - These symbols are declared in the header file `stdio.h'. - - - Data Type: fpos_t - This is the type of an object that can encode information about the - file position of a stream, for use by the functions `fgetpos' and - `fsetpos'. - - In the GNU system, `fpos_t' is an opaque data structure that - contains internal data to represent file offset and conversion - state information. In other systems, it might have a different - internal representation. - - When compiling with `_FILE_OFFSET_BITS == 64' on a 32 bit machine - this type is in fact equivalent to `fpos64_t' since the LFS - interface transparently replaces the old interface. - - - Data Type: fpos64_t - This is the type of an object that can encode information about the - file position of a stream, for use by the functions `fgetpos64' and - `fsetpos64'. - - In the GNU system, `fpos64_t' is an opaque data structure that - contains internal data to represent file offset and conversion - state information.

If successful, - `fsetpos' clears the end-of-file indicator on the stream, discards - any characters that were "pushed back" by the use of `ungetc', and - returns a value of zero. Otherwise, `fsetpos' returns a nonzero - value and stores an implementation-defined positive value in - `errno'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32 bit system the function is in fact `fsetpos64'.

This is called "buffering". - - If you are writing programs that do interactive input and output -using streams, you need to understand how buffering works when you -design the user interface to your program.

If STREAM is a null pointer, then `fflush' causes - buffered output on _all_ open output streams to be flushed. - - This function returns `EOF' if a write error occurs, or zero - otherwise. - - - Function: int fflush_unlocked (FILE *STREAM) - The `fflush_unlocked' function is equivalent to the `fflush' - function except that it does not implicitly lock the stream. - - The `fflush' function can be used to flush all streams currently -opened. While this is useful in some situations it does often more than -necessary since it might be done in situations when terminal input is -required and the program wants to be sure that all output is visible on -the terminal. But this means that only line buffered streams have to be -flushed. Solaris introduced a function especially for this.

This buffer will be - freed when you close the stream. - - Otherwise, BUF should be a character array that can hold at least - SIZE characters. You should not free the space for this array as - long as the stream remains open and this array remains its buffer. - You should usually either allocate it statically, or `malloc' - (*note Unconstrained Allocation::) the buffer. Using an automatic - array is not a good idea unless you close the file before exiting - the block that declares the array. - - While the array remains a stream buffer, the stream I/O functions - will use the buffer for their internal purposes.

The buffer is - freed when the stream is closed. - - The argument OPENTYPE is the same as in `fopen' (*note Opening - Streams::). If the OPENTYPE specifies append mode, then the - initial file position is set to the first null character in the - buffer. Otherwise the initial file position is at the beginning - of the buffer. - - When a stream open for writing is flushed or closed, a null - character (zero byte) is written at the end of the buffer if it - fits. You should add an extra byte to the SIZE argument to - account for this. Attempts to write more than SIZE bytes to the - buffer result in an error. - - For a stream open for reading, null characters (zero bytes) in the - buffer do not count as "end of file". Read operations indicate - end of file only when the file position advances past SIZE bytes. - So, if you want to read characters from a null-terminated string, - you should supply the length of the string as the SIZE argument. - - Here is an example of using `fmemopen' to create a stream for -reading from a string: - - #include - - static char buffer[] = "foobar"; - - int - main (void) - { - int ch; - FILE *stream; - - stream = fmemopen (buffer, strlen (buffer), "r"); - while ((ch = fgetc (stream)) != EOF) - printf ("Got %c\n", ch); - fclose (stream); - - return 0; - } - - This program produces the following output: - - Got f - Got o - Got o - Got b - Got a - Got r - - - Function: FILE * open_memstream (char **PTR, size_t *SIZELOC) - This function opens a stream for writing to a buffer.

If - you do more output, you must flush the stream again to store new - values before you use them again. - - A null character is written at the end of the buffer. This null - character is _not_ included in the size value stored at SIZELOC. - - You can move the stream's file position with `fseek' or `fseeko' - (*note File Positioning::).

The stream functions in the library never refer -directly to its contents, and they don't even know what the type is; -they record its address with type `void *'. - - To implement a custom stream, you must specify _how_ to fetch or -store the data in the specified place. You do this by defining "hook -functions" to read, write, change "file position", and close the -stream. All four of these functions will be passed the stream's cookie -so they can tell where to fetch or store the data.

This is described below in the description of - environment variables influencing the behavior. - - The SEVERITY parameter can have one of the values in the following - table: - - `MM_NOSEV' - Nothing is printed, this value is the same as `MM_NULLSEV'. - - `MM_HALT' - This value is printed as `HALT'. - - `MM_ERROR' - This value is printed as `ERROR'. - - `MM_WARNING' - This value is printed as `WARNING'. - - `MM_INFO' - This value is printed as `INFO'. - - The numeric value of these five macros are between `0' and `4'. - Using the environment variable `SEV_LEVEL' or using the - `addseverity' function one can add more severity levels with their - corresponding string to print. This is described below (*note - Adding Severity Classes::). - - If no parameter is ignored the output looks like this: - - LABEL: SEVERITY-STRING: TEXT - TO FIX: ACTION TAG - - The colons, new line characters and the `TO FIX' string are - inserted if necessary, i.e., if the corresponding parameter is not - ignored. - - This function is specified in the X/Open Portability Guide. It is - also available on all systems derived from System V. - - The function returns the value `MM_OK' if no error occurred. If - only the printing to standard error failed, it returns `MM_NOMSG'. - If printing to the console fails, it returns `MM_NOCON'. If - nothing is printed `MM_NOTOK' is returned. Among situations where - all outputs fail this last value is also returned if a parameter - value is incorrect. - - There are two environment variables which influence the behavior of -`fmtmsg'. The first is `MSGVERB'. It is used to control the output -actually happening on standard error (_not_ the console output). Each -of the five fields can explicitly be enabled. To do this the user has -to put the `MSGVERB' variable with a format like the following in the -environment before calling the `fmtmsg' function the first time: - - MSGVERB=KEYWORD[:KEYWORD[:...]] - - Valid KEYWORDs are `label', `severity', `text', `action', and `tag'. -If the environment variable is not given or is the empty string, a not -supported keyword is given or the value is somehow else invalid, no -part of the message is masked out. - - The second environment variable which influences the behavior of -`fmtmsg' is `SEV_LEVEL'. This variable and the change in the behavior -of `fmtmsg' is not specified in the X/Open Portability Guide. It is -available in System V systems, though. It can be used to introduce new -severity levels. By default, only the five severity levels described -above are available. Any other numeric value would make `fmtmsg' print -nothing. - - If the user puts `SEV_LEVEL' with a format like - - SEV_LEVEL=[DESCRIPTION[:DESCRIPTION[:...]]] - -in the environment of the process before the first call to `fmtmsg', -where DESCRIPTION has a value of the form - - SEVERITY-KEYWORD,LEVEL,PRINTSTRING - - The SEVERITY-KEYWORD part is not used by `fmtmsg' but it has to be -present. The LEVEL part is a string representation of a number. The -numeric value must be a number greater than 4. This value must be used -in the SEVERITY parameter of `fmtmsg' to select this class. It is not -possible to overwrite any of the predefined classes. The PRINTSTRING -is the string printed when a message of this class is processed by -`fmtmsg' (see above, `fmtsmg' does not print the numeric value but -instead the string representation). - - -File: libc.info, Node: Adding Severity Classes, Next: Example, Prev: Printing Formatted Messages, Up: Formatted Messages - -Adding Severity Classes ------------------------ - - There is another possibility to introduce severity classes besides -using the environment variable `SEV_LEVEL'. This simplifies the task of -introducing new classes in a running program. One could use the -`setenv' or `putenv' function to set the environment variable, but this -is toilsome. - - - Function: int addseverity (int SEVERITY, const char *STRING) - This function allows the introduction of new severity classes - which can be addressed by the SEVERITY parameter of the `fmtmsg' - function. The SEVERITY parameter of `addseverity' must match the - value for the parameter with the same name of `fmtmsg', and STRING - is the string printed in the actual messages instead of the numeric - value. - - If STRING is `NULL' the severity class with the numeric value - according to SEVERITY is removed. - - It is not possible to overwrite or remove one of the default - severity classes. All calls to `addseverity' with SEVERITY set to - one of the values for the default classes will fail. - - The return value is `MM_OK' if the task was successfully performed. - If the return value is `MM_NOTOK' something went wrong. This could - mean that no more memory is available or a class is not available - when it has to be removed. - - This function is not specified in the X/Open Portability Guide - although the `fmtsmg' function is. It is available on System V - systems. - - -File: libc.info, Node: Example, Prev: Adding Severity Classes, Up: Formatted Messages - -How to use `fmtmsg' and `addseverity' -------------------------------------- - - Here is a simple example program to illustrate the use of the both -functions described in this section. - - #include - - int - main (void) - { - addseverity (5, "NOTE2"); - fmtmsg (MM_PRINT, "only1field", MM_INFO, "text2", "action2", "tag2"); - fmtmsg (MM_PRINT, "UX:cat", 5, "invalid syntax", "refer to manual", - "UX:cat:001"); - fmtmsg (MM_PRINT, "label:foo", 6, "text", "action", "tag"); - return 0; - } - - The second call to `fmtmsg' illustrates a use of this function as it -usually occurs on System V systems, which heavily use this function. -It seems worthwhile to give a short explanation here of how this system -works on System V. The value of the LABEL field (`UX:cat') says that -the error occurred in the Unix program `cat'. The explanation of the -error follows and the value for the ACTION parameter is `"refer to -manual"'. One could be more specific here, if necessary. The TAG -field contains, as proposed above, the value of the string given for -the LABEL parameter, and additionally a unique ID (`001' in this case). -For a GNU environment this string could contain a reference to the -corresponding node in the Info page for the program. - -Running this program without specifying the `MSGVERB' and `SEV_LEVEL' -function produces the following output: - - UX:cat: NOTE2: invalid syntax - TO FIX: refer to manual UX:cat:001 - - We see the different fields of the message and how the extra glue -(the colons and the `TO FIX' string) are printed. But only one of the -three calls to `fmtmsg' produced output. The first call does not print -anything because the LABEL parameter is not in the correct form. The -string must contain two fields, separated by a colon (*note Printing -Formatted Messages::). The third `fmtmsg' call produced no output -since the class with the numeric value `6' is not defined. Although a -class with numeric value `5' is also not defined by default, the call -to `addseverity' introduces it and the second call to `fmtmsg' produces -the above output. - - When we change the environment of the program to contain -`SEV_LEVEL=XXX,6,NOTE' when running it we get a different result: - - UX:cat: NOTE2: invalid syntax - TO FIX: refer to manual UX:cat:001 - label:foo: NOTE: text - TO FIX: action tag - - Now the third call to `fmtmsg' produced some output and we see how -the string `NOTE' from the environment variable appears in the message. - - Now we can reduce the output by specifying which fields we are -interested in. If we additionally set the environment variable -`MSGVERB' to the value `severity:label:action' we get the following -output: - - UX:cat: NOTE2 - TO FIX: refer to manual - label:foo: NOTE - TO FIX: action - -I.e., the output produced by the TEXT and the TAG parameters to -`fmtmsg' vanished. Please also note that now there is no colon after -the `NOTE' and `NOTE2' strings in the output. This is not necessary -since there is no more output on this line because the text is missing. - - -File: libc.info, Node: Low-Level I/O, Next: File System Interface, Prev: I/O on Streams, Up: Top - -Low-Level Input/Output -********************** - - This chapter describes functions for performing low-level -input/output operations on file descriptors.

The `open' and `creat' functions are declared -in the header file `fcntl.h', while `close' is declared in `unistd.h'. - - - Function: int open (const char *FILENAME, int FLAGS[, mode_t MODE]) - The `open' function creates and returns a new file descriptor for - the file named by FILENAME. Initially, the file position - indicator for the file is at the beginning of the file. The - argument MODE is used only when a file is created, but it doesn't - hurt to supply the argument in any case. - - The FLAGS argument controls how the file is to be opened. This is - a bit mask; you create the value by the bitwise OR of the - appropriate parameters (using the `|' operator in C). *Note File - Status Flags::, for the parameters available. - - The normal return value from `open' is a non-negative integer file - descriptor. In the case of an error, a value of -1 is returned - instead. In addition to the usual file name errors (*note File - Name Errors::), the following `errno' error conditions are defined - for this function: - - `EACCES' - The file exists but is not readable/writable as requested by - the FLAGS argument, the file does not exist and the directory - is unwritable so it cannot be created. - - `EEXIST' - Both `O_CREAT' and `O_EXCL' are set, and the named file - already exists. - - `EINTR' - The `open' operation was interrupted by a signal. *Note - Interrupted Primitives::. - - `EISDIR' - The FLAGS argument specified write access, and the file is a - directory. - - `EMFILE' - The process has too many files open. The maximum number of - file descriptors is controlled by the `RLIMIT_NOFILE' - resource limit; *note Limits on Resources::. - - `ENFILE' - The entire system, or perhaps the file system which contains - the directory, cannot support any additional open files at - the moment. (This problem cannot happen on the GNU system.) - - `ENOENT' - The named file does not exist, and `O_CREAT' is not specified. - - `ENOSPC' - The directory or file system that would contain the new file - cannot be extended, because there is no disk space left. - - `ENXIO' - `O_NONBLOCK' and `O_WRONLY' are both set in the FLAGS - argument, the file named by FILENAME is a FIFO (*note Pipes - and FIFOs::), and no process has the file open for reading. - - `EROFS' - The file resides on a read-only file system and any of - `O_WRONLY', `O_RDWR', and `O_TRUNC' are set in the FLAGS - argument, or `O_CREAT' is set and the file does not already - exist. - - If on a 32 bit machine the sources are translated with - `_FILE_OFFSET_BITS == 64' the function `open' returns a file - descriptor opened in the large file mode which enables the file - handling functions to use files up to 2^63 bytes in size and - offset from -2^63 to 2^63. This happens transparently for the user - since all of the lowlevel file handling functions are equally - replaced. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `open' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this calls to - `open' should be protected using cancellation handlers. - - The `open' function is the underlying primitive for the `fopen' - and `freopen' functions, that create streams. - - - Function: int open64 (const char *FILENAME, int FLAGS[, mode_t MODE]) - This function is similar to `open'. It returns a file descriptor - which can be used to access the file named by FILENAME. The only - difference is that on 32 bit systems the file is opened in the - large file mode. I.e., file length and file offsets can exceed 31 - bits. - - When the sources are translated with `_FILE_OFFSET_BITS == 64' this - function is actually available under the name `open'. I.e., the - new, extended API using 64 bit file sizes and offsets transparently - replaces the old API. - - - Obsolete function: int creat (const char *FILENAME, mode_t MODE) - This function is obsolete. The call: - - creat (FILENAME, MODE) - - is equivalent to: - - open (FILENAME, O_WRONLY | O_CREAT | O_TRUNC, MODE) - - If on a 32 bit machine the sources are translated with - `_FILE_OFFSET_BITS == 64' the function `creat' returns a file - descriptor opened in the large file mode which enables the file - handling functions to use files up to 2^63 in size and offset from - -2^63 to 2^63. This happens transparently for the user since all - of the lowlevel file handling functions are equally replaced. - - - Obsolete function: int creat64 (const char *FILENAME, mode_t MODE) - This function is similar to `creat'. It returns a file descriptor - which can be used to access the file named by FILENAME. The only - the difference is that on 32 bit systems the file is opened in the - large file mode. I.e., file length and file offsets can exceed 31 - bits. - - To use this file descriptor one must not use the normal operations - but instead the counterparts named `*64', e.g., `read64'. - - When the sources are translated with `_FILE_OFFSET_BITS == 64' this - function is actually available under the name `open'. I.e., the - new, extended API using 64 bit file sizes and offsets transparently - replaces the old API. - - - Function: int close (int FILEDES) - The function `close' closes the file descriptor FILEDES. Closing - a file has the following consequences: - - * The file descriptor is deallocated. - - * Any record locks owned by the process on the file are - unlocked. - - * When all file descriptors associated with a pipe or FIFO have - been closed, any unread data is discarded. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `close' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this, calls to - `close' should be protected using cancellation handlers. - - The normal return value from `close' is 0; a value of -1 is - returned in case of failure. The following `errno' error - conditions are defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `EINTR' - The `close' call was interrupted by a signal. *Note - Interrupted Primitives::. Here is an example of how to - handle `EINTR' properly: - - TEMP_FAILURE_RETRY (close (desc)); - - `ENOSPC' - `EIO' - `EDQUOT' - When the file is accessed by NFS, these errors from `write' - can sometimes not be detected until `close'. *Note I/O - Primitives::, for details on their meaning. - - Please note that there is _no_ separate `close64' function. This - is not necessary since this function does not determine nor depend - on the mode of the file. The kernel which performs the `close' - operation knows which mode the descriptor is used for and can - handle this situation. - - To close a stream, call `fclose' (*note Closing Streams::) instead -of trying to close its underlying file descriptor with `close'. This -flushes any buffered output and updates the stream object to indicate -that it is closed. - - -File: libc.info, Node: I/O Primitives, Next: File Position Primitive, Prev: Opening and Closing Files, Up: Low-Level I/O - -Input and Output Primitives -=========================== - - This section describes the functions for performing primitive input -and output operations on file descriptors: `read', `write', and -`lseek'. These functions are declared in the header file `unistd.h'. - - - Data Type: ssize_t - This data type is used to represent the sizes of blocks that can be - read or written in a single operation. It is similar to `size_t', - but must be a signed type. - - - Function: ssize_t read (int FILEDES, void *BUFFER, size_t SIZE) - The `read' function reads up to SIZE bytes from the file with - descriptor FILEDES, storing the results in the BUFFER. (This is - not necessarily a character string, and no terminating null - character is added.) - - The return value is the number of bytes actually read. This might - be less than SIZE; for example, if there aren't that many bytes - left in the file or if there aren't that many bytes immediately - available. The exact behavior depends on what kind of file it is. - Note that reading less than SIZE bytes is not an error. - - A value of zero indicates end-of-file (except if the value of the - SIZE argument is also zero). This is not considered an error. If - you keep calling `read' while at end-of-file, it will keep - returning zero and doing nothing else. - - If `read' returns at least one character, there is no way you can - tell whether end-of-file was reached. But if you did reach the - end, the next read will return zero. - - In case of an error, `read' returns -1. The following `errno' - error conditions are defined for this function: - - `EAGAIN' - Normally, when no input is immediately available, `read' - waits for some input. But if the `O_NONBLOCK' flag is set - for the file (*note File Status Flags::), `read' returns - immediately without reading any data, and reports this error. - - *Compatibility Note:* Most versions of BSD Unix use a - different error code for this: `EWOULDBLOCK'. In the GNU - library, `EWOULDBLOCK' is an alias for `EAGAIN', so it - doesn't matter which name you use. - - On some systems, reading a large amount of data from a - character special file can also fail with `EAGAIN' if the - kernel cannot find enough physical memory to lock down the - user's pages. This is limited to devices that transfer with - direct memory access into the user's memory, which means it - does not include terminals, since they always use separate - buffers inside the kernel. This problem never happens in the - GNU system. - - Any condition that could result in `EAGAIN' can instead - result in a successful `read' which returns fewer bytes than - requested. Calling `read' again immediately would result in - `EAGAIN'. - - `EBADF' - The FILEDES argument is not a valid file descriptor, or is - not open for reading. - - `EINTR' - `read' was interrupted by a signal while it was waiting for - input. *Note Interrupted Primitives::. A signal will not - necessary cause `read' to return `EINTR'; it may instead - result in a successful `read' which returns fewer bytes than - requested. - - `EIO' - For many devices, and for disk files, this error code - indicates a hardware error. - - `EIO' also occurs when a background process tries to read - from the controlling terminal, and the normal action of - stopping the process by sending it a `SIGTTIN' signal isn't - working. This might happen if the signal is being blocked or - ignored, or because the process group is orphaned. *Note Job - Control::, for more information about job control, and *Note - Signal Handling::, for information about signals. - - Please note that there is no function named `read64'. This is not - necessary since this function does not directly modify or handle - the possibly wide file offset. Since the kernel handles this state - internally, the `read' function can be used for all cases. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `read' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this, calls to - `read' should be protected using cancellation handlers. - - The `read' function is the underlying primitive for all of the - functions that read from streams, such as `fgetc'. - - - Function: ssize_t pread (int FILEDES, void *BUFFER, size_t SIZE, - off_t OFFSET) - The `pread' function is similar to the `read' function. The first - three arguments are identical, and the return values and error - codes also correspond. - - The difference is the fourth argument and its handling. The data - block is not read from the current position of the file descriptor - `filedes'. Instead the data is read from the file starting at - position OFFSET. The position of the file descriptor itself is - not affected by the operation. The value is the same as before - the call. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `pread' function is in fact `pread64' and the type `off_t' has 64 - bits, which makes it possible to handle files up to 2^63 bytes in - length. - - The return value of `pread' describes the number of bytes read. - In the error case it returns -1 like `read' does and the error - codes are also the same, with these additions: - - `EINVAL' - The value given for OFFSET is negative and therefore illegal. - - `ESPIPE' - The file descriptor FILEDES is associate with a pipe or a - FIFO and this device does not allow positioning of the file - pointer. - - The function is an extension defined in the Unix Single - Specification version 2. - - - Function: ssize_t pread64 (int FILEDES, void *BUFFER, size_t SIZE, - off64_t OFFSET) - This function is similar to the `pread' function. The difference - is that the OFFSET parameter is of type `off64_t' instead of - `off_t' which makes it possible on 32 bit machines to address - files larger than 2^31 bytes and up to 2^63 bytes. The file - descriptor `filedes' must be opened using `open64' since otherwise - the large offsets possible with `off64_t' will lead to errors with - a descriptor in small file mode. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' on - a 32 bit machine this function is actually available under the name - `pread' and so transparently replaces the 32 bit interface. - - - Function: ssize_t write (int FILEDES, const void *BUFFER, size_t - SIZE) - The `write' function writes up to SIZE bytes from BUFFER to the - file with descriptor FILEDES. The data in BUFFER is not - necessarily a character string and a null character is output like - any other character. - - The return value is the number of bytes actually written. This - may be SIZE, but can always be smaller. Your program should - always call `write' in a loop, iterating until all the data is - written. - - Once `write' returns, the data is enqueued to be written and can be - read back right away, but it is not necessarily written out to - permanent storage immediately. You can use `fsync' when you need - to be sure your data has been permanently stored before - continuing. (It is more efficient for the system to batch up - consecutive writes and do them all at once when convenient. - Normally they will always be written to disk within a minute or - less.) Modern systems provide another function `fdatasync' which - guarantees integrity only for the file data and is therefore - faster. You can use the `O_FSYNC' open mode to make `write' always - store the data to disk before returning; *note Operating Modes::. - - In the case of an error, `write' returns -1. The following - `errno' error conditions are defined for this function: - - `EAGAIN' - Normally, `write' blocks until the write operation is - complete. But if the `O_NONBLOCK' flag is set for the file - (*note Control Operations::), it returns immediately without - writing any data and reports this error. An example of a - situation that might cause the process to block on output is - writing to a terminal device that supports flow control, - where output has been suspended by receipt of a STOP - character. - - *Compatibility Note:* Most versions of BSD Unix use a - different error code for this: `EWOULDBLOCK'. In the GNU - library, `EWOULDBLOCK' is an alias for `EAGAIN', so it - doesn't matter which name you use. - - On some systems, writing a large amount of data from a - character special file can also fail with `EAGAIN' if the - kernel cannot find enough physical memory to lock down the - user's pages. This is limited to devices that transfer with - direct memory access into the user's memory, which means it - does not include terminals, since they always use separate - buffers inside the kernel. This problem does not arise in the - GNU system. - - `EBADF' - The FILEDES argument is not a valid file descriptor, or is - not open for writing. - - `EFBIG' - The size of the file would become larger than the - implementation can support. - - `EINTR' - The `write' operation was interrupted by a signal while it was - blocked waiting for completion. A signal will not - necessarily cause `write' to return `EINTR'; it may instead - result in a successful `write' which writes fewer bytes than - requested. *Note Interrupted Primitives::. - - `EIO' - For many devices, and for disk files, this error code - indicates a hardware error. - - `ENOSPC' - The device containing the file is full. - - `EPIPE' - This error is returned when you try to write to a pipe or - FIFO that isn't open for reading by any process. When this - happens, a `SIGPIPE' signal is also sent to the process; see - *Note Signal Handling::. - - Unless you have arranged to prevent `EINTR' failures, you should - check `errno' after each failing call to `write', and if the error - was `EINTR', you should simply repeat the call. *Note Interrupted - Primitives::. The easy way to do this is with the macro - `TEMP_FAILURE_RETRY', as follows: - - nbytes = TEMP_FAILURE_RETRY (write (desc, buffer, count)); - - Please note that there is no function named `write64'. This is not - necessary since this function does not directly modify or handle - the possibly wide file offset. Since the kernel handles this state - internally the `write' function can be used for all cases. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `write' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this, calls to - `write' should be protected using cancellation handlers. - - The `write' function is the underlying primitive for all of the - functions that write to streams, such as `fputc'. - - - Function: ssize_t pwrite (int FILEDES, const void *BUFFER, size_t - SIZE, off_t OFFSET) - The `pwrite' function is similar to the `write' function. The - first three arguments are identical, and the return values and - error codes also correspond. - - The difference is the fourth argument and its handling. The data - block is not written to the current position of the file descriptor - `filedes'. Instead the data is written to the file starting at - position OFFSET. The position of the file descriptor itself is - not affected by the operation. The value is the same as before - the call. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `pwrite' function is in fact `pwrite64' and the type `off_t' has - 64 bits, which makes it possible to handle files up to 2^63 bytes - in length. - - The return value of `pwrite' describes the number of written bytes. - In the error case it returns -1 like `write' does and the error - codes are also the same, with these additions: - - `EINVAL' - The value given for OFFSET is negative and therefore illegal. - - `ESPIPE' - The file descriptor FILEDES is associated with a pipe or a - FIFO and this device does not allow positioning of the file - pointer. - - The function is an extension defined in the Unix Single - Specification version 2. - - - Function: ssize_t pwrite64 (int FILEDES, const void *BUFFER, size_t - SIZE, off64_t OFFSET) - This function is similar to the `pwrite' function. The difference - is that the OFFSET parameter is of type `off64_t' instead of - `off_t' which makes it possible on 32 bit machines to address - files larger than 2^31 bytes and up to 2^63 bytes. The file - descriptor `filedes' must be opened using `open64' since otherwise - the large offsets possible with `off64_t' will lead to errors with - a descriptor in small file mode. - - When the source file is compiled using `_FILE_OFFSET_BITS == 64' - on a 32 bit machine this function is actually available under the - name `pwrite' and so transparently replaces the 32 bit interface. - - -File: libc.info, Node: File Position Primitive, Next: Descriptors and Streams, Prev: I/O Primitives, Up: Low-Level I/O - -Setting the File Position of a Descriptor -========================================= - - Just as you can set the file position of a stream with `fseek', you -can set the file position of a descriptor with `lseek'. This specifies -the position in the file for the next `read' or `write' operation. -*Note File Positioning::, for more information on the file position and -what it means. - - To read the current file position value from a descriptor, use -`lseek (DESC, 0, SEEK_CUR)'. - - - Function: off_t lseek (int FILEDES, off_t OFFSET, int WHENCE) - The `lseek' function is used to change the file position of the - file with descriptor FILEDES. - - The WHENCE argument specifies how the OFFSET should be - interpreted, in the same way as for the `fseek' function, and it - must be one of the symbolic constants `SEEK_SET', `SEEK_CUR', or - `SEEK_END'. - - `SEEK_SET' - Specifies that WHENCE is a count of characters from the - beginning of the file. - - `SEEK_CUR' - Specifies that WHENCE is a count of characters from the - current file position. This count may be positive or - negative. - - `SEEK_END' - Specifies that WHENCE is a count of characters from the end of - the file. A negative count specifies a position within the - current extent of the file; a positive count specifies a - position past the current end. If you set the position past - the current end, and actually write data, you will extend the - file with zeros up to that position. - - The return value from `lseek' is normally the resulting file - position, measured in bytes from the beginning of the file. You - can use this feature together with `SEEK_CUR' to read the current - file position. - - If you want to append to the file, setting the file position to the - current end of file with `SEEK_END' is not sufficient. Another - process may write more data after you seek but before you write, - extending the file so the position you write onto clobbers their - data. Instead, use the `O_APPEND' operating mode; *note Operating - Modes::. - - You can set the file position past the current end of the file. - This does not by itself make the file longer; `lseek' never - changes the file. But subsequent output at that position will - extend the file. Characters between the previous end of file and - the new position are filled with zeros. Extending the file in - this way can create a "hole": the blocks of zeros are not actually - allocated on disk, so the file takes up less space than it appears - to; it is then called a "sparse file". - - If the file position cannot be changed, or the operation is in - some way invalid, `lseek' returns a value of -1. The following - `errno' error conditions are defined for this function: - - `EBADF' - The FILEDES is not a valid file descriptor. - - `EINVAL' - The WHENCE argument value is not valid, or the resulting file - offset is not valid. A file offset is invalid. - - `ESPIPE' - The FILEDES corresponds to an object that cannot be - positioned, such as a pipe, FIFO or terminal device. - (POSIX.1 specifies this error only for pipes and FIFOs, but - in the GNU system, you always get `ESPIPE' if the object is - not seekable.) - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `lseek' function is in fact `lseek64' and the type `off_t' has 64 - bits which makes it possible to handle files up to 2^63 bytes in - length. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `lseek' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this calls to - `lseek' should be protected using cancellation handlers. - - The `lseek' function is the underlying primitive for the `fseek', - `fseeko', `ftell', `ftello' and `rewind' functions, which operate - on streams instead of file descriptors. - - - Function: off64_t lseek64 (int FILEDES, off64_t OFFSET, int WHENCE) - This function is similar to the `lseek' function. The difference - is that the OFFSET parameter is of type `off64_t' instead of - `off_t' which makes it possible on 32 bit machines to address - files larger than 2^31 bytes and up to 2^63 bytes. The file - descriptor `filedes' must be opened using `open64' since otherwise - the large offsets possible with `off64_t' will lead to errors with - a descriptor in small file mode. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' on - a 32 bits machine this function is actually available under the - name `lseek' and so transparently replaces the 32 bit interface. - - You can have multiple descriptors for the same file if you open the -file more than once, or if you duplicate a descriptor with `dup'. -Descriptors that come from separate calls to `open' have independent -file positions; using `lseek' on one descriptor has no effect on the -other. For example, - - { - int d1, d2; - char buf[4]; - d1 = open ("foo", O_RDONLY); - d2 = open ("foo", O_RDONLY); - lseek (d1, 1024, SEEK_SET); - read (d2, buf, 4); - } - -will read the first four characters of the file `foo'. (The -error-checking code necessary for a real program has been omitted here -for brevity.) - - By contrast, descriptors made by duplication share a common file -position with the original descriptor that was duplicated. Anything -which alters the file position of one of the duplicates, including -reading or writing data, affects all of them alike. Thus, for example, - - { - int d1, d2, d3; - char buf1[4], buf2[4]; - d1 = open ("foo", O_RDONLY); - d2 = dup (d1); - d3 = dup (d2); - lseek (d3, 1024, SEEK_SET); - read (d1, buf1, 4); - read (d2, buf2, 4); - } - -will read four characters starting with the 1024'th character of `foo', -and then four more characters starting with the 1028'th character. - - - Data Type: off_t - This is an arithmetic data type used to represent file sizes. In - the GNU system, this is equivalent to `fpos_t' or `long int'. - - If the source is compiled with `_FILE_OFFSET_BITS == 64' this type - is transparently replaced by `off64_t'. - - - Data Type: off64_t - This type is used similar to `off_t'. The difference is that even - on 32 bit machines, where the `off_t' type would have 32 bits, - `off64_t' has 64 bits and so is able to address files up to 2^63 - bytes in length. - - When compiling with `_FILE_OFFSET_BITS == 64' this type is - available under the name `off_t'. - - These aliases for the `SEEK_...' constants exist for the sake of -compatibility with older BSD systems.

You can get the underlying file descriptor for -an existing stream with the `fileno' function. These functions are -declared in the header file `stdio.h'. - - - Function: FILE * fdopen (int FILEDES, const char *OPENTYPE) - The `fdopen' function returns a new stream for the file descriptor - FILEDES. - - The OPENTYPE argument is interpreted in the same way as for the - `fopen' function (*note Opening Streams::), except that the `b' - option is not permitted; this is because GNU makes no distinction - between text and binary files. Also, `"w"' and `"w+"' do not - cause truncation of the file; these have an effect only when - opening a file, and in this case the file has already been opened. - You must make sure that the OPENTYPE argument matches the actual - mode of the open file descriptor. - - The return value is the new stream. If the stream cannot be - created (for example, if the modes for the file indicated by the - file descriptor do not permit the access specified by the OPENTYPE - argument), a null pointer is returned instead. - - In some other systems, `fdopen' may fail to detect that the modes - for file descriptor do not permit the access specified by - `opentype'. The GNU C library always checks for this. - - For an example showing the use of the `fdopen' function, see *Note -Creating a Pipe::. - - - Function: int fileno (FILE *STREAM) - This function returns the file descriptor associated with the - stream STREAM. If an error is detected (for example, if the STREAM - is not valid) or if STREAM does not do I/O to a file, `fileno' - returns -1. - - - Function: int fileno_unlocked (FILE *STREAM) - The `fileno_unlocked' function is equivalent to the `fileno' - function except that it does not implicitly lock the stream if the - state is `FSETLOCKING_INTERNAL'. - - This function is a GNU extension. - - There are also symbolic constants defined in `unistd.h' for the file -descriptors belonging to the standard streams `stdin', `stdout', and -`stderr'; see *Note Standard Streams::. - -`STDIN_FILENO' - This macro has value `0', which is the file descriptor for - standard input. - -`STDOUT_FILENO' - This macro has value `1', which is the file descriptor for - standard output. - -`STDERR_FILENO' - This macro has value `2', which is the file descriptor for - standard error output. - - -File: libc.info, Node: Stream/Descriptor Precautions, Next: Scatter-Gather, Prev: Descriptors and Streams, Up: Low-Level I/O - -Dangers of Mixing Streams and Descriptors -========================================= - - You can have multiple file descriptors and streams (let's call both -streams and descriptors "channels" for short) connected to the same -file, but you must take care to avoid confusion between channels. There -are two cases to consider: "linked" channels that share a single file -position value, and "independent" channels that have their own file -positions. - - It's best to use just one channel in your program for actual data -transfer to any given file, except when all the access is for input. -For example, if you open a pipe (something you can only do at the file -descriptor level), either do all I/O with the descriptor, or construct a -stream from the descriptor with `fdopen' and then do all I/O with the -stream. - -* Menu: - -* Linked Channels:: Dealing with channels sharing a file position. -* Independent Channels:: Dealing with separately opened, unlinked channels. -* Cleaning Streams:: Cleaning a stream makes it safe to use - another channel. - - -File: libc.info, Node: Linked Channels, Next: Independent Channels, Up: Stream/Descriptor Precautions - -Linked Channels ---------------- - - Channels that come from a single opening share the same file -position; we call them "linked" channels. Linked channels result when -you make a stream from a descriptor using `fdopen', when you get a -descriptor from a stream with `fileno', when you copy a descriptor with -`dup' or `dup2', and when descriptors are inherited during `fork'. For -files that don't support random access, such as terminals and pipes, -_all_ channels are effectively linked. On random-access files, all -append-type output streams are effectively linked to each other. - - If you have been using a stream for I/O (or have just opened the -stream), and you want to do I/O using another channel (either a stream -or a descriptor) that is linked to it, you must first "clean up" the -stream that you have been using. *Note Cleaning Streams::. - - Terminating a process, or executing a new program in the process, -destroys all the streams in the process. If descriptors linked to these -streams persist in other processes, their file positions become -undefined as a result. To prevent this, you must clean up the streams -before destroying them. - - -File: libc.info, Node: Independent Channels, Next: Cleaning Streams, Prev: Linked Channels, Up: Stream/Descriptor Precautions - -Independent Channels --------------------- - - When you open channels (streams or descriptors) separately on a -seekable file, each channel has its own file position. These are called -"independent channels". - - The system handles each channel independently. Most of the time, -this is quite predictable and natural (especially for input): each -channel can read or write sequentially at its own place in the file. -However, if some of the channels are streams, you must take these -precautions: - - * You should clean an output stream after use, before doing anything - else that might read or write from the same part of the file. - - * You should clean an input stream before reading data that may have - been modified using an independent channel. Otherwise, you might - read obsolete data that had been in the stream's buffer. - - If you do output to one channel at the end of the file, this will -certainly leave the other independent channels positioned somewhere -before the new end. You cannot reliably set their file positions to the -new end of file before writing, because the file can always be extended -by another process between when you set the file position and when you -write the data. Instead, use an append-type descriptor or stream; they -always output at the current end of the file. In order to make the -end-of-file position accurate, you must clean the output channel you -were using, if it is a stream. - - It's impossible for two channels to have separate file pointers for a -file that doesn't support random access. Thus, channels for reading or -writing such files are always linked, never independent. Append-type -channels are also always linked. For these channels, follow the rules -for linked channels; see *Note Linked Channels::. - - -File: libc.info, Node: Cleaning Streams, Prev: Independent Channels, Up: Stream/Descriptor Precautions - -Cleaning Streams ----------------- - - On the GNU system, you can clean up any stream with `fclean': - - - Function: int fclean (FILE *STREAM) - Clean up the stream STREAM so that its buffer is empty. If STREAM - is doing output, force it out. If STREAM is doing input, give the - data in the buffer back to the system, arranging to reread it. - - On other systems, you can use `fflush' to clean a stream in most -cases. - - You can skip the `fclean' or `fflush' if you know the stream is -already clean. A stream is clean whenever its buffer is empty. For -example, an unbuffered stream is always clean. An input stream that is -at end-of-file is clean. A line-buffered stream is clean when the last -character output was a newline. However, a just-opened input stream -might not be clean, as its input buffer might not be empty. - - There is one case in which cleaning a stream is impossible on most -systems. This is when the stream is doing input from a file that is not -random-access. Such streams typically read ahead, and when the file is -not random access, there is no way to give back the excess data already -read. When an input stream reads from a random-access file, `fflush' -does clean the stream, but leaves the file pointer at an unpredictable -place; you must set the file pointer before doing any further I/O. On -the GNU system, using `fclean' avoids both of these problems. - - Closing an output-only stream also does `fflush', so this is a valid -way of cleaning an output stream. On the GNU system, closing an input -stream does `fclean'. - - You need not clean a stream before using its descriptor for control -operations such as setting terminal modes; these operations don't affect -the file position and are not affected by it. You can use any -descriptor for these operations, and all channels are affected -simultaneously. However, text already "output" to a stream but still -buffered by the stream will be subject to the new terminal modes when -subsequently flushed. To make sure "past" output is covered by the -terminal settings that were in effect at the time, flush the output -streams for that terminal before setting the modes. *Note Terminal -Modes::. - - -File: libc.info, Node: Scatter-Gather, Next: Memory-mapped I/O, Prev: Stream/Descriptor Precautions, Up: Low-Level I/O - -Fast Scatter-Gather I/O -======================= - - Some applications may need to read or write data to multiple buffers, -which are separated in memory. Although this can be done easily enough -with multiple calls to `read' and `write', it is inefficient because -there is overhead associated with each kernel call. - - Instead, many platforms provide special high-speed primitives to -perform these "scatter-gather" operations in a single kernel call. The -GNU C library will provide an emulation on any system that lacks these -primitives, so they are not a portability threat. They are defined in -`sys/uio.h'. - - These functions are controlled with arrays of `iovec' structures, -which describe the location and size of each buffer. - - - Data Type: struct iovec - The `iovec' structure describes a buffer. It contains two fields: - - `void *iov_base' - Contains the address of a buffer. - - `size_t iov_len' - Contains the length of the buffer. - - - - Function: ssize_t readv (int FILEDES, const struct iovec *VECTOR, - int COUNT) - The `readv' function reads data from FILEDES and scatters it into - the buffers described in VECTOR, which is taken to be COUNT - structures long. As each buffer is filled, data is sent to the - next. - - Note that `readv' is not guaranteed to fill all the buffers. It - may stop at any point, for the same reasons `read' would. - - The return value is a count of bytes (_not_ buffers) read, 0 - indicating end-of-file, or -1 indicating an error. The possible - errors are the same as in `read'. - - - - Function: ssize_t writev (int FILEDES, const struct iovec *VECTOR, - int COUNT) - The `writev' function gathers data from the buffers described in - VECTOR, which is taken to be COUNT structures long, and writes - them to `filedes'. As each buffer is written, it moves on to the - next. - - Like `readv', `writev' may stop midstream under the same - conditions `write' would. - - The return value is a count of bytes written, or -1 indicating an - error. The possible errors are the same as in `write'. - - - Note that if the buffers are small (under about 1kB), high-level -streams may be easier to use than these functions. However, `readv' and -`writev' are more efficient when the individual buffers themselves (as -opposed to the total output), are large. In that case, a high-level -stream would not be able to cache the data effectively. - diff -u -udbrN glibc-2.3.2/manual/libc.info-22 glibc-2.3.2-200304020432/manual/libc.info-22 --- glibc-2.3.2/manual/libc.info-22 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-22 Thu Jan 1 01:00:00 1970 @@ -1,1103 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

When this is done, the file can -be accessed just like an array in the program. - - This is more efficient than `read' or `write', as only the regions -of the file that a program actually accesses are loaded. Accesses to -not-yet-loaded parts of the mmapped region are handled in the same way -as swapped out pages. - - Since mmapped pages can be stored back to their file when physical -memory is low, it is possible to mmap files orders of magnitude larger -than both the physical memory _and_ swap space. The only limit is -address space. The theoretical limit is 4GB on a 32-bit machine - -however, the actual limit will be smaller since some areas will be -reserved for other purposes. If the LFS interface is used the file size -on 32-bit systems is not limited to 2GB (offsets are signed which -reduces the addressable area of 4GB by half); the full 64-bit are -available. - - Memory mapping only works on entire pages of memory. Thus, addresses -for mapping must be page-aligned, and length values will be rounded up. -To determine the size of a page the machine uses one should use - - size_t page_size = (size_t) sysconf (_SC_PAGESIZE); - -These functions are declared in `sys/mman.h'. - - - Function: void * mmap (void *ADDRESS, size_t LENGTH,int PROTECT, int - FLAGS, int FILEDES, off_t OFFSET) - The `mmap' function creates a new mapping, connected to bytes - (OFFSET) to (OFFSET + LENGTH - 1) in the file open on FILEDES. A - new reference for the file specified by FILEDES is created, which - is not removed by closing the file. - - ADDRESS gives a preferred starting address for the mapping. - `NULL' expresses no preference. Any previous mapping at that - address is automatically removed. The address you give may still be - changed, unless you use the `MAP_FIXED' flag. - - PROTECT contains flags that control what kind of access is - permitted.

Inappropriate access will cause a segfault (*note - Program Error Signals::). - - Note that most hardware designs cannot support write permission - without read permission, and many do not distinguish read and - execute permission. Thus, you may receive wider permissions than - you ask for, and mappings of write-only files may be denied even - if you do not use `PROT_READ'. - - FLAGS contains flags that control the nature of the map. One of - `MAP_SHARED' or `MAP_PRIVATE' must be specified. - - They include: - - `MAP_PRIVATE' - This specifies that writes to the region should never be - written back to the attached file. Instead, a copy is made - for the process, and the region will be swapped normally if - memory runs low. No other process will see the changes. - - Since private mappings effectively revert to ordinary memory - when written to, you must have enough virtual memory for a - copy of the entire mmapped region if you use this mode with - `PROT_WRITE'. - - `MAP_SHARED' - This specifies that writes to the region will be written back - to the file. Changes made will be shared immediately with - other processes mmaping the same file. - - Note that actual writing may take place at any time. You - need to use `msync', described below, if it is important that - other processes using conventional I/O get a consistent view - of the file. - - `MAP_FIXED' - This forces the system to use the exact mapping address - specified in ADDRESS and fail if it can't. - - `MAP_ANONYMOUS' - `MAP_ANON' - This flag tells the system to create an anonymous mapping, - not connected to a file. FILEDES and OFF are ignored, and - the region is initialized with zeros. - - Anonymous maps are used as the basic primitive to extend the - heap on some systems. They are also useful to share data - between multiple tasks without creating a file. - - On some systems using private anonymous mmaps is more - efficient than using `malloc' for large blocks. This is not - an issue with the GNU C library, as the included `malloc' - automatically uses `mmap' where appropriate. - - `mmap' returns the address of the new mapping, or -1 for an error. - - Possible errors include: - - `EINVAL' - Either ADDRESS was unusable, or inconsistent FLAGS were given. - - `EACCES' - FILEDES was not open for the type of access specified in - PROTECT. - - `ENOMEM' - Either there is not enough memory for the operation, or the - process is out of address space. - - `ENODEV' - This file is of a type that doesn't support mapping. - - `ENOEXEC' - The file is on a filesystem that doesn't support mapping. - - - - Function: void * mmap64 (void *ADDRESS, size_t LENGTH,int PROTECT, - int FLAGS, int FILEDES, off64_t OFFSET) - The `mmap64' function is equivalent to the `mmap' function but the - OFFSET parameter is of type `off64_t'. On 32-bit systems this - allows the file associated with the FILEDES descriptor to be - larger than 2GB. FILEDES must be a descriptor returned from a - call to `open64' or `fopen64' and `freopen64' where the descriptor - is retrieved with `fileno'. - - When the sources are translated with `_FILE_OFFSET_BITS == 64' this - function is actually available under the name `mmap'. I.e., the - new, extended API using 64 bit file sizes and offsets transparently - replaces the old API. - - - Function: int munmap (void *ADDR, size_t LENGTH) - `munmap' removes any memory maps from (ADDR) to (ADDR + LENGTH). - LENGTH should be the length of the mapping. - - It is safe to unmap multiple mappings in one command, or include - unmapped space in the range. It is also possible to unmap only - part of an existing mapping. However, only entire pages can be - removed. If LENGTH is not an even number of pages, it will be - rounded up. - - It returns 0 for success and -1 for an error. - - One error is possible: - - `EINVAL' - The memory range given was outside the user mmap range or - wasn't page aligned. - - - - Function: int msync (void *ADDRESS, size_t LENGTH, int FLAGS) - When using shared mappings, the kernel can write the file at any - time before the mapping is removed. To be certain data has - actually been written to the file and will be accessible to - non-memory-mapped I/O, it is necessary to use this function. - - It operates on the region ADDRESS to (ADDRESS + LENGTH). It may - be used on part of a mapping or multiple mappings, however the - region given should not contain any unmapped space. - - FLAGS can contain some options: - - `MS_SYNC' - This flag makes sure the data is actually written _to disk_. - Normally `msync' only makes sure that accesses to a file with - conventional I/O reflect the recent changes. - - `MS_ASYNC' - This tells `msync' to begin the synchronization, but not to - wait for it to complete. - - `msync' returns 0 for success and -1 for error. Errors include: - - `EINVAL' - An invalid region was given, or the FLAGS were invalid. - - `EFAULT' - There is no existing mapping in at least part of the given - region. - - - - Function: void * mremap (void *ADDRESS, size_t LENGTH, size_t - NEW_LENGTH, int FLAG) - This function can be used to change the size of an existing memory - area. ADDRESS and LENGTH must cover a region entirely mapped in - the same `mmap' statement. A new mapping with the same - characteristics will be returned with the length NEW_LENGTH. - - One option is possible, `MREMAP_MAYMOVE'. If it is given in FLAGS, - the system may remove the existing mapping and create a new one of - the desired length in another location. - - The address of the resulting mapping is returned, or -1. Possible - error codes include: - - `EFAULT' - There is no existing mapping in at least part of the original - region, or the region covers two or more distinct mappings. - - `EINVAL' - The address given is misaligned or inappropriate. - - `EAGAIN' - The region has pages locked, and if extended it would exceed - the process's resource limit for locked pages. *Note Limits - on Resources::. - - `ENOMEM' - The region is private writable, and insufficient virtual - memory is available to extend it. Also, this error will - occur if `MREMAP_MAYMOVE' is not given and the extension - would collide with another mapped region. - - - This function is only available on a few systems. Except for -performing optional optimizations one should not rely on this function. - - Not all file descriptors may be mapped. Sockets, pipes, and most -devices only allow sequential access and do not fit into the mapping -abstraction. In addition, some regular files may not be mmapable, and -older kernels may not support mapping at all.

For example, some workstations may have devices -such as a digitizing tablet, function button box, or dial box that are -connected via normal asynchronous serial interfaces; good user interface -style requires responding immediately to input on any device. Another -example is a program that acts as a server to several other processes -via pipes or sockets. - - You cannot normally use `read' for this purpose, because this blocks -the program until input is available on one particular file descriptor; -input on other channels won't wake it up. You could set nonblocking -mode and poll each file descriptor in turn, but this is very -inefficient. - - A better solution is to use the `select' function. This blocks the -program until input or output is ready on a specified set of file -descriptors, or until a timer expires, whichever comes first. This -facility is declared in the header file `sys/types.h'. - - In the case of a server socket (*note Listening::), we say that -"input" is available when there are pending connections that could be -accepted (*note Accepting Connections::). `accept' for server sockets -blocks and interacts with `select' just as `read' does for normal input. - - The file descriptor sets for the `select' function are specified as -`fd_set' objects. Here is the description of the data type and some -macros for manipulating these objects. - - - Data Type: fd_set - The `fd_set' data type represents file descriptor sets for the - `select' function. It is actually a bit array. - - - Macro: int FD_SETSIZE - The value of this macro is the maximum number of file descriptors - that a `fd_set' object can hold information about. On systems - with a fixed maximum number, `FD_SETSIZE' is at least that number. - On some systems, including GNU, there is no absolute limit on the - number of descriptors open, but this macro still has a constant - value which controls the number of bits in an `fd_set'; if you get - a file descriptor with a value as high as `FD_SETSIZE', you cannot - put that descriptor into an `fd_set'. - - - Macro: void FD_ZERO (fd_set *SET) - This macro initializes the file descriptor set SET to be the empty - set. - - - Macro: void FD_SET (int FILEDES, fd_set *SET) - This macro adds FILEDES to the file descriptor set SET. - - - Macro: void FD_CLR (int FILEDES, fd_set *SET) - This macro removes FILEDES from the file descriptor set SET. - - - Macro: int FD_ISSET (int FILEDES, fd_set *SET) - This macro returns a nonzero value (true) if FILEDES is a member - of the file descriptor set SET, and zero (false) otherwise. - - Next, here is the description of the `select' function itself. - - - Function: int select (int NFDS, fd_set *READ-FDS, fd_set *WRITE-FDS, - fd_set *EXCEPT-FDS, struct timeval *TIMEOUT) - The `select' function blocks the calling process until there is - activity on any of the specified sets of file descriptors, or - until the timeout period has expired. - - The file descriptors specified by the READ-FDS argument are - checked to see if they are ready for reading; the WRITE-FDS file - descriptors are checked to see if they are ready for writing; and - the EXCEPT-FDS file descriptors are checked for exceptional - conditions. You can pass a null pointer for any of these - arguments if you are not interested in checking for that kind of - condition. - - A file descriptor is considered ready for reading if it is not at - end of file. A server socket is considered ready for reading if - there is a pending connection which can be accepted with `accept'; - *note Accepting Connections::. A client socket is ready for - writing when its connection is fully established; *note - Connecting::. - - "Exceptional conditions" does not mean errors--errors are reported - immediately when an erroneous system call is executed, and do not - constitute a state of the descriptor. Rather, they include - conditions such as the presence of an urgent message on a socket. - (*Note Sockets::, for information on urgent messages.) - - The `select' function checks only the first NFDS file descriptors. - The usual thing is to pass `FD_SETSIZE' as the value of this - argument. - - The TIMEOUT specifies the maximum time to wait. If you pass a - null pointer for this argument, it means to block indefinitely - until one of the file descriptors is ready. Otherwise, you should - provide the time in `struct timeval' format; see *Note - High-Resolution Calendar::. Specify zero as the time (a `struct - timeval' containing all zeros) if you want to find out which - descriptors are ready without waiting if none are ready. - - The normal return value from `select' is the total number of ready - file descriptors in all of the sets. Each of the argument sets is - overwritten with information about the descriptors that are ready - for the corresponding operation. Thus, to see if a particular - descriptor DESC has input, use `FD_ISSET (DESC, READ-FDS)' after - `select' returns. - - If `select' returns because the timeout period expires, it returns - a value of zero. - - Any signal will cause `select' to return immediately. So if your - program uses signals, you can't rely on `select' to keep waiting - for the full time specified. If you want to be sure of waiting - for a particular amount of time, you must check for `EINTR' and - repeat the `select' with a newly calculated timeout based on the - current time. See the example below. See also *Note Interrupted - Primitives::. - - If an error occurs, `select' returns `-1' and does not modify the - argument file descriptor sets. The following `errno' error - conditions are defined for this function: - - `EBADF' - One of the file descriptor sets specified an invalid file - descriptor. - - `EINTR' - The operation was interrupted by a signal. *Note Interrupted - Primitives::. - - `EINVAL' - The TIMEOUT argument is invalid; one of the components is - negative or too large. - - *Portability Note:* The `select' function is a BSD Unix feature. - - Here is an example showing how you can use `select' to establish a -timeout period for reading from a file descriptor.

For this, `sync' is -overkill. - - - Function: int fsync (int FILDES) - The `fsync' function can be used to make sure all data associated - with the open file FILDES is written to the device associated with - the descriptor.

If the thread gets canceled these resources - stay allocated until the program ends. To avoid this, calls to - `fsync' should be protected using cancellation handlers. - - The return value of the function is zero if no error occurred. - Otherwise it is -1 and the global variable ERRNO is set to the - following values: - `EBADF' - The descriptor FILDES is not valid. - - `EINVAL' - No synchronization is possible since the system does not - implement this. - - Sometimes it is not even necessary to write all data associated with -a file descriptor. E.g., in database files which do not change in size -it is enough to write all the file content data to the device. -Meta-information, like the modification time etc., are not that -important and leaving such information uncommitted does not prevent a -successful recovering of the file in case of a problem. - - - Function: int fdatasync (int FILDES) - When a call to the `fdatasync' function returns, it is ensured - that all of the file data is written to the device. For all - pending I/O operations, the parts guaranteeing data integrity - finished. - - Not all systems implement the `fdatasync' operation.

The -new functions allow a program to initiate one or more I/O operations and -then immediately resume normal work while the I/O operations are -executed in parallel.

The -asynchronous I/O operations are controlled using a data structure named -`struct aiocb' ("AIO control block"). It is defined in `aio.h' as -follows. - - - Data Type: struct aiocb - The POSIX.1b standard mandates that the `struct aiocb' structure - contains at least the members described in the following table. - There might be more elements which are used by the implementation, - but depending upon these elements is not portable and is highly - deprecated. - - `int aio_fildes' - This element specifies the file descriptor to be used for the - operation. It must be a legal descriptor, otherwise the - operation will fail. - - The device on which the file is opened must allow the seek - operation. I.e., it is not possible to use any of the AIO - operations on devices like terminals where an `lseek' call - would lead to an error. - - `off_t aio_offset' - This element specifies the offset in the file at which the - operation (input or output) is performed. Since the - operations are carried out in arbitrary order and more than - one operation for one file descriptor can be started, one - cannot expect a current read/write position of the file - descriptor. - - `volatile void *aio_buf' - This is a pointer to the buffer with the data to be written - or the place where the read data is stored. - - `size_t aio_nbytes' - This element specifies the length of the buffer pointed to by - `aio_buf'. - - `int aio_reqprio' - If the platform has defined `_POSIX_PRIORITIZED_IO' and - `_POSIX_PRIORITY_SCHEDULING', the AIO requests are processed - based on the current scheduling priority. The `aio_reqprio' - element can then be used to lower the priority of the AIO - operation. - - `struct sigevent aio_sigevent' - This element specifies how the calling process is notified - once the operation terminates. If the `sigev_notify' element - is `SIGEV_NONE', no notification is sent. If it is - `SIGEV_SIGNAL', the signal determined by `sigev_signo' is - sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD'. In - this case, a thread is created which starts executing the - function pointed to by `sigev_notify_function'. - - `int aio_lio_opcode' - This element is only used by the `lio_listio' and - `lio_listio64' functions. Since these functions allow an - arbitrary number of operations to start at once, and each - operation can be input or output (or nothing), the - information must be stored in the control block. The - possible values are: - - `LIO_READ' - Start a read operation. Read from the file at position - `aio_offset' and store the next `aio_nbytes' bytes in the - buffer pointed to by `aio_buf'. - - `LIO_WRITE' - Start a write operation. Write `aio_nbytes' bytes - starting at `aio_buf' into the file starting at position - `aio_offset'. - - `LIO_NOP' - Do nothing for this control block.

The - `aio_reqprio' element can then be used to lower the priority - of the AIO operation. - - `struct sigevent aio_sigevent' - This element specifies how the calling process is notified - once the operation terminates. If the `sigev_notify', - element is `SIGEV_NONE' no notification is sent. If it is - `SIGEV_SIGNAL', the signal determined by `sigev_signo' is - sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD' in - which case a thread which starts executing the function - pointed to by `sigev_notify_function'. - - `int aio_lio_opcode' - This element is only used by the `lio_listio' and - `[lio_listio64' functions.

If - the `aio_lio_opcode' member is `LIO_WRITE' a write operation is - enqueued. Otherwise the `aio_lio_opcode' must be `LIO_NOP' in - which case this element of LIST is simply ignored.

Another situation is where the `lio_listio' call was - canceled before all requests are processed (*note Cancel AIO - Operations::) and the remaining requests have to be reissued. - - The other members of each element of the array pointed to by - `list' must have values suitable for the operation as described in - the documentation for `aio_read' and `aio_write' above. - - The MODE argument determines how `lio_listio' behaves after having - enqueued all the requests. If MODE is `LIO_WAIT' it waits until - all requests terminated. Otherwise MODE must be `LIO_NOWAIT' and - in this case the function returns immediately after having - enqueued all the requests. In this case the caller gets a - notification of the termination of all requests according to the - SIG parameter. If SIG is `NULL' no notification is send. - Otherwise a signal is sent or a thread is started, just as - described in the description for `aio_read' or `aio_write'. - - If MODE is `LIO_WAIT', the return value of `lio_listio' is 0 when - all requests completed successfully. Otherwise the function - return -1 and `errno' is set accordingly. To find out which - request or requests failed one has to use the `aio_error' function - on all the elements of the array LIST. - - In case MODE is `LIO_NOWAIT', the function returns 0 if all - requests were enqueued correctly. The current state of the - requests can be found using `aio_error' and `aio_return' as - described above. If `lio_listio' returns -1 in this mode, the - global variable `errno' is set accordingly. If a request did not - yet terminate, a call to `aio_error' returns `EINPROGRESS'. If - the value is different, the request is finished and the error - value (or 0) is returned and the result of the operation can be - retrieved using `aio_return'. - - Possible values for `errno' are: - - `EAGAIN' - The resources necessary to queue all the requests are not - available at the moment. The error status for each element - of LIST must be checked to determine which request failed. - - Another reason could be that the system wide limit of AIO - requests is exceeded. This cannot be the case for the - implementation on GNU systems since no arbitrary limits exist. - - `EINVAL' - The MODE parameter is invalid or NENT is larger than - `AIO_LISTIO_MAX'. - - `EIO' - One or more of the request's I/O operations failed. The - error status of each request should be checked to determine - which one failed. - - `ENOSYS' - The `lio_listio' function is not supported. - - If the MODE parameter is `LIO_NOWAIT' and the caller cancels a - request, the error status for this request returned by `aio_error' - is `ECANCELED'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64', this - function is in fact `lio_listio64' since the LFS interface - transparently replaces the normal implementation. - - - Function: int lio_listio64 (int MODE, struct aiocb *const LIST, int - NENT, struct sigevent *SIG) - This function is similar to the `lio_listio' function.

When the operation is performed truly -asynchronously (as with `aio_read' and `aio_write' and with -`lio_listio' when the mode is `LIO_NOWAIT'), one sometimes needs to -know whether a specific request already terminated and if so, what the -result was. The following two functions allow you to get this kind of -information. - - - Function: int aio_error (const struct aiocb *AIOCBP) - This function determines the error state of the request described - by the `struct aiocb' variable pointed to by AIOCBP.

Once the request has terminated the value - `aio_error' returns is either 0 if the request completed - successfully or it returns the value which would be stored in the - `errno' variable if the request would have been done using `read', - `write', or `fsync'. - - The function can return `ENOSYS' if it is not implemented. It - could also return `EINVAL' if the AIOCBP parameter does not refer - to an asynchronous operation whose return status is not yet known. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is in fact `aio_error64' since the LFS interface - transparently replaces the normal implementation. - - - Function: int aio_error64 (const struct aiocb64 *AIOCBP) - This function is similar to `aio_error' with the only difference - that the argument is a reference to a variable of type `struct - aiocb64'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is available under the name `aio_error' and so - transparently replaces the interface for small files on 32 bit - machines. - - - Function: ssize_t aio_return (const struct aiocb *AIOCBP) - This function can be used to retrieve the return status of the - operation carried out by the request described in the variable - pointed to by AIOCBP. As long as the error status of this request - as returned by `aio_error' is `EINPROGRESS' the return of this - function is undefined. - - Once the request is finished this function can be used exactly - once to retrieve the return value. Following calls might lead to - undefined behavior. The return value itself is the value which - would have been returned by the `read', `write', or `fsync' call. - - The function can return `ENOSYS' if it is not implemented. It - could also return `EINVAL' if the AIOCBP parameter does not refer - to an asynchronous operation whose return status is not yet known. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is in fact `aio_return64' since the LFS interface - transparently replaces the normal implementation. - - - Function: int aio_return64 (const struct aiocb64 *AIOCBP) - This function is similar to `aio_return' with the only difference - that the argument is a reference to a variable of type `struct - aiocb64'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is available under the name `aio_return' and so - transparently replaces the interface for small files on 32 bit - machines. - diff -u -udbrN glibc-2.3.2/manual/libc.info-23 glibc-2.3.2-200304020432/manual/libc.info-23 --- glibc-2.3.2/manual/libc.info-23 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-23 Thu Jan 1 01:00:00 1970 @@ -1,1221 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

This would mean for AIO that one wants -to know whether a certain request or a group of request were processed. -This could be done by waiting for the notification sent by the system -after the operation terminated, but this sometimes would mean wasting -resources (mainly computation time). Instead POSIX.1b defines two -functions which will help with most kinds of consistency. - - The `aio_fsync' and `aio_fsync64' functions are only available if -the symbol `_POSIX_SYNCHRONIZED_IO' is defined in `unistd.h'. - - - Function: int aio_fsync (int OP, struct aiocb *AIOCBP) - Calling this function forces all I/O operations operating queued - at the time of the function call operating on the file descriptor - `aiocbp->aio_fildes' into the synchronized I/O completion state - (*note Synchronizing I/O::). The `aio_fsync' function returns - immediately but the notification through the method described in - `aiocbp->aio_sigevent' will happen only after all requests for this - file descriptor have terminated and the file is synchronized. - This also means that requests for this very same file descriptor - which are queued after the synchronization request are not - affected. - - If OP is `O_DSYNC' the synchronization happens as with a call to - `fdatasync'. Otherwise OP should be `O_SYNC' and the - synchronization happens as with `fsync'. - - As long as the synchronization has not happened, a call to - `aio_error' with the reference to the object pointed to by AIOCBP - returns `EINPROGRESS'. Once the synchronization is done - `aio_error' return 0 if the synchronization was not successful. - Otherwise the value returned is the value to which the `fsync' or - `fdatasync' function would have set the `errno' variable. In this - case nothing can be assumed about the consistency for the data - written to this file descriptor. - - The return value of this function is 0 if the request was - successfully enqueued. Otherwise the return value is -1 and - `errno' is set to one of the following values: - - `EAGAIN' - The request could not be enqueued due to temporary lack of - resources. - - `EBADF' - The file descriptor `aiocbp->aio_fildes' is not valid or not - open for writing. - - `EINVAL' - The implementation does not support I/O synchronization or - the OP parameter is other than `O_DSYNC' and `O_SYNC'. - - `ENOSYS' - This function is not implemented. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is in fact `aio_fsync64' since the LFS interface - transparently replaces the normal implementation. - - - Function: int aio_fsync64 (int OP, struct aiocb64 *AIOCBP) - This function is similar to `aio_fsync' with the only difference - that the argument is a reference to a variable of type `struct - aiocb64'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is available under the name `aio_fsync' and so - transparently replaces the interface for small files on 32 bit - machines. - - Another method of synchronization is to wait until one or more -requests of a specific set terminated. This could be achieved by the -`aio_*' functions to notify the initiating process about the -termination but in some situations this is not the ideal solution. In -a program which constantly updates clients somehow connected to the -server it is not always the best solution to go round robin since some -connections might be slow. On the other hand letting the `aio_*' -function notify the caller might also be not the best solution since -whenever the process works on preparing data for on client it makes no -sense to be interrupted by a notification since the new client will not -be handled before the current client is served. For situations like -this `aio_suspend' should be used. - - - Function: int aio_suspend (const struct aiocb *const LIST[], int - NENT, const struct timespec *TIMEOUT) - When calling this function, the calling thread is suspended until - at least one of the requests pointed to by the NENT elements of the - array LIST has completed. If any of the requests has already - completed at the time `aio_suspend' is called, the function returns - immediately. Whether a request has terminated or not is - determined by comparing the error status of the request with - `EINPROGRESS'. If an element of LIST is `NULL', the entry is - simply ignored. - - If no request has finished, the calling process is suspended. If - TIMEOUT is `NULL', the process is not woken until a request has - finished. If TIMEOUT is not `NULL', the process remains suspended - at least as long as specified in TIMEOUT. In this case, - `aio_suspend' returns with an error. - - The return value of the function is 0 if one or more requests from - the LIST have terminated. Otherwise the function returns -1 and - `errno' is set to one of the following values: - - `EAGAIN' - None of the requests from the LIST completed in the time - specified by TIMEOUT. - - `EINTR' - A signal interrupted the `aio_suspend' function. This signal - might also be sent by the AIO implementation while signalling - the termination of one of the requests. - - `ENOSYS' - The `aio_suspend' function is not implemented. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is in fact `aio_suspend64' since the LFS interface - transparently replaces the normal implementation. - - - Function: int aio_suspend64 (const struct aiocb64 *const LIST[], int - NENT, const struct timespec *TIMEOUT) - This function is similar to `aio_suspend' with the only difference - that the argument is a reference to a variable of type `struct - aiocb64'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is available under the name `aio_suspend' and so - transparently replaces the interface for small files on 32 bit - machines. - - -File: libc.info, Node: Cancel AIO Operations, Next: Configuration of AIO, Prev: Synchronizing AIO Operations, Up: Asynchronous I/O - -Cancellation of AIO Operations ------------------------------- - - When one or more requests are asynchronously processed, it might be -useful in some situations to cancel a selected operation, e.g., if it -becomes obvious that the written data is no longer accurate and would -have to be overwritten soon. As an example, assume an application, -which writes data in files in a situation where new incoming data would -have to be written in a file which will be updated by an enqueued -request. The POSIX AIO implementation provides such a function, but -this function is not capable of forcing the cancellation of the -request. It is up to the implementation to decide whether it is -possible to cancel the operation or not. Therefore using this function -is merely a hint. - - - Function: int aio_cancel (int FILDES, struct aiocb *AIOCBP) - The `aio_cancel' function can be used to cancel one or more - outstanding requests. If the AIOCBP parameter is `NULL', the - function tries to cancel all of the outstanding requests which - would process the file descriptor FILDES (i.e., whose `aio_fildes' - member is FILDES). If AIOCBP is not `NULL', `aio_cancel' attempts - to cancel the specific request pointed to by AIOCBP. - - For requests which were successfully canceled, the normal - notification about the termination of the request should take - place. I.e., depending on the `struct sigevent' object which - controls this, nothing happens, a signal is sent or a thread is - started. If the request cannot be canceled, it terminates the - usual way after performing the operation. - - After a request is successfully canceled, a call to `aio_error' - with a reference to this request as the parameter will return - `ECANCELED' and a call to `aio_return' will return -1. If the - request wasn't canceled and is still running the error status is - still `EINPROGRESS'. - - The return value of the function is `AIO_CANCELED' if there were - requests which haven't terminated and which were successfully - canceled. If there is one or more requests left which couldn't be - canceled, the return value is `AIO_NOTCANCELED'. In this case - `aio_error' must be used to find out which of the, perhaps - multiple, requests (in AIOCBP is `NULL') weren't successfully - canceled. If all requests already terminated at the time - `aio_cancel' is called the return value is `AIO_ALLDONE'. - - If an error occurred during the execution of `aio_cancel' the - function returns -1 and sets `errno' to one of the following - values. - - `EBADF' - The file descriptor FILDES is not valid. - - `ENOSYS' - `aio_cancel' is not implemented. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64', this - function is in fact `aio_cancel64' since the LFS interface - transparently replaces the normal implementation. - - - Function: int aio_cancel64 (int FILDES, struct aiocb64 *AIOCBP) - This function is similar to `aio_cancel' with the only difference - that the argument is a reference to a variable of type `struct - aiocb64'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64', this - function is available under the name `aio_cancel' and so - transparently replaces the interface for small files on 32 bit - machines. - - -File: libc.info, Node: Configuration of AIO, Prev: Cancel AIO Operations, Up: Asynchronous I/O - -How to optimize the AIO implementation --------------------------------------- - - The POSIX standard does not specify how the AIO functions are -implemented. They could be system calls, but it is also possible to -emulate them at userlevel. - - At the point of this writing, the available implementation is a -userlevel implementation which uses threads for handling the enqueued -requests. While this implementation requires making some decisions -about limitations, hard limitations are something which is best avoided -in the GNU C library. Therefore, the GNU C library provides a means -for tuning the AIO implementation according to the individual use. - - - Data Type: struct aioinit - This data type is used to pass the configuration or tunable - parameters to the implementation. The program has to initialize - the members of this struct and pass it to the implementation using - the `aio_init' function. - - `int aio_threads' - This member specifies the maximal number of threads which may - be used at any one time. - - `int aio_num' - This number provides an estimate on the maximal number of - simultaneously enqueued requests. - - `int aio_locks' - Unused. - - `int aio_usedba' - Unused. - - `int aio_debug' - Unused. - - `int aio_numusers' - Unused. - - `int aio_reserved[2]' - Unused. - - - Function: void aio_init (const struct aioinit *INIT) - This function must be called before any other AIO function. - Calling it is completely voluntary, as it is only meant to help - the AIO implementation perform better. - - Before calling the `aio_init', function the members of a variable - of type `struct aioinit' must be initialized. Then a reference to - this variable is passed as the parameter to `aio_init' which itself - may or may not pay attention to the hints. - - The function has no return value and no error cases are defined. - It is a extension which follows a proposal from the SGI - implementation in Irix 6. It is not covered by POSIX.1b or Unix98. - - -File: libc.info, Node: Control Operations, Next: Duplicating Descriptors, Prev: Asynchronous I/O, Up: Low-Level I/O - -Control Operations on Files -=========================== - - This section describes how you can perform various other operations -on file descriptors, such as inquiring about or setting flags describing -the status of the file descriptor, manipulating record locks, and the -like. All of these operations are performed by the function `fcntl'. - - The second argument to the `fcntl' function is a command that -specifies which operation to perform. The function and macros that name -various flags that are used with it are declared in the header file -`fcntl.h'. Many of these flags are also used by the `open' function; -see *Note Opening and Closing Files::. - - - Function: int fcntl (int FILEDES, int COMMAND, ...) - The `fcntl' function performs the operation specified by COMMAND - on the file descriptor FILEDES. Some commands require additional - arguments to be supplied. These additional arguments and the - return value and error conditions are given in the detailed - descriptions of the individual commands. - - Briefly, here is a list of what the various commands are. - - `F_DUPFD' - Duplicate the file descriptor (return another file descriptor - pointing to the same open file). *Note Duplicating - Descriptors::. - - `F_GETFD' - Get flags associated with the file descriptor. *Note - Descriptor Flags::. - - `F_SETFD' - Set flags associated with the file descriptor. *Note - Descriptor Flags::. - - `F_GETFL' - Get flags associated with the open file. *Note File Status - Flags::. - - `F_SETFL' - Set flags associated with the open file. *Note File Status - Flags::. - - `F_GETLK' - Get a file lock. *Note File Locks::. - - `F_SETLK' - Set or clear a file lock. *Note File Locks::. - - `F_SETLKW' - Like `F_SETLK', but wait for completion. *Note File Locks::. - - `F_GETOWN' - Get process or process group ID to receive `SIGIO' signals. - *Note Interrupt Input::. - - `F_SETOWN' - Set process or process group ID to receive `SIGIO' signals. - *Note Interrupt Input::. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `fcntl' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this calls to - `fcntl' should be protected using cancellation handlers. - - -File: libc.info, Node: Duplicating Descriptors, Next: Descriptor Flags, Prev: Control Operations, Up: Low-Level I/O - -Duplicating Descriptors -======================= - - You can "duplicate" a file descriptor, or allocate another file -descriptor that refers to the same open file as the original. Duplicate -descriptors share one file position and one set of file status flags -(*note File Status Flags::), but each has its own set of file descriptor -flags (*note Descriptor Flags::). - - The major use of duplicating a file descriptor is to implement -"redirection" of input or output: that is, to change the file or pipe -that a particular file descriptor corresponds to. - - You can perform this operation using the `fcntl' function with the -`F_DUPFD' command, but there are also convenient functions `dup' and -`dup2' for duplicating descriptors. - - The `fcntl' function and flags are declared in `fcntl.h', while -prototypes for `dup' and `dup2' are in the header file `unistd.h'. - - - Function: int dup (int OLD) - This function copies descriptor OLD to the first available - descriptor number (the first number not currently open). It is - equivalent to `fcntl (OLD, F_DUPFD, 0)'. - - - Function: int dup2 (int OLD, int NEW) - This function copies the descriptor OLD to descriptor number NEW. - - If OLD is an invalid descriptor, then `dup2' does nothing; it does - not close NEW. Otherwise, the new duplicate of OLD replaces any - previous meaning of descriptor NEW, as if NEW were closed first. - - If OLD and NEW are different numbers, and OLD is a valid - descriptor number, then `dup2' is equivalent to: - - close (NEW); - fcntl (OLD, F_DUPFD, NEW) - - However, `dup2' does this atomically; there is no instant in the - middle of calling `dup2' at which NEW is closed and not yet a - duplicate of OLD. - - - Macro: int F_DUPFD - This macro is used as the COMMAND argument to `fcntl', to copy the - file descriptor given as the first argument. - - The form of the call in this case is: - - fcntl (OLD, F_DUPFD, NEXT-FILEDES) - - The NEXT-FILEDES argument is of type `int' and specifies that the - file descriptor returned should be the next available one greater - than or equal to this value. - - The return value from `fcntl' with this command is normally the - value of the new file descriptor. A return value of -1 indicates - an error. The following `errno' error conditions are defined for - this command: - - `EBADF' - The OLD argument is invalid. - - `EINVAL' - The NEXT-FILEDES argument is invalid. - - `EMFILE' - There are no more file descriptors available--your program is - already using the maximum. In BSD and GNU, the maximum is - controlled by a resource limit that can be changed; *note - Limits on Resources::, for more information about the - `RLIMIT_NOFILE' limit. - - `ENFILE' is not a possible error code for `dup2' because `dup2' - does not create a new opening of a file; duplicate descriptors do - not count toward the limit which `ENFILE' indicates. `EMFILE' is - possible because it refers to the limit on distinct descriptor - numbers in use in one process. - - Here is an example showing how to use `dup2' to do redirection. -Typically, redirection of the standard streams (like `stdin') is done -by a shell or shell-like program before calling one of the `exec' -functions (*note Executing a File::) to execute a new program in a -child process. When the new program is executed, it creates and -initializes the standard streams to point to the corresponding file -descriptors, before its `main' function is invoked. - - So, to redirect standard input to a file, the shell could do -something like: - - pid = fork (); - if (pid == 0) - { - char *filename; - char *program; - int file; - ... - file = TEMP_FAILURE_RETRY (open (filename, O_RDONLY)); - dup2 (file, STDIN_FILENO); - TEMP_FAILURE_RETRY (close (file)); - execv (program, NULL); - } - - There is also a more detailed example showing how to implement -redirection in the context of a pipeline of processes in *Note -Launching Jobs::. - - -File: libc.info, Node: Descriptor Flags, Next: File Status Flags, Prev: Duplicating Descriptors, Up: Low-Level I/O - -File Descriptor Flags -===================== - - "File descriptor flags" are miscellaneous attributes of a file -descriptor. These flags are associated with particular file -descriptors, so that if you have created duplicate file descriptors -from a single opening of a file, each descriptor has its own set of -flags. - - Currently there is just one file descriptor flag: `FD_CLOEXEC', -which causes the descriptor to be closed if you use any of the -`exec...' functions (*note Executing a File::). - - The symbols in this section are defined in the header file `fcntl.h'. - - - Macro: int F_GETFD - This macro is used as the COMMAND argument to `fcntl', to specify - that it should return the file descriptor flags associated with - the FILEDES argument. - - The normal return value from `fcntl' with this command is a - nonnegative number which can be interpreted as the bitwise OR of - the individual flags (except that currently there is only one flag - to use). - - In case of an error, `fcntl' returns -1. The following `errno' - error conditions are defined for this command: - - `EBADF' - The FILEDES argument is invalid. - - - Macro: int F_SETFD - This macro is used as the COMMAND argument to `fcntl', to specify - that it should set the file descriptor flags associated with the - FILEDES argument. This requires a third `int' argument to specify - the new flags, so the form of the call is: - - fcntl (FILEDES, F_SETFD, NEW-FLAGS) - - The normal return value from `fcntl' with this command is an - unspecified value other than -1, which indicates an error. The - flags and error conditions are the same as for the `F_GETFD' - command. - - The following macro is defined for use as a file descriptor flag with -the `fcntl' function. The value is an integer constant usable as a bit -mask value. - - - Macro: int FD_CLOEXEC - This flag specifies that the file descriptor should be closed when - an `exec' function is invoked; see *Note Executing a File::. When - a file descriptor is allocated (as with `open' or `dup'), this bit - is initially cleared on the new file descriptor, meaning that - descriptor will survive into the new program after `exec'. - - If you want to modify the file descriptor flags, you should get the -current flags with `F_GETFD' and modify the value. Don't assume that -the flags listed here are the only ones that are implemented; your -program may be run years from now and more flags may exist then. For -example, here is a function to set or clear the flag `FD_CLOEXEC' -without altering any other flags: - - /* Set the `FD_CLOEXEC' flag of DESC if VALUE is nonzero, - or clear the flag if VALUE is 0. - Return 0 on success, or -1 on error with `errno' set. */ - - int - set_cloexec_flag (int desc, int value) - { - int oldflags = fcntl (desc, F_GETFD, 0); - /* If reading the flags failed, return error indication now. */ - if (oldflags < 0) - return oldflags; - /* Set just the flag we want to set. */ - if (value != 0) - oldflags |= FD_CLOEXEC; - else - oldflags &= ~FD_CLOEXEC; - /* Store modified flag word in the descriptor. */ - return fcntl (desc, F_SETFD, oldflags); - } - - -File: libc.info, Node: File Status Flags, Next: File Locks, Prev: Descriptor Flags, Up: Low-Level I/O - -File Status Flags -================= - - "File status flags" are used to specify attributes of the opening of -a file. Unlike the file descriptor flags discussed in *Note Descriptor -Flags::, the file status flags are shared by duplicated file descriptors -resulting from a single opening of the file. The file status flags are -specified with the FLAGS argument to `open'; *note Opening and Closing -Files::. - - File status flags fall into three categories, which are described in -the following sections. - - * *Note Access Modes::, specify what type of access is allowed to the - file: reading, writing, or both.

(In the GNU system, they can also allow none of -these, and allow execution of the file as a program.) The access modes -are chosen when the file is opened, and never change. - - - Macro: int O_RDONLY - Open the file for read access. - - - Macro: int O_WRONLY - Open the file for write access. - - - Macro: int O_RDWR - Open the file for both reading and writing. - - In the GNU system (and not in other systems), `O_RDONLY' and -`O_WRONLY' are independent bits that can be bitwise-ORed together, and -it is valid for either bit to be set or clear. This means that -`O_RDWR' is the same as `O_RDONLY|O_WRONLY'. A file access mode of -zero is permissible; it allows no operations that do input or output to -the file, but does allow other operations such as `fchmod'. On the GNU -system, since "read-only" or "write-only" is a misnomer, `fcntl.h' -defines additional names for the file access modes. These names are -preferred when writing GNU-specific code. But most programs will want -to be portable to other POSIX.1 systems and should use the POSIX.1 -names above instead. - - - Macro: int O_READ - Open the file for reading. Same as `O_RDONLY'; only defined on - GNU. - - - Macro: int O_WRITE - Open the file for writing. Same as `O_WRONLY'; only defined on - GNU. - - - Macro: int O_EXEC - Open the file for executing. Only defined on GNU. - - To determine the file access mode with `fcntl', you must extract the -access mode bits from the retrieved file status flags. In the GNU -system, you can just test the `O_READ' and `O_WRITE' bits in the flags -word. But in other POSIX.1 systems, reading and writing access modes -are not stored as distinct bit flags. The portable way to extract the -file access mode bits is with `O_ACCMODE'. - - - Macro: int O_ACCMODE - This macro stands for a mask that can be bitwise-ANDed with the - file status flag value to produce a value representing the file - access mode. The mode will be `O_RDONLY', `O_WRONLY', or `O_RDWR'. - (In the GNU system it could also be zero, and it never includes the - `O_EXEC' bit.) - - -File: libc.info, Node: Open-time Flags, Next: Operating Modes, Prev: Access Modes, Up: File Status Flags - -Open-time Flags ---------------- - - The open-time flags specify options affecting how `open' will behave. -These options are not preserved once the file is open. The exception to -this is `O_NONBLOCK', which is also an I/O operating mode and so it -_is_ saved. *Note Opening and Closing Files::, for how to call `open'. - - There are two sorts of options specified by open-time flags. - - * "File name translation flags" affect how `open' looks up the file - name to locate the file, and whether the file can be created. - - * "Open-time action flags" specify extra operations that `open' will - perform on the file once it is open. - - Here are the file name translation flags. - - - Macro: int O_CREAT - If set, the file will be created if it doesn't already exist. - - - Macro: int O_EXCL - If both `O_CREAT' and `O_EXCL' are set, then `open' fails if the - specified file already exists. This is guaranteed to never - clobber an existing file. - - - Macro: int O_NONBLOCK - This prevents `open' from blocking for a "long time" to open the - file. This is only meaningful for some kinds of files, usually - devices such as serial ports; when it is not meaningful, it is - harmless and ignored. Often opening a port to a modem blocks - until the modem reports carrier detection; if `O_NONBLOCK' is - specified, `open' will return immediately without a carrier. - - Note that the `O_NONBLOCK' flag is overloaded as both an I/O - operating mode and a file name translation flag. This means that - specifying `O_NONBLOCK' in `open' also sets nonblocking I/O mode; - *note Operating Modes::. To open the file without blocking but do - normal I/O that blocks, you must call `open' with `O_NONBLOCK' set - and then call `fcntl' to turn the bit off. - - - Macro: int O_NOCTTY - If the named file is a terminal device, don't make it the - controlling terminal for the process. *Note Job Control::, for - information about what it means to be the controlling terminal. - - In the GNU system and 4.4 BSD, opening a file never makes it the - controlling terminal and `O_NOCTTY' is zero. However, other - systems may use a nonzero value for `O_NOCTTY' and set the - controlling terminal when you open a file that is a terminal - device; so to be portable, use `O_NOCTTY' when it is important to - avoid this. - - The following three file name translation flags exist only in the -GNU system. - - - Macro: int O_IGNORE_CTTY - Do not recognize the named file as the controlling terminal, even - if it refers to the process's existing controlling terminal - device. Operations on the new file descriptor will never induce - job control signals. *Note Job Control::. - - - Macro: int O_NOLINK - If the named file is a symbolic link, open the link itself instead - of the file it refers to. (`fstat' on the new file descriptor will - return the information returned by `lstat' on the link's name.) - - - Macro: int O_NOTRANS - If the named file is specially translated, do not invoke the - translator. Open the bare file the translator itself sees. - - The open-time action flags tell `open' to do additional operations -which are not really related to opening the file. The reason to do them -as part of `open' instead of in separate calls is that `open' can do -them atomically. - - - Macro: int O_TRUNC - Truncate the file to zero length. This option is only useful for - regular files, not special files such as directories or FIFOs. - POSIX.1 requires that you open the file for writing to use - `O_TRUNC'. In BSD and GNU you must have permission to write the - file to truncate it, but you need not open for write access. - - This is the only open-time action flag specified by POSIX.1. - There is no good reason for truncation to be done by `open', - instead of by calling `ftruncate' afterwards. The `O_TRUNC' flag - existed in Unix before `ftruncate' was invented, and is retained - for backward compatibility. - - The remaining operating modes are BSD extensions. They exist only -on some systems. On other systems, these macros are not defined. - - - Macro: int O_SHLOCK - Acquire a shared lock on the file, as with `flock'. *Note File - Locks::. - - If `O_CREAT' is specified, the locking is done atomically when - creating the file. You are guaranteed that no other process will - get the lock on the new file first. - - - Macro: int O_EXLOCK - Acquire an exclusive lock on the file, as with `flock'. *Note - File Locks::. This is atomic like `O_SHLOCK'. - - -File: libc.info, Node: Operating Modes, Next: Getting File Status Flags, Prev: Open-time Flags, Up: File Status Flags - -I/O Operating Modes -------------------- - - The operating modes affect how input and output operations using a -file descriptor work. These flags are set by `open' and can be fetched -and changed with `fcntl'. - - - Macro: int O_APPEND - The bit that enables append mode for the file. If set, then all - `write' operations write the data at the end of the file, extending - it, regardless of the current file position. This is the only - reliable way to append to a file. In append mode, you are - guaranteed that the data you write will always go to the current - end of the file, regardless of other processes writing to the - file. Conversely, if you simply set the file position to the end - of file and write, then another process can extend the file after - you set the file position but before you write, resulting in your - data appearing someplace before the real end of file. - - - Macro: int O_NONBLOCK - The bit that enables nonblocking mode for the file. If this bit - is set, `read' requests on the file can return immediately with a - failure status if there is no input immediately available, instead - of blocking. Likewise, `write' requests can also return - immediately with a failure status if the output can't be written - immediately. - - Note that the `O_NONBLOCK' flag is overloaded as both an I/O - operating mode and a file name translation flag; *note Open-time - Flags::. - - - Macro: int O_NDELAY - This is an obsolete name for `O_NONBLOCK', provided for - compatibility with BSD. It is not defined by the POSIX.1 standard. - - The remaining operating modes are BSD and GNU extensions. They -exist only on some systems. On other systems, these macros are not -defined. - - - Macro: int O_ASYNC - The bit that enables asynchronous input mode. If set, then `SIGIO' - signals will be generated when input is available. *Note - Interrupt Input::. - - Asynchronous input mode is a BSD feature. - - - Macro: int O_FSYNC - The bit that enables synchronous writing for the file. If set, - each `write' call will make sure the data is reliably stored on - disk before returning. Synchronous writing is a BSD feature. - - - Macro: int O_SYNC - This is another name for `O_FSYNC'. They have the same value. - - - Macro: int O_NOATIME - If this bit is set, `read' will not update the access time of the - file. *Note File Times::. This is used by programs that do - backups, so that backing a file up does not count as reading it. - Only the owner of the file or the superuser may use this bit. - - This is a GNU extension. - - -File: libc.info, Node: Getting File Status Flags, Prev: Operating Modes, Up: File Status Flags - -Getting and Setting File Status Flags -------------------------------------- - - The `fcntl' function can fetch or change file status flags. - - - Macro: int F_GETFL - This macro is used as the COMMAND argument to `fcntl', to read the - file status flags for the open file with descriptor FILEDES. - - The normal return value from `fcntl' with this command is a - nonnegative number which can be interpreted as the bitwise OR of - the individual flags. Since the file access modes are not - single-bit values, you can mask off other bits in the returned - flags with `O_ACCMODE' to compare them. - - In case of an error, `fcntl' returns -1. The following `errno' - error conditions are defined for this command: - - `EBADF' - The FILEDES argument is invalid. - - - Macro: int F_SETFL - This macro is used as the COMMAND argument to `fcntl', to set the - file status flags for the open file corresponding to the FILEDES - argument. This command requires a third `int' argument to specify - the new flags, so the call looks like this: - - fcntl (FILEDES, F_SETFL, NEW-FLAGS) - - You can't change the access mode for the file in this way; that is, - whether the file descriptor was opened for reading or writing. - - The normal return value from `fcntl' with this command is an - unspecified value other than -1, which indicates an error. The - error conditions are the same as for the `F_GETFL' command. - - If you want to modify the file status flags, you should get the -current flags with `F_GETFL' and modify the value. Don't assume that -the flags listed here are the only ones that are implemented; your -program may be run years from now and more flags may exist then. For -example, here is a function to set or clear the flag `O_NONBLOCK' -without altering any other flags: - - /* Set the `O_NONBLOCK' flag of DESC if VALUE is nonzero, - or clear the flag if VALUE is 0. - Return 0 on success, or -1 on error with `errno' set. */ - - int - set_nonblock_flag (int desc, int value) - { - int oldflags = fcntl (desc, F_GETFL, 0); - /* If reading the flags failed, return error indication now. */ - if (oldflags == -1) - return -1; - /* Set just the flag we want to set. */ - if (value != 0) - oldflags |= O_NONBLOCK; - else - oldflags &= ~O_NONBLOCK; - /* Store modified flag word in the descriptor. */ - return fcntl (desc, F_SETFL, oldflags); - } - - -File: libc.info, Node: File Locks, Next: Interrupt Input, Prev: File Status Flags, Up: Low-Level I/O - -File Locks -========== - - The remaining `fcntl' commands are used to support "record locking", -which permits multiple cooperating programs to prevent each other from -simultaneously accessing parts of a file in error-prone ways. - - An "exclusive" or "write" lock gives a process exclusive access for -writing to the specified part of the file. While a write lock is in -place, no other process can lock that part of the file. - - A "shared" or "read" lock prohibits any other process from -requesting a write lock on the specified part of the file. However, -other processes can request read locks. - - The `read' and `write' functions do not actually check to see -whether there are any locks in place. If you want to implement a -locking protocol for a file shared by multiple processes, your -application must do explicit `fcntl' calls to request and clear locks -at the appropriate points. - - Locks are associated with processes. A process can only have one -kind of lock set for each byte of a given file. When any file -descriptor for that file is closed by the process, all of the locks -that process holds on that file are released, even if the locks were -made using other descriptors that remain open. Likewise, locks are -released when a process exits, and are not inherited by child processes -created using `fork' (*note Creating a Process::). - - When making a lock, use a `struct flock' to specify what kind of -lock and where. This data type and the associated macros for the -`fcntl' function are declared in the header file `fcntl.h'. - - - Data Type: struct flock - This structure is used with the `fcntl' function to describe a file - lock. It has these members: - - `short int l_type' - Specifies the type of the lock; one of `F_RDLCK', `F_WRLCK', - or `F_UNLCK'. - - `short int l_whence' - This corresponds to the WHENCE argument to `fseek' or - `lseek', and specifies what the offset is relative to. Its - value can be one of `SEEK_SET', `SEEK_CUR', or `SEEK_END'. - - `off_t l_start' - This specifies the offset of the start of the region to which - the lock applies, and is given in bytes relative to the point - specified by `l_whence' member. - - `off_t l_len' - This specifies the length of the region to be locked. A - value of `0' is treated specially; it means the region - extends to the end of the file. - - `pid_t l_pid' - This field is the process ID (*note Process Creation - Concepts::) of the process holding the lock. It is filled in - by calling `fcntl' with the `F_GETLK' command, but is ignored - when making a lock. - - - Macro: int F_GETLK - This macro is used as the COMMAND argument to `fcntl', to specify - that it should get information about a lock. This command - requires a third argument of type `struct flock *' to be passed to - `fcntl', so that the form of the call is: - - fcntl (FILEDES, F_GETLK, LOCKP) - - If there is a lock already in place that would block the lock - described by the LOCKP argument, information about that lock - overwrites `*LOCKP'. Existing locks are not reported if they are - compatible with making a new lock as specified. Thus, you should - specify a lock type of `F_WRLCK' if you want to find out about both - read and write locks, or `F_RDLCK' if you want to find out about - write locks only. - - There might be more than one lock affecting the region specified - by the LOCKP argument, but `fcntl' only returns information about - one of them. The `l_whence' member of the LOCKP structure is set - to `SEEK_SET' and the `l_start' and `l_len' fields set to identify - the locked region. - - If no lock applies, the only change to the LOCKP structure is to - update the `l_type' to a value of `F_UNLCK'. - - The normal return value from `fcntl' with this command is an - unspecified value other than -1, which is reserved to indicate an - error. The following `errno' error conditions are defined for - this command: - - `EBADF' - The FILEDES argument is invalid. - - `EINVAL' - Either the LOCKP argument doesn't specify valid lock - information, or the file associated with FILEDES doesn't - support locks. - - - Macro: int F_SETLK - This macro is used as the COMMAND argument to `fcntl', to specify - that it should set or clear a lock. This command requires a third - argument of type `struct flock *' to be passed to `fcntl', so that - the form of the call is: - - fcntl (FILEDES, F_SETLK, LOCKP) - - If the process already has a lock on any part of the region, the - old lock on that part is replaced with the new lock. You can - remove a lock by specifying a lock type of `F_UNLCK'. - - If the lock cannot be set, `fcntl' returns immediately with a value - of -1. This function does not block waiting for other processes - to release locks. If `fcntl' succeeds, it return a value other - than -1. - - The following `errno' error conditions are defined for this - function: - - `EAGAIN' - `EACCES' - The lock cannot be set because it is blocked by an existing - lock on the file. Some systems use `EAGAIN' in this case, - and other systems use `EACCES'; your program should treat - them alike, after `F_SETLK'. (The GNU system always uses - `EAGAIN'.) - - `EBADF' - Either: the FILEDES argument is invalid; you requested a read - lock but the FILEDES is not open for read access; or, you - requested a write lock but the FILEDES is not open for write - access. - - `EINVAL' - Either the LOCKP argument doesn't specify valid lock - information, or the file associated with FILEDES doesn't - support locks. - - `ENOLCK' - The system has run out of file lock resources; there are - already too many file locks in place. - - Well-designed file systems never report this error, because - they have no limitation on the number of locks. However, you - must still take account of the possibility of this error, as - it could result from network access to a file system on - another machine. - - - Macro: int F_SETLKW - This macro is used as the COMMAND argument to `fcntl', to specify - that it should set or clear a lock. It is just like the `F_SETLK' - command, but causes the process to block (or wait) until the - request can be specified. - - This command requires a third argument of type `struct flock *', as - for the `F_SETLK' command. - - The `fcntl' return values and errors are the same as for the - `F_SETLK' command, but these additional `errno' error conditions - are defined for this command: - - `EINTR' - The function was interrupted by a signal while it was waiting. - *Note Interrupted Primitives::. - - `EDEADLK' - The specified region is being locked by another process. But - that process is waiting to lock a region which the current - process has locked, so waiting for the lock would result in - deadlock. The system does not guarantee that it will detect - all such conditions, but it lets you know if it notices one. - - The following macros are defined for use as values for the `l_type' -member of the `flock' structure. The values are integer constants. - -`F_RDLCK' - This macro is used to specify a read (or shared) lock. - -`F_WRLCK' - This macro is used to specify a write (or exclusive) lock. - -`F_UNLCK' - This macro is used to specify that the region is unlocked. - - As an example of a situation where file locking is useful, consider a -program that can be run simultaneously by several different users, that -logs status information to a common file. One example of such a program -might be a game that uses a file to keep track of high scores. Another -example might be a program that records usage or accounting information -for billing purposes. - - Having multiple copies of the program simultaneously writing to the -file could cause the contents of the file to become mixed up. But you -can prevent this kind of problem by setting a write lock on the file -before actually writing to the file. - - If the program also needs to read the file and wants to make sure -that the contents of the file are in a consistent state, then it can -also use a read lock. While the read lock is set, no other process can -lock that part of the file for writing. - - Remember that file locks are only a _voluntary_ protocol for -controlling access to a file. There is still potential for access to -the file by programs that don't use the lock protocol. - - -File: libc.info, Node: Interrupt Input, Next: IOCTLs, Prev: File Locks, Up: Low-Level I/O - -Interrupt-Driven Input -====================== - - If you set the `O_ASYNC' status flag on a file descriptor (*note -File Status Flags::), a `SIGIO' signal is sent whenever input or output -becomes possible on that file descriptor. The process or process group -to receive the signal can be selected by using the `F_SETOWN' command -to the `fcntl' function. If the file descriptor is a socket, this also -selects the recipient of `SIGURG' signals that are delivered when -out-of-band data arrives on that socket; see *Note Out-of-Band Data::. -(`SIGURG' is sent in any situation where `select' would report the -socket as having an "exceptional condition". *Note Waiting for I/O::.) - - If the file descriptor corresponds to a terminal device, then `SIGIO' -signals are sent to the foreground process group of the terminal. -*Note Job Control::. - - The symbols in this section are defined in the header file `fcntl.h'. - - - Macro: int F_GETOWN - This macro is used as the COMMAND argument to `fcntl', to specify - that it should get information about the process or process group - to which `SIGIO' signals are sent. (For a terminal, this is - actually the foreground process group ID, which you can get using - `tcgetpgrp'; see *Note Terminal Access Functions::.) - - The return value is interpreted as a process ID; if negative, its - absolute value is the process group ID. - - The following `errno' error condition is defined for this command: - - `EBADF' - The FILEDES argument is invalid. - - - Macro: int F_SETOWN - This macro is used as the COMMAND argument to `fcntl', to specify - that it should set the process or process group to which `SIGIO' - signals are sent. This command requires a third argument of type - `pid_t' to be passed to `fcntl', so that the form of the call is: - - fcntl (FILEDES, F_SETOWN, PID) - - The PID argument should be a process ID. You can also pass a - negative number whose absolute value is a process group ID. - - The return value from `fcntl' with this command is -1 in case of - error and some other value if successful. The following `errno' - error conditions are defined for this command: - - `EBADF' - The FILEDES argument is invalid. - - `ESRCH' - There is no process or process group corresponding to PID. - - -File: libc.info, Node: IOCTLs, Prev: Interrupt Input, Up: Low-Level I/O - -Generic I/O Control operations -============================== - - The GNU system can handle most input/output operations on many -different devices and objects in terms of a few file primitives - -`read', `write' and `lseek'. However, most devices also have a few -peculiar operations which do not fit into this model. Such as: - - * Changing the character font used on a terminal. - - * Telling a magnetic tape system to rewind or fast forward. (Since - they cannot move in byte increments, `lseek' is inapplicable). - - * Ejecting a disk from a drive. - - * Playing an audio track from a CD-ROM drive. - - * Maintaining routing tables for a network. - - - Although some such objects such as sockets and terminals (1) have -special functions of their own, it would not be practical to create -functions for all these cases. - - Instead these minor operations, known as "IOCTL"s, are assigned code -numbers and multiplexed through the `ioctl' function, defined in -`sys/ioctl.h'. The code numbers themselves are defined in many -different headers. - - - Function: int ioctl (int FILEDES, int COMMAND, ...) - The `ioctl' function performs the generic I/O operation COMMAND on - FILEDES. - - A third argument is usually present, either a single number or a - pointer to a structure. The meaning of this argument, the - returned value, and any error codes depends upon the command used. - Often -1 is returned for a failure. - - - On some systems, IOCTLs used by different devices share the same -numbers. Thus, although use of an inappropriate IOCTL _usually_ only -produces an error, you should not attempt to use device-specific IOCTLs -on an unknown device. - - Most IOCTLs are OS-specific and/or only used in special system -utilities, and are thus beyond the scope of this document. For an -example of the use of an IOCTL, see *Note Out-of-Band Data::. - - ---------- Footnotes ---------- - - (1) Actually, the terminal-specific functions are implemented with -IOCTLs on many platforms. - diff -u -udbrN glibc-2.3.2/manual/libc.info-24 glibc-2.3.2-200304020432/manual/libc.info-24 --- glibc-2.3.2/manual/libc.info-24 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-24 Thu Jan 1 01:00:00 1970 @@ -1,1174 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

Unlike the input and output functions (*note I/O on Streams::; -*note Low-Level I/O::), these functions are concerned with operating on -the files themselves rather than on their contents. - - Among the facilities described in this chapter are functions for -examining or modifying directories, functions for renaming and deleting -files, and functions for examining and setting file attributes such as -access permissions and modification times. - -* Menu: - -* Working Directory:: This is used to resolve relative - file names. -* Accessing Directories:: Finding out what files a directory - contains. -* Working with Directory Trees:: Apply actions to all files or a selectable - subset of a directory hierarchy. -* Hard Links:: Adding alternate names to a file. -* Symbolic Links:: A file that ``points to'' a file name. -* Deleting Files:: How to delete a file, and what that means. -* Renaming Files:: Changing a file's name. -* Creating Directories:: A system call just for creating a directory. -* File Attributes:: Attributes of individual files. -* Making Special Files:: How to create special files. -* Temporary Files:: Naming and creating temporary files. - - -File: libc.info, Node: Working Directory, Next: Accessing Directories, Up: File System Interface - -Working Directory -================= - - Each process has associated with it a directory, called its "current -working directory" or simply "working directory", that is used in the -resolution of relative file names (*note File Name Resolution::). - - When you log in and begin a new session, your working directory is -initially set to the home directory associated with your login account -in the system user database. You can find any user's home directory -using the `getpwuid' or `getpwnam' functions; see *Note User Database::. - - Users can change the working directory using shell commands like -`cd'. The functions described in this section are the primitives used -by those commands and by other programs for examining and changing the -working directory. - - Prototypes for these functions are declared in the header file -`unistd.h'. - - - Function: char * getcwd (char *BUFFER, size_t SIZE) - The `getcwd' function returns an absolute file name representing - the current working directory, storing it in the character array - BUFFER that you provide. The SIZE argument is how you tell the - system the allocation size of BUFFER. - - The GNU library version of this function also permits you to - specify a null pointer for the BUFFER argument. Then `getcwd' - allocates a buffer automatically, as with `malloc' (*note - Unconstrained Allocation::). If the SIZE is greater than zero, - then the buffer is that large; otherwise, the buffer is as large - as necessary to hold the result. - - The return value is BUFFER on success and a null pointer on - failure. The following `errno' error conditions are defined for - this function: - - `EINVAL' - The SIZE argument is zero and BUFFER is not a null pointer. - - `ERANGE' - The SIZE argument is less than the length of the working - directory name. You need to allocate a bigger array and try - again. - - `EACCES' - Permission to read or search a component of the file name was - denied. - - You could implement the behavior of GNU's `getcwd (NULL, 0)' using -only the standard behavior of `getcwd': - - char * - gnu_getcwd () - { - size_t size = 100; - - while (1) - { - char *buffer = (char *) xmalloc (size); - if (getcwd (buffer, size) == buffer) - return buffer; - free (buffer); - if (errno != ERANGE) - return 0; - size *= 2; - } - } - -*Note Malloc Examples::, for information about `xmalloc', which is not -a library function but is a customary name used in most GNU software. - - - Deprecated Function: char * getwd (char *BUFFER) - This is similar to `getcwd', but has no way to specify the size of - the buffer. The GNU library provides `getwd' only for backwards - compatibility with BSD. - - The BUFFER argument should be a pointer to an array at least - `PATH_MAX' bytes long (*note Limits for Files::). In the GNU - system there is no limit to the size of a file name, so this is not - necessarily enough space to contain the directory name. That is - why this function is deprecated. - - - Function: char * get_current_dir_name (void) - This `get_current_dir_name' function is bascially equivalent to - `getcwd (NULL, 0)'. The only difference is that the value of the - `PWD' variable is returned if this value is correct. This is a - subtle difference which is visible if the path described by the - `PWD' value is using one or more symbol links in which case the - value returned by `getcwd' can resolve the symbol links and - therefore yield a different result. - - This function is a GNU extension. - - - Function: int chdir (const char *FILENAME) - This function is used to set the process's working directory to - FILENAME. - - The normal, successful return value from `chdir' is `0'. A value - of `-1' is returned to indicate an error. The `errno' error - conditions defined for this function are the usual file name - syntax errors (*note File Name Errors::), plus `ENOTDIR' if the - file FILENAME is not a directory. - - - Function: int fchdir (int FILEDES) - This function is used to set the process's working directory to - directory associated with the file descriptor FILEDES. - - The normal, successful return value from `fchdir' is `0'. A value - of `-1' is returned to indicate an error. The following `errno' - error conditions are defined for this function: - - `EACCES' - Read permission is denied for the directory named by - `dirname'. - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `ENOTDIR' - The file descriptor FILEDES is not associated with a - directory. - - `EINTR' - The function call was interrupt by a signal. - - `EIO' - An I/O error occurred. - - -File: libc.info, Node: Accessing Directories, Next: Working with Directory Trees, Prev: Working Directory, Up: File System Interface - -Accessing Directories -===================== - - The facilities described in this section let you read the contents -of a directory file. This is useful if you want your program to list -all the files in a directory, perhaps as part of a menu. - - The `opendir' function opens a "directory stream" whose elements are -directory entries. You use the `readdir' function on the directory -stream to retrieve these entries, represented as `struct dirent' -objects.

All the symbols are -declared in the header file `dirent.h'. - - - Data Type: struct dirent - This is a structure type used to return information about directory - entries. It contains the following fields: - - `char d_name[]' - This is the null-terminated file name component. This is the - only field you can count on in all POSIX systems. - - `ino_t d_fileno' - This is the file serial number. For BSD compatibility, you - can also refer to this member as `d_ino'. In the GNU system - and most POSIX systems, for most files this the same as the - `st_ino' member that `stat' will return for the file. *Note - File Attributes::. - - `unsigned char d_namlen' - This is the length of the file name, not including the - terminating null character. Its type is `unsigned char' - because that is the integer type of the appropriate size - - `unsigned char d_type' - This is the type of the file, possibly unknown. The - following constants are defined for its value: - - `DT_UNKNOWN' - The type is unknown.

The stream has - type `DIR *'. - - If unsuccessful, `opendir' returns a null pointer. In addition to - the usual file name errors (*note File Name Errors::), the - following `errno' error conditions are defined for this function: - - `EACCES' - Read permission is denied for the directory named by - `dirname'. - - `EMFILE' - The process has too many files open. - - `ENFILE' - The entire system, or perhaps the file system which contains - the directory, cannot support any additional open files at - the moment. (This problem cannot happen on the GNU system.) - - The `DIR' type is typically implemented using a file descriptor, - and the `opendir' function in terms of the `open' function. *Note - Low-Level I/O::. Directory streams and the underlying file - descriptors are closed on `exec' (*note Executing a File::). - - In some situations it can be desirable to get hold of the file -descriptor which is created by the `opendir' call. For instance, to -switch the current working directory to the directory just read the -`fchdir' function could be used. Historically the `DIR' type was -exposed and programs could access the fields.

Instead a separate function is provided to allow -access. - - - Function: int dirfd (DIR *DIRSTREAM) - The function `dirfd' returns the file descriptor associated with - the directory stream DIRSTREAM.

The following `errno' - error conditions are defined for this function: - - `EBADF' - The DIRSTREAM argument is not valid. - - `readdir' is not thread safe. Multiple threads using `readdir' on - the same DIRSTREAM may overwrite the return value. Use - `readdir_r' when this is critical. - - - Function: int readdir_r (DIR *DIRSTREAM, struct dirent *ENTRY, - struct dirent **RESULT) - This function is the reentrant version of `readdir'. Like - `readdir' it returns the next entry from the directory. But to - prevent conflicts between simultaneously running threads the - result is not stored in statically allocated memory. Instead the - argument ENTRY points to a place to store the result. - - Normally `readdir_r' returns zero and sets `*RESULT' to ENTRY. If - there are no more entries in the directory or an error is - detected, `readdir_r' sets `*RESULT' to a null pointer and returns - a nonzero error code, also stored in `errno', as described for - `readdir'. - - *Portability Note:* On some systems `readdir_r' may not return a - NUL terminated string for the file name, even when there is no - `d_reclen' field in `struct dirent' and the file name is the - maximum allowed size. Modern systems all have the `d_reclen' - field, and on old systems multi-threading is not critical. In any - case there is no such problem with the `readdir' function, so that - even on systems without the `d_reclen' member one could use - multiple threads by using external locking. - - It is also important to look at the definition of the `struct - dirent' type. Simply passing a pointer to an object of this type - for the second parameter of `readdir_r' might not be enough. Some - systems don't define the `d_name' element sufficiently long. In - this case the user has to provide additional space. There must be - room for at least `NAME_MAX + 1' characters in the `d_name' array. - Code to call `readdir_r' could look like this: - - union - { - struct dirent d; - char b[offsetof (struct dirent, d_name) + NAME_MAX + 1]; - } u; - - if (readdir_r (dir, &u.d, &res) == 0) - ... - - To support large filesystems on 32-bit machines there are LFS -variants of the last two functions. - - - Function: struct dirent64 * readdir64 (DIR *DIRSTREAM) - The `readdir64' function is just like the `readdir' function - except that it returns a pointer to a record of type `struct - dirent64'.

Sometimes it is -useful to process whole hierarchies of directories and their contained -files. The X/Open specification defines two functions to do this. The -simpler form is derived from an early definition in System V systems -and therefore this function is available on SVID-derived systems. The -prototypes and required definitions can be found in the `ftw.h' header. - - There are four functions in this family: `ftw', `nftw' and their -64-bit counterparts `ftw64' and `nftw64'. These functions take as one -of their arguments a pointer to a callback function of the appropriate -type. - - - Data Type: __ftw_func_t - int (*) (const char *, const struct stat *, int) - - The type of callback functions given to the `ftw' function. The - first parameter points to the file name, the second parameter to an - object of type `struct stat' which is filled in for the file named - in the first parameter. - - The last parameter is a flag giving more information about the - current file. It can have the following values: - - `FTW_F' - The item is either a normal file or a file which does not fit - into one of the following categories. This could be special - files, sockets etc. - - `FTW_D' - The item is a directory. - - `FTW_NS' - The `stat' call failed and so the information pointed to by - the second paramater is invalid. - - `FTW_DNR' - The item is a directory which cannot be read. - - `FTW_SL' - The item is a symbolic link. Since symbolic links are - normally followed seeing this value in a `ftw' callback - function means the referenced file does not exist. The - situation for `nftw' is different. - - This value is only available if the program is compiled with - `_BSD_SOURCE' or `_XOPEN_EXTENDED' defined before including - the first header. The original SVID systems do not have - symbolic links. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' this - type is in fact `__ftw64_func_t' since this mode changes `struct - stat' to be `struct stat64'. - - For the LFS interface and for use in the function `ftw64', the -header `ftw.h' defines another function type. - - - Data Type: __ftw64_func_t - int (*) (const char *, const struct stat64 *, int) - - This type is used just like `__ftw_func_t' for the callback - function, but this time is called from `ftw64'. The second - parameter to the function is a pointer to a variable of type - `struct stat64' which is able to represent the larger values. - - - Data Type: __nftw_func_t - int (*) (const char *, const struct stat *, int, struct FTW *) - - The first three arguments are the same as for the `__ftw_func_t' - type. However for the third argument some additional values are - defined to allow finer differentiation: - `FTW_DP' - The current item is a directory and all subdirectories have - already been visited and reported. This flag is returned - instead of `FTW_D' if the `FTW_DEPTH' flag is passed to - `nftw' (see below). - - `FTW_SLN' - The current item is a stale symbolic link. The file it - points to does not exist. - - The last parameter of the callback function is a pointer to a - structure with some extra information as described below. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' this - type is in fact `__nftw64_func_t' since this mode changes `struct - stat' to be `struct stat64'. - - For the LFS interface there is also a variant of this data type -available which has to be used with the `nftw64' function. - - - Data Type: __nftw64_func_t - int (*) (const char *, const struct stat64 *, int, struct FTW *) - - This type is used just like `__nftw_func_t' for the callback - function, but this time is called from `nftw64'. The second - parameter to the function is this time a pointer to a variable of - type `struct stat64' which is able to represent the larger values. - - - Data Type: struct FTW - The information contained in this structure helps in interpreting - the name parameter and gives some information about the current - state of the traversal of the directory hierarchy. - - `int base' - The value is the offset into the string passed in the first - parameter to the callback function of the beginning of the - file name. The rest of the string is the path of the file. - This information is especially important if the `FTW_CHDIR' - flag was set in calling `nftw' since then the current - directory is the one the current item is found in. - - `int level' - Whilst processing, the code tracks how many directories down - it has gone to find the current file. This nesting level - starts at 0 for files in the initial directory (or is zero - for the initial file if a file was passed). - - - Function: int ftw (const char *FILENAME, __ftw_func_t FUNC, int - DESCRIPTORS) - The `ftw' function calls the callback function given in the - parameter FUNC for every item which is found in the directory - specified by FILENAME and all directories below. The function - follows symbolic links if necessary but does not process an item - twice. If FILENAME is not a directory then it itself is the only - object returned to the callback function. - - The file name passed to the callback function is constructed by - taking the FILENAME parameter and appending the names of all passed - directories and then the local file name. So the callback - function can use this parameter to access the file. `ftw' also - calls `stat' for the file and passes that information on to the - callback function. If this `stat' call was not successful the - failure is indicated by setting the third argument of the callback - function to `FTW_NS'. Otherwise it is set according to the - description given in the account of `__ftw_func_t' above. - - The callback function is expected to return 0 to indicate that no - error occurred and that processing should continue. If an error - occurred in the callback function or it wants `ftw' to return - immediately, the callback function can return a value other than - 0. This is the only correct way to stop the function. The - program must not use `setjmp' or similar techniques to continue - from another place. This would leave resources allocated by the - `ftw' function unfreed. - - The DESCRIPTORS parameter to `ftw' specifies how many file - descriptors it is allowed to consume. The function runs faster - the more descriptors it can use. For each level in the directory - hierarchy at most one descriptor is used, but for very deep ones - any limit on open file descriptors for the process or the system - may be exceeded. Moreover, file descriptor limits in a - multi-threaded program apply to all the threads as a group, and - therefore it is a good idea to supply a reasonable limit to the - number of open descriptors. - - The return value of the `ftw' function is 0 if all callback - function calls returned 0 and all actions performed by the `ftw' - succeeded. If a function call failed (other than calling `stat' - on an item) the function returns -1. If a callback function - returns a value other than 0 this value is returned as the return - value of `ftw'. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `ftw64', i.e. the LFS - interface transparently replaces the old interface. - - - Function: int ftw64 (const char *FILENAME, __ftw64_func_t FUNC, int - DESCRIPTORS) - This function is similar to `ftw' but it can work on filesystems - with large files. File information is reported using a variable - of type `struct stat64' which is passed by reference to the - callback function. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is available under the name `ftw' and - transparently replaces the old implementation. - - - Function: int nftw (const char *FILENAME, __nftw_func_t FUNC, int - DESCRIPTORS, int FLAG) - The `nftw' function works like the `ftw' functions. They call the - callback function FUNC for all items found in the directory - FILENAME and below. At most DESCRIPTORS file descriptors are - consumed during the `nftw' call. - - One difference is that the callback function is of a different - type. It is of type `struct FTW *' and provides the callback - function with the extra information described above. - - A second difference is that `nftw' takes a fourth argument, which - is 0 or a bitwise-OR combination of any of the following values. - - `FTW_PHYS' - While traversing the directory symbolic links are not - followed. Instead symbolic links are reported using the - `FTW_SL' value for the type parameter to the callback - function. If the file referenced by a symbolic link does not - exist `FTW_SLN' is returned instead. - - `FTW_MOUNT' - The callback function is only called for items which are on - the same mounted filesystem as the directory given by the - FILENAME parameter to `nftw'. - - `FTW_CHDIR' - If this flag is given the current working directory is - changed to the directory of the reported object before the - callback function is called. When `ntfw' finally returns the - current directory is restored to its original value. - - `FTW_DEPTH' - If this option is specified then all subdirectories and files - within them are processed before processing the top directory - itself (depth-first processing). This also means the type - flag given to the callback function is `FTW_DP' and not - `FTW_D'. - - The return value is computed in the same way as for `ftw'. `nftw' - returns 0 if no failures occurred and all callback functions - returned 0. In case of internal errors, such as memory problems, - the return value is -1 and ERRNO is set accordingly. If the - return value of a callback invocation was non-zero then that value - is returned. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `nftw64', i.e. the LFS - interface transparently replaces the old interface. - - - Function: int nftw64 (const char *FILENAME, __nftw64_func_t FUNC, - int DESCRIPTORS, int FLAG) - This function is similar to `nftw' but it can work on filesystems - with large files. File information is reported using a variable - of type `struct stat64' which is passed by reference to the - callback function. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is available under the name `nftw' and - transparently replaces the old implementation. - - -File: libc.info, Node: Hard Links, Next: Symbolic Links, Prev: Working with Directory Trees, Up: File System Interface - -Hard Links -========== - - In POSIX systems, one file can have many names at the same time. -All of the names are equally real, and no one of them is preferred to -the others. - - To add a name to a file, use the `link' function. (The new name is -also called a "hard link" to the file.) Creating a new link to a file -does not copy the contents of the file; it simply makes a new name by -which the file can be known, in addition to the file's existing name or -names. - - One file can have names in several directories, so the organization -of the file system is not a strict hierarchy or tree. - - In most implementations, it is not possible to have hard links to the -same file in multiple file systems. `link' reports an error if you try -to make a hard link to the file from another file system when this -cannot be done. - - The prototype for the `link' function is declared in the header file -`unistd.h'. - - - Function: int link (const char *OLDNAME, const char *NEWNAME) - The `link' function makes a new link to the existing file named by - OLDNAME, under the new name NEWNAME. - - This function returns a value of `0' if it is successful and `-1' - on failure. In addition to the usual file name errors (*note File - Name Errors::) for both OLDNAME and NEWNAME, the following `errno' - error conditions are defined for this function: - - `EACCES' - You are not allowed to write to the directory in which the - new link is to be written. - - `EEXIST' - There is already a file named NEWNAME. If you want to replace - this link with a new link, you must remove the old link - explicitly first. - - `EMLINK' - There are already too many links to the file named by OLDNAME. - (The maximum number of links to a file is `LINK_MAX'; see - *Note Limits for Files::.) - - `ENOENT' - The file named by OLDNAME doesn't exist. You can't make a - link to a file that doesn't exist. - - `ENOSPC' - The directory or file system that would contain the new link - is full and cannot be extended. - - `EPERM' - In the GNU system and some others, you cannot make links to - directories. Many systems allow only privileged users to do - so. This error is used to report the problem. - - `EROFS' - The directory containing the new link can't be modified - because it's on a read-only file system. - - `EXDEV' - The directory specified in NEWNAME is on a different file - system than the existing file. - - `EIO' - A hardware error occurred while trying to read or write the - to filesystem. - - -File: libc.info, Node: Symbolic Links, Next: Deleting Files, Prev: Hard Links, Up: File System Interface - -Symbolic Links -============== - - The GNU system supports "soft links" or "symbolic links". This is a -kind of "file" that is essentially a pointer to another file name. -Unlike hard links, symbolic links can be made to directories or across -file systems with no restrictions. You can also make a symbolic link -to a name which is not the name of any file. (Opening this link will -fail until a file by that name is created.) Likewise, if the symbolic -link points to an existing file which is later deleted, the symbolic -link continues to point to the same file name even though the name no -longer names any file. - - The reason symbolic links work the way they do is that special things -happen when you try to open the link. The `open' function realizes you -have specified the name of a link, reads the file name contained in the -link, and opens that file name instead. The `stat' function likewise -operates on the file that the symbolic link points to, instead of on -the link itself. - - By contrast, other operations such as deleting or renaming the file -operate on the link itself. The functions `readlink' and `lstat' also -refrain from following symbolic links, because their purpose is to -obtain information about the link. `link', the function that makes a -hard link, does too. It makes a hard link to the symbolic link, which -one rarely wants. - - Some systems have for some functions operating on files have a limit -on how many symbolic links are followed when resolving a path name. The -limit if it exists is published in the `sys/param.h' header file. - - - Macro: int MAXSYMLINKS - The macro `MAXSYMLINKS' specifies how many symlinks some function - will follow before returning `ELOOP'. Not all functions behave the - same and this value is not the same a that returned for - `_SC_SYMLOOP' by `sysconf'. In fact, the `sysconf' result can - indicate that there is no fixed limit although `MAXSYMLINKS' - exists and has a finite value. - - Prototypes for most of the functions listed in this section are in -`unistd.h'. - - - Function: int symlink (const char *OLDNAME, const char *NEWNAME) - The `symlink' function makes a symbolic link to OLDNAME named - NEWNAME. - - The normal return value from `symlink' is `0'. A return value of - `-1' indicates an error. In addition to the usual file name - syntax errors (*note File Name Errors::), the following `errno' - error conditions are defined for this function: - - `EEXIST' - There is already an existing file named NEWNAME. - - `EROFS' - The file NEWNAME would exist on a read-only file system. - - `ENOSPC' - The directory or file system cannot be extended to make the - new link. - - `EIO' - A hardware error occurred while reading or writing data on - the disk. - - - - Function: int readlink (const char *FILENAME, char *BUFFER, size_t - SIZE) - The `readlink' function gets the value of the symbolic link - FILENAME. The file name that the link points to is copied into - BUFFER. This file name string is _not_ null-terminated; - `readlink' normally returns the number of characters copied. The - SIZE argument specifies the maximum number of characters to copy, - usually the allocation size of BUFFER. - - If the return value equals SIZE, you cannot tell whether or not - there was room to return the entire name. So make a bigger buffer - and call `readlink' again. Here is an example: - - char * - readlink_malloc (const char *filename) - { - int size = 100; - char *buffer = NULL; - - while (1) - { - buffer = (char *) xrealloc (buffer, size); - int nchars = readlink (filename, buffer, size); - if (nchars < 0) - { - free (buffer); - return NULL; - } - if (nchars < size) - return buffer; - size *= 2; - } - } - - A value of `-1' is returned in case of error. In addition to the - usual file name errors (*note File Name Errors::), the following - `errno' error conditions are defined for this function: - - `EINVAL' - The named file is not a symbolic link. - - `EIO' - A hardware error occurred while reading or writing data on - the disk. - - In some situations it is desirable to resolve all the symbolic links -to get the real name of a file where no prefix names a symbolic link -which is followed and no filename in the path is `.' or `..'. This is -for instance desirable if files have to be compare in which case -different names can refer to the same inode. - - - Function: char * canonicalize_file_name (const char *NAME) - The `canonicalize_file_name' function returns the absolute name of - the file named by NAME which contains no `.', `..' components nor - any repeated path separators (`/') or symlinks. The result is - passed back as the return value of the function in a block of - memory allocated with `malloc'. If the result is not used anymore - the memory should be freed with a call to `free'. - - In any of the path components except the last one is missing the - function returns a NULL pointer. This is also what is returned if - the length of the path reaches or exceeds `PATH_MAX' characters. - In any case `errno' is set accordingly. - - `ENAMETOOLONG' - The resulting path is too long. This error only occurs on - systems which have a limit on the file name length. - - `EACCES' - At least one of the path components is not readable. - - `ENOENT' - The input file name is empty. - - `ENOENT' - At least one of the path components does not exist. - - `ELOOP' - More than `MAXSYMLINKS' many symlinks have been followed. - - This function is a GNU extension and is declared in `stdlib.h'. - - The Unix standard includes a similar function which differs from -`canonicalize_file_name' in that the user has to provide the buffer -where the result is placed in. - - - Function: char * realpath (const char *restrict NAME, char *restrict - RESOLVED) - A call to `realpath' where the RESOLVED parameter is `NULL' - behaves exactly like `canonicalize_file_name'. The function - allocates a buffer for the file name and returns a pointer to it. - If RESOLVED is not `NULL' it points to a buffer into which the - result is copied. It is the callers responsibility to allocate a - buffer which is large enough. On systems which define `PATH_MAX' - this means the buffer must be large enough for a pathname of this - size. For systems without limitations on the pathname length the - requirement cannot be met and programs should not call `realpath' - with anything but `NULL' for the second parameter. - - One other difference is that the buffer RESOLVED (if nonzero) will - contain the part of the path component which does not exist or is - not readable if the function returns `NULL' and `errno' is set to - `EACCES' or `ENOENT'. - - This function is declared in `stdlib.h'. - - The advantage of using this function is that it is more widely -available. The drawback is that it reports failures for long path on -systems which have no limits on the file name length. - diff -u -udbrN glibc-2.3.2/manual/libc.info-25 glibc-2.3.2-200304020432/manual/libc.info-25 --- glibc-2.3.2/manual/libc.info-25 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-25 Thu Jan 1 01:00:00 1970 @@ -1,1163 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

However, if - NEWNAME is the name of a directory, `rename' fails in this case. - - If OLDNAME is a directory, then either NEWNAME must not exist or - it must name a directory that is empty. In the latter case, the - existing directory named NEWNAME is deleted first.

They return the attribute information in a -`struct stat' object. All three functions are declared in the header -file `sys/stat.h'. - - - Function: int stat (const char *FILENAME, struct stat *BUF) - The `stat' function returns information about the attributes of the - file named by FILENAME in the structure pointed to by BUF. - - If FILENAME is the name of a symbolic link, the attributes you get - describe the file that the link points to. If the link points to a - nonexistent file name, then `stat' fails reporting a nonexistent - file. - - The return value is `0' if the operation is successful, or `-1' on - failure.

The BUF - pointer points to a variable of type `struct stat64' which is able - to represent the larger values. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is available under the name `fstat' and so transparently - replaces the interface for small files on 32-bit machines. - - - Function: int lstat (const char *FILENAME, struct stat *BUF) - The `lstat' function is like `stat', except that it does not - follow symbolic links. If FILENAME is the name of a symbolic - link, `lstat' returns information about the link itself; otherwise - `lstat' works like `stat'. *Note Symbolic Links::. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' this - function is in fact `lstat64' since the LFS interface transparently - replaces the normal implementation. - - - Function: int lstat64 (const char *FILENAME, struct stat64 *BUF) - This function is similar to `lstat' but it is also able to work on - files larger then 2^31 bytes on 32-bit systems.

This section discusses only the type code, -which you can use to tell whether the file is a directory, socket, -symbolic link, and so on. For details about access permissions see -*Note Permission Bits::. - - There are two ways you can access the file type information in a file -mode. Firstly, for each file type there is a "predicate macro" which -examines a given file mode and returns whether it is of that type or -not. Secondly, you can mask out the rest of the file mode to leave -just the file type code, and compare this against constants for each of -the supported file types. - - All of the symbols listed in this section are defined in the header -file `sys/stat.h'. - - The following predicate macros test the type of a file, given the -value M which is the `st_mode' field returned by `stat' on that file: - - - Macro: int S_ISDIR (mode_t M) - This macro returns non-zero if the file is a directory. - - - Macro: int S_ISCHR (mode_t M) - This macro returns non-zero if the file is a character special - file (a device like a terminal). - - - Macro: int S_ISBLK (mode_t M) - This macro returns non-zero if the file is a block special file (a - device like a disk). - - - Macro: int S_ISREG (mode_t M) - This macro returns non-zero if the file is a regular file. - - - Macro: int S_ISFIFO (mode_t M) - This macro returns non-zero if the file is a FIFO special file, or - a pipe. *Note Pipes and FIFOs::. - - - Macro: int S_ISLNK (mode_t M) - This macro returns non-zero if the file is a symbolic link. *Note - Symbolic Links::. - - - Macro: int S_ISSOCK (mode_t M) - This macro returns non-zero if the file is a socket. *Note - Sockets::. - - An alternate non-POSIX method of testing the file type is supported -for compatibility with BSD. The mode can be bitwise AND-ed with -`S_IFMT' to extract the file type code, and compared to the appropriate -constant. For example, - - S_ISCHR (MODE) - -is equivalent to: - - ((MODE & S_IFMT) == S_IFCHR) - - - Macro: int S_IFMT - This is a bit mask used to extract the file type code from a mode - value. - - These are the symbolic names for the different file type codes: - -`S_IFDIR' - This is the file type constant of a directory file. - -`S_IFCHR' - This is the file type constant of a character-oriented device file. - -`S_IFBLK' - This is the file type constant of a block-oriented device file. - -`S_IFREG' - This is the file type constant of a regular file. - -`S_IFLNK' - This is the file type constant of a symbolic link. - -`S_IFSOCK' - This is the file type constant of a socket. - -`S_IFIFO' - This is the file type constant of a FIFO or pipe. - - The POSIX.1b standard introduced a few more objects which possibly -can be implemented as object in the filesystem. These are message -queues, semaphores, and shared memory objects. To allow -differentiating these objects from other files the POSIX standard -introduces three new test macros. But unlike the other macros it does -not take the value of the `st_mode' field as the parameter.

Each file also has a "group" which is one of -the defined groups. The file owner can often be useful for showing you -who edited the file (especially when you edit with GNU Emacs), but its -main purpose is for access control. - - The file owner and group play a role in determining access because -the file has one set of access permission bits for the owner, another -set that applies to users who belong to the file's group, and a third -set of bits that applies to everyone else. *Note Access Permission::, -for the details of how access is decided based on this data. - - When a file is created, its owner is set to the effective user ID of -the process that creates it (*note Process Persona::). The file's -group ID may be set to either the effective group ID of the process, or -the group ID of the directory that contains the file, depending on the -system where the file is stored. When you access a remote file system, -it behaves according to its own rules, not according to the system your -program is running on. Thus, your program must be prepared to encounter -either kind of behavior no matter what kind of system you run it on. - - You can change the owner and/or group owner of an existing file using -the `chown' function. This is the primitive for the `chown' and -`chgrp' shell commands. - - The prototype for this function is declared in `unistd.h'. - - - Function: int chown (const char *FILENAME, uid_t OWNER, gid_t GROUP) - The `chown' function changes the owner of the file FILENAME to - OWNER, and its group owner to GROUP. - - Changing the owner of the file on certain systems clears the - set-user-ID and set-group-ID permission bits.

On many systems - this bit is 0400. `S_IREAD' is an obsolete synonym provided for - BSD compatibility. - -`S_IWUSR' -`S_IWRITE' - Write permission bit for the owner of the file. Usually 0200. - `S_IWRITE' is an obsolete synonym provided for BSD compatibility. - -`S_IXUSR' -`S_IEXEC' - Execute (for ordinary files) or search (for directories) - permission bit for the owner of the file. Usually 0100. - `S_IEXEC' is an obsolete synonym provided for BSD compatibility. - -`S_IRWXU' - This is equivalent to `(S_IRUSR | S_IWUSR | S_IXUSR)'. - -`S_IRGRP' - Read permission bit for the group owner of the file. Usually 040. - -`S_IWGRP' - Write permission bit for the group owner of the file. Usually 020. - -`S_IXGRP' - Execute or search permission bit for the group owner of the file. - Usually 010. - -`S_IRWXG' - This is equivalent to `(S_IRGRP | S_IWGRP | S_IXGRP)'. - -`S_IROTH' - Read permission bit for other users.

Usually 01. - -`S_IRWXO' - This is equivalent to `(S_IROTH | S_IWOTH | S_IXOTH)'. - -`S_ISUID' - This is the set-user-ID on execute bit, usually 04000. *Note How - Change Persona::. - -`S_ISGID' - This is the set-group-ID on execute bit, usually 02000. *Note How - Change Persona::. - -`S_ISVTX' - This is the "sticky" bit, usually 01000. - - For a directory it gives permission to delete a file in that - directory only if you own that file. Ordinarily, a user can - either delete all the files in a directory or cannot delete any of - them (based on whether the user has write permission for the - directory). The same restriction applies--you must have both - write permission for the directory and own the file you want to - delete. The one exception is that the owner of the directory can - delete any file in the directory, no matter who owns it (provided - the owner has given himself write permission for the directory). - This is commonly used for the `/tmp' directory, where anyone may - create files but not delete files created by other users. - - Originally the sticky bit on an executable file modified the - swapping policies of the system. Normally, when a program - terminated, its pages in core were immediately freed and reused. - If the sticky bit was set on the executable file, the system kept - the pages in core for a while as if the program were still - running. This was advantageous for a program likely to be run - many times in succession. This usage is obsolete in modern - systems. When a program terminates, its pages always remain in - core as long as there is no shortage of memory in the system. - When the program is next run, its pages will still be in core if - no shortage arose since the last run. - - On some modern systems where the sticky bit has no useful meaning - for an executable file, you cannot set the bit at all for a - non-directory. If you try, `chmod' fails with `EFTYPE'; *note - Setting Permissions::. - - Some systems (particularly SunOS) have yet another use for the - sticky bit. If the sticky bit is set on a file that is _not_ - executable, it means the opposite: never cache the pages of this - file at all. The main use of this is for the files on an NFS - server machine which are used as the swap area of diskless client - machines. The idea is that the pages of the file will be cached - in the client's memory, so it is a waste of the server's memory to - cache them a second time. With this usage the sticky bit also - implies that the filesystem may fail to record the file's - modification time onto disk reliably (the idea being that no-one - cares for a swap file). - - This bit is only available on BSD systems (and those derived from - them). Therefore one has to use the `_BSD_SOURCE' feature select - macro to get the definition (*note Feature Test Macros::). - - The actual bit values of the symbols are listed in the table above -so you can decode file mode values when debugging your programs. These -bit values are correct for most systems, but they are not guaranteed. - - *Warning:* Writing explicit numbers for file permissions is bad -practice. Not only is it not portable, it also requires everyone who -reads your program to remember what the bits mean. To make your program -clean use the symbolic names. - - -File: libc.info, Node: Access Permission, Next: Setting Permissions, Prev: Permission Bits, Up: File Attributes - -How Your Access to a File is Decided ------------------------------------- - - Recall that the operating system normally decides access permission -for a file based on the effective user and group IDs of the process and -its supplementary group IDs, together with the file's owner, group and -permission bits. These concepts are discussed in detail in *Note -Process Persona::. - - If the effective user ID of the process matches the owner user ID of -the file, then permissions for read, write, and execute/search are -controlled by the corresponding "user" (or "owner") bits. Likewise, if -any of the effective group ID or supplementary group IDs of the process -matches the group owner ID of the file, then permissions are controlled -by the "group" bits. Otherwise, permissions are controlled by the -"other" bits. - - Privileged users, like `root', can access any file regardless of its -permission bits. As a special case, for a file to be executable even -by a privileged user, at least one of its execute bits must be set. - - -File: libc.info, Node: Setting Permissions, Next: Testing File Access, Prev: Access Permission, Up: File Attributes - -Assigning File Permissions --------------------------- - - The primitive functions for creating files (for example, `open' or -`mkdir') take a MODE argument, which specifies the file permissions to -give the newly created file. This mode is modified by the process's -"file creation mask", or "umask", before it is used. - - The bits that are set in the file creation mask identify permissions -that are always to be disabled for newly created files. For example, if -you set all the "other" access bits in the mask, then newly created -files are not accessible at all to processes in the "other" category, -even if the MODE argument passed to the create function would permit -such access. In other words, the file creation mask is the complement -of the ordinary access permissions you want to grant. - - Programs that create files typically specify a MODE argument that -includes all the permissions that make sense for the particular file. -For an ordinary file, this is typically read and write permission for -all classes of users. These permissions are then restricted as -specified by the individual user's own file creation mask. - - To change the permission of an existing file given its name, call -`chmod'. This function uses the specified permission bits and ignores -the file creation mask. - - In normal use, the file creation mask is initialized by the user's -login shell (using the `umask' shell command), and inherited by all -subprocesses. Application programs normally don't need to worry about -the file creation mask. It will automatically do what it is supposed to -do. - - When your program needs to create a file and bypass the umask for its -access permissions, the easiest way to do this is to use `fchmod' after -opening the file, rather than changing the umask. In fact, changing -the umask is usually done only by shells. They use the `umask' -function. - - The functions in this section are declared in `sys/stat.h'. - - - Function: mode_t umask (mode_t MASK) - The `umask' function sets the file creation mask of the current - process to MASK, and returns the previous value of the file - creation mask. - - Here is an example showing how to read the mask with `umask' - without changing it permanently: - - mode_t - read_umask (void) - { - mode_t mask = umask (0); - umask (mask); - return mask; - } - - However, it is better to use `getumask' if you just want to read - the mask value, because it is reentrant (at least if you use the - GNU operating system). - - - Function: mode_t getumask (void) - Return the current value of the file creation mask for the current - process. This function is a GNU extension. - - - Function: int chmod (const char *FILENAME, mode_t MODE) - The `chmod' function sets the access permission bits for the file - named by FILENAME to MODE. - - If FILENAME is a symbolic link, `chmod' changes the permissions of - the file pointed to by the link, not those of the link itself. - - This function returns `0' if successful and `-1' if not. In - addition to the usual file name errors (*note File Name Errors::), - the following `errno' error conditions are defined for this - function: - - `ENOENT' - The named file doesn't exist. - - `EPERM' - This process does not have permission to change the access - permissions of this file. Only the file's owner (as judged - by the effective user ID of the process) or a privileged user - can change them. - - `EROFS' - The file resides on a read-only file system. - - `EFTYPE' - MODE has the `S_ISVTX' bit (the "sticky bit") set, and the - named file is not a directory. Some systems do not allow - setting the sticky bit on non-directory files, and some do - (and only some of those assign a useful meaning to the bit - for non-directory files). - - You only get `EFTYPE' on systems where the sticky bit has no - useful meaning for non-directory files, so it is always safe - to just clear the bit in MODE and call `chmod' again. *Note - Permission Bits::, for full details on the sticky bit. - - - Function: int fchmod (int FILEDES, int MODE) - This is like `chmod', except that it changes the permissions of the - currently open file given by FILEDES. - - The return value from `fchmod' is `0' on success and `-1' on - failure. The following `errno' error codes are defined for this - function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `EINVAL' - The FILEDES argument corresponds to a pipe or socket, or - something else that doesn't really have access permissions. - - `EPERM' - This process does not have permission to change the access - permissions of this file. Only the file's owner (as judged - by the effective user ID of the process) or a privileged user - can change them. - - `EROFS' - The file resides on a read-only file system. - - -File: libc.info, Node: Testing File Access, Next: File Times, Prev: Setting Permissions, Up: File Attributes - -Testing Permission to Access a File ------------------------------------ - - In some situations it is desirable to allow programs to access files -or devices even if this is not possible with the permissions granted to -the user. One possible solution is to set the setuid-bit of the program -file. If such a program is started the _effective_ user ID of the -process is changed to that of the owner of the program file. So to -allow write access to files like `/etc/passwd', which normally can be -written only by the super-user, the modifying program will have to be -owned by `root' and the setuid-bit must be set. - - But beside the files the program is intended to change the user -should not be allowed to access any file to which s/he would not have -access anyway. The program therefore must explicitly check whether _the -user_ would have the necessary access to a file, before it reads or -writes the file. - - To do this, use the function `access', which checks for access -permission based on the process's _real_ user ID rather than the -effective user ID. (The setuid feature does not alter the real user ID, -so it reflects the user who actually ran the program.) - - There is another way you could check this access, which is easy to -describe, but very hard to use. This is to examine the file mode bits -and mimic the system's own access computation. This method is -undesirable because many systems have additional access control -features; your program cannot portably mimic them, and you would not -want to try to keep track of the diverse features that different systems -have. Using `access' is simple and automatically does whatever is -appropriate for the system you are using. - - `access' is _only_ only appropriate to use in setuid programs. A -non-setuid program will always use the effective ID rather than the -real ID. - - The symbols in this section are declared in `unistd.h'. - - - Function: int access (const char *FILENAME, int HOW) - The `access' function checks to see whether the file named by - FILENAME can be accessed in the way specified by the HOW argument. - The HOW argument either can be the bitwise OR of the flags - `R_OK', `W_OK', `X_OK', or the existence test `F_OK'. - - This function uses the _real_ user and group IDs of the calling - process, rather than the _effective_ IDs, to check for access - permission. As a result, if you use the function from a `setuid' - or `setgid' program (*note How Change Persona::), it gives - information relative to the user who actually ran the program. - - The return value is `0' if the access is permitted, and `-1' - otherwise. (In other words, treated as a predicate function, - `access' returns true if the requested access is _denied_.) - - In addition to the usual file name errors (*note File Name - Errors::), the following `errno' error conditions are defined for - this function: - - `EACCES' - The access specified by HOW is denied. - - `ENOENT' - The file doesn't exist. - - `EROFS' - Write permission was requested for a file on a read-only file - system. - - These macros are defined in the header file `unistd.h' for use as -the HOW argument to the `access' function.

A file begins -with a size of 0 and is automatically extended when data is written past -its end. It is also possible to empty a file completely by an `open' -or `fopen' call. - - However, sometimes it is necessary to _reduce_ the size of a file. -This can be done with the `truncate' and `ftruncate' functions. They -were introduced in BSD Unix. `ftruncate' was later added to POSIX.1. - - Some systems allow you to extend a file (creating holes) with these -functions. This is useful when using memory-mapped I/O (*note -Memory-mapped I/O::), where files are not automatically extended. -However, it is not portable but must be implemented if `mmap' allows -mapping of files (i.e., `_POSIX_MAPPED_FILES' is defined). - - Using these functions on anything other than a regular file gives -_undefined_ results. On many systems, such a call will appear to -succeed, without actually accomplishing anything. - - - Function: int truncate (const char *FILENAME, off_t LENGTH) - The `truncate' function changes the size of FILENAME to LENGTH. - If LENGTH is shorter than the previous length, data at the end - will be lost. The file must be writable by the user to perform - this operation. - - If LENGTH is longer, holes will be added to the end. However, some - systems do not support this feature and will leave the file - unchanged. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `truncate' function is in fact `truncate64' and the type `off_t' - has 64 bits which makes it possible to handle files up to 2^63 - bytes in length. - - The return value is 0 for success, or -1 for an error. In - addition to the usual file name errors, the following errors may - occur: - - `EACCES' - The file is a directory or not writable. - - `EINVAL' - LENGTH is negative. - - `EFBIG' - The operation would extend the file beyond the limits of the - operating system. - - `EIO' - A hardware I/O error occurred. - - `EPERM' - The file is "append-only" or "immutable". - - `EINTR' - The operation was interrupted by a signal. - - - - Function: int truncate64 (const char *NAME, off64_t LENGTH) - This function is similar to the `truncate' function. The - difference is that the LENGTH argument is 64 bits wide even on 32 - bits machines, which allows the handling of files with sizes up to - 2^63 bytes. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' on - a 32 bits machine this function is actually available under the - name `truncate' and so transparently replaces the 32 bits - interface. - - - Function: int ftruncate (int FD, off_t LENGTH) - This is like `truncate', but it works on a file descriptor FD for - an opened file instead of a file name to identify the object. The - file must be opened for writing to successfully carry out the - operation. - - The POSIX standard leaves it implementation defined what happens - if the specified new LENGTH of the file is bigger than the - original size. The `ftruncate' function might simply leave the - file alone and do nothing or it can increase the size to the - desired size. In this later case the extended area should be - zero-filled. So using `ftruncate' is no reliable way to increase - the file size but if it is possible it is probably the fastest - way. The function also operates on POSIX shared memory segments - if these are implemented by the system. - - `ftruncate' is especially useful in combination with `mmap'. - Since the mapped region must have a fixed size one cannot enlarge - the file by writing something beyond the last mapped page. - Instead one has to enlarge the file itself and then remap the file - with the new size. The example below shows how this works. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `ftruncate' function is in fact `ftruncate64' and the type `off_t' - has 64 bits which makes it possible to handle files up to 2^63 - bytes in length. - - The return value is 0 for success, or -1 for an error. The - following errors may occur: - - `EBADF' - FD does not correspond to an open file. - - `EACCES' - FD is a directory or not open for writing. - - `EINVAL' - LENGTH is negative. - - `EFBIG' - The operation would extend the file beyond the limits of the - operating system. - - `EIO' - A hardware I/O error occurred. - - `EPERM' - The file is "append-only" or "immutable". - - `EINTR' - The operation was interrupted by a signal. - - - - Function: int ftruncate64 (int ID, off64_t LENGTH) - This function is similar to the `ftruncate' function. The - difference is that the LENGTH argument is 64 bits wide even on 32 - bits machines which allows the handling of files with sizes up to - 2^63 bytes. - - When the source file is compiled with `_FILE_OFFSET_BITS == 64' on - a 32 bits machine this function is actually available under the - name `ftruncate' and so transparently replaces the 32 bits - interface. - - As announced here is a little example of how to use `ftruncate' in -combination with `mmap': - - int fd; - void *start; - size_t len; - - int - add (off_t at, void *block, size_t size) - { - if (at + size > len) - { - /* Resize the file and remap. */ - size_t ps = sysconf (_SC_PAGESIZE); - size_t ns = (at + size + ps - 1) & ~(ps - 1); - void *np; - if (ftruncate (fd, ns) < 0) - return -1; - np = mmap (NULL, ns, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); - if (np == MAP_FAILED) - return -1; - start = np; - len = ns; - } - memcpy ((char *) start + at, block, size); - return 0; - } - - The function `add' writes a block of memory at an arbitrary position -in the file. If the current size of the file is too small it is -extended. Note the it is extended by a round number of pages. This is -a requirement of `mmap'. The program has to keep track of the real -size, and when it has finished a final `ftruncate' call should set the -real size of the file. - - -File: libc.info, Node: Making Special Files, Next: Temporary Files, Prev: File Attributes, Up: File System Interface - -Making Special Files -==================== - - The `mknod' function is the primitive for making special files, such -as files that correspond to devices. The GNU library includes this -function for compatibility with BSD. - - The prototype for `mknod' is declared in `sys/stat.h'. - - - Function: int mknod (const char *FILENAME, int MODE, int DEV) - The `mknod' function makes a special file with name FILENAME. The - MODE specifies the mode of the file, and may include the various - special file bits, such as `S_IFCHR' (for a character special file) - or `S_IFBLK' (for a block special file). *Note Testing File - Type::. - - The DEV argument specifies which device the special file refers to. - Its exact interpretation depends on the kind of special file being - created. - - The return value is `0' on success and `-1' on error. In addition - to the usual file name errors (*note File Name Errors::), the - following `errno' error conditions are defined for this function: - - `EPERM' - The calling process is not privileged. Only the superuser - can create special files. - - `ENOSPC' - The directory or file system that would contain the new file - is full and cannot be extended. - - `EROFS' - The directory containing the new file can't be modified - because it's on a read-only file system. - - `EEXIST' - There is already a file named FILENAME. If you want to - replace this file, you must remove the old file explicitly - first. - - -File: libc.info, Node: Temporary Files, Prev: Making Special Files, Up: File System Interface - -Temporary Files -=============== - - If you need to use a temporary file in your program, you can use the -`tmpfile' function to open it. Or you can use the `tmpnam' (better: -`tmpnam_r') function to provide a name for a temporary file and then -you can open it in the usual way with `fopen'. - - The `tempnam' function is like `tmpnam' but lets you choose what -directory temporary files will go in, and something about what their -file names will look like. Important for multi-threaded programs is -that `tempnam' is reentrant, while `tmpnam' is not since it returns a -pointer to a static buffer. - - These facilities are declared in the header file `stdio.h'. - - - Function: FILE * tmpfile (void) - This function creates a temporary binary file for update mode, as - if by calling `fopen' with mode `"wb+"'. The file is deleted - automatically when it is closed or when the program terminates. - (On some other ISO C systems the file may fail to be deleted if - the program terminates abnormally). - - This function is reentrant. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `tmpfile64', i.e. the LFS - interface transparently replaces the old interface. - - - Function: FILE * tmpfile64 (void) - This function is similar to `tmpfile', but the stream it returns a - pointer to was opened using `tmpfile64'. Therefore this stream can - be used for files larger then 2^31 bytes on 32-bit machines. - - Please note that the return type is still `FILE *'. There is no - special `FILE' type for the LFS interface. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `tmpfile' - and so transparently replaces the old interface. - - - Function: char * tmpnam (char *RESULT) - This function constructs and returns a valid file name that does - not refer to any existing file. If the RESULT argument is a null - pointer, the return value is a pointer to an internal static - string, which might be modified by subsequent calls and therefore - makes this function non-reentrant. Otherwise, the RESULT argument - should be a pointer to an array of at least `L_tmpnam' characters, - and the result is written into that array. - - It is possible for `tmpnam' to fail if you call it too many times - without removing previously-created files. This is because the - limited length of the temporary file names gives room for only a - finite number of different names. If `tmpnam' fails it returns a - null pointer. - - *Warning:* Between the time the pathname is constructed and the - file is created another process might have created a file with the - same name using `tmpnam', leading to a possible security hole. The - implementation generates names which can hardly be predicted, but - when opening the file you should use the `O_EXCL' flag. Using - `tmpfile' or `mkstemp' is a safe way to avoid this problem. - - - Function: char * tmpnam_r (char *RESULT) - This function is nearly identical to the `tmpnam' function, except - that if RESULT is a null pointer it returns a null pointer. - - This guarantees reentrancy because the non-reentrant situation of - `tmpnam' cannot happen here. - - *Warning*: This function has the same security problems as - `tmpnam'. - - - Macro: int L_tmpnam - The value of this macro is an integer constant expression that - represents the minimum size of a string large enough to hold a - file name generated by the `tmpnam' function. - - - Macro: int TMP_MAX - The macro `TMP_MAX' is a lower bound for how many temporary names - you can create with `tmpnam'. You can rely on being able to call - `tmpnam' at least this many times before it might fail saying you - have made too many temporary file names. - - With the GNU library, you can create a very large number of - temporary file names. If you actually created the files, you - would probably run out of disk space before you ran out of names. - Some other systems have a fixed, small limit on the number of - temporary files. The limit is never less than `25'. - - - Function: char * tempnam (const char *DIR, const char *PREFIX) - This function generates a unique temporary file name. If PREFIX - is not a null pointer, up to five characters of this string are - used as a prefix for the file name. The return value is a string - newly allocated with `malloc', so you should release its storage - with `free' when it is no longer needed. - - Because the string is dynamically allocated this function is - reentrant. - - The directory prefix for the temporary file name is determined by - testing each of the following in sequence. The directory must - exist and be writable. - - * The environment variable `TMPDIR', if it is defined. For - security reasons this only happens if the program is not SUID - or SGID enabled. - - * The DIR argument, if it is not a null pointer. - - * The value of the `P_tmpdir' macro. - - * The directory `/tmp'. - - This function is defined for SVID compatibility. - - *Warning:* Between the time the pathname is constructed and the - file is created another process might have created a file with the - same name using `tempnam', leading to a possible security hole. - The implementation generates names which can hardly be predicted, - but when opening the file you should use the `O_EXCL' flag. Using - `tmpfile' or `mkstemp' is a safe way to avoid this problem. - - - SVID Macro: char * P_tmpdir - This macro is the name of the default directory for temporary - files. - - Older Unix systems did not have the functions just described. -Instead they used `mktemp' and `mkstemp'. Both of these functions work -by modifying a file name template string you pass. The last six -characters of this string must be `XXXXXX'. These six `X's are -replaced with six characters which make the whole string a unique file -name. Usually the template string is something like -`/tmp/PREFIXXXXXXX', and each program uses a unique PREFIX. - - *Note:* Because `mktemp' and `mkstemp' modify the template string, -you _must not_ pass string constants to them. String constants are -normally in read-only storage, so your program would crash when -`mktemp' or `mkstemp' tried to modify the string. - - - Function: char * mktemp (char *TEMPLATE) - The `mktemp' function generates a unique file name by modifying - TEMPLATE as described above. If successful, it returns TEMPLATE - as modified. If `mktemp' cannot find a unique file name, it makes - TEMPLATE an empty string and returns that. If TEMPLATE does not - end with `XXXXXX', `mktemp' returns a null pointer. - - *Warning:* Between the time the pathname is constructed and the - file is created another process might have created a file with the - same name using `mktemp', leading to a possible security hole. The - implementation generates names which can hardly be predicted, but - when opening the file you should use the `O_EXCL' flag. Using - `mkstemp' is a safe way to avoid this problem. - - - Function: int mkstemp (char *TEMPLATE) - The `mkstemp' function generates a unique file name just as - `mktemp' does, but it also opens the file for you with `open' - (*note Opening and Closing Files::). If successful, it modifies - TEMPLATE in place and returns a file descriptor for that file open - for reading and writing. If `mkstemp' cannot create a - uniquely-named file, it returns `-1'. If TEMPLATE does not end - with `XXXXXX', `mkstemp' returns `-1' and does not modify TEMPLATE. - - The file is opened using mode `0600'. If the file is meant to be - used by other users this mode must be changed explicitly. - - Unlike `mktemp', `mkstemp' is actually guaranteed to create a unique -file that cannot possibly clash with any other program trying to create -a temporary file. This is because it works by calling `open' with the -`O_EXCL' flag, which says you want to create a new file and get an -error if the file already exists. - - - Function: char * mkdtemp (char *TEMPLATE) - The `mkdtemp' function creates a directory with a unique name. If - it succeeds, it overwrites TEMPLATE with the name of the - directory, and returns TEMPLATE. As with `mktemp' and `mkstemp', - TEMPLATE should be a string ending with `XXXXXX'. - - If `mkdtemp' cannot create an uniquely named directory, it returns - `NULL' and sets ERRNO appropriately. If TEMPLATE does not end - with `XXXXXX', `mkdtemp' returns `NULL' and does not modify - TEMPLATE. ERRNO will be set to `EINVAL' in this case. - - The directory is created using mode `0700'. - - The directory created by `mkdtemp' cannot clash with temporary files -or directories created by other users. This is because directory -creation always works like `open' with `O_EXCL'. *Note Creating -Directories::. - - The `mkdtemp' function comes from OpenBSD. - - -File: libc.info, Node: Pipes and FIFOs, Next: Sockets, Prev: File System Interface, Up: Top - -Pipes and FIFOs -*************** - - A "pipe" is a mechanism for interprocess communication; data written -to the pipe by one process can be read by another process. The data is -handled in a first-in, first-out (FIFO) order. The pipe has no name; it -is created for one use and both ends must be inherited from the single -process which created the pipe. - - A "FIFO special file" is similar to a pipe, but instead of being an -anonymous, temporary connection, a FIFO has a name or names like any -other file. Processes open the FIFO by name in order to communicate -through it. - - A pipe or FIFO has to be open at both ends simultaneously. If you -read from a pipe or FIFO file that doesn't have any processes writing -to it (perhaps because they have all closed the file, or exited), the -read returns end-of-file. Writing to a pipe or FIFO that doesn't have a -reading process is treated as an error condition; it generates a -`SIGPIPE' signal, and fails with error code `EPIPE' if the signal is -handled or blocked. - - Neither pipes nor FIFO special files allow file positioning.

This -creates both the reading and writing ends of the pipe. It is not very -useful for a single process to use a pipe to talk to itself. In typical -use, a process creates a pipe just before it forks one or more child -processes (*note Creating a Process::). The pipe is then used for -communication either between the parent or child processes, or between -two sibling processes. - - The `pipe' function is declared in the header file `unistd.h'. - - - Function: int pipe (int FILEDES[2]) - The `pipe' function creates a pipe and puts the file descriptors - for the reading and writing ends of the pipe (respectively) into - `FILEDES[0]' and `FILEDES[1]'. - - An easy way to remember that the input end comes first is that file - descriptor `0' is standard input, and file descriptor `1' is - standard output. - - If successful, `pipe' returns a value of `0'. On failure, `-1' is - returned. The following `errno' error conditions are defined for - this function: - - `EMFILE' - The process has too many files open. - - `ENFILE' - There are too many open files in the entire system. *Note - Error Codes::, for more information about `ENFILE'. This - error never occurs in the GNU system. - - Here is an example of a simple program that creates a pipe. This -program uses the `fork' function (*note Creating a Process::) to create -a child process.

One way of doing this is by using a -combination of `pipe' (to create the pipe), `fork' (to create the -subprocess), `dup2' (to force the subprocess to use the pipe as its -standard input or output channel), and `exec' (to execute the new -program). Or, you can use `popen' and `pclose'. - - The advantage of using `popen' and `pclose' is that the interface is -much simpler and easier to use. But it doesn't offer as much -flexibility as using the low-level functions directly. - - - Function: FILE * popen (const char *COMMAND, const char *MODE) - The `popen' function is closely related to the `system' function; - see *Note Running a Command::. It executes the shell command - COMMAND as a subprocess. However, instead of waiting for the - command to complete, it creates a pipe to the subprocess and - returns a stream that corresponds to that pipe. - - If you specify a MODE argument of `"r"', you can read from the - stream to retrieve data from the standard output channel of the - subprocess. The subprocess inherits its standard input channel - from the parent process. - - Similarly, if you specify a MODE argument of `"w"', you can write - to the stream to send data to the standard input channel of the - subprocess. The subprocess inherits its standard output channel - from the parent process. - - In the event of an error `popen' returns a null pointer. This - might happen if the pipe or stream cannot be created, if the - subprocess cannot be forked, or if the program cannot be executed. - - - Function: int pclose (FILE *STREAM) - The `pclose' function is used to close a stream created by `popen'. - It waits for the child process to terminate and returns its status - value, as for the `system' function. - - Here is an example showing how to use `popen' and `pclose' to filter -output through another program, in this case the paging program `more'. - - #include - #include - - void - write_data (FILE * stream) - { - int i; - for (i = 0; i < 100; i++) - fprintf (stream, "%d\n", i); - if (ferror (stream)) - { - fprintf (stderr, "Output to stream failed.\n"); - exit (EXIT_FAILURE); - } - } - - int - main (void) - { - FILE *output; - - output = popen ("more", "w"); - if (!output) - { - fprintf (stderr, - "incorrect parameters or too many files.\n"); - return EXIT_FAILURE; - } - write_data (output); - if (pclose (output) != 0) - { - fprintf (stderr, - "Could not run more or other error.\n"); - } - return EXIT_SUCCESS; - } - - -File: libc.info, Node: FIFO Special Files, Next: Pipe Atomicity, Prev: Pipe to a Subprocess, Up: Pipes and FIFOs - -FIFO Special Files -================== - - A FIFO special file is similar to a pipe, except that it is created -in a different way. Instead of being an anonymous communications -channel, a FIFO special file is entered into the file system by calling -`mkfifo'. - - Once you have created a FIFO special file in this way, any process -can open it for reading or writing, in the same way as an ordinary file. -However, it has to be open at both ends simultaneously before you can -proceed to do any input or output operations on it. Opening a FIFO for -reading normally blocks until some other process opens the same FIFO for -writing, and vice versa. - - The `mkfifo' function is declared in the header file `sys/stat.h'. - - - Function: int mkfifo (const char *FILENAME, mode_t MODE) - The `mkfifo' function makes a FIFO special file with name - FILENAME. The MODE argument is used to set the file's - permissions; see *Note Setting Permissions::. - - The normal, successful return value from `mkfifo' is `0'. In the - case of an error, `-1' is returned. In addition to the usual file - name errors (*note File Name Errors::), the following `errno' - error conditions are defined for this function: - - `EEXIST' - The named file already exists. - - `ENOSPC' - The directory or file system cannot be extended. - - `EROFS' - The directory that would contain the file resides on a - read-only file system. - - -File: libc.info, Node: Pipe Atomicity, Prev: FIFO Special Files, Up: Pipes and FIFOs - -Atomicity of Pipe I/O -===================== - - Reading or writing pipe data is "atomic" if the size of data written -is not greater than `PIPE_BUF'. This means that the data transfer -seems to be an instantaneous unit, in that nothing else in the system -can observe a state in which it is partially complete. Atomic I/O may -not begin right away (it may need to wait for buffer space or for data), -but once it does begin it finishes immediately. - - Reading or writing a larger amount of data may not be atomic; for -example, output data from other processes sharing the descriptor may be -interspersed. Also, once `PIPE_BUF' characters have been written, -further writes will block until some characters are read. - - *Note Limits for Files::, for information about the `PIPE_BUF' -parameter. - - -File: libc.info, Node: Sockets, Next: Low-Level Terminal Interface, Prev: Pipes and FIFOs, Up: Top - -Sockets -******* - - This chapter describes the GNU facilities for interprocess -communication using sockets. - - A "socket" is a generalized interprocess communication channel. -Like a pipe, a socket is represented as a file descriptor. Unlike pipes -sockets support communication between unrelated processes, and even -between processes running on different machines that communicate over a -network. Sockets are the primary means of communicating with other -machines; `telnet', `rlogin', `ftp', `talk' and the other familiar -network programs use sockets. - - Not all operating systems support sockets. In the GNU library, the -header file `sys/socket.h' exists regardless of the operating system, -and the socket functions always exist, but if the system does not -really support sockets these functions always fail. - - *Incomplete:* We do not currently document the facilities for -broadcast messages or for configuring Internet interfaces. The -reentrant functions and some newer functions that are related to IPv6 -aren't documented either so far. - -* Menu: - -* Socket Concepts:: Basic concepts you need to know about. -* Communication Styles::Stream communication, datagrams and other styles. -* Socket Addresses:: How socket names (``addresses'') work. -* Interface Naming:: Identifying specific network interfaces. -* Local Namespace:: Details about the local namespace. -* Internet Namespace:: Details about the Internet namespace. -* Misc Namespaces:: Other namespaces not documented fully here. -* Open/Close Sockets:: Creating sockets and destroying them. -* Connections:: Operations on sockets with connection state. -* Datagrams:: Operations on datagram sockets. -* Inetd:: Inetd is a daemon that starts servers on request. - The most convenient way to write a server - is to make it work with Inetd. -* Socket Options:: Miscellaneous low-level socket options. -* Networks Database:: Accessing the database of network names. - - -File: libc.info, Node: Socket Concepts, Next: Communication Styles, Up: Sockets - -Socket Concepts -=============== - - When you create a socket, you must specify the style of communication -you want to use and the type of protocol that should implement it. The -"communication style" of a socket defines the user-level semantics of -sending and receiving data on the socket. Choosing a communication -style specifies the answers to questions such as these: - - * *What are the units of data transmission?* Some communication - styles regard the data as a sequence of bytes with no larger - structure; others group the bytes into records (which are known in - this context as "packets"). - - * *Can data be lost during normal operation?* Some communication - styles guarantee that all the data sent arrives in the order it was - sent (barring system or network crashes); other styles occasionally - lose data as a normal part of operation, and may sometimes deliver - packets more than once or in the wrong order. - - Designing a program to use unreliable communication styles usually - involves taking precautions to detect lost or misordered packets - and to retransmit data as needed. - - * *Is communication entirely with one partner?* Some communication - styles are like a telephone call--you make a "connection" with one - remote socket and then exchange data freely. Other styles are - like mailing letters--you specify a destination address for each - message you send. - - You must also choose a "namespace" for naming the socket. A socket -name ("address") is meaningful only in the context of a particular -namespace. In fact, even the data type to use for a socket name may -depend on the namespace. Namespaces are also called "domains", but we -avoid that word as it can be confused with other usage of the same -term. Each namespace has a symbolic name that starts with `PF_'. A -corresponding symbolic name starting with `AF_' designates the address -format for that namespace. - - Finally you must choose the "protocol" to carry out the -communication. The protocol determines what low-level mechanism is used -to transmit and receive data. Each protocol is valid for a particular -namespace and communication style; a namespace is sometimes called a -"protocol family" because of this, which is why the namespace names -start with `PF_'. - - The rules of a protocol apply to the data passing between two -programs, perhaps on different computers; most of these rules are -handled by the operating system and you need not know about them. What -you do need to know about protocols is this: - - * In order to have communication between two sockets, they must - specify the _same_ protocol. - - * Each protocol is meaningful with particular style/namespace - combinations and cannot be used with inappropriate combinations. - For example, the TCP protocol fits only the byte stream style of - communication and the Internet namespace. - - * For each combination of style and namespace there is a "default - protocol", which you can request by specifying 0 as the protocol - number. And that's what you should normally do--use the default. - - Throughout the following description at various places -variables/parameters to denote sizes are required. And here the trouble -starts. In the first implementations the type of these variables was -simply `int'. On most machines at that time an `int' was 32 bits wide, -which created a _de facto_ standard requiring 32-bit variables. This -is important since references to variables of this type are passed to -the kernel. - - Then the POSIX people came and unified the interface with the words -"all size values are of type `size_t'". On 64-bit machines `size_t' is -64 bits wide, so pointers to variables were no longer possible. - - The Unix98 specification provides a solution by introducing a type -`socklen_t'. This type is used in all of the cases that POSIX changed -to use `size_t'. The only requirement of this type is that it be an -unsigned type of at least 32 bits. Therefore, implementations which -require that references to 32-bit variables be passed can be as happy -as implementations which use 64-bit values. - - -File: libc.info, Node: Communication Styles, Next: Socket Addresses, Prev: Socket Concepts, Up: Sockets - -Communication Styles -==================== - - The GNU library includes support for several different kinds of -sockets, each with different characteristics. This section describes -the supported socket types. The symbolic constants listed here are -defined in `sys/socket.h'. - - - Macro: int SOCK_STREAM - The `SOCK_STREAM' style is like a pipe (*note Pipes and FIFOs::). - It operates over a connection with a particular remote socket and - transmits data reliably as a stream of bytes. - - Use of this style is covered in detail in *Note Connections::. - - - Macro: int SOCK_DGRAM - The `SOCK_DGRAM' style is used for sending individually-addressed - packets unreliably. It is the diametrical opposite of - `SOCK_STREAM'. - - Each time you write data to a socket of this kind, that data - becomes one packet. Since `SOCK_DGRAM' sockets do not have - connections, you must specify the recipient address with each - packet. - - The only guarantee that the system makes about your requests to - transmit data is that it will try its best to deliver each packet - you send. It may succeed with the sixth packet after failing with - the fourth and fifth packets; the seventh packet may arrive before - the sixth, and may arrive a second time after the sixth. - - The typical use for `SOCK_DGRAM' is in situations where it is - acceptable to simply re-send a packet if no response is seen in a - reasonable amount of time. - - *Note Datagrams::, for detailed information about how to use - datagram sockets. - - - Macro: int SOCK_RAW - This style provides access to low-level network protocols and - interfaces. Ordinary user programs usually have no need to use - this style. - - -File: libc.info, Node: Socket Addresses, Next: Interface Naming, Prev: Communication Styles, Up: Sockets - -Socket Addresses -================ - - The name of a socket is normally called an "address". The functions -and symbols for dealing with socket addresses were named -inconsistently, sometimes using the term "name" and sometimes using -"address". You can regard these terms as synonymous where sockets are -concerned. - - A socket newly created with the `socket' function has no address. -Other processes can find it for communication only if you give it an -address. We call this "binding" the address to the socket, and the way -to do it is with the `bind' function. - - You need be concerned with the address of a socket if other processes -are to find it and start communicating with it. You can specify an -address for other sockets, but this is usually pointless; the first time -you send data from a socket, or use it to initiate a connection, the -system assigns an address automatically if you have not specified one. - - Occasionally a client needs to specify an address because the server -discriminates based on address; for example, the rsh and rlogin -protocols look at the client's socket address and only bypass password -checking if it is less than `IPPORT_RESERVED' (*note Ports::). - - The details of socket addresses vary depending on what namespace you -are using. *Note Local Namespace::, or *Note Internet Namespace::, for -specific information. - - Regardless of the namespace, you use the same functions `bind' and -`getsockname' to set and examine a socket's address.

You -can't use this data type effectively to interpret an address or -construct one; for that, you must use the proper data type for the -socket's namespace. - - Thus, the usual practice is to construct an address of the proper -namespace-specific type, then cast a pointer to `struct sockaddr *' -when you call `bind' or `getsockname'. - - The one piece of information that you can get from the `struct -sockaddr' data type is the "address format designator". This tells you -which data type to use to understand the address fully. - - The symbols in this section are defined in the header file -`sys/socket.h'. - - - Data Type: struct sockaddr - The `struct sockaddr' type itself has the following members: - - `short int sa_family' - This is the code for the address format of this address. It - identifies the format of the data which follows. - - `char sa_data[14]' - This is the actual socket address data, which is - format-dependent. Its length also depends on the format, and - may well be more than 14. The length 14 of `sa_data' is - essentially arbitrary. - - Each address format has a symbolic name which starts with `AF_'. -Each of them corresponds to a `PF_' symbol which designates the -corresponding namespace. Here is a list of address format names: - -`AF_LOCAL' - This designates the address format that goes with the local - namespace. (`PF_LOCAL' is the name of that namespace.) *Note - Local Namespace Details::, for information about this address - format. - -`AF_UNIX' - This is a synonym for `AF_LOCAL'. Although `AF_LOCAL' is mandated - by POSIX.1g, `AF_UNIX' is portable to more systems. `AF_UNIX' was - the traditional name stemming from BSD, so even most POSIX systems - support it. It is also the name of choice in the Unix98 - specification. (The same is true for `PF_UNIX' vs. `PF_LOCAL'). - -`AF_FILE' - This is another synonym for `AF_LOCAL', for compatibility. - (`PF_FILE' is likewise a synonym for `PF_LOCAL'.) - -`AF_INET' - This designates the address format that goes with the Internet - namespace. (`PF_INET' is the name of that namespace.) *Note - Internet Address Formats::. - -`AF_INET6' - This is similar to `AF_INET', but refers to the IPv6 protocol. - (`PF_INET6' is the name of the corresponding namespace.) - -`AF_UNSPEC' - This designates no particular address format. It is used only in - rare cases, such as to clear out the default destination address - of a "connected" datagram socket. *Note Sending Datagrams::. - - The corresponding namespace designator symbol `PF_UNSPEC' exists - for completeness, but there is no reason to use it in a program. - - `sys/socket.h' defines symbols starting with `AF_' for many -different kinds of networks, most or all of which are not actually -implemented.

You can -specify any file name you want as the address of the socket, but you -must have write permission on the directory containing it. It's common -to put these files in the `/tmp' directory. - - One peculiarity of the local namespace is that the name is only used -when opening the connection; once open the address is not meaningful and -may not exist. - - Another peculiarity is that you cannot connect to such a socket from -another machine-not even if the other machine shares the file system -which contains the name of the socket. You can see the socket in a -directory listing, but connecting to it never succeeds. Some programs -take advantage of this, such as by asking the client to send its own -process ID, and using the process IDs to distinguish between clients. -However, we recommend you not use this method in protocols you design, -as we might someday permit connections from other machines that mount -the same file systems. Instead, send each new client an identifying -number if you want it to have one. - - After you close a socket in the local namespace, you should delete -the file name from the file system. Use `unlink' or `remove' to do -this; see *Note Deleting Files::. - - The local namespace supports just one protocol for any communication -style; it is protocol number `0'. - - -File: libc.info, Node: Local Namespace Details, Next: Local Socket Example, Prev: Local Namespace Concepts, Up: Local Namespace - -Details of Local Namespace --------------------------- - - To create a socket in the local namespace, use the constant -`PF_LOCAL' as the NAMESPACE argument to `socket' or `socketpair'.

RMS suggests making - this a zero-length array and tweaking the following example - to use `alloca' to allocate an appropriate amount of storage - based on the length of the filename. - - You should compute the LENGTH parameter for a socket address in the -local namespace as the sum of the size of the `sun_family' component -and the string length (_not_ the allocation size!) of the file name -string.

Historically these are divided into two parts, a "network -number" and a "local network address number" within that network. In -the mid-1990s classless addresses were introduced which changed this -behavior. Since some functions implicitly expect the old definitions, -we first describe the class-based network and will then describe -classless addresses. IPv6 uses only classless addresses and therefore -the following paragraphs don't apply. - - The class-based IPv4 network number consists of the first one, two or -three bytes; the rest of the bytes are the local address. - - IPv4 network numbers are registered with the Network Information -Center (NIC), and are divided into three classes--A, B and C. The local -network address numbers of individual machines are registered with the -administrator of the particular network. - - Class A networks have single-byte numbers in the range 0 to 127. -There are only a small number of Class A networks, but they can each -support a very large number of hosts. Medium-sized Class B networks -have two-byte network numbers, with the first byte in the range 128 to -191. Class C networks are the smallest; they have three-byte network -numbers, with the first byte in the range 192-255. Thus, the first 1, -2, or 3 bytes of an Internet address specify a network. The remaining -bytes of the Internet address specify the address within that network. - - The Class A network 0 is reserved for broadcast to all networks. In -addition, the host number 0 within each network is reserved for -broadcast to all hosts in that network. These uses are obsolete now -but for compatibility reasons you shouldn't use network 0 and host -number 0. - - The Class A network 127 is reserved for loopback; you can always use -the Internet address `127.0.0.1' to refer to the host machine. - - Since a single machine can be a member of multiple networks, it can -have multiple Internet host addresses. However, there is never -supposed to be more than one machine with the same host address. - - There are four forms of the "standard numbers-and-dots notation" for -Internet addresses: - -`A.B.C.D' - This specifies all four bytes of the address individually and is - the commonly used representation. - -`A.B.C' - The last part of the address, C, is interpreted as a 2-byte - quantity. This is useful for specifying host addresses in a Class - B network with network address number `A.B'. - -`A.B' - The last part of the address, B, is interpreted as a 3-byte - quantity. This is useful for specifying host addresses in a Class - A network with network address number A. - -`A' - If only one part is given, this corresponds directly to the host - address number. - - Within each part of the address, the usual C conventions for -specifying the radix apply. In other words, a leading `0x' or `0X' -implies hexadecimal radix; a leading `0' implies octal; and otherwise -decimal radix is assumed. - -Classless Addresses -................... - - IPv4 addresses (and IPv6 addresses also) are now considered -classless; the distinction between classes A, B and C can be ignored. -Instead an IPv4 host address consists of a 32-bit address and a 32-bit -mask. The mask contains set bits for the network part and cleared bits -for the host part. The network part is contiguous from the left, with -the remaining bits representing the host. As a consequence, the -netmask can simply be specified as the number of set bits. Classes A, -B and C are just special cases of this general rule. For example, -class A addresses have a netmask of `255.0.0.0' or a prefix length of 8. - - Classless IPv4 network addresses are written in numbers-and-dots -notation with the prefix length appended and a slash as separator. For -example the class A network 10 is written as `10.0.0.0/8'. - -IPv6 Addresses -.............. - - IPv6 addresses contain 128 bits (IPv4 has 32 bits) of data. A host -address is usually written as eight 16-bit hexadecimal numbers that are -separated by colons. Two colons are used to abbreviate strings of -consecutive zeros. For example, the IPv6 loopback address -`0:0:0:0:0:0:0:1' can just be written as `::1'. - - -File: libc.info, Node: Host Address Data Type, Next: Host Address Functions, Prev: Abstract Host Addresses, Up: Host Addresses - -Host Address Data Type -...................... - - IPv4 Internet host addresses are represented in some contexts as -integers (type `uint32_t'). In other contexts, the integer is packaged -inside a structure of type `struct in_addr'. It would be better if the -usage were made consistent, but it is not hard to extract the integer -from the structure or put the integer into a structure. - - You will find older code that uses `unsigned long int' for IPv4 -Internet host addresses instead of `uint32_t' or `struct in_addr'. -Historically `unsigned long int' was a 32-bit number but with 64-bit -machines this has changed. Using `unsigned long int' might break the -code if it is used on machines where this type doesn't have 32 bits. -`uint32_t' is specified by Unix98 and guaranteed to have 32 bits. - - IPv6 Internet host addresses have 128 bits and are packaged inside a -structure of type `struct in6_addr'. - - The following basic definitions for Internet addresses are declared -in the header file `netinet/in.h': - - - Data Type: struct in_addr - This data type is used in certain contexts to contain an IPv4 - Internet host address. It has just one field, named `s_addr', - which records the host address number as an `uint32_t'. - - - Macro: uint32_t INADDR_LOOPBACK - You can use this constant to stand for "the address of this - machine," instead of finding its actual address. It is the IPv4 - Internet address `127.0.0.1', which is usually called `localhost'. - This special constant saves you the trouble of looking up the - address of your own machine. Also, the system usually implements - `INADDR_LOOPBACK' specially, avoiding any network traffic for the - case of one machine talking to itself. - - - Macro: uint32_t INADDR_ANY - You can use this constant to stand for "any incoming address" when - binding to an address. *Note Setting Address::.

If the input - is not valid, `inet_addr' returns `INADDR_NONE'. This is an - obsolete interface to `inet_aton', described immediately above. It - is obsolete because `INADDR_NONE' is a valid address - (255.255.255.255), and `inet_aton' provides a cleaner way to - indicate error return. - - - Function: uint32_t inet_network (const char *NAME) - This function extracts the network number from the address NAME, - given in the standard numbers-and-dots notation. The returned - address is in host order. If the input is not valid, - `inet_network' returns `-1'. - - The function works only with traditional IPv4 class A, B and C - network types. It doesn't work with classless addresses and - shouldn't be used anymore. - - - Function: char * inet_ntoa (struct in_addr ADDR) - This function converts the IPv4 Internet host address ADDR to a - string in the standard numbers-and-dots notation. The return - value is a pointer into a statically-allocated buffer. Subsequent - calls will overwrite the same buffer, so you should copy the - string if you need to save it. - - In multi-threaded programs each thread has an own - statically-allocated buffer. But still subsequent calls of - `inet_ntoa' in the same thread will overwrite the result of the - last call. - - Instead of `inet_ntoa' the newer function `inet_ntop' which is - described below should be used since it handles both IPv4 and IPv6 - addresses. - - - Function: struct in_addr inet_makeaddr (uint32_t NET, uint32_t LOCAL) - This function makes an IPv4 Internet host address by combining the - network number NET with the local-address-within-network number - LOCAL. - - - Function: uint32_t inet_lnaof (struct in_addr ADDR) - This function returns the local-address-within-network part of the - Internet host address ADDR. - - The function works only with traditional IPv4 class A, B and C - network types.

It doesn't work with classless addresses and - shouldn't be used anymore. - - - Function: int inet_pton (int AF, const char *CP, void *BUF) - This function converts an Internet address (either IPv4 or IPv6) - from presentation (textual) to network (binary) format. AF should - be either `AF_INET' or `AF_INET6', as appropriate for the type of - address being converted. CP is a pointer to the input string, and - BUF is a pointer to a buffer for the result. It is the caller's - responsibility to make sure the buffer is large enough. - - - Function: const char * inet_ntop (int AF, const void *CP, char *BUF, - size_t LEN) - This function converts an Internet address (either IPv4 or IPv6) - from network (binary) to presentation (textual) form. AF should be - either `AF_INET' or `AF_INET6', as appropriate. CP is a pointer - to the address to be converted. BUF should be a pointer to a - buffer to hold the result, and LEN is the length of this buffer. - The return value from the function will be this buffer address. - - -File: libc.info, Node: Host Names, Prev: Host Address Functions, Up: Host Addresses - -Host Names -.......... - - Besides the standard numbers-and-dots notation for Internet -addresses, you can also refer to a host by a symbolic name. The -advantage of a symbolic name is that it is usually easier to remember. -For example, the machine with Internet address `158.121.106.19' is also -known as `alpha.gnu.org'; and other machines in the `gnu.org' domain -can refer to it simply as `alpha'. - - Internally, the system uses a database to keep track of the mapping -between host names and host numbers. This database is usually either -the file `/etc/hosts' or an equivalent provided by a name server. The -functions and other symbols for accessing this database are declared in -`netdb.h'. They are BSD features, defined unconditionally if you -include `netdb.h'. - - - Data Type: struct hostent - This data type is used to represent an entry in the hosts - database. It has the following members: - - `char *h_name' - This is the "official" name of the host. - - `char **h_aliases' - These are alternative names for the host, represented as a - null-terminated vector of strings. - - `int h_addrtype' - This is the host address type; in practice, its value is - always either `AF_INET' or `AF_INET6', with the latter being - used for IPv6 hosts. In principle other kinds of addresses - could be represented in the database as well as Internet - addresses; if this were done, you might find a value in this - field other than `AF_INET' or `AF_INET6'. *Note Socket - Addresses::. - - `int h_length' - This is the length, in bytes, of each address. - - `char **h_addr_list' - This is the vector of addresses for the host. (Recall that - the host might be connected to multiple networks and have - different addresses on each one.) The vector is terminated - by a null pointer. - - `char *h_addr' - This is a synonym for `h_addr_list[0]'; in other words, it is - the first host address. - - As far as the host database is concerned, each address is just a -block of memory `h_length' bytes long. But in other contexts there is -an implicit assumption that you can convert IPv4 addresses to a `struct -in_addr' or an `uint32_t'. Host addresses in a `struct hostent' -structure are always given in network byte order; see *Note Byte -Order::. - - You can use `gethostbyname', `gethostbyname2' or `gethostbyaddr' to -search the hosts database for information about a particular host. The -information is returned in a statically-allocated structure; you must -copy the information if you need to save it across calls. You can also -use `getaddrinfo' and `getnameinfo' to obtain this information. - - - Function: struct hostent * gethostbyname (const char *NAME) - The `gethostbyname' function returns information about the host - named NAME. If the lookup fails, it returns a null pointer. - - - Function: struct hostent * gethostbyname2 (const char *NAME, int AF) - The `gethostbyname2' function is like `gethostbyname', but allows - the caller to specify the desired address family (e.g. `AF_INET' - or `AF_INET6') of the result. - - - Function: struct hostent * gethostbyaddr (const char *ADDR, size_t - LENGTH, int FORMAT) - The `gethostbyaddr' function returns information about the host - with Internet address ADDR. The parameter ADDR is not really a - pointer to char - it can be a pointer to an IPv4 or an IPv6 - address. The LENGTH argument is the size (in bytes) of the address - at ADDR. FORMAT specifies the address format; for an IPv4 - Internet address, specify a value of `AF_INET'; for an IPv6 - Internet address, use `AF_INET6'. - - If the lookup fails, `gethostbyaddr' returns a null pointer. - - If the name lookup by `gethostbyname' or `gethostbyaddr' fails, you -can find out the reason by looking at the value of the variable -`h_errno'. (It would be cleaner design for these functions to set -`errno', but use of `h_errno' is compatible with other systems.) - - Here are the error codes that you may find in `h_errno': - -`HOST_NOT_FOUND' - No such host is known in the database. - -`TRY_AGAIN' - This condition happens when the name server could not be - contacted. If you try again later, you may succeed then. - -`NO_RECOVERY' - A non-recoverable error occurred. - -`NO_ADDRESS' - The host database contains an entry for the name, but it doesn't - have an associated Internet address. - - The lookup functions above all have one in common: they are not -reentrant and therefore unusable in multi-threaded applications. -Therefore provides the GNU C library a new set of functions which can be -used in this context. - - - Function: int gethostbyname_r (const char *restrict NAME, struct - hostent *restrict RESULT_BUF, char *restrict BUF, size_t - BUFLEN, struct hostent **restrict RESULT, int *restrict - H_ERRNOP) - The `gethostbyname_r' function returns information about the host - named NAME. The caller must pass a pointer to an object of type - `struct hostent' in the RESULT_BUF parameter. In addition the - function may need extra buffer space and the caller must pass an - pointer and the size of the buffer in the BUF and BUFLEN - parameters. - - A pointer to the buffer, in which the result is stored, is - available in `*RESULT' after the function call successfully - returned. If an error occurs or if no entry is found, the pointer - `*RESULT' is a null pointer. Success is signalled by a zero - return value. If the function failed the return value is an error - number. In addition to the errors defined for `gethostbyname' it - can also be `ERANGE'. In this case the call should be repeated - with a larger buffer. Additional error information is not stored - in the global variable `h_errno' but instead in the object pointed - to by H_ERRNOP. - - Here's a small example: - struct hostent * - gethostname (char *host) - { - struct hostent hostbuf, *hp; - size_t hstbuflen; - char *tmphstbuf; - int res; - int herr; - - hstbuflen = 1024; - /* Allocate buffer, remember to free it to avoid memory leakage. */ - tmphstbuf = malloc (hstbuflen); - - while ((res = gethostbyname_r (host, &hostbuf, tmphstbuf, hstbuflen, - &hp, &herr)) == ERANGE) - { - /* Enlarge the buffer. */ - hstbuflen *= 2; - tmphstbuf = realloc (tmphstbuf, hstbuflen); - } - /* Check for errors. */ - if (res || hp == NULL) - return NULL; - return hp; - } - - - Function: int gethostbyname2_r (const char *NAME, int AF, struct - hostent *restrict RESULT_BUF, char *restrict BUF, size_t - BUFLEN, struct hostent **restrict RESULT, int *restrict - H_ERRNOP) - The `gethostbyname2_r' function is like `gethostbyname_r', but - allows the caller to specify the desired address family (e.g. - `AF_INET' or `AF_INET6') for the result. - - - Function: int gethostbyaddr_r (const char *ADDR, size_t LENGTH, int - FORMAT, struct hostent *restrict RESULT_BUF, char *restrict - BUF, size_t BUFLEN, struct hostent **restrict RESULT, int - *restrict H_ERRNOP) - The `gethostbyaddr_r' function returns information about the host - with Internet address ADDR. The parameter ADDR is not really a - pointer to char - it can be a pointer to an IPv4 or an IPv6 - address. The LENGTH argument is the size (in bytes) of the address - at ADDR. FORMAT specifies the address format; for an IPv4 - Internet address, specify a value of `AF_INET'; for an IPv6 - Internet address, use `AF_INET6'. - - Similar to the `gethostbyname_r' function, the caller must provide - buffers for the result and memory used internally. In case of - success the function returns zero. Otherwise the value is an - error number where `ERANGE' has the special meaning that the - caller-provided buffer is too small. - - You can also scan the entire hosts database one entry at a time using -`sethostent', `gethostent' and `endhostent'. Be careful when using -these functions because they are not reentrant. - - - Function: void sethostent (int STAYOPEN) - This function opens the hosts database to begin scanning it. You - can then call `gethostent' to read the entries. - - If the STAYOPEN argument is nonzero, this sets a flag so that - subsequent calls to `gethostbyname' or `gethostbyaddr' will not - close the database (as they usually would). This makes for more - efficiency if you call those functions several times, by avoiding - reopening the database for each call. - - - Function: struct hostent * gethostent (void) - This function returns the next entry in the hosts database. It - returns a null pointer if there are no more entries. - - - Function: void endhostent (void) - This function closes the hosts database. - - -File: libc.info, Node: Ports, Next: Services Database, Prev: Protocols Database, Up: Internet Namespace - -Internet Ports --------------- - - A socket address in the Internet namespace consists of a machine's -Internet address plus a "port number" which distinguishes the sockets -on a given machine (for a given protocol). Port numbers range from 0 -to 65,535. - - Port numbers less than `IPPORT_RESERVED' are reserved for standard -servers, such as `finger' and `telnet'. There is a database that keeps -track of these, and you can use the `getservbyname' function to map a -service name onto a port number; see *Note Services Database::. - - If you write a server that is not one of the standard ones defined in -the database, you must choose a port number for it. Use a number -greater than `IPPORT_USERRESERVED'; such numbers are reserved for -servers and won't ever be generated automatically by the system. -Avoiding conflicts with servers being run by other users is up to you. - - When you use a socket without specifying its address, the system -generates a port number for it. This number is between -`IPPORT_RESERVED' and `IPPORT_USERRESERVED'. - - On the Internet, it is actually legitimate to have two different -sockets with the same port number, as long as they never both try to -communicate with the same socket address (host address plus port -number). You shouldn't duplicate a port number except in special -circumstances where a higher-level protocol requires it. Normally, the -system won't let you do it; `bind' normally insists on distinct port -numbers. To reuse a port number, you must set the socket option -`SO_REUSEADDR'. *Note Socket-Level Options::. - - These macros are defined in the header file `netinet/in.h'. - - - Macro: int IPPORT_RESERVED - Port numbers less than `IPPORT_RESERVED' are reserved for - superuser use. - - - Macro: int IPPORT_USERRESERVED - Port numbers greater than or equal to `IPPORT_USERRESERVED' are - reserved for explicit use; they will never be allocated - automatically. - - -File: libc.info, Node: Services Database, Next: Byte Order, Prev: Ports, Up: Internet Namespace - -The Services Database ---------------------- - - The database that keeps track of "well-known" services is usually -either the file `/etc/services' or an equivalent from a name server. -You can use these utilities, declared in `netdb.h', to access the -services database. - - - Data Type: struct servent - This data type holds information about entries from the services - database. It has the following members: - - `char *s_name' - This is the "official" name of the service. - - `char **s_aliases' - These are alternate names for the service, represented as an - array of strings.

Some computers put the most -significant byte within a word first (this is called "big-endian" -order), and others put it last ("little-endian" order). - - So that machines with different byte order conventions can -communicate, the Internet protocols specify a canonical byte order -convention for data transmitted over the network. This is known as -"network byte order". - - When establishing an Internet socket connection, you must make sure -that the data in the `sin_port' and `sin_addr' members of the -`sockaddr_in' structure are represented in network byte order. If you -are encoding integer data in the messages sent through the socket, you -should convert this to network byte order too. If you don't do this, -your program may fail when running on or talking to other kinds of -machines. - - If you use `getservbyname' and `gethostbyname' or `inet_addr' to get -the port number and host address, the values are already in network -byte order, and you can copy them directly into the `sockaddr_in' -structure. - - Otherwise, you have to convert the values explicitly. Use `htons' -and `ntohs' to convert values for the `sin_port' member. Use `htonl' -and `ntohl' to convert IPv4 addresses for the `sin_addr' member. -(Remember, `struct in_addr' is equivalent to `uint32_t'.)

For example, the protocol implements -things like checksums to detect errors in transmissions, and routing -instructions for messages. Normal user programs have little reason to -mess with these details directly. - - The default communications protocol for the Internet namespace -depends on the communication style. For stream communication, the -default is TCP ("transmission control protocol"). For datagram -communication, the default is UDP ("user datagram protocol"). For -reliable datagram communication, the default is RDP ("reliable datagram -protocol"). You should nearly always use the default. - - Internet protocols are generally specified by a name instead of a -number. The network protocols that a host knows about are stored in a -database. This is usually either derived from the file -`/etc/protocols', or it may be an equivalent provided by a name server. -You look up the protocol number associated with a named protocol in -the database using the `getprotobyname' function. - - Here are detailed descriptions of the utilities for accessing the -protocols database.

The NAMESPACE argument specifies the - namespace; it must be `PF_LOCAL' (*note Local Namespace::) or - `PF_INET' (*note Internet Namespace::). PROTOCOL designates the - specific protocol (*note Socket Concepts::); zero is usually right - for PROTOCOL. - - The return value from `socket' is the file descriptor for the new - socket, or `-1' in case of error. The following `errno' error - conditions are defined for this function: - - `EPROTONOSUPPORT' - The PROTOCOL or STYLE is not supported by the NAMESPACE - specified. - - `EMFILE' - The process already has too many file descriptors open. - - `ENFILE' - The system already has too many file descriptors open. - - `EACCES' - The process does not have the privilege to create a socket of - the specified STYLE or PROTOCOL. - - `ENOBUFS' - The system ran out of internal buffer space. - - The file descriptor returned by the `socket' function supports both - read and write operations. However, like pipes, sockets do not - support file positioning operations. - - For examples of how to call the `socket' function, see *Note Local -Socket Example::, or *Note Inet Example::. - - -File: libc.info, Node: Closing a Socket, Next: Socket Pairs, Prev: Creating a Socket, Up: Open/Close Sockets - -Closing a Socket ----------------- - - When you have finished using a socket, you can simply close its file -descriptor with `close'; see *Note Opening and Closing Files::. If -there is still data waiting to be transmitted over the connection, -normally `close' tries to complete this transmission. You can control -this behavior using the `SO_LINGER' socket option to specify a timeout -period; see *Note Socket Options::. - - You can also shut down only reception or transmission on a -connection by calling `shutdown', which is declared in `sys/socket.h'. - - - Function: int shutdown (int SOCKET, int HOW) - The `shutdown' function shuts down the connection of socket - SOCKET. The argument HOW specifies what action to perform: - - `0' - Stop receiving data for this socket. If further data arrives, - reject it. - - `1' - Stop trying to transmit data from this socket. Discard any - data waiting to be sent. Stop looking for acknowledgement of - data already sent; don't retransmit it if it is lost. - - `2' - Stop both reception and transmission. - - The return value is `0' on success and `-1' on failure.

When the queue fills, new clients attempting to - connect fail with `ECONNREFUSED' until the server calls `accept' to - accept a connection from the queue. - - The `listen' function returns `0' on success and `-1' on failure. - The following `errno' error conditions are defined for this - function: - - `EBADF' - The argument SOCKET is not a valid file descriptor. - - `ENOTSOCK' - The argument SOCKET is not a socket. - - `EOPNOTSUPP' - The socket SOCKET does not support this operation. - - -File: libc.info, Node: Accepting Connections, Next: Who is Connected, Prev: Listening, Up: Connections - -Accepting Connections ---------------------- - - When a server receives a connection request, it can complete the -connection by accepting the request. Use the function `accept' to do -this. - - A socket that has been established as a server can accept connection -requests from multiple clients. The server's original socket _does not -become part of the connection_; instead, `accept' makes a new socket -which participates in the connection. `accept' returns the descriptor -for this socket.

When it receives a message, it accepts the -connection (if the socket style calls for connections) and then forks a -child process to run the corresponding server program. You specify the -ports and their programs in the file `/etc/inetd.conf'. - -* Menu: - -* Inetd Servers:: -* Configuring Inetd:: - - -File: libc.info, Node: Inetd Servers, Next: Configuring Inetd, Up: Inetd - -`inetd' Servers ---------------- - - Writing a server program to be run by `inetd' is very simple. Each -time someone requests a connection to the appropriate port, a new server -process starts. The connection already exists at this time; the socket -is available as the standard input descriptor and as the standard -output descriptor (descriptors 0 and 1) in the server process. Thus -the server program can begin reading and writing data right away. -Often the program needs only the ordinary I/O facilities; in fact, a -general-purpose filter program that knows nothing about sockets can -work as a byte stream server run by `inetd'. - - You can also use `inetd' for servers that use connectionless -communication styles. For these servers, `inetd' does not try to accept -a connection since no connection is possible. It just starts the -server program, which can read the incoming datagram packet from -descriptor 0. The server program can handle one request and then exit, -or you can choose to write it to keep reading more requests until no -more arrive, and then exit. You must specify which of these two -techniques the server uses when you configure `inetd'. - - -File: libc.info, Node: Configuring Inetd, Prev: Inetd Servers, Up: Inetd - -Configuring `inetd' -------------------- - - The file `/etc/inetd.conf' tells `inetd' which ports to listen to -and what server programs to run for them. Normally each entry in the -file is one line, but you can split it onto multiple lines provided all -but the first line of the entry start with whitespace. Lines that -start with `#' are comments. - - Here are two standard entries in `/etc/inetd.conf': - - ftp stream tcp nowait root /libexec/ftpd ftpd - talk dgram udp wait root /libexec/talkd talkd - - An entry has this format: - - SERVICE STYLE PROTOCOL WAIT USERNAME PROGRAM ARGUMENTS - - The SERVICE field says which service this program provides. It -should be the name of a service defined in `/etc/services'. `inetd' -uses SERVICE to decide which port to listen on for this entry. - - The fields STYLE and PROTOCOL specify the communication style and -the protocol to use for the listening socket. The style should be the -name of a communication style, converted to lower case and with `SOCK_' -deleted--for example, `stream' or `dgram'. PROTOCOL should be one of -the protocols listed in `/etc/protocols'. The typical protocol names -are `tcp' for byte stream connections and `udp' for unreliable -datagrams. - - The WAIT field should be either `wait' or `nowait'. Use `wait' if -STYLE is a connectionless style and the server, once started, handles -multiple requests as they come in. Use `nowait' if `inetd' should -start a new process for each message or request that comes in. If -STYLE uses connections, then WAIT *must* be `nowait'. - - USER is the user name that the server should run as. `inetd' runs -as root, so it can set the user ID of its children arbitrarily. It's -best to avoid using `root' for USER if you can; but some servers, such -as Telnet and FTP, read a username and password themselves. These -servers need to be root initially so they can log in as commanded by -the data coming over the network. - - PROGRAM together with ARGUMENTS specifies the command to run to -start the server. PROGRAM should be an absolute file name specifying -the executable file to run. ARGUMENTS consists of any number of -whitespace-separated words, which become the command-line arguments of -PROGRAM. The first word in ARGUMENTS is argument zero, which should by -convention be the program name itself (sans directories). - - If you edit `/etc/inetd.conf', you can tell `inetd' to reread the -file and obey its new contents by sending the `inetd' process the -`SIGHUP' signal. You'll have to use `ps' to determine the process ID -of the `inetd' process as it is not fixed. - - -File: libc.info, Node: Socket Options, Next: Networks Database, Prev: Inetd, Up: Sockets - -Socket Options -============== - - This section describes how to read or set various options that modify -the behavior of sockets and their underlying communications protocols. - - When you are manipulating a socket option, you must specify which -"level" the option pertains to.

See also the -`ctermid' function, described in *Note Identifying the Terminal::. - - - Function: char * ttyname (int FILEDES) - If the file descriptor FILEDES is associated with a terminal - device, the `ttyname' function returns a pointer to a - statically-allocated, null-terminated string containing the file - name of the terminal file.

Otherwise an error - number is returned to indicate the error. The following `errno' - error conditions are defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `ENOTTY' - The FILEDES is not associated with a terminal. - - `ERANGE' - The buffer length LEN is too small to store the string to be - returned. - - -File: libc.info, Node: I/O Queues, Next: Canonical or Not, Prev: Is It a Terminal, Up: Low-Level Terminal Interface - -I/O Queues -========== - - Many of the remaining functions in this section refer to the input -and output queues of a terminal device. These queues implement a form -of buffering _within the kernel_ independent of the buffering -implemented by I/O streams (*note I/O on Streams::). - - The "terminal input queue" is also sometimes referred to as its -"typeahead buffer". It holds the characters that have been received -from the terminal but not yet read by any process. - - The size of the input queue is described by the `MAX_INPUT' and -`_POSIX_MAX_INPUT' parameters; see *Note Limits for Files::. You are -guaranteed a queue size of at least `MAX_INPUT', but the queue might be -larger, and might even dynamically change size. If input flow control -is enabled by setting the `IXOFF' input mode bit (*note Input Modes::), -the terminal driver transmits STOP and START characters to the terminal -when necessary to prevent the queue from overflowing. Otherwise, input -may be lost if it comes in too fast from the terminal. In canonical -mode, all input stays in the queue until a newline character is -received, so the terminal input queue can fill up when you type a very -long line. *Note Canonical or Not::. - - The "terminal output queue" is like the input queue, but for output; -it contains characters that have been written by processes, but not yet -transmitted to the terminal. If output flow control is enabled by -setting the `IXON' input mode bit (*note Input Modes::), the terminal -driver obeys START and STOP characters sent by the terminal to stop and -restart transmission of output. - - "Clearing" the terminal input queue means discarding any characters -that have been received but not yet read.

No input -can be read until an entire line has been typed by the user, and the -`read' function (*note I/O Primitives::) returns at most a single line -of input, no matter how many bytes are requested. - - In canonical input mode, the operating system provides input editing -facilities: some characters are interpreted specially to perform editing -operations within the current line of text, such as ERASE and KILL. -*Note Editing Characters::. - - The constants `_POSIX_MAX_CANON' and `MAX_CANON' parameterize the -maximum number of bytes which may appear in a single line of canonical -input. *Note Limits for Files::. You are guaranteed a maximum line -length of at least `MAX_CANON' bytes, but the maximum might be larger, -and might even dynamically change size. - - In "noncanonical input processing" mode, characters are not grouped -into lines, and ERASE and KILL processing is not performed. The -granularity with which bytes are read in noncanonical input mode is -controlled by the MIN and TIME settings. *Note Noncanonical Input::. - - Most programs use canonical input mode, because this gives the user a -way to edit input line by line. The usual reason to use noncanonical -mode is when the program accepts single-character commands or provides -its own editing facilities. - - The choice of canonical or noncanonical input is controlled by the -`ICANON' flag in the `c_lflag' member of `struct termios'. *Note Local -Modes::. - - -File: libc.info, Node: Terminal Modes, Next: BSD Terminal Modes, Prev: Canonical or Not, Up: Low-Level Terminal Interface - -Terminal Modes -============== - - This section describes the various terminal attributes that control -how input and output are done.

The attributes are returned - in the structure that TERMIOS-P points to. - - If successful, `tcgetattr' returns 0. A return value of -1 - indicates an error. The following `errno' error conditions are - defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `ENOTTY' - The FILEDES is not associated with a terminal. - - - Function: int tcsetattr (int FILEDES, int WHEN, const struct termios - *TERMIOS-P) - This function sets the attributes of the terminal device with file - descriptor FILEDES. The new attributes are taken from the - structure that TERMIOS-P points to. - - The WHEN argument specifies how to deal with input and output - already queued. It can be one of the following values: - - `TCSANOW' - Make the change immediately. - - `TCSADRAIN' - Make the change after waiting until all queued output has - been written. You should usually use this option when - changing parameters that affect output. - - `TCSAFLUSH' - This is like `TCSADRAIN', but also discards any queued input. - - `TCSASOFT' - This is a flag bit that you can add to any of the above - alternatives. Its meaning is to inhibit alteration of the - state of the terminal hardware. It is a BSD extension; it is - only supported on BSD systems and the GNU system. - - Using `TCSASOFT' is exactly the same as setting the `CIGNORE' - bit in the `c_cflag' member of the structure TERMIOS-P points - to. *Note Control Modes::, for a description of `CIGNORE'. - - If this function is called from a background process on its - controlling terminal, normally all processes in the process group - are sent a `SIGTTOU' signal, in the same way as if the process - were trying to write to the terminal. The exception is if the - calling process itself is ignoring or blocking `SIGTTOU' signals, - in which case the operation is performed and no signal is sent. - *Note Job Control::. - - If successful, `tcsetattr' returns 0. A return value of -1 - indicates an error. The following `errno' error conditions are - defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `ENOTTY' - The FILEDES is not associated with a terminal. - - `EINVAL' - Either the value of the `when' argument is not valid, or - there is something wrong with the data in the TERMIOS-P - argument. - - Although `tcgetattr' and `tcsetattr' specify the terminal device -with a file descriptor, the attributes are those of the terminal device -itself and not of the file descriptor. This means that the effects of -changing terminal attributes are persistent; if another process opens -the terminal file later on, it will see the changed attributes even -though it doesn't have anything to do with the open file descriptor you -originally specified in changing the attributes. - - Similarly, if a single process has multiple or duplicated file -descriptors for the same terminal device, changing the terminal -attributes affects input and output to all of these file descriptors. -This means, for example, that you can't open one file descriptor or -stream to read from a terminal in the normal line-buffered, echoed -mode; and simultaneously have another file descriptor for the same -terminal that you use to read from it in single-character, non-echoed -mode. Instead, you have to explicitly switch the terminal back and -forth between the two modes. - - -File: libc.info, Node: Setting Modes, Next: Input Modes, Prev: Mode Functions, Up: Terminal Modes - -Setting Terminal Modes Properly -------------------------------- - - When you set terminal modes, you should call `tcgetattr' first to -get the current modes of the particular terminal device, modify only -those modes that you are really interested in, and store the result with -`tcsetattr'. - - It's a bad idea to simply initialize a `struct termios' structure to -a chosen set of attributes and pass it directly to `tcsetattr'. Your -program may be run years from now, on systems that support members not -documented in this manual. The way to avoid setting these members to -unreasonable values is to avoid changing them. - - What's more, different terminal devices may require different mode -settings in order to function properly. So you should avoid blindly -copying attributes from one terminal device to another. - - When a member contains a collection of independent flags, as the -`c_iflag', `c_oflag' and `c_cflag' members do, even setting the entire -member is a bad idea, because particular operating systems have their -own flags. Instead, you should start with the current value of the -member and alter only the flags whose values matter in your program, -leaving any other flags unchanged. - - Here is an example of how to set one flag (`ISTRIP') in the `struct -termios' structure while properly preserving all the other data in the -structure: - - int - set_istrip (int desc, int value) - { - struct termios settings; - int result; - - result = tcgetattr (desc, &settings); - if (result < 0) - { - perror ("error in tcgetattr"); - return 0; - } - settings.c_iflag &= ~ISTRIP; - if (value) - settings.c_iflag |= ISTRIP; - result = tcsetattr (desc, TCSANOW, &settings); - if (result < 0) - { - perror ("error in tcsetattr"); - return 0; - } - return 1; - } - - -File: libc.info, Node: Input Modes, Next: Output Modes, Prev: Setting Modes, Up: Terminal Modes - -Input Modes ------------ - - This section describes the terminal attribute flags that control -fairly low-level aspects of input processing: handling of parity errors, -break signals, flow control, and and characters. - - All of these flags are bits in the `c_iflag' member of the `struct -termios' structure. The member is an integer, and you change flags -using the operators `&', `|' and `^'. Don't try to specify the entire -value for `c_iflag'--instead, change only specific flags and leave the -rest untouched (*note Setting Modes::). - - - Macro: tcflag_t INPCK - If this bit is set, input parity checking is enabled. If it is - not set, no checking at all is done for parity errors on input; the - characters are simply passed through to the application. - - Parity checking on input processing is independent of whether - parity detection and generation on the underlying terminal - hardware is enabled; see *Note Control Modes::. For example, you - could clear the `INPCK' input mode flag and set the `PARENB' - control mode flag to ignore parity errors on input, but still - generate parity on output. - - If this bit is set, what happens when a parity error is detected - depends on whether the `IGNPAR' or `PARMRK' bits are set. If - neither of these bits are set, a byte with a parity error is - passed to the application as a `'\0'' character. - - - Macro: tcflag_t IGNPAR - If this bit is set, any byte with a framing or parity error is - ignored. This is only useful if `INPCK' is also set. - - - Macro: tcflag_t PARMRK - If this bit is set, input bytes with parity or framing errors are - marked when passed to the program. This bit is meaningful only - when `INPCK' is set and `IGNPAR' is not set. - - The way erroneous bytes are marked is with two preceding bytes, - `377' and `0'. Thus, the program actually reads three bytes for - one erroneous byte received from the terminal. - - If a valid byte has the value `0377', and `ISTRIP' (see below) is - not set, the program might confuse it with the prefix that marks a - parity error. So a valid byte `0377' is passed to the program as - two bytes, `0377' `0377', in this case. - - - Macro: tcflag_t ISTRIP - If this bit is set, valid input bytes are stripped to seven bits; - otherwise, all eight bits are available for programs to read. - - - Macro: tcflag_t IGNBRK - If this bit is set, break conditions are ignored. - - A "break condition" is defined in the context of asynchronous - serial data transmission as a series of zero-value bits longer - than a single byte. - - - Macro: tcflag_t BRKINT - If this bit is set and `IGNBRK' is not set, a break condition - clears the terminal input and output queues and raises a `SIGINT' - signal for the foreground process group associated with the - terminal. - - If neither `BRKINT' nor `IGNBRK' are set, a break condition is - passed to the application as a single `'\0'' character if `PARMRK' - is not set, or otherwise as a three-character sequence `'\377'', - `'\0'', `'\0''. - - - Macro: tcflag_t IGNCR - If this bit is set, carriage return characters (`'\r'') are - discarded on input. Discarding carriage return may be useful on - terminals that send both carriage return and linefeed when you - type the key. - - - Macro: tcflag_t ICRNL - If this bit is set and `IGNCR' is not set, carriage return - characters (`'\r'') received as input are passed to the - application as newline characters (`'\n''). - - - Macro: tcflag_t INLCR - If this bit is set, newline characters (`'\n'') received as input - are passed to the application as carriage return characters - (`'\r''). - - - Macro: tcflag_t IXOFF - If this bit is set, start/stop control on input is enabled. In - other words, the computer sends STOP and START characters as - necessary to prevent input from coming in faster than programs are - reading it. The idea is that the actual terminal hardware that is - generating the input data responds to a STOP character by - suspending transmission, and to a START character by resuming - transmission. *Note Start/Stop Characters::. - - - Macro: tcflag_t IXON - If this bit is set, start/stop control on output is enabled. In - other words, if the computer receives a STOP character, it - suspends output until a START character is received. In this - case, the STOP and START characters are never passed to the - application program. If this bit is not set, then START and STOP - can be read as ordinary characters. *Note Start/Stop Characters::. - - - Macro: tcflag_t IXANY - If this bit is set, any input character restarts output when - output has been suspended with the STOP character. Otherwise, - only the START character restarts output. - - This is a BSD extension; it exists only on BSD systems and the GNU - system. - - - Macro: tcflag_t IMAXBEL - If this bit is set, then filling up the terminal input buffer - sends a BEL character (code `007') to the terminal to ring the - bell. - - This is a BSD extension. - - -File: libc.info, Node: Output Modes, Next: Control Modes, Prev: Input Modes, Up: Terminal Modes - -Output Modes ------------- - - This section describes the terminal flags and fields that control how -output characters are translated and padded for display.

Don't try to specify -the entire value for `c_oflag'--instead, change only specific flags and -leave the rest untouched (*note Setting Modes::). - - - Macro: tcflag_t OPOST - If this bit is set, output data is processed in some unspecified - way so that it is displayed appropriately on the terminal device. - This typically includes mapping newline characters (`'\n'') onto - carriage return and linefeed pairs. - - If this bit isn't set, the characters are transmitted as-is. - - The following three bits are BSD features, and they exist only BSD -systems and the GNU system. They are effective only if `OPOST' is set. - - - Macro: tcflag_t ONLCR - If this bit is set, convert the newline character on output into a - pair of characters, carriage return followed by linefeed. - - - Macro: tcflag_t OXTABS - If this bit is set, convert tab characters on output into the - appropriate number of spaces to emulate a tab stop every eight - columns. - - - Macro: tcflag_t ONOEOT - If this bit is set, discard `C-d' characters (code `004') on - output.

These flags may not make sense for other kinds of -terminal ports (such as a network connection pseudo-terminal). All of -these are contained in the `c_cflag' member of the `struct termios' -structure. - - The `c_cflag' member itself is an integer, and you change the flags -and fields using the operators `&', `|', and `^'. Don't try to specify -the entire value for `c_cflag'--instead, change only specific flags and -leave the rest untouched (*note Setting Modes::). - - - Macro: tcflag_t CLOCAL - If this bit is set, it indicates that the terminal is connected - "locally" and that the modem status lines (such as carrier detect) - should be ignored. - - On many systems if this bit is not set and you call `open' without - the `O_NONBLOCK' flag set, `open' blocks until a modem connection - is established. - - If this bit is not set and a modem disconnect is detected, a - `SIGHUP' signal is sent to the controlling process group for the - terminal (if it has one). Normally, this causes the process to - exit; see *Note Signal Handling::. Reading from the terminal - after a disconnect causes an end-of-file condition, and writing - causes an `EIO' error to be returned. The terminal device must be - closed and reopened to clear the condition. - - - Macro: tcflag_t HUPCL - If this bit is set, a modem disconnect is generated when all - processes that have the terminal device open have either closed - the file or exited. - - - Macro: tcflag_t CREAD - If this bit is set, input can be read from the terminal. - Otherwise, input is discarded when it arrives. - - - Macro: tcflag_t CSTOPB - If this bit is set, two stop bits are used. Otherwise, only one - stop bit is used. - - - Macro: tcflag_t PARENB - If this bit is set, generation and detection of a parity bit are - enabled. *Note Input Modes::, for information on how input parity - errors are handled. - - If this bit is not set, no parity bit is added to output - characters, and input characters are not checked for correct - parity. - - - Macro: tcflag_t PARODD - This bit is only useful if `PARENB' is set. If `PARODD' is set, - odd parity is used, otherwise even parity is used. - - The control mode flags also includes a field for the number of bits -per character. You can use the `CSIZE' macro as a mask to extract the -value, like this: `settings.c_cflag & CSIZE'. - - - Macro: tcflag_t CSIZE - This is a mask for the number of bits per character. - - - Macro: tcflag_t CS5 - This specifies five bits per byte. - - - Macro: tcflag_t CS6 - This specifies six bits per byte. - - - Macro: tcflag_t CS7 - This specifies seven bits per byte. - - - Macro: tcflag_t CS8 - This specifies eight bits per byte. - - The following four bits are BSD extensions; this exist only on BSD -systems and the GNU system. - - - Macro: tcflag_t CCTS_OFLOW - If this bit is set, enable flow control of output based on the CTS - wire (RS232 protocol). - - - Macro: tcflag_t CRTS_IFLOW - If this bit is set, enable flow control of input based on the RTS - wire (RS232 protocol). - - - Macro: tcflag_t MDMBUF - If this bit is set, enable carrier-based flow control of output. - - - Macro: tcflag_t CIGNORE - If this bit is set, it says to ignore the control modes and line - speed values entirely. This is only meaningful in a call to - `tcsetattr'. - - The `c_cflag' member and the line speed values returned by - `cfgetispeed' and `cfgetospeed' will be unaffected by the call. - `CIGNORE' is useful if you want to set all the software modes in - the other members, but leave the hardware details in `c_cflag' - unchanged. (This is how the `TCSASOFT' flag to `tcsettattr' - works.) - - This bit is never set in the structure filled in by `tcgetattr'. - - -File: libc.info, Node: Local Modes, Next: Line Speed, Prev: Control Modes, Up: Terminal Modes - -Local Modes ------------ - - This section describes the flags for the `c_lflag' member of the -`struct termios' structure. These flags generally control higher-level -aspects of input processing than the input modes flags described in -*Note Input Modes::, such as echoing, signals, and the choice of -canonical or noncanonical input. - - The `c_lflag' member itself is an integer, and you change the flags -and fields using the operators `&', `|', and `^'. Don't try to specify -the entire value for `c_lflag'--instead, change only specific flags and -leave the rest untouched (*note Setting Modes::). - - - Macro: tcflag_t ICANON - This bit, if set, enables canonical input processing mode. - Otherwise, input is processed in noncanonical mode. *Note - Canonical or Not::. - - - Macro: tcflag_t ECHO - If this bit is set, echoing of input characters back to the - terminal is enabled. - - - Macro: tcflag_t ECHOE - If this bit is set, echoing indicates erasure of input with the - ERASE character by erasing the last character in the current line - from the screen. Otherwise, the character erased is re-echoed to - show what has happened (suitable for a printing terminal). - - This bit only controls the display behavior; the `ICANON' bit by - itself controls actual recognition of the ERASE character and - erasure of input, without which `ECHOE' is simply irrelevant. - - - Macro: tcflag_t ECHOPRT - This bit is like `ECHOE', enables display of the ERASE character in - a way that is geared to a hardcopy terminal. When you type the - ERASE character, a `\' character is printed followed by the first - character erased. Typing the ERASE character again just prints - the next character erased. Then, the next time you type a normal - character, a `/' character is printed before the character echoes. - - This is a BSD extension, and exists only in BSD systems and the - GNU system. - - - Macro: tcflag_t ECHOK - This bit enables special display of the KILL character by moving - to a new line after echoing the KILL character normally. The - behavior of `ECHOKE' (below) is nicer to look at. - - If this bit is not set, the KILL character echoes just as it would - if it were not the KILL character. Then it is up to the user to - remember that the KILL character has erased the preceding input; - there is no indication of this on the screen. - - This bit only controls the display behavior; the `ICANON' bit by - itself controls actual recognition of the KILL character and - erasure of input, without which `ECHOK' is simply irrelevant. - - - Macro: tcflag_t ECHOKE - This bit is similar to `ECHOK'. It enables special display of the - KILL character by erasing on the screen the entire line that has - been killed. This is a BSD extension, and exists only in BSD - systems and the GNU system. - - - Macro: tcflag_t ECHONL - If this bit is set and the `ICANON' bit is also set, then the - newline (`'\n'') character is echoed even if the `ECHO' bit is not - set. - - - Macro: tcflag_t ECHOCTL - If this bit is set and the `ECHO' bit is also set, echo control - characters with `^' followed by the corresponding text character. - Thus, control-A echoes as `^A'. This is usually the preferred mode - for interactive input, because echoing a control character back to - the terminal could have some undesired effect on the terminal. - - This is a BSD extension, and exists only in BSD systems and the - GNU system. - - - Macro: tcflag_t ISIG - This bit controls whether the INTR, QUIT, and SUSP characters are - recognized. The functions associated with these characters are - performed if and only if this bit is set. Being in canonical or - noncanonical input mode has no affect on the interpretation of - these characters. - - You should use caution when disabling recognition of these - characters. Programs that cannot be interrupted interactively are - very user-unfriendly. If you clear this bit, your program should - provide some alternate interface that allows the user to - interactively send the signals associated with these characters, - or to escape from the program. - - *Note Signal Characters::. - - - Macro: tcflag_t IEXTEN - POSIX.1 gives `IEXTEN' implementation-defined meaning, so you - cannot rely on this interpretation on all systems. - - On BSD systems and the GNU system, it enables the LNEXT and - DISCARD characters. *Note Other Special::. - - - Macro: tcflag_t NOFLSH - Normally, the INTR, QUIT, and SUSP characters cause input and - output queues for the terminal to be cleared. If this bit is set, - the queues are not cleared. - - - Macro: tcflag_t TOSTOP - If this bit is set and the system supports job control, then - `SIGTTOU' signals are generated by background processes that - attempt to write to the terminal. *Note Access to the Terminal::. - - The following bits are BSD extensions; they exist only in BSD systems -and the GNU system. - - - Macro: tcflag_t ALTWERASE - This bit determines how far the WERASE character should erase. The - WERASE character erases back to the beginning of a word; the - question is, where do words begin? - - If this bit is clear, then the beginning of a word is a - nonwhitespace character following a whitespace character. If the - bit is set, then the beginning of a word is an alphanumeric - character or underscore following a character which is none of - those. - - *Note Editing Characters::, for more information about the WERASE - character. - - - Macro: tcflag_t FLUSHO - This is the bit that toggles when the user types the DISCARD - character. While this bit is set, all output is discarded. *Note - Other Special::. - - - Macro: tcflag_t NOKERNINFO - Setting this bit disables handling of the STATUS character. *Note - Other Special::. - - - Macro: tcflag_t PENDIN - If this bit is set, it indicates that there is a line of input that - needs to be reprinted. Typing the REPRINT character sets this - bit; the bit remains set until reprinting is finished. *Note - Editing Characters::. - - -File: libc.info, Node: Line Speed, Next: Special Characters, Prev: Local Modes, Up: Terminal Modes - -Line Speed ----------- - - The terminal line speed tells the computer how fast to read and write -data on the terminal. - - If the terminal is connected to a real serial line, the terminal -speed you specify actually controls the line--if it doesn't match the -terminal's own idea of the speed, communication does not work. Real -serial ports accept only certain standard speeds. Also, particular -hardware may not support even all the standard speeds. Specifying a -speed of zero hangs up a dialup connection and turns off modem control -signals. - - If the terminal is not a real serial line (for example, if it is a -network connection), then the line speed won't really affect data -transmission speed, but some programs will use it to determine the -amount of padding needed. It's best to specify a line speed value that -matches the actual speed of the actual terminal, but you can safely -experiment with different values to vary the amount of padding. - - There are actually two line speeds for each terminal, one for input -and one for output. You can set them independently, but most often -terminals use the same speed for both directions. - - The speed values are stored in the `struct termios' structure, but -don't try to access them in the `struct termios' structure directly. -Instead, you should use the following functions to read and store them: - - - Function: speed_t cfgetospeed (const struct termios *TERMIOS-P) - This function returns the output line speed stored in the structure - `*TERMIOS-P'. - - - Function: speed_t cfgetispeed (const struct termios *TERMIOS-P) - This function returns the input line speed stored in the structure - `*TERMIOS-P'. - - - Function: int cfsetospeed (struct termios *TERMIOS-P, speed_t SPEED) - This function stores SPEED in `*TERMIOS-P' as the output speed. - The normal return value is 0; a value of -1 indicates an error. - If SPEED is not a speed, `cfsetospeed' returns -1. - - - Function: int cfsetispeed (struct termios *TERMIOS-P, speed_t SPEED) - This function stores SPEED in `*TERMIOS-P' as the input speed. - The normal return value is 0; a value of -1 indicates an error. - If SPEED is not a speed, `cfsetospeed' returns -1. - - - Function: int cfsetspeed (struct termios *TERMIOS-P, speed_t SPEED) - This function stores SPEED in `*TERMIOS-P' as both the input and - output speeds. The normal return value is 0; a value of -1 - indicates an error. If SPEED is not a speed, `cfsetspeed' returns - -1. This function is an extension in 4.4 BSD. - - - Data Type: speed_t - The `speed_t' type is an unsigned integer data type used to - represent line speeds. - - The functions `cfsetospeed' and `cfsetispeed' report errors only for -speed values that the system simply cannot handle. If you specify a -speed value that is basically acceptable, then those functions will -succeed. But they do not check that a particular hardware device can -actually support the specified speeds--in fact, they don't know which -device you plan to set the speed for. If you use `tcsetattr' to set -the speed of a particular device to a value that it cannot handle, -`tcsetattr' returns -1. - - *Portability note:* In the GNU library, the functions above accept -speeds measured in bits per second as input, and return speed values -measured in bits per second. Other libraries require speeds to be -indicated by special codes. For POSIX.1 portability, you must use one -of the following symbols to represent the speed; their precise numeric -values are system-dependent, but each name has a fixed meaning: `B110' -stands for 110 bps, `B300' for 300 bps, and so on. There is no -portable way to represent any speed but these, but these are the only -speeds that typical serial lines can support. - - B0 B50 B75 B110 B134 B150 B200 - B300 B600 B1200 B1800 B2400 B4800 - B9600 B19200 B38400 B57600 B115200 - B230400 B460800 - - BSD defines two additional speed symbols as aliases: `EXTA' is an -alias for `B19200' and `EXTB' is an alias for `B38400'. These aliases -are obsolete. - - -File: libc.info, Node: Special Characters, Next: Noncanonical Input, Prev: Line Speed, Up: Terminal Modes - -Special Characters ------------------- - - In canonical input, the terminal driver recognizes a number of -special characters which perform various control functions. These -include the ERASE character (usually ) for editing input, and -other editing characters. The INTR character (normally `C-c') for -sending a `SIGINT' signal, and other signal-raising characters, may be -available in either canonical or noncanonical input mode. All these -characters are described in this section. - - The particular characters used are specified in the `c_cc' member of -the `struct termios' structure. This member is an array; each element -specifies the character for a particular role. Each element has a -symbolic constant that stands for the index of that element--for -example, `VINTR' is the index of the element that specifies the INTR -character, so storing `'='' in `TERMIOS.c_cc[VINTR]' specifies `=' as -the INTR character. - - On some systems, you can disable a particular special character -function by specifying the value `_POSIX_VDISABLE' for that role.

If you get this - error, you might want to increase the `RLIMIT_NOFILE' limit or - make it unlimited; *note Limits on Resources::. - - - Macro: int ENFILE - There are too many distinct file openings in the entire system. - Note that any number of linked channels count as just one file - opening; see *Note Linked Channels::. This error never occurs in - the GNU system. - - - Macro: int ENOTTY - Inappropriate I/O control operation, such as trying to set terminal - modes on an ordinary file. - - - Macro: int ETXTBSY - An attempt to execute a file that is currently open for writing, or - write to a file that is currently being executed. Often using a - debugger to run a program is considered having it open for writing - and will cause this error. (The name stands for "text file - busy".) This is not an error in the GNU system; the text is - copied as necessary. - - - Macro: int EFBIG - File too big; the size of a file would be larger than allowed by - the system. - - - Macro: int ENOSPC - No space left on device; write operation on a file failed because - the disk is full. - - - Macro: int ESPIPE - Invalid seek operation (such as on a pipe). - - - Macro: int EROFS - An attempt was made to modify something on a read-only file system. - - - Macro: int EMLINK - Too many links; the link count of a single file would become too - large. `rename' can cause this error if the file being renamed - already has as many links as it can take (*note Renaming Files::). - - - Macro: int EPIPE - Broken pipe; there is no process reading from the other end of a - pipe. Every library function that returns this error code also - generates a `SIGPIPE' signal; this signal terminates the program - if not handled or blocked. Thus, your program will never actually - see `EPIPE' unless it has handled or blocked `SIGPIPE'. - - - Macro: int EDOM - Domain error; used by mathematical functions when an argument - value does not fall into the domain over which the function is - defined. - - - Macro: int ERANGE - Range error; used by mathematical functions when the result value - is not representable because of overflow or underflow. - - - Macro: int EAGAIN - Resource temporarily unavailable; the call might work if you try - again later. The macro `EWOULDBLOCK' is another name for `EAGAIN'; - they are always the same in the GNU C library. - - This error can happen in a few different situations: - - * An operation that would block was attempted on an object that - has non-blocking mode selected. Trying the same operation - again will block until some external condition makes it - possible to read, write, or connect (whatever the operation). - You can use `select' to find out when the operation will be - possible; *note Waiting for I/O::. - - *Portability Note:* In many older Unix systems, this condition - was indicated by `EWOULDBLOCK', which was a distinct error - code different from `EAGAIN'. To make your program portable, - you should check for both codes and treat them the same. - - * A temporary resource shortage made an operation impossible. - `fork' can return this error. It indicates that the shortage - is expected to pass, so your program can try the call again - later and it may succeed. It is probably a good idea to - delay for a few seconds before trying it again, to allow time - for other processes to release scarce resources. Such - shortages are usually fairly serious and affect the whole - system, so usually an interactive program should report the - error to the user and return to its command loop. - - - Macro: int EWOULDBLOCK - In the GNU C library, this is another name for `EAGAIN' (above). - The values are always the same, on every operating system. - - C libraries in many older Unix systems have `EWOULDBLOCK' as a - separate error code. - - - Macro: int EINPROGRESS - An operation that cannot complete immediately was initiated on an - object that has non-blocking mode selected. Some functions that - must always block (such as `connect'; *note Connecting::) never - return `EAGAIN'. Instead, they return `EINPROGRESS' to indicate - that the operation has begun and will take some time. Attempts to - manipulate the object before the call completes return `EALREADY'. - You can use the `select' function to find out when the pending - operation has completed; *note Waiting for I/O::. - - - Macro: int EALREADY - An operation is already in progress on an object that has - non-blocking mode selected. - - - Macro: int ENOTSOCK - A file that isn't a socket was specified when a socket is required. - - - Macro: int EMSGSIZE - The size of a message sent on a socket was larger than the - supported maximum size. - - - Macro: int EPROTOTYPE - The socket type does not support the requested communications - protocol. - - - Macro: int ENOPROTOOPT - You specified a socket option that doesn't make sense for the - particular protocol being used by the socket. *Note Socket - Options::. - - - Macro: int EPROTONOSUPPORT - The socket domain does not support the requested communications - protocol (perhaps because the requested protocol is completely - invalid). *Note Creating a Socket::. - - - Macro: int ESOCKTNOSUPPORT - The socket type is not supported. - - - Macro: int EOPNOTSUPP - The operation you requested is not supported. Some socket - functions don't make sense for all types of sockets, and others - may not be implemented for all communications protocols. In the - GNU system, this error can happen for many calls when the object - does not support the particular operation; it is a generic - indication that the server knows nothing to do for that call. - - - Macro: int EPFNOSUPPORT - The socket communications protocol family you requested is not - supported. - - - Macro: int EAFNOSUPPORT - The address family specified for a socket is not supported; it is - inconsistent with the protocol being used on the socket. *Note - Sockets::. - - - Macro: int EADDRINUSE - The requested socket address is already in use. *Note Socket - Addresses::. - - - Macro: int EADDRNOTAVAIL - The requested socket address is not available; for example, you - tried to give a socket a name that doesn't match the local host - name. *Note Socket Addresses::. - - - Macro: int ENETDOWN - A socket operation failed because the network was down. - - - Macro: int ENETUNREACH - A socket operation failed because the subnet containing the remote - host was unreachable. - - - Macro: int ENETRESET - A network connection was reset because the remote host crashed. - - - Macro: int ECONNABORTED - A network connection was aborted locally. - - - Macro: int ECONNRESET - A network connection was closed for reasons outside the control of - the local host, such as by the remote machine rebooting or an - unrecoverable protocol violation. - - - Macro: int ENOBUFS - The kernel's buffers for I/O operations are all in use. In GNU, - this error is always synonymous with `ENOMEM'; you may get one or - the other from network operations. - - - Macro: int EISCONN - You tried to connect a socket that is already connected. *Note - Connecting::. - - - Macro: int ENOTCONN - The socket is not connected to anything. You get this error when - you try to transmit data over a socket, without first specifying a - destination for the data. For a connectionless socket (for - datagram protocols, such as UDP), you get `EDESTADDRREQ' instead. - - - Macro: int EDESTADDRREQ - No default destination address was set for the socket. You get - this error when you try to transmit data over a connectionless - socket, without first specifying a destination for the data with - `connect'. - - - Macro: int ESHUTDOWN - The socket has already been shut down. - - - Macro: int ETOOMANYREFS - ??? - - - Macro: int ETIMEDOUT - A socket operation with a specified timeout received no response - during the timeout period. - - - Macro: int ECONNREFUSED - A remote host refused to allow the network connection (typically - because it is not running the requested service). - - - Macro: int ELOOP - Too many levels of symbolic links were encountered in looking up a - file name. This often indicates a cycle of symbolic links. - - - Macro: int ENAMETOOLONG - Filename too long (longer than `PATH_MAX'; *note Limits for - Files::) or host name too long (in `gethostname' or `sethostname'; - *note Host Identification::). - - - Macro: int EHOSTDOWN - The remote host for a requested network connection is down. - - - Macro: int EHOSTUNREACH - The remote host for a requested network connection is not - reachable. - - - Macro: int ENOTEMPTY - Directory not empty, where an empty directory was expected. - Typically, this error occurs when you are trying to delete a - directory. - - - Macro: int EPROCLIM - This means that the per-user limit on new process would be - exceeded by an attempted `fork'. *Note Limits on Resources::, for - details on the `RLIMIT_NPROC' limit. - - - Macro: int EUSERS - The file quota system is confused because there are too many users. - - - Macro: int EDQUOT - The user's disk quota was exceeded. - - - Macro: int ESTALE - Stale NFS file handle. This indicates an internal confusion in - the NFS system which is due to file system rearrangements on the - server host. Repairing this condition usually requires unmounting - and remounting the NFS file system on the local host. - - - Macro: int EREMOTE - An attempt was made to NFS-mount a remote file system with a file - name that already specifies an NFS-mounted file. (This is an - error on some operating systems, but we expect it to work properly - on the GNU system, making this error code impossible.) - - - Macro: int EBADRPC - ??? - - - Macro: int ERPCMISMATCH - ??? - - - Macro: int EPROGUNAVAIL - ??? - - - Macro: int EPROGMISMATCH - ??? - - - Macro: int EPROCUNAVAIL - ??? - - - Macro: int ENOLCK - No locks available. This is used by the file locking facilities; - see *Note File Locks::.

This indicates that the function called - is not implemented at all, either in the C library itself or in the - operating system. When you get this error, you can be sure that - this particular function will always fail with `ENOSYS' unless you - install a new version of the C library or the operating system. - - - Macro: int ENOTSUP - Not supported. A function returns this error when certain - parameter values are valid, but the functionality they request is - not available. This can mean that the function does not implement - a particular command or option value or flag bit at all. For - functions that operate on some object given in a parameter, such - as a file descriptor or a port, it might instead mean that only - _that specific object_ (file descriptor, port, etc.) is unable to - support the other parameters given; different file descriptors - might support different ranges of parameter values. - - If the entire function is not available at all in the - implementation, it returns `ENOSYS' instead. - - - Macro: int EILSEQ - While decoding a multibyte character the function came along an - invalid or an incomplete sequence of bytes or the given wide - character is invalid. - - - Macro: int EBACKGROUND - In the GNU system, servers supporting the `term' protocol return - this error for certain operations when the caller is not in the - foreground process group of the terminal. Users do not usually - see this error because functions such as `read' and `write' - translate it into a `SIGTTIN' or `SIGTTOU' signal. *Note Job - Control::, for information on process groups and these signals. - - - Macro: int EDIED - In the GNU system, opening a file returns this error when the file - is translated by a program and the translator program dies while - starting up, before it has connected to the file. - - - Macro: int ED - The experienced user will know what is wrong. - - - Macro: int EGREGIOUS - You did *what*? - - - Macro: int EIEIO - Go home and have a glass of warm, dairy-fresh milk. - - - Macro: int EGRATUITOUS - This error code has no purpose. - - - Macro: int EBADMSG - - - Macro: int EIDRM - - - Macro: int EMULTIHOP - - - Macro: int ENODATA - - - Macro: int ENOLINK - - - Macro: int ENOMSG - - - Macro: int ENOSR - - - Macro: int ENOSTR - - - Macro: int EOVERFLOW - - - Macro: int EPROTO - - - Macro: int ETIME - - - Macro: int ECANCELED - Operation canceled; an asynchronous operation was canceled before - it completed. *Note Asynchronous I/O::.

The functions `strerror' -and `perror' give you the standard error message for a given error -code; the variable `program_invocation_short_name' gives you convenient -access to the name of the program that encountered the error. - - - Function: char * strerror (int ERRNUM) - The `strerror' function maps the error code (*note Checking for - Errors::) specified by the ERRNUM argument to a descriptive error - message string. The return value is a pointer to this string. - - The value ERRNUM normally comes from the variable `errno'. - - You should not modify the string returned by `strerror'. Also, if - you make subsequent calls to `strerror', the string might be - overwritten. (But it's guaranteed that no library function ever - calls `strerror' behind your back.) - - The function `strerror' is declared in `string.h'. - - - Function: char * strerror_r (int ERRNUM, char *BUF, size_t N) - The `strerror_r' function works like `strerror' but instead of - returning the error message in a statically allocated buffer - shared by all threads in the process, it returns a private copy - for the thread. This might be either some permanent global data or - a message string in the user supplied buffer starting at BUF with - the length of N bytes. - - At most N characters are written (including the NUL byte) so it is - up to the user to select the buffer large enough. - - This function should always be used in multi-threaded programs - since there is no way to guarantee the string returned by - `strerror' really belongs to the last call of the current thread. - - This function `strerror_r' is a GNU extension and it is declared in - `string.h'. - - - Function: void perror (const char *MESSAGE) - This function prints an error message to the stream `stderr'; see - *Note Standard Streams::. The orientation of `stderr' is not - changed. - - If you call `perror' with a MESSAGE that is either a null pointer - or an empty string, `perror' just prints the error message - corresponding to `errno', adding a trailing newline. - - If you supply a non-null MESSAGE argument, then `perror' prefixes - its output with this string. It adds a colon and a space - character to separate the MESSAGE from the error string - corresponding to `errno'. - - The function `perror' is declared in `stdio.h'. - - `strerror' and `perror' produce the exact same message for any given -error code; the precise text varies from system to system. On the GNU -system, the messages are fairly short; there are no multi-line messages -or embedded newlines. Each error message begins with a capital letter -and does not include any terminating punctuation. - - *Compatibility Note:* The `strerror' function was introduced in -ISO C89. Many older C systems do not support this function yet. - - Many programs that don't read input from the terminal are designed to -exit if any system call fails. By convention, the error message from -such a program should start with the program's name, sans directories. -You can find that name in the variable `program_invocation_short_name'; -the full file name is stored the variable `program_invocation_name'. - - - Variable: char * program_invocation_name - This variable's value is the name that was used to invoke the - program running in the current process. It is the same as - `argv[0]'. Note that this is not necessarily a useful file name; - often it contains no directory names. *Note Program Arguments::. - - - Variable: char * program_invocation_short_name - This variable's value is the name that was used to invoke the - program running in the current process, with directory names - removed. (That is to say, it is the same as - `program_invocation_name' minus everything up to the last slash, - if any.) - - The library initialization code sets up both of these variables -before calling `main'. - - *Portability Note:* These two variables are GNU extensions. If you -want your program to work with non-GNU libraries, you must save the -value of `argv[0]' in `main', and then strip off the directory names -yourself. We added these extensions to make it possible to write -self-contained error-reporting subroutines that require no explicit -cooperation from `main'. - - Here is an example showing how to handle failure to open a file -correctly. The function `open_sesame' tries to open the named file for -reading and returns a stream if successful. The `fopen' library -function returns a null pointer if it couldn't open the file for some -reason. In that situation, `open_sesame' constructs an appropriate -error message using the `strerror' function, and terminates the -program. If we were going to make some other library calls before -passing the error code to `strerror', we'd have to save it in a local -variable instead, because those other library functions might overwrite -`errno' in the meantime. - - #include - #include - #include - #include - - FILE * - open_sesame (char *name) - { - FILE *stream; - - errno = 0; - stream = fopen (name, "r"); - if (stream == NULL) - { - fprintf (stderr, "%s: Couldn't open file %s; %s\n", - program_invocation_short_name, name, strerror (errno)); - exit (EXIT_FAILURE); - } - else - return stream; - } - - Using `perror' has the advantage that the function is portable and -available on all systems implementing ISO C. But often the text -`perror' generates is not what is wanted and there is no way to extend -or change what `perror' does. The GNU coding standard, for instance, -requires error messages to be preceded by the program name and programs -which read some input files should should provide information about the -input file name and the line number in case an error is encountered -while reading the file. For these occasions there are two functions -available which are widely used throughout the GNU project. These -functions are declared in `error.h'. - - - Function: void error (int STATUS, int ERRNUM, const char *FORMAT, - ...) - The `error' function can be used to report general problems during - program execution. The FORMAT argument is a format string just - like those given to the `printf' family of functions. The - arguments required for the format can follow the FORMAT parameter. - Just like `perror', `error' also can report an error code in - textual form. But unlike `perror' the error value is explicitly - passed to the function in the ERRNUM parameter. This elimintates - the problem mentioned above that the error reporting function must - be called immediately after the function causing the error since - otherwise `errno' might have a different value. - - The `error' prints first the program name. If the application - defined a global variable `error_print_progname' and points it to a - function this function will be called to print the program name. - Otherwise the string from the global variable `program_name' is - used. The program name is followed by a colon and a space which - in turn is followed by the output produced by the format string. - If the ERRNUM parameter is non-zero the format string output is - followed by a colon and a space, followed by the error message for - the error code ERRNUM. In any case is the output terminated with - a newline. - - The output is directed to the `stderr' stream. If the `stderr' - wasn't oriented before the call it will be narrow-oriented - afterwards. - - The function will return unless the STATUS parameter has a - non-zero value. In this case the function will call `exit' with - the STATUS value for its parameter and therefore never return. If - `error' returns the global variable `error_message_count' is - incremented by one to keep track of the number of errors reported. - - - Function: void error_at_line (int STATUS, int ERRNUM, const char - *FNAME, unsigned int LINENO, const char *FORMAT, ...) - The `error_at_line' function is very similar to the `error' - function. The only difference are the additional parameters FNAME - and LINENO. The handling of the other parameters is identical to - that of `error' except that between the program name and the string - generated by the format string additional text is inserted. - - Directly following the program name a colon, followed by the file - name pointer to by FNAME, another colon, and a value of LINENO is - printed. - - This additional output of course is meant to be used to locate an - error in an input file (like a programming language source code - file etc). - - If the global variable `error_one_per_line' is set to a non-zero - value `error_at_line' will avoid printing consecutive messages for - the same file anem line. Repetition which are not directly - following each other are not caught. - - Just like `error' this function only returned if STATUS is zero. - Otherwise `exit' is called with the non-zero value. If `error' - returns the global variable `error_message_count' is incremented - by one to keep track of the number of errors reported. - - As mentioned above the `error' and `error_at_line' functions can be -customized by defining a variable named `error_print_progname'. - - - Variable: void (* error_print_progname ) (void) - If the `error_print_progname' variable is defined to a non-zero - value the function pointed to is called by `error' or - `error_at_line'. It is expected to print the program name or do - something similarly useful. - - The function is expected to be print to the `stderr' stream and - must be able to handle whatever orientation the stream has. - - The variable is global and shared by all threads. - - - Variable: unsigned int error_message_count - The `error_message_count' variable is incremented whenever one of - the functions `error' or `error_at_line' returns. The variable is - global and shared by all threads. - - - Variable: int error_one_per_line - The `error_one_per_line' variable influences only `error_at_line'. - Normally the `error_at_line' function creates output for every - invocation. If `error_one_per_line' is set to a non-zero value - `error_at_line' keeps track of the last file name and line number - for which an error was reported and avoid directly following - messages for the same file and line. This variable is global and - shared by all threads. - -A program which read some input file and reports errors in it could look -like this: - - { - char *line = NULL; - size_t len = 0; - unsigned int lineno = 0; - - error_message_count = 0; - while (! feof_unlocked (fp)) - { - ssize_t n = getline (&line, &len, fp); - if (n <= 0) - /* End of file or error. */ - break; - ++lineno; - - /* Process the line. */ - ... - - if (Detect error in line) - error_at_line (0, errval, filename, lineno, - "some error text %s", some_variable); - } - - if (error_message_count != 0) - error (EXIT_FAILURE, 0, "%u errors found", error_message_count); - } - - `error' and `error_at_line' are clearly the functions of choice and -enable the programmer to write applications which follow the GNU coding -standard. The GNU libc additionally contains functions which are used -in BSD for the same purpose. These functions are declared in `err.h'. -It is generally advised to not use these functions. They are included -only for compatibility. - - - Function: void warn (const char *FORMAT, ...) - The `warn' function is roughly equivalent to a call like - error (0, errno, format, the parameters) - - except that the global variables `error' respects and modifies are - not used. - - - Function: void vwarn (const char *FORMAT, va_list) - The `vwarn' function is just like `warn' except that the - parameters for the handling of the format string FORMAT are passed - in as an value of type `va_list'. - - - Function: void warnx (const char *FORMAT, ...) - The `warnx' function is roughly equivalent to a call like - error (0, 0, format, the parameters) - - except that the global variables `error' respects and modifies are - not used. The difference to `warn' is that no error number string - is printed. - - - Function: void vwarnx (const char *FORMAT, va_list) - The `vwarnx' function is just like `warnx' except that the - parameters for the handling of the format string FORMAT are passed - in as an value of type `va_list'. - - - Function: void err (int STATUS, const char *FORMAT, ...) - The `err' function is roughly equivalent to a call like - error (status, errno, format, the parameters) - - except that the global variables `error' respects and modifies are - not used and that the program is exited even if STATUS is zero. - - - Function: void verr (int STATUS, const char *FORMAT, va_list) - The `verr' function is just like `err' except that the parameters - for the handling of the format string FORMAT are passed in as an - value of type `va_list'. - - - Function: void errx (int STATUS, const char *FORMAT, ...) - The `errx' function is roughly equivalent to a call like - error (status, 0, format, the parameters) - - except that the global variables `error' respects and modifies are - not used and that the program is exited even if STATUS is zero. - The difference to `err' is that no error number string is printed. - - - Function: void verrx (int STATUS, const char *FORMAT, va_list) - The `verrx' function is just like `errx' except that the - parameters for the handling of the format string FORMAT are passed - in as an value of type `va_list'. - - -File: libc.info, Node: Memory, Next: Character Handling, Prev: Error Reporting, Up: Top - -Virtual Memory Allocation And Paging -************************************ - - This chapter describes how processes manage and use memory in a -system that uses the GNU C library. - - The GNU C Library has several functions for dynamically allocating -virtual memory in various ways. They vary in generality and in -efficiency. The library also provides functions for controlling paging -and allocation of real memory. - -* Menu: - -* Memory Concepts:: An introduction to concepts and terminology. -* Memory Allocation:: Allocating storage for your program data -* Locking Pages:: Preventing page faults -* Resizing the Data Segment:: `brk', `sbrk' - - Memory mapped I/O is not discussed in this chapter. *Note -Memory-mapped I/O::. - - -File: libc.info, Node: Memory Concepts, Next: Memory Allocation, Up: Memory - -Process Memory Concepts -======================= - - One of the most basic resources a process has available to it is -memory. There are a lot of different ways systems organize memory, but -in a typical one, each process has one linear virtual address space, -with addresses running from zero to some huge maximum. It need not be -contiguous; i.e. not all of these addresses actually can be used to -store data. - - The virtual memory is divided into pages (4 kilobytes is typical). -Backing each page of virtual memory is a page of real memory (called a -"frame") or some secondary storage, usually disk space. The disk space -might be swap space or just some ordinary disk file. Actually, a page -of all zeroes sometimes has nothing at all backing it - there's just a -flag saying it is all zeroes. - - The same frame of real memory or backing store can back multiple -virtual pages belonging to multiple processes. This is normally the -case, for example, with virtual memory occupied by GNU C library code. -The same real memory frame containing the `printf' function backs a -virtual memory page in each of the existing processes that has a -`printf' call in its program. - - In order for a program to access any part of a virtual page, the page -must at that moment be backed by ("connected to") a real frame. But -because there is usually a lot more virtual memory than real memory, the -pages must move back and forth between real memory and backing store -regularly, coming into real memory when a process needs to access them -and then retreating to backing store when not needed anymore. This -movement is called "paging". - - When a program attempts to access a page which is not at that moment -backed by real memory, this is known as a "page fault". When a page -fault occurs, the kernel suspends the process, places the page into a -real page frame (this is called "paging in" or "faulting in"), then -resumes the process so that from the process' point of view, the page -was in real memory all along. In fact, to the process, all pages always -seem to be in real memory. Except for one thing: the elapsed execution -time of an instruction that would normally be a few nanoseconds is -suddenly much, much, longer (because the kernel normally has to do I/O -to complete the page-in). For programs sensitive to that, the functions -described in *Note Locking Pages:: can control it. - - Within each virtual address space, a process has to keep track of -what is at which addresses, and that process is called memory -allocation. Allocation usually brings to mind meting out scarce -resources, but in the case of virtual memory, that's not a major goal, -because there is generally much more of it than anyone needs. Memory -allocation within a process is mainly just a matter of making sure that -the same byte of memory isn't used to store two different things. - - Processes allocate memory in two major ways: by exec and -programmatically. Actually, forking is a third way, but it's not very -interesting. *Note Creating a Process::. - - Exec is the operation of creating a virtual address space for a -process, loading its basic program into it, and executing the program. -It is done by the "exec" family of functions (e.g. `execl'). The -operation takes a program file (an executable), it allocates space to -load all the data in the executable, loads it, and transfers control to -it. That data is most notably the instructions of the program (the -"text"), but also literals and constants in the program and even some -variables: C variables with the static storage class (*note Memory -Allocation and C::). - - Once that program begins to execute, it uses programmatic allocation -to gain additional memory. In a C program with the GNU C library, there -are two kinds of programmatic allocation: automatic and dynamic. *Note -Memory Allocation and C::. - - Memory-mapped I/O is another form of dynamic virtual memory -allocation. Mapping memory to a file means declaring that the contents -of certain range of a process' addresses shall be identical to the -contents of a specified regular file. The system makes the virtual -memory initially contain the contents of the file, and if you modify -the memory, the system writes the same modification to the file. Note -that due to the magic of virtual memory and page faults, there is no -reason for the system to do I/O to read the file, or allocate real -memory for its contents, until the program accesses the virtual memory. -*Note Memory-mapped I/O::. - - Just as it programmatically allocates memory, the program can -programmatically deallocate ("free") it. You can't free the memory -that was allocated by exec. When the program exits or execs, you might -say that all its memory gets freed, but since in both cases the address -space ceases to exist, the point is really moot. *Note Program -Termination::. - - A process' virtual address space is divided into segments. A -segment is a contiguous range of virtual addresses. Three important -segments are: - - * The "text segment" contains a program's instructions and literals - and static constants. It is allocated by exec and stays the same - size for the life of the virtual address space. - - * The "data segment" is working storage for the program. It can be - preallocated and preloaded by exec and the process can extend or - shrink it by calling functions as described in *Note Resizing the - Data Segment::. Its lower end is fixed. - - * The "stack segment" contains a program stack. It grows as the - stack grows, but doesn't shrink when the stack shrinks. - - - -File: libc.info, Node: Memory Allocation, Next: Locking Pages, Prev: Memory Concepts, Up: Memory - -Allocating Storage For Program Data -=================================== - - This section covers how ordinary programs manage storage for their -data, including the famous `malloc' function and some fancier facilities -special the GNU C library and GNU Compiler. - -* Menu: - -* Memory Allocation and C:: How to get different kinds of allocation in C. -* Unconstrained Allocation:: The `malloc' facility allows fully general - dynamic allocation. -* Allocation Debugging:: Finding memory leaks and not freed memory. -* Obstacks:: Obstacks are less general than malloc - but more efficient and convenient. -* Variable Size Automatic:: Allocation of variable-sized blocks - of automatic storage that are freed when the - calling function returns. - - -File: libc.info, Node: Memory Allocation and C, Next: Unconstrained Allocation, Up: Memory Allocation - -Memory Allocation in C Programs -------------------------------- - - The C language supports two kinds of memory allocation through the -variables in C programs: - - * "Static allocation" is what happens when you declare a static or - global variable. Each static or global variable defines one block - of space, of a fixed size. The space is allocated once, when your - program is started (part of the exec operation), and is never - freed. - - * "Automatic allocation" happens when you declare an automatic - variable, such as a function argument or a local variable. The - space for an automatic variable is allocated when the compound - statement containing the declaration is entered, and is freed when - that compound statement is exited. - - In GNU C, the size of the automatic storage can be an expression - that varies. In other C implementations, it must be a constant. - - A third important kind of memory allocation, "dynamic allocation", -is not supported by C variables but is available via GNU C library -functions. - -Dynamic Memory Allocation -......................... - - "Dynamic memory allocation" is a technique in which programs -determine as they are running where to store some information. You need -dynamic allocation when the amount of memory you need, or how long you -continue to need it, depends on factors that are not known before the -program runs. - - For example, you may need a block to store a line read from an input -file; since there is no limit to how long a line can be, you must -allocate the memory dynamically and make it dynamically larger as you -read more of the line. - - Or, you may need a block for each record or each definition in the -input data; since you can't know in advance how many there will be, you -must allocate a new block for each record or definition as you read it. - - When you use dynamic allocation, the allocation of a block of memory -is an action that the program requests explicitly. You call a function -or macro when you want to allocate space, and specify the size with an -argument. If you want to free the space, you do so by calling another -function or macro. You can do these things whenever you want, as often -as you want. - - Dynamic allocation is not supported by C variables; there is no -storage class "dynamic", and there can never be a C variable whose -value is stored in dynamically allocated space. The only way to get -dynamically allocated memory is via a system call (which is generally -via a GNU C library function call), and the only way to refer to -dynamically allocated space is through a pointer. Because it is less -convenient, and because the actual process of dynamic allocation -requires more computation time, programmers generally use dynamic -allocation only when neither static nor automatic allocation will serve. - - For example, if you want to allocate dynamically some space to hold a -`struct foobar', you cannot declare a variable of type `struct foobar' -whose contents are the dynamically allocated space. But you can -declare a variable of pointer type `struct foobar *' and assign it the -address of the space. Then you can use the operators `*' and `->' on -this pointer variable to refer to the contents of the space: - - { - struct foobar *ptr - = (struct foobar *) malloc (sizeof (struct foobar)); - ptr->name = x; - ptr->next = current_foobar; - current_foobar = ptr; - } - - -File: libc.info, Node: Unconstrained Allocation, Next: Allocation Debugging, Prev: Memory Allocation and C, Up: Memory Allocation - -Unconstrained Allocation ------------------------- - - The most general dynamic allocation facility is `malloc'. It allows -you to allocate blocks of memory of any size at any time, make them -bigger or smaller at any time, and free the blocks individually at any -time (or never). - -* Menu: - -* Basic Allocation:: Simple use of `malloc'. -* Malloc Examples:: Examples of `malloc'. `xmalloc'. -* Freeing after Malloc:: Use `free' to free a block you - got with `malloc'. -* Changing Block Size:: Use `realloc' to make a block - bigger or smaller. -* Allocating Cleared Space:: Use `calloc' to allocate a - block and clear it. -* Efficiency and Malloc:: Efficiency considerations in use of - these functions. -* Aligned Memory Blocks:: Allocating specially aligned memory. -* Malloc Tunable Parameters:: Use `mallopt' to adjust allocation - parameters. -* Heap Consistency Checking:: Automatic checking for errors. -* Hooks for Malloc:: You can use these hooks for debugging - programs that use `malloc'. -* Statistics of Malloc:: Getting information about how much - memory your program is using. -* Summary of Malloc:: Summary of `malloc' and related functions. - - -File: libc.info, Node: Basic Allocation, Next: Malloc Examples, Up: Unconstrained Allocation - -Basic Memory Allocation -....................... - - To allocate a block of memory, call `malloc'. The prototype for -this function is in `stdlib.h'. - - - Function: void * malloc (size_t SIZE) - This function returns a pointer to a newly allocated block SIZE - bytes long, or a null pointer if the block could not be allocated. - - The contents of the block are undefined; you must initialize it -yourself (or use `calloc' instead; *note Allocating Cleared Space::). -Normally you would cast the value as a pointer to the kind of object -that you want to store in the block. Here we show an example of doing -so, and of initializing the space with zeros using the library function -`memset' (*note Copying and Concatenation::): - - struct foo *ptr; - ... - ptr = (struct foo *) malloc (sizeof (struct foo)); - if (ptr == 0) abort (); - memset (ptr, 0, sizeof (struct foo)); - - You can store the result of `malloc' into any pointer variable -without a cast, because ISO C automatically converts the type `void *' -to another type of pointer when necessary. But the cast is necessary -in contexts other than assignment operators or if you might want your -code to run in traditional C. - - Remember that when allocating space for a string, the argument to -`malloc' must be one plus the length of the string. This is because a -string is terminated with a null character that doesn't count in the -"length" of the string but does need space. For example: - - char *ptr; - ... - ptr = (char *) malloc (length + 1); - -*Note Representation of Strings::, for more information about this. - - -File: libc.info, Node: Malloc Examples, Next: Freeing after Malloc, Prev: Basic Allocation, Up: Unconstrained Allocation - -Examples of `malloc' -.................... - - If no more space is available, `malloc' returns a null pointer. You -should check the value of _every_ call to `malloc'. It is useful to -write a subroutine that calls `malloc' and reports an error if the -value is a null pointer, returning only if the value is nonzero. This -function is conventionally called `xmalloc'. Here it is: - - void * - xmalloc (size_t size) - { - register void *value = malloc (size); - if (value == 0) - fatal ("virtual memory exhausted"); - return value; - } - - Here is a real example of using `malloc' (by way of `xmalloc'). The -function `savestring' will copy a sequence of characters into a newly -allocated null-terminated string: - - char * - savestring (const char *ptr, size_t len) - { - register char *value = (char *) xmalloc (len + 1); - value[len] = '\0'; - return (char *) memcpy (value, ptr, len); - } - - The block that `malloc' gives you is guaranteed to be aligned so -that it can hold any type of data. In the GNU system, the address is -always a multiple of eight on most systems, and a multiple of 16 on -64-bit systems. Only rarely is any higher boundary (such as a page -boundary) necessary; for those cases, use `memalign', `posix_memalign' -or `valloc' (*note Aligned Memory Blocks::). - - Note that the memory located after the end of the block is likely to -be in use for something else; perhaps a block already allocated by -another call to `malloc'. If you attempt to treat the block as longer -than you asked for it to be, you are liable to destroy the data that -`malloc' uses to keep track of its blocks, or you may destroy the -contents of another block. If you have already allocated a block and -discover you want it to be bigger, use `realloc' (*note Changing Block -Size::). - diff -u -udbrN glibc-2.3.2/manual/libc.info-30 glibc-2.3.2-200304020432/manual/libc.info-30 --- glibc-2.3.2/manual/libc.info-30 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-30 Thu Jan 1 01:00:00 1970 @@ -1,1306 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

The system facilities for the user to edit -input are disabled in noncanonical mode, so that all input characters -(unless they are special for signal or flow-control purposes) are passed -to the application program exactly as typed. It is up to the -application program to give the user ways to edit the input, if -appropriate. - - Noncanonical mode offers special parameters called MIN and TIME for -controlling whether and how long to wait for input to be available. You -can even use them to avoid ever waiting--to return immediately with -whatever input is available, or with no input. - - The MIN and TIME are stored in elements of the `c_cc' array, which -is a member of the `struct termios' structure. Each element of this -array has a particular role, and each element has a symbolic constant -that stands for the index of that element. `VMIN' and `VMAX' are the -names for the indices in the array of the MIN and TIME slots. - - - Macro: int VMIN - This is the subscript for the MIN slot in the `c_cc' array. Thus, - `TERMIOS.c_cc[VMIN]' is the value itself. - - The MIN slot is only meaningful in noncanonical input mode; it - specifies the minimum number of bytes that must be available in the - input queue in order for `read' to return. - - - Macro: int VTIME - This is the subscript for the TIME slot in the `c_cc' array. Thus, - `TERMIOS.c_cc[VTIME]' is the value itself. - - The TIME slot is only meaningful in noncanonical input mode; it - specifies how long to wait for input before returning, in units of - 0.1 seconds. - - The MIN and TIME values interact to determine the criterion for when -`read' should return; their precise meanings depend on which of them -are nonzero. There are four possible cases: - - * Both TIME and MIN are nonzero. - - In this case, TIME specifies how long to wait after each input - character to see if more input arrives. After the first character - received, `read' keeps waiting until either MIN bytes have arrived - in all, or TIME elapses with no further input. - - `read' always blocks until the first character arrives, even if - TIME elapses first. `read' can return more than MIN characters if - more than MIN happen to be in the queue. - - * Both MIN and TIME are zero. - - In this case, `read' always returns immediately with as many - characters as are available in the queue, up to the number - requested. If no input is immediately available, `read' returns a - value of zero. - - * MIN is zero but TIME has a nonzero value. - - In this case, `read' waits for time TIME for input to become - available; the availability of a single byte is enough to satisfy - the read request and cause `read' to return. When it returns, it - returns as many characters as are available, up to the number - requested. If no input is available before the timer expires, - `read' returns a value of zero. - - * TIME is zero but MIN has a nonzero value. - - In this case, `read' waits until at least MIN bytes are available - in the queue. At that time, `read' returns as many characters as - are available, up to the number requested. `read' can return more - than MIN characters if more than MIN happen to be in the queue. - - What happens if MIN is 50 and you ask to read just 10 bytes? -Normally, `read' waits until there are 50 bytes in the buffer (or, more -generally, the wait condition described above is satisfied), and then -reads 10 of them, leaving the other 40 buffered in the operating system -for a subsequent call to `read'. - - *Portability note:* On some systems, the MIN and TIME slots are -actually the same as the EOF and EOL slots. This causes no serious -problem because the MIN and TIME slots are used only in noncanonical -input and the EOF and EOL slots are used only in canonical input, but it -isn't very clean.

The following - `errno' conditions are defined for this function: - - `ENOENT' - There are no free master pseudo-terminals available. - - This function is a GNU extension. - - - Function: int grantpt (int FILEDES) - The `grantpt' function changes the ownership and access permission - of the slave pseudo-terminal device corresponding to the master - pseudo-terminal device associated with the file descriptor - FILEDES. The owner is set from the real user ID of the calling - process (*note Process Persona::), and the group is set to a - special group (typically "tty") or from the real group ID of the - calling process. The access permission is set such that the file - is both readable and writable by the owner and only writable by - the group. - - On some systems this function is implemented by invoking a special - `setuid' root program (*note How Change Persona::). As a - consequence, installing a signal handler for the `SIGCHLD' signal - (*note Job Control Signals::) may interfere with a call to - `grantpt'. - - The normal return value from `grantpt' is 0; a value of -1 is - returned in case of failure. The following `errno' error - conditions are defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `EINVAL' - The FILEDES argument is not associated with a master - pseudo-terminal device. - - `EACCES' - The slave pseudo-terminal device corresponding to the master - associated with FILEDES could not be accessed. - - - - Function: int unlockpt (int FILEDES) - The `unlockpt' function unlocks the slave pseudo-terminal device - corresponding to the master pseudo-terminal device associated with - the file descriptor FILEDES. On many systems, the slave can only - be opened after unlocking, so portable applications should always - call `unlockpt' before trying to open the slave. - - The normal return value from `unlockpt' is 0; a value of -1 is - returned in case of failure. The following `errno' error - conditions are defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `EINVAL' - The FILEDES argument is not associated with a master - pseudo-terminal device. - - - Function: char * ptsname (int FILEDES) - If the file descriptor FILEDES is associated with a master - pseudo-terminal device, the `ptsname' function returns a pointer - to a statically-allocated, null-terminated string containing the - file name of the associated slave pseudo-terminal file.

For example, an FTP server might report every -connection it gets. The kernel might report hardware failures on a disk -drive. A DNS server might report usage statistics at regular intervals. - - Some of these messages need to be brought to a system administrator's -attention immediately. And it may not be just any system administrator -- there may be a particular system administrator who deals with a -particular kind of message. Other messages just need to be recorded for -future reference if there is a problem. Still others may need to have -information extracted from them by an automated process that generates -monthly reports. - - To deal with these messages, most Unix systems have a facility called -"Syslog." It is generally based on a daemon called "Syslogd" Syslogd -listens for messages on a Unix domain socket named `/dev/log'. Based -on classification information in the messages and its configuration -file (usually `/etc/syslog.conf'), Syslogd routes them in various ways. -Some of the popular routings are: - - * Write to the system console - - * Mail to a specific user - - * Write to a log file - - * Pass to another daemon - - * Discard - - Syslogd can also handle messages from other systems. It listens on -the `syslog' UDP port as well as the local socket for messages. - - Syslog can handle messages from the kernel itself. But the kernel -doesn't write to `/dev/log'; rather, another daemon (sometimes called -"Klogd") extracts messages from the kernel and passes them on to Syslog -as any other process would (and it properly identifies them as messages -from the kernel). - - Syslog can even handle messages that the kernel issued before -Syslogd or Klogd was running. A Linux kernel, for example, stores -startup messages in a kernel message ring and they are normally still -there when Klogd later starts up. Assuming Syslogd is running by the -time Klogd starts, Klogd then passes everything in the message ring to -it. - - In order to classify messages for disposition, Syslog requires any -process that submits a message to it to provide two pieces of -classification information with it: - -facility - This identifies who submitted the message. There are a small - number of facilities defined. The kernel, the mail subsystem, and - an FTP server are examples of recognized facilities. For the - complete list, *Note syslog; vsyslog::. Keep in mind that these - are essentially arbitrary classifications. "Mail subsystem" - doesn't have any more meaning than the system administrator gives - to it. - -priority - This tells how important the content of the message is. Examples - of defined priority values are: debug, informational, warning, - critical. For the complete list, *Note syslog; vsyslog::. Except - for the fact that the priorities have a defined order, the meaning - of each of these priorities is entirely determined by the system - administrator. - - A "facility/priority" is a number that indicates both the facility -and the priority. - - *Warning:* This terminology is not universal. Some people use -"level" to refer to the priority and "priority" to refer to the -combination of facility and priority. A Linux kernel has a concept of a -message "level," which corresponds both to a Syslog priority and to a -Syslog facility/priority (It can be both because the facility code for -the kernel is zero, and that makes priority and facility/priority the -same value). - - The GNU C library provides functions to submit messages to Syslog. -They do it by writing to the `/dev/log' socket. *Note Submitting -Syslog Messages::. - - The GNU C library functions only work to submit messages to the -Syslog facility on the same system. To submit a message to the Syslog -facility on another system, use the socket I/O functions to write a UDP -datagram to the `syslog' UDP port on that system. *Note Sockets::. - - -File: libc.info, Node: Submitting Syslog Messages, Prev: Overview of Syslog, Up: Syslog - -Submitting Syslog Messages -========================== - - The GNU C library provides functions to submit messages to the Syslog -facility: - -* Menu: - -* openlog:: Open connection to Syslog -* syslog; vsyslog:: Submit message to Syslog -* closelog:: Close connection to Syslog -* setlogmask:: Cause certain messages to be ignored -* Syslog Example:: Example of all of the above - - These functions only work to submit messages to the Syslog facility -on the same system.

This is intended to - identify the source of the message, and people conventionally set - it to the name of the program that will submit the messages. - - If IDENT is NULL, or if `openlog' is not called, the default - identification string used in Syslog messages will be the program - name, taken from argv[0]. - - Please note that the string pointer IDENT will be retained - internally by the Syslog routines. You must not free the memory - that IDENT points to. It is also dangerous to pass a reference to - an automatic variable since leaving the scope would mean ending the - lifetime of the variable. If you want to change the IDENT string, - you must call `openlog' again; overwriting the string pointed to by - IDENT is not thread-safe. - - You can cause the Syslog routines to drop the reference to IDENT - and go back to the default string (the program name taken from - argv[0]), by calling `closelog': *Note closelog::. - - In particular, if you are writing code for a shared library that - might get loaded and then unloaded (e.g. a PAM module), and you - use `openlog', you must call `closelog' before any point where - your library might get unloaded, as in this example: - - #include - - void - shared_library_function (void) - { - openlog ("mylibrary", option, priority); - - syslog (LOG_INFO, "shared library has been invoked"); - - closelog (); - } - - Without the call to `closelog', future invocations of `syslog' by - the program using the shared library may crash, if the library gets - unloaded and the memory containing the string `"mylibrary"' becomes - unmapped. This is a limitation of the BSD syslog interface. - - `openlog' may or may not open the `/dev/log' socket, depending on - OPTION. If it does, it tries to open it and connect it as a - stream socket. If that doesn't work, it tries to open it and - connect it as a datagram socket. The socket has the "Close on - Exec" attribute, so the kernel will close it if the process - performs an exec. - - You don't have to use `openlog'. If you call `syslog' without - having called `openlog', `syslog' just opens the connection - implicitly and uses defaults for the information in IDENT and - OPTIONS. - - OPTIONS is a bit string, with the bits as defined by the following - single bit masks: - - `LOG_PERROR' - If on, `openlog' sets up the connection so that any `syslog' - on this connection writes its message to the calling process' - Standard Error stream in addition to submitting it to Syslog. - If off, `syslog' does not write the message to Standard - Error. - - `LOG_CONS' - If on, `openlog' sets up the connection so that a `syslog' on - this connection that fails to submit a message to Syslog - writes the message instead to system console. If off, - `syslog' does not write to the system console (but of course - Syslog may write messages it receives to the console). - - `LOG_PID' - When on, `openlog' sets up the connection so that a `syslog' - on this connection inserts the calling process' Process ID - (PID) into the message. When off, `openlog' does not insert - the PID. - - `LOG_NDELAY' - When on, `openlog' opens and connects the `/dev/log' socket. - When off, a future `syslog' call must open and connect the - socket. - - *Portability note:* In early systems, the sense of this bit - was exactly the opposite. - - `LOG_ODELAY' - This bit does nothing. It exists for backward compatibility. - - If any other bit in OPTIONS is on, the result is undefined. - - FACILITY is the default facility code for this connection. A - `syslog' on this connection that specifies default facility causes - this facility to be associated with the message. See `syslog' for - possible values. A value of zero means the default default, which - is `LOG_USER'. - - If a Syslog connection is already open when you call `openlog', - `openlog' "reopens" the connection. Reopening is like opening - except that if you specify zero for the default facility code, the - default facility code simply remains unchanged and if you specify - LOG_NDELAY and the socket is already open and connected, `openlog' - just leaves it that way. - - - -File: libc.info, Node: syslog; vsyslog, Next: closelog, Prev: openlog, Up: Submitting Syslog Messages - -syslog, vsyslog ---------------- - - The symbols referred to in this section are declared in the file -`syslog.h'. - - - Function: void syslog (int FACILITY_PRIORITY, char *FORMAT, ...) - `syslog' submits a message to the Syslog facility.

Errors are measured in "units of the last place". This is a -measure for the relative error. For a number z with the representation -d.d...d*2^e (we assume IEEE floating-point numbers with base 2) the ULP -is represented by - - |d.d...d - (z / 2^e)| / 2^(p - 1) - -where p is the number of bits in the mantissa of the floating-point -number representation. Ideally the error for all functions is always -less than 0.5ulps. Using rounding bits this is also possible and -normally implemented for the basic operations. To achieve the same for -the complex math functions requires a lot more work and this has not -yet been done. - - Therefore many of the functions in the math library have errors. The -table lists the maximum error for each function which is exposed by one -of the existing tests in the test suite. The table tries to cover as -much as possible and list the actual maximum error (or at least a -ballpark figure) but this is often not achieved due to the large search -space. - - The table lists the ULP values for different architectures. -Different architectures have different results since their hardware -support for floating-point operations varies and also the existing -hardware support is different. -

The numbers generated are not truly random; -typically, they form a sequence that repeats periodically, with a period -so large that you can ignore it for ordinary purposes. The random -number generator works by remembering a "seed" value which it uses to -compute the next random number and also to compute a new seed. - - Although the generated numbers look unpredictable within one run of a -program, the sequence of numbers is _exactly the same_ from one run to -the next. This is because the initial seed is always the same. This -is convenient when you are debugging a program, but it is unhelpful if -you want the program to behave unpredictably. If you want a different -pseudo-random series each time your program runs, you must specify a -different seed each time. For ordinary purposes, basing the seed on the -current time works well. - - You can obtain repeatable sequences of numbers on a particular -machine type by specifying the same initial seed value for the random -number generator. There is no standard meaning for a particular seed -value; the same seed, used in different C libraries or on different CPU -types, will give you different random numbers. - - The GNU library supports the standard ISO C random number functions -plus two other sets derived from BSD and SVID. The BSD and ISO C -functions provide identical, somewhat limited functionality. If only a -small number of random bits are required, we recommend you use the -ISO C interface, `rand' and `srand'. The SVID functions provide a more -flexible interface, which allows better random number generator -algorithms, provides more random bits (up to 48) per call, and can -provide random floating-point numbers. These functions are required by -the XPG standard and therefore will be present in all modern Unix -systems. - -* Menu: - -* ISO Random:: `rand' and friends. -* BSD Random:: `random' and friends. -* SVID Random:: `drand48' and friends. - - -File: libc.info, Node: ISO Random, Next: BSD Random, Up: Pseudo-Random Numbers - -ISO C Random Number Functions ------------------------------ - - This section describes the random number functions that are part of -the ISO C standard. - - To use these facilities, you should include the header file -`stdlib.h' in your program. - - - Macro: int RAND_MAX - The value of this macro is an integer constant representing the - largest value the `rand' function can return. In the GNU library, - it is `2147483647', which is the largest signed integer - representable in 32 bits. In other libraries, it may be as low as - `32767'. - - - Function: int rand (void) - The `rand' function returns the next pseudo-random number in the - series. The value ranges from `0' to `RAND_MAX'. - - - Function: void srand (unsigned int SEED) - This function establishes SEED as the seed for a new series of - pseudo-random numbers. If you call `rand' before a seed has been - established with `srand', it uses the value `1' as a default seed. - - To produce a different pseudo-random series each time your program - is run, do `srand (time (0))'. - - POSIX.1 extended the C standard functions to support reproducible -random numbers in multi-threaded programs. However, the extension is -badly designed and unsuitable for serious work. - - - Function: int rand_r (unsigned int *SEED) - This function returns a random number in the range 0 to `RAND_MAX' - just as `rand' does. However, all its state is stored in the SEED - argument. This means the RNG's state can only have as many bits - as the type `unsigned int' has. This is far too few to provide a - good RNG. - - If your program requires a reentrant RNG, we recommend you use the - reentrant GNU extensions to the SVID random number generator. The - POSIX.1 interface should only be used when the GNU extensions are - not available. - - -File: libc.info, Node: BSD Random, Next: SVID Random, Prev: ISO Random, Up: Pseudo-Random Numbers - -BSD Random Number Functions ---------------------------- - - This section describes a set of random number generation functions -that are derived from BSD. There is no advantage to using these -functions with the GNU C library; we support them for BSD compatibility -only. - - The prototypes for these functions are in `stdlib.h'. - - - Function: long int random (void) - This function returns the next pseudo-random number in the - sequence. The value returned ranges from `0' to `RAND_MAX'. - - *Note:* Temporarily this function was defined to return a - `int32_t' value to indicate that the return value always contains - 32 bits even if `long int' is wider. The standard demands it - differently. Users must always be aware of the 32-bit limitation, - though. - - - Function: void srandom (unsigned int SEED) - The `srandom' function sets the state of the random number - generator based on the integer SEED. If you supply a SEED value - of `1', this will cause `random' to reproduce the default set of - random numbers. - - To produce a different set of pseudo-random numbers each time your - program runs, do `srandom (time (0))'. - - - Function: void * initstate (unsigned int SEED, void *STATE, size_t - SIZE) - The `initstate' function is used to initialize the random number - generator state. The argument STATE is an array of SIZE bytes, - used to hold the state information. It is initialized based on - SEED. The size must be between 8 and 256 bytes, and should be a - power of two. The bigger the STATE array, the better. - - The return value is the previous value of the state information - array. You can use this value later as an argument to `setstate' - to restore that state. - - - Function: void * setstate (void *STATE) - The `setstate' function restores the random number state - information STATE. The argument must have been the result of a - previous call to INITSTATE or SETSTATE. - - The return value is the previous value of the state information - array. You can use this value later as an argument to `setstate' - to restore that state. - - If the function fails the return value is `NULL'. - - The four functions described so far in this section all work on a -state which is shared by all threads. The state is not directly -accessible to the user and can only be modified by these functions. -This makes it hard to deal with situations where each thread should -have its own pseudo-random number generator. - - The GNU C library contains four additional functions which contain -the state as an explicit parameter and therefore make it possible to -handle thread-local PRNGs. Beside this there are no difference. In -fact, the four functions already discussed are implemented internally -using the following interfaces. - - The `stdlib.h' header contains a definition of the following type: - - - Data Type: struct random_data - Objects of type `struct random_data' contain the information - necessary to represent the state of the PRNG. Although a complete - definition of the type is present the type should be treated as - opaque. - - The functions modifying the state follow exactly the already -described functions. - - - Function: int random_r (struct random_data *restrict BUF, int32_t - *restrict RESULT) - The `random_r' function behaves exactly like the `random' function - except that it uses and modifies the state in the object pointed - to by the first parameter instead of the global state. - - - Function: int srandom_r (unsigned int SEED, struct random_data *BUF) - The `srandom_r' function behaves exactly like the `srandom' - function except that it uses and modifies the state in the object - pointed to by the second parameter instead of the global state. - - - Function: int initstate_r (unsigned int SEED, char *restrict - STATEBUF, size_t STATELEN, struct random_data *restrict BUF) - The `initstate_r' function behaves exactly like the `initstate' - function except that it uses and modifies the state in the object - pointed to by the fourth parameter instead of the global state. - - - Function: int setstate_r (char *restrict STATEBUF, struct - random_data *restrict BUF) - The `setstate_r' function behaves exactly like the `setstate' - function except that it uses and modifies the state in the object - pointed to by the first parameter instead of the global state. - - -File: libc.info, Node: SVID Random, Prev: BSD Random, Up: Pseudo-Random Numbers - -SVID Random Number Function ---------------------------- - - The C library on SVID systems contains yet another kind of random -number generator functions. They use a state of 48 bits of data. The -user can choose among a collection of functions which return the random -bits in different forms. - - Generally there are two kinds of function. The first uses a state of -the random number generator which is shared among several functions and -by all threads of the process. The second requires the user to handle -the state. - - All functions have in common that they use the same congruential -formula with the same constants. The formula is - - Y = (a * X + c) mod m - -where X is the state of the generator at the beginning and Y the state -at the end. `a' and `c' are constants determining the way the -generator works. By default they are - - a = 0x5DEECE66D = 25214903917 - c = 0xb = 11 - -but they can also be changed by the user. `m' is of course 2^48 since -the state consists of a 48-bit array. - - The prototypes for these functions are in `stdlib.h'. - - - Function: double drand48 (void) - This function returns a `double' value in the range of `0.0' to - `1.0' (exclusive). The random bits are determined by the global - state of the random number generator in the C library. - - Since the `double' type according to IEEE 754 has a 52-bit - mantissa this means 4 bits are not initialized by the random number - generator. These are (of course) chosen to be the least - significant bits and they are initialized to `0'. - - - Function: double erand48 (unsigned short int XSUBI[3]) - This function returns a `double' value in the range of `0.0' to - `1.0' (exclusive), similarly to `drand48'. The argument is an - array describing the state of the random number generator. - - This function can be called subsequently since it updates the - array to guarantee random numbers. The array should have been - initialized before initial use to obtain reproducible results. - - - Function: long int lrand48 (void) - The `lrand48' function returns an integer value in the range of - `0' to `2^31' (exclusive). Even if the size of the `long int' - type can take more than 32 bits, no higher numbers are returned. - The random bits are determined by the global state of the random - number generator in the C library. - - - Function: long int nrand48 (unsigned short int XSUBI[3]) - This function is similar to the `lrand48' function in that it - returns a number in the range of `0' to `2^31' (exclusive) but the - state of the random number generator used to produce the random - bits is determined by the array provided as the parameter to the - function. - - The numbers in the array are updated afterwards so that subsequent - calls to this function yield different results (as is expected of - a random number generator). The array should have been - initialized before the first call to obtain reproducible results. - - - Function: long int mrand48 (void) - The `mrand48' function is similar to `lrand48'. The only - difference is that the numbers returned are in the range `-2^31' to - `2^31' (exclusive). - - - Function: long int jrand48 (unsigned short int XSUBI[3]) - The `jrand48' function is similar to `nrand48'. The only - difference is that the numbers returned are in the range `-2^31' to - `2^31' (exclusive). For the `xsubi' parameter the same - requirements are necessary. - - The internal state of the random number generator can be initialized -in several ways. The methods differ in the completeness of the -information provided. - - - Function: void srand48 (long int SEEDVAL) - The `srand48' function sets the most significant 32 bits of the - internal state of the random number generator to the least - significant 32 bits of the SEEDVAL parameter. The lower 16 bits - are initialized to the value `0x330E'. Even if the `long int' - type contains more than 32 bits only the lower 32 bits are used. - - Owing to this limitation, initialization of the state of this - function is not very useful. But it makes it easy to use a - construct like `srand48 (time (0))'. - - A side-effect of this function is that the values `a' and `c' from - the internal state, which are used in the congruential formula, - are reset to the default values given above. This is of - importance once the user has called the `lcong48' function (see - below). - - - Function: unsigned short int * seed48 (unsigned short int SEED16V[3]) - The `seed48' function initializes all 48 bits of the state of the - internal random number generator from the contents of the parameter - SEED16V. Here the lower 16 bits of the first element of SEE16V - initialize the least significant 16 bits of the internal state, - the lower 16 bits of `SEED16V[1]' initialize the mid-order 16 bits - of the state and the 16 lower bits of `SEED16V[2]' initialize the - most significant 16 bits of the state. - - Unlike `srand48' this function lets the user initialize all 48 bits - of the state. - - The value returned by `seed48' is a pointer to an array containing - the values of the internal state before the change. This might be - useful to restart the random number generator at a certain state. - Otherwise the value can simply be ignored. - - As for `srand48', the values `a' and `c' from the congruential - formula are reset to the default values. - - There is one more function to initialize the random number generator -which enables you to specify even more information by allowing you to -change the parameters in the congruential formula. - - - Function: void lcong48 (unsigned short int PARAM[7]) - The `lcong48' function allows the user to change the complete state - of the random number generator. Unlike `srand48' and `seed48', - this function also changes the constants in the congruential - formula. - - From the seven elements in the array PARAM the least significant - 16 bits of the entries `PARAM[0]' to `PARAM[2]' determine the - initial state, the least significant 16 bits of `PARAM[3]' to - `PARAM[5]' determine the 48 bit constant `a' and `PARAM[6]' - determines the 16-bit value `c'. - - All the above functions have in common that they use the global -parameters for the congruential formula. In multi-threaded programs it -might sometimes be useful to have different parameters in different -threads. For this reason all the above functions have a counterpart -which works on a description of the random number generator in the -user-supplied buffer instead of the global state. - - Please note that it is no problem if several threads use the global -state if all threads use the functions which take a pointer to an array -containing the state. The random numbers are computed following the -same loop but if the state in the array is different all threads will -obtain an individual random number generator. - - The user-supplied buffer must be of type `struct drand48_data'. -This type should be regarded as opaque and not manipulated directly. - - - Function: int drand48_r (struct drand48_data *BUFFER, double *RESULT) - This function is equivalent to the `drand48' function with the - difference that it does not modify the global random number - generator parameters but instead the parameters in the buffer - supplied through the pointer BUFFER. The random number is - returned in the variable pointed to by RESULT. - - The return value of the function indicates whether the call - succeeded. If the value is less than `0' an error occurred and - ERRNO is set to indicate the problem. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int erand48_r (unsigned short int XSUBI[3], struct - drand48_data *BUFFER, double *RESULT) - The `erand48_r' function works like `erand48', but in addition it - takes an argument BUFFER which describes the random number - generator. The state of the random number generator is taken from - the `xsubi' array, the parameters for the congruential formula - from the global random number generator data. The random number - is returned in the variable pointed to by RESULT. - - The return value is non-negative if the call succeeded. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int lrand48_r (struct drand48_data *BUFFER, double *RESULT) - This function is similar to `lrand48', but in addition it takes a - pointer to a buffer describing the state of the random number - generator just like `drand48'. - - If the return value of the function is non-negative the variable - pointed to by RESULT contains the result. Otherwise an error - occurred. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int nrand48_r (unsigned short int XSUBI[3], struct - drand48_data *BUFFER, long int *RESULT) - The `nrand48_r' function works like `nrand48' in that it produces - a random number in the range `0' to `2^31'. But instead of using - the global parameters for the congruential formula it uses the - information from the buffer pointed to by BUFFER. The state is - described by the values in XSUBI. - - If the return value is non-negative the variable pointed to by - RESULT contains the result. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int mrand48_r (struct drand48_data *BUFFER, double *RESULT) - This function is similar to `mrand48' but like the other reentrant - functions it uses the random number generator described by the - value in the buffer pointed to by BUFFER. - - If the return value is non-negative the variable pointed to by - RESULT contains the result. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int jrand48_r (unsigned short int XSUBI[3], struct - drand48_data *BUFFER, long int *RESULT) - The `jrand48_r' function is similar to `jrand48'. Like the other - reentrant functions of this function family it uses the - congruential formula parameters from the buffer pointed to by - BUFFER. - - If the return value is non-negative the variable pointed to by - RESULT contains the result. - - This function is a GNU extension and should not be used in portable - programs. - - Before any of the above functions are used the buffer of type -`struct drand48_data' should be initialized. The easiest way to do -this is to fill the whole buffer with null bytes, e.g. by - - memset (buffer, '\0', sizeof (struct drand48_data)); - -Using any of the reentrant functions of this family now will -automatically initialize the random number generator to the default -values for the state and the parameters of the congruential formula. - - The other possibility is to use any of the functions which explicitly -initialize the buffer. Though it might be obvious how to initialize the -buffer from looking at the parameter to the function, it is highly -recommended to use these functions since the result might not always be -what you expect. - - - Function: int srand48_r (long int SEEDVAL, struct drand48_data - *BUFFER) - The description of the random number generator represented by the - information in BUFFER is initialized similarly to what the function - `srand48' does. The state is initialized from the parameter - SEEDVAL and the parameters for the congruential formula are - initialized to their default values. - - If the return value is non-negative the function call succeeded. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int seed48_r (unsigned short int SEED16V[3], struct - drand48_data *BUFFER) - This function is similar to `srand48_r' but like `seed48' it - initializes all 48 bits of the state from the parameter SEED16V. - - If the return value is non-negative the function call succeeded. - It does not return a pointer to the previous state of the random - number generator like the `seed48' function does. If the user - wants to preserve the state for a later re-run s/he can copy the - whole buffer pointed to by BUFFER. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int lcong48_r (unsigned short int PARAM[7], struct - drand48_data *BUFFER) - This function initializes all aspects of the random number - generator described in BUFFER with the data in PARAM. Here it is - especially true that the function does more than just copying the - contents of PARAM and BUFFER. More work is required and therefore - it is important to use this function rather than initializing the - random number generator directly. - - If the return value is non-negative the function call succeeded. - - This function is a GNU extension and should not be used in portable - programs. - - -File: libc.info, Node: FP Function Optimizations, Prev: Pseudo-Random Numbers, Up: Mathematics - -Is Fast Code or Small Code preferred? -===================================== - - If an application uses many floating point functions it is often the -case that the cost of the function calls themselves is not negligible. -Modern processors can often execute the operations themselves very -fast, but the function call disrupts the instruction pipeline. - - For this reason the GNU C Library provides optimizations for many of -the frequently-used math functions. When GNU CC is used and the user -activates the optimizer, several new inline functions and macros are -defined. These new functions and macros have the same names as the -library functions and so are used instead of the latter. In the case of -inline functions the compiler will decide whether it is reasonable to -use them, and this decision is usually correct. - - This means that no calls to the library functions may be necessary, -and can increase the speed of generated code significantly. The -drawback is that code size will increase, and the increase is not -always negligible. - - There are two kind of inline functions: Those that give the same -result as the library functions and others that might not set `errno' -and might have a reduced precision and/or argument range in comparison -with the library functions. The latter inline functions are only -available if the flag `-ffast-math' is given to GNU CC. - - In cases where the inline functions and macros are not wanted the -symbol `__NO_MATH_INLINES' should be defined before any system header is -included. This will ensure that only library functions are used. Of -course, it can be determined for each file in the project whether -giving this option is preferable or not. - - Not all hardware implements the entire IEEE 754 standard, and even -if it does there may be a substantial performance penalty for using some -of its features.

The GNU C compiler extends the language to contain long -long integers as well. - - The C integer types were intended to allow code to be portable among -machines with different inherent data sizes (word sizes), so each type -may have different ranges on different machines. The problem with this -is that a program often needs to be written for a particular range of -integers, and sometimes must be written for a particular size of -storage, regardless of what machine the program runs on. - - To address this problem, the GNU C library contains C type -definitions you can use to declare integers that meet your exact needs. -Because the GNU C library header files are customized to a specific -machine, your program source code doesn't have to be. - - These `typedef's are in `stdint.h'. - - If you require that an integer be represented in exactly N bits, use -one of the following types, with the obvious mapping to bit size and -signedness: - - * int8_t - - * int16_t - - * int32_t - - * int64_t - - * uint8_t - - * uint16_t - - * uint32_t - - * uint64_t - - If your C compiler and target machine do not allow integers of a -certain size, the corresponding above type does not exist. - - If you don't need a specific storage size, but want the smallest data -structure with _at least_ N bits, use one of these: - - * int_least8_t - - * int_least16_t - - * int_least32_t - - * int_least64_t - - * uint_least8_t - - * uint_least16_t - - * uint_least32_t - - * uint_least64_t - - If you don't need a specific storage size, but want the data -structure that allows the fastest access while having at least N bits -(and among data structures with the same access speed, the smallest -one), use one of these: - - * int_fast8_t - - * int_fast16_t - - * int_fast32_t - - * int_fast64_t - - * uint_fast8_t - - * uint_fast16_t - - * uint_fast32_t - - * uint_fast64_t - - If you want an integer with the widest range possible on the -platform on which it is being used, use one of the following. If you -use these, you should write code that takes into account the variable -size and range of the integer. - - * intmax_t - - * uintmax_t - - The GNU C library also provides macros that tell you the maximum and -minimum possible values for each integer data type. The macro names -follow these examples: `INT32_MAX', `UINT8_MAX', `INT_FAST32_MIN', -`INT_LEAST64_MIN', `UINTMAX_MAX', `INTMAX_MAX', `INTMAX_MIN'. Note -that there are no macros for unsigned integer minima. These are always -zero. - - There are similar macros for use with C's built in integer types -which should come with your C compiler. These are described in *Note -Data Type Measurements::. - - Don't forget you can use the C `sizeof' function with any of these -data types to get the number of bytes of storage each uses. - - -File: libc.info, Node: Integer Division, Next: Floating Point Numbers, Prev: Integers, Up: Arithmetic - -Integer Division -================ - - This section describes functions for performing integer division. -These functions are redundant when GNU CC is used, because in GNU C the -`/' operator always rounds towards zero.

The remainder has the same sign as the -numerator. - - These functions are specified to return a result R such that the -value `R.quot*DENOMINATOR + R.rem' equals NUMERATOR. - - To use these facilities, you should include the header file -`stdlib.h' in your program. - - - Data Type: div_t - This is a structure type used to hold the result returned by the - `div' function. It has the following members: - - `int quot' - The quotient from the division. - - `int rem' - The remainder from the division. - - - Function: div_t div (int NUMERATOR, int DENOMINATOR) - This function `div' computes the quotient and remainder from the - division of NUMERATOR by DENOMINATOR, returning the result in a - structure of type `div_t'. - - If the result cannot be represented (as in a division by zero), the - behavior is undefined. - - Here is an example, albeit not a very useful one. - - div_t result; - result = div (20, -6); - - Now `result.quot' is `-3' and `result.rem' is `2'. - - - Data Type: ldiv_t - This is a structure type used to hold the result returned by the - `ldiv' function. It has the following members: - - `long int quot' - The quotient from the division. - - `long int rem' - The remainder from the division. - - (This is identical to `div_t' except that the components are of - type `long int' rather than `int'.) - - - Function: ldiv_t ldiv (long int NUMERATOR, long int DENOMINATOR) - The `ldiv' function is similar to `div', except that the arguments - are of type `long int' and the result is returned as a structure - of type `ldiv_t'. - - - Data Type: lldiv_t - This is a structure type used to hold the result returned by the - `lldiv' function.

Floating-point numbers have three parts: the "mantissa", the -"exponent", and the "sign bit". The real number represented by a -floating-point value is given by (s ? -1 : 1) * 2^e * M where s is the -sign bit, e the exponent, and M the mantissa. *Note Floating Point -Concepts::, for details. (It is possible to have a different "base" -for the exponent, but all modern hardware uses 2.) - - Floating-point numbers can represent a finite subset of the real -numbers. While this subset is large enough for most purposes, it is -important to remember that the only reals that can be represented -exactly are rational numbers that have a terminating binary expansion -shorter than the width of the mantissa. Even simple fractions such as -1/5 can only be approximated by floating point. - - Mathematical operations and functions frequently need to produce -values that are not representable. Often these values can be -approximated closely enough for practical purposes, but sometimes they -can't. Historically there was no way to tell when the results of a -calculation were inaccurate. Modern computers implement the IEEE 754 -standard for numerical computations, which defines a framework for -indicating to the program when the results of calculation are not -trustworthy. This framework consists of a set of "exceptions" that -indicate why a result could not be represented, and the special values -"infinity" and "not a number" (NaN). - - -File: libc.info, Node: Floating Point Classes, Next: Floating Point Errors, Prev: Floating Point Numbers, Up: Arithmetic - -Floating-Point Number Classification Functions -============================================== - - ISO C99 defines macros that let you determine what sort of -floating-point number a variable holds. - - - Macro: int fpclassify (_float-type_ X) - This is a generic macro which works on all floating-point types and - which returns a value of type `int'. The possible values are: - - `FP_NAN' - The floating-point number X is "Not a Number" (*note Infinity - and NaN::) - - `FP_INFINITE' - The value of X is either plus or minus infinity (*note - Infinity and NaN::) - - `FP_ZERO' - The value of X is zero. In floating-point formats like - IEEE 754, where zero can be signed, this value is also - returned if X is negative zero. - - `FP_SUBNORMAL' - Numbers whose absolute value is too small to be represented - in the normal format are represented in an alternate, - "denormalized" format (*note Floating Point Concepts::). - This format is less precise but can represent values closer - to zero. `fpclassify' returns this value for values of X in - this alternate format. - - `FP_NORMAL' - This value is returned for all other values of X. It - indicates that there is nothing special about the number. - - - `fpclassify' is most useful if more than one property of a number -must be tested. There are more specific macros which only test one -property at a time. Generally these macros execute faster than -`fpclassify', since there is special hardware support for them. You -should therefore use the specific macros whenever possible. - - - Macro: int isfinite (_float-type_ X) - This macro returns a nonzero value if X is finite: not plus or - minus infinity, and not NaN. It is equivalent to - - (fpclassify (x) != FP_NAN && fpclassify (x) != FP_INFINITE) - - `isfinite' is implemented as a macro which accepts any - floating-point type. - - - Macro: int isnormal (_float-type_ X) - This macro returns a nonzero value if X is finite and normalized. - It is equivalent to - - (fpclassify (x) == FP_NORMAL) - - - Macro: int isnan (_float-type_ X) - This macro returns a nonzero value if X is NaN. It is equivalent - to - - (fpclassify (x) == FP_NAN) - - Another set of floating-point classification functions was provided -by BSD. The GNU C library also supports these functions; however, we -recommend that you use the ISO C99 macros in new code. Those are -standard and will be available more widely. Also, since they are -macros, you do not have to worry about the type of their argument. - - - Function: int isinf (double X) - - Function: int isinff (float X) - - Function: int isinfl (long double X) - This function returns `-1' if X represents negative infinity, `1' - if X represents positive infinity, and `0' otherwise. - - - Function: int isnan (double X) - - Function: int isnanf (float X) - - Function: int isnanl (long double X) - This function returns a nonzero value if X is a "not a number" - value, and zero otherwise. - - *Note:* The `isnan' macro defined by ISO C99 overrides the BSD - function.

Each corresponds to a particular sort of error, -such as overflow. - - When exceptions occur (when exceptions are "raised", in the language -of the standard), one of two things can happen. By default the -exception is simply noted in the floating-point "status word", and the -program continues as if nothing had happened. The operation produces a -default value, which depends on the exception (see the table below). -Your program can check the status word to find out which exceptions -happened. - - Alternatively, you can enable "traps" for exceptions. In that case, -when an exception is raised, your program will receive the `SIGFPE' -signal. The default action for this signal is to terminate the -program. *Note Signal Handling::, for how you can change the effect of -the signal. - - In the System V math library, the user-defined function `matherr' is -called when certain exceptions occur inside math library functions. -However, the Unix98 standard deprecates this interface. We support it -for historical compatibility, but recommend that you do not use it in -new programs. - -The exceptions defined in IEEE 754 are: - -`Invalid Operation' - This exception is raised if the given operands are invalid for the - operation to be performed. Examples are (see IEEE 754, section 7): - 1. Addition or subtraction: oo - oo. (But oo + oo = oo). - - 2. Multiplication: 0 * oo. - - 3. Division: 0/0 or oo/oo. - - 4. Remainder: x REM y, where y is zero or x is infinite. - - 5. Square root if the operand is less then zero. More - generally, any mathematical function evaluated outside its - domain produces this exception. - - 6. Conversion of a floating-point number to an integer or decimal - string, when the number cannot be represented in the target - format (due to overflow, infinity, or NaN). - - 7. Conversion of an unrecognizable input string. - - 8. Comparison via predicates involving < or >, when one or other - of the operands is NaN. You can prevent this exception by - using the unordered comparison functions instead; see *Note - FP Comparison Functions::. - - If the exception does not trap, the result of the operation is NaN. - -`Division by Zero' - This exception is raised when a finite nonzero number is divided - by zero. If no trap occurs the result is either +oo or -oo, - depending on the signs of the operands. - -`Overflow' - This exception is raised whenever the result cannot be represented - as a finite value in the precision format of the destination. If - no trap occurs the result depends on the sign of the intermediate - result and the current rounding mode (IEEE 754, section 7.3): - 1. Round to nearest carries all overflows to oo with the sign of - the intermediate result. - - 2. Round toward 0 carries all overflows to the largest - representable finite number with the sign of the intermediate - result. - - 3. Round toward -oo carries positive overflows to the largest - representable finite number and negative overflows to -oo. - - 4. Round toward oo carries negative overflows to the most - negative representable finite number and positive overflows - to oo. - - Whenever the overflow exception is raised, the inexact exception - is also raised. - -`Underflow' - The underflow exception is raised when an intermediate result is - too small to be calculated accurately, or if the operation's - result rounded to the destination precision is too small to be - normalized. - - When no trap is installed for the underflow exception, underflow is - signaled (via the underflow flag) only when both tininess and loss - of accuracy have been detected. If no trap handler is installed - the operation continues with an imprecise small value, or zero if - the destination precision cannot hold the small exact result. - -`Inexact' - This exception is signalled if a rounded result is not exact (such - as when calculating the square root of two) or a result overflows - without an overflow trap. - - -File: libc.info, Node: Infinity and NaN, Next: Status bit operations, Prev: FP Exceptions, Up: Floating Point Errors - -Infinity and NaN ----------------- - - IEEE 754 floating point numbers can represent positive or negative -infinity, and "NaN" (not a number). These three values arise from -calculations whose result is undefined or cannot be represented -accurately. You can also deliberately set a floating-point variable to -any of them, which is sometimes useful. Some examples of calculations -that produce infinity or NaN: - - 1/0 = oo - log (0) = -oo - sqrt (-1) = NaN - - When a calculation produces any of these values, an exception also -occurs; see *Note FP Exceptions::. - - The basic operations and math functions all accept infinity and NaN -and produce sensible output. Infinities propagate through calculations -as one would expect: for example, 2 + oo = oo, 4/oo = 0, atan (oo) = -pi/2. NaN, on the other hand, infects any calculation that involves -it. Unless the calculation would produce the same result no matter -what real value replaced NaN, the result is NaN. - - In comparison operations, positive infinity is larger than all values -except itself and NaN, and negative infinity is smaller than all values -except itself and NaN. NaN is "unordered": it is not equal to, greater -than, or less than anything, _including itself_. `x == x' is false if -the value of `x' is NaN. You can use this to test whether a value is -NaN or not, but the recommended way to test for NaN is with the `isnan' -function (*note Floating Point Classes::). In addition, `<', `>', -`<=', and `>=' will raise an exception when applied to NaNs. - - `math.h' defines macros that allow you to explicitly set a variable -to infinity or NaN. - - - Macro: float INFINITY - An expression representing positive infinity. It is equal to the - value produced by mathematical operations like `1.0 / 0.0'. - `-INFINITY' represents negative infinity. - - You can test whether a floating-point value is infinite by - comparing it to this macro. However, this is not recommended; you - should use the `isfinite' macro instead. *Note Floating Point - Classes::. - - This macro was introduced in the ISO C99 standard. - - - Macro: float NAN - An expression representing a value which is "not a number". This - macro is a GNU extension, available only on machines that support - the "not a number" value--that is to say, on all machines that - support IEEE floating point. - - You can use `#ifdef NAN' to test whether the machine supports NaN. - (Of course, you must arrange for GNU extensions to be visible, - such as by defining `_GNU_SOURCE', and then you must include - `math.h'.) - - IEEE 754 also allows for another unusual value: negative zero. This -value is produced when you divide a positive number by negative -infinity, or when a negative result is smaller than the limits of -representation. Negative zero behaves identically to zero in all -calculations, unless you explicitly test the sign bit with `signbit' or -`copysign'. - - -File: libc.info, Node: Status bit operations, Next: Math Error Reporting, Prev: Infinity and NaN, Up: Floating Point Errors - -Examining the FPU status word ------------------------------ - - ISO C99 defines functions to query and manipulate the floating-point -status word. You can use these functions to check for untrapped -exceptions when it's convenient, rather than worrying about them in the -middle of a calculation. - - These constants represent the various IEEE 754 exceptions. Not all -FPUs report all the different exceptions. Each constant is defined if -and only if the FPU you are compiling for supports that exception, so -you can test for FPU support with `#ifdef'. They are defined in -`fenv.h'. - -`FE_INEXACT' - The inexact exception. - -`FE_DIVBYZERO' - The divide by zero exception. - -`FE_UNDERFLOW' - The underflow exception. - -`FE_OVERFLOW' - The overflow exception. - -`FE_INVALID' - The invalid exception. - - The macro `FE_ALL_EXCEPT' is the bitwise OR of all exception macros -which are supported by the FP implementation. - - These functions allow you to clear exception flags, test for -exceptions, and save and restore the set of exceptions flagged. - - - Function: int feclearexcept (int EXCEPTS) - This function clears all of the supported exception flags - indicated by EXCEPTS. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - - - Function: int feraiseexcept (int EXCEPTS) - This function raises the supported exceptions indicated by - EXCEPTS. If more than one exception bit in EXCEPTS is set the - order in which the exceptions are raised is undefined except that - overflow (`FE_OVERFLOW') or underflow (`FE_UNDERFLOW') are raised - before inexact (`FE_INEXACT'). Whether for overflow or underflow - the inexact exception is also raised is also implementation - dependent. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - - - Function: int fetestexcept (int EXCEPTS) - Test whether the exception flags indicated by the parameter EXCEPT - are currently set. If any of them are, a nonzero value is returned - which specifies which exceptions are set. Otherwise the result is - zero. - - To understand these functions, imagine that the status word is an -integer variable named STATUS. `feclearexcept' is then equivalent to -`status &= ~excepts' and `fetestexcept' is equivalent to `(status & -excepts)'. The actual implementation may be very different, of course. - - Exception flags are only cleared when the program explicitly -requests it, by calling `feclearexcept'. If you want to check for -exceptions from a set of calculations, you should clear all the flags -first. Here is a simple example of the way to use `fetestexcept': - - { - double f; - int raised; - feclearexcept (FE_ALL_EXCEPT); - f = compute (); - raised = fetestexcept (FE_OVERFLOW | FE_INVALID); - if (raised & FE_OVERFLOW) { /* ... */ } - if (raised & FE_INVALID) { /* ... */ } - /* ... */ - } - - You cannot explicitly set bits in the status word. You can, however, -save the entire status word and restore it later. This is done with the -following functions: - - - Function: int fegetexceptflag (fexcept_t *FLAGP, int EXCEPTS) - This function stores in the variable pointed to by FLAGP an - implementation-defined value representing the current setting of - the exception flags indicated by EXCEPTS. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - - - Function: int fesetexceptflag (const fexcept_t *FLAGP, int - EXCEPTS) This function restores the flags for the exceptions - indicated by EXCEPTS to the values stored in the variable pointed - to by FLAGP. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - - Note that the value stored in `fexcept_t' bears no resemblance to -the bit mask returned by `fetestexcept'. The type may not even be an -integer. Do not attempt to modify an `fexcept_t' variable. - diff -u -udbrN glibc-2.3.2/manual/libc.info-34 glibc-2.3.2-200304020432/manual/libc.info-34 --- glibc-2.3.2/manual/libc.info-34 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-34 Thu Jan 1 01:00:00 1970 @@ -1,1120 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

Even if they are mathematically defined, -their result may be larger or smaller than the range representable by -their return type. These are known as "domain errors", "overflows", and -"underflows", respectively. Math functions do several things when one -of these errors occurs. In this manual we will refer to the complete -response as "signalling" a domain error, overflow, or underflow. - - When a math function suffers a domain error, it raises the invalid -exception and returns NaN. It also sets ERRNO to `EDOM'; this is for -compatibility with old systems that do not support IEEE 754 exception -handling. Likewise, when overflow occurs, math functions raise the -overflow exception and return oo or -oo as appropriate. They also set -ERRNO to `ERANGE'. When underflow occurs, the underflow exception is -raised, and zero (appropriately signed) is returned. ERRNO may be set -to `ERANGE', but this is not guaranteed. - - Some of the math functions are defined mathematically to result in a -complex value over parts of their domains. The most familiar example of -this is taking the square root of a negative number. The complex math -functions, such as `csqrt', will return the appropriate complex value -in this case. The real-valued functions, such as `sqrt', will signal a -domain error. - - Some older hardware does not support infinities. On that hardware, -overflows instead return a particular very large number (usually the -largest representable number). `math.h' defines macros you can use to -test for overflow on both old and new hardware. - - - Macro: double HUGE_VAL - - Macro: float HUGE_VALF - - Macro: long double HUGE_VALL - An expression representing a particular very large number.

This -ensures that results are as precise as the input data. IEEE 754 -defines four possible rounding modes: - -Round to nearest. - This is the default mode. It should be used unless there is a - specific need for one of the others. In this mode results are - rounded to the nearest representable value. If the result is - midway between two representable values, the even representable is - chosen. "Even" here means the lowest-order bit is zero. This - rounding mode prevents statistical bias and guarantees numeric - stability: round-off errors in a lengthy calculation will remain - smaller than half of `FLT_EPSILON'. - -Round toward plus Infinity. - All results are rounded to the smallest representable value which - is greater than the result. - -Round toward minus Infinity. - All results are rounded to the largest representable value which - is less than the result. - -Round toward zero. - All results are rounded to the largest representable value whose - magnitude is less than that of the result. In other words, if the - result is negative it is rounded up; if it is positive, it is - rounded down. - -`fenv.h' defines constants which you can use to refer to the various -rounding modes. Each one will be defined if and only if the FPU -supports the corresponding rounding mode. - -`FE_TONEAREST' - Round to nearest. - -`FE_UPWARD' - Round toward +oo. - -`FE_DOWNWARD' - Round toward -oo. - -`FE_TOWARDZERO' - Round toward zero. - - Underflow is an unusual case. Normally, IEEE 754 floating point -numbers are always normalized (*note Floating Point Concepts::). -Numbers smaller than 2^r (where r is the minimum exponent, -`FLT_MIN_RADIX-1' for FLOAT) cannot be represented as normalized -numbers. Rounding all such numbers to zero or 2^r would cause some -algorithms to fail at 0. Therefore, they are left in denormalized -form. That produces loss of precision, since some bits of the mantissa -are stolen to indicate the decimal point. - - If a result is too small to be represented as a denormalized number, -it is rounded to zero. However, the sign of the result is preserved; if -the calculation was negative, the result is "negative zero". Negative -zero can also result from some operations on infinity, such as 4/-oo. -Negative zero behaves identically to zero except when the `copysign' or -`signbit' functions are used to check the sign bit directly. - - At any time one of the above four rounding modes is selected.

In C, traps result in the program -receiving the `SIGFPE' signal; see *Note Signal Handling::. - - *Note:* IEEE 754 says that trap handlers are given details of the -exceptional situation, and can set the result value. C signals do not -provide any mechanism to pass this information back and forth. -Trapping exceptions in C is therefore not very useful. - - It is sometimes necessary to save the state of the floating-point -unit while you perform some calculation. The library provides functions -which save and restore the exception flags, the set of exceptions that -generate traps, and the rounding mode. This information is known as the -"floating-point environment". - - The functions to save and restore the floating-point environment all -use a variable of type `fenv_t' to store information. This type is -defined in `fenv.h'. Its size and contents are implementation-defined. -You should not attempt to manipulate a variable of this type directly. - - To save the state of the FPU, use one of these functions: - - - Function: int fegetenv (fenv_t *ENVP) - Store the floating-point environment in the variable pointed to by - ENVP. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - - - Function: int feholdexcept (fenv_t *ENVP) - Store the current floating-point environment in the object pointed - to by ENVP. Then clear all exception flags, and set the FPU to - trap no exceptions. Not all FPUs support trapping no exceptions; - if `feholdexcept' cannot set this mode, it returns nonzero value. - If it succeeds, it returns zero. - - The functions which restore the floating-point environment can take -these kinds of arguments: - - * Pointers to `fenv_t' objects, which were initialized previously by - a call to `fegetenv' or `feholdexcept'. - - * The special macro `FE_DFL_ENV' which represents the floating-point - environment as it was available at program start. - - * Implementation defined macros with names starting with `FE_' and - having type `fenv_t *'. - - If possible, the GNU C Library defines a macro `FE_NOMASK_ENV' - which represents an environment where every exception raised - causes a trap to occur. You can test for this macro using - `#ifdef'. It is only defined if `_GNU_SOURCE' is defined. - - Some platforms might define other predefined environments. - -To set the floating-point environment, you can use either of these -functions: - - - Function: int fesetenv (const fenv_t *ENVP) - Set the floating-point environment to that described by ENVP. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - - - Function: int feupdateenv (const fenv_t *ENVP) - Like `fesetenv', this function sets the floating-point environment - to that described by ENVP. However, if any exceptions were - flagged in the status word before `feupdateenv' was called, they - remain flagged after the call. In other words, after `feupdateenv' - is called, the status word is the bitwise OR of the previous - status word and the one saved in ENVP. - - The function returns zero in case the operation was successful, a - non-zero value otherwise. - -To control for individual exceptions if raising them causes a trap to -occur, you can use the following two functions. - - *Portability Note:* These functions are all GNU extensions. - - - Function: int feenableexcept (int EXCEPTS) - This functions enables traps for each of the exceptions as - indicated by the parameter EXCEPT.

Which - characters are whitespace is determined by the `isspace' - function (*note Classification of Characters::). These are - discarded. - - * An optional plus or minus sign (`+' or `-'). - - * A nonempty sequence of digits in the radix specified by BASE. - - If BASE is zero, decimal radix is assumed unless the series of - digits begins with `0' (specifying octal radix), or `0x' or - `0X' (specifying hexadecimal radix); in other words, the same - syntax used for integer constants in C. - - Otherwise BASE must have a value between `2' and `36'. If - BASE is `16', the digits may optionally be preceded by `0x' - or `0X'. If base has no legal value the value returned is - `0l' and the global variable `errno' is set to `EINVAL'. - - * Any remaining characters in the string. If TAILPTR is not a - null pointer, `strtol' stores a pointer to this tail in - `*TAILPTR'. - - If the string is empty, contains only whitespace, or does not - contain an initial substring that has the expected syntax for an - integer in the specified BASE, no conversion is performed. In - this case, `strtol' returns a value of zero and the value stored in - `*TAILPTR' is the value of STRING. - - In a locale other than the standard `"C"' locale, this function - may recognize additional implementation-dependent syntax. - - If the string has valid syntax for an integer but the value is not - representable because of overflow, `strtol' returns either - `LONG_MAX' or `LONG_MIN' (*note Range of Type::), as appropriate - for the sign of the value. It also sets `errno' to `ERANGE' to - indicate there was overflow. - - You should not check for errors by examining the return value of - `strtol', because the string might be a valid representation of - `0l', `LONG_MAX', or `LONG_MIN'. Instead, check whether TAILPTR - points to what you expect after the number (e.g. `'\0'' if the - string should end after the number). You also need to clear ERRNO - before the call and check it afterward, in case there was overflow. - - There is an example at the end of this section. - - - Function: long int wcstol (const wchar_t *restrict STRING, wchar_t - **restrict TAILPTR, int BASE) - The `wcstol' function is equivalent to the `strtol' function in - nearly all aspects but handles wide character strings. - - The `wcstol' function was introduced in Amendment 1 of ISO C90. - - - Function: unsigned long int strtoul (const char *retrict STRING, - char **restrict TAILPTR, int BASE) - The `strtoul' ("string-to-unsigned-long") function is like - `strtol' except it converts to an `unsigned long int' value. The - syntax is the same as described above for `strtol'. The value - returned on overflow is `ULONG_MAX' (*note Range of Type::). - - If STRING depicts a negative number, `strtoul' acts the same as - STRTOL but casts the result to an unsigned integer. That means - for example that `strtoul' on `"-1"' returns `ULONG_MAX' and an - input more negative than `LONG_MIN' returns (`ULONG_MAX' + 1) / 2. - - `strtoul' sets ERRNO to `EINVAL' if BASE is out of range, or - `ERANGE' on overflow. - - - Function: unsigned long int wcstoul (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoul' function is equivalent to the `strtoul' function in - nearly all aspects but handles wide character strings. - - The `wcstoul' function was introduced in Amendment 1 of ISO C90. - - - Function: long long int strtoll (const char *restrict STRING, char - **restrict TAILPTR, int BASE) - The `strtoll' function is like `strtol' except that it returns a - `long long int' value, and accepts numbers with a correspondingly - larger range. - - If the string has valid syntax for an integer but the value is not - representable because of overflow, `strtoll' returns either - `LONG_LONG_MAX' or `LONG_LONG_MIN' (*note Range of Type::), as - appropriate for the sign of the value. It also sets `errno' to - `ERANGE' to indicate there was overflow. - - The `strtoll' function was introduced in ISO C99. - - - Function: long long int wcstoll (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoll' function is equivalent to the `strtoll' function in - nearly all aspects but handles wide character strings. - - The `wcstoll' function was introduced in Amendment 1 of ISO C90. - - - Function: long long int strtoq (const char *restrict STRING, char - **restrict TAILPTR, int BASE) - `strtoq' ("string-to-quad-word") is the BSD name for `strtoll'. - - - Function: long long int wcstoq (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoq' function is equivalent to the `strtoq' function in - nearly all aspects but handles wide character strings. - - The `wcstoq' function is a GNU extension. - - - Function: unsigned long long int strtoull (const char *restrict - STRING, char **restrict TAILPTR, int BASE) - The `strtoull' function is related to `strtoll' the same way - `strtoul' is related to `strtol'. - - The `strtoull' function was introduced in ISO C99. - - - Function: unsigned long long int wcstoull (const wchar_t *restrict - STRING, wchar_t **restrict TAILPTR, int BASE) - The `wcstoull' function is equivalent to the `strtoull' function - in nearly all aspects but handles wide character strings. - - The `wcstoull' function was introduced in Amendment 1 of ISO C90. - - - Function: unsigned long long int strtouq (const char *restrict - STRING, char **restrict TAILPTR, int BASE) - `strtouq' is the BSD name for `strtoull'. - - - Function: unsigned long long int wcstouq (const wchar_t *restrict - STRING, wchar_t **restrict TAILPTR, int BASE) - The `wcstouq' function is equivalent to the `strtouq' function in - nearly all aspects but handles wide character strings. - - The `wcstoq' function is a GNU extension. - - - Function: intmax_t strtoimax (const char *restrict STRING, char - **restrict TAILPTR, int BASE) - The `strtoimax' function is like `strtol' except that it returns a - `intmax_t' value, and accepts numbers of a corresponding range. - - If the string has valid syntax for an integer but the value is not - representable because of overflow, `strtoimax' returns either - `INTMAX_MAX' or `INTMAX_MIN' (*note Integers::), as appropriate - for the sign of the value. It also sets `errno' to `ERANGE' to - indicate there was overflow. - - See *Note Integers:: for a description of the `intmax_t' type. The - `strtoimax' function was introduced in ISO C99. - - - Function: intmax_t wcstoimax (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoimax' function is equivalent to the `strtoimax' function - in nearly all aspects but handles wide character strings. - - The `wcstoimax' function was introduced in ISO C99. - - - Function: uintmax_t strtoumax (const char *restrict STRING, char - **restrict TAILPTR, int BASE) - The `strtoumax' function is related to `strtoimax' the same way - that `strtoul' is related to `strtol'. - - See *Note Integers:: for a description of the `intmax_t' type. The - `strtoumax' function was introduced in ISO C99. - - - Function: uintmax_t wcstoumax (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoumax' function is equivalent to the `strtoumax' function - in nearly all aspects but handles wide character strings. - - The `wcstoumax' function was introduced in ISO C99. - - - Function: long int atol (const char *STRING) - This function is similar to the `strtol' function with a BASE - argument of `10', except that it need not detect overflow errors. - The `atol' function is provided mostly for compatibility with - existing code; using `strtol' is more robust. - - - Function: int atoi (const char *STRING) - This function is like `atol', except that it returns an `int'. - The `atoi' function is also considered obsolete; use `strtol' - instead. - - - Function: long long int atoll (const char *STRING) - This function is similar to `atol', except it returns a `long long - int'. - - The `atoll' function was introduced in ISO C99.

In this -manual, we use a rigorous terminology to avoid confusion, and the only -thing we use the simple word "time" for is to talk about the abstract -concept. - - A "calendar time" is a point in the time continuum, for example -November 4, 1990 at 18:02.5 UTC. Sometimes this is called "absolute -time". - - We don't speak of a "date", because that is inherent in a calendar -time. - - An "interval" is a contiguous part of the time continuum between two -calendar times, for example the hour between 9:00 and 10:00 on July 4, -1980. - - An "elapsed time" is the length of an interval, for example, 35 -minutes. People sometimes sloppily use the word "interval" to refer to -the elapsed time of some interval. - - An "amount of time" is a sum of elapsed times, which need not be of -any specific intervals. For example, the amount of time it takes to -read a book might be 9 hours, independently of when and in how many -sittings it is read. - - A "period" is the elapsed time of an interval between two events, -especially when they are part of a sequence of regularly repeating -events. - - "CPU time" is like calendar time, except that it is based on the -subset of the time continuum when a particular process is actively -using a CPU. CPU time is, therefore, relative to a process. - - "Processor time" is an amount of time that a CPU is in use. In -fact, it's a basic system resource, since there's a limit to how much -can exist in any given interval (that limit is the elapsed time of the -interval times the number of CPUs in the processor). People often call -this CPU time, but we reserve the latter term in this manual for the -definition above. - - -File: libc.info, Node: Elapsed Time, Next: Processor And CPU Time, Prev: Time Basics, Up: Date and Time - -Elapsed Time -============ - - One way to represent an elapsed time is with a simple arithmetic data -type, as with the following function to compute the elapsed time between -two calendar times. This function is declared in `time.h'. - - - Function: double difftime (time_t TIME1, time_t TIME0) - The `difftime' function returns the number of seconds of elapsed - time between calendar time TIME1 and calendar time TIME0, as a - value of type `double'. The difference ignores leap seconds - unless leap second support is enabled. - - In the GNU system, you can simply subtract `time_t' values. But on - other systems, the `time_t' data type might use some other encoding - where subtraction doesn't work directly. - - The GNU C library provides two data types specifically for -representing an elapsed time. They are used by various GNU C library -functions, and you can use them for your own purposes too. They're -exactly the same except that one has a resolution in microseconds, and -the other, newer one, is in nanoseconds. - - - Data Type: struct timeval - The `struct timeval' structure represents an elapsed time. It is - declared in `sys/time.h' and has the following members: - - `long int tv_sec' - This represents the number of whole seconds of elapsed time. - - `long int tv_usec' - This is the rest of the elapsed time (a fraction of a second), - represented as the number of microseconds. It is always less - than one million. - - - - Data Type: struct timespec - The `struct timespec' structure represents an elapsed time. It is - declared in `time.h' and has the following members: - - `long int tv_sec' - This represents the number of whole seconds of elapsed time. - - `long int tv_nsec' - This is the rest of the elapsed time (a fraction of a second), - represented as the number of nanoseconds. It is always less - than one billion. - - - It is often necessary to subtract two values of type -`struct timeval' or `struct timespec'. Here is the best way to do -this. It works even on some peculiar operating systems where the -`tv_sec' member has an unsigned type. - - /* Subtract the `struct timeval' values X and Y, - storing the result in RESULT. - Return 1 if the difference is negative, otherwise 0. */ - - int - timeval_subtract (result, x, y) - struct timeval *result, *x, *y; - { - /* Perform the carry for the later subtraction by updating Y. */ - if (x->tv_usec < y->tv_usec) { - int nsec = (y->tv_usec - x->tv_usec) / 1000000 + 1; - y->tv_usec -= 1000000 * nsec; - y->tv_sec += nsec; - } - if (x->tv_usec - y->tv_usec > 1000000) { - int nsec = (x->tv_usec - y->tv_usec) / 1000000; - y->tv_usec += 1000000 * nsec; - y->tv_sec -= nsec; - } - - /* Compute the time remaining to wait. - `tv_usec' is certainly positive. */ - result->tv_sec = x->tv_sec - y->tv_sec; - result->tv_usec = x->tv_usec - y->tv_usec; - - /* Return 1 if result is negative. */ - return x->tv_sec < y->tv_sec; - } - - Common functions that use `struct timeval' are `gettimeofday' and -`settimeofday'. - - There are no GNU C library functions specifically oriented toward -dealing with elapsed times, but the calendar time, processor time, and -alarm and sleeping functions have a lot to do with them. - - -File: libc.info, Node: Processor And CPU Time, Next: Calendar Time, Prev: Elapsed Time, Up: Date and Time - -Processor And CPU Time -====================== - - If you're trying to optimize your program or measure its efficiency, -it's very useful to know how much processor time it uses. For that, -calendar time and elapsed times are useless because a process may spend -time waiting for I/O or for other processes to use the CPU. However, -you can get the information with the functions in this section. - - CPU time (*note Time Basics::) is represented by the data type -`clock_t', which is a number of "clock ticks". It gives the total -amount of time a process has actively used a CPU since some arbitrary -event. On the GNU system, that event is the creation of the process. -While arbitrary in general, the event is always the same event for any -particular process, so you can always measure how much time on the CPU -a particular computation takes by examinining the process' CPU time -before and after the computation. - - In the GNU system, `clock_t' is equivalent to `long int' and -`CLOCKS_PER_SEC' is an integer value. But in other systems, both -`clock_t' and the macro `CLOCKS_PER_SEC' can be either integer or -floating-point types. Casting CPU time values to `double', as in the -example above, makes sure that operations such as arithmetic and -printing work properly and consistently no matter what the underlying -representation is. - - Note that the clock can wrap around. On a 32bit system with -`CLOCKS_PER_SEC' set to one million this function will return the same -value approximately every 72 minutes. - - For additional functions to examine a process' use of processor time, -and to control it, *Note Resource Usage And Limitation::. - -* Menu: - -* CPU Time:: The `clock' function. -* Processor Time:: The `times' function. - - -File: libc.info, Node: CPU Time, Next: Processor Time, Up: Processor And CPU Time - -CPU Time Inquiry ----------------- - - To get a process' CPU time, you can use the `clock' function. This -facility is declared in the header file `time.h'. - - In typical usage, you call the `clock' function at the beginning and -end of the interval you want to time, subtract the values, and then -divide by `CLOCKS_PER_SEC' (the number of clock ticks per second) to -get processor time, like this: - - #include - - clock_t start, end; - double cpu_time_used; - - start = clock(); - ... /* Do the work. */ - end = clock(); - cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC; - - Do not use a single CPU time as an amount of time; it doesn't work -that way. Either do a subtraction as shown above or query processor -time directly. *Note Processor Time::. - - Different computers and operating systems vary wildly in how they -keep track of CPU time. It's common for the internal processor clock -to have a resolution somewhere between a hundredth and millionth of a -second. - - - Macro: int CLOCKS_PER_SEC - The value of this macro is the number of clock ticks per second - measured by the `clock' function.

You should include the -header file `sys/times.h' to use this facility. - - - Data Type: struct tms - The `tms' structure is used to return information about process - times. It contains at least the following members: - - `clock_t tms_utime' - This is the total processor time the calling process has used - in executing the instructions of its program. - - `clock_t tms_stime' - This is the processor time the system has used on behalf of - the calling process. - - `clock_t tms_cutime' - This is the sum of the `tms_utime' values and the `tms_cutime' - values of all terminated child processes of the calling - process, whose status has been reported to the parent process - by `wait' or `waitpid'; see *Note Process Completion::. In - other words, it represents the total processor time used in - executing the instructions of all the terminated child - processes of the calling process, excluding child processes - which have not yet been reported by `wait' or `waitpid'. - - `clock_t tms_cstime' - This is similar to `tms_cutime', but represents the total - processor time system has used on behalf of all the - terminated child processes of the calling process. - - All of the times are given in numbers of clock ticks. Unlike CPU - time, these are the actual amounts of time; not relative to any - event. *Note Creating a Process::. - - - Function: clock_t times (struct tms *BUFFER) - The `times' function stores the processor time information for the - calling process in BUFFER. - - The return value is the calling process' CPU time (the same value - you get from `clock()'. `times' returns `(clock_t)(-1)' to - indicate failure. - - *Portability Note:* The `clock' function described in *Note CPU -Time:: is specified by the ISO C standard.

Like simple - time, this represents a calendar time as an elapsed time since a - base time, but instead of measuring in whole seconds, it uses a - `struct timeval' data type, which includes fractions of a second. - Use this time representation instead of simple time when you need - greater precision. - - * "Local time" or "broken-down time" (the `struct tm' data type) - represents a calendar time as a set of components specifying the - year, month, and so on in the Gregorian calendar, for a specific - time zone. This calendar time representation is usually used only - to communicate with people. - -* Menu: - -* Simple Calendar Time:: Facilities for manipulating calendar time. -* High-Resolution Calendar:: A time representation with greater precision. -* Broken-down Time:: Facilities for manipulating local time. -* High Accuracy Clock:: Maintaining a high accuracy system clock. -* Formatting Calendar Time:: Converting times to strings. -* Parsing Date and Time:: Convert textual time and date information back - into broken-down time values. -* TZ Variable:: How users specify the time zone. -* Time Zone Functions:: Functions to examine or specify the time zone. -* Time Functions Example:: An example program showing use of some of - the time functions. - - -File: libc.info, Node: Simple Calendar Time, Next: High-Resolution Calendar, Up: Calendar Time - -Simple Calendar Time --------------------- - - This section describes the `time_t' data type for representing -calendar time as simple time, and the functions which operate on simple -time objects. These facilities are declared in the header file -`time.h'. - - - Data Type: time_t - This is the data type used to represent simple time. Sometimes, - it also represents an elapsed time. When interpreted as a - calendar time value, it represents the number of seconds elapsed - since 00:00:00 on January 1, 1970, Coordinated Universal Time. - (This calendar time is sometimes referred to as the "epoch".) - POSIX requires that this count not include leap seconds, but on - some systems this count includes leap seconds if you set `TZ' to - certain values (*note TZ Variable::). - - Note that a simple time has no concept of local time zone. - Calendar Time T is the same instant in time regardless of where on - the globe the computer is. - - In the GNU C library, `time_t' is equivalent to `long int'. In - other systems, `time_t' might be either an integer or - floating-point type. - - The function `difftime' tells you the elapsed time between two -simple calendar times, which is not always as easy to compute as just -subtracting. *Note Elapsed Time::. - - - Function: time_t time (time_t *RESULT) - The `time' function returns the current calendar time as a value of - type `time_t'. If the argument RESULT is not a null pointer, the - calendar time value is also stored in `*RESULT'. If the current - calendar time is not available, the value `(time_t)(-1)' is - returned. - - - Function: int stime (time_t *NEWTIME) - `stime' sets the system clock, i.e. it tells the system that the - current calendar time is NEWTIME, where `newtime' is interpreted - as described in the above definition of `time_t'. - - `settimeofday' is a newer function which sets the system clock to - better than one second precision. `settimeofday' is generally a - better choice than `stime'. *Note High-Resolution Calendar::. - - Only the superuser can set the system clock. - - If the function succeeds, the return value is zero. Otherwise, it - is `-1' and `errno' is set accordingly: - - `EPERM' - The process is not superuser. - - -File: libc.info, Node: High-Resolution Calendar, Next: Broken-down Time, Prev: Simple Calendar Time, Up: Calendar Time - -High-Resolution Calendar ------------------------- - - The `time_t' data type used to represent simple times has a -resolution of only one second. Some applications need more precision. - - So, the GNU C library also contains functions which are capable of -representing calendar times to a higher resolution than one second. The -functions and the associated data types described in this section are -declared in `sys/time.h'. - - - Data Type: struct timezone - The `struct timezone' structure is used to hold minimal information - about the local time zone. It has the following members: - - `int tz_minuteswest' - This is the number of minutes west of UTC. - - `int tz_dsttime' - If nonzero, Daylight Saving Time applies during some part of - the year. - - The `struct timezone' type is obsolete and should never be used. - Instead, use the facilities described in *Note Time Zone - Functions::. - - - Function: int gettimeofday (struct timeval *TP, struct timezone *TZP) - The `gettimeofday' function returns the current calendar time as - the elapsed time since the epoch in the `struct timeval' structure - indicated by TP. (*note Elapsed Time:: for a description of - `struct timespec'). Information about the time zone is returned in - the structure pointed at TZP. If the TZP argument is a null - pointer, time zone information is ignored. - - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is defined for this function: - - `ENOSYS' - The operating system does not support getting time zone - information, and TZP is not a null pointer. The GNU - operating system does not support using `struct timezone' to - represent time zone information; that is an obsolete feature - of 4.3 BSD. Instead, use the facilities described in *Note - Time Zone Functions::. - - - Function: int settimeofday (const struct timeval *TP, const struct - timezone *TZP) - The `settimeofday' function sets the current calendar time in the - system clock according to the arguments. As for `gettimeofday', - the calendar time is represented as the elapsed time since the - epoch. As for `gettimeofday', time zone information is ignored if - TZP is a null pointer. - - You must be a privileged user in order to use `settimeofday'. - - Some kernels automatically set the system clock from some source - such as a hardware clock when they start up. Others, including - Linux, place the system clock in an "invalid" state (in which - attempts to read the clock fail). A call of `stime' removes the - system clock from an invalid state, and system startup scripts - typically run a program that calls `stime'. - - `settimeofday' causes a sudden jump forwards or backwards, which - can cause a variety of problems in a system. Use `adjtime' (below) - to make a smooth transition from one time to another by temporarily - speeding up or slowing down the clock. - - With a Linux kernel, `adjtimex' does the same thing and can also - make permanent changes to the speed of the system clock so it - doesn't need to be corrected as often. - - The return value is `0' on success and `-1' on failure. The - following `errno' error conditions are defined for this function: - - `EPERM' - This process cannot set the clock because it is not - privileged. - - `ENOSYS' - The operating system does not support setting time zone - information, and TZP is not a null pointer. - - - Function: int adjtime (const struct timeval *DELTA, struct timeval - *OLDDELTA) - This function speeds up or slows down the system clock in order to - make a gradual adjustment. This ensures that the calendar time - reported by the system clock is always monotonically increasing, - which might not happen if you simply set the clock. - - The DELTA argument specifies a relative adjustment to be made to - the clock time. If negative, the system clock is slowed down for a - while until it has lost this much elapsed time. If positive, the - system clock is speeded up for a while. - - If the OLDDELTA argument is not a null pointer, the `adjtime' - function returns information about any previous time adjustment - that has not yet completed. - - This function is typically used to synchronize the clocks of - computers in a local network. You must be a privileged user to - use it. - - With a Linux kernel, you can use the `adjtimex' function to - permanently change the clock speed. - - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is defined for this function: - - `EPERM' - You do not have privilege to set the time. - - *Portability Note:* The `gettimeofday', `settimeofday', and -`adjtime' functions are derived from BSD. - - Symbols for the following function are declared in `sys/timex.h'. - - - Function: int adjtimex (struct timex *TIMEX) - `adjtimex' is functionally identical to `ntp_adjtime'. *Note High - Accuracy Clock::. - - This function is present only with a Linux kernel. - - - -File: libc.info, Node: Broken-down Time, Next: High Accuracy Clock, Prev: High-Resolution Calendar, Up: Calendar Time - -Broken-down Time ----------------- - - Calendar time is represented by the usual GNU C library functions as -an elapsed time since a fixed base calendar time. This is convenient -for computation, but has no relation to the way people normally think of -calendar time. By contrast, "broken-down time" is a binary -representation of calendar time separated into year, month, day, and so -on. Broken-down time values are not useful for calculations, but they -are useful for printing human readable time information. - - A broken-down time value is always relative to a choice of time -zone, and it also indicates which time zone that is. - - The symbols in this section are declared in the header file `time.h'. - - - Data Type: struct tm - This is the data type used to represent a broken-down time. The - structure contains at least the following members, which can - appear in any order. - - `int tm_sec' - This is the number of full seconds since the top of the - minute (normally in the range `0' through `59', but the - actual upper limit is `60', to allow for leap seconds if leap - second support is available). - - `int tm_min' - This is the number of full minutes since the top of the hour - (in the range `0' through `59'). - - `int tm_hour' - This is the number of full hours past midnight (in the range - `0' through `23'). - - `int tm_mday' - This is the ordinal day of the month (in the range `1' - through `31'). Watch out for this one! As the only ordinal - number in the structure, it is inconsistent with the rest of - the structure. - - `int tm_mon' - This is the number of full calendar months since the - beginning of the year (in the range `0' through `11'). Watch - out for this one! People usually use ordinal numbers for - month-of-year (where January = 1). - - `int tm_year' - This is the number of full calendar years since 1900. - - `int tm_wday' - This is the number of full days since Sunday (in the range - `0' through `6'). - - `int tm_yday' - This is the number of full days since the beginning of the - year (in the range `0' through `365'). - - `int tm_isdst' - This is a flag that indicates whether Daylight Saving Time is - (or was, or will be) in effect at the time described. The - value is positive if Daylight Saving Time is in effect, zero - if it is not, and negative if the information is not - available. - - `long int tm_gmtoff' - This field describes the time zone that was used to compute - this broken-down time value, including any adjustment for - daylight saving; it is the number of seconds that you must - add to UTC to get local time. You can also think of this as - the number of seconds east of UTC. For example, for U.S. - Eastern Standard Time, the value is `-5*60*60'. The - `tm_gmtoff' field is derived from BSD and is a GNU library - extension; it is not visible in a strict ISO C environment. - - `const char *tm_zone' - This field is the name for the time zone that was used to - compute this broken-down time value. Like `tm_gmtoff', this - field is a BSD and GNU extension, and is not visible in a - strict ISO C environment. - - - Function: struct tm * localtime (const time_t *TIME) - The `localtime' function converts the simple time pointed to by - TIME to broken-down time representation, expressed relative to the - user's specified time zone. - - The return value is a pointer to a static broken-down time - structure, which might be overwritten by subsequent calls to - `ctime', `gmtime', or `localtime'. (But no other library function - overwrites the contents of this object.) - - The return value is the null pointer if TIME cannot be represented - as a broken-down time; typically this is because the year cannot - fit into an `int'. - - Calling `localtime' has one other effect: it sets the variable - `tzname' with information about the current time zone. *Note Time - Zone Functions::. - - Using the `localtime' function is a big problem in multi-threaded -programs. The result is returned in a static buffer and this is used in -all threads. POSIX.1c introduced a variant of this function. - - - Function: struct tm * localtime_r (const time_t *TIME, struct tm - *RESULTP) - The `localtime_r' function works just like the `localtime' - function. It takes a pointer to a variable containing a simple - time and converts it to the broken-down time format. - - But the result is not placed in a static buffer. Instead it is - placed in the object of type `struct tm' to which the parameter - RESULTP points. - - If the conversion is successful the function returns a pointer to - the object the result was written into, i.e., it returns RESULTP. - - - Function: struct tm * gmtime (const time_t *TIME) - This function is similar to `localtime', except that the - broken-down time is expressed as Coordinated Universal Time (UTC) - (formerly called Greenwich Mean Time (GMT)) rather than relative - to a local time zone. - - - As for the `localtime' function we have the problem that the result -is placed in a static variable. POSIX.1c also provides a replacement -for `gmtime'. - - - Function: struct tm * gmtime_r (const time_t *TIME, struct tm - *RESULTP) - This function is similar to `localtime_r', except that it converts - just like `gmtime' the given time as Coordinated Universal Time. - - If the conversion is successful the function returns a pointer to - the object the result was written into, i.e., it returns RESULTP. - - - Function: time_t mktime (struct tm *BROKENTIME) - The `mktime' function is used to convert a broken-down time - structure to a simple time representation. It also "normalizes" - the contents of the broken-down time structure, by filling in the - day of week and day of year based on the other date and time - components. - - The `mktime' function ignores the specified contents of the - `tm_wday' and `tm_yday' members of the broken-down time structure. - It uses the values of the other components to determine the - calendar time; it's permissible for these components to have - unnormalized values outside their normal ranges. The last thing - that `mktime' does is adjust the components of the BROKENTIME - structure (including the `tm_wday' and `tm_yday'). - - If the specified broken-down time cannot be represented as a - simple time, `mktime' returns a value of `(time_t)(-1)' and does - not modify the contents of BROKENTIME. - - Calling `mktime' also sets the variable `tzname' with information - about the current time zone. *Note Time Zone Functions::. - - - Function: time_t timelocal (struct tm *BROKENTIME) - `timelocal' is functionally identical to `mktime', but more - mnemonically named. Note that it is the inverse of the `localtime' - function. - - *Portability note:* `mktime' is essentially universally - available. `timelocal' is rather rare. - - - - Function: time_t timegm (struct tm *BROKENTIME) - `timegm' is functionally identical to `mktime' except it always - takes the input values to be Coordinated Universal Time (UTC) - regardless of any local time zone setting. - - Note that `timegm' is the inverse of `gmtime'. - - *Portability note:* `mktime' is essentially universally - available. `timegm' is rather rare. For the most portable - conversion from a UTC broken-down time to a simple time, set the - `TZ' environment variable to UTC, call `mktime', then set `TZ' - back. - - - -File: libc.info, Node: High Accuracy Clock, Next: Formatting Calendar Time, Prev: Broken-down Time, Up: Calendar Time - -High Accuracy Clock -------------------- - - The `ntp_gettime' and `ntp_adjtime' functions provide an interface -to monitor and manipulate the system clock to maintain high accuracy -time. For example, you can fine tune the speed of the clock or -synchronize it with another time source. - - A typical use of these functions is by a server implementing the -Network Time Protocol to synchronize the clocks of multiple systems and -high precision clocks. - - These functions are declared in `sys/timex.h'. - - - Data Type: struct ntptimeval - This structure is used for information about the system clock. It - contains the following members: - `struct timeval time' - This is the current calendar time, expressed as the elapsed - time since the epoch. The `struct timeval' data type is - described in *Note Elapsed Time::. - - `long int maxerror' - This is the maximum error, measured in microseconds. Unless - updated via `ntp_adjtime' periodically, this value will reach - some platform-specific maximum value. - - `long int esterror' - This is the estimated error, measured in microseconds. This - value can be set by `ntp_adjtime' to indicate the estimated - offset of the system clock from the true calendar time. - - - Function: int ntp_gettime (struct ntptimeval *TPTR) - The `ntp_gettime' function sets the structure pointed to by TPTR - to current values. The elements of the structure afterwards - contain the values the timer implementation in the kernel assumes. - They might or might not be correct. If they are not a - `ntp_adjtime' call is necessary. - - The return value is `0' on success and other values on failure. - The following `errno' error conditions are defined for this - function: - - `TIME_ERROR' - The precision clock model is not properly set up at the - moment, thus the clock must be considered unsynchronized, and - the values should be treated with care. - - - Data Type: struct timex - This structure is used to control and monitor the system clock. It - contains the following members: - `unsigned int modes' - This variable controls whether and which values are set. - Several symbolic constants have to be combined with _binary - or_ to specify the effective mode. These constants start - with `MOD_'. - - `long int offset' - This value indicates the current offset of the system clock - from the true calendar time. The value is given in - microseconds. If bit `MOD_OFFSET' is set in `modes', the - offset (and possibly other dependent values) can be set. The - offset's absolute value must not exceed `MAXPHASE'. - - `long int frequency' - This value indicates the difference in frequency between the - true calendar time and the system clock. The value is - expressed as scaled PPM (parts per million, 0.0001%). The - scaling is `1 << SHIFT_USEC'. The value can be set with bit - `MOD_FREQUENCY', but the absolute value must not exceed - `MAXFREQ'. - - `long int maxerror' - This is the maximum error, measured in microseconds. A new - value can be set using bit `MOD_MAXERROR'. Unless updated via - `ntp_adjtime' periodically, this value will increase steadily - and reach some platform-specific maximum value. - - `long int esterror' - This is the estimated error, measured in microseconds. This - value can be set using bit `MOD_ESTERROR'. - - `int status' - This variable reflects the various states of the clock - machinery. There are symbolic constants for the significant - bits, starting with `STA_'. Some of these flags can be - updated using the `MOD_STATUS' bit. - - `long int constant' - This value represents the bandwidth or stiffness of the PLL - (phase locked loop) implemented in the kernel.

A - clock tick is a periodic timer interrupt on which the system - clock is based. - - `long int ppsfreq' - This is the first of a few optional variables that are - present only if the system clock can use a PPS (pulse per - second) signal to discipline the system clock. The value is - expressed in scaled PPM and it denotes the difference in - frequency between the system clock and the PPS signal. - - `long int jitter' - This value expresses a median filtered average of the PPS - signal's dispersion in microseconds. - - `int shift' - This value is a binary exponent for the duration of the PPS - calibration interval, ranging from `PPS_SHIFT' to - `PPS_SHIFTMAX'. - - `long int stabil' - This value represents the median filtered dispersion of the - PPS frequency in scaled PPM. - - `long int jitcnt' - This counter represents the number of pulses where the jitter - exceeded the allowed maximum `MAXTIME'. - - `long int calcnt' - This counter reflects the number of successful calibration - intervals. - - `long int errcnt' - This counter represents the number of calibration errors - (caused by large offsets or jitter). - - `long int stbcnt' - This counter denotes the number of of calibrations where the - stability exceeded the threshold. - - - Function: int ntp_adjtime (struct timex *TPTR) - The `ntp_adjtime' function sets the structure specified by TPTR to - current values. - - In addition, `ntp_adjtime' updates some settings to match what you - pass to it in *TPTR.

In a Japanese locale, for example, - `%Ex' might yield a date format based on the Japanese - Emperors' reigns. - - `O' - Use the locale's alternate numeric symbols for numbers. This - modifier applies only to numeric format specifiers. - - If the format supports the modifier but no alternate representation - is available, it is ignored. - - The conversion specifier ends with a format specifier taken from - the following list. The whole `%' sequence is replaced in the - output string as follows: - - `%a' - The abbreviated weekday name according to the current locale. - - `%A' - The full weekday name according to the current locale. - - `%b' - The abbreviated month name according to the current locale. - - `%B' - The full month name according to the current locale. - - `%c' - The preferred calendar time representation for the current - locale. - - `%C' - The century of the year. This is equivalent to the greatest - integer not greater than the year divided by 100. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%d' - The day of the month as a decimal number (range `01' through - `31'). - - `%D' - The date using the format `%m/%d/%y'. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%e' - The day of the month like with `%d', but padded with blank - (range ` 1' through `31'). - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%F' - The date using the format `%Y-%m-%d'. This is the form - specified in the ISO 8601 standard and is the preferred form - for all uses. - - This format was first standardized by ISO C99 and by - POSIX.1-2001. - - `%g' - The year corresponding to the ISO week number, but without - the century (range `00' through `99'). This has the same - format and value as `%y', except that if the ISO week number - (see `%V') belongs to the previous or next year, that year is - used instead. - - This format was first standardized by ISO C99 and by - POSIX.1-2001. - - `%G' - The year corresponding to the ISO week number. This has the - same format and value as `%Y', except that if the ISO week - number (see `%V') belongs to the previous or next year, that - year is used instead. - - This format was first standardized by ISO C99 and by - POSIX.1-2001 but was previously available as a GNU extension. - - `%h' - The abbreviated month name according to the current locale. - The action is the same as for `%b'. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%H' - The hour as a decimal number, using a 24-hour clock (range - `00' through `23'). - - `%I' - The hour as a decimal number, using a 12-hour clock (range - `01' through `12'). - - `%j' - The day of the year as a decimal number (range `001' through - `366'). - - `%k' - The hour as a decimal number, using a 24-hour clock like - `%H', but padded with blank (range ` 0' through `23'). - - This format is a GNU extension. - - `%l' - The hour as a decimal number, using a 12-hour clock like - `%I', but padded with blank (range ` 1' through `12'). - - This format is a GNU extension. - - `%m' - The month as a decimal number (range `01' through `12'). - - `%M' - The minute as a decimal number (range `00' through `59'). - - `%n' - A single `\n' (newline) character. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%p' - Either `AM' or `PM', according to the given time value; or the - corresponding strings for the current locale. Noon is - treated as `PM' and midnight as `AM'. In most locales - `AM'/`PM' format is not supported, in such cases `"%p"' - yields an empty string. - - `%P' - Either `am' or `pm', according to the given time value; or the - corresponding strings for the current locale, printed in - lowercase characters. Noon is treated as `pm' and midnight - as `am'. In most locales `AM'/`PM' format is not supported, - in such cases `"%P"' yields an empty string. - - This format is a GNU extension. - - `%r' - The complete calendar time using the AM/PM format of the - current locale. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. In the POSIX locale, this format is equivalent to - `%I:%M:%S %p'. - - `%R' - The hour and minute in decimal numbers using the format - `%H:%M'. - - This format was first standardized by ISO C99 and by - POSIX.1-2001 but was previously available as a GNU extension. - - `%s' - The number of seconds since the epoch, i.e., since 1970-01-01 - 00:00:00 UTC. Leap seconds are not counted unless leap - second support is available. - - This format is a GNU extension. - - `%S' - The seconds as a decimal number (range `00' through `60'). - - `%t' - A single `\t' (tabulator) character. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%T' - The time of day using decimal numbers using the format - `%H:%M:%S'. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%u' - The day of the week as a decimal number (range `1' through - `7'), Monday being `1'. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%U' - The week number of the current year as a decimal number - (range `00' through `53'), starting with the first Sunday as - the first day of the first week. Days preceding the first - Sunday in the year are considered to be in week `00'. - - `%V' - The ISO 8601:1988 week number as a decimal number (range `01' - through `53'). ISO weeks start with Monday and end with - Sunday. Week `01' of a year is the first week which has the - majority of its days in that year; this is equivalent to the - week containing the year's first Thursday, and it is also - equivalent to the week containing January 4. Week `01' of a - year can contain days from the previous year. The week - before week `01' of a year is the last week (`52' or `53') of - the previous year even if it contains days from the new year. - - This format was first standardized by POSIX.2-1992 and by - ISO C99. - - `%w' - The day of the week as a decimal number (range `0' through - `6'), Sunday being `0'. - - `%W' - The week number of the current year as a decimal number - (range `00' through `53'), starting with the first Monday as - the first day of the first week. All days preceding the - first Monday in the year are considered to be in week `00'. - - `%x' - The preferred date representation for the current locale. - - `%X' - The preferred time of day representation for the current - locale. - - `%y' - The year without a century as a decimal number (range `00' - through `99'). This is equivalent to the year modulo 100. - - `%Y' - The year as a decimal number, using the Gregorian calendar. - Years before the year `1' are numbered `0', `-1', and so on. - - `%z' - RFC 822/ISO 8601:1988 style numeric time zone (e.g., `-0600' - or `+0100'), or nothing if no time zone is determinable. - - This format was first standardized by ISO C99 and by - POSIX.1-2001 but was previously available as a GNU extension. - - In the POSIX locale, a full RFC 822 timestamp is generated by - the format `"%a, %d %b %Y %H:%M:%S %z"' (or the equivalent - `"%a, %d %b %Y %T %z"'). - - `%Z' - The time zone abbreviation (empty if the time zone can't be - determined). - - `%%' - A literal `%' character. - - The SIZE parameter can be used to specify the maximum number of - characters to be stored in the array S, including the terminating - null character. If the formatted time requires more than SIZE - characters, `strftime' returns zero and the contents of the array - S are undefined. Otherwise the return value indicates the number - of characters placed in the array S, not including the terminating - null character. - - _Warning:_ This convention for the return value which is prescribed - in ISO C can lead to problems in some situations. For certain - format strings and certain locales the output really can be the - empty string and this cannot be discovered by testing the return - value only. E.g., in most locales the AM/PM time format is not - supported (most of the world uses the 24 hour time - representation). In such locales `"%p"' will return the empty - string, i.e., the return value is zero. To detect situations like - this something similar to the following code should be used: - - buf[0] = '\1'; - len = strftime (buf, bufsize, format, tp); - if (len == 0 && buf[0] != '\0') - { - /* Something went wrong in the strftime call. */ - ... - } - - If S is a null pointer, `strftime' does not actually write - anything, but instead returns the number of characters it would - have written. - - According to POSIX.1 every call to `strftime' implies a call to - `tzset'. So the contents of the environment variable `TZ' is - examined before any output is produced. - - For an example of `strftime', see *Note Time Functions Example::. - - - Function: size_t wcsftime (wchar_t *S, size_t SIZE, const wchar_t - *TEMPLATE, const struct tm *BROKENTIME) - The `wcsftime' function is equivalent to the `strftime' function - with the difference that it operates on wide character strings. - The buffer where the result is stored, pointed to by S, must be an - array of wide characters. The parameter SIZE which specifies the - size of the output buffer gives the number of wide character, not - the number of bytes. - - Also the format string TEMPLATE is a wide character string. Since - all characters needed to specify the format string are in the basic - character set it is portably possible to write format strings in - the C source code using the `L"..."' notation. The parameter - BROKENTIME has the same meaning as in the `strftime' call. - - The `wcsftime' function supports the same flags, modifiers, and - format specifiers as the `strftime' function. - - The return value of `wcsftime' is the number of wide characters - stored in `s'. When more characters would have to be written than - can be placed in the buffer S the return value is zero, with the - same problems indicated in the `strftime' documentation. - - -File: libc.info, Node: Parsing Date and Time, Next: TZ Variable, Prev: Formatting Calendar Time, Up: Calendar Time - -Convert textual time and date information back ----------------------------------------------- - - The ISO C standard does not specify any functions which can convert -the output of the `strftime' function back into a binary format. This -led to a variety of more-or-less successful implementations with -different interfaces over the years. Then the Unix standard was -extended by the addition of two functions: `strptime' and `getdate'. -Both have strange interfaces but at least they are widely available. - -* Menu: - -* Low-Level Time String Parsing:: Interpret string according to given format. -* General Time String Parsing:: User-friendly function to parse data and - time strings. - - -File: libc.info, Node: Low-Level Time String Parsing, Next: General Time String Parsing, Up: Parsing Date and Time - -Interpret string according to given format -.......................................... - - he first function is rather low-level. It is nevertheless frequently -used in software since it is better known. Its interface and -implementation are heavily influenced by the `getdate' function, which -is defined and implemented in terms of calls to `strptime'. - - - Function: char * strptime (const char *S, const char *FMT, struct tm - *TP) - The `strptime' function parses the input string S according to the - format string FMT and stores its results in the structure TP. - - The input string could be generated by a `strftime' call or - obtained any other way. It does not need to be in a - human-recognizable format; e.g. a date passed as `"02:1999:9"' is - acceptable, even though it is ambiguous without context. As long - as the format string FMT matches the input string the function - will succeed. - - The user has to make sure, though, that the input can be parsed in - a unambiguous way. The string `"1999112"' can be parsed using the - format `"%Y%m%d"' as 1999-1-12, 1999-11-2, or even 19991-1-2. It - is necessary to add appropriate separators to reliably get results. - - The format string consists of the same components as the format - string of the `strftime' function. The only difference is that - the flags `_', `-', `0', and `^' are not allowed. Several of the - distinct formats of `strftime' do the same work in `strptime' - since differences like case of the input do not matter. For - reasons of symmetry all formats are supported, though. - - The modifiers `E' and `O' are also allowed everywhere the - `strftime' function allows them. - - The formats are: - - `%a' - `%A' - The weekday name according to the current locale, in - abbreviated form or the full name. - - `%b' - `%B' - `%h' - The month name according to the current locale, in - abbreviated form or the full name. - - `%c' - The date and time representation for the current locale. - - `%Ec' - Like `%c' but the locale's alternative date and time format - is used. - - `%C' - The century of the year. - - It makes sense to use this format only if the format string - also contains the `%y' format. - - `%EC' - The locale's representation of the period. - - Unlike `%C' it sometimes makes sense to use this format since - some cultures represent years relative to the beginning of - eras instead of using the Gregorian years. - - `%d' - - `%e' - The day of the month as a decimal number (range `1' through - `31'). Leading zeroes are permitted but not required. - - `%Od' - `%Oe' - Same as `%d' but using the locale's alternative numeric - symbols. - - Leading zeroes are permitted but not required. - - `%D' - Equivalent to `%m/%d/%y'. - - `%F' - Equivalent to `%Y-%m-%d', which is the ISO 8601 date format. - - This is a GNU extension following an ISO C99 extension to - `strftime'. - - `%g' - The year corresponding to the ISO week number, but without - the century (range `00' through `99'). - - _Note:_ Currently, this is not fully implemented.

Leap seconds are not counted unless leap - second support is available. - - `%s' is a GNU extension following a GNU extension to - `strftime'. - - `%S' - The seconds as a decimal number (range `0' through `60'). - - Leading zeroes are permitted but not required. - - *Note:* The Unix specification says the upper bound on this - value is `61', a result of a decision to allow double leap - seconds. You will not see the value `61' because no minute - has more than one leap second, but the myth persists. - - `%OS' - Same as `%S' but using the locale's alternative numeric - symbols. - - `%T' - Equivalent to the use of `%H:%M:%S' in this place. - - `%u' - The day of the week as a decimal number (range `1' through - `7'), Monday being `1'. - - Leading zeroes are permitted but not required. - - _Note:_ Currently, this is not fully implemented. The format - is recognized, input is consumed but no field in TM is set. - - `%U' - The week number of the current year as a decimal number - (range `0' through `53'). - - Leading zeroes are permitted but not required. - - `%OU' - Same as `%U' but using the locale's alternative numeric - symbols. - - `%V' - The ISO 8601:1988 week number as a decimal number (range `1' - through `53'). - - Leading zeroes are permitted but not required. - - _Note:_ Currently, this is not fully implemented. The format - is recognized, input is consumed but no field in TM is set. - - `%w' - The day of the week as a decimal number (range `0' through - `6'), Sunday being `0'. - - Leading zeroes are permitted but not required. - - _Note:_ Currently, this is not fully implemented. The format - is recognized, input is consumed but no field in TM is set. - - `%Ow' - Same as `%w' but using the locale's alternative numeric - symbols. - - `%W' - The week number of the current year as a decimal number - (range `0' through `53'). - - Leading zeroes are permitted but not required. - - _Note:_ Currently, this is not fully implemented. The format - is recognized, input is consumed but no field in TM is set. - - `%OW' - Same as `%W' but using the locale's alternative numeric - symbols. - - `%x' - The date using the locale's date format. - - `%Ex' - Like `%x' but the locale's alternative data representation is - used. - - `%X' - The time using the locale's time format. - - `%EX' - Like `%X' but the locale's alternative time representation is - used. - - `%y' - The year without a century as a decimal number (range `0' - through `99'). - - Leading zeroes are permitted but not required. - - Note that it is questionable to use this format without the - `%C' format. The `strptime' function does regard input - values in the range 68 to 99 as the years 1969 to 1999 and - the values 0 to 68 as the years 2000 to 2068. But maybe this - heuristic fails for some input data. - - Therefore it is best to avoid `%y' completely and use `%Y' - instead. - - `%Ey' - The offset from `%EC' in the locale's alternative - representation. - - `%Oy' - The offset of the year (from `%C') using the locale's - alternative numeric symbols. - - `%Y' - The year as a decimal number, using the Gregorian calendar. - - `%EY' - The full alternative year representation. - - `%z' - The offset from GMT in ISO 8601/RFC822 format. - - `%Z' - The timezone name. - - _Note:_ Currently, this is not fully implemented. The format - is recognized, input is consumed but no field in TM is set. - - `%%' - A literal `%' character. - - All other characters in the format string must have a matching - character in the input string. Exceptions are white spaces in the - input string which can match zero or more whitespace characters in - the format string. - - *Portability Note:* The XPG standard advises applications to use - at least one whitespace character (as specified by `isspace') or - other non-alphanumeric characters between any two conversion - specifications. The GNU C Library does not have this limitation - but other libraries might have trouble parsing formats like - `"%d%m%Y%H%M%S"'. - - The `strptime' function processes the input string from right to - left. Each of the three possible input elements (white space, - literal, or format) are handled one after the other. If the input - cannot be matched to the format string the function stops. The - remainder of the format and input strings are not processed. - - The function returns a pointer to the first character it was - unable to process. If the input string contains more characters - than required by the format string the return value points right - after the last consumed input character. If the whole input - string is consumed the return value points to the `NULL' byte at - the end of the string. If an error occurs, i.e. `strptime' fails - to match all of the format string, the function returns `NULL'. - - The specification of the function in the XPG standard is rather -vague, leaving out a few important pieces of information. Most -importantly, it does not specify what happens to those elements of TM -which are not directly initialized by the different formats. The -implementations on different Unix systems vary here. - - The GNU libc implementation does not touch those fields which are not -directly initialized. Exceptions are the `tm_wday' and `tm_yday' -elements, which are recomputed if any of the year, month, or date -elements changed. This has two implications: - - * Before calling the `strptime' function for a new input string, you - should prepare the TM structure you pass. Normally this will mean - initializing all values are to zero. Alternatively, you can set - all fields to values like `INT_MAX', allowing you to determine - which elements were set by the function call. Zero does not work - here since it is a valid value for many of the fields. - - Careful initialization is necessary if you want to find out - whether a certain field in TM was initialized by the function call. - - * You can construct a `struct tm' value with several consecutive - `strptime' calls. A useful application of this is e.g. the parsing - of two separate strings, one containing date information and the - other time information. By parsing one after the other without - clearing the structure in-between, you can construct a complete - broken-down time. - - The following example shows a function which parses a string which is -contains the date information in either US style or ISO 8601 form: - - const char * - parse_date (const char *input, struct tm *tm) - { - const char *cp; - - /* First clear the result structure. */ - memset (tm, '\0', sizeof (*tm)); - - /* Try the ISO format first. */ - cp = strptime (input, "%F", tm); - if (cp == NULL) - { - /* Does not match. Try the US form. */ - cp = strptime (input, "%D", tm); - } - - return cp; - } - - -File: libc.info, Node: General Time String Parsing, Prev: Low-Level Time String Parsing, Up: Parsing Date and Time - -A More User-friendly Way to Parse Times and Dates -................................................. - - The Unix standard defines another function for parsing date strings. -The interface is weird, but if the function happens to suit your -application it is just fine. It is problematic to use this function in -multi-threaded programs or libraries, since it returns a pointer to a -static variable, and uses a global variable and global state (an -environment variable). - - - Variable: getdate_err - This variable of type `int' contains the error code of the last - unsuccessful call to `getdate'. Defined values are: - - 1 - The environment variable `DATEMSK' is not defined or null. - - 2 - The template file denoted by the `DATEMSK' environment - variable cannot be opened. - - 3 - Information about the template file cannot retrieved. - - 4 - The template file is not a regular file. - - 5 - An I/O error occurred while reading the template file. - - 6 - Not enough memory available to execute the function. - - 7 - The template file contains no matching template. - - 8 - The input date is invalid, but would match a template - otherwise. This includes dates like February 31st, and dates - which cannot be represented in a `time_t' variable. - - - Function: struct tm * getdate (const char *STRING) - The interface to `getdate' is the simplest possible for a function - to parse a string and return the value. STRING is the input - string and the result is returned in a statically-allocated - variable. - - The details about how the string is processed are hidden from the - user. In fact, they can be outside the control of the program. - Which formats are recognized is controlled by the file named by - the environment variable `DATEMSK'. This file should contain - lines of valid format strings which could be passed to `strptime'. - - The `getdate' function reads these format strings one after the - other and tries to match the input string. The first line which - completely matches the input string is used. - - Elements not initialized through the format string retain the - values present at the time of the `getdate' function call. - - The formats recognized by `getdate' are the same as for - `strptime'. See above for an explanation. There are only a few - extensions to the `strptime' behavior: - - * If the `%Z' format is given the broken-down time is based on - the current time of the timezone matched, not of the current - timezone of the runtime environment. - - _Note_: This is not implemented (currently). The problem is - that timezone names are not unique. If a fixed timezone is - assumed for a given string (say `EST' meaning US East Coast - time), then uses for countries other than the USA will fail. - So far we have found no good solution to this. - - * If only the weekday is specified the selected day depends on - the current date. If the current weekday is greater or equal - to the `tm_wday' value the current week's day is chosen, - otherwise the day next week is chosen. - - * A similar heuristic is used when only the month is given and - not the year. If the month is greater than or equal to the - current month, then the current year is used. Otherwise it - wraps to next year. The first day of the month is assumed if - one is not explicitly specified. - - * The current hour, minute, and second are used if the - appropriate value is not set through the format. - - * If no date is given tomorrow's date is used if the time is - smaller than the current time. Otherwise today's date is - taken. - - It should be noted that the format in the template file need not - only contain format elements. The following is a list of possible - format strings (taken from the Unix standard): - - %m - %A %B %d, %Y %H:%M:%S - %A - %B - %m/%d/%y %I %p - %d,%m,%Y %H:%M - at %A the %dst of %B in %Y - run job at %I %p,%B %dnd - %A den %d. %B %Y %H.%M Uhr - - As you can see, the template list can contain very specific - strings like `run job at %I %p,%B %dnd'. Using the above list of - templates and assuming the current time is Mon Sep 22 12:19:47 EDT - 1986 we can obtain the following results for the given input. - - Input Match Result - Mon %a Mon Sep 22 12:19:47 EDT 1986 - Sun %a Sun Sep 28 12:19:47 EDT 1986 - Fri %a Fri Sep 26 12:19:47 EDT 1986 - September %B Mon Sep 1 12:19:47 EDT 1986 - January %B Thu Jan 1 12:19:47 EST 1987 - December %B Mon Dec 1 12:19:47 EST 1986 - Sep Mon %b %a Mon Sep 1 12:19:47 EDT 1986 - Jan Fri %b %a Fri Jan 2 12:19:47 EST 1987 - Dec Mon %b %a Mon Dec 1 12:19:47 EST 1986 - Jan Wed 1989 %b %a %Y Wed Jan 4 12:19:47 EST 1989 - Fri 9 %a %H Fri Sep 26 09:00:00 EDT 1986 - Feb 10:30 %b %H:%S Sun Feb 1 10:00:30 EST 1987 - 10:30 %H:%M Tue Sep 23 10:30:00 EDT 1986 - 13:30 %H:%M Mon Sep 22 13:30:00 EDT 1986 - - The return value of the function is a pointer to a static variable - of type `struct tm', or a null pointer if an error occurred. The - result is only valid until the next `getdate' call, making this - function unusable in multi-threaded applications. - - The `errno' variable is _not_ changed. Error conditions are - stored in the global variable `getdate_err'. See the description - above for a list of the possible error values. - - _Warning:_ The `getdate' function should _never_ be used in - SUID-programs. The reason is obvious: using the `DATEMSK' - environment variable you can get the function to open any - arbitrary file and chances are high that with some bogus input - (such as a binary file) the program will crash. - - - Function: int getdate_r (const char *STRING, struct tm *TP) - The `getdate_r' function is the reentrant counterpart of - `getdate'. It does not use the global variable `getdate_err' to - signal an error, but instead returns an error code. The same error - codes as described in the `getdate_err' documentation above are - used, with 0 meaning success. - - Moreover, `getdate_r' stores the broken-down time in the variable - of type `struct tm' pointed to by the second argument, rather than - in a static variable. - - This function is not defined in the Unix standard. Nevertheless - it is available on some other Unix systems as well. - - The warning against using `getdate' in SUID-programs applies to - `getdate_r' as well. - - -File: libc.info, Node: TZ Variable, Next: Time Zone Functions, Prev: Parsing Date and Time, Up: Calendar Time - -Specifying the Time Zone with `TZ' ----------------------------------- - - In POSIX systems, a user can specify the time zone by means of the -`TZ' environment variable. For information about how to set -environment variables, see *Note Environment Variables::. The functions -for accessing the time zone are declared in `time.h'. - - You should not normally need to set `TZ'. If the system is -configured properly, the default time zone will be correct. You might -set `TZ' if you are using a computer over a network from a different -time zone, and would like times reported to you in the time zone local -to you, rather than what is local to the computer. - - In POSIX.1 systems the value of the `TZ' variable can be in one of -three formats. With the GNU C library, the most common format is the -last one, which can specify a selection from a large database of time -zone information for many regions of the world. The first two formats -are used to describe the time zone information directly, which is both -more cumbersome and less precise. But the POSIX.1 standard only -specifies the details of the first two formats, so it is good to be -familiar with them in case you come across a POSIX.1 system that doesn't -support a time zone information database. - - The first format is used when there is no Daylight Saving Time (or -summer time) in the local time zone: - - STD OFFSET - - The STD string specifies the name of the time zone. It must be -three or more characters long and must not contain a leading colon, -embedded digits, commas, nor plus and minus signs. There is no space -character separating the time zone name from the OFFSET, so these -restrictions are necessary to parse the specification correctly. - - The OFFSET specifies the time value you must add to the local time -to get a Coordinated Universal Time value. It has syntax like -[`+'|`-']HH[`:'MM[`:'SS]]. This is positive if the local time zone is -west of the Prime Meridian and negative if it is east. The hour must -be between `0' and `23', and the minute and seconds between `0' and -`59'. - - For example, here is how we would specify Eastern Standard Time, but -without any Daylight Saving Time alternative: - - EST+5 - - The second format is used when there is Daylight Saving Time: - - STD OFFSET DST [OFFSET]`,'START[`/'TIME]`,'END[`/'TIME] - - The initial STD and OFFSET specify the standard time zone, as -described above. The DST string and OFFSET specify the name and offset -for the corresponding Daylight Saving Time zone; if the OFFSET is -omitted, it defaults to one hour ahead of standard time. - - The remainder of the specification describes when Daylight Saving -Time is in effect. The START field is when Daylight Saving Time goes -into effect and the END field is when the change is made back to -standard time. The following formats are recognized for these fields: - -`JN' - This specifies the Julian day, with N between `1' and `365'. - February 29 is never counted, even in leap years. - -`N' - This specifies the Julian day, with N between `0' and `365'. - February 29 is counted in leap years. - -`MM.W.D' - This specifies day D of week W of month M. The day D must be - between `0' (Sunday) and `6'. The week W must be between `1' and - `5'; week `1' is the first week in which day D occurs, and week - `5' specifies the _last_ D day in the month. The month M should be - between `1' and `12'. - - The TIME fields specify when, in the local time currently in effect, -the change to the other time occurs. If omitted, the default is -`02:00:00'. - - For example, here is how you would specify the Eastern time zone in -the United States, including the appropriate Daylight Saving Time and -its dates of applicability. The normal offset from UTC is 5 hours; -since this is west of the prime meridian, the sign is positive. Summer -time begins on the first Sunday in April at 2:00am, and ends on the -last Sunday in October at 2:00am. - - EST+5EDT,M4.1.0/2,M10.5.0/2 - - The schedule of Daylight Saving Time in any particular jurisdiction -has changed over the years. To be strictly correct, the conversion of -dates and times in the past should be based on the schedule that was in -effect then. However, this format has no facilities to let you specify -how the schedule has changed from year to year. The most you can do is -specify one particular schedule--usually the present day schedule--and -this is used to convert any date, no matter when. For precise time zone -specifications, it is best to use the time zone information database -(see below). - - The third format looks like this: - - :CHARACTERS - - Each operating system interprets this format differently; in the GNU -C library, CHARACTERS is the name of a file which describes the time -zone. - - If the `TZ' environment variable does not have a value, the -operation chooses a time zone by default. In the GNU C library, the -default time zone is like the specification `TZ=:/etc/localtime' (or -`TZ=:/usr/local/etc/localtime', depending on how GNU C library was -configured; *note Installation::). Other C libraries use their own -rule for choosing the default time zone, so there is little we can say -about them. - - If CHARACTERS begins with a slash, it is an absolute file name; -otherwise the library looks for the file -`/share/lib/zoneinfo/CHARACTERS'. The `zoneinfo' directory contains -data files describing local time zones in many different parts of the -world. The names represent major cities, with subdirectories for -geographical areas; for example, `America/New_York', `Europe/London', -`Asia/Hong_Kong'. These data files are installed by the system -administrator, who also sets `/etc/localtime' to point to the data file -for the local time zone. The GNU C library comes with a large database -of time zone information for most regions of the world, which is -maintained by a community of volunteers and put in the public domain. - - -File: libc.info, Node: Time Zone Functions, Next: Time Functions Example, Prev: TZ Variable, Up: Calendar Time - -Functions and Variables for Time Zones --------------------------------------- - - - Variable: char * tzname [2] - The array `tzname' contains two strings, which are the standard - names of the pair of time zones (standard and Daylight Saving) - that the user has selected. `tzname[0]' is the name of the - standard time zone (for example, `"EST"'), and `tzname[1]' is the - name for the time zone when Daylight Saving Time is in use (for - example, `"EDT"'). These correspond to the STD and DST strings - (respectively) from the `TZ' environment variable. If Daylight - Saving Time is never used, `tzname[1]' is the empty string. - - The `tzname' array is initialized from the `TZ' environment - variable whenever `tzset', `ctime', `strftime', `mktime', or - `localtime' is called. If multiple abbreviations have been used - (e.g. `"EWT"' and `"EDT"' for U.S. Eastern War Time and Eastern - Daylight Time), the array contains the most recent abbreviation. - - The `tzname' array is required for POSIX.1 compatibility, but in - GNU programs it is better to use the `tm_zone' member of the - broken-down time structure, since `tm_zone' reports the correct - abbreviation even when it is not the latest one. - - Though the strings are declared as `char *' the user must refrain - from modifying these strings. Modifying the strings will almost - certainly lead to trouble. - - - - Function: void tzset (void) - The `tzset' function initializes the `tzname' variable from the - value of the `TZ' environment variable. It is not usually - necessary for your program to call this function, because it is - called automatically when you use the other time conversion - functions that depend on the time zone. - - The following variables are defined for compatibility with System V -Unix. Like `tzname', these variables are set by calling `tzset' or the -other time conversion functions. - - - Variable: long int timezone - This contains the difference between UTC and the latest local - standard time, in seconds west of UTC. For example, in the U.S. - Eastern time zone, the value is `5*60*60'. Unlike the `tm_gmtoff' - member of the broken-down time structure, this value is not - adjusted for daylight saving, and its sign is reversed. In GNU - programs it is better to use `tm_gmtoff', since it contains the - correct offset even when it is not the latest one. - - - Variable: int daylight - This variable has a nonzero value if Daylight Saving Time rules - apply. A nonzero value does not necessarily mean that Daylight - Saving Time is now in effect; it means only that Daylight Saving - Time is sometimes in effect. - - -File: libc.info, Node: Time Functions Example, Prev: Time Zone Functions, Up: Calendar Time - -Time Functions Example ----------------------- - - Here is an example program showing the use of some of the calendar -time functions. - - #include - #include - - #define SIZE 256 - - int - main (void) - { - char buffer[SIZE]; - time_t curtime; - struct tm *loctime; - - /* Get the current time. */ - curtime = time (NULL); - - /* Convert it to local time representation. */ - loctime = localtime (&curtime); - - /* Print out the date and time in the standard format. */ - fputs (asctime (loctime), stdout); - - /* Print it out in a nice format. */ - strftime (buffer, SIZE, "Today is %A, %B %d.\n", loctime); - fputs (buffer, stdout); - strftime (buffer, SIZE, "The time is %I:%M %p.\n", loctime); - fputs (buffer, stdout); - - return 0; - } - - It produces output like this: - - Wed Jul 31 13:02:36 1991 - Today is Wednesday, July 31. - The time is 01:02 PM. - diff -u -udbrN glibc-2.3.2/manual/libc.info-37 glibc-2.3.2-200304020432/manual/libc.info-37 --- glibc-2.3.2/manual/libc.info-37 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-37 Thu Jan 1 01:00:00 1970 @@ -1,1233 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

They do this by setting a -timer; when the timer expires, the process receives a signal. - - Each process has three independent interval timers available: - - * A real-time timer that counts elapsed time. This timer sends a - `SIGALRM' signal to the process when it expires. - - * A virtual timer that counts processor time used by the process. - This timer sends a `SIGVTALRM' signal to the process when it - expires. - - * A profiling timer that counts both processor time used by the - process, and processor time spent in system calls on behalf of the - process. This timer sends a `SIGPROF' signal to the process when - it expires. - - This timer is useful for profiling in interpreters. The interval - timer mechanism does not have the fine granularity necessary for - profiling native code. - - You can only have one timer of each kind set at any given time. If -you set a timer that has not yet expired, that timer is simply reset to -the new value. - - You should establish a handler for the appropriate alarm signal using -`signal' or `sigaction' before issuing a call to `setitimer' or -`alarm'. Otherwise, an unusual chain of events could cause the timer -to expire before your program establishes the handler. In this case it -would be terminated, since termination is the default action for the -alarm signals. *Note Signal Handling::. - - To be able to use the alarm function to interrupt a system call which -might block otherwise indefinitely it is important to _not_ set the -`SA_RESTART' flag when registering the signal handler using -`sigaction'. When not using `sigaction' things get even uglier: the -`signal' function has to fixed semantics with respect to restarts. The -BSD semantics for this function is to set the flag. Therefore, if -`sigaction' for whatever reason cannot be used, it is necessary to use -`sysv_signal' and not `signal'. - - The `setitimer' function is the primary means for setting an alarm. -This facility is declared in the header file `sys/time.h'. The `alarm' -function, declared in `unistd.h', provides a somewhat simpler interface -for setting the real-time timer. - - - Data Type: struct itimerval - This structure is used to specify when a timer should expire. It - contains the following members: - `struct timeval it_interval' - This is the period between successive timer interrupts. If - zero, the alarm will only be sent once. - - `struct timeval it_value' - This is the period between now and the first timer interrupt. - If zero, the alarm is disabled. - - The `struct timeval' data type is described in *Note Elapsed - Time::. - - - Function: int setitimer (int WHICH, struct itimerval *NEW, struct - itimerval *OLD) - The `setitimer' function sets the timer specified by WHICH - according to NEW. The WHICH argument can have a value of - `ITIMER_REAL', `ITIMER_VIRTUAL', or `ITIMER_PROF'. - - If OLD is not a null pointer, `setitimer' returns information - about any previous unexpired timer of the same kind in the - structure it points to. - - The return value is `0' on success and `-1' on failure. The - following `errno' error conditions are defined for this function: - - `EINVAL' - The timer period is too large. - - - Function: int getitimer (int WHICH, struct itimerval *OLD) - The `getitimer' function stores information about the timer - specified by WHICH in the structure pointed at by OLD. - - The return value and error conditions are the same as for - `setitimer'. - -`ITIMER_REAL' - This constant can be used as the WHICH argument to the `setitimer' - and `getitimer' functions to specify the real-time timer. - -`ITIMER_VIRTUAL' - This constant can be used as the WHICH argument to the `setitimer' - and `getitimer' functions to specify the virtual timer. - -`ITIMER_PROF' - This constant can be used as the WHICH argument to the `setitimer' - and `getitimer' functions to specify the profiling timer. - - - Function: unsigned int alarm (unsigned int SECONDS) - The `alarm' function sets the real-time timer to expire in SECONDS - seconds. If you want to cancel any existing alarm, you can do - this by calling `alarm' with a SECONDS argument of zero. - - The return value indicates how many seconds remain before the - previous alarm would have been sent. If there is no previous - alarm, `alarm' returns zero. - - The `alarm' function could be defined in terms of `setitimer' like -this: - - unsigned int - alarm (unsigned int seconds) - { - struct itimerval old, new; - new.it_interval.tv_usec = 0; - new.it_interval.tv_sec = 0; - new.it_value.tv_usec = 0; - new.it_value.tv_sec = (long int) seconds; - if (setitimer (ITIMER_REAL, &new, &old) < 0) - return 0; - else - return old.it_value.tv_sec; - } - - There is an example showing the use of the `alarm' function in *Note -Handler Returns::. - - If you simply want your process to wait for a given number of -seconds, you should use the `sleep' function. *Note Sleeping::. - - You shouldn't count on the signal arriving precisely when the timer -expires. In a multiprocessing environment there is typically some -amount of delay involved. - - *Portability Note:* The `setitimer' and `getitimer' functions are -derived from BSD Unix, while the `alarm' function is specified by the -POSIX.1 standard. `setitimer' is more powerful than `alarm', but -`alarm' is more widely used. - - -File: libc.info, Node: Sleeping, Prev: Setting an Alarm, Up: Date and Time - -Sleeping -======== - - The function `sleep' gives a simple way to make the program wait for -a short interval. If your program doesn't use signals (except to -terminate), then you can expect `sleep' to wait reliably throughout the -specified interval. Otherwise, `sleep' can return sooner if a signal -arrives; if you want to wait for a given interval regardless of -signals, use `select' (*note Waiting for I/O::) and don't specify any -descriptors to wait for. - - - Function: unsigned int sleep (unsigned int SECONDS) - The `sleep' function waits for SECONDS or until a signal is - delivered, whichever happens first. - - If `sleep' function returns because the requested interval is over, - it returns a value of zero. If it returns because of delivery of a - signal, its return value is the remaining time in the sleep - interval. - - The `sleep' function is declared in `unistd.h'. - - Resist the temptation to implement a sleep for a fixed amount of -time by using the return value of `sleep', when nonzero, to call -`sleep' again. This will work with a certain amount of accuracy as -long as signals arrive infrequently. But each signal can cause the -eventual wakeup time to be off by an additional second or so. Suppose a -few signals happen to arrive in rapid succession by bad luck--there is -no limit on how much this could shorten or lengthen the wait. - - Instead, compute the calendar time at which the program should stop -waiting, and keep trying to wait until that calendar time. This won't -be off by more than a second. With just a little more work, you can use -`select' and make the waiting period quite accurate. (Of course, heavy -system load can cause additional unavoidable delays--unless the machine -is dedicated to one application, there is no way you can avoid this.) - - On some systems, `sleep' can do strange things if your program uses -`SIGALRM' explicitly. Even if `SIGALRM' signals are being ignored or -blocked when `sleep' is called, `sleep' might return prematurely on -delivery of a `SIGALRM' signal. If you have established a handler for -`SIGALRM' signals and a `SIGALRM' signal is delivered while the process -is sleeping, the action taken might be just to cause `sleep' to return -instead of invoking your handler. And, if `sleep' is interrupted by -delivery of a signal whose handler requests an alarm or alters the -handling of `SIGALRM', this handler and `sleep' will interfere. - - On the GNU system, it is safe to use `sleep' and `SIGALRM' in the -same program, because `sleep' does not work by means of `SIGALRM'. - - - Function: int nanosleep (const struct timespec *REQUESTED_TIME, - struct timespec *REMAINING) - If resolution to seconds is not enough the `nanosleep' function can - be used. As the name suggests the sleep interval can be specified - in nanoseconds. The actual elapsed time of the sleep interval - might be longer since the system rounds the elapsed time you - request up to the next integer multiple of the actual resolution - the system can deliver. - - *`requested_time' is the elapsed time of the interval you want to - sleep. - - The function returns as *`remaining' the elapsed time left in the - interval for which you requested to sleep. If the interval - completed without getting interrupted by a signal, this is zero. - - `struct timespec' is described in *Note Elapsed Time::. - - If the function returns because the interval is over the return - value is zero. If the function returns -1 the global variable - ERRNO is set to the following values: - - `EINTR' - The call was interrupted because a signal was delivered to - the thread. If the REMAINING parameter is not the null - pointer the structure pointed to by REMAINING is updated to - contain the remaining elapsed time. - - `EINVAL' - The nanosecond value in the REQUESTED_TIME parameter contains - an illegal value. Either the value is negative or greater - than or equal to 1000 million. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `nanosleep' is called. If the thread gets canceled these - resources stay allocated until the program ends. To avoid this - calls to `nanosleep' should be protected using cancellation - handlers. - - The `nanosleep' function is declared in `time.h'. - - -File: libc.info, Node: Resource Usage And Limitation, Next: Non-Local Exits, Prev: Date and Time, Up: Top - -Resource Usage And Limitation -***************************** - - This chapter describes functions for examining how much of various -kinds of resources (CPU time, memory, etc.) a process has used and -getting and setting limits on future usage. - -* Menu: - -* Resource Usage:: Measuring various resources used. -* Limits on Resources:: Specifying limits on resource usage. -* Priority:: Reading or setting process run priority. -* Memory Resources:: Querying memory available resources. -* Processor Resources:: Learn about the processors available. - - -File: libc.info, Node: Resource Usage, Next: Limits on Resources, Up: Resource Usage And Limitation - -Resource Usage -============== - - The function `getrusage' and the data type `struct rusage' are used -to examine the resource usage of a process.

When the -process tries to exceed a limit, it may get a signal, or the system call -by which it tried to do so may fail, depending on the resource. Each -process initially inherits its limit values from its parent, but it can -subsequently change them. - - There are two per-process limits associated with a resource: - -"current limit" - The current limit is the value the system will not allow usage to - exceed. It is also called the "soft limit" because the process - being limited can generally raise the current limit at will. - -"maximum limit" - The maximum limit is the maximum value to which a process is - allowed to set its current limit. It is also called the "hard - limit" because there is no way for a process to get around it. A - process may lower its own maximum limit, but only the superuser - may increase a maximum limit. - - The symbols for use with `getrlimit', `setrlimit', `getrlimit64', -and `setrlimit64' are defined in `sys/resource.h'. - - - Function: int getrlimit (int RESOURCE, struct rlimit *RLP) - Read the current and maximum limits for the resource RESOURCE and - store them in `*RLP'. - - The return value is `0' on success and `-1' on failure.

Thus, the - LFS interface transparently replaces the old interface. - - - Function: int getrlimit64 (int RESOURCE, struct rlimit64 *RLP) - This function is similar to `getrlimit' but its second parameter is - a pointer to a variable of type `struct rlimit64', which allows it - to read values which wouldn't fit in the member of a `struct - rlimit'. - - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit machine, this function is available under the name - `getrlimit' and so transparently replaces the old interface. - - - Function: int setrlimit (int RESOURCE, const struct rlimit *RLP) - Store the current and maximum limits for the resource RESOURCE in - `*RLP'. - - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is possible: - - `EPERM' - * The process tried to raise a current limit beyond the - maximum limit. - - * The process tried to raise a maximum limit, but is not - superuser. - - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `setrlimit64'.

It has two fields: - - `rlim_t rlim_cur' - The current limit - - `rlim_t rlim_max' - The maximum limit. - - For `getrlimit', the structure is an output; it receives the - current values. For `setrlimit', it specifies the new values. - - For the LFS functions a similar type is defined in `sys/resource.h'. - - - Data Type: struct rlimit64 - This structure is analogous to the `rlimit' structure above, but - its components have wider ranges. It has two fields: - - `rlim64_t rlim_cur' - This is analogous to `rlimit.rlim_cur', but with a different - type. - - `rlim64_t rlim_max' - This is analogous to `rlimit.rlim_max', but with a different - type. - - - Here is a list of resources for which you can specify a limit. -Memory and file sizes are measured in bytes. - -`RLIMIT_CPU' - The maximum amount of CPU time the process can use. If it runs for - longer than this, it gets a signal: `SIGXCPU'. The value is - measured in seconds. *Note Operation Error Signals::. - -`RLIMIT_FSIZE' - The maximum size of file the process can create. Trying to write a - larger file causes a signal: `SIGXFSZ'. *Note Operation Error - Signals::. - -`RLIMIT_DATA' - The maximum size of data memory for the process.

If the process tries to - extend its stack past this size, it gets a `SIGSEGV' signal. - *Note Program Error Signals::. - -`RLIMIT_CORE' - The maximum size core file that this process can create. If the - process terminates and would dump a core file larger than this, - then no core file is created. So setting this limit to zero - prevents core files from ever being created. - -`RLIMIT_RSS' - The maximum amount of physical memory that this process should get. - This parameter is a guide for the system's scheduler and memory - allocator; the system may give the process more memory when there - is a surplus. - -`RLIMIT_MEMLOCK' - The maximum amount of memory that can be locked into physical - memory (so it will never be paged out). - -`RLIMIT_NPROC' - The maximum number of processes that can be created with the same - user ID. If you have reached the limit for your user ID, `fork' - will fail with `EAGAIN'. *Note Creating a Process::. - -`RLIMIT_NOFILE' -`RLIMIT_OFILE' - The maximum number of files that the process can open. If it - tries to open more files than this, its open attempt fails with - `errno' `EMFILE'. *Note Error Codes::.

The functions above are better choices. - - `ulimit' and the command symbols are declared in `ulimit.h'. - - - Function: int ulimit (int CMD, ...) - `ulimit' gets the current limit or sets the current and maximum - limit for a particular resource for the calling process according - to the command CMD.a - - If you are getting a limit, the command argument is the only - argument. If you are setting a limit, there is a second argument: - `long int' LIMIT which is the value to which you are setting the - limit. - - The CMD values and the operations they specify are: - `GETFSIZE' - Get the current limit on the size of a file, in units of 512 - bytes. - - `SETFSIZE' - Set the current and maximum limit on the size of a file to - LIMIT * 512 bytes. - - There are also some other CMD values that may do things on some - systems, but they are not supported. - - Only the superuser may increase a maximum limit. - - When you successfully get a limit, the return value of `ulimit' is - that limit, which is never negative. When you successfully set a - limit, the return value is zero. When the function fails, the - return value is `-1' and `errno' is set according to the reason: - - `EPERM' - A process tried to increase a maximum limit, but is not - superuser. - - - `vlimit' and its resource symbols are declared in `sys/vlimit.h'. - - - Function: int vlimit (int RESOURCE, int LIMIT) - `vlimit' sets the current limit for a resource for a process. - - RESOURCE identifies the resource: - - `LIM_CPU' - Maximum CPU time. Same as `RLIMIT_CPU' for `setrlimit'. - - `LIM_FSIZE' - Maximum file size. Same as `RLIMIT_FSIZE' for `setrlimit'. - - `LIM_DATA' - Maximum data memory. Same as `RLIMIT_DATA' for `setrlimit'. - - `LIM_STACK' - Maximum stack size. Same as `RLIMIT_STACK' for `setrlimit'. - - `LIM_CORE' - Maximum core file size. Same as `RLIMIT_COR' for `setrlimit'. - - `LIM_MAXRSS' - Maximum physical memory. Same as `RLIMIT_RSS' for - `setrlimit'. - - The return value is zero for success, and `-1' with `errno' set - accordingly for failure: - - `EPERM' - The process tried to set its current limit beyond its maximum - limit. - - - -File: libc.info, Node: Priority, Next: Memory Resources, Prev: Limits on Resources, Up: Resource Usage And Limitation - -Process CPU Priority And Scheduling -=================================== - - When multiple processes simultaneously require CPU time, the system's -scheduling policy and process CPU priorities determine which processes -get it. This section describes how that determination is made and GNU -C library functions to control it. - - It is common to refer to CPU scheduling simply as scheduling and a -process' CPU priority simply as the process' priority, with the CPU -resource being implied. Bear in mind, though, that CPU time is not the -only resource a process uses or that processes contend for. In some -cases, it is not even particularly important. Giving a process a high -"priority" may have very little effect on how fast a process runs with -respect to other processes. The priorities discussed in this section -apply only to CPU time. - - CPU scheduling is a complex issue and different systems do it in -wildly different ways. New ideas continually develop and find their -way into the intricacies of the various systems' scheduling algorithms. -This section discusses the general concepts, some specifics of systems -that commonly use the GNU C library, and some standards. - - For simplicity, we talk about CPU contention as if there is only one -CPU in the system. But all the same principles apply when a processor -has multiple CPUs, and knowing that the number of processes that can -run at any one time is equal to the number of CPUs, you can easily -extrapolate the information. - - The functions described in this section are all defined by the -POSIX.1 and POSIX.1b standards (the `sched...' functions are POSIX.1b). -However, POSIX does not define any semantics for the values that these -functions get and set. In this chapter, the semantics are based on the -Linux kernel's implementation of the POSIX standard. As you will see, -the Linux implementation is quite the inverse of what the authors of the -POSIX syntax had in mind. - -* Menu: - -* Absolute Priority:: The first tier of priority. Posix -* Realtime Scheduling:: Scheduling among the process nobility -* Basic Scheduling Functions:: Get/set scheduling policy, priority -* Traditional Scheduling:: Scheduling among the vulgar masses - - -File: libc.info, Node: Absolute Priority, Next: Realtime Scheduling, Up: Priority - -Absolute Priority ------------------ - - Every process has an absolute priority, and it is represented by a -number. The higher the number, the higher the absolute priority. - - On systems of the past, and most systems today, all processes have -absolute priority 0 and this section is irrelevant. In that case, -*Note Traditional Scheduling::. Absolute priorities were invented to -accommodate realtime systems, in which it is vital that certain -processes be able to respond to external events happening in real time, -which means they cannot wait around while some other process that _wants -to_, but doesn't _need to_ run occupies the CPU. - - When two processes are in contention to use the CPU at any instant, -the one with the higher absolute priority always gets it. This is true -even if the process with the lower priority is already using the CPU -(i.e. the scheduling is preemptive). Of course, we're only talking -about processes that are running or "ready to run," which means they are -ready to execute instructions right now. When a process blocks to wait -for something like I/O, its absolute priority is irrelevant. - - *Note:* The term "runnable" is a synonym for "ready to run." - - When two processes are running or ready to run and both have the same -absolute priority, it's more interesting. In that case, who gets the -CPU is determined by the scheduling policy. If the processes have -absolute priority 0, the traditional scheduling policy described in -*Note Traditional Scheduling:: applies. Otherwise, the policies -described in *Note Realtime Scheduling:: apply. - - You normally give an absolute priority above 0 only to a process that -can be trusted not to hog the CPU. Such processes are designed to block -(or terminate) after relatively short CPU runs. - - A process begins life with the same absolute priority as its parent -process. Functions described in *Note Basic Scheduling Functions:: can -change it. - - Only a privileged process can change a process' absolute priority to -something other than `0'. Only a privileged process or the target -process' owner can change its absolute priority at all. - - POSIX requires absolute priority values used with the realtime -scheduling policies to be consecutive with a range of at least 32. On -Linux, they are 1 through 99. The functions `sched_get_priority_max' -and `sched_set_priority_min' portably tell you what the range is on a -particular system. - -Using Absolute Priority -....................... - - One thing you must keep in mind when designing real time -applications is that having higher absolute priority than any other -process doesn't guarantee the process can run continuously. Two things -that can wreck a good CPU run are interrupts and page faults. - - Interrupt handlers live in that limbo between processes. The CPU is -executing instructions, but they aren't part of any process. An -interrupt will stop even the highest priority process. So you must -allow for slight delays and make sure that no device in the system has -an interrupt handler that could cause too long a delay between -instructions for your process. - - Similarly, a page fault causes what looks like a straightforward -sequence of instructions to take a long time. The fact that other -processes get to run while the page faults in is of no consequence, -because as soon as the I/O is complete, the high priority process will -kick them out and run again, but the wait for the I/O itself could be a -problem. To neutralize this threat, use `mlock' or `mlockall'. - - There are a few ramifications of the absoluteness of this priority -on a single-CPU system that you need to keep in mind when you choose to -set a priority and also when you're working on a program that runs with -high absolute priority. Consider a process that has higher absolute -priority than any other process in the system and due to a bug in its -program, it gets into an infinite loop. It will never cede the CPU. -You can't run a command to kill it because your command would need to -get the CPU in order to run. The errant program is in complete -control. It controls the vertical, it controls the horizontal. - - There are two ways to avoid this: 1) keep a shell running somewhere -with a higher absolute priority. 2) keep a controlling terminal -attached to the high priority process group. All the priority in the -world won't stop an interrupt handler from running and delivering a -signal to the process if you hit Control-C. - - Some systems use absolute priority as a means of allocating a fixed -percentage of CPU time to a process. To do this, a super high priority -privileged process constantly monitors the process' CPU usage and raises -its absolute priority when the process isn't getting its entitled share -and lowers it when the process is exceeding it. - - *Note:* The absolute priority is sometimes called the "static -priority." We don't use that term in this manual because it misses the -most important feature of the absolute priority: its absoluteness. - - -File: libc.info, Node: Realtime Scheduling, Next: Basic Scheduling Functions, Prev: Absolute Priority, Up: Priority - -Realtime Scheduling -------------------- - - Whenever two processes with the same absolute priority are ready to -run, the kernel has a decision to make, because only one can run at a -time. If the processes have absolute priority 0, the kernel makes this -decision as described in *Note Traditional Scheduling::. Otherwise, -the decision is as described in this section. - - If two processes are ready to run but have different absolute -priorities, the decision is much simpler, and is described in *Note -Absolute Priority::. - - Each process has a scheduling policy. For processes with absolute -priority other than zero, there are two available: - - 1. First Come First Served - - 2. Round Robin - - The most sensible case is where all the processes with a certain -absolute priority have the same scheduling policy. We'll discuss that -first. - - In Round Robin, processes share the CPU, each one running for a small -quantum of time ("time slice") and then yielding to another in a -circular fashion. Of course, only processes that are ready to run and -have the same absolute priority are in this circle. - - In First Come First Served, the process that has been waiting the -longest to run gets the CPU, and it keeps it until it voluntarily -relinquishes the CPU, runs out of things to do (blocks), or gets -preempted by a higher priority process. - - First Come First Served, along with maximal absolute priority and -careful control of interrupts and page faults, is the one to use when a -process absolutely, positively has to run at full CPU speed or not at -all. - - Judicious use of `sched_yield' function invocations by processes -with First Come First Served scheduling policy forms a good compromise -between Round Robin and First Come First Served. - - To understand how scheduling works when processes of different -scheduling policies occupy the same absolute priority, you have to know -the nitty gritty details of how processes enter and exit the ready to -run list: - - In both cases, the ready to run list is organized as a true queue, -where a process gets pushed onto the tail when it becomes ready to run -and is popped off the head when the scheduler decides to run it. Note -that ready to run and running are two mutually exclusive states. When -the scheduler runs a process, that process is no longer ready to run -and no longer in the ready to run list. When the process stops -running, it may go back to being ready to run again. - - The only difference between a process that is assigned the Round -Robin scheduling policy and a process that is assigned First Come First -Serve is that in the former case, the process is automatically booted -off the CPU after a certain amount of time. When that happens, the -process goes back to being ready to run, which means it enters the -queue at the tail. The time quantum we're talking about is small. -Really small. This is not your father's timesharing. For example, -with the Linux kernel, the round robin time slice is a thousand times -shorter than its typical time slice for traditional scheduling. - - A process begins life with the same scheduling policy as its parent -process. Functions described in *Note Basic Scheduling Functions:: can -change it. - - Only a privileged process can set the scheduling policy of a process -that has absolute priority higher than 0. - - -File: libc.info, Node: Basic Scheduling Functions, Next: Traditional Scheduling, Prev: Realtime Scheduling, Up: Priority - -Basic Scheduling Functions --------------------------- - - This section describes functions in the GNU C library for setting the -absolute priority and scheduling policy of a process. - - *Portability Note:* On systems that have the functions in this -section, the macro _POSIX_PRIORITY_SCHEDULING is defined in -`'. - - For the case that the scheduling policy is traditional scheduling, -more functions to fine tune the scheduling are in *Note Traditional -Scheduling::. - - Don't try to make too much out of the naming and structure of these -functions. They don't match the concepts described in this manual -because the functions are as defined by POSIX.1b, but the implementation -on systems that use the GNU C library is the inverse of what the POSIX -structure contemplates. The POSIX scheme assumes that the primary -scheduling parameter is the scheduling policy and that the priority -value, if any, is a parameter of the scheduling policy.

So this -section describes the only scheduling many programmers need to be -concerned about. - - But just to be clear about the scope of this scheduling: Any time a -process with a absolute priority of 0 and a process with an absolute -priority higher than 0 are ready to run at the same time, the one with -absolute priority 0 does not run. If it's already running when the -higher priority ready-to-run process comes into existence, it stops -immediately. - - In addition to its absolute priority of zero, every process has -another priority, which we will refer to as "dynamic priority" because -it changes over time. The dynamic priority is meaningless for -processes with an absolute priority higher than zero. - - The dynamic priority sometimes determines who gets the next turn on -the CPU. Sometimes it determines how long turns last. Sometimes it -determines whether a process can kick another off the CPU. - - In Linux, the value is a combination of these things, but mostly it -is just determines the length of the time slice. The higher a process' -dynamic priority, the longer a shot it gets on the CPU when it gets one. -If it doesn't use up its time slice before giving up the CPU to do -something like wait for I/O, it is favored for getting the CPU back when -it's ready for it, to finish out its time slice. Other than that, -selection of processes for new time slices is basically round robin. -But the scheduler does throw a bone to the low priority processes: A -process' dynamic priority rises every time it is snubbed in the -scheduling process. In Linux, even the fat kid gets to play. - - The fluctuation of a process' dynamic priority is regulated by -another value: The "nice" value. The nice value is an integer, usually -in the range -20 to 20, and represents an upper limit on a process' -dynamic priority. The higher the nice number, the lower that limit. - - On a typical Linux system, for example, a process with a nice value -of 20 can get only 10 milliseconds on the CPU at a time, whereas a -process with a nice value of -20 can achieve a high enough priority to -get 400 milliseconds. - - The idea of the nice value is deferential courtesy. In the -beginning, in the Unix garden of Eden, all processes shared equally in -the bounty of the computer system. But not all processes really need -the same share of CPU time, so the nice value gave a courteous process -the ability to refuse its equal share of CPU time that others might -prosper. Hence, the higher a process' nice value, the nicer the -process is. (Then a snake came along and offered some process a -negative nice value and the system became the crass resource allocation -system we know today). - - Dynamic priorities tend upward and downward with an objective of -smoothing out allocation of CPU time and giving quick response time to -infrequent requests. But they never exceed their nice limits, so on a -heavily loaded CPU, the nice value effectively determines how fast a -process runs. - - In keeping with the socialistic heritage of Unix process priority, a -process begins life with the same nice value as its parent process and -can raise it at will. A process can also raise the nice value of any -other process owned by the same user (or effective user). But only a -privileged process can lower its nice value. A privileged process can -also raise or lower another process' nice value. - - GNU C Library functions for getting and setting nice values are -described in *Note Traditional Scheduling Functions::. - diff -u -udbrN glibc-2.3.2/manual/libc.info-38 glibc-2.3.2-200304020432/manual/libc.info-38 --- glibc-2.3.2/manual/libc.info-38 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-38 Thu Jan 1 01:00:00 1970 @@ -1,1105 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

This -means that the addresses of the memory regions do not have to correspond -directly to the addresses of the actual physical memory which stores the -data. An extra level of indirection is introduced which translates -virtual addresses into physical addresses. This is normally done by the -hardware of the processor. - - Using a virtual address space has several advantage. The most -important is process isolation. The different processes running on the -system cannot interfere directly with each other. No process can write -into the address space of another process (except when shared memory is -used but then it is wanted and controlled). - - Another advantage of virtual memory is that the address space the -processes see can actually be larger than the physical memory available. -The physical memory can be extended by storage on an external media -where the content of currently unused memory regions is stored. The -address translation can then intercept accesses to these memory regions -and make memory content available again by loading the data back into -memory. This concept makes it necessary that programs which have to use -lots of memory know the difference between available virtual address -space and available physical memory. If the working set of virtual -memory of all the processes is larger than the available physical memory -the system will slow down dramatically due to constant swapping of -memory content from the memory to the storage media and back. This is -called "thrashing". - - A final aspect of virtual memory which is important and follows from -what is said in the last paragraph is the granularity of the virtual -address space handling. When we said that the virtual address handling -stores memory content externally it cannot do this on a byte-by-byte -basis. The administrative overhead does not allow this (leaving alone -the processor hardware). Instead several thousand bytes are handled -together and form a "page". The size of each page is always a power of -two byte. The smallest page size in use today is 4096, with 8192, -16384, and 65536 being other popular sizes. - - -File: libc.info, Node: Query Memory Parameters, Prev: Memory Subsystem, Up: Memory Resources - -How to get information about the memory subsystem? --------------------------------------------------- - - The page size of the virtual memory the process sees is essential to -know in several situations. Some programming interface (e.g., `mmap', -*note Memory-mapped I/O::) require the user to provide information -adjusted to the page size. In the case of `mmap' is it necessary to -provide a length argument which is a multiple of the page size. -Another place where the knowledge about the page size is useful is in -memory allocation. If one allocates pieces of memory in larger chunks -which are then subdivided by the application code it is useful to -adjust the size of the larger blocks to the page size. If the total -memory requirement for the block is close (but not larger) to a multiple -of the page size the kernel's memory handling can work more effectively -since it only has to allocate memory pages which are fully used. (To do -this optimization it is necessary to know a bit about the memory -allocator which will require a bit of memory itself for each block and -this overhead must not push the total size over the page size multiple. - - The page size traditionally was a compile time constant. But recent -development of processors changed this. Processors now support -different page sizes and they can possibly even vary among different -processes on the same system. Therefore the system should be queried at -runtime about the current page size and no assumptions (except about it -being a power of two) should be made. - - The correct interface to query about the page size is `sysconf' -(*note Sysconf Definition::) with the parameter `_SC_PAGESIZE'.

The value returned -for `_SC_AVPHYS_PAGES' is the amount of memory the application can use -without hindering any other process (given that no other process -increases its memory usage). The value returned for `_SC_PHYS_PAGES' -is more or less a hard limit for the working set.

Suppose the "read" command reads -input from a file, doing some lexical analysis and parsing of the input -while processing it. If a low-level input error is detected, it would -be useful to be able to return immediately to the "main loop" instead -of having to make each of the lexical analysis, parsing, and processing -phases all have to explicitly deal with error situations initially -detected by nested calls. - - (On the other hand, if each of these phases has to do a substantial -amount of cleanup when it exits--such as closing files, deallocating -buffers or other data structures, and the like--then it can be more -appropriate to do a normal return and have each phase do its own -cleanup, because a non-local exit would bypass the intervening phases -and their associated cleanup code entirely. Alternatively, you could -use a non-local exit but do the cleanup explicitly either before or -after returning to the "main loop".) - - In some ways, a non-local exit is similar to using the `return' -statement to return from a function. But while `return' abandons only -a single function call, transferring control back to the point at which -it was called, a non-local exit can potentially abandon many levels of -nested function calls. - - You identify return points for non-local exits by calling the -function `setjmp'. This function saves information about the execution -environment in which the call to `setjmp' appears in an object of type -`jmp_buf'. Execution of the program continues normally after the call -to `setjmp', but if an exit is later made to this return point by -calling `longjmp' with the corresponding `jmp_buf' object, control is -transferred back to the point where `setjmp' was called. The return -value from `setjmp' is used to distinguish between an ordinary return -and a return made by a call to `longjmp', so calls to `setjmp' usually -appear in an `if' statement. - - Here is how the example program described above might be set up: - - #include - #include - #include - - jmp_buf main_loop; - - void - abort_to_main_loop (int status) - { - longjmp (main_loop, status); - } - - int - main (void) - { - while (1) - if (setjmp (main_loop)) - puts ("Back at main loop...."); - else - do_command (); - } - - - void - do_command (void) - { - char buffer[128]; - if (fgets (buffer, 128, stdin) == NULL) - abort_to_main_loop (-1); - else - exit (EXIT_SUCCESS); - } - - The function `abort_to_main_loop' causes an immediate transfer of -control back to the main loop of the program, no matter where it is -called from. - - The flow of control inside the `main' function may appear a little -mysterious at first, but it is actually a common idiom with `setjmp'. -A normal call to `setjmp' returns zero, so the "else" clause of the -conditional is executed. If `abort_to_main_loop' is called somewhere -within the execution of `do_command', then it actually appears as if -the _same_ call to `setjmp' in `main' were returning a second time with -a value of `-1'. - - So, the general pattern for using `setjmp' looks something like: - - if (setjmp (BUFFER)) - /* Code to clean up after premature return. */ - ... - else - /* Code to be executed normally after setting up the return point. */ - ... - - -File: libc.info, Node: Non-Local Details, Next: Non-Local Exits and Signals, Prev: Non-Local Intro, Up: Non-Local Exits - -Details of Non-Local Exits -========================== - - Here are the details on the functions and data structures used for -performing non-local exits. These facilities are declared in -`setjmp.h'. - - - Data Type: jmp_buf - Objects of type `jmp_buf' hold the state information to be - restored by a non-local exit. The contents of a `jmp_buf' - identify a specific place to return to. - - - Macro: int setjmp (jmp_buf STATE) - When called normally, `setjmp' stores information about the - execution state of the program in STATE and returns zero. If - `longjmp' is later used to perform a non-local exit to this STATE, - `setjmp' returns a nonzero value. - - - Function: void longjmp (jmp_buf STATE, int VALUE) - This function restores current execution to the state saved in - STATE, and continues execution from the call to `setjmp' that - established that return point. Returning from `setjmp' by means of - `longjmp' returns the VALUE argument that was passed to `longjmp', - rather than `0'. (But if VALUE is given as `0', `setjmp' returns - `1'). - - There are a lot of obscure but important restrictions on the use of -`setjmp' and `longjmp'. Most of these restrictions are present because -non-local exits require a fair amount of magic on the part of the C -compiler and can interact with other parts of the language in strange -ways. - - The `setjmp' function is actually a macro without an actual function -definition, so you shouldn't try to `#undef' it or take its address. -In addition, calls to `setjmp' are safe in only the following contexts: - - * As the test expression of a selection or iteration statement (such - as `if', `switch', or `while'). - - * As one operand of a equality or comparison operator that appears - as the test expression of a selection or iteration statement. The - other operand must be an integer constant expression. - - * As the operand of a unary `!' operator, that appears as the test - expression of a selection or iteration statement. - - * By itself as an expression statement. - - Return points are valid only during the dynamic extent of the -function that called `setjmp' to establish them. If you `longjmp' to a -return point that was established in a function that has already -returned, unpredictable and disastrous things are likely to happen. - - You should use a nonzero VALUE argument to `longjmp'. While -`longjmp' refuses to pass back a zero argument as the return value from -`setjmp', this is intended as a safety net against accidental misuse -and is not really good programming style. - - When you perform a non-local exit, accessible objects generally -retain whatever values they had at the time `longjmp' was called. The -exception is that the values of automatic variables local to the -function containing the `setjmp' call that have been changed since the -call to `setjmp' are indeterminate, unless you have declared them -`volatile'. - - -File: libc.info, Node: Non-Local Exits and Signals, Next: System V contexts, Prev: Non-Local Details, Up: Non-Local Exits - -Non-Local Exits and Signals -=========================== - - In BSD Unix systems, `setjmp' and `longjmp' also save and restore -the set of blocked signals; see *Note Blocking Signals::. However, the -POSIX.1 standard requires `setjmp' and `longjmp' not to change the set -of blocked signals, and provides an additional pair of functions -(`sigsetjmp' and `siglongjmp') to get the BSD behavior. - - The behavior of `setjmp' and `longjmp' in the GNU library is -controlled by feature test macros; see *Note Feature Test Macros::.

If SAVESIGS is nonzero, the set of - blocked signals is saved in STATE and will be restored if a - `siglongjmp' is later performed with this STATE. - - - Function: void siglongjmp (sigjmp_buf STATE, int VALUE) - This is similar to `longjmp' except for the type of its STATE - argument. If the `sigsetjmp' call that set this STATE used a - nonzero SAVESIGS flag, `siglongjmp' also restores the set of - blocked signals. - - -File: libc.info, Node: System V contexts, Prev: Non-Local Exits and Signals, Up: Non-Local Exits - -Complete Context Control -======================== - - The Unix standard one more set of function to control the execution -path and these functions are more powerful than those discussed in this -chapter so far.

Not all -platforms and/or architectures the GNU C Library is available on provide -this interface. Use `configure' to detect the availability. - - Similar to the `jmp_buf' and `sigjmp_buf' types used for the -variables to contain the state of the `longjmp' functions the -interfaces of interest here have an appropriate type as well. Objects -of this type are normally much larger since more information is -contained. The type is also used in a few more places as we will see. -The types and functions described in this section are all defined and -declared respectively in the `ucontext.h' header file. - - - Data Type: ucontext_t - The `ucontext_t' type is defined as a structure with as least the - following elements: - - `ucontext_t *uc_link' - This is a pointer to the next context structure which is used - if the context described in the current structure returns. - - `sigset_t uc_sigmask' - Set of signals which are blocked when this context is used. - - `stack_t uc_stack' - Stack used for this context. The value need not be (and - normally is not) the stack pointer. *Note Signal Stack::. - - `mcontext_t uc_mcontext' - This element contains the actual state of the process. The - `mcontext_t' type is also defined in this header but the - definition should be treated as opaque. Any use of knowledge - of the type makes applications less portable. - - - Objects of this type have to be created by the user. The -initialization and modification happens through one of the following -functions: - - - Function: int getcontext (ucontext_t *UCP) - The `getcontext' function initializes the variable pointed to by - UCP with the context of the calling thread. The context contains - the content of the registers, the signal mask, and the current - stack. Executing the contents would start at the point where the - `getcontext' call just returned. - - The function returns `0' if successful. Otherwise it returns `-1' - and sets ERRNO accordingly. - - The `getcontext' function is similar to `setjmp' but it does not -provide an indication of whether the function returns for the first -time or whether the initialized context was used and the execution is -resumed at just that point. If this is necessary the user has to take -determine this herself. This must be done carefully since the context -contains registers which might contain register variables. This is a -good situation to define variables with `volatile'. - - Once the context variable is initialized it can be used as is or it -can be modified. The latter is normally done to implement co-routines -or similar constructs. The `makecontext' function is what has to be -used to do that. - - - Function: void makecontext (ucontext_t *UCP, void (*FUNC) (void), - int ARGC, ...) - The UCP parameter passed to the `makecontext' shall be initialized - by a call to `getcontext'. The context will be modified to in a - way so that if the context is resumed it will start by calling the - function `func' which gets ARGC integer arguments passed. The - integer arguments which are to be passed should follow the ARGC - parameter in the call to `makecontext'. - - Before the call to this function the `uc_stack' and `uc_link' - element of the UCP structure should be initialized. The - `uc_stack' element describes the stack which is used for this - context. No two contexts which are used at the same time should - use the same memory region for a stack. - - The `uc_link' element of the object pointed to by UCP should be a - pointer to the context to be executed when the function FUNC - returns or it should be a null pointer. See `setcontext' for more - information about the exact use. - - While allocating the memory for the stack one has to be careful. -Most modern processors keep track of whether a certain memory region is -allowed to contain code which is executed or not. Data segments and -heap memory is normally not tagged to allow this. The result is that -programs would fail. Examples for such code include the calling -sequences the GNU C compiler generates for calls to nested functions. -Safe ways to allocate stacks correctly include using memory on the -original threads stack or explicitly allocate memory tagged for -execution using (*note Memory-mapped I/O::). - - *Compatibility note*: The current Unix standard is very imprecise -about the way the stack is allocated. All implementations seem to agree -that the `uc_stack' element must be used but the values stored in the -elements of the `stack_t' value are unclear. The GNU C library and -most other Unix implementations require the `ss_sp' value of the -`uc_stack' element to point to the base of the memory region allocated -for the stack and the size of the memory region is stored in `ss_size'. -There are implements out there which require `ss_sp' to be set to the -value the stack pointer will have (which can depending on the direction -the stack grows be different). This difference makes the `makecontext' -function hard to use and it requires detection of the platform at -compile time. - - - Function: int setcontext (const ucontext_t *UCP) - The `setcontext' function restores the context described by UCP. - The context is not modified and can be reused as often as wanted. - - If the context was created by `getcontext' execution resumes with - the registers filled with the same values and the same stack as if - the `getcontext' call just returned. - - If the context was modified with a call to `makecontext' execution - continues with the function passed to `makecontext' which gets the - specified parameters passed. If this function returns execution is - resumed in the context which was referenced by the `uc_link' - element of the context structure passed to `makecontext' at the - time of the call. If `uc_link' was a null pointer the application - terminates in this case. - - Since the context contains information about the stack no two - threads should use the same context at the same time. The result - in most cases would be disastrous. - - The `setcontext' function does not return unless an error occurred - in which case it returns `-1'. - - The `setcontext' function simply replaces the current context with -the one described by the UCP parameter. This is often useful but there -are situations where the current context has to be preserved. - - - Function: int swapcontext (ucontext_t *restrict OUCP, const - ucontext_t *restrict UCP) - The `swapcontext' function is similar to `setcontext' but instead - of just replacing the current context the latter is first saved in - the object pointed to by OUCP as if this was a call to - `getcontext'. The saved context would resume after the call to - `swapcontext'. - - Once the current context is saved the context described in UCP is - installed and execution continues as described in this context. - - If `swapcontext' succeeds the function does not return unless the - context OUCP is used without prior modification by `makecontext'. - The return value in this case is `0'. If the function fails it - returns `-1' and set ERRNO accordingly. - -Example for SVID Context Handling -================================= - - The easiest way to use the context handling functions is as a -replacement for `setjmp' and `longjmp'.

Other kinds of signals that report -harmless events are ignored by default. - - If you anticipate an event that causes signals, you can define a -handler function and tell the operating system to run it when that -particular type of signal arrives. - - Finally, one process can send a signal to another process; this -allows a parent process to abort a child, or two related processes to -communicate and synchronize. - -* Menu: - -* Concepts of Signals:: Introduction to the signal facilities. -* Standard Signals:: Particular kinds of signals with - standard names and meanings. -* Signal Actions:: Specifying what happens when a - particular signal is delivered. -* Defining Handlers:: How to write a signal handler function. -* Interrupted Primitives:: Signal handlers affect use of `open', - `read', `write' and other functions. -* Generating Signals:: How to send a signal to a process. -* Blocking Signals:: Making the system hold signals temporarily. -* Waiting for a Signal:: Suspending your program until a signal - arrives. -* Signal Stack:: Using a Separate Signal Stack. -* BSD Signal Handling:: Additional functions for backward - compatibility with BSD. - - -File: libc.info, Node: Concepts of Signals, Next: Standard Signals, Up: Signal Handling - -Basic Concepts of Signals -========================= - - This section explains basic concepts of how signals are generated, -what happens after a signal is delivered, and how programs can handle -signals. - -* Menu: - -* Kinds of Signals:: Some examples of what can cause a signal. -* Signal Generation:: Concepts of why and how signals occur. -* Delivery of Signal:: Concepts of what a signal does to the - process. - - -File: libc.info, Node: Kinds of Signals, Next: Signal Generation, Up: Concepts of Signals - -Some Kinds of Signals ---------------------- - - A signal reports the occurrence of an exceptional event. These are -some of the events that can cause (or "generate", or "raise") a signal: - - * A program error such as dividing by zero or issuing an address - outside the valid range. - - * A user request to interrupt or terminate the program. Most - environments are set up to let a user suspend the program by - typing `C-z', or terminate it with `C-c'. Whatever key sequence - is used, the operating system sends the proper signal to interrupt - the process. - - * The termination of a child process. - - * Expiration of a timer or alarm. - - * A call to `kill' or `raise' by the same process. - - * A call to `kill' from another process. Signals are a limited but - useful form of interprocess communication. - - * An attempt to perform an I/O operation that cannot be done. - Examples are reading from a pipe that has no writer (*note Pipes - and FIFOs::), and reading or writing to a terminal in certain - situations (*note Job Control::). - - Each of these kinds of events (excepting explicit calls to `kill' -and `raise') generates its own particular kind of signal. The various -kinds of signals are listed and described in detail in *Note Standard -Signals::. - - -File: libc.info, Node: Signal Generation, Next: Delivery of Signal, Prev: Kinds of Signals, Up: Concepts of Signals - -Concepts of Signal Generation ------------------------------ - - In general, the events that generate signals fall into three major -categories: errors, external events, and explicit requests. - - An error means that a program has done something invalid and cannot -continue execution. But not all kinds of errors generate signals--in -fact, most do not. For example, opening a nonexistent file is an error, -but it does not raise a signal; instead, `open' returns `-1'. In -general, errors that are necessarily associated with certain library -functions are reported by returning a value that indicates an error. -The errors which raise signals are those which can happen anywhere in -the program, not just in library calls. These include division by zero -and invalid memory addresses. - - An external event generally has to do with I/O or other processes. -These include the arrival of input, the expiration of a timer, and the -termination of a child process. - - An explicit request means the use of a library function such as -`kill' whose purpose is specifically to generate a signal. - - Signals may be generated "synchronously" or "asynchronously". A -synchronous signal pertains to a specific action in the program, and is -delivered (unless blocked) during that action. Most errors generate -signals synchronously, and so do explicit requests by a process to -generate a signal for that same process. On some machines, certain -kinds of hardware errors (usually floating-point exceptions) are not -reported completely synchronously, but may arrive a few instructions -later. - - Asynchronous signals are generated by events outside the control of -the process that receives them. These signals arrive at unpredictable -times during execution. External events generate signals -asynchronously, and so do explicit requests that apply to some other -process. - - A given type of signal is either typically synchronous or typically -asynchronous. For example, signals for errors are typically synchronous -because errors generate signals synchronously. But any type of signal -can be generated synchronously or asynchronously with an explicit -request. - - -File: libc.info, Node: Delivery of Signal, Prev: Signal Generation, Up: Concepts of Signals - -How Signals Are Delivered -------------------------- - - When a signal is generated, it becomes "pending". Normally it -remains pending for just a short period of time and then is "delivered" -to the process that was signaled. However, if that kind of signal is -currently "blocked", it may remain pending indefinitely--until signals -of that kind are "unblocked". Once unblocked, it will be delivered -immediately. *Note Blocking Signals::. - - When the signal is delivered, whether right away or after a long -delay, the "specified action" for that signal is taken. For certain -signals, such as `SIGKILL' and `SIGSTOP', the action is fixed, but for -most signals, the program has a choice: ignore the signal, specify a -"handler function", or accept the "default action" for that kind of -signal. The program specifies its choice using functions such as -`signal' or `sigaction' (*note Signal Actions::). We sometimes say -that a handler "catches" the signal. While the handler is running, -that particular signal is normally blocked. - - If the specified action for a kind of signal is to ignore it, then -any such signal which is generated is discarded immediately. This -happens even if the signal is also blocked at the time. A signal -discarded in this way will never be delivered, not even if the program -subsequently specifies a different action for that kind of signal and -then unblocks it. - - If a signal arrives which the program has neither handled nor -ignored, its "default action" takes place. Each kind of signal has its -own default action, documented below (*note Standard Signals::). For -most kinds of signals, the default action is to terminate the process. -For certain kinds of signals that represent "harmless" events, the -default action is to do nothing. - - When a signal terminates a process, its parent process can determine -the cause of termination by examining the termination status code -reported by the `wait' or `waitpid' functions. (This is discussed in -more detail in *Note Process Completion::.) The information it can get -includes the fact that termination was due to a signal and the kind of -signal involved. If a program you run from a shell is terminated by a -signal, the shell typically prints some kind of error message. - - The signals that normally represent program errors have a special -property: when one of these signals terminates the process, it also -writes a "core dump file" which records the state of the process at the -time of termination. You can examine the core dump with a debugger to -investigate what caused the error. - - If you raise a "program error" signal by explicit request, and this -terminates the process, it makes a core dump file just as if the signal -had been due directly to an error. - - -File: libc.info, Node: Standard Signals, Next: Signal Actions, Prev: Concepts of Signals, Up: Signal Handling - -Standard Signals -================ - - This section lists the names for various standard kinds of signals -and describes what kind of event they mean. Each signal name is a macro -which stands for a positive integer--the "signal number" for that kind -of signal. Your programs should never make assumptions about the -numeric code for a particular kind of signal, but rather refer to them -always by the names defined here. This is because the number for a -given kind of signal can vary from system to system, but the meanings of -the names are standardized and fairly uniform. - - The signal names are defined in the header file `signal.h'. - - - Macro: int NSIG - The value of this symbolic constant is the total number of signals - defined. Since the signal numbers are allocated consecutively, - `NSIG' is also one greater than the largest defined signal number. - -* Menu: - -* Program Error Signals:: Used to report serious program errors. -* Termination Signals:: Used to interrupt and/or terminate the - program. -* Alarm Signals:: Used to indicate expiration of timers. -* Asynchronous I/O Signals:: Used to indicate input is available. -* Job Control Signals:: Signals used to support job control. -* Operation Error Signals:: Used to report operational system errors. -* Miscellaneous Signals:: Miscellaneous Signals. -* Signal Messages:: Printing a message describing a signal. - diff -u -udbrN glibc-2.3.2/manual/libc.info-39 glibc-2.3.2-200304020432/manual/libc.info-39 --- glibc-2.3.2/manual/libc.info-39 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-39 Thu Jan 1 01:00:00 1970 @@ -1,1212 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

In general, -all of these signals are indications that your program is seriously -broken in some way, and there's usually no way to continue the -computation which encountered the error. - - Some programs handle program error signals in order to tidy up before -terminating; for example, programs that turn off echoing of terminal -input should handle program error signals in order to turn echoing back -on. The handler should end by specifying the default action for the -signal that happened and then reraising it; this will cause the program -to terminate with that signal, as if it had not had a handler. (*Note -Termination in Handler::.) - - Termination is the sensible ultimate outcome from a program error in -most programs. However, programming systems such as Lisp that can load -compiled user programs might need to keep executing even if a user -program incurs an error. These programs have handlers which use -`longjmp' to return control to the command level. - - The default action for all of these signals is to cause the process -to terminate. If you block or ignore these signals or establish -handlers for them that return normally, your program will probably -break horribly when such signals happen, unless they are generated by -`raise' or `kill' instead of a real error. - - When one of these program error signals terminates a process, it also -writes a "core dump file" which records the state of the process at the -time of termination. The core dump file is named `core' and is written -in whichever directory is current in the process at the time. (On the -GNU system, you can specify the file name for core dumps with the -environment variable `COREFILE'.) The purpose of core dump files is so -that you can examine them with a debugger to investigate what caused -the error. - - - Macro: int SIGFPE - The `SIGFPE' signal reports a fatal arithmetic error. Although the - name is derived from "floating-point exception", this signal - actually covers all arithmetic errors, including division by zero - and overflow. If a program stores integer data in a location - which is then used in a floating-point operation, this often - causes an "invalid operation" exception, because the processor - cannot recognize the data as a floating-point number. - - Actual floating-point exceptions are a complicated subject because - there are many types of exceptions with subtly different meanings, - and the `SIGFPE' signal doesn't distinguish between them. The - `IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std - 754-1985 and ANSI/IEEE Std 854-1987)' defines various - floating-point exceptions and requires conforming computer systems - to report their occurrences. However, this standard does not - specify how the exceptions are reported, or what kinds of handling - and control the operating system can offer to the programmer. - - BSD systems provide the `SIGFPE' handler with an extra argument that -distinguishes various causes of the exception. In order to access this -argument, you must define the handler to accept two arguments, which -means you must cast it to a one-argument function type in order to -establish the handler. The GNU library does provide this extra -argument, but the value is meaningful only on operating systems that -provide the information (BSD systems and GNU systems). - -`FPE_INTOVF_TRAP' - Integer overflow (impossible in a C program unless you enable - overflow trapping in a hardware-specific fashion). - -`FPE_INTDIV_TRAP' - Integer division by zero. - -`FPE_SUBRNG_TRAP' - Subscript-range (something that C programs never check for). - -`FPE_FLTOVF_TRAP' - Floating overflow trap. - -`FPE_FLTDIV_TRAP' - Floating/decimal division by zero. - -`FPE_FLTUND_TRAP' - Floating underflow trap. (Trapping on floating underflow is not - normally enabled.) - -`FPE_DECOVF_TRAP' - Decimal overflow trap. (Only a few machines have decimal - arithmetic and C never uses it.) - - - Macro: int SIGILL - The name of this signal is derived from "illegal instruction"; it - usually means your program is trying to execute garbage or a - privileged instruction. Since the C compiler generates only valid - instructions, `SIGILL' typically indicates that the executable - file is corrupted, or that you are trying to execute data. Some - common ways of getting into the latter situation are by passing an - invalid object where a pointer to a function was expected, or by - writing past the end of an automatic array (or similar problems - with pointers to automatic variables) and corrupting other data on - the stack such as the return address of a stack frame. - - `SIGILL' can also be generated when the stack overflows, or when - the system has trouble running the handler for a signal. - - - Macro: int SIGSEGV - This signal is generated when a program tries to read or write - outside the memory that is allocated for it, or to write memory - that can only be read. (Actually, the signals only occur when the - program goes far enough outside to be detected by the system's - memory protection mechanism.) The name is an abbreviation for - "segmentation violation". - - Common ways of getting a `SIGSEGV' condition include dereferencing - a null or uninitialized pointer, or when you use a pointer to step - through an array, but fail to check for the end of the array. It - varies among systems whether dereferencing a null pointer generates - `SIGSEGV' or `SIGBUS'. - - - Macro: int SIGBUS - This signal is generated when an invalid pointer is dereferenced. - Like `SIGSEGV', this signal is typically the result of - dereferencing an uninitialized pointer. The difference between - the two is that `SIGSEGV' indicates an invalid access to valid - memory, while `SIGBUS' indicates an access to an invalid address. - In particular, `SIGBUS' signals often result from dereferencing a - misaligned pointer, such as referring to a four-word integer at an - address not divisible by four. (Each kind of computer has its own - requirements for address alignment.) - - The name of this signal is an abbreviation for "bus error". - - - Macro: int SIGABRT - This signal indicates an error detected by the program itself and - reported by calling `abort'. *Note Aborting a Program::. - - - Macro: int SIGIOT - Generated by the PDP-11 "iot" instruction. On most machines, this - is just another name for `SIGABRT'. - - - Macro: int SIGTRAP - Generated by the machine's breakpoint instruction, and possibly - other trap instructions. This signal is used by debuggers. Your - program will probably only see `SIGTRAP' if it is somehow - executing bad instructions. - - - Macro: int SIGEMT - Emulator trap; this results from certain unimplemented instructions - which might be emulated in software, or the operating system's - failure to properly emulate them. - - - Macro: int SIGSYS - Bad system call; that is to say, the instruction to trap to the - operating system was executed, but the code number for the system - call to perform was invalid. - - -File: libc.info, Node: Termination Signals, Next: Alarm Signals, Prev: Program Error Signals, Up: Standard Signals - -Termination Signals -------------------- - - These signals are all used to tell a process to terminate, in one way -or another. They have different names because they're used for slightly -different purposes, and programs might want to handle them differently. - - The reason for handling these signals is usually so your program can -tidy up as appropriate before actually terminating. For example, you -might want to save state information, delete temporary files, or restore -the previous terminal modes. Such a handler should end by specifying -the default action for the signal that happened and then reraising it; -this will cause the program to terminate with that signal, as if it had -not had a handler. (*Note Termination in Handler::.) - - The (obvious) default action for all of these signals is to cause the -process to terminate. - - - Macro: int SIGTERM - The `SIGTERM' signal is a generic signal used to cause program - termination. Unlike `SIGKILL', this signal can be blocked, - handled, and ignored. It is the normal way to politely ask a - program to terminate. - - The shell command `kill' generates `SIGTERM' by default. - - - Macro: int SIGINT - The `SIGINT' ("program interrupt") signal is sent when the user - types the INTR character (normally `C-c'). *Note Special - Characters::, for information about terminal driver support for - `C-c'. - - - Macro: int SIGQUIT - The `SIGQUIT' signal is similar to `SIGINT', except that it's - controlled by a different key--the QUIT character, usually - `C-\'--and produces a core dump when it terminates the process, - just like a program error signal. You can think of this as a - program error condition "detected" by the user. - - *Note Program Error Signals::, for information about core dumps. - *Note Special Characters::, for information about terminal driver - support. - - Certain kinds of cleanups are best omitted in handling `SIGQUIT'. - For example, if the program creates temporary files, it should - handle the other termination requests by deleting the temporary - files. But it is better for `SIGQUIT' not to delete them, so that - the user can examine them in conjunction with the core dump. - - - Macro: int SIGKILL - The `SIGKILL' signal is used to cause immediate program - termination. It cannot be handled or ignored, and is therefore - always fatal. It is also not possible to block this signal. - - This signal is usually generated only by explicit request. Since - it cannot be handled, you should generate it only as a last - resort, after first trying a less drastic method such as `C-c' or - `SIGTERM'. If a process does not respond to any other termination - signals, sending it a `SIGKILL' signal will almost always cause it - to go away. - - In fact, if `SIGKILL' fails to terminate a process, that by itself - constitutes an operating system bug which you should report. - - The system will generate `SIGKILL' for a process itself under some - unusual conditions where the program cannot possibly continue to - run (even to run a signal handler). - - - Macro: int SIGHUP - The `SIGHUP' ("hang-up") signal is used to report that the user's - terminal is disconnected, perhaps because a network or telephone - connection was broken. For more information about this, see *Note - Control Modes::. - - This signal is also used to report the termination of the - controlling process on a terminal to jobs associated with that - session; this termination effectively disconnects all processes in - the session from the controlling terminal. For more information, - see *Note Termination Internals::. - - -File: libc.info, Node: Alarm Signals, Next: Asynchronous I/O Signals, Prev: Termination Signals, Up: Standard Signals - -Alarm Signals -------------- - - These signals are used to indicate the expiration of timers. *Note -Setting an Alarm::, for information about functions that cause these -signals to be sent. - - The default behavior for these signals is to cause program -termination. This default is rarely useful, but no other default would -be useful; most of the ways of using these signals would require -handler functions in any case. - - - Macro: int SIGALRM - This signal typically indicates expiration of a timer that - measures real or clock time. It is used by the `alarm' function, - for example. - - - Macro: int SIGVTALRM - This signal typically indicates expiration of a timer that - measures CPU time used by the current process. The name is an - abbreviation for "virtual time alarm". - - - Macro: int SIGPROF - This signal typically indicates expiration of a timer that measures - both CPU time used by the current process, and CPU time expended on - behalf of the process by the system. Such a timer is used to - implement code profiling facilities, hence the name of this signal. - - -File: libc.info, Node: Asynchronous I/O Signals, Next: Job Control Signals, Prev: Alarm Signals, Up: Standard Signals - -Asynchronous I/O Signals ------------------------- - - The signals listed in this section are used in conjunction with -asynchronous I/O facilities. You have to take explicit action by -calling `fcntl' to enable a particular file descriptor to generate -these signals (*note Interrupt Input::). The default action for these -signals is to ignore them. - - - Macro: int SIGIO - This signal is sent when a file descriptor is ready to perform - input or output. - - On most operating systems, terminals and sockets are the only - kinds of files that can generate `SIGIO'; other kinds, including - ordinary files, never generate `SIGIO' even if you ask them to. - - In the GNU system `SIGIO' will always be generated properly if you - successfully set asynchronous mode with `fcntl'. - - - Macro: int SIGURG - This signal is sent when "urgent" or out-of-band data arrives on a - socket. *Note Out-of-Band Data::. - - - Macro: int SIGPOLL - This is a System V signal name, more or less similar to `SIGIO'. - It is defined only for compatibility. - - -File: libc.info, Node: Job Control Signals, Next: Operation Error Signals, Prev: Asynchronous I/O Signals, Up: Standard Signals - -Job Control Signals -------------------- - - These signals are used to support job control. If your system -doesn't support job control, then these macros are defined but the -signals themselves can't be raised or handled. - - You should generally leave these signals alone unless you really -understand how job control works. *Note Job Control::. - - - Macro: int SIGCHLD - This signal is sent to a parent process whenever one of its child - processes terminates or stops. - - The default action for this signal is to ignore it. If you - establish a handler for this signal while there are child - processes that have terminated but not reported their status via - `wait' or `waitpid' (*note Process Completion::), whether your new - handler applies to those processes or not depends on the - particular operating system. - - - Macro: int SIGCLD - This is an obsolete name for `SIGCHLD'. - - - Macro: int SIGCONT - You can send a `SIGCONT' signal to a process to make it continue. - This signal is special--it always makes the process continue if it - is stopped, before the signal is delivered. The default behavior - is to do nothing else. You cannot block this signal. You can set - a handler, but `SIGCONT' always makes the process continue - regardless. - - Most programs have no reason to handle `SIGCONT'; they simply - resume execution without realizing they were ever stopped. You - can use a handler for `SIGCONT' to make a program do something - special when it is stopped and continued--for example, to reprint - a prompt when it is suspended while waiting for input. - - - Macro: int SIGSTOP - The `SIGSTOP' signal stops the process. It cannot be handled, - ignored, or blocked. - - - Macro: int SIGTSTP - The `SIGTSTP' signal is an interactive stop signal. Unlike - `SIGSTOP', this signal can be handled and ignored. - - Your program should handle this signal if you have a special need - to leave files or system tables in a secure state when a process is - stopped. For example, programs that turn off echoing should handle - `SIGTSTP' so they can turn echoing back on before stopping. - - This signal is generated when the user types the SUSP character - (normally `C-z'). For more information about terminal driver - support, see *Note Special Characters::. - - - Macro: int SIGTTIN - A process cannot read from the user's terminal while it is running - as a background job. When any process in a background job tries to - read from the terminal, all of the processes in the job are sent a - `SIGTTIN' signal. The default action for this signal is to stop - the process. For more information about how this interacts with - the terminal driver, see *Note Access to the Terminal::. - - - Macro: int SIGTTOU - This is similar to `SIGTTIN', but is generated when a process in a - background job attempts to write to the terminal or set its modes. - Again, the default action is to stop the process. `SIGTTOU' is - only generated for an attempt to write to the terminal if the - `TOSTOP' output mode is set; *note Output Modes::. - - While a process is stopped, no more signals can be delivered to it -until it is continued, except `SIGKILL' signals and (obviously) -`SIGCONT' signals. The signals are marked as pending, but not -delivered until the process is continued. The `SIGKILL' signal always -causes termination of the process and can't be blocked, handled or -ignored. You can ignore `SIGCONT', but it always causes the process to -be continued anyway if it is stopped. Sending a `SIGCONT' signal to a -process causes any pending stop signals for that process to be -discarded. Likewise, any pending `SIGCONT' signals for a process are -discarded when it receives a stop signal. - - When a process in an orphaned process group (*note Orphaned Process -Groups::) receives a `SIGTSTP', `SIGTTIN', or `SIGTTOU' signal and does -not handle it, the process does not stop. Stopping the process would -probably not be very useful, since there is no shell program that will -notice it stop and allow the user to continue it. What happens instead -depends on the operating system you are using. Some systems may do -nothing; others may deliver another signal instead, such as `SIGKILL' -or `SIGHUP'. In the GNU system, the process dies with `SIGKILL'; this -avoids the problem of many stopped, orphaned processes lying around the -system. - - -File: libc.info, Node: Operation Error Signals, Next: Miscellaneous Signals, Prev: Job Control Signals, Up: Standard Signals - -Operation Error Signals ------------------------ - - These signals are used to report various errors generated by an -operation done by the program. They do not necessarily indicate a -programming error in the program, but an error that prevents an -operating system call from completing. The default action for all of -them is to cause the process to terminate. - - - Macro: int SIGPIPE - Broken pipe. If you use pipes or FIFOs, you have to design your - application so that one process opens the pipe for reading before - another starts writing. If the reading process never starts, or - terminates unexpectedly, writing to the pipe or FIFO raises a - `SIGPIPE' signal. If `SIGPIPE' is blocked, handled or ignored, - the offending call fails with `EPIPE' instead. - - Pipes and FIFO special files are discussed in more detail in *Note - Pipes and FIFOs::. - - Another cause of `SIGPIPE' is when you try to output to a socket - that isn't connected. *Note Sending Data::. - - - Macro: int SIGLOST - Resource lost. This signal is generated when you have an advisory - lock on an NFS file, and the NFS server reboots and forgets about - your lock. - - In the GNU system, `SIGLOST' is generated when any server program - dies unexpectedly. It is usually fine to ignore the signal; - whatever call was made to the server that died just returns an - error. - - - Macro: int SIGXCPU - CPU time limit exceeded. This signal is generated when the process - exceeds its soft resource limit on CPU time. *Note Limits on - Resources::. - - - Macro: int SIGXFSZ - File size limit exceeded. This signal is generated when the - process attempts to extend a file so it exceeds the process's soft - resource limit on file size. *Note Limits on Resources::. - - -File: libc.info, Node: Miscellaneous Signals, Next: Signal Messages, Prev: Operation Error Signals, Up: Standard Signals - -Miscellaneous Signals ---------------------- - - These signals are used for various other purposes. In general, they -will not affect your program unless it explicitly uses them for -something. - - - Macro: int SIGUSR1 - - Macro: int SIGUSR2 - The `SIGUSR1' and `SIGUSR2' signals are set aside for you to use - any way you want. They're useful for simple interprocess - communication, if you write a signal handler for them in the - program that receives the signal. - - There is an example showing the use of `SIGUSR1' and `SIGUSR2' in - *Note Signaling Another Process::. - - The default action is to terminate the process. - - - Macro: int SIGWINCH - Window size change. This is generated on some systems (including - GNU) when the terminal driver's record of the number of rows and - columns on the screen is changed. The default action is to ignore - it. - - If a program does full-screen display, it should handle `SIGWINCH'. - When the signal arrives, it should fetch the new screen size and - reformat its display accordingly. - - - Macro: int SIGINFO - Information request. In 4.4 BSD and the GNU system, this signal - is sent to all the processes in the foreground process group of - the controlling terminal when the user types the STATUS character - in canonical mode; *note Signal Characters::. - - If the process is the leader of the process group, the default - action is to print some status information about the system and - what the process is doing. Otherwise the default is to do nothing. - - -File: libc.info, Node: Signal Messages, Prev: Miscellaneous Signals, Up: Standard Signals - -Signal Messages ---------------- - - We mentioned above that the shell prints a message describing the -signal that terminated a child process. The clean way to print a -message describing a signal is to use the functions `strsignal' and -`psignal'. These functions use a signal number to specify which kind -of signal to describe. The signal number may come from the termination -status of a child process (*note Process Completion::) or it may come -from a signal handler in the same process. - - - Function: char * strsignal (int SIGNUM) - This function returns a pointer to a statically-allocated string - containing a message describing the signal SIGNUM.

It adds a colon and a space - character to separate the MESSAGE from the string corresponding to - SIGNUM. - - This function is a BSD feature, declared in the header file - `signal.h'. - - There is also an array `sys_siglist' which contains the messages for -the various signal codes. This array exists on BSD systems, unlike -`strsignal'. - - -File: libc.info, Node: Signal Actions, Next: Defining Handlers, Prev: Standard Signals, Up: Signal Handling - -Specifying Signal Actions -========================= - - The simplest way to change the action for a signal is to use the -`signal' function. You can specify a built-in action (such as to -ignore the signal), or you can "establish a handler". - - The GNU library also implements the more versatile `sigaction' -facility. This section describes both facilities and gives suggestions -on which to use when. - -* Menu: - -* Basic Signal Handling:: The simple `signal' function. -* Advanced Signal Handling:: The more powerful `sigaction' function. -* Signal and Sigaction:: How those two functions interact. -* Sigaction Function Example:: An example of using the sigaction function. -* Flags for Sigaction:: Specifying options for signal handling. -* Initial Signal Actions:: How programs inherit signal actions. - - -File: libc.info, Node: Basic Signal Handling, Next: Advanced Signal Handling, Up: Signal Actions - -Basic Signal Handling ---------------------- - - The `signal' function provides a simple interface for establishing -an action for a particular signal. The function and associated macros -are declared in the header file `signal.h'. - - - Data Type: sighandler_t - This is the type of signal handler functions. Signal handlers - take one integer argument specifying the signal number, and have - return type `void'. So, you should define handler functions like - this: - - void HANDLER (int `signum') { ... } - - The name `sighandler_t' for this data type is a GNU extension. - - - Function: sighandler_t signal (int SIGNUM, sighandler_t ACTION) - The `signal' function establishes ACTION as the action for the - signal SIGNUM. - - The first argument, SIGNUM, identifies the signal whose behavior - you want to control, and should be a signal number. The proper - way to specify a signal number is with one of the symbolic signal - names (*note Standard Signals::)--don't use an explicit number, - because the numerical code for a given kind of signal may vary - from operating system to operating system. - - The second argument, ACTION, specifies the action to use for the - signal SIGNUM. This can be one of the following: - - `SIG_DFL' - `SIG_DFL' specifies the default action for the particular - signal. The default actions for various kinds of signals are - stated in *Note Standard Signals::. - - `SIG_IGN' - `SIG_IGN' specifies that the signal should be ignored. - - Your program generally should not ignore signals that - represent serious events or that are normally used to request - termination. You cannot ignore the `SIGKILL' or `SIGSTOP' - signals at all. You can ignore program error signals like - `SIGSEGV', but ignoring the error won't enable the program to - continue executing meaningfully. Ignoring user requests such - as `SIGINT', `SIGQUIT', and `SIGTSTP' is unfriendly. - - When you do not wish signals to be delivered during a certain - part of the program, the thing to do is to block them, not - ignore them. *Note Blocking Signals::. - - `HANDLER' - Supply the address of a handler function in your program, to - specify running this handler as the way to deliver the signal. - - For more information about defining signal handler functions, - see *Note Defining Handlers::. - - If you set the action for a signal to `SIG_IGN', or if you set it - to `SIG_DFL' and the default action is to ignore that signal, then - any pending signals of that type are discarded (even if they are - blocked). Discarding the pending signals means that they will - never be delivered, not even if you subsequently specify another - action and unblock this kind of signal. - - The `signal' function returns the action that was previously in - effect for the specified SIGNUM. You can save this value and - restore it later by calling `signal' again. - - If `signal' can't honor the request, it returns `SIG_ERR' instead. - The following `errno' error conditions are defined for this - function: - - `EINVAL' - You specified an invalid SIGNUM; or you tried to ignore or - provide a handler for `SIGKILL' or `SIGSTOP'. - - *Compatibility Note:* A problem encountered when working with the -`signal' function is that it has different semantics on BSD and SVID -systems. The difference is that on SVID systems the signal handler is -deinstalled after signal delivery. On BSD systems the handler must be -explicitly deinstalled. In the GNU C Library we use the BSD version by -default. To use the SVID version you can either use the function -`sysv_signal' (see below) or use the `_XOPEN_SOURCE' feature select -macro (*note Feature Test Macros::). In general, use of these -functions should be avoided because of compatibility problems. It is -better to use `sigaction' if it is available since the results are much -more reliable. - - Here is a simple example of setting up a handler to delete temporary -files when certain fatal signals happen: - - #include - - void - termination_handler (int signum) - { - struct temp_file *p; - - for (p = temp_file_list; p; p = p->next) - unlink (p->name); - } - - int - main (void) - { - ... - if (signal (SIGINT, termination_handler) == SIG_IGN) - signal (SIGINT, SIG_IGN); - if (signal (SIGHUP, termination_handler) == SIG_IGN) - signal (SIGHUP, SIG_IGN); - if (signal (SIGTERM, termination_handler) == SIG_IGN) - signal (SIGTERM, SIG_IGN); - ... - } - -Note that if a given signal was previously set to be ignored, this code -avoids altering that setting. This is because non-job-control shells -often ignore certain signals when starting children, and it is important -for the children to respect this. - - We do not handle `SIGQUIT' or the program error signals in this -example because these are designed to provide information for debugging -(a core dump), and the temporary files may give useful information. - - - Function: sighandler_t sysv_signal (int SIGNUM, sighandler_t ACTION) - The `sysv_signal' implements the behavior of the standard `signal' - function as found on SVID systems. The difference to BSD systems - is that the handler is deinstalled after a delivery of a signal. - - *Compatibility Note:* As said above for `signal', this function - should be avoided when possible. `sigaction' is the preferred - method. - - - Function: sighandler_t ssignal (int SIGNUM, sighandler_t ACTION) - The `ssignal' function does the same thing as `signal'; it is - provided only for compatibility with SVID. - - - Macro: sighandler_t SIG_ERR - The value of this macro is used as the return value from `signal' - to indicate an error. - - -File: libc.info, Node: Advanced Signal Handling, Next: Signal and Sigaction, Prev: Basic Signal Handling, Up: Signal Actions - -Advanced Signal Handling ------------------------- - - The `sigaction' function has the same basic effect as `signal': to -specify how a signal should be handled by the process. However, -`sigaction' offers more control, at the expense of more complexity. In -particular, `sigaction' allows you to specify additional flags to -control when the signal is generated and how the handler is invoked. - - The `sigaction' function is declared in `signal.h'. - - - Data Type: struct sigaction - Structures of type `struct sigaction' are used in the `sigaction' - function to specify all the information about how to handle a - particular signal. This structure contains at least the following - members: - - `sighandler_t sa_handler' - This is used in the same way as the ACTION argument to the - `signal' function. The value can be `SIG_DFL', `SIG_IGN', or - a function pointer. *Note Basic Signal Handling::. - - `sigset_t sa_mask' - This specifies a set of signals to be blocked while the - handler runs. Blocking is explained in *Note Blocking for - Handler::. Note that the signal that was delivered is - automatically blocked by default before its handler is - started; this is true regardless of the value in `sa_mask'. - If you want that signal not to be blocked within its handler, - you must write code in the handler to unblock it. - - `int sa_flags' - This specifies various flags which can affect the behavior of - the signal. These are described in more detail in *Note - Flags for Sigaction::. - - - Function: int sigaction (int SIGNUM, const struct sigaction - *restrict ACTION, struct sigaction *restrict OLD-ACTION) - The ACTION argument is used to set up a new action for the signal - SIGNUM, while the OLD-ACTION argument is used to return - information about the action previously associated with this - symbol. (In other words, OLD-ACTION has the same purpose as the - `signal' function's return value--you can check to see what the - old action in effect for the signal was, and restore it later if - you want.) - - Either ACTION or OLD-ACTION can be a null pointer. If OLD-ACTION - is a null pointer, this simply suppresses the return of - information about the old action. If ACTION is a null pointer, - the action associated with the signal SIGNUM is unchanged; this - allows you to inquire about how a signal is being handled without - changing that handling. - - The return value from `sigaction' is zero if it succeeds, and `-1' - on failure. The following `errno' error conditions are defined - for this function: - - `EINVAL' - The SIGNUM argument is not valid, or you are trying to trap - or ignore `SIGKILL' or `SIGSTOP'. - - -File: libc.info, Node: Signal and Sigaction, Next: Sigaction Function Example, Prev: Advanced Signal Handling, Up: Signal Actions - -Interaction of `signal' and `sigaction' ---------------------------------------- - - It's possible to use both the `signal' and `sigaction' functions -within a single program, but you have to be careful because they can -interact in slightly strange ways. - - The `sigaction' function specifies more information than the -`signal' function, so the return value from `signal' cannot express the -full range of `sigaction' possibilities. Therefore, if you use -`signal' to save and later reestablish an action, it may not be able to -reestablish properly a handler that was established with `sigaction'. - - To avoid having problems as a result, always use `sigaction' to save -and restore a handler if your program uses `sigaction' at all. Since -`sigaction' is more general, it can properly save and reestablish any -action, regardless of whether it was established originally with -`signal' or `sigaction'. - - On some systems if you establish an action with `signal' and then -examine it with `sigaction', the handler address that you get may not -be the same as what you specified with `signal'. It may not even be -suitable for use as an action argument with `signal'. But you can rely -on using it as an argument to `sigaction'. This problem never happens -on the GNU system. - - So, you're better off using one or the other of the mechanisms -consistently within a single program. - - *Portability Note:* The basic `signal' function is a feature of -ISO C, while `sigaction' is part of the POSIX.1 standard. If you are -concerned about portability to non-POSIX systems, then you should use -the `signal' function instead. - - -File: libc.info, Node: Sigaction Function Example, Next: Flags for Sigaction, Prev: Signal and Sigaction, Up: Signal Actions - -`sigaction' Function Example ----------------------------- - - In *Note Basic Signal Handling::, we gave an example of establishing -a simple handler for termination signals using `signal'. Here is an -equivalent example using `sigaction': - - #include - - void - termination_handler (int signum) - { - struct temp_file *p; - - for (p = temp_file_list; p; p = p->next) - unlink (p->name); - } - - int - main (void) - { - ... - struct sigaction new_action, old_action; - - /* Set up the structure to specify the new action. */ - new_action.sa_handler = termination_handler; - sigemptyset (&new_action.sa_mask); - new_action.sa_flags = 0; - - sigaction (SIGINT, NULL, &old_action); - if (old_action.sa_handler != SIG_IGN) - sigaction (SIGINT, &new_action, NULL); - sigaction (SIGHUP, NULL, &old_action); - if (old_action.sa_handler != SIG_IGN) - sigaction (SIGHUP, &new_action, NULL); - sigaction (SIGTERM, NULL, &old_action); - if (old_action.sa_handler != SIG_IGN) - sigaction (SIGTERM, &new_action, NULL); - ... - } - - The program just loads the `new_action' structure with the desired -parameters and passes it in the `sigaction' call. The usage of -`sigemptyset' is described later; see *Note Blocking Signals::. - - As in the example using `signal', we avoid handling signals -previously set to be ignored. Here we can avoid altering the signal -handler even momentarily, by using the feature of `sigaction' that lets -us examine the current action without specifying a new one. - - Here is another example. It retrieves information about the current -action for `SIGINT' without changing that action. - - struct sigaction query_action; - - if (sigaction (SIGINT, NULL, &query_action) < 0) - /* `sigaction' returns -1 in case of error. */ - else if (query_action.sa_handler == SIG_DFL) - /* `SIGINT' is handled in the default, fatal manner. */ - else if (query_action.sa_handler == SIG_IGN) - /* `SIGINT' is ignored. */ - else - /* A programmer-defined signal handler is in effect. */ - - -File: libc.info, Node: Flags for Sigaction, Next: Initial Signal Actions, Prev: Sigaction Function Example, Up: Signal Actions - -Flags for `sigaction' ---------------------- - - The `sa_flags' member of the `sigaction' structure is a catch-all -for special features. Most of the time, `SA_RESTART' is a good value -to use for this field. - - The value of `sa_flags' is interpreted as a bit mask. Thus, you -should choose the flags you want to set, OR those flags together, and -store the result in the `sa_flags' member of your `sigaction' structure. - - Each signal number has its own set of flags. Each call to -`sigaction' affects one particular signal number, and the flags that -you specify apply only to that particular signal. - - In the GNU C library, establishing a handler with `signal' sets all -the flags to zero except for `SA_RESTART', whose value depends on the -settings you have made with `siginterrupt'. *Note Interrupted -Primitives::, to see what this is about. - - These macros are defined in the header file `signal.h'. - - - Macro: int SA_NOCLDSTOP - This flag is meaningful only for the `SIGCHLD' signal. When the - flag is set, the system delivers the signal for a terminated child - process but not for one that is stopped. By default, `SIGCHLD' is - delivered for both terminated children and stopped children. - - Setting this flag for a signal other than `SIGCHLD' has no effect. - - - Macro: int SA_ONSTACK - If this flag is set for a particular signal number, the system - uses the signal stack when delivering that kind of signal. *Note - Signal Stack::. If a signal with this flag arrives and you have - not set a signal stack, the system terminates the program with - `SIGILL'. - - - Macro: int SA_RESTART - This flag controls what happens when a signal is delivered during - certain primitives (such as `open', `read' or `write'), and the - signal handler returns normally. There are two alternatives: the - library function can resume, or it can return failure with error - code `EINTR'. - - The choice is controlled by the `SA_RESTART' flag for the - particular kind of signal that was delivered. If the flag is set, - returning from a handler resumes the library function. If the - flag is clear, returning from a handler makes the function fail. - *Note Interrupted Primitives::. - - -File: libc.info, Node: Initial Signal Actions, Prev: Flags for Sigaction, Up: Signal Actions - -Initial Signal Actions ----------------------- - - When a new process is created (*note Creating a Process::), it -inherits handling of signals from its parent process. However, when -you load a new process image using the `exec' function (*note Executing -a File::), any signals that you've defined your own handlers for revert -to their `SIG_DFL' handling. (If you think about it a little, this -makes sense; the handler functions from the old program are specific to -that program, and aren't even present in the address space of the new -program image.) Of course, the new program can establish its own -handlers. - - When a program is run by a shell, the shell normally sets the initial -actions for the child process to `SIG_DFL' or `SIG_IGN', as -appropriate. It's a good idea to check to make sure that the shell has -not set up an initial action of `SIG_IGN' before you establish your own -signal handlers. - - Here is an example of how to establish a handler for `SIGHUP', but -not if `SIGHUP' is currently ignored: - - ... - struct sigaction temp; - - sigaction (SIGHUP, NULL, &temp); - - if (temp.sa_handler != SIG_IGN) - { - temp.sa_handler = handle_sighup; - sigemptyset (&temp.sa_mask); - sigaction (SIGHUP, &temp, NULL); - } - - -File: libc.info, Node: Defining Handlers, Next: Interrupted Primitives, Prev: Signal Actions, Up: Signal Handling - -Defining Signal Handlers -======================== - - This section describes how to write a signal handler function that -can be established with the `signal' or `sigaction' functions. - - A signal handler is just a function that you compile together with -the rest of the program. Instead of directly invoking the function, -you use `signal' or `sigaction' to tell the operating system to call it -when a signal arrives. This is known as "establishing" the handler. -*Note Signal Actions::. - - There are two basic strategies you can use in signal handler -functions: - - * You can have the handler function note that the signal arrived by - tweaking some global data structures, and then return normally. - - * You can have the handler function terminate the program or transfer - control to a point where it can recover from the situation that - caused the signal. - - You need to take special care in writing handler functions because -they can be called asynchronously. That is, a handler might be called -at any point in the program, unpredictably. If two signals arrive -during a very short interval, one handler can run within another.

But a -handler for `SIGINT' might also return normally after setting a flag -that tells the program to exit at a convenient time. - - It is not safe to return normally from the handler for a program -error signal, because the behavior of the program when the handler -function returns is not defined after a program error. *Note Program -Error Signals::. - - Handlers that return normally must modify some global variable in -order to have any effect. Typically, the variable is one that is -examined periodically by the program during normal operation. Its data -type should be `sig_atomic_t' for reasons described in *Note Atomic -Data Access::. - - Here is a simple example of such a program.

We reactivate the signal's - default handling, which is to terminate the process. - We could just call `exit' or `abort', - but reraising the signal sets the return status - from the process correctly. */ - signal (sig, SIG_DFL); - raise (sig); - } - - -File: libc.info, Node: Longjmp in Handler, Next: Signals in Handler, Prev: Termination in Handler, Up: Defining Handlers - -Nonlocal Control Transfer in Handlers -------------------------------------- - - You can do a nonlocal transfer of control out of a signal handler -using the `setjmp' and `longjmp' facilities (*note Non-Local Exits::). - - When the handler does a nonlocal control transfer, the part of the -program that was running will not continue.

Neighboring chunks can be coalesced on a `free' no matter -what their size is. This makes the implementation suitable for all -kinds of allocation patterns without generally incurring high memory -waste through fragmentation. - - Very large blocks (much larger than a page) are allocated with -`mmap' (anonymous or via `/dev/zero') by this implementation. This has -the great advantage that these chunks are returned to the system -immediately when they are freed. Therefore, it cannot happen that a -large chunk becomes "locked" in between smaller ones and even after -calling `free' wastes memory.

That does not work -in BSD, however--BSD does not provide any way to free such blocks. - - - Function: void * memalign (size_t BOUNDARY, size_t SIZE) - The `memalign' function allocates a block of SIZE bytes whose - address is a multiple of BOUNDARY. The BOUNDARY must be a power - of two! The function `memalign' works by allocating a somewhat - larger block, and then returning an address within the block that - is on the specified boundary. - - - Function: int posix_memalign (void **MEMPTR, size_t ALIGNMENT, - size_t SIZE) - The `posix_memalign' function is similar to the `memalign' - function in that it returns a buffer of SIZE bytes aligned to a - multiple of ALIGNMENT. But it adds one requirement to the - parameter ALIGNMENT: the value must be a power of two multiple of - `sizeof (void *)'. - - If the function succeeds in allocation memory a pointer to the - allocated memory is returned in `*MEMPTR' and the return value is - zero. Otherwise the function returns an error value indicating - the problem. - - This function was introduced in POSIX 1003.1d. - - - Function: void * valloc (size_t SIZE) - Using `valloc' is like using `memalign' and passing the page size - as the value of the second argument.

This function is the general SVID/XPG interface, -defined in `malloc.h'. - - - Function: int mallopt (int PARAM, int VALUE) - When calling `mallopt', the PARAM argument specifies the parameter - to be set, and VALUE the new value to be set. Possible choices - for PARAM, as defined in `malloc.h', are: - - `M_TRIM_THRESHOLD' - This is the minimum size (in bytes) of the top-most, - releasable chunk that will cause `sbrk' to be called with a - negative argument in order to return memory to the system. - - `M_TOP_PAD' - This parameter determines the amount of extra memory to - obtain from the system when a call to `sbrk' is required. It - also specifies the number of bytes to retain when shrinking - the heap by calling `sbrk' with a negative argument. This - provides the necessary hysteresis in heap size such that - excessive amounts of system calls can be avoided. - - `M_MMAP_THRESHOLD' - All chunks larger than this value are allocated outside the - normal heap, using the `mmap' system call. This way it is - guaranteed that the memory for these chunks can be returned - to the system on `free'. Note that requests smaller than - this threshold might still be allocated via `mmap'. - - `M_MMAP_MAX' - The maximum number of chunks to allocate with `mmap'. - Setting this to zero disables all use of `mmap'. - - - -File: libc.info, Node: Heap Consistency Checking, Next: Hooks for Malloc, Prev: Malloc Tunable Parameters, Up: Unconstrained Allocation - -Heap Consistency Checking -......................... - - You can ask `malloc' to check the consistency of dynamic memory by -using the `mcheck' function. This function is a GNU extension, -declared in `mcheck.h'. - - - Function: int mcheck (void (*ABORTFN) (enum mcheck_status STATUS)) - Calling `mcheck' tells `malloc' to perform occasional consistency - checks. These will catch things such as writing past the end of a - block that was allocated with `malloc'. - - The ABORTFN argument is the function to call when an inconsistency - is found. If you supply a null pointer, then `mcheck' uses a - default function which prints a message and calls `abort' (*note - Aborting a Program::). The function you supply is called with one - argument, which says what sort of inconsistency was detected; its - type is described below. - - It is too late to begin allocation checking once you have allocated - anything with `malloc'. So `mcheck' does nothing in that case. - The function returns `-1' if you call it too late, and `0' - otherwise (when it is successful). - - The easiest way to arrange to call `mcheck' early enough is to use - the option `-lmcheck' when you link your program; then you don't - need to modify your program source at all. Alternatively you - might use a debugger to insert a call to `mcheck' whenever the - program is started, for example these gdb commands will - automatically call `mcheck' whenever the program starts: - - (gdb) break main - Breakpoint 1, main (argc=2, argv=0xbffff964) at whatever.c:10 - (gdb) command 1 - Type commands for when breakpoint 1 is hit, one per line. - End with a line saying just "end". - >call mcheck(0) - >continue - >end - (gdb) ... - - This will however only work if no initialization function of any - object involved calls any of the `malloc' functions since `mcheck' - must be called before the first such function. - - - - Function: enum mcheck_status mprobe (void *POINTER) - The `mprobe' function lets you explicitly check for inconsistencies - in a particular allocated block. You must have already called - `mcheck' at the beginning of the program, to do its occasional - checks; calling `mprobe' requests an additional consistency check - to be done at the time of the call. - - The argument POINTER must be a pointer returned by `malloc' or - `realloc'. `mprobe' returns a value that says what inconsistency, - if any, was found. The values are described below. - - - Data Type: enum mcheck_status - This enumerated type describes what kind of inconsistency was - detected in an allocated block, if any. Here are the possible - values: - - `MCHECK_DISABLED' - `mcheck' was not called before the first allocation. No - consistency checking can be done. - - `MCHECK_OK' - No inconsistency detected. - - `MCHECK_HEAD' - The data immediately before the block was modified. This - commonly happens when an array index or pointer is - decremented too far. - - `MCHECK_TAIL' - The data immediately after the block was modified. This - commonly happens when an array index or pointer is - incremented too far. - - `MCHECK_FREE' - The block was already freed. - - Another possibility to check for and guard against bugs in the use of -`malloc', `realloc' and `free' is to set the environment variable -`MALLOC_CHECK_'. When `MALLOC_CHECK_' is set, a special (less -efficient) implementation is used which is designed to be tolerant -against simple errors, such as double calls of `free' with the same -argument, or overruns of a single byte (off-by-one bugs). Not all such -errors can be protected against, however, and memory leaks can result. -If `MALLOC_CHECK_' is set to `0', any detected heap corruption is -silently ignored; if set to `1', a diagnostic is printed on `stderr'; -if set to `2', `abort' is called immediately. This can be useful -because otherwise a crash may happen much later, and the true cause for -the problem is then very hard to track down. - - There is one problem with `MALLOC_CHECK_': in SUID or SGID binaries -it could possibly be exploited since diverging from the normal programs -behavior it now writes something to the standard error descriptor. -Therefore the use of `MALLOC_CHECK_' is disabled by default for SUID -and SGID binaries. It can be enabled again by the system administrator -by adding a file `/etc/suid-debug' (the content is not important it -could be empty). - - So, what's the difference between using `MALLOC_CHECK_' and linking -with `-lmcheck'? `MALLOC_CHECK_' is orthogonal with respect to -`-lmcheck'. `-lmcheck' has been added for backward compatibility. -Both `MALLOC_CHECK_' and `-lmcheck' should uncover the same bugs - but -using `MALLOC_CHECK_' you don't need to recompile your application. - - -File: libc.info, Node: Hooks for Malloc, Next: Statistics of Malloc, Prev: Heap Consistency Checking, Up: Unconstrained Allocation - -Memory Allocation Hooks -....................... - - The GNU C library lets you modify the behavior of `malloc', -`realloc', and `free' by specifying appropriate hook functions.

Otherwise, your program -will get stuck in an infinite recursion. Before calling the function -recursively, one should make sure to restore all the hooks to their -previous value.

This - is a weak variable, so it can be overridden in the application - with a definition like the following: - - void (*__MALLOC_INITIALIZE_HOOK) (void) = my_init_hook; - - An issue to look out for is the time at which the malloc hook -functions can be safely installed. If the hook functions call the -malloc-related functions recursively, it is necessary that malloc has -already properly initialized itself at the time when `__malloc_hook' -etc. is assigned to. On the other hand, if the hook functions provide a -complete malloc implementation of their own, it is vital that the hooks -are assigned to _before_ the very first `malloc' call has completed, -because otherwise a chunk obtained from the ordinary, un-hooked malloc -may later be handed to `__free_hook', for example. - - In both cases, the problem can be solved by setting up the hooks from -within a user-defined function pointed to by -`__malloc_initialize_hook'--then the hooks will be set up safely at the -right time. - - Here is an example showing how to use `__malloc_hook' and -`__free_hook' properly.

Just imagine that you debug a program using `mtrace' and all -other programs used in the debugging session also trace their `malloc' -calls. The output file would be the same for all programs and thus is -unusable. Therefore one should call `mtrace' only if compiled for -debugging. A program could therefore start like this: - - #include - - int - main (int argc, char *argv[]) - { - #ifdef DEBUGGING - mtrace (); - #endif - ... - } - - This is all what is needed if you want to trace the calls during the -whole runtime of the program.

This structure has a small fixed size; it records the - status of the obstack and how to find the space in which objects - are allocated. It does not contain any of the objects themselves. - You should not try to access the contents of the structure - directly; use only the functions described in this chapter. - - You can declare variables of type `struct obstack' and use them as -obstacks, or you can allocate obstacks dynamically like any other kind -of object. Dynamic allocation of obstacks allows your program to have a -variable number of different stacks. (You can even allocate an obstack -structure in another obstack, but this is rarely useful.) - - All the functions that work with obstacks require you to specify -which obstack to use. You do this with a pointer of type `struct -obstack *'. In the following, we often say "an obstack" when strictly -speaking the object at hand is such a pointer. - - The objects in the obstack are packed into large blocks called -"chunks". The `struct obstack' structure points to a chain of the -chunks currently in use. - - The obstack library obtains a new chunk whenever you allocate an -object that won't fit in the previous chunk. Since the obstack library -manages chunks automatically, you don't need to pay much attention to -them, but you do need to supply a function which the obstack library -should use to get a chunk. Usually you supply a function which uses -`malloc' directly or indirectly. You must also supply a function to -free a chunk. These matters are described in the following section. - - -File: libc.info, Node: Preparing for Obstacks, Next: Allocation in an Obstack, Prev: Creating Obstacks, Up: Obstacks - -Preparing for Using Obstacks -............................ - - Each source file in which you plan to use the obstack functions must -include the header file `obstack.h', like this: - - #include - - Also, if the source file uses the macro `obstack_init', it must -declare or define two functions or macros that will be called by the -obstack library. One, `obstack_chunk_alloc', is used to allocate the -chunks of memory into which objects are packed. The other, -`obstack_chunk_free', is used to return chunks when the objects in them -are freed. These macros should appear before any use of obstacks in -the source file. - - Usually these are defined to use `malloc' via the intermediary -`xmalloc' (*note Unconstrained Allocation::). This is done with the -following pair of macro definitions: - - #define obstack_chunk_alloc xmalloc - #define obstack_chunk_free free - -Though the memory you get using obstacks really comes from `malloc', -using obstacks is faster because `malloc' is called less often, for -larger blocks of memory. *Note Obstack Chunks::, for full details. - - At run time, before the program can use a `struct obstack' object as -an obstack, it must initialize the obstack by calling `obstack_init'. - - - Function: int obstack_init (struct obstack *OBSTACK-PTR) - Initialize obstack OBSTACK-PTR for allocation of objects. This - function calls the obstack's `obstack_chunk_alloc' function. If - allocation of memory fails, the function pointed to by - `obstack_alloc_failed_handler' is called. The `obstack_init' - function always returns 1 (Compatibility notice: Former versions of - obstack returned 0 if allocation failed). - - Here are two examples of how to allocate the space for an obstack and -initialize it. First, an obstack that is a static variable: - - static struct obstack myobstack; - ... - obstack_init (&myobstack); - -Second, an obstack that is itself dynamically allocated: - - struct obstack *myobstack_ptr - = (struct obstack *) xmalloc (sizeof (struct obstack)); - - obstack_init (myobstack_ptr); - - - Variable: obstack_alloc_failed_handler - The value of this variable is a pointer to a function that - `obstack' uses when `obstack_chunk_alloc' fails to allocate - memory. The default action is to print a message and abort. You - should supply a function that either calls `exit' (*note Program - Termination::) or `longjmp' (*note Non-Local Exits::) and doesn't - return. - - void my_obstack_alloc_failed (void) - ... - obstack_alloc_failed_handler = &my_obstack_alloc_failed; - - - -File: libc.info, Node: Allocation in an Obstack, Next: Freeing Obstack Objects, Prev: Preparing for Obstacks, Up: Obstacks - -Allocation in an Obstack -........................ - - The most direct way to allocate an object in an obstack is with -`obstack_alloc', which is invoked almost like `malloc'. - - - Function: void * obstack_alloc (struct obstack *OBSTACK-PTR, int - SIZE) - This allocates an uninitialized block of SIZE bytes in an obstack - and returns its address. Here OBSTACK-PTR specifies which obstack - to allocate the block in; it is the address of the `struct obstack' - object which represents the obstack. Each obstack function or - macro requires you to specify an OBSTACK-PTR as the first argument. - - This function calls the obstack's `obstack_chunk_alloc' function if - it needs to allocate a new chunk of memory; it calls - `obstack_alloc_failed_handler' if allocation of memory by - `obstack_chunk_alloc' failed. - - For example, here is a function that allocates a copy of a string STR -in a specific obstack, which is in the variable `string_obstack': - - struct obstack string_obstack; - - char * - copystring (char *string) - { - size_t len = strlen (string) + 1; - char *s = (char *) obstack_alloc (&string_obstack, len); - memcpy (s, string, len); - return s; - } - - To allocate a block with specified contents, use the function -`obstack_copy', declared like this: - - - Function: void * obstack_copy (struct obstack *OBSTACK-PTR, void - *ADDRESS, int SIZE) - This allocates a block and initializes it by copying SIZE bytes of - data starting at ADDRESS. It calls `obstack_alloc_failed_handler' - if allocation of memory by `obstack_chunk_alloc' failed. - - - Function: void * obstack_copy0 (struct obstack *OBSTACK-PTR, void - *ADDRESS, int SIZE) - Like `obstack_copy', but appends an extra byte containing a null - character. This extra byte is not counted in the argument SIZE. - - The `obstack_copy0' function is convenient for copying a sequence of -characters into an obstack as a null-terminated string. Here is an -example of its use: - - char * - obstack_savestring (char *addr, int size) - { - return obstack_copy0 (&myobstack, addr, size); - } - -Contrast this with the previous example of `savestring' using `malloc' -(*note Basic Allocation::). - - -File: libc.info, Node: Freeing Obstack Objects, Next: Obstack Functions, Prev: Allocation in an Obstack, Up: Obstacks - -Freeing Objects in an Obstack -............................. - - To free an object allocated in an obstack, use the function -`obstack_free'. Since the obstack is a stack of objects, freeing one -object automatically frees all other objects allocated more recently in -the same obstack. - - - Function: void obstack_free (struct obstack *OBSTACK-PTR, void - *OBJECT) - If OBJECT is a null pointer, everything allocated in the obstack - is freed. Otherwise, OBJECT must be the address of an object - allocated in the obstack. Then OBJECT is freed, along with - everything allocated in OBSTACK since OBJECT. - - Note that if OBJECT is a null pointer, the result is an -uninitialized obstack. To free all memory in an obstack but leave it -valid for further allocation, call `obstack_free' with the address of -the first object allocated on the obstack: - - obstack_free (obstack_ptr, first_object_allocated_ptr); - - Recall that the objects in an obstack are grouped into chunks. When -all the objects in a chunk become free, the obstack library -automatically frees the chunk (*note Preparing for Obstacks::).

The obstack facility works -with all C compilers, including both ISO C and traditional C, but there -are precautions you must take if you plan to use compilers other than -GNU C. - - If you are using an old-fashioned non-ISO C compiler, all the obstack -"functions" are actually defined only as macros. You can call these -macros like functions, but you cannot use them in any other way (for -example, you cannot take their address). - - Calling the macros requires a special precaution: namely, the first -operand (the obstack pointer) may not contain any side effects, because -it may be computed more than once. For example, if you write this: - - obstack_alloc (get_obstack (), 4); - -you will find that `get_obstack' may be called several times. If you -use `*obstack_list_ptr++' as the obstack pointer argument, you will get -very strange results since the incrementation may occur several times. - - In ISO C, each function has both a macro definition and a function -definition. The function definition is used if you take the address of -the function without calling it. An ordinary call uses the macro -definition by default, but you can request the function definition -instead by writing the function name in parentheses, as shown here: - - char *x; - void *(*funcp) (); - /* Use the macro. */ - x = (char *) obstack_alloc (obptr, size); - /* Call the function. */ - x = (char *) (obstack_alloc) (obptr, size); - /* Take the address of the function. */ - funcp = obstack_alloc; - -This is the same situation that exists in ISO C for the standard library -functions. *Note Macro Definitions::. - - *Warning:* When you do use the macros, you must observe the -precaution of avoiding side effects in the first operand, even in ISO C. - - If you use the GNU C compiler, this precaution is not necessary, -because various language extensions in GNU C permit defining the macros -so as to compute each argument only once. - diff -u -udbrN glibc-2.3.2/manual/libc.info-40 glibc-2.3.2-200304020432/manual/libc.info-40 --- glibc-2.3.2/manual/libc.info-40 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-40 Thu Jan 1 01:00:00 1970 @@ -1,1192 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

That means that if two -signals of the same kind arrive close together, the second one will be -held until the first has been handled. (The handler can explicitly -unblock the signal using `sigprocmask', if you want to allow more -signals of this type to arrive; see *Note Process Signal Mask::.) - - However, your handler can still be interrupted by delivery of another -kind of signal.

These signals -are in addition to the signal for which the handler was invoked, and -any other signals that are normally blocked by the process. *Note -Blocking for Handler::. - - When the handler returns, the set of blocked signals is restored to -the value it had before the handler ran.

In effect, the signals merge into one. This situation can -arise when the signal is blocked, or in a multiprocessing environment -where the system is busy running some other processes while the signals -are delivered. This means, for example, that you cannot reliably use a -signal handler to count signals. The only distinction you can reliably -make is whether at least one signal has arrived since a given time in -the past. - - Here is an example of a handler for `SIGCHLD' that compensates for -the fact that the number of signals received may not equal the number of -child processes that generate them. It assumes that the program keeps -track of all the child processes with a chain of structures as follows: - - struct process - { - struct process *next; - /* The process ID of this child. */ - int pid; - /* The descriptor of the pipe or pseudo terminal - on which output comes from this child. */ - int input_descriptor; - /* Nonzero if this process has stopped or terminated. */ - sig_atomic_t have_status; - /* The status of this child; 0 if running, - otherwise a status value from `waitpid'. */ - int status; - }; - - struct process *process_list; - - This example also uses a flag to indicate whether signals have -arrived since some time in the past--whenever the program last cleared -it to zero. - - /* Nonzero means some child's status has changed - so look at `process_list' for the details. */ - int process_status_change; - - Here is the handler itself: - - void - sigchld_handler (int signo) - { - int old_errno = errno; - - while (1) { - register int pid; - int w; - struct process *p; - - /* Keep asking for a status until we get a definitive result. */ - do - { - errno = 0; - pid = waitpid (WAIT_ANY, &w, WNOHANG | WUNTRACED); - } - while (pid <= 0 && errno == EINTR); - - if (pid <= 0) { - /* A real failure means there are no more - stopped or terminated child processes, so return. */ - errno = old_errno; - return; - } - - /* Find the process that signaled us, and record its status. */ - - for (p = process_list; p; p = p->next) - if (p->pid == pid) { - p->status = w; - /* Indicate that the `status' field - has data to look at.

Examine `p->status' ... - } - } - -It is vital to clear the flag before examining the list; otherwise, if a -signal were delivered just before the clearing of the flag, and after -the appropriate element of the process list had been checked, the status -change would go unnoticed until the next signal arrived to set the flag -again. You could, of course, avoid this problem by blocking the signal -while scanning the list, but it is much more elegant to guarantee -correctness by doing things in the right order. - - The loop which checks process status avoids examining `p->status' -until it sees that status has been validly stored.

This technique uses a counter which is never -changed outside the handler. Instead of clearing the count, the program -remembers the previous value and sees whether it has changed since the -previous check.

The best practice is -to write a handler that does nothing but set an external variable that -the program checks regularly, and leave all serious work to the program. -This is best because the handler can be called asynchronously, at -unpredictable times--perhaps in the middle of a primitive function, or -even between the beginning and the end of a C operator that requires -multiple instructions. The data structures being manipulated might -therefore be in an inconsistent state when the handler function is -invoked. Even copying one `int' variable into another can take two -instructions on most machines. - - This means you have to be very careful about what you do in a signal -handler. - - * If your handler needs to access any global variables from your - program, declare those variables `volatile'. This tells the - compiler that the value of the variable might change - asynchronously, and inhibits certain optimizations that would be - invalidated by such modifications. - - * If you call a function in the handler, make sure it is "reentrant" - with respect to signals, or else make sure that the signal cannot - interrupt a call to a related function. - - A function can be non-reentrant if it uses memory that is not on the -stack. - - * If a function uses a static variable or a global variable, or a - dynamically-allocated object that it finds for itself, then it is - non-reentrant and any two calls to the function can interfere. - - For example, suppose that the signal handler uses `gethostbyname'. - This function returns its value in a static object, reusing the - same object each time. If the signal happens to arrive during a - call to `gethostbyname', or even after one (while the program is - still using the value), it will clobber the value that the program - asked for. - - However, if the program does not use `gethostbyname' or any other - function that returns information in the same object, or if it - always blocks signals around each use, then you are safe. - - There are a large number of library functions that return values - in a fixed object, always reusing the same object in this fashion, - and all of them cause the same problem. Function descriptions in - this manual always mention this behavior. - - * If a function uses and modifies an object that you supply, then it - is potentially non-reentrant; two calls can interfere if they use - the same object. - - This case arises when you do I/O using streams. Suppose that the - signal handler prints a message with `fprintf'. Suppose that the - program was in the middle of an `fprintf' call using the same - stream when the signal was delivered. Both the signal handler's - message and the program's data could be corrupted, because both - calls operate on the same data structure--the stream itself. - - However, if you know that the stream that the handler uses cannot - possibly be used by the program at a time when signals can arrive, - then you are safe. It is no problem if the program uses some - other stream. - - * On most systems, `malloc' and `free' are not reentrant, because - they use a static data structure which records what memory blocks - are free. As a result, no library functions that allocate or free - memory are reentrant. This includes functions that allocate space - to store a result. - - The best way to avoid the need to allocate memory in a handler is - to allocate in advance space for signal handlers to use. - - The best way to avoid freeing memory in a handler is to flag or - record the objects to be freed, and have the program check from - time to time whether anything is waiting to be freed. But this - must be done with care, because placing an object on a chain is - not atomic, and if it is interrupted by another signal handler - that does the same thing, you could "lose" one of the objects. - - * Any function that modifies `errno' is non-reentrant, but you can - correct for this: in the handler, save the original value of - `errno' and restore it before returning normally. This prevents - errors that occur within the signal handler from being confused - with errors from system calls at the point the program is - interrupted to run the handler. - - This technique is generally applicable; if you want to call in a - handler a function that modifies a particular object in memory, - you can make this safe by saving and restoring that object. - - * Merely reading from a memory object is safe provided that you can - deal with any of the values that might appear in the object at a - time when the signal can be delivered. Keep in mind that - assignment to some data types requires more than one instruction, - which means that the handler could run "in the middle of" an - assignment to the variable if its type is not atomic. *Note - Atomic Data Access::. - - * Merely writing into a memory object is safe as long as a sudden - change in the value, at any time when the handler might run, will - not disturb anything. - - -File: libc.info, Node: Atomic Data Access, Prev: Nonreentrancy, Up: Defining Handlers - -Atomic Data Access and Signal Handling --------------------------------------- - - Whether the data in your application concerns atoms, or mere text, -you have to be careful about the fact that access to a single datum is -not necessarily "atomic". This means that it can take more than one -instruction to read or write a single object. In such cases, a signal -handler might be invoked in the middle of reading or writing the object. - - There are three ways you can cope with this problem.

(Calling `printf' in the handler -is safe in this program because it is certainly not being called outside -the handler when the signal happens.) - - Clearly, this program can print a pair of zeros or a pair of ones. -But that's not all it can do! On most machines, it takes several -instructions to store a new value in `memory', and the value is stored -one word at a time. If the signal is delivered in between these -instructions, the handler might find that `memory.a' is zero and -`memory.b' is one (or vice versa). - - On some machines it may be possible to store a new value in `memory' -with just one instruction that cannot be interrupted. On these -machines, the handler will always print two zeros or two ones. - - -File: libc.info, Node: Atomic Types, Next: Atomic Usage, Prev: Non-atomic Example, Up: Atomic Data Access - -Atomic Types -............ - - To avoid uncertainty about interrupting access to a variable, you can -use a particular data type for which access is always atomic: -`sig_atomic_t'. Reading and writing this data type is guaranteed to -happen in a single instruction, so there's no way for a handler to run -"in the middle" of an access. - - The type `sig_atomic_t' is always an integer data type, but which -one it is, and how many bits it contains, may vary from machine to -machine. - - - Data Type: sig_atomic_t - This is an integer data type. Objects of this type are always - accessed atomically. - - In practice, you can assume that `int' and other integer types no -longer than `int' are atomic. You can also assume that pointer types -are atomic; that is very convenient. Both of these assumptions are -true on all of the machines that the GNU C library supports and on all -POSIX systems we know of. - - -File: libc.info, Node: Atomic Usage, Prev: Atomic Types, Up: Atomic Data Access - -Atomic Usage Patterns -..................... - - Certain patterns of access avoid any problem even if an access is -interrupted. For example, a flag which is set by the handler, and -tested and cleared by the main program from time to time, is always safe -even if access actually requires two instructions. To show that this is -so, we must consider each access that could be interrupted, and show -that there is no problem if it is interrupted. - - An interrupt in the middle of testing the flag is safe because -either it's recognized to be nonzero, in which case the precise value -doesn't matter, or it will be seen to be nonzero the next time it's -tested. - - An interrupt in the middle of clearing the flag is no problem because -either the value ends up zero, which is what happens if a signal comes -in just before the flag is cleared, or the value ends up nonzero, and -subsequent events occur as if the signal had come in just after the flag -was cleared. As long as the code handles both of these cases properly, -it can also handle a signal in the middle of clearing the flag. (This -is an example of the sort of reasoning you need to do to figure out -whether non-atomic usage is safe.) - - Sometimes you can insure uninterrupted access to one object by -protecting its use with another object, perhaps one whose type -guarantees atomicity. *Note Merged Signals::, for an example. - - -File: libc.info, Node: Interrupted Primitives, Next: Generating Signals, Prev: Defining Handlers, Up: Signal Handling - -Primitives Interrupted by Signals -================================= - - A signal can arrive and be handled while an I/O primitive such as -`open' or `read' is waiting for an I/O device. If the signal handler -returns, the system faces the question: what should happen next? - - POSIX specifies one approach: make the primitive fail right away. -The error code for this kind of failure is `EINTR'. This is flexible, -but usually inconvenient. Typically, POSIX applications that use signal -handlers must check for `EINTR' after each library function that can -return it, in order to try the call again. Often programmers forget to -check, which is a common source of error. - - The GNU library provides a convenient way to retry a call after a -temporary failure, with the macro `TEMP_FAILURE_RETRY': - - - Macro: TEMP_FAILURE_RETRY (EXPRESSION) - This macro evaluates EXPRESSION once. If it fails and reports - error code `EINTR', `TEMP_FAILURE_RETRY' evaluates it again, and - over and over until the result is not a temporary failure. - - The value returned by `TEMP_FAILURE_RETRY' is whatever value - EXPRESSION produced. - - BSD avoids `EINTR' entirely and provides a more convenient approach: -to restart the interrupted primitive, instead of making it fail. If -you choose this approach, you need not be concerned with `EINTR'. - - You can choose either approach with the GNU library. If you use -`sigaction' to establish a signal handler, you can specify how that -handler should behave. If you specify the `SA_RESTART' flag, return -from that handler will resume a primitive; otherwise, return from that -handler will cause `EINTR'. *Note Flags for Sigaction::. - - Another way to specify the choice is with the `siginterrupt' -function. *Note BSD Handler::. - - When you don't specify with `sigaction' or `siginterrupt' what a -particular handler should do, it uses a default choice. The default -choice in the GNU library depends on the feature test macros you have -defined. If you define `_BSD_SOURCE' or `_GNU_SOURCE' before calling -`signal', the default is to resume primitives; otherwise, the default -is to make them fail with `EINTR'. (The library contains alternate -versions of the `signal' function, and the feature test macros -determine which one you really call.) *Note Feature Test Macros::. - - The description of each primitive affected by this issue lists -`EINTR' among the error codes it can return. - - There is one situation where resumption never happens no matter which -choice you make: when a data-transfer function such as `read' or -`write' is interrupted by a signal after transferring part of the data. -In this case, the function returns the number of bytes already -transferred, indicating partial success. - - This might at first appear to cause unreliable behavior on -record-oriented devices (including datagram sockets; *note Datagrams::), -where splitting one `read' or `write' into two would read or write two -records. Actually, there is no problem, because interruption after a -partial transfer cannot happen on such devices; they always transfer an -entire record in one burst, with no waiting once data transfer has -started. - - -File: libc.info, Node: Generating Signals, Next: Blocking Signals, Prev: Interrupted Primitives, Up: Signal Handling - -Generating Signals -================== - - Besides signals that are generated as a result of a hardware trap or -interrupt, your program can explicitly send signals to itself or to -another process. - -* Menu: - -* Signaling Yourself:: A process can send a signal to itself. -* Signaling Another Process:: Send a signal to another process. -* Permission for kill:: Permission for using `kill'. -* Kill Example:: Using `kill' for Communication. - - -File: libc.info, Node: Signaling Yourself, Next: Signaling Another Process, Up: Generating Signals - -Signaling Yourself ------------------- - - A process can send itself a signal with the `raise' function. This -function is declared in `signal.h'. - - - Function: int raise (int SIGNUM) - The `raise' function sends the signal SIGNUM to the calling - process.

Some examples of situations where you -might want to send signals between processes are: - - * A parent process starts a child to perform a task--perhaps having - the child running an infinite loop--and then terminates the child - when the task is no longer needed. - - * A process executes as part of a group, and needs to terminate or - notify the other processes in the group when an error or other - event occurs. - - * Two processes need to synchronize while working together. - - This section assumes that you know a little bit about how processes -work. For more information on this subject, see *Note Processes::. - - The `kill' function is declared in `signal.h'. - - - Function: int kill (pid_t PID, int SIGNUM) - The `kill' function sends the signal SIGNUM to the process or - process group specified by PID. Besides the signals listed in - *Note Standard Signals::, SIGNUM can also have a value of zero to - check the validity of the PID. - - The PID specifies the process or process group to receive the - signal: - - `PID > 0' - The process whose identifier is PID. - - `PID == 0' - All processes in the same process group as the sender. - - `PID < -1' - The process group whose identifier is -PID. - - `PID == -1' - If the process is privileged, send the signal to all - processes except for some special system processes. - Otherwise, send the signal to all processes with the same - effective user ID. - - A process can send a signal to itself with a call like - `kill (getpid(), SIGNUM)'. If `kill' is used by a process to send - a signal to itself, and the signal is not blocked, then `kill' - delivers at least one signal (which might be some other pending - unblocked signal instead of the signal SIGNUM) to that process - before it returns. - - The return value from `kill' is zero if the signal can be sent - successfully. Otherwise, no signal is sent, and a value of `-1' is - returned. If PID specifies sending a signal to several processes, - `kill' succeeds if it can send the signal to at least one of them. - There's no way you can tell which of the processes got the signal - or whether all of them did. - - The following `errno' error conditions are defined for this - function: - - `EINVAL' - The SIGNUM argument is an invalid or unsupported number. - - `EPERM' - You do not have the privilege to send a signal to the process - or any of the processes in the process group named by PID. - - `ESCRH' - The PID argument does not refer to an existing process or - group. - - - Function: int killpg (int PGID, int SIGNUM) - This is similar to `kill', but sends signal SIGNUM to the process - group PGID. This function is provided for compatibility with BSD; - using `kill' to do this is more portable. - - As a simple example of `kill', the call `kill (getpid (), SIG)' has -the same effect as `raise (SIG)'. - - -File: libc.info, Node: Permission for kill, Next: Kill Example, Prev: Signaling Another Process, Up: Generating Signals - -Permission for using `kill' ---------------------------- - - There are restrictions that prevent you from using `kill' to send -signals to any random process. These are intended to prevent antisocial -behavior such as arbitrarily killing off processes belonging to another -user. In typical use, `kill' is used to pass signals between parent, -child, and sibling processes, and in these situations you normally do -have permission to send signals. The only common exception is when you -run a setuid program in a child process; if the program changes its -real UID as well as its effective UID, you may not have permission to -send a signal. The `su' program does this. - - Whether a process has permission to send a signal to another process -is determined by the user IDs of the two processes. This concept is -discussed in detail in *Note Process Persona::. - - Generally, for a process to be able to send a signal to another -process, either the sending process must belong to a privileged user -(like `root'), or the real or effective user ID of the sending process -must match the real or effective user ID of the receiving process. If -the receiving process has changed its effective user ID from the -set-user-ID mode bit on its process image file, then the owner of the -process image file is used in place of its current effective user ID. -In some implementations, a parent process might be able to send signals -to a child process even if the user ID's don't match, and other -implementations might enforce other restrictions. - - The `SIGCONT' signal is a special case. It can be sent if the -sender is part of the same session as the receiver, regardless of user -IDs. - - -File: libc.info, Node: Kill Example, Prev: Permission for kill, Up: Generating Signals - -Using `kill' for Communication ------------------------------- - - Here is a longer example showing how signals can be used for -interprocess communication. This is what the `SIGUSR1' and `SIGUSR2' -signals are provided for. Since these signals are fatal by default, -the process that is supposed to receive them must trap them through -`signal' or `sigaction'. - - In this example, a parent process forks a child process and then -waits for the child to complete its initialization. The child process -tells the parent when it is ready by sending it a `SIGUSR1' signal, -using the `kill' function. - - #include - #include - #include - #include - - /* When a `SIGUSR1' signal arrives, set this variable. */ - volatile sig_atomic_t usr_interrupt = 0; - - void - synch_signal (int sig) - { - usr_interrupt = 1; - } - - /* The child process executes this function. */ - void - child_function (void) - { - /* Perform initialization. */ - printf ("I'm here!!! My pid is %d.\n", (int) getpid ()); - - /* Let parent know you're done. */ - kill (getppid (), SIGUSR1); - - /* Continue with execution. */ - puts ("Bye, now...."); - exit (0); - } - - int - main (void) - { - struct sigaction usr_action; - sigset_t block_mask; - pid_t child_id; - - /* Establish the signal handler. */ - sigfillset (&block_mask); - usr_action.sa_handler = synch_signal; - usr_action.sa_mask = block_mask; - usr_action.sa_flags = 0; - sigaction (SIGUSR1, &usr_action, NULL); - - /* Create the child process. */ - child_id = fork (); - if (child_id == 0) - child_function (); /* Does not return. */ - - /* Busy wait for the child to send a signal. */ - while (!usr_interrupt) - ; - - /* Now continue execution. */ - puts ("That's all, folks!"); - - return 0; - } - - This example uses a busy wait, which is bad, because it wastes CPU -cycles that other programs could otherwise use. It is better to ask the -system to wait until the signal arrives. See the example in *Note -Waiting for a Signal::. - - -File: libc.info, Node: Blocking Signals, Next: Waiting for a Signal, Prev: Generating Signals, Up: Signal Handling - -Blocking Signals -================ - - Blocking a signal means telling the operating system to hold it and -deliver it later. Generally, a program does not block signals -indefinitely--it might as well ignore them by setting their actions to -`SIG_IGN'. But it is useful to block signals briefly, to prevent them -from interrupting sensitive operations. For instance: - - * You can use the `sigprocmask' function to block signals while you - modify global variables that are also modified by the handlers for - these signals. - - * You can set `sa_mask' in your `sigaction' call to block certain - signals while a particular signal handler runs. This way, the - signal handler can run without being interrupted itself by signals. - -* Menu: - -* Why Block:: The purpose of blocking signals. -* Signal Sets:: How to specify which signals to - block. -* Process Signal Mask:: Blocking delivery of signals to your - process during normal execution. -* Testing for Delivery:: Blocking to Test for Delivery of - a Signal. -* Blocking for Handler:: Blocking additional signals while a - handler is being run. -* Checking for Pending Signals:: Checking for Pending Signals -* Remembering a Signal:: How you can get almost the same - effect as blocking a signal, by - handling it and setting a flag - to be tested later. - - -File: libc.info, Node: Why Block, Next: Signal Sets, Up: Blocking Signals - -Why Blocking Signals is Useful ------------------------------- - - Temporary blocking of signals with `sigprocmask' gives you a way to -prevent interrupts during critical parts of your code. If signals -arrive in that part of the program, they are delivered later, after you -unblock them. - - One example where this is useful is for sharing data between a signal -handler and the rest of the program. If the type of the data is not -`sig_atomic_t' (*note Atomic Data Access::), then the signal handler -could run when the rest of the program has only half finished reading -or writing the data. This would lead to confusing consequences. - - To make the program reliable, you can prevent the signal handler from -running while the rest of the program is examining or modifying that -data--by blocking the appropriate signal around the parts of the -program that touch the data. - - Blocking signals is also necessary when you want to perform a certain -action only if a signal has not arrived. Suppose that the handler for -the signal sets a flag of type `sig_atomic_t'; you would like to test -the flag and perform the action if the flag is not set. This is -unreliable. Suppose the signal is delivered immediately after you test -the flag, but before the consequent action: then the program will -perform the action even though the signal has arrived. - - The only way to test reliably for whether a signal has yet arrived -is to test while the signal is blocked. - - -File: libc.info, Node: Signal Sets, Next: Process Signal Mask, Prev: Why Block, Up: Blocking Signals - -Signal Sets ------------ - - All of the signal blocking functions use a data structure called a -"signal set" to specify what signals are affected. Thus, every -activity involves two stages: creating the signal set, and then passing -it as an argument to a library function. - - These facilities are declared in the header file `signal.h'. - - - Data Type: sigset_t - The `sigset_t' data type is used to represent a signal set. - Internally, it may be implemented as either an integer or structure - type. - - For portability, use only the functions described in this section - to initialize, change, and retrieve information from `sigset_t' - objects--don't try to manipulate them directly. - - There are two ways to initialize a signal set. You can initially -specify it to be empty with `sigemptyset' and then add specified -signals individually. Or you can specify it to be full with -`sigfillset' and then delete specified signals individually. - - You must always initialize the signal set with one of these two -functions before using it in any other way. Don't try to set all the -signals explicitly because the `sigset_t' object might include some -other information (like a version field) that needs to be initialized as -well. (In addition, it's not wise to put into your program an -assumption that the system has no signals aside from the ones you know -about.) - - - Function: int sigemptyset (sigset_t *SET) - This function initializes the signal set SET to exclude all of the - defined signals. It always returns `0'. - - - Function: int sigfillset (sigset_t *SET) - This function initializes the signal set SET to include all of the - defined signals. Again, the return value is `0'. - - - Function: int sigaddset (sigset_t *SET, int SIGNUM) - This function adds the signal SIGNUM to the signal set SET. All - `sigaddset' does is modify SET; it does not block or unblock any - signals. - - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is defined for this function: - - `EINVAL' - The SIGNUM argument doesn't specify a valid signal. - - - Function: int sigdelset (sigset_t *SET, int SIGNUM) - This function removes the signal SIGNUM from the signal set SET. - All `sigdelset' does is modify SET; it does not block or unblock - any signals. The return value and error conditions are the same - as for `sigaddset'. - - Finally, there is a function to test what signals are in a signal -set: - - - Function: int sigismember (const sigset_t *SET, int SIGNUM) - The `sigismember' function tests whether the signal SIGNUM is a - member of the signal set SET. It returns `1' if the signal is in - the set, `0' if not, and `-1' if there is an error. - - The following `errno' error condition is defined for this function: - - `EINVAL' - The SIGNUM argument doesn't specify a valid signal. - - -File: libc.info, Node: Process Signal Mask, Next: Testing for Delivery, Prev: Signal Sets, Up: Blocking Signals - -Process Signal Mask -------------------- - - The collection of signals that are currently blocked is called the -"signal mask". Each process has its own signal mask. When you create -a new process (*note Creating a Process::), it inherits its parent's -mask. You can block or unblock signals with total flexibility by -modifying the signal mask. - - The prototype for the `sigprocmask' function is in `signal.h'. - - Note that you must not use `sigprocmask' in multi-threaded processes, -because each thread has its own signal mask and there is no single -process signal mask. According to POSIX, the behavior of `sigprocmask' -in a multi-threaded process is "unspeficied". Instead, use -`pthread_sigmask'. *Note Threads and Signal Handling::. - - - Function: int sigprocmask (int HOW, const sigset_t *restrict SET, - sigset_t *restrict OLDSET) - The `sigprocmask' function is used to examine or change the calling - process's signal mask. The HOW argument determines how the signal - mask is changed, and must be one of the following values: - - `SIG_BLOCK' - Block the signals in `set'--add them to the existing mask. In - other words, the new mask is the union of the existing mask - and SET. - - `SIG_UNBLOCK' - Unblock the signals in SET--remove them from the existing - mask. - - `SIG_SETMASK' - Use SET for the mask; ignore the previous value of the mask. - - The last argument, OLDSET, is used to return information about the - old process signal mask. If you just want to change the mask - without looking at it, pass a null pointer as the OLDSET argument. - Similarly, if you want to know what's in the mask without changing - it, pass a null pointer for SET (in this case the HOW argument is - not significant). The OLDSET argument is often used to remember - the previous signal mask in order to restore it later. (Since the - signal mask is inherited over `fork' and `exec' calls, you can't - predict what its contents are when your program starts running.) - - If invoking `sigprocmask' causes any pending signals to be - unblocked, at least one of those signals is delivered to the - process before `sigprocmask' returns. The order in which pending - signals are delivered is not specified, but you can control the - order explicitly by making multiple `sigprocmask' calls to unblock - various signals one at a time. - - The `sigprocmask' function returns `0' if successful, and `-1' to - indicate an error. The following `errno' error conditions are - defined for this function: - - `EINVAL' - The HOW argument is invalid. - - You can't block the `SIGKILL' and `SIGSTOP' signals, but if the - signal set includes these, `sigprocmask' just ignores them instead - of returning an error status. - - Remember, too, that blocking program error signals such as `SIGFPE' - leads to undesirable results for signals generated by an actual - program error (as opposed to signals sent with `raise' or `kill'). - This is because your program may be too broken to be able to - continue executing to a point where the signal is unblocked again. - *Note Program Error Signals::. - - -File: libc.info, Node: Testing for Delivery, Next: Blocking for Handler, Prev: Process Signal Mask, Up: Blocking Signals - -Blocking to Test for Delivery of a Signal ------------------------------------------ - - Now for a simple example. Suppose you establish a handler for -`SIGALRM' signals that sets a flag whenever a signal arrives, and your -main program checks this flag from time to time and then resets it. -You can prevent additional `SIGALRM' signals from arriving in the -meantime by wrapping the critical part of the code with calls to -`sigprocmask', like this: - - /* This variable is set by the SIGALRM signal handler. */ - volatile sig_atomic_t flag = 0; - - int - main (void) - { - sigset_t block_alarm; - - ... - - /* Initialize the signal mask. */ - sigemptyset (&block_alarm); - sigaddset (&block_alarm, SIGALRM); - - while (1) - { - /* Check if a signal has arrived; if so, reset the flag. */ - sigprocmask (SIG_BLOCK, &block_alarm, NULL); - if (flag) - { - ACTIONS-IF-NOT-ARRIVED - flag = 0; - } - sigprocmask (SIG_UNBLOCK, &block_alarm, NULL); - - ... - } - } - - -File: libc.info, Node: Blocking for Handler, Next: Checking for Pending Signals, Prev: Testing for Delivery, Up: Blocking Signals - -Blocking Signals for a Handler ------------------------------- - - When a signal handler is invoked, you usually want it to be able to -finish without being interrupted by another signal. From the moment the -handler starts until the moment it finishes, you must block signals that -might confuse it or corrupt its data. - - When a handler function is invoked on a signal, that signal is -automatically blocked (in addition to any other signals that are already -in the process's signal mask) during the time the handler is running. -If you set up a handler for `SIGTSTP', for instance, then the arrival -of that signal forces further `SIGTSTP' signals to wait during the -execution of the handler. - - However, by default, other kinds of signals are not blocked; they can -arrive during handler execution. - - The reliable way to block other kinds of signals during the -execution of the handler is to use the `sa_mask' member of the -`sigaction' structure. - - Here is an example: - - #include - #include - - void catch_stop (); - - void - install_handler (void) - { - struct sigaction setup_action; - sigset_t block_mask; - - sigemptyset (&block_mask); - /* Block other terminal-generated signals while handler runs. */ - sigaddset (&block_mask, SIGINT); - sigaddset (&block_mask, SIGQUIT); - setup_action.sa_handler = catch_stop; - setup_action.sa_mask = block_mask; - setup_action.sa_flags = 0; - sigaction (SIGTSTP, &setup_action, NULL); - } - - This is more reliable than blocking the other signals explicitly in -the code for the handler. If you block signals explicitly in the -handler, you can't avoid at least a short interval at the beginning of -the handler where they are not yet blocked. - - You cannot remove signals from the process's current mask using this -mechanism. However, you can make calls to `sigprocmask' within your -handler to block or unblock signals as you wish. - - In any case, when the handler returns, the system restores the mask -that was in place before the handler was entered. If any signals that -become unblocked by this restoration are pending, the process will -receive those signals immediately, before returning to the code that was -interrupted. - - -File: libc.info, Node: Checking for Pending Signals, Next: Remembering a Signal, Prev: Blocking for Handler, Up: Blocking Signals - -Checking for Pending Signals ----------------------------- - - You can find out which signals are pending at any time by calling -`sigpending'. This function is declared in `signal.h'. - - - Function: int sigpending (sigset_t *SET) - The `sigpending' function stores information about pending signals - in SET. If there is a pending signal that is blocked from - delivery, then that signal is a member of the returned set. (You - can test whether a particular signal is a member of this set using - `sigismember'; see *Note Signal Sets::.) - - The return value is `0' if successful, and `-1' on failure. - - Testing whether a signal is pending is not often useful. Testing -when that signal is not blocked is almost certainly bad design. - - Here is an example. - - #include - #include - - sigset_t base_mask, waiting_mask; - - sigemptyset (&base_mask); - sigaddset (&base_mask, SIGINT); - sigaddset (&base_mask, SIGTSTP); - - /* Block user interrupts while doing other processing. */ - sigprocmask (SIG_SETMASK, &base_mask, NULL); - ... - - /* After a while, check to see whether any signals are pending. */ - sigpending (&waiting_mask); - if (sigismember (&waiting_mask, SIGINT)) { - /* User has tried to kill the process. */ - } - else if (sigismember (&waiting_mask, SIGTSTP)) { - /* User has tried to stop the process. */ - } - - Remember that if there is a particular signal pending for your -process, additional signals of that same type that arrive in the -meantime might be discarded. For example, if a `SIGINT' signal is -pending when another `SIGINT' signal arrives, your program will -probably only see one of them when you unblock this signal. - - *Portability Note:* The `sigpending' function is new in POSIX.1. -Older systems have no equivalent facility. - diff -u -udbrN glibc-2.3.2/manual/libc.info-41 glibc-2.3.2-200304020432/manual/libc.info-41 --- glibc-2.3.2/manual/libc.info-41 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-41 Thu Jan 1 01:00:00 1970 @@ -1,1252 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

To avoid this calls to - `pause' should be protected using cancellation handlers. - - The `pause' function is declared in `unistd.h'. - - -File: libc.info, Node: Pause Problems, Next: Sigsuspend, Prev: Using Pause, Up: Waiting for a Signal - -Problems with `pause' ---------------------- - - The simplicity of `pause' can conceal serious timing errors that can -make a program hang mysteriously. - - It is safe to use `pause' if the real work of your program is done -by the signal handlers themselves, and the "main program" does nothing -but call `pause'. Each time a signal is delivered, the handler will do -the next batch of work that is to be done, and then return, so that the -main loop of the program can call `pause' again. - - You can't safely use `pause' to wait until one more signal arrives, -and then resume real work. Even if you arrange for the signal handler -to cooperate by setting a flag, you still can't use `pause' reliably. -Here is an example of this problem: - - /* `usr_interrupt' is set by the signal handler. */ - if (!usr_interrupt) - pause (); - - /* Do work once the signal arrives. */ - ... - -This has a bug: the signal could arrive after the variable -`usr_interrupt' is checked, but before the call to `pause'. If no -further signals arrive, the process would never wake up again. - - You can put an upper limit on the excess waiting by using `sleep' in -a loop, instead of using `pause'. (*Note Sleeping::, for more about -`sleep'.) Here is what this looks like: - - /* `usr_interrupt' is set by the signal handler. - while (!usr_interrupt) - sleep (1); - - /* Do work once the signal arrives. */ - ... - - For some purposes, that is good enough. But with a little more -complexity, you can wait reliably until a particular signal handler is -run, using `sigsuspend'. *Note Sigsuspend::. - - -File: libc.info, Node: Sigsuspend, Prev: Pause Problems, Up: Waiting for a Signal - -Using `sigsuspend' ------------------- - - The clean and reliable way to wait for a signal to arrive is to -block it and then use `sigsuspend'. By using `sigsuspend' in a loop, -you can wait for certain kinds of signals, while letting other kinds of -signals be handled by their handlers. - - - Function: int sigsuspend (const sigset_t *SET) - This function replaces the process's signal mask with SET and then - suspends the process until a signal is delivered whose action is - either to terminate the process or invoke a signal handling - function. In other words, the program is effectively suspended - until one of the signals that is not a member of SET arrives. - - If the process is woken up by delivery of a signal that invokes a - handler function, and the handler function returns, then - `sigsuspend' also returns. - - The mask remains SET only as long as `sigsuspend' is waiting. The - function `sigsuspend' always restores the previous signal mask - when it returns. - - The return value and error conditions are the same as for `pause'. - - With `sigsuspend', you can replace the `pause' or `sleep' loop in -the previous section with something completely reliable: - - sigset_t mask, oldmask; - - ... - - /* Set up the mask of signals to temporarily block. */ - sigemptyset (&mask); - sigaddset (&mask, SIGUSR1); - - ... - - /* Wait for a signal to arrive. */ - sigprocmask (SIG_BLOCK, &mask, &oldmask); - while (!usr_interrupt) - sigsuspend (&oldmask); - sigprocmask (SIG_UNBLOCK, &mask, NULL); - - This last piece of code is a little tricky. The key point to -remember here is that when `sigsuspend' returns, it resets the process's -signal mask to the original value, the value from before the call to -`sigsuspend'--in this case, the `SIGUSR1' signal is once again blocked. -The second call to `sigprocmask' is necessary to explicitly unblock -this signal. - - One other point: you may be wondering why the `while' loop is -necessary at all, since the program is apparently only waiting for one -`SIGUSR1' signal. The answer is that the mask passed to `sigsuspend' -permits the process to be woken up by the delivery of other kinds of -signals, as well--for example, job control signals. If the process is -woken up by a signal that doesn't set `usr_interrupt', it just suspends -itself again until the "right" kind of signal eventually arrives. - - This technique takes a few more lines of preparation, but that is -needed just once for each kind of wait criterion you want to use.

(Some non-GNU debuggers on some machines may get -confused if you examine a stack trace while a handler that uses the -signal stack is running.) - - There are two interfaces for telling the system to use a separate -signal stack. `sigstack' is the older interface, which comes from 4.2 -BSD. `sigaltstack' is the newer interface, and comes from 4.4 BSD. -The `sigaltstack' interface has the advantage that it does not require -your program to know which direction the stack grows, which depends on -the specific machine and operating system. - - - Data Type: stack_t - This structure describes a signal stack.

The - size of a signal stack *must* be greater than this. - - For most cases, just using `SIGSTKSZ' for `ss_size' is - sufficient. But if you know how much stack space your - program's signal handlers will need, you may want to use - a different size. In this case, you should allocate - `MINSIGSTKSZ' additional bytes for the signal stack and - increase `ss_size' accordingly. - - `int ss_flags' - This field contains the bitwise OR of these flags: - - `SS_DISABLE' - This tells the system that it should not use the signal - stack. - - `SS_ONSTACK' - This is set by the system, and indicates that the signal - stack is currently in use.

It is -up to you to write a function named `main'--otherwise, you won't even -be able to link your program without errors. - - In ISO C you can define `main' either to take no arguments, or to -take two arguments that represent the command line arguments to the -program, like this: - - int main (int ARGC, char *ARGV[]) - - The command line arguments are the whitespace-separated tokens given -in the shell command used to invoke the program; thus, in `cat foo -bar', the arguments are `foo' and `bar'. The only way a program can -look at its command line arguments is via the arguments of `main'. If -`main' doesn't take arguments, then you cannot get at the command line. - - The value of the ARGC argument is the number of command line -arguments. The ARGV argument is a vector of C strings; its elements -are the individual command line argument strings. The file name of the -program being run is also included in the vector as the first element; -the value of ARGC counts this element. A null pointer always follows -the last element: `ARGV[ARGC]' is this null pointer. - - For the command `cat foo bar', ARGC is 3 and ARGV has three -elements, `"cat"', `"foo"' and `"bar"'. - - In Unix systems you can define `main' a third way, using three -arguments: - - int main (int ARGC, char *ARGV[], char *ENVP[]) - - The first two arguments are just the same. The third argument ENVP -gives the program's environment; it is the same as the value of -`environ'. *Note Environment Variables::.

Thus, `-abc' is equivalent to - `-a -b -c'. - - * Option names are single alphanumeric characters (as for `isalnum'; - *note Classification of Characters::). - - * Certain options require an argument. For example, the `-o' command - of the `ld' command requires an argument--an output file name. - - * An option and its argument may or may not appear as separate - tokens. (In other words, the whitespace separating them is - optional.) Thus, `-o foo' and `-ofoo' are equivalent. - - * Options typically precede other non-option arguments. - - The implementations of `getopt' and `argp_parse' in the GNU C - library normally make it appear as if all the option arguments were - specified before all the non-option arguments for the purposes of - parsing, even if the user of your program intermixed option and - non-option arguments. They do this by reordering the elements of - the ARGV array. This behavior is nonstandard; if you want to - suppress it, define the `_POSIX_OPTION_ORDER' environment variable. - *Note Standard Environment::. - - * The argument `--' terminates all options; any following arguments - are treated as non-option arguments, even if they begin with a - hyphen. - - * A token consisting of a single hyphen character is interpreted as - an ordinary non-option argument. By convention, it is used to - specify input from or output to the standard input and output - streams. - - * Options may be supplied in any order, or appear multiple times. - The interpretation is left up to the particular application - program. - - GNU adds "long options" to these conventions. Long options consist -of `--' followed by a name made of alphanumeric characters and dashes. -Option names are typically one to three words long, with hyphens to -separate words. Users can abbreviate the option names as long as the -abbreviations are unique. - - To specify an argument for a long option, write `--NAME=VALUE'. -This syntax enables a long option to accept an argument that is itself -optional. - - Eventually, the GNU system will provide completion for long option -names in the shell. - - -File: libc.info, Node: Parsing Program Arguments, Prev: Argument Syntax, Up: Program Arguments - -Parsing Program Arguments -------------------------- - - If the syntax for the command line arguments to your program is -simple enough, you can simply pick the arguments off from ARGV by hand. -But unless your program takes a fixed number of arguments, or all of the -arguments are interpreted in the same way (as file names, for example), -you are usually better off using `getopt' (*note Getopt::) or -`argp_parse' (*note Argp::) to do the parsing. - - `getopt' is more standard (the short-option only version of it is a -part of the POSIX standard), but using `argp_parse' is often easier, -both for very simple and very complex option structures, because it -does more of the dirty work for you. - -* Menu: - -* Getopt:: Parsing program options using `getopt'. -* Argp:: Parsing program options using `argp_parse'. -* Suboptions:: Some programs need more detailed options. -* Suboptions Example:: This shows how it could be done for `mount'. - - -File: libc.info, Node: Getopt, Next: Argp, Up: Parsing Program Arguments - -Parsing program options using `getopt' -====================================== - - The `getopt' and `getopt_long' functions automate some of the chore -involved in parsing typical unix command line options. - -* Menu: - -* Using Getopt:: Using the `getopt' function. -* Example of Getopt:: An example of parsing options with `getopt'. -* Getopt Long Options:: GNU suggests utilities accept long-named - options; here is one way to do. -* Getopt Long Option Example:: An example of using `getopt_long'. - - -File: libc.info, Node: Using Getopt, Next: Example of Getopt, Up: Getopt - -Using the `getopt' function ---------------------------- - - Here are the details about how to call the `getopt' function.

You can use this for providing your own - diagnostic messages. - - - Variable: int optind - This variable is set by `getopt' to the index of the next element - of the ARGV array to be processed. Once `getopt' has found all of - the option arguments, you can use this variable to determine where - the remaining non-option arguments begin. The initial value of - this variable is `1'. - - - Variable: char * optarg - This variable is set by `getopt' to point at the value of the - option argument, for those options that accept arguments. - - - Function: int getopt (int ARGC, char **ARGV, const char *OPTIONS) - The `getopt' function gets the next option argument from the - argument list specified by the ARGV and ARGC arguments. Normally - these values come directly from the arguments received by `main'. - - The OPTIONS argument is a string that specifies the option - characters that are valid for this program. An option character - in this string can be followed by a colon (`:') to indicate that - it takes a required argument. If an option character is followed - by two colons (`::'), its argument is optional; this is a GNU - extension. - - `getopt' has three ways to deal with options that follow - non-options ARGV elements. The special argument `--' forces in - all cases the end of option scanning. - - * The default is to permute the contents of ARGV while scanning - it so that eventually all the non-options are at the end. - This allows options to be given in any order, even with - programs that were not written to expect this. - - * If the OPTIONS argument string begins with a hyphen (`-'), - this is treated specially. It permits arguments that are not - options to be returned as if they were associated with option - character `\1'. - - * POSIX demands the following behavior: The first non-option - stops option processing. This mode is selected by either - setting the environment variable `POSIXLY_CORRECT' or - beginning the OPTIONS argument string with a plus sign (`+'). - - The `getopt' function returns the option character for the next - command line option. When no more option arguments are available, - it returns `-1'. There may still be more non-option arguments; you - must compare the external variable `optind' against the ARGC - parameter to check this. - - If the option has an argument, `getopt' returns the argument by - storing it in the variable OPTARG. You don't ordinarily need to - copy the `optarg' string, since it is a pointer into the original - ARGV array, not into a static area that might be overwritten. - - If `getopt' finds an option character in ARGV that was not - included in OPTIONS, or a missing option argument, it returns `?' - and sets the external variable `optopt' to the actual option - character. If the first character of OPTIONS is a colon (`:'), - then `getopt' returns `:' instead of `?' to indicate a missing - option argument.

You should - arrange distinct values in the `val' field for options with - different meanings, so you can decode these values after - `getopt_long' returns. If the long option is equivalent to a short - option, you can use the short option's character code in `val'. - - If `flag' is not a null pointer, that means this option should just - set a flag in the program.

In this case, `getopt_long' returns `0'. - - For any long option, `getopt_long' tells you the index in the array - LONGOPTS of the options definition, by storing it into - `*INDEXPTR'. You can get the name of the option with - `LONGOPTS[*INDEXPTR].name'. So you can distinguish among long - options either by the values in their `val' fields or by their - indices. You can also distinguish in this way among long options - that set flags. - - When a long option has an argument, `getopt_long' puts the argument - value in the variable `optarg' before returning. When the option - has no argument, the value in `optarg' is a null pointer. This is - how you can tell whether an optional argument was supplied. - - When `getopt_long' has no more options to handle, it returns `-1', - and leaves in the variable `optind' the index in ARGV of the next - remaining argument. - - Since long option names were used before before the `getopt_long' -options was invented there are program interfaces which require programs -to recognize options like `-option value' instead of `--option value'. -To enable these programs to use the GNU getopt functionality there is -one more function available. - - - Function: int getopt_long_only (int ARGC, char *const *ARGV, const - char *SHORTOPTS, const struct option *LONGOPTS, int *INDEXPTR) - The `getopt_long_only' function is equivalent to the `getopt_long' - function but it allows to specify the user of the application to - pass long options with only `-' instead of `--'. The `--' prefix - is still recognized but instead of looking through the short - options if a `-' is seen it is first tried whether this parameter - names a long option. If not, it is parsed as a short option. - - Assuming `getopt_long_only' is used starting an application with - - app -foo - - the `getopt_long_only' will first look for a long option named - `foo'. If this is not found, the short options `f', `o', and - again `o' are recognized. - - -File: libc.info, Node: Getopt Long Option Example, Prev: Getopt Long Options, Up: Getopt - -Example of Parsing Long Options with `getopt_long' --------------------------------------------------- - - #include - #include - #include - - /* Flag set by `--verbose'. */ - static int verbose_flag; - - int - main (argc, argv) - int argc; - char **argv; - { - int c; - - while (1) - { - static struct option long_options[] = - { - /* These options set a flag. */ - {"verbose", no_argument, &verbose_flag, 1}, - {"brief", no_argument, &verbose_flag, 0}, - /* These options don't set a flag. - We distinguish them by their indices. */ - {"add", no_argument, 0, 'a'}, - {"append", no_argument, 0, 'b'}, - {"delete", required_argument, 0, 'd'}, - {"create", required_argument, 0, 'c'}, - {"file", required_argument, 0, 'f'}, - {0, 0, 0, 0} - }; - /* `getopt_long' stores the option index here. */ - int option_index = 0; - - c = getopt_long (argc, argv, "abc:d:f:", - long_options, &option_index); - - /* Detect the end of the options. */ - if (c == -1) - break; - - switch (c) - { - case 0: - /* If this option set a flag, do nothing else now. */ - if (long_options[option_index].flag != 0) - break; - printf ("option %s", long_options[option_index].name); - if (optarg) - printf (" with arg %s", optarg); - printf ("\n"); - break; - - case 'a': - puts ("option -a\n"); - break; - - case 'b': - puts ("option -b\n"); - break; - - case 'c': - printf ("option -c with value `%s'\n", optarg); - break; - - case 'd': - printf ("option -d with value `%s'\n", optarg); - break; - - case 'f': - printf ("option -f with value `%s'\n", optarg); - break; - - case '?': - /* `getopt_long' already printed an error message. */ - break; - - default: - abort (); - } - } - - /* Instead of reporting `--verbose' - and `--brief' as they are encountered, - we report the final status resulting from them. */ - if (verbose_flag) - puts ("verbose flag is set"); - - /* Print any remaining command line arguments (not options). */ - if (optind < argc) - { - printf ("non-option ARGV-elements: "); - while (optind < argc) - printf ("%s ", argv[optind++]); - putchar ('\n'); - } - - exit (0); - } - - -File: libc.info, Node: Argp, Next: Suboptions, Prev: Getopt, Up: Parsing Program Arguments - -Parsing Program Options with Argp -================================= - - "Argp" is an interface for parsing unix-style argument vectors. -*Note Program Arguments::. - - Argp provides features unavailable in the more commonly used -`getopt' interface.

A typical usage is - to pass a pointer to a structure which is used for specifying - parameters to the parser and passing back the results. - - Unless the `ARGP_NO_EXIT' or `ARGP_NO_HELP' flags are included in - FLAGS, calling `argp_parse' may result in the program exiting. - This behavior is true if an error is detected, or when an unknown - option is encountered. *Note Program Termination::. - - If ARG_INDEX is non-null, the index of the first unparsed option - in ARGV is returned as a value. - - The return value is zero for successful parsing, or an error code - (*note Error Codes::) if an error is detected.

Multiple entries may be used for a single option -provided it has multiple names. This should be terminated by an entry -with zero in all fields. Note that when using an initialized C array -for options, writing `{ 0 }' is enough to achieve this. - - - Data Type: struct argp_option - This structure specifies a single option that an argp parser - understands, as well as how to parse and document that option. It - has the following fields: - - `const char *name' - The long name for this option, corresponding to the long - option `--NAME'; this field may be zero if this option _only_ - has a short name. To specify multiple names for an option, - additional entries may follow this one, with the - `OPTION_ALIAS' flag set. *Note Argp Option Flags::. - - `int key' - The integer key provided by the current option to the option - parser. If KEY has a value that is a printable ASCII - character (i.e., `isascii (KEY)' is true), it _also_ - specifies a short option `-CHAR', where CHAR is the ASCII - character with the code KEY. - - `const char *arg' - If non-zero, this is the name of an argument associated with - this option, which must be provided (e.g., with the - `--NAME=VALUE' or `-CHAR VALUE' syntaxes), unless the - `OPTION_ARG_OPTIONAL' flag (*note Argp Option Flags::) is - set, in which case it _may_ be provided. - - `int flags' - Flags associated with this option, some of which are referred - to above. *Note Argp Option Flags::. - - `const char *doc' - A documentation string for this option, for printing in help - messages. - - If both the `name' and `key' fields are zero, this string - will be printed tabbed left from the normal option column, - making it useful as a group header.

These flags control various aspects of how that -option is parsed or displayed in help messages: - -`OPTION_ARG_OPTIONAL' - The argument associated with this option is optional. - -`OPTION_HIDDEN' - This option isn't displayed in any help messages. - -`OPTION_ALIAS' - This option is an alias for the closest previous non-alias option. - This means that it will be displayed in the same help entry, and - will inherit fields other than `name' and `key' from the option - being aliased. - -`OPTION_DOC' - This option isn't actually an option and should be ignored by the - actual option parser. It is an arbitrary section of documentation - that should be displayed in much the same manner as the options. - This is known as a "documentation option". - - If this flag is set, then the option `name' field is displayed - unmodified (e.g., no `--' prefix is added) at the left-margin where - a _short_ option would normally be displayed, and this - documentation string is left in it's usual place. For purposes of - sorting, any leading whitespace and punctuation is ignored, unless - the first non-whitespace character is `-'. This entry is displayed - after all options, after `OPTION_DOC' entries with a leading `-', - in the same group. - -`OPTION_NO_USAGE' - This option shouldn't be included in `long' usage messages, but - should still be included in other help messages. This is intended - for options that are completely documented in an argp's `args_doc' - field. *Note Argp Parsers::. Including this option in the - generic usage list would be redundant, and should be avoided. - - For instance, if `args_doc' is `"FOO BAR\n-x BLAH"', and the `-x' - option's purpose is to distinguish these two cases, `-x' should - probably be marked `OPTION_NO_USAGE'. - - -File: libc.info, Node: Argp Parser Functions, Next: Argp Children, Prev: Argp Option Vectors, Up: Argp Parsers - -Argp Parser Functions ---------------------- - - The function pointed to by the `parser' field in a `struct argp' -(*note Argp Parsers::) defines what actions take place in response to -each option or argument parsed. It is also used as a hook, allowing a -parser to perform tasks at certain other points during parsing. - - Argp parser functions have the following type signature: - - error_t PARSER (int KEY, char *ARG, struct argp_state *STATE) - -where the arguments are as follows: - -KEY - For each option that is parsed, PARSER is called with a value of - KEY from that option's `key' field in the option vector. *Note - Argp Option Vectors::. PARSER is also called at other times with - special reserved keys, such as `ARGP_KEY_ARG' for non-option - arguments. *Note Argp Special Keys::. - -ARG - If KEY is an option, ARG is its given value. This defaults to - zero if no value is specified. Only options that have a non-zero - `arg' field can ever have a value. These must _always_ have a - value unless the `OPTION_ARG_OPTIONAL' flag is specified. If the - input being parsed specifies a value for an option that doesn't - allow one, an error results before PARSER ever gets called. - - If KEY is `ARGP_KEY_ARG', ARG is a non-option argument. Other - special keys always have a zero ARG. - -STATE - STATE points to a `struct argp_state', containing useful - information about the current parsing state for use by PARSER. - *Note Argp Parsing State::. - - When PARSER is called, it should perform whatever action is -appropriate for KEY, and return `0' for success, `ARGP_ERR_UNKNOWN' if -the value of KEY is not handled by this parser function, or a unix -error code if a real error occurred. *Note Error Codes::. - - - Macro: int ARGP_ERR_UNKNOWN - Argp parser functions should return `ARGP_ERR_UNKNOWN' for any KEY - value they do not recognize, or for non-option arguments (`KEY == - ARGP_KEY_ARG') that they are not equipped to handle. - - A typical parser function uses a switch statement on KEY: - - error_t - parse_opt (int key, char *arg, struct argp_state *state) - { - switch (key) - { - case OPTION_KEY: - ACTION - break; - ... - default: - return ARGP_ERR_UNKNOWN; - } - return 0; - } - -* Menu: - -* Keys: Argp Special Keys.

In the following example ARG and STATE refer to parser -function arguments. *Note Argp Parser Functions::. - -`ARGP_KEY_ARG' - This is not an option at all, but rather a command line argument, - whose value is pointed to by ARG. - - When there are multiple parser functions in play due to argp - parsers being combined, it's impossible to know which one will - handle a specific argument. Each is called until one returns 0 or - an error other than `ARGP_ERR_UNKNOWN'; if an argument is not - handled, `argp_parse' immediately returns success, without parsing - any more arguments. - - Once a parser function returns success for this key, that fact is - recorded, and the `ARGP_KEY_NO_ARGS' case won't be used. - _However_, if while processing the argument a parser function - decrements the `next' field of its STATE argument, the option - won't be considered processed; this is to allow you to actually - modify the argument, perhaps into an option, and have it processed - again. - -`ARGP_KEY_ARGS' - If a parser function returns `ARGP_ERR_UNKNOWN' for - `ARGP_KEY_ARG', it is immediately called again with the key - `ARGP_KEY_ARGS', which has a similar meaning, but is slightly more - convenient for consuming all remaining arguments. ARG is 0, and - the tail of the argument vector may be found at `STATE->argv + - STATE->next'. If success is returned for this key, and - `STATE->next' is unchanged, all remaining arguments are considered - to have been consumed. Otherwise, the amount by which - `STATE->next' has been adjusted indicates how many were used. - Here's an example that uses both, for different args: - - ... - case ARGP_KEY_ARG: - if (STATE->arg_num == 0) - /* First argument */ - first_arg = ARG; - else - /* Let the next case parse it. */ - return ARGP_KEY_UNKNOWN; - break; - case ARGP_KEY_ARGS: - remaining_args = STATE->argv + STATE->next; - num_remaining_args = STATE->argc - STATE->next; - break; - -`ARGP_KEY_END' - This indicates that there are no more command line arguments. - Parser functions are called in a different order, children first. - This allows each parser to clean up its state for the parent. - -`ARGP_KEY_NO_ARGS' - Because it's common to do some special processing if there aren't - any non-option args, parser functions are called with this key if - they didn't successfully process any non-option arguments. This - is called just before `ARGP_KEY_END', where more general validity - checks on previously parsed arguments take place. - -`ARGP_KEY_INIT' - This is passed in before any parsing is done. Afterwards, the - values of each element of the `child_input' field of STATE, if - any, are copied to each child's state to be the initial value of - the `input' when _their_ parsers are called. - -`ARGP_KEY_SUCCESS' - Passed in when parsing has successfully been completed, even if - arguments remain. - -`ARGP_KEY_ERROR' - Passed in if an error has occurred and parsing is terminated. In - this case a call with a key of `ARGP_KEY_SUCCESS' is never made. - -`ARGP_KEY_FINI' - The final key ever seen by any parser, even after - `ARGP_KEY_SUCCESS' and `ARGP_KEY_ERROR'. Any resources allocated - by `ARGP_KEY_INIT' may be freed here. At times, certain resources - allocated are to be returned to the caller after a successful - parse. In that case, those particular resources can be freed in - the `ARGP_KEY_ERROR' case. - - In all cases, `ARGP_KEY_INIT' is the first key seen by parser -functions, and `ARGP_KEY_FINI' the last, unless an error was returned -by the parser for `ARGP_KEY_INIT'. Other keys can occur in one the -following orders. OPT refers to an arbitrary option key: - -OPT... `ARGP_KEY_NO_ARGS' `ARGP_KEY_END' `ARGP_KEY_SUCCESS' - The arguments being parsed did not contain any non-option - arguments. - -( OPT | `ARGP_KEY_ARG' )... `ARGP_KEY_END' `ARGP_KEY_SUCCESS' - All non-option arguments were successfully handled by a parser - function. There may be multiple parser functions if multiple argp - parsers were combined. - -( OPT | `ARGP_KEY_ARG' )... `ARGP_KEY_SUCCESS' - Some non-option argument went unrecognized. - - This occurs when every parser function returns `ARGP_KEY_UNKNOWN' - for an argument, in which case parsing stops at that argument if - ARG_INDEX is a null pointer. Otherwise an error occurs. - - In all cases, if a non-null value for ARG_INDEX gets passed to -`argp_parse', the index of the first unparsed command-line argument is -passed back in that value. - - If an error occurs and is either detected by argp or because a parser -function returned an error value, each parser is called with -`ARGP_KEY_ERROR'. No further calls are made, except the final call -with `ARGP_KEY_FINI'. - - -File: libc.info, Node: Argp Helper Functions, Prev: Argp Parsing State, Up: Argp Parser Functions - -Functions For Use in Argp Parsers -................................. - - Argp provides a number of functions available to the user of argp -(*note Argp Parser Functions::), mostly for producing error messages. -These take as their first argument the STATE argument to the parser -function. *Note Argp Parsing State::. - - - Function: void argp_usage (const struct argp_state *STATE) - Outputs the standard usage message for the argp parser referred to - by STATE to `STATE->err_stream' and terminate the program with - `exit (argp_err_exit_status)'. *Note Argp Global Variables::. - - - Function: void argp_error (const struct argp_state *STATE, const - char *FMT, ...) - Prints the printf format string FMT and following args, preceded - by the program name and `:', and followed by a `Try ... --help' - message, and terminates the program with an exit status of - `argp_err_exit_status'. *Note Argp Global Variables::. - - - Function: void argp_failure (const struct argp_state *STATE, int - STATUS, int ERRNUM, const char *FMT, ...) - Similar to the standard gnu error-reporting function `error', this - prints the program name and `:', the printf format string FMT, and - the appropriate following args.

This - may be modified. - - One way to consume all remaining arguments in the input is to - set `STATE->next = STATE->argc', perhaps after recording the - value of the `next' field to find the consumed arguments. The - current option can be re-parsed immediately by decrementing - this field, then modifying `STATE->argv[STATE->next]' to - reflect the option that should be reexamined. - - `unsigned flags' - The flags supplied to `argp_parse'. These may be modified, - although some flags may only take effect when `argp_parse' is - first invoked. *Note Argp Flags::. - - `unsigned arg_num' - While calling a parsing function with the KEY argument - `ARGP_KEY_ARG', this represents the number of the current arg, - starting at 0. It is incremented after each `ARGP_KEY_ARG' - call returns. At all other times, this is the number of - `ARGP_KEY_ARG' arguments that have been processed. - - `int quoted' - If non-zero, the index in `argv' of the first argument - following a special `--' argument. This prevents anything - that follows from being interpreted as an option. It is only - set after argument parsing has proceeded past this point. - - `void *input' - An arbitrary pointer passed in from the caller of - `argp_parse', in the INPUT argument. - - `void **child_inputs' - These are values that will be passed to child parsers. This - vector will be the same length as the number of children in - the current parser. Each child parser will be given the - value of `STATE->child_inputs[I]' as _its_ `STATE->input' - field, where I is the index of the child in the this parser's - `children' field. *Note Argp Children::. - - `void *hook' - For the parser function's use. Initialized to 0, but - otherwise ignored by argp. - - `char *name' - The name used when printing messages. This is initialized to - `argv[0]', or `program_invocation_name' if `argv[0]' is - unavailable. - - `FILE *err_stream' - `FILE *out_stream' - The stdio streams used when argp prints. Error messages are - printed to `err_stream', all other output, such as `--help' - output) to `out_stream'. These are initialized to `stderr' - and `stdout' respectively. *Note Standard Streams::. - - `void *pstate' - Private, for use by the argp implementation. - - -File: libc.info, Node: Argp Children, Next: Argp Help Filtering, Prev: Argp Parser Functions, Up: Argp Parsers - -Combining Multiple Argp Parsers -------------------------------- - - The `children' field in a `struct argp' enables other argp parsers -to be combined with the referencing one for the parsing of a single set -of arguments. This field should point to a vector of `struct -argp_child', which is terminated by an entry having a value of zero in -the `argp' field. - - Where conflicts between combined parsers arise, as when two specify -an option with the same name, the parser conflicts are resolved in -favor of the parent argp parser(s), or the earlier of the argp parsers -in the list of children. - - - Data Type: struct argp_child - An entry in the list of subsidiary argp parsers pointed to by the - `children' field in a `struct argp'. The fields are as follows: - - `const struct argp *argp' - The child argp parser, or zero to end of the list. - - `int flags' - Flags for this child. - - `const char *header' - If non-zero, this is an optional header to be printed within - help output before the child options. As a side-effect, a - non-zero value forces the child options to be grouped - together. To achieve this effect without actually printing a - header string, use a value of `""'. As with header strings - specified in an option entry, the conventional value of the - last character is `:'. *Note Argp Option Vectors::. - - `int group' - This is where the child options are grouped relative to the - other `consolidated' options in the parent argp parser. The - values are the same as the `group' field in `struct - argp_option'. *Note Argp Option Vectors::. All - child-groupings follow parent options at a particular group - level. If both this field and `header' are zero, then the - child's options aren't grouped together, they are merged with - parent options at the parent option group level. - - - -File: libc.info, Node: Argp Flags, Next: Argp Help, Prev: Argp Parsers, Up: Argp - -Flags for `argp_parse' ----------------------- - - The default behavior of `argp_parse' is designed to be convenient -for the most common case of parsing program command line argument. To -modify these defaults, the following flags may be or'd together in the -FLAGS argument to `argp_parse': - -`ARGP_PARSE_ARGV0' - Don't ignore the first element of the ARGV argument to - `argp_parse'. Unless `ARGP_NO_ERRS' is set, the first element of - the argument vector is skipped for option parsing purposes, as it - corresponds to the program name in a command line. - -`ARGP_NO_ERRS' - Don't print error messages for unknown options to `stderr'; unless - this flag is set, `ARGP_PARSE_ARGV0' is ignored, as `argv[0]' is - used as the program name in the error messages. This flag implies - `ARGP_NO_EXIT'. This is based on the assumption that silent - exiting upon errors is bad behavior. - -`ARGP_NO_ARGS' - Don't parse any non-option args. Normally these are parsed by - calling the parse functions with a key of `ARGP_KEY_ARG', the - actual argument being the value. This flag needn't normally be - set, as the default behavior is to stop parsing as soon as an - argument fails to be parsed. *Note Argp Parser Functions::. - -`ARGP_IN_ORDER' - Parse options and arguments in the same order they occur on the - command line. Normally they're rearranged so that all options - come first. - -`ARGP_NO_HELP' - Don't provide the standard long option `--help', which ordinarily - causes usage and option help information to be output to `stdout' - and `exit (0)'. - -`ARGP_NO_EXIT' - Don't exit on errors, although they may still result in error - messages. - -`ARGP_LONG_ONLY' - Use the gnu getopt `long-only' rules for parsing arguments. This - allows long-options to be recognized with only a single `-' (i.e. - `-help'). This results in a less useful interface, and its use is - discouraged as it conflicts with the way most GNU programs work as - well as the GNU coding standards. - -`ARGP_SILENT' - Turns off any message-printing/exiting options, specifically - `ARGP_NO_EXIT', `ARGP_NO_ERRS', and `ARGP_NO_HELP'. - - -File: libc.info, Node: Argp Help Filtering, Prev: Argp Children, Up: Argp Parsers - -Customizing Argp Help Output ----------------------------- - - The `help_filter' field in a `struct argp' is a pointer to a -function that filters the text of help messages before displaying them. -They have a function signature like: - - char *HELP-FILTER (int KEY, const char *TEXT, void *INPUT) - -Where KEY is either a key from an option, in which case TEXT is that -option's help text. *Note Argp Option Vectors::. Alternately, one of -the special keys with names beginning with `ARGP_KEY_HELP_' might be -used, describing which other help text TEXT will contain. *Note Argp -Help Filter Keys::. - - The function should return either TEXT if it remains as-is, or a -replacement string allocated using `malloc'. This will be either be -freed by argp or zero, which prints nothing. The value of TEXT is -supplied _after_ any translation has been done, so if any of the -replacement text needs translation, it will be done by the filter -function.

Typical error cases -can be handled using `argp_usage' and `argp_error'. *Note Argp Helper -Functions::.

They control whether the function returns after -printing its output, or terminates the program: - -`ARGP_HELP_EXIT_ERR' - This will terminate the program with `exit (argp_err_exit_status)'. - -`ARGP_HELP_EXIT_OK' - This will terminate the program with `exit (0)'. - - The following flags are combinations of the basic flags for printing -standard messages: - -`ARGP_HELP_STD_ERR' - Assuming that an error message for a parsing error has printed, - this prints a message on how to get help, and terminates the - program with an error. - -`ARGP_HELP_STD_USAGE' - This prints a standard usage message and terminates the program - with an error.

The first mechanism uses -the ARGV and ARGC arguments to its `main' function, and is discussed in -*Note Program Arguments::. The second mechanism uses "environment -variables" and is discussed in this section. - - The ARGV mechanism is typically used to pass command-line arguments -specific to the particular program being invoked. The environment, on -the other hand, keeps track of information that is shared by many -programs, changes infrequently, and that is less frequently used. - - The environment variables discussed in this section are the same -environment variables that you set using assignments and the `export' -command in the shell. Programs executed from the shell inherit all of -the environment variables from the shell. - - Standard environment variables are used for information about the -user's home directory, terminal type, current locale, and so on; you -can define additional variables for other purposes. The set of all -environment variables that have values is collectively known as the -"environment". - - Names of environment variables are case-sensitive and must not -contain the character `='. System-defined environment variables are -invariably uppercase. - - The values of environment variables can be anything that can be -represented as a string. A value must not contain an embedded null -character, since this is assumed to terminate the string. - -* Menu: - -* Environment Access:: How to get and set the values of - environment variables. -* Standard Environment:: These environment variables have - standard interpretations. - - -File: libc.info, Node: Environment Access, Next: Standard Environment, Up: Environment Variables - -Environment Access ------------------- - - The value of an environment variable can be accessed with the -`getenv' function. This is declared in the header file `stdlib.h'. -All of the following functions can be safely used in multi-threaded -programs. It is made sure that concurrent modifications to the -environment do not lead to errors. - - - Function: char * getenv (const char *NAME) - This function returns a string that is the value of the environment - variable NAME. You must not modify this string. In some non-Unix - systems not using the GNU library, it might be overwritten by - subsequent calls to `getenv' (but not by any other library - function). If the environment variable NAME is not defined, the - value is a null pointer. - - - Function: int putenv (char *STRING) - The `putenv' function adds or removes definitions from the - environment. If the STRING is of the form `NAME=VALUE', the - definition is added to the environment. Otherwise, the STRING is - interpreted as the name of an environment variable, and any - definition for this variable in the environment is removed. - - The difference to the `setenv' function is that the exact string - given as the parameter STRING is put into the environment. If the - user should change the string after the `putenv' call this will - reflect in automatically in the environment. This also requires - that STRING is no automatic variable which scope is left before the - variable is removed from the environment. The same applies of - course to dynamically allocated variables which are freed later. - - This function is part of the extended Unix interface. Since it - was also available in old SVID libraries you should define either - _XOPEN_SOURCE or _SVID_SOURCE before including any header. - - - Function: int setenv (const char *NAME, const char *VALUE, int - REPLACE) - The `setenv' function can be used to add a new definition to the - environment. The entry with the name NAME is replaced by the - value `NAME=VALUE'. Please note that this is also true if VALUE - is the empty string. To do this a new string is created and the - strings NAME and VALUE are copied. A null pointer for the VALUE - parameter is illegal. If the environment already contains an - entry with key NAME the REPLACE parameter controls the action. If - replace is zero, nothing happens. Otherwise the old entry is - replaced by the new one. - - Please note that you cannot remove an entry completely using this - function. - - This function was originally part of the BSD library but is now - part of the Unix standard. - - - Function: int unsetenv (const char *NAME) - Using this function one can remove an entry completely from the - environment. If the environment contains an entry with the key - NAME this whole entry is removed. A call to this function is - equivalent to a call to `putenv' when the VALUE part of the string - is empty. - - The function return `-1' if NAME is a null pointer, points to an - empty string, or points to a string containing a `=' character. - It returns `0' if the call succeeded. - - This function was originally part of the BSD library but is now - part of the Unix standard. The BSD version had no return value, - though. - - There is one more function to modify the whole environment. This -function is said to be used in the POSIX.9 (POSIX bindings for Fortran -77) and so one should expect it did made it into POSIX.1. But this -never happened. But we still provide this function as a GNU extension -to enable writing standard compliant Fortran environments. - - - Function: int clearenv (void) - The `clearenv' function removes all entries from the environment. - Using `putenv' and `setenv' new entries can be added again later. - - If the function is successful it returns `0'. Otherwise the return - value is nonzero. - - You can deal directly with the underlying representation of -environment objects to add more variables to the environment (for -example, to communicate with another program you are about to execute; -*note Executing a File::). - - - Variable: char ** environ - The environment is represented as an array of strings. Each - string is of the format `NAME=VALUE'. The order in which strings - appear in the environment is not significant, but the same NAME - must not appear more than once. The last element of the array is - a null pointer. - - This variable is declared in the header file `unistd.h'. - - If you just want to get the value of an environment variable, use - `getenv'. - - Unix systems, and the GNU system, pass the initial value of -`environ' as the third argument to `main'. *Note Program Arguments::. - - -File: libc.info, Node: Standard Environment, Prev: Environment Access, Up: Environment Variables - -Standard Environment Variables ------------------------------- - - These environment variables have standard meanings.

You shouldn't try -to use these environment variable names for some other purpose. - -`HOME' - This is a string representing the user's "home directory", or - initial default working directory. - - The user can set `HOME' to any value. If you need to make sure to - obtain the proper home directory for a particular user, you should - not use `HOME'; instead, look up the user's name in the user - database (*note User Database::). - - For most purposes, it is better to use `HOME', precisely because - this lets the user specify the value. - -`LOGNAME' - This is the name that the user used to log in. Since the value in - the environment can be tweaked arbitrarily, this is not a reliable - way to identify the user who is running a program; a function like - `getlogin' (*note Who Logged In::) is better for that purpose. - - For most purposes, it is better to use `LOGNAME', precisely because - this lets the user specify the value. - -`PATH' - A "path" is a sequence of directory names which is used for - searching for a file. The variable `PATH' holds a path used for - searching for programs to be run. - - The `execlp' and `execvp' functions (*note Executing a File::) use - this environment variable, as do many shells and other utilities - which are implemented in terms of those functions. - - The syntax of a path is a sequence of directory names separated by - colons. An empty string instead of a directory name stands for the - current directory (*note Working Directory::). - - A typical value for this environment variable might be a string - like: - - :/bin:/etc:/usr/bin:/usr/new/X11:/usr/new:/usr/local/bin - - This means that if the user tries to execute a program named `foo', - the system will look for files named `foo', `/bin/foo', - `/etc/foo', and so on. The first of these files that exists is - the one that is executed. - -`TERM' - This specifies the kind of terminal that is receiving program - output. Some programs can make use of this information to take - advantage of special escape sequences or terminal modes supported - by particular kinds of terminals. Many programs which use the - termcap library (*note Find: (termcap)Finding a Terminal - Description.) use the `TERM' environment variable, for example. - -`TZ' - This specifies the time zone. *Note TZ Variable::, for - information about the format of this string and how it is used. - -`LANG' - This specifies the default locale to use for attribute categories - where neither `LC_ALL' nor the specific environment variable for - that category is set. *Note Locales::, for more information about - locales. - -`LC_ALL' - If this environment variable is set it overrides the selection for - all the locales done using the other `LC_*' environment variables. - The value of the other `LC_*' environment variables is simply - ignored in this case. - -`LC_COLLATE' - This specifies what locale to use for string sorting. - -`LC_CTYPE' - This specifies what locale to use for character sets and character - classification. - -`LC_MESSAGES' - This specifies what locale to use for printing messages and to - parse responses. - -`LC_MONETARY' - This specifies what locale to use for formatting monetary values. - -`LC_NUMERIC' - This specifies what locale to use for formatting numbers. - -`LC_TIME' - This specifies what locale to use for formatting date/time values. - -`NLSPATH' - This specifies the directories in which the `catopen' function - looks for message translation catalogs. - -`_POSIX_OPTION_ORDER' - If this environment variable is defined, it suppresses the usual - reordering of command line arguments by `getopt' and `argp_parse'. - *Note Argument Syntax::. - - -File: libc.info, Node: System Calls, Next: Program Termination, Prev: Environment Variables, Up: Program Basics - -System Calls -============ - - A system call is a request for service that a program makes of the -kernel. The service is generally something that only the kernel has -the privilege to do, such as doing I/O. Programmers don't normally -need to be concerned with system calls because there are functions in -the GNU C library to do virtually everything that system calls do. -These functions work by making system calls themselves. For example, -there is a system call that changes the permissions of a file, but you -don't need to know about it because you can just use the GNU C -library's `chmod' function. - - System calls are sometimes called kernel calls. - - However, there are times when you want to make a system call -explicitly, and for that, the GNU C library provides the `syscall' -function. `syscall' is harder to use and less portable than functions -like `chmod', but easier and more portable than coding the system call -in assembler instructions. - - `syscall' is most useful when you are working with a system call -which is special to your system or is newer than the GNU C library you -are using. `syscall' is implemented in an entirely generic way; the -function does not know anything about what a particular system call -does or even if it is valid. - - The description of `syscall' in this section assumes a certain -protocol for system calls on the various platforms on which the GNU C -library runs. That protocol is not defined by any strong authority, but -we won't describe it here either because anyone who is coding `syscall' -probably won't accept anything less than kernel and C library source -code as a specification of the interface between them anyway. - - `syscall' is declared in `unistd.h'. - - - Function: long int syscall (long int SYSNO, ...) - `syscall' performs a generic system call. - - SYSNO is the system call number. Each kind of system call is - identified by a number. Macros for all the possible system call - numbers are defined in `sys/syscall.h' - - The remaining arguments are the arguments for the system call, in - order, and their meanings depend on the kind of system call. Each - kind of system call has a definite number of arguments, from zero - to five. If you code more arguments than the system call takes, - the extra ones to the right are ignored. - - The return value is the return value from the system call, unless - the system call failed. In that case, `syscall' returns `-1' and - sets `errno' to an error code that the system call returned. Note - that system calls do not return `-1' when they succeed. - - If you specify an invalid SYSNO, `syscall' returns `-1' with - `errno' = `ENOSYS'. - - Example: - - - #include - #include - #include - - ... - - int rc; - - rc = syscall(SYS_chmod, "/etc/passwd", 0444); - - if (rc == -1) - fprintf(stderr, "chmod failed, errno = %d\n", errno); - - This, if all the compatibility stars are aligned, is equivalent to - the following preferable code: - - - #include - #include - #include - - ... - - int rc; - - rc = chmod("/etc/passwd", 0444); - if (rc == -1) - fprintf(stderr, "chmod failed, errno = %d\n", errno); - - - -File: libc.info, Node: Program Termination, Prev: System Calls, Up: Program Basics - -Program Termination -=================== - - The usual way for a program to terminate is simply for its `main' -function to return. The "exit status value" returned from the `main' -function is used to report information back to the process's parent -process or shell. - - A program can also terminate normally by calling the `exit' function. - - In addition, programs can be terminated by signals; this is -discussed in more detail in *Note Signal Handling::.

Returning from `main' is equivalent to calling `exit', -and the value that `main' returns is used as the argument to `exit'. - - - Function: void exit (int STATUS) - The `exit' function tells the system that the program is done, - which causes it to terminate the process. - - STATUS is the program's exit status, which becomes part of the - process' termination status. This function does not return. - - Normal termination causes the following actions: - - 1. Functions that were registered with the `atexit' or `on_exit' - functions are called in the reverse order of their registration. - This mechanism allows your application to specify its own - "cleanup" actions to be performed at program termination. - Typically, this is used to do things like saving program state - information in a file, or unlocking locks in shared data bases. - - 2. All open streams are closed, writing out any buffered output data. - See *Note Closing Streams::. In addition, temporary files opened - with the `tmpfile' function are removed; see *Note Temporary - Files::. - - 3. `_exit' is called, terminating the program. *Note Termination - Internals::. - - -File: libc.info, Node: Exit Status, Next: Cleanups on Exit, Prev: Normal Termination, Up: Program Termination - -Exit Status ------------ - - When a program exits, it can return to the parent process a small -amount of information about the cause of termination, using the "exit -status". This is a value between 0 and 255 that the exiting process -passes as an argument to `exit'. - - Normally you should use the exit status to report very broad -information about success or failure. You can't provide a lot of -detail about the reasons for the failure, and most parent processes -would not want much detail anyway. - - There are conventions for what sorts of status values certain -programs should return. The most common convention is simply 0 for -success and 1 for failure. Programs that perform comparison use a -different convention: they use status 1 to indicate a mismatch, and -status 2 to indicate an inability to compare. Your program should -follow an existing convention if an existing convention makes sense for -it. - - A general convention reserves status values 128 and up for special -purposes. In particular, the value 128 is used to indicate failure to -execute another program in a subprocess. This convention is not -universally obeyed, but it is a good idea to follow it in your programs. - - *Warning:* Don't try to use the number of errors as the exit status. -This is actually not very useful; a parent process would generally not -care how many errors occurred. Worse than that, it does not work, -because the status value is truncated to eight bits. Thus, if the -program tried to report 256 errors, the parent would receive a report -of 0 errors--that is, success. - - For the same reason, it does not work to use the value of `errno' as -the exit status--these can exceed 255. - - *Portability note:* Some non-POSIX systems use different conventions -for exit status values. For greater portability, you can use the -macros `EXIT_SUCCESS' and `EXIT_FAILURE' for the conventional status -value for success and failure, respectively. They are declared in the -file `stdlib.h'. - - - Macro: int EXIT_SUCCESS - This macro can be used with the `exit' function to indicate - successful program completion. - - On POSIX systems, the value of this macro is `0'. On other - systems, the value might be some other (possibly non-constant) - integer expression. - - - Macro: int EXIT_FAILURE - This macro can be used with the `exit' function to indicate - unsuccessful program completion in a general sense. - - On POSIX systems, the value of this macro is `1'. On other - systems, the value might be some other (possibly non-constant) - integer expression. Other nonzero status values also indicate - failures. Certain programs use different nonzero status values to - indicate particular kinds of "non-success". For example, `diff' - uses status value `1' to mean that the files are different, and - `2' or more to mean that there was difficulty in opening the files. - - Don't confuse a program's exit status with a process' termination -status. There are lots of ways a process can terminate besides having -it's program finish. In the event that the process termination _is_ -caused by program termination (i.e. `exit'), though, the program's exit -status becomes part of the process' termination status. - - -File: libc.info, Node: Cleanups on Exit, Next: Aborting a Program, Prev: Exit Status, Up: Program Termination - -Cleanups on Exit ----------------- - - Your program can arrange to run its own cleanup functions if normal -termination happens. If you are writing a library for use in various -application programs, then it is unreliable to insist that all -applications call the library's cleanup functions explicitly before -exiting.

Each process has its own address space and (usually) one -thread of control. A process executes a program; you can have multiple -processes executing the same program, but each process has its own copy -of the program within its own address space and executes it -independently of the other copies. - - Processes are organized hierarchically. Each process has a "parent -process" which explicitly arranged to create it. The processes created -by a given parent are called its "child processes". A child inherits -many of its attributes from the parent process. - - This chapter describes how a program can create, terminate, and -control child processes. Actually, there are three distinct operations -involved: creating a new child process, causing the new process to -execute a program, and coordinating the completion of the child process -with the original program. - - The `system' function provides a simple, portable mechanism for -running another program; it does all three steps automatically. If you -need more control over the details of how this is done, you can use the -primitive functions to do each step individually instead. - -* Menu: - -* Running a Command:: The easy way to run another program. -* Process Creation Concepts:: An overview of the hard way to do it. -* Process Identification:: How to get the process ID of a process. -* Creating a Process:: How to fork a child process. -* Executing a File:: How to make a process execute another program. -* Process Completion:: How to tell when a child process has completed. -* Process Completion Status:: How to interpret the status value - returned from a child process. -* BSD Wait Functions:: More functions, for backward compatibility. -* Process Creation Example:: A complete example program. - - -File: libc.info, Node: Running a Command, Next: Process Creation Concepts, Up: Processes - -Running a Command -================= - - The easy way to run another program is to use the `system' function. -This function does all the work of running a subprogram, but it -doesn't give you much control over the details: you have to wait until -the subprogram terminates before you can do anything else. - - - Function: int system (const char *COMMAND) - This function executes COMMAND as a shell command. In the GNU C - library, it always uses the default shell `sh' to run the command. - In particular, it searches the directories in `PATH' to find - programs to execute. The return value is `-1' if it wasn't - possible to create the shell process, and otherwise is the status - of the shell process. *Note Process Completion::, for details on - how this status code can be interpreted. - - If the COMMAND argument is a null pointer, a return value of zero - indicates that no command processor is available. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `system' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this calls to - `system' should be protected using cancellation handlers. - - The `system' function is declared in the header file `stdlib.h'. - - *Portability Note:* Some C implementations may not have any notion -of a command processor that can execute other programs. You can -determine whether a command processor exists by executing -`system (NULL)'; if the return value is nonzero, a command processor is -available. - - The `popen' and `pclose' functions (*note Pipe to a Subprocess::) -are closely related to the `system' function. They allow the parent -process to communicate with the standard input and output channels of -the command being executed. - - -File: libc.info, Node: Process Creation Concepts, Next: Process Identification, Prev: Running a Command, Up: Processes - -Process Creation Concepts -========================= - - This section gives an overview of processes and of the steps -involved in creating a process and making it run another program. - - Each process is named by a "process ID" number. A unique process ID -is allocated to each process when it is created. The "lifetime" of a -process ends when its termination is reported to its parent process; at -that time, all of the process resources, including its process ID, are -freed. - - Processes are created with the `fork' system call (so the operation -of creating a new process is sometimes called "forking" a process). -The "child process" created by `fork' is a copy of the original "parent -process", except that it has its own process ID. - - After forking a child process, both the parent and child processes -continue to execute normally. If you want your program to wait for a -child process to finish executing before continuing, you must do this -explicitly after the fork operation, by calling `wait' or `waitpid' -(*note Process Completion::). These functions give you limited -information about why the child terminated--for example, its exit -status code. - - A newly forked child process continues to execute the same program as -its parent process, at the point where the `fork' call returns. You -can use the return value from `fork' to tell whether the program is -running in the parent process or the child. - - Having several processes run the same program is only occasionally -useful. But the child can execute another program using one of the -`exec' functions; see *Note Executing a File::. The program that the -process is executing is called its "process image". Starting execution -of a new program causes the process to forget all about its previous -process image; when the new program exits, the process exits too, -instead of returning to the previous process image. - - -File: libc.info, Node: Process Identification, Next: Creating a Process, Prev: Process Creation Concepts, Up: Processes - -Process Identification -====================== - - The `pid_t' data type represents process IDs. You can get the -process ID of a process by calling `getpid'. The function `getppid' -returns the process ID of the parent of the current process (this is -also known as the "parent process ID"). Your program should include -the header files `unistd.h' and `sys/types.h' to use these functions. - - - Data Type: pid_t - The `pid_t' data type is a signed integer type which is capable of - representing a process ID. In the GNU library, this is an `int'. - - - Function: pid_t getpid (void) - The `getpid' function returns the process ID of the current - process. - - - Function: pid_t getppid (void) - The `getppid' function returns the process ID of the parent of the - current process. - - -File: libc.info, Node: Creating a Process, Next: Executing a File, Prev: Process Identification, Up: Processes - -Creating a Process -================== - - The `fork' function is the primitive for creating a process. It is -declared in the header file `unistd.h'. - - - Function: pid_t fork (void) - The `fork' function creates a new process. - - If the operation is successful, there are then both parent and - child processes and both see `fork' return, but with different - values: it returns a value of `0' in the child process and returns - the child's process ID in the parent process. - - If process creation failed, `fork' returns a value of `-1' in the - parent process. The following `errno' error conditions are - defined for `fork': - - `EAGAIN' - There aren't enough system resources to create another - process, or the user already has too many processes running. - This means exceeding the `RLIMIT_NPROC' resource limit, which - can usually be increased; *note Limits on Resources::. - - `ENOMEM' - The process requires more space than the system can supply. - - The specific attributes of the child process that differ from the -parent process are: - - * The child process has its own unique process ID. - - * The parent process ID of the child process is the process ID of its - parent process. - - * The child process gets its own copies of the parent process's open - file descriptors. Subsequently changing attributes of the file - descriptors in the parent process won't affect the file - descriptors in the child, and vice versa. *Note Control - Operations::. However, the file position associated with each - descriptor is shared by both processes; *note File Position::. - - * The elapsed processor times for the child process are set to zero; - see *Note Processor Time::. - - * The child doesn't inherit file locks set by the parent process. - *Note Control Operations::. - - * The child doesn't inherit alarms set by the parent process. *Note - Setting an Alarm::. - - * The set of pending signals (*note Delivery of Signal::) for the - child process is cleared. (The child process inherits its mask of - blocked signals and signal actions from the parent process.) - - - Function: pid_t vfork (void) - The `vfork' function is similar to `fork' but on some systems it - is more efficient; however, there are restrictions you must follow - to use it safely. - - While `fork' makes a complete copy of the calling process's address - space and allows both the parent and child to execute - independently, `vfork' does not make this copy. Instead, the - child process created with `vfork' shares its parent's address - space until it calls `_exit' or one of the `exec' functions. In - the meantime, the parent process suspends execution. - - You must be very careful not to allow the child process created - with `vfork' to modify any global data or even local variables - shared with the parent. Furthermore, the child process cannot - return from (or do a long jump out of) the function that called - `vfork'! This would leave the parent process's control - information very confused. If in doubt, use `fork' instead. - - Some operating systems don't really implement `vfork'. The GNU C - library permits you to use `vfork' on all systems, but actually - executes `fork' if `vfork' isn't available. If you follow the - proper precautions for using `vfork', your program will still work - even if the system uses `fork' instead. - diff -u -udbrN glibc-2.3.2/manual/libc.info-44 glibc-2.3.2-200304020432/manual/libc.info-44 --- glibc-2.3.2/manual/libc.info-44 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-44 Thu Jan 1 01:00:00 1970 @@ -1,1175 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

They are declared in the -header file `unistd.h'. - - - Function: int execv (const char *FILENAME, char *const ARGV[]) - The `execv' function executes the file named by FILENAME as a new - process image. - - The ARGV argument is an array of null-terminated strings that is - used to provide a value for the `argv' argument to the `main' - function of the program to be executed. The last element of this - array must be a null pointer. By convention, the first element of - this array is the file name of the program sans directory names. - *Note Program Arguments::, for full details on how programs can - access these arguments. - - The environment for the new process image is taken from the - `environ' variable of the current process image; see *Note - Environment Variables::, for information about environments. - - - Function: int execl (const char *FILENAME, const char *ARG0, ...) - This is similar to `execv', but the ARGV strings are specified - individually instead of as an array. A null pointer must be - passed as the last such argument. - - - Function: int execve (const char *FILENAME, char *const ARGV[], char - *const ENV[]) - This is similar to `execv', but permits you to specify the - environment for the new program explicitly as the ENV argument. - This should be an array of strings in the same format as for the - `environ' variable; see *Note Environment Access::. - - - Function: int execle (const char *FILENAME, const char *ARG0, char - *const ENV[], ...) - This is similar to `execl', but permits you to specify the - environment for the new program explicitly. The environment - argument is passed following the null pointer that marks the last - ARGV argument, and should be an array of strings in the same - format as for the `environ' variable. - - - Function: int execvp (const char *FILENAME, char *const ARGV[]) - The `execvp' function is similar to `execv', except that it - searches the directories listed in the `PATH' environment variable - (*note Standard Environment::) to find the full file name of a - file from FILENAME if FILENAME does not contain a slash. - - This function is useful for executing system utility programs, - because it looks for them in the places that the user has chosen. - Shells use it to run the commands that users type. - - - Function: int execlp (const char *FILENAME, const char *ARG0, ...) - This function is like `execl', except that it performs the same - file name searching as the `execvp' function. - - The size of the argument list and environment list taken together -must not be greater than `ARG_MAX' bytes. *Note General Limits::. In -the GNU system, the size (which compares against `ARG_MAX') includes, -for each string, the number of characters in the string, plus the size -of a `char *', plus one, rounded up to a multiple of the size of a -`char *'. Other systems may have somewhat different rules for counting. - - These functions normally don't return, since execution of a new -program causes the currently executing program to go away completely. -A value of `-1' is returned in the event of a failure. In addition to -the usual file name errors (*note File Name Errors::), the following -`errno' error conditions are defined for these functions: - -`E2BIG' - The combined size of the new program's argument list and - environment list is larger than `ARG_MAX' bytes.

Normally, the calling - process is suspended until the child process makes status - information available by terminating. - - Other values for the PID argument have special interpretations. A - value of `-1' or `WAIT_ANY' requests status information for any - child process; a value of `0' or `WAIT_MYPGRP' requests - information for any child process in the same process group as the - calling process; and any other negative value - PGID requests - information for any child process whose process group ID is PGID. - - If status information for a child process is available - immediately, this function returns immediately without waiting. - If more than one eligible child process has status information - available, one of them is chosen randomly, and its status is - returned immediately. To get the status from the other eligible - child processes, you need to call `waitpid' again. - - The OPTIONS argument is a bit mask. Its value should be the - bitwise OR (that is, the `|' operator) of zero or more of the - `WNOHANG' and `WUNTRACED' flags. You can use the `WNOHANG' flag - to indicate that the parent process shouldn't wait; and the - `WUNTRACED' flag to request status information from stopped - processes as well as processes that have terminated. - - The status information from the child process is stored in the - object that STATUS-PTR points to, unless STATUS-PTR is a null - pointer. - - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `waitpid' is called.

If there are child processes but none - of them is waiting to be noticed, `waitpid' will block until one - is. However, if the `WNOHANG' option was specified, `waitpid' - will return zero instead of blocking. - - If a specific PID to wait for was given to `waitpid', it will - ignore all other children (if any). Therefore if there are - children waiting to be noticed but the child whose PID was - specified is not one of them, `waitpid' will block or return zero - as described above. - - A value of `-1' is returned in case of error.

It - has the following members: - - `int w_termsig' - The value of this member is the same as that of the - `WTERMSIG' macro. - - `int w_coredump' - The value of this member is the same as that of the - `WCOREDUMP' macro. - - `int w_retcode' - The value of this member is the same as that of the - `WEXITSTATUS' macro. - - `int w_stopsig' - The value of this member is the same as that of the - `WSTOPSIG' macro. - - Instead of accessing these members directly, you should use the - equivalent macros. - - The `wait3' function is the predecessor to `wait4', which is more -flexible. `wait3' is now obsolete. - - - Function: pid_t wait3 (union wait *STATUS-PTR, int OPTIONS, struct - rusage *USAGE) - If USAGE is a null pointer, `wait3' is equivalent to `waitpid (-1, - STATUS-PTR, OPTIONS)'. - - If USAGE is not null, `wait3' stores usage figures for the child - process in `*RUSAGE' (but only if the child has terminated, not if - it has stopped). *Note Resource Usage::. - - -File: libc.info, Node: Process Creation Example, Prev: BSD Wait Functions, Up: Processes - -Process Creation Example -======================== - - Here is an example program showing how you might write a function -similar to the built-in `system'.

That is why, in the -call to `execl', `SHELL' is supplied once to name the program to -execute and a second time to supply a value for `argv[0]'. - - The `execl' call in the child process doesn't return if it is -successful. If it fails, you must do something to make the child -process terminate. Just returning a bad status code with `return' -would leave two processes running the original program. Instead, the -right behavior is for the child process to report failure to its parent -process. - - Call `_exit' to accomplish this. The reason for using `_exit' -instead of `exit' is to avoid flushing fully buffered streams such as -`stdout'. The buffers of these streams probably contain data that was -copied from the parent process by the `fork', data that will be output -eventually by the parent process.

It can do this using the `fork' (*note -Creating a Process::) and `exec' (*note Executing a File::) functions. - - A single command may run just one process--but often one command uses -several processes. If you use the `|' operator in a shell command, you -explicitly request several programs in their own processes. But even -if you run just one program, it can use multiple processes internally. -For example, a single compilation command such as `cc -c foo.c' -typically uses four processes (though normally only two at any given -time). If you run `make', its job is to run other programs in separate -processes. - - The processes belonging to a single command are called a "process -group" or "job". This is so that you can operate on all of them at -once. For example, typing `C-c' sends the signal `SIGINT' to terminate -all the processes in the foreground process group. - - A "session" is a larger group of processes. Normally all the -processes that stem from a single login belong to the same session. - - Every process belongs to a process group. When a process is -created, it becomes a member of the same process group and session as -its parent process. You can put it in another process group using the -`setpgid' function, provided the process group belongs to the same -session. - - The only way to put a process in a different session is to make it -the initial process of a new session, or a "session leader", using the -`setsid' function. This also puts the session leader into a new -process group, and you can't move it out of that process group again. - - Usually, new sessions are created by the system login program, and -the session leader is the process running the user's login shell. - - A shell that supports job control must arrange to control which job -can use the terminal at any time. Otherwise there might be multiple -jobs trying to read from the terminal at once, and confusion about which -process should receive the input typed by the user. To prevent this, -the shell must cooperate with the terminal driver using the protocol -described in this chapter. - - The shell can give unlimited access to the controlling terminal to -only one process group at a time. This is called the "foreground job" -on that controlling terminal. Other process groups managed by the shell -that are executing without such access to the terminal are called -"background jobs". - - If a background job needs to read from its controlling terminal, it -is "stopped" by the terminal driver; if the `TOSTOP' mode is set, -likewise for writing. The user can stop a foreground job by typing the -SUSP character (*note Special Characters::) and a program can stop any -job by sending it a `SIGSTOP' signal. It's the responsibility of the -shell to notice when jobs stop, to notify the user about them, and to -provide mechanisms for allowing the user to interactively continue -stopped jobs and switch jobs between foreground and background. - - *Note Access to the Terminal::, for more information about I/O to the -controlling terminal, - - -File: libc.info, Node: Job Control is Optional, Next: Controlling Terminal, Prev: Concepts of Job Control, Up: Job Control - -Job Control is Optional -======================= - - Not all operating systems support job control. The GNU system does -support job control, but if you are using the GNU library on some other -system, that system may not support job control itself. - - You can use the `_POSIX_JOB_CONTROL' macro to test at compile-time -whether the system supports job control. *Note System Options::. - - If job control is not supported, then there can be only one process -group per session, which behaves as if it were always in the foreground. -The functions for creating additional process groups simply fail with -the error code `ENOSYS'. - - The macros naming the various job control signals (*note Job Control -Signals::) are defined even if job control is not supported. However, -the system never generates these signals, and attempts to send a job -control signal or examine or specify their actions report errors or do -nothing. - - -File: libc.info, Node: Controlling Terminal, Next: Access to the Terminal, Prev: Job Control is Optional, Up: Job Control - -Controlling Terminal of a Process -================================= - - One of the attributes of a process is its controlling terminal. -Child processes created with `fork' inherit the controlling terminal -from their parent process. In this way, all the processes in a session -inherit the controlling terminal from the session leader. A session -leader that has control of a terminal is called the "controlling -process" of that terminal. - - You generally do not need to worry about the exact mechanism used to -allocate a controlling terminal to a session, since it is done for you -by the system when you log in. - - An individual process disconnects from its controlling terminal when -it calls `setsid' to become the leader of a new session. *Note Process -Group Functions::. - - -File: libc.info, Node: Access to the Terminal, Next: Orphaned Process Groups, Prev: Controlling Terminal, Up: Job Control - -Access to the Controlling Terminal -================================== - - Processes in the foreground job of a controlling terminal have -unrestricted access to that terminal; background processes do not. This -section describes in more detail what happens when a process in a -background job tries to access its controlling terminal. - - When a process in a background job tries to read from its controlling -terminal, the process group is usually sent a `SIGTTIN' signal. This -normally causes all of the processes in that group to stop (unless they -handle the signal and don't stop themselves). However, if the reading -process is ignoring or blocking this signal, then `read' fails with an -`EIO' error instead. - - Similarly, when a process in a background job tries to write to its -controlling terminal, the default behavior is to send a `SIGTTOU' -signal to the process group. However, the behavior is modified by the -`TOSTOP' bit of the local modes flags (*note Local Modes::). If this -bit is not set (which is the default), then writing to the controlling -terminal is always permitted without sending a signal. Writing is also -permitted if the `SIGTTOU' signal is being ignored or blocked by the -writing process. - - Most other terminal operations that a program can do are treated as -reading or as writing. (The description of each operation should say -which.) - - For more information about the primitive `read' and `write' -functions, see *Note I/O Primitives::. - - -File: libc.info, Node: Orphaned Process Groups, Next: Implementing a Shell, Prev: Access to the Terminal, Up: Job Control - -Orphaned Process Groups -======================= - - When a controlling process terminates, its terminal becomes free and -a new session can be established on it. (In fact, another user could -log in on the terminal.) This could cause a problem if any processes -from the old session are still trying to use that terminal. - - To prevent problems, process groups that continue running even after -the session leader has terminated are marked as "orphaned process -groups". - - When a process group becomes an orphan, its processes are sent a -`SIGHUP' signal. Ordinarily, this causes the processes to terminate. -However, if a program ignores this signal or establishes a handler for -it (*note Signal Handling::), it can continue running as in the orphan -process group even after its controlling process terminates; but it -still cannot access the terminal any more. - - -File: libc.info, Node: Implementing a Shell, Next: Functions for Job Control, Prev: Orphaned Process Groups, Up: Job Control - -Implementing a Job Control Shell -================================ - - This section describes what a shell must do to implement job -control, by presenting an extensive sample program to illustrate the -concepts involved. - -* Menu: - -* Data Structures:: Introduction to the sample shell. -* Initializing the Shell:: What the shell must do to take - responsibility for job control. -* Launching Jobs:: Creating jobs to execute commands. -* Foreground and Background:: Putting a job in foreground of background. -* Stopped and Terminated Jobs:: Reporting job status. -* Continuing Stopped Jobs:: How to continue a stopped job in - the foreground or background. -* Missing Pieces:: Other parts of the shell. - - -File: libc.info, Node: Data Structures, Next: Initializing the Shell, Up: Implementing a Shell - -Data Structures for the Shell ------------------------------ - - All of the program examples included in this chapter are part of a -simple shell program. This section presents data structures and -utility functions which are used throughout the example. - - The sample shell deals mainly with two data structures. The `job' -type contains information about a job, which is a set of subprocesses -linked together with pipes. The `process' type holds information about -a single subprocess. Here are the relevant data structure declarations: - - /* A process is a single process. */ - typedef struct process - { - struct process *next; /* next process in pipeline */ - char **argv; /* for exec */ - pid_t pid; /* process ID */ - char completed; /* true if process has completed */ - char stopped; /* true if process has stopped */ - int status; /* reported status value */ - } process; - - /* A job is a pipeline of processes. */ - typedef struct job - { - struct job *next; /* next active job */ - char *command; /* command line, used for messages */ - process *first_process; /* list of processes in this job */ - pid_t pgid; /* process group ID */ - char notified; /* true if user told about stopped job */ - struct termios tmodes; /* saved terminal modes */ - int stdin, stdout, stderr; /* standard i/o channels */ - } job; - - /* The active jobs are linked into a list. This is its head. */ - job *first_job = NULL; - - Here are some utility functions that are used for operating on `job' -objects. - - /* Find the active job with the indicated PGID. */ - job * - find_job (pid_t pgid) - { - job *j; - - for (j = first_job; j; j = j->next) - if (j->pgid == pgid) - return j; - return NULL; - } - - /* Return true if all processes in the job have stopped or completed. */ - int - job_is_stopped (job *j) - { - process *p; - - for (p = j->first_process; p; p = p->next) - if (!p->completed && !p->stopped) - return 0; - return 1; - } - - /* Return true if all processes in the job have completed. */ - int - job_is_completed (job *j) - { - process *p; - - for (p = j->first_process; p; p = p->next) - if (!p->completed) - return 0; - return 1; - } - - -File: libc.info, Node: Initializing the Shell, Next: Launching Jobs, Prev: Data Structures, Up: Implementing a Shell - -Initializing the Shell ----------------------- - - When a shell program that normally performs job control is started, -it has to be careful in case it has been invoked from another shell -that is already doing its own job control. - - A subshell that runs interactively has to ensure that it has been -placed in the foreground by its parent shell before it can enable job -control itself. It does this by getting its initial process group ID -with the `getpgrp' function, and comparing it to the process group ID -of the current foreground job associated with its controlling terminal -(which can be retrieved using the `tcgetpgrp' function). - - If the subshell is not running as a foreground job, it must stop -itself by sending a `SIGTTIN' signal to its own process group. It may -not arbitrarily put itself into the foreground; it must wait for the -user to tell the parent shell to do this. If the subshell is continued -again, it should repeat the check and stop itself again if it is still -not in the foreground. - - Once the subshell has been placed into the foreground by its parent -shell, it can enable its own job control. It does this by calling -`setpgid' to put itself into its own process group, and then calling -`tcsetpgrp' to place this process group into the foreground. - - When a shell enables job control, it should set itself to ignore all -the job control stop signals so that it doesn't accidentally stop -itself. You can do this by setting the action for all the stop signals -to `SIG_IGN'. - - A subshell that runs non-interactively cannot and should not support -job control. It must leave all processes it creates in the same process -group as the shell itself; this allows the non-interactive shell and its -child processes to be treated as a single job by the parent shell. This -is easy to do--just don't use any of the job control primitives--but -you must remember to make the shell do it. - - Here is the initialization code for the sample shell that shows how -to do all of this. - - /* Keep track of attributes of the shell. */ - - #include - #include - #include - - pid_t shell_pgid; - struct termios shell_tmodes; - int shell_terminal; - int shell_is_interactive; - - - /* Make sure the shell is running interactively as the foreground job - before proceeding. */ - - void - init_shell () - { - - /* See if we are running interactively. */ - shell_terminal = STDIN_FILENO; - shell_is_interactive = isatty (shell_terminal); - - if (shell_is_interactive) - { - /* Loop until we are in the foreground. */ - while (tcgetpgrp (shell_terminal) != (shell_pgid = getpgrp ())) - kill (- shell_pgid, SIGTTIN); - - /* Ignore interactive and job-control signals. */ - signal (SIGINT, SIG_IGN); - signal (SIGQUIT, SIG_IGN); - signal (SIGTSTP, SIG_IGN); - signal (SIGTTIN, SIG_IGN); - signal (SIGTTOU, SIG_IGN); - signal (SIGCHLD, SIG_IGN); - - /* Put ourselves in our own process group. */ - shell_pgid = getpid (); - if (setpgid (shell_pgid, shell_pgid) < 0) - { - perror ("Couldn't put the shell in its own process group"); - exit (1); - } - - /* Grab control of the terminal. */ - tcsetpgrp (shell_terminal, shell_pgid); - - /* Save default terminal attributes for shell. */ - tcgetattr (shell_terminal, &shell_tmodes); - } - } - - -File: libc.info, Node: Launching Jobs, Next: Foreground and Background, Prev: Initializing the Shell, Up: Implementing a Shell - -Launching Jobs --------------- - - Once the shell has taken responsibility for performing job control on -its controlling terminal, it can launch jobs in response to commands -typed by the user. - - To create the processes in a process group, you use the same `fork' -and `exec' functions described in *Note Process Creation Concepts::. -Since there are multiple child processes involved, though, things are a -little more complicated and you must be careful to do things in the -right order. Otherwise, nasty race conditions can result. - - You have two choices for how to structure the tree of parent-child -relationships among the processes. You can either make all the -processes in the process group be children of the shell process, or you -can make one process in group be the ancestor of all the other processes -in that group. The sample shell program presented in this chapter uses -the first approach because it makes bookkeeping somewhat simpler. - - As each process is forked, it should put itself in the new process -group by calling `setpgid'; see *Note Process Group Functions::. The -first process in the new group becomes its "process group leader", and -its process ID becomes the "process group ID" for the group. - - The shell should also call `setpgid' to put each of its child -processes into the new process group. This is because there is a -potential timing problem: each child process must be put in the process -group before it begins executing a new program, and the shell depends on -having all the child processes in the group before it continues -executing. If both the child processes and the shell call `setpgid', -this ensures that the right things happen no matter which process gets -to it first. - - If the job is being launched as a foreground job, the new process -group also needs to be put into the foreground on the controlling -terminal using `tcsetpgrp'. Again, this should be done by the shell as -well as by each of its child processes, to avoid race conditions. - - The next thing each child process should do is to reset its signal -actions. - - During initialization, the shell process set itself to ignore job -control signals; see *Note Initializing the Shell::. As a result, any -child processes it creates also ignore these signals by inheritance. -This is definitely undesirable, so each child process should explicitly -set the actions for these signals back to `SIG_DFL' just after it is -forked. - - Since shells follow this convention, applications can assume that -they inherit the correct handling of these signals from the parent -process. But every application has a responsibility not to mess up the -handling of stop signals. Applications that disable the normal -interpretation of the SUSP character should provide some other -mechanism for the user to stop the job. When the user invokes this -mechanism, the program should send a `SIGTSTP' signal to the process -group of the process, not just to the process itself. *Note Signaling -Another Process::. - - Finally, each child process should call `exec' in the normal way. -This is also the point at which redirection of the standard input and -output channels should be handled. *Note Duplicating Descriptors::, -for an explanation of how to do this. - - Here is the function from the sample shell program that is -responsible for launching a program. The function is executed by each -child process immediately after it has been forked by the shell, and -never returns. - - void - launch_process (process *p, pid_t pgid, - int infile, int outfile, int errfile, - int foreground) - { - pid_t pid; - - if (shell_is_interactive) - { - /* Put the process into the process group and give the process group - the terminal, if appropriate. - This has to be done both by the shell and in the individual - child processes because of potential race conditions. */ - pid = getpid (); - if (pgid == 0) pgid = pid; - setpgid (pid, pgid); - if (foreground) - tcsetpgrp (shell_terminal, pgid); - - /* Set the handling for job control signals back to the default. */ - signal (SIGINT, SIG_DFL); - signal (SIGQUIT, SIG_DFL); - signal (SIGTSTP, SIG_DFL); - signal (SIGTTIN, SIG_DFL); - signal (SIGTTOU, SIG_DFL); - signal (SIGCHLD, SIG_DFL); - } - - /* Set the standard input/output channels of the new process. */ - if (infile != STDIN_FILENO) - { - dup2 (infile, STDIN_FILENO); - close (infile); - } - if (outfile != STDOUT_FILENO) - { - dup2 (outfile, STDOUT_FILENO); - close (outfile); - } - if (errfile != STDERR_FILENO) - { - dup2 (errfile, STDERR_FILENO); - close (errfile); - } - - /* Exec the new process. Make sure we exit. */ - execvp (p->argv[0], p->argv); - perror ("execvp"); - exit (1); - } - - If the shell is not running interactively, this function does not do -anything with process groups or signals. Remember that a shell not -performing job control must keep all of its subprocesses in the same -process group as the shell itself. - - Next, here is the function that actually launches a complete job. -After creating the child processes, this function calls some other -functions to put the newly created job into the foreground or -background; these are discussed in *Note Foreground and Background::. - - void - launch_job (job *j, int foreground) - { - process *p; - pid_t pid; - int mypipe[2], infile, outfile; - - infile = j->stdin; - for (p = j->first_process; p; p = p->next) - { - /* Set up pipes, if necessary. */ - if (p->next) - { - if (pipe (mypipe) < 0) - { - perror ("pipe"); - exit (1); - } - outfile = mypipe[1]; - } - else - outfile = j->stdout; - - /* Fork the child processes. */ - pid = fork (); - if (pid == 0) - /* This is the child process. */ - launch_process (p, j->pgid, infile, - outfile, j->stderr, foreground); - else if (pid < 0) - { - /* The fork failed. */ - perror ("fork"); - exit (1); - } - else - { - /* This is the parent process. */ - p->pid = pid; - if (shell_is_interactive) - { - if (!j->pgid) - j->pgid = pid; - setpgid (pid, j->pgid); - } - } - - /* Clean up after pipes. */ - if (infile != j->stdin) - close (infile); - if (outfile != j->stdout) - close (outfile); - infile = mypipe[0]; - } - - format_job_info (j, "launched"); - - if (!shell_is_interactive) - wait_for_job (j); - else if (foreground) - put_job_in_foreground (j, 0); - else - put_job_in_background (j, 0); - } - - -File: libc.info, Node: Foreground and Background, Next: Stopped and Terminated Jobs, Prev: Launching Jobs, Up: Implementing a Shell - -Foreground and Background -------------------------- - - Now let's consider what actions must be taken by the shell when it -launches a job into the foreground, and how this differs from what must -be done when a background job is launched. - - When a foreground job is launched, the shell must first give it -access to the controlling terminal by calling `tcsetpgrp'. Then, the -shell should wait for processes in that process group to terminate or -stop. This is discussed in more detail in *Note Stopped and Terminated -Jobs::. - - When all of the processes in the group have either completed or -stopped, the shell should regain control of the terminal for its own -process group by calling `tcsetpgrp' again. Since stop signals caused -by I/O from a background process or a SUSP character typed by the user -are sent to the process group, normally all the processes in the job -stop together. - - The foreground job may have left the terminal in a strange state, so -the shell should restore its own saved terminal modes before -continuing. In case the job is merely stopped, the shell should first -save the current terminal modes so that it can restore them later if -the job is continued. The functions for dealing with terminal modes are -`tcgetattr' and `tcsetattr'; these are described in *Note Terminal -Modes::. - - Here is the sample shell's function for doing all of this. - - /* Put job J in the foreground. If CONT is nonzero, - restore the saved terminal modes and send the process group a - `SIGCONT' signal to wake it up before we block. */ - - void - put_job_in_foreground (job *j, int cont) - { - /* Put the job into the foreground. */ - tcsetpgrp (shell_terminal, j->pgid); - - /* Send the job a continue signal, if necessary. */ - if (cont) - { - tcsetattr (shell_terminal, TCSADRAIN, &j->tmodes); - if (kill (- j->pgid, SIGCONT) < 0) - perror ("kill (SIGCONT)"); - } - - /* Wait for it to report. */ - wait_for_job (j); - - /* Put the shell back in the foreground. */ - tcsetpgrp (shell_terminal, shell_pgid); - - /* Restore the shell's terminal modes. */ - tcgetattr (shell_terminal, &j->tmodes); - tcsetattr (shell_terminal, TCSADRAIN, &shell_tmodes); - } - - If the process group is launched as a background job, the shell -should remain in the foreground itself and continue to read commands -from the terminal. - - In the sample shell, there is not much that needs to be done to put -a job into the background. Here is the function it uses: - - /* Put a job in the background. If the cont argument is true, send - the process group a `SIGCONT' signal to wake it up. */ - - void - put_job_in_background (job *j, int cont) - { - /* Send the job a continue signal, if necessary. */ - if (cont) - if (kill (-j->pgid, SIGCONT) < 0) - perror ("kill (SIGCONT)"); - } - diff -u -udbrN glibc-2.3.2/manual/libc.info-45 glibc-2.3.2-200304020432/manual/libc.info-45 --- glibc-2.3.2/manual/libc.info-45 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-45 Thu Jan 1 01:00:00 1970 @@ -1,1245 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

Your program should include the header files `sys/types.h' and -`unistd.h' to use these functions. - - - Function: pid_t setsid (void) - The `setsid' function creates a new session. The calling process - becomes the session leader, and is put in a new process group whose - process group ID is the same as the process ID of that process. - There are initially no other processes in the new process group, - and no other process groups in the new session. - - This function also makes the calling process have no controlling - terminal. - - The `setsid' function returns the new process group ID of the - calling process if successful. A return value of `-1' indicates an - error. The following `errno' error conditions are defined for this - function: - - `EPERM' - The calling process is already a process group leader, or - there is already another process group around that has the - same process group ID. - - - Function: pid_t getsid (pid_t PID) - The `getsid' function returns the process group ID of the session - leader of the specified process. If a PID is `0', the process - group ID of the session leader of the current process is returned. - - In case of error `-1' is returned and `errno' is set. The - following `errno' error conditions are defined for this function: - - `ESRCH' - There is no process with the given process ID PID. - - `EPERM' - The calling process and the process specified by PID are in - different sessions, and the implementation doesn't allow to - access the process group ID of the session leader of the - process with ID PID from the calling process. - - The `getpgrp' function has two definitions: one derived from BSD -Unix, and one from the POSIX.1 standard. The feature test macros you -have selected (*note Feature Test Macros::) determine which definition -you get. Specifically, you get the BSD version if you define -`_BSD_SOURCE'; otherwise, you get the POSIX version if you define -`_POSIX_SOURCE' or `_GNU_SOURCE'. Programs written for old BSD systems -will not include `unistd.h', which defines `getpgrp' specially under -`_BSD_SOURCE'. You must link such programs with the `-lbsd-compat' -option to get the BSD definition. - - - POSIX.1 Function: pid_t getpgrp (void) - The POSIX.1 definition of `getpgrp' returns the process group ID of - the calling process. - - - BSD Function: pid_t getpgrp (pid_t PID) - The BSD definition of `getpgrp' returns the process group ID of the - process PID. You can supply a value of `0' for the PID argument - to get information about the calling process. - - - System V Function: int getpgid (pid_t PID) - `getpgid' is the same as the BSD function `getpgrp'. It returns - the process group ID of the process PID. You can supply a value - of `0' for the PID argument to get information about the calling - process. - - In case of error `-1' is returned and `errno' is set. The - following `errno' error conditions are defined for this function: - - `ESRCH' - There is no process with the given process ID PID. The - calling process and the process specified by PID are in - different sessions, and the implementation doesn't allow to - access the process group ID of the process with ID PID from - the calling process. - - - Function: int setpgid (pid_t PID, pid_t PGID) - The `setpgid' function puts the process PID into the process group - PGID. As a special case, either PID or PGID can be zero to - indicate the process ID of the calling process. - - This function fails on a system that does not support job control. - *Note Job Control is Optional::, for more information. - - If the operation is successful, `setpgid' returns zero. Otherwise - it returns `-1'. The following `errno' error conditions are - defined for this function: - - `EACCES' - The child process named by PID has executed an `exec' - function since it was forked. - - `EINVAL' - The value of the PGID is not valid. - - `ENOSYS' - The system doesn't support job control. - - `EPERM' - The process indicated by the PID argument is a session leader, - or is not in the same session as the calling process, or the - value of the PGID argument doesn't match a process group ID - in the same session as the calling process. - - `ESRCH' - The process indicated by the PID argument is not the calling - process or a child of the calling process. - - - Function: int setpgrp (pid_t PID, pid_t PGID) - This is the BSD Unix name for `setpgid'. Both functions do exactly - the same thing. - - -File: libc.info, Node: Terminal Access Functions, Prev: Process Group Functions, Up: Functions for Job Control - -Functions for Controlling Terminal Access ------------------------------------------ - - These are the functions for reading or setting the foreground -process group of a terminal. You should include the header files -`sys/types.h' and `unistd.h' in your application to use these functions. - - Although these functions take a file descriptor argument to specify -the terminal device, the foreground job is associated with the terminal -file itself and not a particular open file descriptor. - - - Function: pid_t tcgetpgrp (int FILEDES) - This function returns the process group ID of the foreground - process group associated with the terminal open on descriptor - FILEDES. - - If there is no foreground process group, the return value is a - number greater than `1' that does not match the process group ID - of any existing process group. This can happen if all of the - processes in the job that was formerly the foreground job have - terminated, and no other job has yet been moved into the - foreground. - - In case of an error, a value of `-1' is returned. The following - `errno' error conditions are defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `ENOSYS' - The system doesn't support job control. - - `ENOTTY' - The terminal file associated with the FILEDES argument isn't - the controlling terminal of the calling process. - - - Function: int tcsetpgrp (int FILEDES, pid_t PGID) - This function is used to set a terminal's foreground process group - ID. The argument FILEDES is a descriptor which specifies the - terminal; PGID specifies the process group. The calling process - must be a member of the same session as PGID and must have the same - controlling terminal. - - For terminal access purposes, this function is treated as output. - If it is called from a background process on its controlling - terminal, normally all processes in the process group are sent a - `SIGTTOU' signal. The exception is if the calling process itself - is ignoring or blocking `SIGTTOU' signals, in which case the - operation is performed and no signal is sent. - - If successful, `tcsetpgrp' returns `0'. A return value of `-1' - indicates an error. The following `errno' error conditions are - defined for this function: - - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `EINVAL' - The PGID argument is not valid. - - `ENOSYS' - The system doesn't support job control. - - `ENOTTY' - The FILEDES isn't the controlling terminal of the calling - process. - - `EPERM' - The PGID isn't a process group in the same session as the - calling process. - - - Function: pid_t tcgetsid (int FILDES) - This function is used to obtain the process group ID of the session - for which the terminal specified by FILDES is the controlling - terminal. If the call is successful the group ID is returned. - Otherwise the return value is `(pid_t) -1' and the global variable - ERRNO is set to the following value: - `EBADF' - The FILEDES argument is not a valid file descriptor. - - `ENOTTY' - The calling process does not have a controlling terminal, or - the file is not the controlling terminal. - - -File: libc.info, Node: Name Service Switch, Next: Users and Groups, Prev: Job Control, Up: Top - -System Databases and Name Service Switch -**************************************** - - Various functions in the C Library need to be configured to work -correctly in the local environment. Traditionally, this was done by -using files (e.g., `/etc/passwd'), but other nameservices (like the -Network Information Service (NIS) and the Domain Name Service (DNS)) -became popular, and were hacked into the C library, usually with a fixed -search order (*note frobnicate: (jargon)frobnicate.). - - The GNU C Library contains a cleaner solution of this problem. It is -designed after a method used by Sun Microsystems in the C library of -Solaris 2. GNU C Library follows their name and calls this scheme -"Name Service Switch" (NSS). - - Though the interface might be similar to Sun's version there is no -common code. We never saw any source code of Sun's implementation and -so the internal interface is incompatible. This also manifests in the -file names we use as we will see later. - -* Menu: - -* NSS Basics:: What is this NSS good for. -* NSS Configuration File:: Configuring NSS. -* NSS Module Internals:: How does it work internally. -* Extending NSS:: What to do to add services or databases. - - -File: libc.info, Node: NSS Basics, Next: NSS Configuration File, Prev: Name Service Switch, Up: Name Service Switch - -NSS Basics -========== - - The basic idea is to put the implementation of the different services -offered to access the databases in separate modules. This has some -advantages: - - 1. Contributors can add new services without adding them to GNU C - Library. - - 2. The modules can be updated separately. - - 3. The C library image is smaller. - - To fulfill the first goal above the ABI of the modules will be -described below. For getting the implementation of a new service right -it is important to understand how the functions in the modules get -called. They are in no way designed to be used by the programmer -directly. Instead the programmer should only use the documented and -standardized functions to access the databases. - -The databases available in the NSS are - -`aliases' - Mail aliases - -`ethers' - Ethernet numbers, - -`group' - Groups of users, *note Group Database::. - -`hosts' - Host names and numbers, *note Host Names::. - -`netgroup' - Network wide list of host and users, *note Netgroup Database::. - -`networks' - Network names and numbers, *note Networks Database::. - -`protocols' - Network protocols, *note Protocols Database::. - -`passwd' - User passwords, *note User Database::. - -`rpc' - Remote procedure call names and numbers, - -`services' - Network services, *note Services Database::. - -`shadow' - Shadow user passwords, - -There will be some more added later (`automount', `bootparams', -`netmasks', and `publickey'). - - -File: libc.info, Node: NSS Configuration File, Next: NSS Module Internals, Prev: NSS Basics, Up: Name Service Switch - -The NSS Configuration File -========================== - - Somehow the NSS code must be told about the wishes of the user. For -this reason there is the file `/etc/nsswitch.conf'. For each database -this file contain a specification how the lookup process should work. -The file could look like this: - - # /etc/nsswitch.conf - # - # Name Service Switch configuration file. - # - - passwd: db files nis - shadow: files - group: db files nis - - hosts: files nisplus nis dns - networks: nisplus [NOTFOUND=return] files - - ethers: nisplus [NOTFOUND=return] db files - protocols: nisplus [NOTFOUND=return] db files - rpc: nisplus [NOTFOUND=return] db files - services: nisplus [NOTFOUND=return] db files - - The first column is the database as you can guess from the table -above. The rest of the line specifies how the lookup process works. -Please note that you specify the way it works for each database -individually. This cannot be done with the old way of a monolithic -implementation. - - The configuration specification for each database can contain two -different items: - - * the service specification like `files', `db', or `nis'. - - * the reaction on lookup result like `[NOTFOUND=return]'. - -* Menu: - -* Services in the NSS configuration:: Service names in the NSS configuration. -* Actions in the NSS configuration:: React appropriately to the lookup result. -* Notes on NSS Configuration File:: Things to take care about while - configuring NSS. - - -File: libc.info, Node: Services in the NSS configuration, Next: Actions in the NSS configuration, Prev: NSS Configuration File, Up: NSS Configuration File - -Services in the NSS configuration File --------------------------------------- - - The above example file mentions four different services: `files', -`db', `nis', and `nisplus'. This does not mean these services are -available on all sites and it does also not mean these are all the -services which will ever be available. - - In fact, these names are simply strings which the NSS code uses to -find the implicitly addressed functions. The internal interface will be -described later. Visible to the user are the modules which implement an -individual service. - - Assume the service NAME shall be used for a lookup. The code for -this service is implemented in a module called `libnss_NAME'. On a -system supporting shared libraries this is in fact a shared library -with the name (for example) `libnss_NAME.so.2'. The number at the end -is the currently used version of the interface which will not change -frequently. Normally the user should not have to be cognizant of these -files since they should be placed in a directory where they are found -automatically. Only the names of all available services are important. - - -File: libc.info, Node: Actions in the NSS configuration, Next: Notes on NSS Configuration File, Prev: Services in the NSS configuration, Up: NSS Configuration File - -Actions in the NSS configuration --------------------------------- - - The second item in the specification gives the user much finer -control on the lookup process. Action items are placed between two -service names and are written within brackets. The general form is - - `[' ( `!'? STATUS `=' ACTION )+ `]' - -where - - STATUS => success | notfound | unavail | tryagain - ACTION => return | continue - - The case of the keywords is insignificant. The STATUS values are -the results of a call to a lookup function of a specific service. They -mean - -`success' - No error occurred and the wanted entry is returned. The default - action for this is `return'. - -`notfound' - The lookup process works ok but the needed value was not found. - The default action is `continue'. - -`unavail' - The service is permanently unavailable. This can either mean the - needed file is not available, or, for DNS, the server is not - available or does not allow queries. The default action is - `continue'. - -`tryagain' - The service is temporarily unavailable. This could mean a file is - locked or a server currently cannot accept more connections. The - default action is `continue'. - -If we have a line like - - ethers: nisplus [NOTFOUND=return] db files - -this is equivalent to - - ethers: nisplus [SUCCESS=return NOTFOUND=return UNAVAIL=continue - TRYAGAIN=continue] - db [SUCCESS=return NOTFOUND=continue UNAVAIL=continue - TRYAGAIN=continue] - files - -(except that it would have to be written on one line). The default -value for the actions are normally what you want, and only need to be -changed in exceptional cases. - - If the optional `!' is placed before the STATUS this means the -following action is used for all statuses but STATUS itself. I.e., `!' -is negation as in the C language (and others). - - Before we explain the exception which makes this action item -necessary one more remark: obviously it makes no sense to add another -action item after the `files' service. Since there is no other service -following the action _always_ is `return'. - - Now, why is this `[NOTFOUND=return]' action useful? To understand -this we should know that the `nisplus' service is often complete; i.e., -if an entry is not available in the NIS+ tables it is not available -anywhere else. This is what is expressed by this action item: it is -useless to examine further services since they will not give us a -result. - - The situation would be different if the NIS+ service is not available -because the machine is booting. In this case the return value of the -lookup function is not `notfound' but instead `unavail'. And as you -can see in the complete form above: in this situation the `db' and -`files' services are used. Neat, isn't it? The system administrator -need not pay special care for the time the system is not completely -ready to work (while booting or shutdown or network problems). - - -File: libc.info, Node: Notes on NSS Configuration File, Prev: Actions in the NSS configuration, Up: NSS Configuration File - -Notes on the NSS Configuration File ------------------------------------ - - Finally a few more hints. The NSS implementation is not completely -helpless if `/etc/nsswitch.conf' does not exist. For all supported -databases there is a default value so it should normally be possible to -get the system running even if the file is corrupted or missing. - - For the `hosts' and `networks' databases the default value is `dns -[!UNAVAIL=return] files'. I.e., the system is prepared for the DNS -service not to be available but if it is available the answer it -returns is definitive. - - The `passwd', `group', and `shadow' databases are traditionally -handled in a special way. The appropriate files in the `/etc' -directory are read but if an entry with a name starting with a `+' -character is found NIS is used. This kind of lookup remains possible -by using the special lookup service `compat' and the default value for -the three databases above is `compat [NOTFOUND=return] files'. - - For all other databases the default value is `nis [NOTFOUND=return] -files'. This solution give the best chance to be correct since NIS and -file based lookup is used. - - A second point is that the user should try to optimize the lookup -process. The different service have different response times. A -simple file look up on a local file could be fast, but if the file is -long and the needed entry is near the end of the file this may take -quite some time. In this case it might be better to use the `db' -service which allows fast local access to large data sets. - - Often the situation is that some global information like NIS must be -used. So it is unavoidable to use service entries like `nis' etc. But -one should avoid slow services like this if possible. - - -File: libc.info, Node: NSS Module Internals, Next: Extending NSS, Prev: NSS Configuration File, Up: Name Service Switch - -NSS Module Internals -==================== - - Now it is time to describe what the modules look like. The functions -contained in a module are identified by their names. I.e., there is no -jump table or the like. How this is done is of no interest here; those -interested in this topic should read about Dynamic Linking. - -* Menu: - -* NSS Module Names:: Construction of the interface function of - the NSS modules. -* NSS Modules Interface:: Programming interface in the NSS module - functions. - - -File: libc.info, Node: NSS Module Names, Next: NSS Modules Interface, Prev: NSS Module Internals, Up: NSS Module Internals - -The Naming Scheme of the NSS Modules ------------------------------------- - -The name of each function consist of various parts: - - _nss_SERVICE_FUNCTION - - SERVICE of course corresponds to the name of the module this -function is found in.(1) The FUNCTION part is derived from the -interface function in the C library itself. If the user calls the -function `gethostbyname' and the service used is `files' the function - - _nss_files_gethostbyname_r - -in the module - - libnss_files.so.2 - -is used. You see, what is explained above in not the whole truth. In -fact the NSS modules only contain reentrant versions of the lookup -functions. I.e., if the user would call the `gethostbyname_r' function -this also would end in the above function. For all user interface -functions the C library maps this call to a call to the reentrant -function. For reentrant functions this is trivial since the interface -is (nearly) the same. For the non-reentrant version The library keeps -internal buffers which are used to replace the user supplied buffer. - - I.e., the reentrant functions _can_ have counterparts. No service -module is forced to have functions for all databases and all kinds to -access them. If a function is not available it is simply treated as if -the function would return `unavail' (*note Actions in the NSS -configuration::). - - The file name `libnss_files.so.2' would be on a Solaris 2 system -`nss_files.so.2'. This is the difference mentioned above. Sun's NSS -modules are usable as modules which get indirectly loaded only. - - The NSS modules in the GNU C Library are prepared to be used as -normal libraries themselves. This is _not_ true at the moment, though. -However, the organization of the name space in the modules does not -make it impossible like it is for Solaris. Now you can see why the -modules are still libraries.(2) - - ---------- Footnotes ---------- - - (1) Now you might ask why this information is duplicated. The -answer is that we want to make it possible to link directly with these -shared objects. - - (2) There is a second explanation: we were too lazy to change the -Makefiles to allow the generation of shared objects not starting with -`lib' but don't tell this to anybody. - - -File: libc.info, Node: NSS Modules Interface, Prev: NSS Module Names, Up: NSS Module Internals - -The Interface of the Function in NSS Modules --------------------------------------------- - - Now we know about the functions contained in the modules. It is now -time to describe the types. When we mentioned the reentrant versions of -the functions above, this means there are some additional arguments -(compared with the standard, non-reentrant version). The prototypes for -the non-reentrant and reentrant versions of our function above are: - - struct hostent *gethostbyname (const char *name) - - int gethostbyname_r (const char *name, struct hostent *result_buf, - char *buf, size_t buflen, struct hostent **result, - int *h_errnop) - -The actual prototype of the function in the NSS modules in this case is - - enum nss_status _nss_files_gethostbyname_r (const char *name, - struct hostent *result_buf, - char *buf, size_t buflen, - int *errnop, int *h_errnop) - - I.e., the interface function is in fact the reentrant function with -the change of the return value and the omission of the RESULT -parameter. While the user-level function returns a pointer to the -result the reentrant function return an `enum nss_status' value: - -`NSS_STATUS_TRYAGAIN' - numeric value `-2' - -`NSS_STATUS_UNAVAIL' - numeric value `-1' - -`NSS_STATUS_NOTFOUND' - numeric value `0' - -`NSS_STATUS_SUCCESS' - numeric value `1' - -Now you see where the action items of the `/etc/nsswitch.conf' file are -used. - - If you study the source code you will find there is a fifth value: -`NSS_STATUS_RETURN'. This is an internal use only value, used by a few -functions in places where none of the above value can be used. If -necessary the source code should be examined to learn about the details. - - In case the interface function has to return an error it is important -that the correct error code is stored in `*ERRNOP'. Some return status -value have only one associated error code, others have more. - -`NSS_STATUS_TRYAGAIN' `EAGAIN' One of the functions used ran - temporarily out of resources or a - service is currently not available. - `ERANGE' The provided buffer is not large - enough. The function should be - called again with a larger buffer. -`NSS_STATUS_UNAVAIL' `ENOENT' A necessary input file cannot be - found. -`NSS_STATUS_NOTFOUND' `ENOENT' The requested entry is not - available. - - These are proposed values. There can be other error codes and the -described error codes can have different meaning. *With one -exception:* when returning `NSS_STATUS_TRYAGAIN' the error code -`ERANGE' _must_ mean that the user provided buffer is too small. -Everything is non-critical. - - The above function has something special which is missing for almost -all the other module functions. There is an argument H_ERRNOP. This -points to a variable which will be filled with the error code in case -the execution of the function fails for some reason. The reentrant -function cannot use the global variable H_ERRNO; `gethostbyname' calls -`gethostbyname_r' with the last argument set to `&h_errno'. - - The `getXXXbyYYY' functions are the most important functions in the -NSS modules. But there are others which implement the other ways to -access system databases (say for the password database, there are -`setpwent', `getpwent', and `endpwent'). These will be described in -more detail later. Here we give a general way to determine the -signature of the module function: - - * the return value is `int'; - - * the name is as explained in *note NSS Module Names::; - - * the first arguments are identical to the arguments of the - non-reentrant function; - - * the next three arguments are: - - `STRUCT_TYPE *result_buf' - pointer to buffer where the result is stored. `STRUCT_TYPE' - is normally a struct which corresponds to the database. - - `char *buffer' - pointer to a buffer where the function can store additional - data for the result etc. - - `size_t buflen' - length of the buffer pointed to by BUFFER. - - * possibly a last argument H_ERRNOP, for the host name and network - name lookup functions. - -This table is correct for all functions but the `set...ent' and -`end...ent' functions. - - -File: libc.info, Node: Extending NSS, Prev: NSS Module Internals, Up: Name Service Switch - -Extending NSS -============= - - One of the advantages of NSS mentioned above is that it can be -extended quite easily. There are two ways in which the extension can -happen: adding another database or adding another service. The former -is normally done only by the C library developers. It is here only -important to remember that adding another database is independent from -adding another service because a service need not support all databases -or lookup functions. - - A designer/implementor of a new service is therefore free to choose -the databases s/he is interested in and leave the rest for later (or -completely aside). - -* Menu: - -* Adding another Service to NSS:: What is to do to add a new service. -* NSS Module Function Internals:: Guidelines for writing new NSS - service functions. - - -File: libc.info, Node: Adding another Service to NSS, Next: NSS Module Function Internals, Prev: Extending NSS, Up: Extending NSS - -Adding another Service to NSS ------------------------------ - - The sources for a new service need not (and should not) be part of -the GNU C Library itself. The developer retains complete control over -the sources and its development. The links between the C library and -the new service module consists solely of the interface functions. - - Each module is designed following a specific interface specification. -For now the version is 2 (the interface in version 1 was not adequate) -and this manifests in the version number of the shared library object of -the NSS modules: they have the extension `.2'. If the interface -changes again in an incompatible way, this number will be increased. -Modules using the old interface will still be usable. - - Developers of a new service will have to make sure that their module -is created using the correct interface number. This means the file -itself must have the correct name and on ELF systems the "soname" -(Shared Object Name) must also have this number. Building a module -from a bunch of object files on an ELF system using GNU CC could be -done like this: - - gcc -shared -o libnss_NAME.so.2 -Wl,-soname,libnss_NAME.so.2 OBJECTS - -*Note Options for Linking: (gcc)Link Options, to learn more about this -command line. - - To use the new module the library must be able to find it. This can -be achieved by using options for the dynamic linker so that it will -search the directory where the binary is placed. For an ELF system -this could be done by adding the wanted directory to the value of -`LD_LIBRARY_PATH'. - - But this is not always possible since some programs (those which run -under IDs which do not belong to the user) ignore this variable. -Therefore the stable version of the module should be placed into a -directory which is searched by the dynamic linker.

In fact there is not much more we can say since the -implementation obviously is different for each function. But a few -general rules must be followed by all functions. - - In fact there are four kinds of different functions which may appear -in the interface. All derive from the traditional ones for system -databases. DB in the following table is normally an abbreviation for -the database (e.g., it is `pw' for the password database). - -`enum nss_status _nss_DATABASE_setDBent (void)' - This function prepares the service for following operations. For a - simple file based lookup this means files could be opened, for - other services this function simply is a noop. - - One special case for this function is that it takes an additional - argument for some DATABASEs (i.e., the interface is `int setDBent - (int)'). *Note Host Names::, which describes the `sethostent' - function. - - The return value should be NSS_STATUS_SUCCESS or according to the - table above in case of an error (*note NSS Modules Interface::). - -`enum nss_status _nss_DATABASE_endDBent (void)' - This function simply closes all files which are still open or - removes buffer caches. If there are no files or buffers to remove - this is again a simple noop. - - There normally is no return value different to NSS_STATUS_SUCCESS. - -`enum nss_status _nss_DATABASE_getDBent_r (STRUCTURE *result, char *buffer, size_t buflen, int *errnop)' - Since this function will be called several times in a row to - retrieve one entry after the other it must keep some kind of - state. But this also means the functions are not really - reentrant. They are reentrant only in that simultaneous calls to - this function will not try to write the retrieved data in the same - place (as it would be the case for the non-reentrant functions); - instead, it writes to the structure pointed to by the RESULT - parameter. But the calls share a common state and in the case of - a file access this means they return neighboring entries in the - file. - - The buffer of length BUFLEN pointed to by BUFFER can be used for - storing some additional data for the result. It is _not_ - guaranteed that the same buffer will be passed for the next call - of this function. Therefore one must not misuse this buffer to - save some state information from one call to another. - - Before the function returns the implementation should store the - value of the local ERRNO variable in the variable pointed to be - ERRNOP. This is important to guarantee the module working in - statically linked programs. - - As explained above this function could also have an additional last - argument. This depends on the database used; it happens only for - `host' and `networks'. - - The function shall return `NSS_STATUS_SUCCESS' as long as there are - more entries. When the last entry was read it should return - `NSS_STATUS_NOTFOUND'. When the buffer given as an argument is too - small for the data to be returned `NSS_STATUS_TRYAGAIN' should be - returned. When the service was not formerly initialized by a call - to `_nss_DATABASE_setDBent' all return value allowed for this - function can also be returned here. - -`enum nss_status _nss_DATABASE_getDBbyXX_r (PARAMS, STRUCTURE *result, char *buffer, size_t buflen, int *errnop)' - This function shall return the entry from the database which is - addressed by the PARAMS. The type and number of these arguments - vary. It must be individually determined by looking to the - user-level interface functions. All arguments given to the - non-reentrant version are here described by PARAMS. - - The result must be stored in the structure pointed to by RESULT. - If there is additional data to return (say strings, where the - RESULT structure only contains pointers) the function must use the - BUFFER or length BUFLEN. There must not be any references to - non-constant global data. - - The implementation of this function should honor the STAYOPEN flag - set by the `setDBent' function whenever this makes sense. - - Before the function returns the implementation should store the - value of the local ERRNO variable in the variable pointed to be - ERRNOP. This is important to guarantee the module working in - statically linked programs. - - Again, this function takes an additional last argument for the - `host' and `networks' database. - - The return value should as always follow the rules given above - (*note NSS Modules Interface::). - - -File: libc.info, Node: Users and Groups, Next: System Management, Prev: Name Service Switch, Up: Top - -Users and Groups -**************** - - Every user who can log in on the system is identified by a unique -number called the "user ID".

These IDs determine -the privileges of the process. They are collectively called the -"persona" of the process, because they determine "who it is" for -purposes of access control. - - Your login shell starts out with a persona which consists of your -user ID, your default group ID, and your supplementary group IDs (if -you are in more than one group). In normal circumstances, all your -other processes inherit these values. - - A process also has a "real user ID" which identifies the user who -created the process, and a "real group ID" which identifies that user's -default group. These values do not play a role in access control, so -we do not consider them part of the persona. But they are also -important. - - Both the real and effective user ID can be changed during the -lifetime of a process. *Note Why Change Persona::. - - For details on how a process's effective user ID and group IDs affect -its permission to access files, see *Note Access Permission::. - - The effective user ID of a process also controls permissions for -sending signals using the `kill' function. *Note Signaling Another -Process::. - - Finally, there are many operations which can only be performed by a -process whose effective user ID is zero. A process with this user ID is -a "privileged process". Commonly the user name `root' is associated -with user ID 0, but there may be other user names with this ID. - - -File: libc.info, Node: Why Change Persona, Next: How Change Persona, Prev: Process Persona, Up: Users and Groups - -Why Change the Persona of a Process? -==================================== - - The most obvious situation where it is necessary for a process to -change its user and/or group IDs is the `login' program. When `login' -starts running, its user ID is `root'. Its job is to start a shell -whose user and group IDs are those of the user who is logging in. (To -accomplish this fully, `login' must set the real user and group IDs as -well as its persona. But this is a special case.) - - The more common case of changing persona is when an ordinary user -program needs access to a resource that wouldn't ordinarily be -accessible to the user actually running it. - - For example, you may have a file that is controlled by your program -but that shouldn't be read or modified directly by other users, either -because it implements some kind of locking protocol, or because you want -to preserve the integrity or privacy of the information it contains. -This kind of restricted access can be implemented by having the program -change its effective user or group ID to match that of the resource. - - Thus, imagine a game program that saves scores in a file. The game -program itself needs to be able to update this file no matter who is -running it, but if users can write the file without going through the -game, they can give themselves any scores they like. Some people -consider this undesirable, or even reprehensible. It can be prevented -by creating a new user ID and login name (say, `games') to own the -scores file, and make the file writable only by this user. Then, when -the game program wants to update this file, it can change its effective -user ID to be that for `games'. In effect, the program must adopt the -persona of `games' so it can write the scores file. - - -File: libc.info, Node: How Change Persona, Next: Reading Persona, Prev: Why Change Persona, Up: Users and Groups - -How an Application Can Change Persona -===================================== - - The ability to change the persona of a process can be a source of -unintentional privacy violations, or even intentional abuse. Because of -the potential for problems, changing persona is restricted to special -circumstances. - - You can't arbitrarily set your user ID or group ID to anything you -want; only privileged processes can do that. Instead, the normal way -for a program to change its persona is that it has been set up in -advance to change to a particular user or group. This is the function -of the setuid and setgid bits of a file's access mode. *Note -Permission Bits::. - - When the setuid bit of an executable file is on, executing that file -gives the process a third user ID: the "file user ID". This ID is set -to the owner ID of the file. The system then changes the effective -user ID to the file user ID. The real user ID remains as it was. -Likewise, if the setgid bit is on, the process is given a "file group -ID" equal to the group ID of the file, and its effective group ID is -changed to the file group ID. - - If a process has a file ID (user or group), then it can at any time -change its effective ID to its real ID and back to its file ID. -Programs use this feature to relinquish their special privileges except -when they actually need them. This makes it less likely that they can -be tricked into doing something inappropriate with their privileges. - - *Portability Note:* Older systems do not have file IDs. To -determine if a system has this feature, you can test the compiler -define `_POSIX_SAVED_IDS'. (In the POSIX standard, file IDs are known -as saved IDs.) - - *Note File Attributes::, for a more general discussion of file modes -and accessibility. - - -File: libc.info, Node: Reading Persona, Next: Setting User ID, Prev: How Change Persona, Up: Users and Groups - -Reading the Persona of a Process -================================ - - Here are detailed descriptions of the functions for reading the user -and group IDs of a process, both real and effective.

Up to COUNT of these group IDs are - stored in the array GROUPS; the return value from the function is - the number of group IDs actually stored. If COUNT is smaller than - the total number of supplementary group IDs, then `getgroups' - returns a value of `-1' and `errno' is set to `EINVAL'. - - If COUNT is zero, then `getgroups' just returns the total number - of supplementary group IDs.

A privileged process (effective user ID zero) can change its - effective user ID to any legal value. An unprivileged process - with a file user ID can change its effective user ID to its real - user ID or to its file user ID. Otherwise, a process may not - change its effective user ID at all. - - The `seteuid' function returns a value of `0' to indicate - successful completion, and a value of `-1' to indicate an error. - The following `errno' error conditions are defined for this - function: - - `EINVAL' - The value of the NEWUID argument is invalid. - - `EPERM' - The process may not change to the specified ID. - - Older systems (those without the `_POSIX_SAVED_IDS' feature) do not - have this function. - - - Function: int setuid (uid_t NEWUID) - If the calling process is privileged, this function sets both the - real and effective user ID of the process to NEWUID. It also - deletes the file user ID of the process, if any. NEWUID may be any - legal value. (Once this has been done, there is no way to recover - the old effective user ID.) - - If the process is not privileged, and the system supports the - `_POSIX_SAVED_IDS' feature, then this function behaves like - `seteuid'. - - The return values and error conditions are the same as for - `seteuid'. - - - Function: int setreuid (uid_t RUID, uid_t EUID) - This function sets the real user ID of the process to RUID and the - effective user ID to EUID. If RUID is `-1', it means not to - change the real user ID; likewise if EUID is `-1', it means not to - change the effective user ID. - - The `setreuid' function exists for compatibility with 4.3 BSD Unix, - which does not support file IDs. You can use this function to - swap the effective and real user IDs of the process. (Privileged - processes are not limited to this particular usage.)

Just as with `seteuid', if the process is privileged it may - change its effective group ID to any value; if it isn't, but it - has a file group ID, then it may change to its real group ID or - file group ID; otherwise it may not change its effective group ID. - - Note that a process is only privileged if its effective _user_ ID - is zero.

It - also deletes the file group ID, if any. - - If the process is not privileged, then `setgid' behaves like - `setegid'. - - The return values and error conditions for `setgid' are the same - as those for `seteuid'. - - - Function: int setregid (gid_t RGID, gid_t EGID) - This function sets the real group ID of the process to RGID and - the effective group ID to EGID. If RGID is `-1', it means not to - change the real group ID; likewise if EGID is `-1', it means not - to change the effective group ID. - - The `setregid' function is provided for compatibility with 4.3 BSD - Unix, which does not support file IDs. You can use this function - to swap the effective and real group IDs of the process. - (Privileged processes are not limited to this usage.) If file IDs - are supported, you should use that feature instead of using this - function. *Note Enable/Disable Setuid::. - - The return values and error conditions for `setregid' are the same - as those for `setreuid'. - - `setuid' and `setgid' behave differently depending on whether the -effective user ID at the time is zero. If it is not zero, they behave -like `seteuid' and `setegid'. If it is, they change both effective and -real IDs and delete the file ID. To avoid confusion, we recommend you -always use `seteuid' and `setegid' except when you know the effective -user ID is zero and your intent is to change the persona permanently. -This case is rare--most of the programs that need it, such as `login' -and `su', have already been written. - - Note that if your program is setuid to some user other than `root', -there is no way to drop privileges permanently. - - The system also lets privileged processes change their supplementary -group IDs. To use `setgroups' or `initgroups', your programs should -include the header file `grp.h'. - - - Function: int setgroups (size_t COUNT, gid_t *GROUPS) - This function sets the process's supplementary group IDs. It can - only be called from privileged processes. The COUNT argument - specifies the number of group IDs in the array GROUPS. - - This function returns `0' if successful and `-1' on error. The - following `errno' error conditions are defined for this function: - - `EPERM' - The calling process is not privileged. - - - Function: int initgroups (const char *USER, gid_t GROUP) - The `initgroups' function sets the process's supplementary group - IDs to be the normal default for the user name USER.

It then calls `setgroups' with the list it - has constructed. - - The return values and error conditions are the same as for - `setgroups'. - - If you are interested in the groups a particular user belongs to, -but do not want to change the process's supplementary group IDs, you -can use `getgrouplist'. To use `getgrouplist', your programs should -include the header file `grp.h'. - - - Function: int getgrouplist (const char *USER, gid_t GROUP, gid_t - *GROUPS, int *NGROUPS) - The `getgrouplist' function scans the group database for all the - groups USER belongs to. Up to *NGROUPS group IDs corresponding to - these groups are stored in the array GROUPS; the return value from - the function is the number of group IDs actually stored. If - *NGROUPS is smaller than the total number of groups found, then - `getgrouplist' returns a value of `-1' and stores the actual - number of groups in *NGROUPS. The group GROUP is automatically - included in the list of groups returned by `getgrouplist'. - - Here's how to use `getgrouplist' to read all supplementary groups - for USER: - - gid_t * - supplementary_groups (char *user) - { - int ngroups = 16; - gid_t *groups - = (gid_t *) xmalloc (ngroups * sizeof (gid_t)); - struct passwd *pw = getpwnam (user); - - if (pw == NULL) - return NULL; - - if (getgrouplist (pw->pw_name, pw->pw_gid, groups, &ngroups) < 0) - { - groups = xrealloc (ngroups * sizeof (gid_t)); - getgrouplist (pw->pw_name, pw->pw_gid, groups, &ngroups); - } - return groups; - } - - -File: libc.info, Node: Enable/Disable Setuid, Next: Setuid Program Example, Prev: Setting Groups, Up: Users and Groups - -Enabling and Disabling Setuid Access -==================================== - - A typical setuid program does not need its special access all of the -time. It's a good idea to turn off this access when it isn't needed, -so it can't possibly give unintended access. - - If the system supports the `_POSIX_SAVED_IDS' feature, you can -accomplish this with `seteuid'. When the game program starts, its real -user ID is `jdoe', its effective user ID is `games', and its saved user -ID is also `games'. The program should record both user ID values once -at the beginning, like this: - - user_user_id = getuid (); - game_user_id = geteuid (); - - Then it can turn off game file access with - - seteuid (user_user_id); - -and turn it on with - - seteuid (game_user_id); - -Throughout this process, the real user ID remains `jdoe' and the file -user ID remains `games', so the program can always set its effective -user ID to either one. - - On other systems that don't support file user IDs, you can turn -setuid access on and off by using `setreuid' to swap the real and -effective user IDs of the process, as follows: - - setreuid (geteuid (), getuid ()); - -This special case is always allowed--it cannot fail. - - Why does this have the effect of toggling the setuid access? -Suppose a game program has just started, and its real user ID is `jdoe' -while its effective user ID is `games'. In this state, the game can -write the scores file. If it swaps the two uids, the real becomes -`games' and the effective becomes `jdoe'; now the program has only -`jdoe' access. Another swap brings `games' back to the effective user -ID and restores access to the scores file. - - In order to handle both kinds of systems, test for the saved user ID -feature with a preprocessor conditional, like this: - - #ifdef _POSIX_SAVED_IDS - seteuid (user_user_id); - #else - setreuid (geteuid (), getuid ()); - #endif - - -File: libc.info, Node: Setuid Program Example, Next: Tips for Setuid, Prev: Enable/Disable Setuid, Up: Users and Groups - -Setuid Program Example -====================== - - Here's an example showing how to set up a program that changes its -effective user ID. - - This is part of a game program called `caber-toss' that manipulates -a file `scores' that should be writable only by the game program -itself.

If the resource is - specific to your particular program, it's better to define a new, - nonprivileged user ID or group ID just to manage that resource. - It's better if you can write your program to use a special group - than a special user. - - * Be cautious about using the `exec' functions in combination with - changing the effective user ID. Don't let users of your program - execute arbitrary programs under a changed user ID. Executing a - shell is especially bad news. Less obviously, the `execlp' and - `execvp' functions are a potential risk (since the program they - execute depends on the user's `PATH' environment variable). - - If you must `exec' another program under a changed ID, specify an - absolute file name (*note File Name Resolution::) for the - executable, and make sure that the protections on that executable - and _all_ containing directories are such that ordinary users - cannot replace it with some other program. - - You should also check the arguments passed to the program to make - sure they do not have unexpected effects. Likewise, you should - examine the environment variables. Decide which arguments and - variables are safe, and reject all others. - - You should never use `system' in a privileged program, because it - invokes a shell. - - * Only use the user ID controlling the resource in the part of the - program that actually uses that resource. When you're finished - with it, restore the effective user ID back to the actual user's - user ID. *Note Enable/Disable Setuid::. - - * If the `setuid' part of your program needs to access other files - besides the controlled resource, it should verify that the real - user would ordinarily have permission to access those files. You - can use the `access' function (*note Access Permission::) to check - this; it uses the real user and group IDs, rather than the - effective IDs. - - -File: libc.info, Node: Who Logged In, Next: User Accounting Database, Prev: Tips for Setuid, Up: Users and Groups - -Identifying Who Logged In -========================= - - You can use the functions listed in this section to determine the -login name of the user who is running a process, and the name of the -user who logged in the current session. See also the function `getuid' -and friends (*note Reading Persona::). How this information is -collected by the system and how to control/add/remove information from -the background storage is described in *Note User Accounting Database::. - - The `getlogin' function is declared in `unistd.h', while `cuserid' -and `L_cuserid' are declared in `stdio.h'. - - - Function: char * getlogin (void) - The `getlogin' function returns a pointer to a string containing - the name of the user logged in on the controlling terminal of the - process, or a null pointer if this information cannot be - determined. The string is statically allocated and might be - overwritten on subsequent calls to this function or to `cuserid'. - - - Function: char * cuserid (char *STRING) - The `cuserid' function returns a pointer to a string containing a - user name associated with the effective ID of the process. If - STRING is not a null pointer, it should be an array that can hold - at least `L_cuserid' characters; the string is returned in this - array. Otherwise, a pointer to a string in a static area is - returned. This string is statically allocated and might be - overwritten on subsequent calls to this function or to `getlogin'. - - The use of this function is deprecated since it is marked to be - withdrawn in XPG4.2 and has already been removed from newer - revisions of POSIX.1. - - - Macro: int L_cuserid - An integer constant that indicates how long an array you might - need to store a user name. - - These functions let your program identify positively the user who is -running or the user who logged in this session. (These can differ when -setuid programs are involved; see *Note Process Persona::.) The user -cannot do anything to fool these functions. - - For most purposes, it is more useful to use the environment variable -`LOGNAME' to find out who the user is. This is more flexible precisely -because the user can set `LOGNAME' arbitrarily. *Note Standard -Environment::. - - -File: libc.info, Node: User Accounting Database, Next: User Database, Prev: Who Logged In, Up: Users and Groups - -The User Accounting Database -============================ - - Most Unix-like operating systems keep track of logged in users by -maintaining a user accounting database. This user accounting database -stores for each terminal, who has logged on, at what time, the process -ID of the user's login shell, etc., etc., but also stores information -about the run level of the system, the time of the last system reboot, -and possibly more. - - The user accounting database typically lives in `/etc/utmp', -`/var/adm/utmp' or `/var/run/utmp'. However, these files should -*never* be accessed directly. For reading information from and writing -information to the user accounting database, the functions described in -this section should be used. - -* Menu: - -* Manipulating the Database:: Scanning and modifying the user - accounting database. -* XPG Functions:: A standardized way for doing the same thing. -* Logging In and Out:: Functions from BSD that modify the user - accounting database. - - -File: libc.info, Node: Manipulating the Database, Next: XPG Functions, Up: User Accounting Database - -Manipulating the User Accounting Database ------------------------------------------ - - These functions and the corresponding data structures are declared in -the header file `utmp.h'. - - - Data Type: struct exit_status - The `exit_status' data structure is used to hold information about - the exit status of processes marked as `DEAD_PROCESS' in the user - accounting database. - - `short int e_termination' - The exit status of the process. - - `short int e_exit' - The exit status of the process. - - - Data Type: struct utmp - The `utmp' data structure is used to hold information about entries - in the user accounting database. On the GNU system it has the - following members: - - `short int ut_type' - Specifies the type of login; one of `EMPTY', `RUN_LVL', - `BOOT_TIME', `OLD_TIME', `NEW_TIME', `INIT_PROCESS', - `LOGIN_PROCESS', `USER_PROCESS', `DEAD_PROCESS' or - `ACCOUNTING'. - - `pid_t ut_pid' - The process ID number of the login process. - - `char ut_line[]' - The device name of the tty (without `/dev/'). - - `char ut_id[]' - The inittab ID of the process. - - `char ut_user[]' - The user's login name. - - `char ut_host[]' - The name of the host from which the user logged in. - - `struct exit_status ut_exit' - The exit status of a process marked as `DEAD_PROCESS'. - - `long ut_session' - The Session ID, used for windowing. - - `struct timeval ut_tv' - Time the entry was made. For entries of type `OLD_TIME' this - is the time when the system clock changed, and for entries of - type `NEW_TIME' this is the time the system clock was set to. - - `int32_t ut_addr_v6[4]' - The Internet address of a remote host. - - The `ut_type', `ut_pid', `ut_id', `ut_tv', and `ut_host' fields are -not available on all systems. Portable applications therefore should -be prepared for these situations. To help doing this the `utmp.h' -header provides macros `_HAVE_UT_TYPE', `_HAVE_UT_PID', `_HAVE_UT_ID', -`_HAVE_UT_TV', and `_HAVE_UT_HOST' if the respective field is -available. The programmer can handle the situations by using `#ifdef' -in the program code. - - The following macros are defined for use as values for the `ut_type' -member of the `utmp' structure. The values are integer constants. - -`EMPTY' - This macro is used to indicate that the entry contains no valid - user accounting information. - -`RUN_LVL' - This macro is used to identify the systems runlevel. - -`BOOT_TIME' - This macro is used to identify the time of system boot. - -`OLD_TIME' - This macro is used to identify the time when the system clock - changed. - -`NEW_TIME' - This macro is used to identify the time after the system changed. - -`INIT_PROCESS' - This macro is used to identify a process spawned by the init - process. - -`LOGIN_PROCESS' - This macro is used to identify the session leader of a logged in - user. - -`USER_PROCESS' - This macro is used to identify a user process. - -`DEAD_PROCESS' - This macro is used to identify a terminated process. - -`ACCOUNTING' - ??? - - The size of the `ut_line', `ut_id', `ut_user' and `ut_host' arrays -can be found using the `sizeof' operator. - - Many older systems have, instead of an `ut_tv' member, an `ut_time' -member, usually of type `time_t', for representing the time associated -with the entry. Therefore, for backwards compatibility only, `utmp.h' -defines `ut_time' as an alias for `ut_tv.tv_sec'. - - - Function: void setutent (void) - This function opens the user accounting database to begin scanning - it. You can then call `getutent', `getutid' or `getutline' to - read entries and `pututline' to write entries. - - If the database is already open, it resets the input to the - beginning of the database. - - - Function: struct utmp * getutent (void) - The `getutent' function reads the next entry from the user - accounting database. It returns a pointer to the entry, which is - statically allocated and may be overwritten by subsequent calls to - `getutent'. You must copy the contents of the structure if you - wish to save the information or you can use the `getutent_r' - function which stores the data in a user-provided buffer. - - A null pointer is returned in case no further entry is available. - - - Function: void endutent (void) - This function closes the user accounting database. - - - Function: struct utmp * getutid (const struct utmp *ID) - This function searches forward from the current point in the - database for an entry that matches ID. If the `ut_type' member of - the ID structure is one of `RUN_LVL', `BOOT_TIME', `OLD_TIME' or - `NEW_TIME' the entries match if the `ut_type' members are - identical. If the `ut_type' member of the ID structure is - `INIT_PROCESS', `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS', - the entries match if the `ut_type' member of the entry read from - the database is one of these four, and the `ut_id' members match. - However if the `ut_id' member of either the ID structure or the - entry read from the database is empty it checks if the `ut_line' - members match instead. If a matching entry is found, `getutid' - returns a pointer to the entry, which is statically allocated, and - may be overwritten by a subsequent call to `getutent', `getutid' - or `getutline'. You must copy the contents of the structure if - you wish to save the information. - - A null pointer is returned in case the end of the database is - reached without a match. - - The `getutid' function may cache the last read entry. Therefore, - if you are using `getutid' to search for multiple occurrences, it - is necessary to zero out the static data after each call. - Otherwise `getutid' could just return a pointer to the same entry - over and over again. - - - Function: struct utmp * getutline (const struct utmp *LINE) - This function searches forward from the current point in the - database until it finds an entry whose `ut_type' value is - `LOGIN_PROCESS' or `USER_PROCESS', and whose `ut_line' member - matches the `ut_line' member of the LINE structure. If it finds - such an entry, it returns a pointer to the entry which is - statically allocated, and may be overwritten by a subsequent call - to `getutent', `getutid' or `getutline'. You must copy the - contents of the structure if you wish to save the information. - - A null pointer is returned in case the end of the database is - reached without a match. - - The `getutline' function may cache the last read entry. Therefore - if you are using `getutline' to search for multiple occurrences, it - is necessary to zero out the static data after each call. - Otherwise `getutline' could just return a pointer to the same - entry over and over again. - - - Function: struct utmp * pututline (const struct utmp *UTMP) - The `pututline' function inserts the entry `*UTMP' at the - appropriate place in the user accounting database. If it finds - that it is not already at the correct place in the database, it - uses `getutid' to search for the position to insert the entry, - however this will not modify the static structure returned by - `getutent', `getutid' and `getutline'. If this search fails, the - entry is appended to the database. - - The `pututline' function returns a pointer to a copy of the entry - inserted in the user accounting database, or a null pointer if the - entry could not be added. The following `errno' error conditions - are defined for this function: - - `EPERM' - The process does not have the appropriate privileges; you - cannot modify the user accounting database. - - All the `get*' functions mentioned before store the information they -return in a static buffer. This can be a problem in multi-threaded -programs since the data returned for the request is overwritten by the -return value data in another thread. Therefore the GNU C Library -provides as extensions three more functions which return the data in a -user-provided buffer. - - - Function: int getutent_r (struct utmp *BUFFER, struct utmp **RESULT) - The `getutent_r' is equivalent to the `getutent' function. It - returns the next entry from the database. But instead of storing - the information in a static buffer it stores it in the buffer - pointed to by the parameter BUFFER. - - If the call was successful, the function returns `0' and the - pointer variable pointed to by the parameter RESULT contains a - pointer to the buffer which contains the result (this is most - probably the same value as BUFFER). If something went wrong - during the execution of `getutent_r' the function returns `-1'. - - This function is a GNU extension. - - - Function: int getutid_r (const struct utmp *ID, struct utmp *BUFFER, - struct utmp **RESULT) - This function retrieves just like `getutid' the next entry matching - the information stored in ID. But the result is stored in the - buffer pointed to by the parameter BUFFER. - - If successful the function returns `0' and the pointer variable - pointed to by the parameter RESULT contains a pointer to the - buffer with the result (probably the same as RESULT. If not - successful the function return `-1'. - - This function is a GNU extension. - - - Function: int getutline_r (const struct utmp *LINE, struct utmp - *BUFFER, struct utmp **RESULT) - This function retrieves just like `getutline' the next entry - matching the information stored in LINE. But the result is stored - in the buffer pointed to by the parameter BUFFER. - - If successful the function returns `0' and the pointer variable - pointed to by the parameter RESULT contains a pointer to the - buffer with the result (probably the same as RESULT. If not - successful the function return `-1'. - - This function is a GNU extension. - - In addition to the user accounting database, most systems keep a -number of similar databases. For example most systems keep a log file -with all previous logins (usually in `/etc/wtmp' or `/var/log/wtmp'). - - For specifying which database to examine, the following function -should be used. - - - Function: int utmpname (const char *FILE) - The `utmpname' function changes the name of the database to be - examined to FILE, and closes any previously opened database. By - default `getutent', `getutid', `getutline' and `pututline' read - from and write to the user accounting database. - - The following macros are defined for use as the FILE argument: - - - Macro: char * _PATH_UTMP - This macro is used to specify the user accounting database. - - - Macro: char * _PATH_WTMP - This macro is used to specify the user accounting log file. - - The `utmpname' function returns a value of `0' if the new name was - successfully stored, and a value of `-1' to indicate an error. - Note that `utmpname' does not try to open the database, and that - therefore the return value does not say anything about whether the - database can be successfully opened. - - Specially for maintaining log-like databases the GNU C Library -provides the following function: - - - Function: void updwtmp (const char *WTMP_FILE, const struct utmp - *UTMP) - The `updwtmp' function appends the entry *UTMP to the database - specified by WTMP_FILE. For possible values for the WTMP_FILE - argument see the `utmpname' function. - - *Portability Note:* Although many operating systems provide a subset -of these functions, they are not standardized. There are often subtle -differences in the return types, and there are considerable differences -between the various definitions of `struct utmp'. When programming for -the GNU system, it is probably best to stick with the functions -described in this section. If however, you want your program to be -portable, consider using the XPG functions described in *Note XPG -Functions::, or take a look at the BSD compatible functions in *Note -Logging In and Out::. - - -File: libc.info, Node: XPG Functions, Next: Logging In and Out, Prev: Manipulating the Database, Up: User Accounting Database - -XPG User Accounting Database Functions --------------------------------------- - - These functions, described in the X/Open Portability Guide, are -declared in the header file `utmpx.h'. - - - Data Type: struct utmpx - The `utmpx' data structure contains at least the following members: - - `short int ut_type' - Specifies the type of login; one of `EMPTY', `RUN_LVL', - `BOOT_TIME', `OLD_TIME', `NEW_TIME', `INIT_PROCESS', - `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS'. - - `pid_t ut_pid' - The process ID number of the login process. - - `char ut_line[]' - The device name of the tty (without `/dev/'). - - `char ut_id[]' - The inittab ID of the process. - - `char ut_user[]' - The user's login name. - - `struct timeval ut_tv' - Time the entry was made.

E.g., it is useful to associate a certain -group of users with a certain machine. On the other hand grouping of -host names is not supported so far. - - In Sun Microsystems SunOS appeared a new kind of database, the -netgroup database. It allows grouping hosts, users, and domains -freely, giving them individual names. To be more concrete, a netgroup -is a list of triples consisting of a host name, a user name, and a -domain name where any of the entries can be a wildcard entry matching -all inputs. A last possibility is that names of other netgroups can -also be given in the list specifying a netgroup. So one can construct -arbitrary hierarchies without loops. - - Sun's implementation allows netgroups only for the `nis' or -`nisplus' service, *note Services in the NSS configuration::. The -implementation in the GNU C library has no such restriction. An entry -in either of the input services must have the following form: - - GROUPNAME ( GROUPNAME | `('HOSTNAME`,'USERNAME`,'`domainname'`)' )+ - - Any of the fields in the triple can be empty which means anything -matches. While describing the functions we will see that the opposite -case is useful as well. I.e., there may be entries which will not -match any input. For entries like this, a name consisting of the single -character `-' shall be used. - - -File: libc.info, Node: Lookup Netgroup, Next: Netgroup Membership, Prev: Netgroup Data, Up: Netgroup Database - -Looking up one Netgroup ------------------------ - - The lookup functions for netgroups are a bit different to all other -system database handling functions. Since a single netgroup can contain -many entries a two-step process is needed. First a single netgroup is -selected and then one can iterate over all entries in this netgroup. -These functions are declared in `netdb.h'. - - - Function: int setnetgrent (const char *NETGROUP) - A call to this function initializes the internal state of the - library to allow following calls of the `getnetgrent' to iterate - over all entries in the netgroup with name NETGROUP. - - When the call is successful (i.e., when a netgroup with this name - exists) the return value is `1'. When the return value is `0' no - netgroup of this name is known or some other error occurred. - - It is important to remember that there is only one single state for -iterating the netgroups. Even if the programmer uses the -`getnetgrent_r' function the result is not really reentrant since -always only one single netgroup at a time can be processed. If the -program needs to process more than one netgroup simultaneously she must -protect this by using external locking. This problem was introduced in -the original netgroups implementation in SunOS and since we must stay -compatible it is not possible to change this. - - Some other functions also use the netgroups state. Currently these -are the `innetgr' function and parts of the implementation of the -`compat' service part of the NSS implementation. - - - Function: int getnetgrent (char **HOSTP, char **USERP, char - **DOMAINP) - This function returns the next unprocessed entry of the currently - selected netgroup. The string pointers, in which addresses are - passed in the arguments HOSTP, USERP, and DOMAINP, will contain - after a successful call pointers to appropriate strings. If the - string in the next entry is empty the pointer has the value `NULL'. - The returned string pointers are only valid if none of the netgroup - related functions are called. - - The return value is `1' if the next entry was successfully read. A - value of `0' means no further entries exist or internal errors - occurred. - - - Function: int getnetgrent_r (char **HOSTP, char **USERP, char - **DOMAINP, char *BUFFER, int BUFLEN) - This function is similar to `getnetgrent' with only one exception: - the strings the three string pointers HOSTP, USERP, and DOMAINP - point to, are placed in the buffer of BUFLEN bytes starting at - BUFFER. This means the returned values are valid even after other - netgroup related functions are called. - - The return value is `1' if the next entry was successfully read and - the buffer contains enough room to place the strings in it. `0' is - returned in case no more entries are found, the buffer is too - small, or internal errors occurred. - - This function is a GNU extension. The original implementation in - the SunOS libc does not provide this function. - - - Function: void endnetgrent (void) - This function frees all buffers which were allocated to process - the last selected netgroup.

First, let's review the various ways computer -systems are named, which is a little complicated because of the history -of the development of the Internet. - - Every Unix system (also known as a host) has a host name, whether -it's connected to a network or not. In its simplest form, as used -before computer networks were an issue, it's just a word like `chicken'. - - But any system attached to the Internet or any network like it -conforms to a more rigorous naming convention as part of the Domain -Name System (DNS). In DNS, every host name is composed of two parts: - - 1. hostname - - 2. domain name - - You will note that "hostname" looks a lot like "host name", but is -not the same thing, and that people often incorrectly refer to entire -host names as "domain names." - - In DNS, the full host name is properly called the FQDN (Fully -Qualified Domain Name) and consists of the hostname, then a period, -then the domain name. The domain name itself usually has multiple -components separated by periods. So for example, a system's hostname -may be `chicken' and its domain name might be `ai.mit.edu', so its FQDN -(which is its host name) is `chicken.ai.mit.edu'. - - Adding to the confusion, though, is that DNS is not the only name -space in which a computer needs to be known. Another name space is the -NIS (aka YP) name space. For NIS purposes, there is another domain -name, which is called the NIS domain name or the YP domain name. It -need not have anything to do with the DNS domain name. - - Confusing things even more is the fact that in DNS, it is possible -for multiple FQDNs to refer to the same system. However, there is -always exactly one of them that is the true host name, and it is called -the canonical FQDN. - - In some contexts, the host name is called a "node name." - - For more information on DNS host naming, *Note Host Names::. - - Prototypes for these functions appear in `unistd.h'. - - The programs `hostname', `hostid', and `domainname' work by calling -these functions. - - - Function: int gethostname (char *NAME, size_t SIZE) - This function returns the host name of the system on which it is - called, in the array NAME. The SIZE argument specifies the size of - this array, in bytes. Note that this is _not_ the DNS hostname. - If the system participates in DNS, this is the FQDN (see above). - - The return value is `0' on success and `-1' on failure. In the - GNU C library, `gethostname' fails if SIZE is not large enough; - then you can try again with a larger array. The following `errno' - error condition is defined for this function: - - `ENAMETOOLONG' - The SIZE argument is less than the size of the host name plus - one. - - On some systems, there is a symbol for the maximum possible host - name length: `MAXHOSTNAMELEN'. It is defined in `sys/param.h'. - But you can't count on this to exist, so it is cleaner to handle - failure and try again. - - `gethostname' stores the beginning of the host name in NAME even - if the host name won't entirely fit. For some purposes, a - truncated host name is good enough. If it is, you can ignore the - error code. - - - Function: int sethostname (const char *NAME, size_t LENGTH) - The `sethostname' function sets the host name of the system that - calls it to NAME, a string with length LENGTH. Only privileged - processes are permitted to do this. - - Usually `sethostname' gets called just once, at system boot time. - Often, the program that calls it sets it to the value it finds in - the file `/etc/hostname'. - - Be sure to set the host name to the full host name, not just the - DNS hostname (see above). - - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is defined for this function: - - `EPERM' - This process cannot set the host name because it is not - privileged. - - - Function: int getdomainnname (char *NAME, size_t LENGTH) - `getdomainname' returns the NIS (aka YP) domain name of the system - on which it is called. Note that this is not the more popular DNS - domain name. Get that with `gethostname'. - - The specifics of this function are analogous to `gethostname', - above. - - - - Function: int setdomainname (const char *NAME, size_t LENGTH) - `getdomainname' sets the NIS (aka YP) domain name of the system on - which it is called. Note that this is not the more popular DNS - domain name. Set that with `sethostname'. - - The specifics of this function are analogous to `sethostname', - above. - - - - Function: long int gethostid (void) - This function returns the "host ID" of the machine the program is - running on. By convention, this is usually the primary Internet - IP address of that machine, converted to a `long int'. However, - on some systems it is a meaningless but unique number which is - hard-coded for each machine. - - This is not widely used. It arose in BSD 4.2, but was dropped in - BSD 4.4. It is not required by POSIX. - - The proper way to query the IP address is to use `gethostbyname' - on the results of `gethostname'. For more information on IP - addresses, *Note Host Addresses::. - - - Function: int sethostid (long int ID) - The `sethostid' function sets the "host ID" of the host machine to - ID. Only privileged processes are permitted to do this. Usually - it happens just once, at system boot time. - - The proper way to establish the primary IP address of a system is - to configure the IP address resolver to associate that IP address - with the system's host name as returned by `gethostname'. For - example, put a record for the system in `/etc/hosts'. - - See `gethostid' above for more information on host ids. - - The return value is `0' on success and `-1' on failure. The - following `errno' error conditions are defined for this function: - - `EPERM' - This process cannot set the host name because it is not - privileged. - - `ENOSYS' - The operating system does not support setting the host ID. - On some systems, the host ID is a meaningless but unique - number hard-coded for each machine. - - -File: libc.info, Node: Platform Type, Next: Filesystem Handling, Prev: Host Identification, Up: System Management - -Platform Type Identification -============================ - - You can use the `uname' function to find out some information about -the type of computer your program is running on. This function and the -associated data type are declared in the header file `sys/utsname.h'. - - As a bonus, `uname' also gives some information identifying the -particular system your program is running on. This is the same -information which you can get with functions targetted to this purpose -described in *Note Host Identification::. - - - Data Type: struct utsname - The `utsname' structure is used to hold information returned by - the `uname' function.

On systems without such a - mechanism, the GNU C library fills in this field based on the - configuration name that was specified when building and - installing the library. - - GNU uses a three-part name to describe a system - configuration; the three parts are CPU, MANUFACTURER and - SYSTEM-TYPE, and they are separated with dashes. Any - possible combination of three names is potentially - meaningful, but most such combinations are meaningless in - practice and even the meaningful ones are not necessarily - supported by any particular GNU program. - - Since the value in `machine' is supposed to describe just the - hardware, it consists of the first two parts of the - configuration name: `CPU-MANUFACTURER'. For example, it - might be one of these: - - `"sparc-sun"', `"i386-ANYTHING"', `"m68k-hp"', - `"m68k-sony"', `"m68k-sun"', `"mips-dec"' - - `char nodename[]' - This is the host name of this particular computer. In the - GNU C library, the value is the same as that returned by - `gethostname'; see *Note Host Identification::. - - gethostname() is implemented with a call to uname(). - - `char domainname[]' - This is the NIS or YP domain name. It is the same value - returned by `getdomainname'; see *Note Host Identification::. - This element is a relatively recent invention and use of it - is not as portable as use of the rest of the structure. - - - - Function: int uname (struct utsname *INFO) - The `uname' function fills in the structure pointed to by INFO - with information about the operating system and host machine. A - non-negative value indicates that the data was successfully stored. - - `-1' as the value indicates an error.

Because of Unix's concept of _Everything -is a file_, mounting of filesystems is central to doing almost -anything. This section explains how to find out what filesystems are -currently mounted and what filesystems are available for mounting, and -how to change what is mounted. - - The classic filesystem is the contents of a disk drive. The concept -is considerably more abstract, though, and lots of things other than -disk drives can be mounted. - - Some block devices don't correspond to traditional devices like disk -drives. For example, a loop device is a block device whose driver uses -a regular file in another filesystem as its medium. So if that regular -file contains appropriate data for a filesystem, you can by mounting the -loop device essentially mount a regular file. - - Some filesystems aren't based on a device of any kind. The "proc" -filesystem, for example, contains files whose data is made up by the -filesystem driver on the fly whenever you ask for it. And when you -write to it, the data you write causes changes in the system.

The GNU libc -provides some functions to retrieve this information portably. - - Traditionally Unix systems have a file named `/etc/fstab' which -describes all possibly mounted filesystems. The `mount' program uses -this file to mount at startup time of the system all the necessary -filesystems. The information about all the filesystems actually -mounted is normally kept in a file named either `/var/run/mtab' or -`/etc/mtab'. Both files share the same syntax and it is crucial that -this syntax is followed all the time. Therefore it is best to never -directly write the files. The functions described in this section can -do this and they also provide the functionality to convert the external -textual representation to the internal representation. - - Note that the `fstab' and `mtab' files are maintained on a system by -_convention_. It is possible for the files not to exist or not to be -consistent with what is really mounted or available to mount, if the -system's administration policy allows it. But programs that mount and -unmount filesystems typically maintain and use these files as described -herein. - - The filenames given above should never be used directly. The -portable way to handle these file is to use the macro `_PATH_FSTAB', -defined in `fstab.h', or `_PATH_MNTTAB', defined in `mntent.h' and -`paths.h', for `fstab'; and the macro `_PATH_MOUNTED', also defined in -`mntent.h' and `paths.h', for `mtab'. There are also two alternate -macro names `FSTAB', `MNTTAB', and `MOUNTED' defined but these names -are deprecated and kept only for backward compatibility.

For "NFS" it would be a hostname and - directory name combination. - - Even though the element is not declared `const' it shouldn't - be modified. The missing `const' has historic reasons, since - this function predates ISO C. The same is true for the other - string elements of this structure. - - `char *fs_file' - This describes the mount point on the local system. I.e., - accessing any file in this filesystem has implicitly or - explicitly this string as a prefix. - - `char *fs_vfstype' - This is the type of the filesystem. Depending on what the - underlying kernel understands it can be any string. - - `char *fs_mntops' - This is a string containing options passed to the kernel with - the `mount' call. Again, this can be almost anything. There - can be more than one option, separated from the others by a - comma. Each option consists of a name and an optional value - part, introduced by an `=' character. - - If the value of this element must be processed it should - ideally be done using the `getsubopt' function; see *Note - Suboptions::. - - `const char *fs_type' - This name is poorly chosen. This element points to a string - (possibly in the `fs_mntops' string) which describes the - modes with which the filesystem is mounted. `fstab' defines - five macros to describe the possible values: - - `FSTAB_RW' - The filesystems gets mounted with read and write enabled. - - `FSTAB_RQ' - The filesystems gets mounted with read and write - enabled. Write access is restricted by quotas. - - `FSTAB_RO' - The filesystem gets mounted read-only. - - `FSTAB_SW' - This is not a real filesystem, it is a swap device. - - `FSTAB_XX' - This entry from the `fstab' file is totally ignored. - - Testing for equality with these value must happen using - `strcmp' since these are all strings. Comparing the pointer - will probably always fail. - - `int fs_freq' - This element describes the dump frequency in days. - - `int fs_passno' - This element describes the pass number on parallel dumps. It - is closely related to the `dump' utility used on Unix systems. - - To read the entire content of the of the `fstab' file the GNU libc -contains a set of three functions which are designed in the usual way. - - - Function: int setfsent (void) - This function makes sure that the internal read pointer for the - `fstab' file is at the beginning of the file. This is done by - either opening the file or resetting the read pointer. - - Since the file handle is internal to the libc this function is not - thread-safe. - - This function returns a non-zero value if the operation was - successful and the `getfs*' functions can be used to read the - entries of the file. - - - Function: void endfsent (void) - This function makes sure that all resources acquired by a prior - call to `setfsent' (explicitly or implicitly by calling - `getfsent') are freed. - - - Function: struct fstab * getfsent (void) - This function returns the next entry of the `fstab' file. If this - is the first call to any of the functions handling `fstab' since - program start or the last call of `endfsent', the file will be - opened. - - The function returns a pointer to a variable of type `struct - fstab'. This variable is shared by all threads and therefore this - function is not thread-safe. If an error occurred `getfsent' - returns a `NULL' pointer. - - - Function: struct fstab * getfsspec (const char *NAME) - This function returns the next entry of the `fstab' file which has - a string equal to NAME pointed to by the `fs_spec' element. Since - there is normally exactly one entry for each special device it - makes no sense to call this function more than once for the same - argument. If this is the first call to any of the functions - handling `fstab' since program start or the last call of - `endfsent', the file will be opened. - - The function returns a pointer to a variable of type `struct - fstab'. This variable is shared by all threads and therefore this - function is not thread-safe. If an error occurred `getfsent' - returns a `NULL' pointer. - - - Function: struct fstab * getfsfile (const char *NAME) - This function returns the next entry of the `fstab' file which has - a string equal to NAME pointed to by the `fs_file' element. Since - there is normally exactly one entry for each mount point it makes - no sense to call this function more than once for the same - argument. If this is the first call to any of the functions - handling `fstab' since program start or the last call of - `endfsent', the file will be opened. - - The function returns a pointer to a variable of type `struct - fstab'.

It corresponds to the `fs_spec' element in `struct - fstab'. - - `char *mnt_dir' - This element points to a string describing the mount point of - the filesystem. It corresponds to the `fs_file' element in - `struct fstab'. - - `char *mnt_type' - `mnt_type' describes the filesystem type and is therefore - equivalent to `fs_vfstype' in `struct fstab'. `mntent.h' - defines a few symbolic names for some of the values this - string can have. But since the kernel can support arbitrary - filesystems it does not make much sense to give them symbolic - names. If one knows the symbol name one also knows the - filesystem name. Nevertheless here follows the list of the - symbols provided in `mntent.h'. - - `MNTTYPE_IGNORE' - This symbol expands to `"ignore"'. The value is - sometime used in `fstab' files to make sure entries are - not used without removing them. - - `MNTTYPE_NFS' - Expands to `"nfs"'. Using this macro sometimes could - make sense since it names the default NFS - implementation, in case both version 2 and 3 are - supported. - - `MNTTYPE_SWAP' - This symbol expands to `"swap"'. It names the special - `fstab' entry which names one of the possibly multiple - swap partitions. - - `char *mnt_opts' - The element contains a string describing the options used - while mounting the filesystem. As for the equivalent element - `fs_mntops' of `struct fstab' it is best to use the function - `getsubopt' (*note Suboptions::) to access the parts of this - string. - - The `mntent.h' file defines a number of macros with string - values which correspond to some of the options understood by - the kernel. There might be many more options which are - possible so it doesn't make much sense to rely on these - macros but to be consistent here is the list: - - `MNTOPT_DEFAULTS' - Expands to `"defaults"'. This option should be used - alone since it indicates all values for the customizable - values are chosen to be the default. - - `MNTOPT_RO' - Expands to `"ro"'. See the `FSTAB_RO' value, it means - the filesystem is mounted read-only. - - `MNTOPT_RW' - Expand to `"rw"'. See the `FSTAB_RW' value, it means the - filesystem is mounted with read and write permissions. - - `MNTOPT_SUID' - Expands to `"suid"'. This means that the SUID bit - (*note How Change Persona::) is respected when a program - from the filesystem is started. - - `MNTOPT_NOSUID' - Expands to `"nosuid"'. This is the opposite of - `MNTOPT_SUID', the SUID bit for all files from the - filesystem is ignored. - - `MNTOPT_NOAUTO' - Expands to `"noauto"'. At startup time the `mount' - program will ignore this entry if it is started with the - `-a' option to mount all filesystems mentioned in the - `fstab' file. - - As for the `FSTAB_*' entries introduced above it is important - to use `strcmp' to check for equality. - - `mnt_freq' - This elements corresponds to `fs_freq' and also specifies the - frequency in days in which dumps are made. - - `mnt_passno' - This element is equivalent to `fs_passno' with the same - meaning which is uninteresting for all programs beside `dump'. - - For accessing the `mtab' file there is again a set of three -functions to access all entries in a row. Unlike the functions to -handle `fstab' these functions do not access a fixed file and there is -even a thread safe variant of the get function. Beside this the GNU -libc contains functions to alter the file and test for specific options. - - - Function: FILE * setmntent (const char *FILE, const char *MODE) - The `setmntent' function prepares the file named FILE which must - be in the format of a `fstab' and `mtab' file for the upcoming - processing through the other functions of the family. The MODE - parameter can be chosen in the way the OPENTYPE parameter for - `fopen' (*note Opening Streams::) can be chosen. If the file is - opened for writing the file is also allowed to be empty. - - If the file was successfully opened `setmntent' returns a file - descriptor for future use. Otherwise the return value is `NULL' - and `errno' is set accordingly. - - - Function: int endmntent (FILE *STREAM) - This function takes for the STREAM parameter a file handle which - previously was returned from the `setmntent' call. `endmntent' - closes the stream and frees all resources. - - The return value is 1 unless an error occurred in which case it is - 0. - - - Function: struct mntent * getmntent (FILE *STREAM) - The `getmntent' function takes as the parameter a file handle - previously returned by successful call to `setmntent'. It returns - a pointer to a static variable of type `struct mntent' which is - filled with the information from the next entry from the file - currently read. - - The file format used prescribes the use of spaces or tab - characters to separate the fields. This makes it harder to use - name containing one of these characters (e.g., mount points using - spaces). Therefore these characters are encoded in the files and - the `getmntent' function takes care of the decoding while reading - the entries back in. `'\040'' is used to encode a space - character, `'\012'' to encode a tab character and `'\\'' to encode - a backslash. - - If there was an error or the end of the file is reached the return - value is `NULL'. - - This function is not thread-safe since all calls to this function - return a pointer to the same static variable. `getmntent_r' - should be used in situations where multiple threads access the - file. - - - Function: struct mntent * getmntent_r (FILE *STREAM, struct mentent - *RESULT, char *BUFFER, int BUFSIZE) - The `getmntent_r' function is the reentrant variant of - `getmntent'. It also returns the next entry from the file and - returns a pointer. The actual variable the values are stored in - is not static, though. Instead the function stores the values in - the variable pointed to by the RESULT parameter. Additional - information (e.g., the strings pointed to by the elements of the - result) are kept in the buffer of size BUFSIZE pointed to by - BUFFER. - - Escaped characters (space, tab, backslash) are converted back in - the same way as it happens for `getmentent'. - - The function returns a `NULL' pointer in error cases. Errors - could be: - * error while reading the file, - - * end of file reached, - - * BUFSIZE is too small for reading a complete new entry. - - - Function: int addmntent (FILE *STREAM, const struct mntent *MNT) - The `addmntent' function allows adding a new entry to the file - previously opened with `setmntent'. The new entries are always - appended. I.e., even if the position of the file descriptor is - not at the end of the file this function does not overwrite an - existing entry following the current position. - - The implication of this is that to remove an entry from a file one - has to create a new file while leaving out the entry to be removed - and after closing the file remove the old one and rename the new - file to the chosen name. - - This function takes care of spaces and tab characters in the names - to be written to the file. It converts them and the backslash - character into the format describe in the `getmntent' description - above. - - This function returns 0 in case the operation was successful. - Otherwise the return value is 1 and `errno' is set appropriately. - - - Function: char * hasmntopt (const struct mntent *MNT, const char - *OPT) - This function can be used to check whether the string pointed to - by the `mnt_opts' element of the variable pointed to by MNT - contains the option OPT. If this is true a pointer to the - beginning of the option in the `mnt_opts' element is returned. If - no such option exists the function returns `NULL'. - - This function is useful to test whether a specific option is - present but when all options have to be processed one is better - off with using the `getsubopt' function to iterate over all - options in the string. - - -File: libc.info, Node: Other Mount Information, Prev: mtab, Up: Mount Information - -Other (Non-libc) Sources of Mount Information -............................................. - - On a system with a Linux kernel and the `proc' filesystem, you can -get information on currently mounted filesystems from the file `mounts' -in the `proc' filesystem. Its format is similar to that of the `mtab' -file, but represents what is truly mounted without relying on -facilities outside the kernel to keep `mtab' up to date. - - -File: libc.info, Node: Mount-Unmount-Remount, Prev: Mount Information, Up: Filesystem Handling - -Mount, Unmount, Remount ------------------------ - - This section describes the functions for mounting, unmounting, and -remounting filesystems. - - Only the superuser can mount, unmount, or remount a filesystem. - - These functions do not access the `fstab' and `mtab' files. You -should maintain and use these separately. *Note Mount Information::. - - The symbols in this section are declared in `sys/mount.h'. - - - Function: int mount (const char *SPECIAL_FILE, const char *DIR, - const char *FSTYPE, unsigned long int OPTIONS, const void - *DATA) - `mount' mounts or remounts a filesystem. The two operations are - quite different and are merged rather unnaturally into this one - function. The `MS_REMOUNT' option, explained below, determines - whether `mount' mounts or remounts. - - For a mount, the filesystem on the block device represented by the - device special file named SPECIAL_FILE gets mounted over the mount - point DIR. This means that the directory DIR (along with any - files in it) is no longer visible; in its place (and still with - the name DIR) is the root directory of the filesystem on the - device. - - As an exception, if the filesystem type (see below) is one which - is not based on a device (e.g. "proc"), `mount' instantiates a - filesystem and mounts it over DIR and ignores SPECIAL_FILE. - - For a remount, DIR specifies the mount point where the filesystem - to be remounted is (and remains) mounted and SPECIAL_FILE is - ignored. Remounting a filesystem means changing the options that - control operations on the filesystem while it is mounted. It does - not mean unmounting and mounting again. - - For a mount, you must identify the type of the filesystem as - FSTYPE. This type tells the kernel how to access the filesystem - and can be thought of as the name of a filesystem driver. The - acceptable values are system dependent. On a system with a Linux - kernel and the `proc' filesystem, the list of possible values is - in the file `filesystems' in the `proc' filesystem (e.g. type `cat - /proc/filesystems' to see the list). With a Linux kernel, the - types of filesystems that `mount' can mount, and their type names, - depends on what filesystem drivers are configured into the kernel - or loaded as loadable kernel modules. An example of a common - value for FSTYPE is `ext2'. - - For a remount, `mount' ignores FSTYPE. - - OPTIONS specifies a variety of options that apply until the - filesystem is unmounted or remounted. The precise meaning of an - option depends on the filesystem and with some filesystems, an - option may have no effect at all. Furthermore, for some - filesystems, some of these options (but never `MS_RDONLY') can be - overridden for individual file accesses via `ioctl'. - - OPTIONS is a bit string with bit fields defined using the - following mask and masked value macros: - - `MS_MGC_MASK' - This multibit field contains a magic number. If it does not - have the value `MS_MGC_VAL', `mount' assumes all the - following bits are zero and the DATA argument is a null - string, regardless of their actual values. - - `MS_REMOUNT' - This bit on means to remount the filesystem. Off means to - mount it. - - `MS_RDONLY' - This bit on specifies that no writing to the filesystem shall - be allowed while it is mounted. This cannot be overridden by - `ioctl'. This option is available on nearly all filesystems. - - `S_IMMUTABLE' - This bit on specifies that no writing to the files in the - filesystem shall be allowed while it is mounted. This can be - overridden for a particular file access by a properly - privileged call to `ioctl'. This option is a relatively new - invention and is not available on many filesystems. - - `S_APPEND' - This bit on specifies that the only file writing that shall - be allowed while the filesystem is mounted is appending. - Some filesystems allow this to be overridden for a particular - process by a properly privileged call to `ioctl'. This is a - relatively new invention and is not available on many - filesystems. - - `MS_NOSUID' - This bit on specifies that Setuid and Setgid permissions on - files in the filesystem shall be ignored while it is mounted. - - `MS_NOEXEC' - This bit on specifies that no files in the filesystem shall - be executed while the filesystem is mounted. - - `MS_NODEV' - This bit on specifies that no device special files in the - filesystem shall be accessible while the filesystem is - mounted. - - `MS_SYNCHRONOUS' - This bit on specifies that all writes to the filesystem while - it is mounted shall be synchronous; i.e. data shall be synced - before each write completes rather than held in the buffer - cache. - - `MS_MANDLOCK' - This bit on specifies that mandatory locks on files shall be - permitted while the filesystem is mounted. - - `MS_NOATIME' - This bit on specifies that access times of files shall not be - updated when the files are accessed while the filesystem is - mounted. - - `MS_NODIRATIME' - This bit on specifies that access times of directories shall - not be updated when the directories are accessed while the - filesystem in mounted. - - Any bits not covered by the above masks should be set off; - otherwise, results are undefined. - - The meaning of DATA depends on the filesystem type and is - controlled entirely by the filesystem driver in the kernel. - - Example: - - #include - - mount("/dev/hdb", "/cdrom", MS_MGC_VAL | MS_RDONLY | MS_NOSUID, ""); - - mount("/dev/hda2", "/mnt", MS_MGC_VAL | MS_REMOUNT, ""); - - Appropriate arguments for `mount' are conventionally recorded in - the `fstab' table. *Note Mount Information::. - - The return value is zero if the mount or remount is successful. - Otherwise, it is `-1' and `errno' is set appropriately. The - values of `errno' are filesystem dependent, but here is a general - list: - - `EPERM' - The process is not superuser. - - `ENODEV' - The file system type FSTYPE is not known to the kernel. - - `ENOTBLK' - The file DEV is not a block device special file. - - `EBUSY' - * The device is already mounted. - - * The mount point is busy. (E.g. it is some process' - working directory or has a filesystem mounted on it - already). - - * The request is to remount read-only, but there are files - open for write. - - `EINVAL' - * A remount was attempted, but there is no filesystem - mounted over the specified mount point. - - * The supposed filesystem has an invalid superblock. - - - `EACCES' - * The filesystem is inherently read-only (possibly due to - a switch on the device) and the process attempted to - mount it read/write (by setting the `MS_RDONLY' bit off). - - * SPECIAL_FILE or DIR is not accessible due to file - permissions. - - * SPECIAL_FILE is not accessible because it is in a - filesystem that is mounted with the `MS_NODEV' option. - - - `EM_FILE' - The table of dummy devices is full. `mount' needs to create a - dummy device (aka "unnamed" device) if the filesystem being - mounted is not one that uses a device. - - - - Function: int umount2 (const char *FILE, int FLAGS) - `umount2' unmounts a filesystem. - - You can identify the filesystem to unmount either by the device - special file that contains the filesystem or by the mount point. - The effect is the same. Specify either as the string FILE. - - FLAGS contains the one-bit field identified by the following mask - macro: - - `MNT_FORCE' - This bit on means to force the unmounting even if the - filesystem is busy, by making it unbusy first. If the bit is - off and the filesystem is busy, `umount2' fails with `errno' - = `EBUSY'. Depending on the filesystem, this may override - all, some, or no busy conditions. - - All other bits in FLAGS should be set to zero; otherwise, the - result is undefined. - - Example: - - #include - - umount2("/mnt", MNT_FORCE); - - umount2("/dev/hdd1", 0); - - After the filesystem is unmounted, the directory that was the - mount point is visible, as are any files in it. - - As part of unmounting, `umount2' syncs the filesystem. - - If the unmounting is successful, the return value is zero. - Otherwise, it is `-1' and `errno' is set accordingly: - - `EPERM' - The process is not superuser. - - `EBUSY' - The filesystem cannot be unmounted because it is busy. E.g. - it contains a directory that is some process's working - directory or a file that some process has open. With some - filesystems in some cases, you can avoid this failure with - the `MNT_FORCE' option. - - `EINVAL' - FILE validly refers to a file, but that file is neither a - mount point nor a device special file of a currently mounted - filesystem. - - This function is not available on all systems. - - - Function: int umount (const char *FILE) - `umount' does the same thing as `umount2' with FLAGS set to - zeroes. It is more widely available than `umount2' but since it - lacks the possibility to forcefully unmount a filesystem is - deprecated when `umount2' is also available. - - -File: libc.info, Node: System Parameters, Prev: Filesystem Handling, Up: System Management - -System Parameters -================= - - This section describes the `sysctl' function, which gets and sets a -variety of system parameters. - - The symbols used in this section are declared in the file `sysctl.h'. - - - Function: int sysctl (int *NAMES, int NLEN, void *OLDVAL, - size_t *OLDLENP, void *NEWVAL, size_t NEWLEN) - - `sysctl' gets or sets a specified system parameter. There are so - many of these parameters that it is not practical to list them all - here, but here are some examples: - - * network domain name - - * paging parameters - - * network Address Resolution Protocol timeout time - - * maximum number of files that may be open - - * root filesystem device - - * when kernel was built - - The set of available parameters depends on the kernel - configuration and can change while the system is running, - particularly when you load and unload loadable kernel modules. - - The system parameters with which `syslog' is concerned are arranged - in a hierarchical structure like a hierarchical filesystem. To - identify a particular parameter, you specify a path through the - structure in a way analogous to specifying the pathname of a file. - Each component of the path is specified by an integer and each of - these integers has a macro defined for it by `sysctl.h'. NAMES is - the path, in the form of an array of integers. Each component of - the path is one element of the array, in order. NLEN is the - number of components in the path. - - For example, the first component of the path for all the paging - parameters is the value `CTL_VM'. For the free page thresholds, - the second component of the path is `VM_FREEPG'. So to get the - free page threshold values, make NAMES an array containing the two - elements `CTL_VM' and `VM_FREEPG' and make NLEN = 2. - - The format of the value of a parameter depends on the parameter. - Sometimes it is an integer; sometimes it is an ASCII string; - sometimes it is an elaborate structure. In the case of the free - page thresholds used in the example above, the parameter value is - a structure containing several integers. - - In any case, you identify a place to return the parameter's value - with OLDVAL and specify the amount of storage available at that - location as *OLDLENP. *OLDLENP does double duty because it is - also the output location that contains the actual length of the - returned value. - - If you don't want the parameter value returned, specify a null - pointer for OLDVAL. - - To set the parameter, specify the address and length of the new - value as NEWVAL and NEWLEN. If you don't want to set the - parameter, specify a null pointer as NEWVAL. - - If you get and set a parameter in the same `sysctl' call, the value - returned is the value of the parameter before it was set. - - Each system parameter has a set of permissions similar to the - permissions for a file (including the permissions on directories - in its path) that determine whether you may get or set it. For - the purposes of these permissions, every parameter is considered - to be owned by the superuser and Group 0 so processes with that - effective uid or gid may have more access to system parameters. - Unlike with files, the superuser does not invariably have full - permission to all system parameters, because some of them are - designed not to be changed ever. - - `sysctl' returns a zero return value if it succeeds. Otherwise, it - returns `-1' and sets `errno' appropriately. Besides the failures - that apply to all system calls, the following are the `errno' - codes for all possible failures: - - `EPERM' - The process is not permitted to access one of the components - of the path of the system parameter or is not permitted to - access the system parameter itself in the way (read or write) - that it requested. - - `ENOTDIR' - There is no system parameter corresponding to NAME. - - `EFAULT' - OLDVAL is not null, which means the process wanted to read - the parameter, but *OLDLENP is zero, so there is no place to - return it. - - `EINVAL' - * The process attempted to set a system parameter to a - value that is not valid for that parameter. - - * The space provided for the return of the system - parameter is not the right size for that parameter. - - `ENOMEM' - This value may be returned instead of the more correct - `EINVAL' in some cases where the space provided for the - return of the system parameter is too small. - - - If you have a Linux kernel with the `proc' filesystem, you can get -and set most of the same parameters by reading and writing to files in -the `sys' directory of the `proc' filesystem. In the `sys' directory, -the directory structure represents the hierarchical structure of the -parameters. E.g. you can display the free page thresholds with - cat /proc/sys/vm/freepages - - Some more traditional and more widely available, though less general, -GNU C library functions for getting and setting some of the same system -parameters are: - - * `getdomainname', `setdomainname' - - * `gethostname', `sethostname' (*Note Host Identification::.) - - * `uname' (*Note Platform Type::.) - - * `bdflush' - - -File: libc.info, Node: System Configuration, Next: Cryptographic Functions, Prev: System Management, Up: Top - -System Configuration Parameters -******************************* - - The functions and macros listed in this chapter give information -about configuration parameters of the operating system--for example, -capacity limits, presence of optional POSIX features, and the default -path for executable files (*note String Parameters::). - -* Menu: - -* General Limits:: Constants and functions that describe - various process-related limits that have - one uniform value for any given machine. -* System Options:: Optional POSIX features. -* Version Supported:: Version numbers of POSIX.1 and POSIX.2. -* Sysconf:: Getting specific configuration values - of general limits and system options. -* Minimums:: Minimum values for general limits. - -* Limits for Files:: Size limitations that pertain to individual files. - These can vary between file systems - or even from file to file. -* Options for Files:: Optional features that some files may support. -* File Minimums:: Minimum values for file limits. -* Pathconf:: Getting the limit values for a particular file. - -* Utility Limits:: Capacity limits of some POSIX.2 utility programs. -* Utility Minimums:: Minimum allowable values of those limits. - -* String Parameters:: Getting the default search path. - - -File: libc.info, Node: General Limits, Next: System Options, Up: System Configuration - -General Capacity Limits -======================= - - The POSIX.1 and POSIX.2 standards specify a number of parameters that -describe capacity limitations of the system.

The macros are -defined only if you include `unistd.h'. - - For the following macros, if the macro is defined in `unistd.h', -then the option is supported. Otherwise, the option may or may not be -supported; use `sysconf' to find out. *Note Sysconf::. - - - Macro: int _POSIX_JOB_CONTROL - If this symbol is defined, it indicates that the system supports - job control. Otherwise, the implementation behaves as if all - processes within a session belong to a single process group. - *Note Job Control::. - - - Macro: int _POSIX_SAVED_IDS - If this symbol is defined, it indicates that the system remembers - the effective user and group IDs of a process before it executes an - executable file with the set-user-ID or set-group-ID bits set, and - that explicitly changing the effective user or group IDs back to - these values is permitted. If this option is not defined, then if - a nonprivileged process changes its effective user or group ID to - the real user or group ID of the process, it can't change it back - again. *Note Enable/Disable Setuid::. - - For the following macros, if the macro is defined in `unistd.h', -then its value indicates whether the option is supported. A value of -`-1' means no, and any other value means yes. If the macro is not -defined, then the option may or may not be supported; use `sysconf' to -find out. *Note Sysconf::. - - - Macro: int _POSIX2_C_DEV - If this symbol is defined, it indicates that the system has the - POSIX.2 C compiler command, `c89'. The GNU C library always - defines this as `1', on the assumption that you would not have - installed it if you didn't have a C compiler. - - - Macro: int _POSIX2_FORT_DEV - If this symbol is defined, it indicates that the system has the - POSIX.2 Fortran compiler command, `fort77'. The GNU C library - never defines this, because we don't know what the system has. - - - Macro: int _POSIX2_FORT_RUN - If this symbol is defined, it indicates that the system has the - POSIX.2 `asa' command to interpret Fortran carriage control.

The following function handles this -in a convenient way. - - - Function: char * getpass (const char *PROMPT) - `getpass' outputs PROMPT, then reads a string in from the terminal - without echoing it. It tries to connect to the real terminal, - `/dev/tty', if possible, to encourage users not to put plaintext - passwords in files; otherwise, it uses `stdin' and `stderr'. - `getpass' also disables the INTR, QUIT, and SUSP characters on the - terminal using the `ISIG' terminal attribute (*note Local Modes::). - The terminal is flushed before and after `getpass', so that - characters of a mistyped password are not accidentally visible. - - In other C libraries, `getpass' may only return the first - `PASS_MAX' bytes of a password. The GNU C library has no limit, so - `PASS_MAX' is undefined. - - The prototype for this function is in `unistd.h'. `PASS_MAX' - would be defined in `limits.h'. - - This precise set of operations may not suit all possible situations. -In this case, it is recommended that users write their own `getpass' -substitute. For instance, a very simple substitute is as follows: - - #include - #include - - ssize_t - my_getpass (char **lineptr, size_t *n, FILE *stream) - { - struct termios old, new; - int nread; - - /* Turn echoing off and fail if we can't. */ - if (tcgetattr (fileno (stream), &old) != 0) - return -1; - new = old; - new.c_lflag &= ~ECHO; - if (tcsetattr (fileno (stream), TCSAFLUSH, &new) != 0) - return -1; - - /* Read the password. */ - nread = getline (lineptr, n, stream); - - /* Restore terminal. */ - (void) tcsetattr (fileno (stream), TCSAFLUSH, &old); - - return nread; - } - - The substitute takes the same parameters as `getline' (*note Line -Input::); the user must print any prompt desired. - - -File: libc.info, Node: crypt, Next: DES Encryption, Prev: getpass, Up: Cryptographic Functions - -Encrypting Passwords -==================== - - - Function: char * crypt (const char *KEY, const char *SALT) - The `crypt' function takes a password, KEY, as a string, and a - SALT character array which is described below, and returns a - printable ASCII string which starts with another salt. It is - believed that, given the output of the function, the best way to - find a KEY that will produce that output is to guess values of KEY - until the original value of KEY is found. - - The SALT parameter does two things. Firstly, it selects which - algorithm is used, the MD5-based one or the DES-based one. - Secondly, it makes life harder for someone trying to guess - passwords against a file containing many passwords; without a - SALT, an intruder can make a guess, run `crypt' on it once, and - compare the result with all the passwords. With a SALT, the - intruder must run `crypt' once for each different salt. - - For the MD5-based algorithm, the SALT should consist of the string - `$1$', followed by up to 8 characters, terminated by either - another `$' or the end of the string. The result of `crypt' will - be the SALT, followed by a `$' if the salt didn't end with one, - followed by 22 characters from the alphabet `./0-9A-Za-z', up to - 34 characters total. Every character in the KEY is significant. - - For the DES-based algorithm, the SALT should consist of two - characters from the alphabet `./0-9A-Za-z', and the result of - `crypt' will be those two characters followed by 11 more from the - same alphabet, 13 in total. Only the first 8 characters in the - KEY are significant. - - The MD5-based algorithm has no limit on the useful length of the - password used, and is slightly more secure. It is therefore - preferred over the DES-based algorithm. - - When the user enters their password for the first time, the SALT - should be set to a new string which is reasonably random. To - verify a password against the result of a previous call to - `crypt', pass the result of the previous call as the SALT. - - The following short program is an example of how to use `crypt' the -first time a password is entered. Note that the SALT generation is -just barely acceptable; in particular, it is not unique between -machines, and in many applications it would not be acceptable to let an -attacker know what time the user's password was last set. - - #include - #include - #include - #include - - int - main(void) - { - unsigned long seed[2]; - char salt[] = "$1$........"; - const char *const seedchars = - "./0123456789ABCDEFGHIJKLMNOPQRST" - "UVWXYZabcdefghijklmnopqrstuvwxyz"; - char *password; - int i; - - /* Generate a (not very) random seed. - You should do it better than this... */ - seed[0] = time(NULL); - seed[1] = getpid() ^ (seed[0] >> 14 & 0x30000); - - /* Turn it into printable characters from `seedchars'. */ - for (i = 0; i < 8; i++) - salt[3+i] = seedchars[(seed[i/5] >> (i%5)*6) & 0x3f]; - - /* Read in the user's password and encrypt it. */ - password = crypt(getpass("Password:"), salt); - - /* Print the results. */ - puts(password); - return 0; - } - - The next program shows how to verify a password.

The DES has been very -thoroughly analyzed since it was developed in the late 1970s, and no new -significant flaws have been found. - - However, the DES uses only a 56-bit key (plus 8 parity bits), and a -machine has been built in 1998 which can search through all possible -keys in about 6 days, which cost about US$200000; faster searches would -be possible with more money. This makes simple DES insecure for most -purposes, and NIST no longer permits new US government systems to use -simple DES. - - For serious encryption functionality, it is recommended that one of -the many free encryption libraries be used instead of these routines. - - The DES is a reversible operation which takes a 64-bit block and a -64-bit key, and produces another 64-bit block. Usually the bits are -numbered so that the most-significant bit, the first bit, of each block -is numbered 1. - - Under that numbering, every 8th bit of the key (the 8th, 16th, and so -on) is not used by the encryption algorithm itself. But the key must -have odd parity; that is, out of bits 1 through 8, and 9 through 16, and -so on, there must be an odd number of `1' bits, and this completely -specifies the unused bits. - - - Function: void setkey (const char *KEY) - The `setkey' function sets an internal data structure to be an - expanded form of KEY. KEY is specified as an array of 64 bits - each stored in a `char', the first bit is `key[0]' and the 64th - bit is `key[63]'. The KEY should have the correct parity. - - - Function: void encrypt (char *BLOCK, int EDFLAG) - The `encrypt' function encrypts BLOCK if EDFLAG is 0, otherwise it - decrypts BLOCK, using a key previously set by `setkey'. The - result is placed in BLOCK. - - Like `setkey', BLOCK is specified as an array of 64 bits each - stored in a `char', but there are no parity bits in BLOCK. - - - Function: void setkey_r (const char *KEY, struct crypt_data * DATA) - - Function: void encrypt_r (char *BLOCK, int EDFLAG, struct crypt_data - * DATA) - These are reentrant versions of `setkey' and `encrypt'. The only - difference is the extra parameter, which stores the expanded - version of KEY. Before calling `setkey_r' the first time, - `data->initialized' must be cleared to zero. - - The `setkey_r' and `encrypt_r' functions are GNU extensions. -`setkey', `encrypt', `setkey_r', and `encrypt_r' are defined in -`crypt.h'. - - - Function: int ecb_crypt (char *KEY, char *BLOCKS, unsigned LEN, - unsigned MODE) - The function `ecb_crypt' encrypts or decrypts one or more blocks - using DES. Each block is encrypted independently. - - The BLOCKS and the KEY are stored packed in 8-bit bytes, so that - the first bit of the key is the most-significant bit of `key[0]' - and the 63rd bit of the key is stored as the least-significant bit - of `key[7]'. The KEY should have the correct parity. - - LEN is the number of bytes in BLOCKS. It should be a multiple of - 8 (so that there is a whole number of blocks to encrypt). LEN is - limited to a maximum of `DES_MAXDATA' bytes. - - The result of the encryption replaces the input in BLOCKS. - - The MODE parameter is the bitwise OR of two of the following: - - `DES_ENCRYPT' - This constant, used in the MODE parameter, specifies that - BLOCKS is to be encrypted. - - `DES_DECRYPT' - This constant, used in the MODE parameter, specifies that - BLOCKS is to be decrypted. - - `DES_HW' - This constant, used in the MODE parameter, asks to use a - hardware device. If no hardware device is available, - encryption happens anyway, but in software. - - `DES_SW' - This constant, used in the MODE parameter, specifies that no - hardware device is to be used. - - The result of the function will be one of these values: - - `DESERR_NONE' - The encryption succeeded. - - `DESERR_NOHWDEVICE' - The encryption succeeded, but there was no hardware device - available. - - `DESERR_HWERROR' - The encryption failed because of a hardware problem. - - `DESERR_BADPARAM' - The encryption failed because of a bad parameter, for - instance LEN is not a multiple of 8 or LEN is larger than - `DES_MAXDATA'. - - - Function: int DES_FAILED (int ERR) - This macro returns 1 if ERR is a `success' result code from - `ecb_crypt' or `cbc_crypt', and 0 otherwise. - - - Function: int cbc_crypt (char *KEY, char *BLOCKS, unsigned LEN, - unsigned MODE, char *IVEC) - The function `cbc_crypt' encrypts or decrypts one or more blocks - using DES in Cipher Block Chaining mode. - - For encryption in CBC mode, each block is exclusive-ored with IVEC - before being encrypted, then IVEC is replaced with the result of - the encryption, then the next block is processed. Decryption is - the reverse of this process. - - This has the advantage that blocks which are the same before being - encrypted are very unlikely to be the same after being encrypted, - making it much harder to detect patterns in the data. - - Usually, IVEC is set to 8 random bytes before encryption starts. - Then the 8 random bytes are transmitted along with the encrypted - data (without themselves being encrypted), and passed back in as - IVEC for decryption. Another possibility is to set IVEC to 8 - zeroes initially, and have the first the block encrypted consist - of 8 random bytes. - - Otherwise, all the parameters are similar to those for `ecb_crypt'. - - - Function: void des_setparity (char *KEY) - The function `des_setparity' changes the 64-bit KEY, stored packed - in 8-bit bytes, to have odd parity by altering the low bits of - each byte. - - The `ecb_crypt', `cbc_crypt', and `des_setparity' functions and -their accompanying macros are all defined in the header -`rpc/des_crypt.h'. - - -File: libc.info, Node: Debugging Support, Next: POSIX Threads, Prev: Cryptographic Functions, Up: Top - -Debugging support -***************** - - Applications are usually debugged using dedicated debugger programs. -But sometimes this is not possible and, in any case, it is useful to -provide the developer with as much information as possible at the time -the problems are experienced.

The usual way to inspect a backtrace of a program -is to use an external debugger such as gdb. However, sometimes it is -useful to obtain a backtrace programmatically from within a program, -e.g., for the purposes of logging or diagnostics. - - The header file `execinfo.h' declares three functions that obtain -and manipulate backtraces of the current thread. - - - Function: int backtrace (void **BUFFER, int SIZE) - The `backtrace' function obtains a backtrace for the current - thread, as a list of pointers, and places the information into - BUFFER. The argument SIZE should be the number of `void *' - elements that will fit into BUFFER. The return value is the - actual number of entries of BUFFER that are obtained, and is at - most SIZE. - - The pointers placed in BUFFER are actually return addresses - obtained by inspecting the stack, one return address per stack - frame. - - Note that certain compiler optimizations may interfere with - obtaining a valid backtrace. Function inlining causes the inlined - function to not have a stack frame; tail call optimization - replaces one stack frame with another; frame pointer elimination - will stop `backtrace' from interpreting the stack contents - correctly. - - - Function: char ** backtrace_symbols (void *const *BUFFER, int SIZE) - The `backtrace_symbols' function translates the information - obtained from the `backtrace' function into an array of strings. - The argument BUFFER should be a pointer to an array of addresses - obtained via the `backtrace' function, and SIZE is the number of - entries in that array (the return value of `backtrace'). - - The return value is a pointer to an array of strings, which has - SIZE entries just like the array BUFFER. Each string contains a - printable representation of the corresponding element of BUFFER. - It includes the function name (if this can be determined), an - offset into the function, and the actual return address (in - hexadecimal). - - Currently, the function name and offset only be obtained on - systems that use the ELF binary format for programs and libraries. - On other systems, only the hexadecimal return address will be - present. Also, you may need to pass additional flags to the - linker to make the function names available to the program. (For - example, on systems using GNU ld, you must pass (`-rdynamic'.) - - The return value of `backtrace_symbols' is a pointer obtained via - the `malloc' function, and it is the responsibility of the caller - to `free' that pointer. Note that only the return value need be - freed, not the individual strings. - - The return value is `NULL' if sufficient memory for the strings - cannot be obtained. - - - Function: void backtrace_symbols_fd (void *const *BUFFER, int SIZE, - int FD) - The `backtrace_symbols_fd' function performs the same translation - as the function `backtrace_symbols' function. Instead of returning - the strings to the caller, it writes the strings to the file - descriptor FD, one per line. It does not use the `malloc' - function, and can therefore be used in situations where that - function might fail. - - The following program illustrates the use of these functions. Note -that the array to contain the return addresses returned by `backtrace' -is allocated on the stack. Therefore code like this can be used in -situations where the memory handling via `malloc' does not work anymore -(in which case the `backtrace_symbols' has to be replaced by a -`backtrace_symbols_fd' call as well).

With this technique, you do not -need to know how much data you will put in the object until you come to -the end of it. We call this the technique of "growing objects". The -special functions for adding data to the growing object are described -in this section. - - You don't need to do anything special when you start to grow an -object. Using one of the functions to add data to the object -automatically starts it. However, it is necessary to say explicitly -when the object is finished. This is done with the function -`obstack_finish'. - - The actual address of the object thus built up is not known until the -object is finished. Until then, it always remains possible that you -will add so much data that the object must be copied into a new chunk. - - While the obstack is in use for a growing object, you cannot use it -for ordinary allocation of another object. If you try to do so, the -space already added to the growing object will become part of the other -object. - - - Function: void obstack_blank (struct obstack *OBSTACK-PTR, int SIZE) - The most basic function for adding to a growing object is - `obstack_blank', which adds space without initializing it. - - - Function: void obstack_grow (struct obstack *OBSTACK-PTR, void - *DATA, int SIZE) - To add a block of initialized space, use `obstack_grow', which is - the growing-object analogue of `obstack_copy'. It adds SIZE bytes - of data to the growing object, copying the contents from DATA. - - - Function: void obstack_grow0 (struct obstack *OBSTACK-PTR, void - *DATA, int SIZE) - This is the growing-object analogue of `obstack_copy0'. It adds - SIZE bytes copied from DATA, followed by an additional null - character. - - - Function: void obstack_1grow (struct obstack *OBSTACK-PTR, char C) - To add one character at a time, use the function `obstack_1grow'. - It adds a single byte containing C to the growing object. - - - Function: void obstack_ptr_grow (struct obstack *OBSTACK-PTR, void - *DATA) - Adding the value of a pointer one can use the function - `obstack_ptr_grow'. It adds `sizeof (void *)' bytes containing - the value of DATA. - - - Function: void obstack_int_grow (struct obstack *OBSTACK-PTR, int - DATA) - A single value of type `int' can be added by using the - `obstack_int_grow' function. It adds `sizeof (int)' bytes to the - growing object and initializes them with the value of DATA. - - - Function: void * obstack_finish (struct obstack *OBSTACK-PTR) - When you are finished growing the object, use the function - `obstack_finish' to close it off and return its final address. - - Once you have finished the object, the obstack is available for - ordinary allocation or for growing another object. - - This function can return a null pointer under the same conditions - as `obstack_alloc' (*note Allocation in an Obstack::). - - When you build an object by growing it, you will probably need to -know afterward how long it became. You need not keep track of this as -you grow the object, because you can find out the length from the -obstack just before finishing the object with the function -`obstack_object_size', declared as follows: - - - Function: int obstack_object_size (struct obstack *OBSTACK-PTR) - This function returns the current size of the growing object, in - bytes. Remember to call this function _before_ finishing the - object. After it is finished, `obstack_object_size' will return - zero. - - If you have started growing an object and wish to cancel it, you -should finish it and then free it, like this: - - obstack_free (obstack_ptr, obstack_finish (obstack_ptr)); - -This has no effect if no object was growing. - - You can use `obstack_blank' with a negative size argument to make -the current object smaller. Just don't try to shrink it beyond zero -length--there's no telling what will happen if you do that. - - -File: libc.info, Node: Extra Fast Growing, Next: Status of an Obstack, Prev: Growing Objects, Up: Obstacks - -Extra Fast Growing Objects -.......................... - - The usual functions for growing objects incur overhead for checking -whether there is room for the new growth in the current chunk. If you -are frequently constructing objects in small steps of growth, this -overhead can be significant. - - You can reduce the overhead by using special "fast growth" functions -that grow the object without checking. In order to have a robust -program, you must do the checking yourself. If you do this checking in -the simplest way each time you are about to add data to the object, you -have not saved anything, because that is what the ordinary growth -functions do. But if you can arrange to check less often, or check -more efficiently, then you make the program faster. - - The function `obstack_room' returns the amount of room available in -the current chunk. It is declared as follows: - - - Function: int obstack_room (struct obstack *OBSTACK-PTR) - This returns the number of bytes that can be added safely to the - current growing object (or to an object about to be started) in - obstack OBSTACK using the fast growth functions. - - While you know there is room, you can use these fast growth functions -for adding data to a growing object: - - - Function: void obstack_1grow_fast (struct obstack *OBSTACK-PTR, char - C) - The function `obstack_1grow_fast' adds one byte containing the - character C to the growing object in obstack OBSTACK-PTR. - - - Function: void obstack_ptr_grow_fast (struct obstack *OBSTACK-PTR, - void *DATA) - The function `obstack_ptr_grow_fast' adds `sizeof (void *)' bytes - containing the value of DATA to the growing object in obstack - OBSTACK-PTR. - - - Function: void obstack_int_grow_fast (struct obstack *OBSTACK-PTR, - int DATA) - The function `obstack_int_grow_fast' adds `sizeof (int)' bytes - containing the value of DATA to the growing object in obstack - OBSTACK-PTR. - - - Function: void obstack_blank_fast (struct obstack *OBSTACK-PTR, int - SIZE) - The function `obstack_blank_fast' adds SIZE bytes to the growing - object in obstack OBSTACK-PTR without initializing them. - - When you check for space using `obstack_room' and there is not -enough room for what you want to add, the fast growth functions are not -safe. In this case, simply use the corresponding ordinary growth -function instead. Very soon this will copy the object to a new chunk; -then there will be lots of room available again. - - So, each time you use an ordinary growth function, check afterward -for sufficient space using `obstack_room'. Once the object is copied -to a new chunk, there will be plenty of space again, so the program will -start using the fast growth functions again. - - Here is an example: - - void - add_string (struct obstack *obstack, const char *ptr, int len) - { - while (len > 0) - { - int room = obstack_room (obstack); - if (room == 0) - { - /* Not enough room.

You can use them to learn about an object -while still growing it. - - - Function: void * obstack_base (struct obstack *OBSTACK-PTR) - This function returns the tentative address of the beginning of the - currently growing object in OBSTACK-PTR. If you finish the object - immediately, it will have that address. If you make it larger - first, it may outgrow the current chunk--then its address will - change! - - If no object is growing, this value says where the next object you - allocate will start (once again assuming it fits in the current - chunk). - - - Function: void * obstack_next_free (struct obstack *OBSTACK-PTR) - This function returns the address of the first free byte in the - current chunk of obstack OBSTACK-PTR. This is the end of the - currently growing object. If no object is growing, - `obstack_next_free' returns the same value as `obstack_base'. - - - Function: int obstack_object_size (struct obstack *OBSTACK-PTR) - This function returns the size in bytes of the currently growing - object.

By default, this boundary is 4 bytes. - - To access an obstack's alignment boundary, use the macro -`obstack_alignment_mask', whose function prototype looks like this: - - - Macro: int obstack_alignment_mask (struct obstack *OBSTACK-PTR) - The value is a bit mask; a bit that is 1 indicates that the - corresponding bit in the address of an object should be 0. The - mask value should be one less than a power of 2; the effect is - that all object addresses are multiples of that power of 2. The - default value of the mask is 3, so that addresses are multiples of - 4. A mask value of 0 means an object can start on any multiple of - 1 (that is, no alignment is required). - - The expansion of the macro `obstack_alignment_mask' is an lvalue, - so you can alter the mask by assignment. For example, this - statement: - - obstack_alignment_mask (obstack_ptr) = 0; - - has the effect of turning off alignment processing in the - specified obstack. - - Note that a change in alignment mask does not take effect until -_after_ the next time an object is allocated or finished in the -obstack. If you are not growing an object, you can make the new -alignment mask take effect immediately by calling `obstack_finish'. -This will finish a zero-length object and then do proper alignment for -the next object. - - -File: libc.info, Node: Obstack Chunks, Next: Summary of Obstacks, Prev: Obstacks Data Alignment, Up: Obstacks - -Obstack Chunks -.............. - - Obstacks work by allocating space for themselves in large chunks, and -then parceling out space in the chunks to satisfy your requests. Chunks -are normally 4096 bytes long unless you specify a different chunk size. -The chunk size includes 8 bytes of overhead that are not actually used -for storing objects. Regardless of the specified size, longer chunks -will be allocated when necessary for long objects. - - The obstack library allocates chunks by calling the function -`obstack_chunk_alloc', which you must define. When a chunk is no -longer needed because you have freed all the objects in it, the obstack -library frees the chunk by calling `obstack_chunk_free', which you must -also define. - - These two must be defined (as macros) or declared (as functions) in -each source file that uses `obstack_init' (*note Creating Obstacks::). -Most often they are defined as macros like this: - - #define obstack_chunk_alloc malloc - #define obstack_chunk_free free - - Note that these are simple macros (no arguments). Macro definitions -with arguments will not work! It is necessary that -`obstack_chunk_alloc' or `obstack_chunk_free', alone, expand into a -function name if it is not itself a function name. - - If you allocate chunks with `malloc', the chunk size should be a -power of 2. The default chunk size, 4096, was chosen because it is long -enough to satisfy many typical requests on the obstack yet short enough -not to waste too much memory in the portion of the last chunk not yet -used. - - - Macro: int obstack_chunk_size (struct obstack *OBSTACK-PTR) - This returns the chunk size of the given obstack. - - Since this macro expands to an lvalue, you can specify a new chunk -size by assigning it a new value. Doing so does not affect the chunks -already allocated, but will change the size of chunks allocated for -that particular obstack in the future. It is unlikely to be useful to -make the chunk size smaller, but making it larger might improve -efficiency if you are allocating many objects whose size is comparable -to the chunk size.

Let's - change `open2' (*note Alloca Example::) to use this subroutine: - - int - open2 (char *str1, char *str2, int flags, int mode) - { - char *name = (char *) alloca (strlen (str1) + strlen (str2) + 1); - stpcpy (stpcpy (name, str1), str2); - return open_or_report_error (name, flags, mode); - } - - Because of the way `alloca' works, the memory it allocates is - freed even when an error occurs, with no special effort required. - - By contrast, the previous definition of `open2' (which uses - `malloc' and `free') would develop a memory leak if it were - changed in this way. Even if you are willing to make more changes - to fix it, there is no easy way to do so. - - -File: libc.info, Node: Disadvantages of Alloca, Next: GNU C Variable-Size Arrays, Prev: Advantages of Alloca, Up: Variable Size Automatic - -Disadvantages of `alloca' -......................... - - These are the disadvantages of `alloca' in comparison with `malloc': - - * If you try to allocate more memory than the machine can provide, - you don't get a clean error message. Instead you get a fatal - signal like the one you would get from an infinite recursion; - probably a segmentation violation (*note Program Error Signals::). - - * Some non-GNU systems fail to support `alloca', so it is less - portable. However, a slower emulation of `alloca' written in C is - available for use on systems with this deficiency. - - -File: libc.info, Node: GNU C Variable-Size Arrays, Prev: Disadvantages of Alloca, Up: Variable Size Automatic - -GNU C Variable-Size Arrays -.......................... - - In GNU C, you can replace most uses of `alloca' with an array of -variable size. Here is how `open2' would look then: - - int open2 (char *str1, char *str2, int flags, int mode) - { - char name[strlen (str1) + strlen (str2) + 1]; - stpcpy (stpcpy (name, str1), str2); - return open (name, flags, mode); - } - - But `alloca' is not always equivalent to a variable-sized array, for -several reasons: - - * A variable size array's space is freed at the end of the scope of - the name of the array. The space allocated with `alloca' remains - until the end of the function. - - * It is possible to use `alloca' within a loop, allocating an - additional block on each iteration. This is impossible with - variable-sized arrays. - - *Note:* If you mix use of `alloca' and variable-sized arrays within -one function, exiting a scope in which a variable-sized array was -declared frees all blocks allocated with `alloca' during the execution -of that scope. - - -File: libc.info, Node: Resizing the Data Segment, Prev: Locking Pages, Up: Memory - -Resizing the Data Segment -========================= - - The symbols in this section are declared in `unistd.h'. - - You will not normally use the functions in this section, because the -functions described in *Note Memory Allocation:: are easier to use. -Those are interfaces to a GNU C Library memory allocator that uses the -functions below itself.

This is called -"locking" a page. - - The functions in this chapter lock and unlock the calling process' -pages. - -* Menu: - -* Why Lock Pages:: Reasons to read this section. -* Locked Memory Details:: Everything you need to know locked - memory -* Page Lock Functions:: Here's how to do it. - - -File: libc.info, Node: Why Lock Pages, Next: Locked Memory Details, Up: Locking Pages - -Why Lock Pages --------------- - - Because page faults cause paged out pages to be paged in -transparently, a process rarely needs to be concerned about locking -pages. However, there are two reasons people sometimes are: - - * Speed. A page fault is transparent only insofar as the process is - not sensitive to how long it takes to do a simple memory access. - Time-critical processes, especially realtime processes, may not be - able to wait or may not be able to tolerate variance in execution - speed. - - A process that needs to lock pages for this reason probably also - needs priority among other processes for use of the CPU. *Note - Priority::. - - In some cases, the programmer knows better than the system's demand - paging allocator which pages should remain in real memory to - optimize system performance. In this case, locking pages can help. - - * Privacy. If you keep secrets in virtual memory and that virtual - memory gets paged out, that increases the chance that the secrets - will get out. If a password gets written out to disk swap space, - for example, it might still be there long after virtual and real - memory have been wiped clean. - - - Be aware that when you lock a page, that's one fewer page frame that -can be used to back other virtual memory (by the same or other -processes), which can mean more page faults, which means the system -runs more slowly. In fact, if you lock enough memory, some programs -may not be able to run at all for lack of real memory. - - -File: libc.info, Node: Locked Memory Details, Next: Page Lock Functions, Prev: Why Lock Pages, Up: Locking Pages - -Locked Memory Details ---------------------- - - A memory lock is associated with a virtual page, not a real frame. -The paging rule is: If a frame backs at least one locked page, don't -page it out. - - Memory locks do not stack. I.e. you can't lock a particular page -twice so that it has to be unlocked twice before it is truly unlocked. -It is either locked or it isn't. - - A memory lock persists until the process that owns the memory -explicitly unlocks it. (But process termination and exec cause the -virtual memory to cease to exist, which you might say means it isn't -locked any more). - - Memory locks are not inherited by child processes. (But note that -on a modern Unix system, immediately after a fork, the parent's and the -child's virtual address space are backed by the same real page frames, -so the child enjoys the parent's locks). *Note Creating a Process::. - - Because of its ability to impact other processes, only the superuser -can lock a page. Any process can unlock its own page. - - The system sets limits on the amount of memory a process can have -locked and the amount of real memory it can have dedicated to it. -*Note Limits on Resources::. - - In Linux, locked pages aren't as locked as you might think. Two -virtual pages that are not shared memory can nonetheless be backed by -the same real frame. The kernel does this in the name of efficiency -when it knows both virtual pages contain identical data, and does it -even if one or both of the virtual pages are locked. - - But when a process modifies one of those pages, the kernel must get -it a separate frame and fill it with the page's data. This is known as -a "copy-on-write page fault". It takes a small amount of time and in a -pathological case, getting that frame may require I/O. - - To make sure this doesn't happen to your program, don't just lock the -pages. Write to them as well, unless you know you won't write to them -ever. And to make sure you have pre-allocated frames for your stack, -enter a scope that declares a C automatic variable larger than the -maximum stack size you will need, set it to something, then return from -its scope. - - -File: libc.info, Node: Page Lock Functions, Prev: Locked Memory Details, Up: Locking Pages - -Functions To Lock And Unlock Pages ----------------------------------- - - The symbols in this section are declared in `sys/mman.h'.

They _are_ available with a Linux kernel. - - *Portability Note:* POSIX.1b requires that when the `mlock' and -`munlock' functions are available, the file `unistd.h' define the macro -`_POSIX_MEMLOCK_RANGE' and the file `limits.h' define the macro -`PAGESIZE' to be the size of a memory page in bytes. It requires that -when the `mlockall' and `munlockall' functions are available, the -`unistd.h' file define the macro `_POSIX_MEMLOCK'. The GNU C library -conforms to this requirement. - - - Function: int mlock (const void *ADDR, size_t LEN) - `mlock' locks a range of the calling process' virtual pages. - - The range of memory starts at address ADDR and is LEN bytes long. - Actually, since you must lock whole pages, it is the range of - pages that include any part of the specified range. - - When the function returns successfully, each of those pages is - backed by (connected to) a real frame (is resident) and is marked - to stay that way.

You unlock - memory with `munlock' or `munlockall'. - - To avoid all page faults in a C program, you have to use - `mlockall', because some of the memory a program uses is hidden - from the C code, e.g. the stack and automatic variables, and you - wouldn't know what address to tell `mlock'. - - - - Function: int munlock (const void *ADDR, size_t LEN) - `mlock' unlocks a range of the calling process' virtual pages. - - `munlock' is the inverse of `mlock' and functions completely - analogously to `mlock', except that there is no `EPERM' failure. - - - - Function: int mlockall (int FLAGS) - `mlockall' locks all the pages in a process' virtual memory address - space, and/or any that are added to it in the future.

Otherwise it returns 0. - - - Function: int pthread_setcanceltype (int TYPE, int *OLDTYPE) - `pthread_setcanceltype' changes the type of responses to - cancellation requests for the calling thread: asynchronous - (immediate) or deferred. The TYPE argument is the new - cancellation type: either `PTHREAD_CANCEL_ASYNCHRONOUS' to cancel - the calling thread as soon as the cancellation request is - received, or `PTHREAD_CANCEL_DEFERRED' to keep the cancellation - request pending until the next cancellation point.

Cleanup handlers are installed and removed following a -stack-like discipline. - - The purpose of cleanup handlers is to free the resources that a -thread may hold at the time it terminates. In particular, if a thread -exits or is canceled while it owns a locked mutex, the mutex will -remain locked forever and prevent other threads from executing -normally. The best way to avoid this is, just before locking the mutex, -to install a cleanup handler whose effect is to unlock the mutex. -Cleanup handlers can be used similarly to free blocks allocated with -`malloc' or close file descriptors on thread termination. - - Here is how to lock a mutex MUT in such a way that it will be -unlocked if the thread is canceled while MUT is locked: - - pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut); - pthread_mutex_lock(&mut); - /* do some work */ - pthread_mutex_unlock(&mut); - pthread_cleanup_pop(0); - - Equivalently, the last two lines can be replaced by - - pthread_cleanup_pop(1); - - Notice that the code above is safe only in deferred cancellation mode -(see `pthread_setcanceltype'). In asynchronous cancellation mode, a -cancellation can occur between `pthread_cleanup_push' and -`pthread_mutex_lock', or between `pthread_mutex_unlock' and -`pthread_cleanup_pop', resulting in both cases in the thread trying to -unlock a mutex not locked by the current thread. This is the main -reason why asynchronous cancellation is difficult to use. - - If the code above must also work in asynchronous cancellation mode, -then it must switch to deferred mode for locking and unlocking the -mutex: - - pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype); - pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut); - pthread_mutex_lock(&mut); - /* do some work */ - pthread_cleanup_pop(1); - pthread_setcanceltype(oldtype, NULL); - - The code above can be rewritten in a more compact and efficient way, -using the non-portable functions `pthread_cleanup_push_defer_np' and -`pthread_cleanup_pop_restore_np': - - pthread_cleanup_push_defer_np(pthread_mutex_unlock, (void *) &mut); - pthread_mutex_lock(&mut); - /* do some work */ - pthread_cleanup_pop_restore_np(1); - - - Function: void pthread_cleanup_push (void (*ROUTINE) (void *), void - *ARG) - `pthread_cleanup_push' installs the ROUTINE function with argument - ARG as a cleanup handler. From this point on to the matching - `pthread_cleanup_pop', the function ROUTINE will be called with - arguments ARG when the thread terminates, either through - `pthread_exit' or by cancellation. If several cleanup handlers are - active at that point, they are called in LIFO order: the most - recently installed handler is called first. - - - Function: void pthread_cleanup_pop (int EXECUTE) - `pthread_cleanup_pop' removes the most recently installed cleanup - handler. If the EXECUTE argument is not 0, it also executes the - handler, by calling the ROUTINE function with arguments ARG. If - the EXECUTE argument is 0, the handler is only removed but not - executed. - - Matching pairs of `pthread_cleanup_push' and `pthread_cleanup_pop' -must occur in the same function, at the same level of block nesting. -Actually, `pthread_cleanup_push' and `pthread_cleanup_pop' are macros, -and the expansion of `pthread_cleanup_push' introduces an open brace -`{' with the matching closing brace `}' being introduced by the -expansion of the matching `pthread_cleanup_pop'. - - - Function: void pthread_cleanup_push_defer_np (void (*ROUTINE) (void - *), void *ARG) - `pthread_cleanup_push_defer_np' is a non-portable extension that - combines `pthread_cleanup_push' and `pthread_setcanceltype'. It - pushes a cleanup handler just as `pthread_cleanup_push' does, but - also saves the current cancellation type and sets it to deferred - cancellation. This ensures that the cleanup mechanism is effective - even if the thread was initially in asynchronous cancellation mode. - - - Function: void pthread_cleanup_pop_restore_np (int EXECUTE) - `pthread_cleanup_pop_restore_np' pops a cleanup handler introduced - by `pthread_cleanup_push_defer_np', and restores the cancellation - type to its value at the time `pthread_cleanup_push_defer_np' was - called. - - `pthread_cleanup_push_defer_np' and `pthread_cleanup_pop_restore_np' -must occur in matching pairs, at the same level of block nesting. - - The sequence - - pthread_cleanup_push_defer_np(routine, arg); - ... - pthread_cleanup_pop_defer_np(execute); - -is functionally equivalent to (but more compact and efficient than) - - { - int oldtype; - pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype); - pthread_cleanup_push(routine, arg); - ... - pthread_cleanup_pop(execute); - pthread_setcanceltype(oldtype, NULL); - } - - -File: libc.info, Node: Mutexes, Next: Condition Variables, Prev: Cleanup Handlers, Up: POSIX Threads - -Mutexes -======= - - A mutex is a MUTual EXclusion device, and is useful for protecting -shared data structures from concurrent modifications, and implementing -critical sections and monitors. - - A mutex has two possible states: unlocked (not owned by any thread), -and locked (owned by one thread).

A thread attempting to lock a mutex -that is already locked by another thread is suspended until the owning -thread unlocks the mutex first. - - None of the mutex functions is a cancellation point, not even -`pthread_mutex_lock', in spite of the fact that it can suspend a thread -for arbitrary durations. This way, the status of mutexes at -cancellation points is predictable, allowing cancellation handlers to -unlock precisely those mutexes that need to be unlocked before the -thread stops executing. Consequently, threads using deferred -cancellation should never hold a mutex for extended periods of time. - - It is not safe to call mutex functions from a signal handler.

A destructor - function might, however, re-associate non-`NULL' values to that - key or some other key. To deal with this, if after all the - destructors have been called for all non-`NULL' values, there are - still some non-`NULL' values with associated destructors, then the - process is repeated.

If the delivered signal has a signal handler - function attached, that function is _not_ called. - - `sigwait' is a cancellation point. It always returns 0. - - For `sigwait' to work reliably, the signals being waited for must be -blocked in all threads, not only in the calling thread, since otherwise -the POSIX semantics for signal delivery do not guarantee that it's the -thread doing the `sigwait' that will receive the signal. The best way -to achieve this is block those signals before any threads are created, -and never unblock them in the program other than by calling `sigwait'. - - Signal handling in LinuxThreads departs significantly from the POSIX -standard. According to the standard, "asynchronous" (external) signals -are addressed to the whole process (the collection of all threads), -which then delivers them to one particular thread. The thread that -actually receives the signal is any thread that does not currently block -the signal. - - In LinuxThreads, each thread is actually a kernel process with its -own PID, so external signals are always directed to one particular -thread. If, for instance, another thread is blocked in `sigwait' on -that signal, it will not be restarted. - - The LinuxThreads implementation of `sigwait' installs dummy signal -handlers for the signals in SET for the duration of the wait. Since -signal handlers are shared between all threads, other threads must not -attach their own signal handlers to these signals, or alternatively -they should all block these signals (which is recommended anyway). - diff -u -udbrN glibc-2.3.2/manual/libc.info-51 glibc-2.3.2-200304020432/manual/libc.info-51 --- glibc-2.3.2/manual/libc.info-51 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-51 Thu Jan 1 01:00:00 1970 @@ -1,1113 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

Not only are the semantics -tricky, but you may need to write code that does the right thing at -fork time even if that code doesn't use the `fork' function. Moreover, -you need to be aware of interaction between `fork' and some library -features like `pthread_once' and stdio streams. - - When `fork' is called by one of the threads of a process, it creates -a new process which is copy of the calling process. Effectively, in -addition to copying certain system objects, the function takes a -snapshot of the memory areas of the parent process, and creates -identical areas in the child. To make matters more complicated, with -threads it's possible for two or more threads to concurrently call fork -to create two or more child processes. - - The child process has a copy of the address space of the parent, but -it does not inherit any of its threads. Execution of the child process -is carried out by a new thread which returns from `fork' function with -a return value of zero; it is the only thread in the child process. -Because threads are not inherited across fork, issues arise. At the -time of the call to `fork', threads in the parent process other than -the one calling `fork' may have been executing critical regions of -code. As a result, the child process may get a copy of objects that -are not in a well-defined state. This potential problem affects all -components of the program. - - Any program component which will continue being used in a child -process must correctly handle its state during `fork'. For this -purpose, the POSIX interface provides the special function -`pthread_atfork' for installing pointers to handler functions which are -called from within `fork'. - - - Function: int pthread_atfork (void (*PREPARE)(void), void - (*PARENT)(void), void (*CHILD)(void)) - `pthread_atfork' registers handler functions to be called just - before and just after a new process is created with `fork'. The - PREPARE handler will be called from the parent process, just - before the new process is created. The PARENT handler will be - called from the parent process, just before `fork' returns. The - CHILD handler will be called from the child process, just before - `fork' returns. - - `pthread_atfork' returns 0 on success and a non-zero error code on - error. - - One or more of the three handlers PREPARE, PARENT and CHILD can be - given as `NULL', meaning that no handler needs to be called at the - corresponding point. - - `pthread_atfork' can be called several times to install several - sets of handlers. At `fork' time, the PREPARE handlers are called - in LIFO order (last added with `pthread_atfork', first called - before `fork'), while the PARENT and CHILD handlers are called in - FIFO order (first added, first called). - - If there is insufficient memory available to register the handlers, - `pthread_atfork' fails and returns `ENOMEM'. Otherwise it returns - 0. - - The functions `fork' and `pthread_atfork' must not be regarded as - reentrant from the context of the handlers. That is to say, if a - `pthread_atfork' handler invoked from within `fork' calls - `pthread_atfork' or `fork', the behavior is undefined. - - Registering a triplet of handlers is an atomic operation with - respect to fork. If new handlers are registered at about the same - time as a fork occurs, either all three handlers will be called, - or none of them will be called. - - The handlers are inherited by the child process, and there is no - way to remove them, short of using `exec' to load a new pocess - image. - - - To understand the purpose of `pthread_atfork', recall that `fork' -duplicates the whole memory space, including mutexes in their current -locking state, but only the calling thread: other threads are not -running in the child process. The mutexes are not usable after the -`fork' and must be initialized with `pthread_mutex_init' in the child -process. This is a limitation of the current implementation and might -or might not be present in future versions. - - To avoid this, install handlers with `pthread_atfork' as follows: -have the PREPARE handler lock the mutexes (in locking order), and the -PARENT handler unlock the mutexes. The CHILD handler should reset the -mutexes using `pthread_mutex_init', as well as any other -synchronization objects such as condition variables. - - Locking the global mutexes before the fork ensures that all other -threads are locked out of the critical regions of code protected by -those mutexes. Thus when `fork' takes a snapshot of the parent's -address space, that snapshot will copy valid, stable data. Resetting -the synchronization objects in the child process will ensure they are -properly cleansed of any artifacts from the threading subsystem of the -parent process. For example, a mutex may inherit a wait queue of -threads waiting for the lock; this wait queue makes no sense in the -child process. Initializing the mutex takes care of this. - - -File: libc.info, Node: Streams and Fork, Next: Miscellaneous Thread Functions, Prev: Threads and Fork, Up: POSIX Threads - -Streams and Fork -================ - - The GNU standard I/O library has an internal mutex which guards the -internal linked list of all standard C FILE objects. This mutex is -properly taken care of during `fork' so that the child receives an -intact copy of the list. This allows the `fopen' function, and related -stream-creating functions, to work correctly in the child process, -since these functions need to insert into the list. - - However, the individual stream locks are not completely taken care -of. Thus unless the multithreaded application takes special -precautions in its use of `fork', the child process might not be able -to safely use the streams that it inherited from the parent. In -general, for any given open stream in the parent that is to be used by -the child process, the application must ensure that that stream is not -in use by another thread when `fork' is called. Otherwise an -inconsistent copy of the stream object be produced. An easy way to -ensure this is to use `flockfile' to lock the stream prior to calling -`fork' and then unlock it with `funlockfile' inside the parent process, -provided that the parent's threads properly honor these locks. Nothing -special needs to be done in the child process, since the library -internally resets all stream locks. - - Note that the stream locks are not shared between the parent and -child. For example, even if you ensure that, say, the stream `stdout' -is properly treated and can be safely used in the child, the stream -locks do not provide an exclusion mechanism between the parent and -child. If both processes write to `stdout', strangely interleaved -output may result regardless of the explicit use of `flockfile' or -implicit locks. - - Also note that these provisions are a GNU extension; other systems -might not provide any way for streams to be used in the child of a -multithreaded process. POSIX requires that such a child process -confines itself to calling only asynchronous safe functions, which -excludes much of the library, including standard I/O. - - -File: libc.info, Node: Miscellaneous Thread Functions, Prev: Streams and Fork, Up: POSIX Threads - -Miscellaneous Thread Functions -============================== - - - Function: pthread_t pthread_self (VOID) - `pthread_self' returns the thread identifier for the calling - thread. - - - Function: int pthread_equal (pthread_t thread1, pthread_t thread2) - `pthread_equal' determines if two thread identifiers refer to the - same thread. - - A non-zero value is returned if THREAD1 and THREAD2 refer to the - same thread.

When you -define a function, you specify the data type for each argument. Every -call to the function should supply the expected number of arguments, -with types that can be converted to the specified ones. Thus, if the -function `foo' is declared with `int foo (int, char *);' then you must -call it with two arguments, a number (any kind will do) and a string -pointer. - - But some functions perform operations that can meaningfully accept an -unlimited number of arguments. - - In some cases a function can handle any number of values by -operating on all of them as a block. For example, consider a function -that allocates a one-dimensional array with `malloc' to hold a -specified set of values. This operation makes sense for any number of -values, as long as the length of the array corresponds to that number. -Without facilities for variable arguments, you would have to define a -separate function for each possible array size. - - The library function `printf' (*note Formatted Output::) is an -example of another class of function where variable arguments are -useful. This function prints its arguments (which can vary in type as -well as number) under the control of a format template string. - - These are good reasons to define a "variadic" function which can -handle as many arguments as the caller chooses to pass. - - Some functions such as `open' take a fixed set of arguments, but -occasionally ignore the last few. Strict adherence to ISO C requires -these functions to be defined as variadic; in practice, however, the GNU -C compiler and most other C compilers let you define such a function to -take a fixed set of arguments--the most it can ever use--and then only -_declare_ the function as variadic (or not declare its arguments at -all!). - - -File: libc.info, Node: How Variadic, Next: Variadic Example, Prev: Why Variadic, Up: Variadic Functions - -How Variadic Functions are Defined and Used -------------------------------------------- - - Defining and using a variadic function involves three steps: - - * _Define_ the function as variadic, using an ellipsis (`...') in - the argument list, and using special macros to access the variable - arguments. *Note Receiving Arguments::. - - * _Declare_ the function as variadic, using a prototype with an - ellipsis (`...'), in all the files which call it. *Note Variadic - Prototypes::. - - * _Call_ the function by writing the fixed arguments followed by the - additional variable arguments. *Note Calling Variadics::. - -* Menu: - -* Variadic Prototypes:: How to make a prototype for a function - with variable arguments. -* Receiving Arguments:: Steps you must follow to access the - optional argument values. -* How Many Arguments:: How to decide whether there are more arguments. -* Calling Variadics:: Things you need to know about calling - variable arguments functions. -* Argument Macros:: Detailed specification of the macros - for accessing variable arguments. -* Old Varargs:: The pre-ISO way of defining variadic functions. - - -File: libc.info, Node: Variadic Prototypes, Next: Receiving Arguments, Up: How Variadic - -Syntax for Variable Arguments -............................. - - A function that accepts a variable number of arguments must be -declared with a prototype that says so.

How can you access them? - - The only way to access them is sequentially, in the order they were -written, and you must use special macros from `stdarg.h' in the -following three step process: - - 1. You initialize an argument pointer variable of type `va_list' using - `va_start'. The argument pointer when initialized points to the - first optional argument. - - 2. You access the optional arguments by successive calls to `va_arg'. - The first call to `va_arg' gives you the first optional argument, - the next call gives you the second, and so on. - - You can stop at any time if you wish to ignore any remaining - optional arguments. It is perfectly all right for a function to - access fewer arguments than were supplied in the call, but you - will get garbage values if you try to access too many arguments. - - 3. You indicate that you are finished with the argument pointer - variable by calling `va_end'. - - (In practice, with most C compilers, calling `va_end' does nothing. - This is always true in the GNU C compiler. But you might as well - call `va_end' just in case your program is someday compiled with a - peculiar compiler.) - - *Note Argument Macros::, for the full definitions of `va_start', -`va_arg' and `va_end'. - - Steps 1 and 3 must be performed in the function that accepts the -optional arguments. However, you can pass the `va_list' variable as an -argument to another function and perform all or part of step 2 there. - - You can perform the entire sequence of three steps multiple times -within a single function invocation. If you want to ignore the optional -arguments, you can do these steps zero times. - - You can have more than one argument pointer variable if you like. -You can initialize each variable with `va_start' when you wish, and -then you can fetch arguments with each argument pointer as you wish. -Each argument pointer variable will sequence through the same set of -argument values, but at its own pace. - - *Portability note:* With some compilers, once you pass an argument -pointer value to a subroutine, you must not keep using the same -argument pointer value after that subroutine returns. For full -portability, you should just pass it to `va_end'. This is actually an -ISO C requirement, but most ANSI C compilers work happily regardless. - - -File: libc.info, Node: How Many Arguments, Next: Calling Variadics, Prev: Receiving Arguments, Up: How Variadic - -How Many Arguments Were Supplied -................................ - - There is no general way for a function to determine the number and -type of the optional arguments it was called with. So whoever designs -the function typically designs a convention for the caller to specify -the number and type of arguments. It is up to you to define an -appropriate calling convention for each variadic function, and write -all calls accordingly. - - One kind of calling convention is to pass the number of optional -arguments as one of the fixed arguments. This convention works provided -all of the optional arguments are of the same type. - - A similar alternative is to have one of the required arguments be a -bit mask, with a bit for each possible purpose for which an optional -argument might be supplied. You would test the bits in a predefined -sequence; if the bit is set, fetch the value of the next argument, -otherwise use a default value. - - A required argument can be used as a pattern to specify both the -number and types of the optional arguments. The format string argument -to `printf' is one example of this (*note Formatted Output Functions::). - - Another possibility is to pass an "end marker" value as the last -optional argument. For example, for a function that manipulates an -arbitrary number of pointer arguments, a null pointer might indicate the -end of the argument list. (This assumes that a null pointer isn't -otherwise meaningful to the function.) The `execl' function works in -just this way; see *Note Executing a File::. - - -File: libc.info, Node: Calling Variadics, Next: Argument Macros, Prev: How Many Arguments, Up: How Variadic - -Calling Variadic Functions -.......................... - - You don't have to do anything special to call a variadic function. -Just put the arguments (required arguments, followed by optional ones) -inside parentheses, separated by commas, as usual. But you must declare -the function with a prototype and know how the argument values are -converted. - - In principle, functions that are _defined_ to be variadic must also -be _declared_ to be variadic using a function prototype whenever you -call them. (*Note Variadic Prototypes::, for how.) This is because -some C compilers use a different calling convention to pass the same set -of argument values to a function depending on whether that function -takes variable arguments or fixed arguments. - - In practice, the GNU C compiler always passes a given set of argument -types in the same way regardless of whether they are optional or -required. So, as long as the argument types are self-promoting, you can -safely omit declaring them. Usually it is a good idea to declare the -argument types for variadic functions, and indeed for all functions. -But there are a few functions which it is extremely convenient not to -have to declare as variadic--for example, `open' and `printf'. - - Since the prototype doesn't specify types for optional arguments, in -a call to a variadic function the "default argument promotions" are -performed on the optional argument values. This means the objects of -type `char' or `short int' (whether signed or not) are promoted to -either `int' or `unsigned int', as appropriate; and that objects of -type `float' are promoted to type `double'. So, if the caller passes a -`char' as an optional argument, it is promoted to an `int', and the -function can access it with `va_arg (AP, int)'. - - Conversion of the required arguments is controlled by the function -prototype in the usual way: the argument expression is converted to the -declared argument type as if it were being assigned to a variable of -that type. - - -File: libc.info, Node: Argument Macros, Next: Old Varargs, Prev: Calling Variadics, Up: How Variadic - -Argument Access Macros -...................... - - Here are descriptions of the macros used to retrieve variable -arguments.

TYPE must be a self-promoting type (not `char' or - `short int' or `float') that matches the type of the actual - argument. - - - Macro: void va_end (va_list AP) - This ends the use of AP. After a `va_end' call, further `va_arg' - calls with the same AP may not work. You should invoke `va_end' - before returning from the function in which `va_start' was invoked - with the same AP argument. - - In the GNU C library, `va_end' does nothing, and you need not ever - use it except for reasons of portability. - - - Sometimes it is necessary to parse the list of parameters more than -once or one wants to remember a certain position in the parameter list. -To do this, one will have to make a copy of the current value of the -argument. But `va_list' is an opaque type and one cannot necessarily -assign the value of one variable of type `va_list' to another variable -of the same type. - - - Macro: void __va_copy (va_list DEST, va_list SRC) - The `__va_copy' macro allows copying of objects of type `va_list' - even if this is not an integral type.

There is -no difference in how you call a variadic function; see *Note Calling -Variadics::. The only difference is in how you define them. First of -all, you must use old-style non-prototype syntax, like this: - - tree - build (va_alist) - va_dcl - { - - Secondly, you must give `va_start' only one argument, like this: - - va_list p; - va_start (p); - - These are the special macros used for defining old-style variadic -functions: - - - Macro: va_alist - This macro stands for the argument name list required in a variadic - function. - - - Macro: va_dcl - This macro declares the implicit argument or arguments for a - variadic function. - - - Macro: void va_start (va_list AP) - This macro, as defined in `varargs.h', initializes the argument - pointer variable AP to point to the first argument of the current - function. - - The other argument macros, `va_arg' and `va_end', are the same in -`varargs.h' as in `stdarg.h'; see *Note Argument Macros::, for details. - - It does not work to include both `varargs.h' and `stdarg.h' in the -same compilation; they define `va_start' in conflicting ways. - - -File: libc.info, Node: Null Pointer Constant, Next: Important Data Types, Prev: Variadic Functions, Up: Language Features - -Null Pointer Constant -===================== - - The null pointer constant is guaranteed not to point to any real -object.

The result of the `sizeof' operator is of this type, and - functions such as `malloc' (*note Unconstrained Allocation::) and - `memcpy' (*note Copying and Concatenation::) accept arguments of - this type to specify object sizes. - - *Usage Note:* `size_t' is the preferred way to declare any - arguments or variables that hold the size of an object. - - In the GNU system `size_t' is equivalent to either `unsigned int' or -`unsigned long int'. These types have identical properties on the GNU -system and, for most purposes, you can use them interchangeably. -However, they are distinct as data types, which makes a difference in -certain contexts. - - For example, when you specify the type of a function argument in a -function prototype, it makes a difference which one you use. If the -system header files declare `malloc' with an argument of type `size_t' -and you declare `malloc' with an argument of type `unsigned int', you -will get a compilation error if `size_t' happens to be `unsigned long -int' on your system. To avoid any possibility of error, when a -function argument or value is supposed to have type `size_t', never -declare its type in any other way. - - *Compatibility Note:* Implementations of C before the advent of -ISO C generally used `unsigned int' for representing object sizes and -`int' for pointer subtraction results.

This is a constant for a particular representation. - - * The "exponent" to which the base is raised. The upper and lower - bounds of the exponent value are constants for a particular - representation. - - Sometimes, in the actual bits representing the floating point - number, the exponent is "biased" by adding a constant to it, to - make it always be represented as an unsigned quantity. This is - only important if you have some reason to pick apart the bit - fields making up the floating point number by hand, which is - something for which the GNU library provides no support. So this - is ignored in the discussion that follows. - - * The "mantissa" or "significand" is an unsigned integer which is a - part of each floating point number. - - * The "precision" of the mantissa. If the base of the representation - is B, then the precision is the number of base-B digits in the - mantissa. This is a constant for a particular representation. - - Many floating point representations have an implicit "hidden bit" - in the mantissa. This is a bit which is present virtually in the - mantissa, but not stored in memory because its value is always 1 - in a normalized number. The precision figure (see above) includes - any hidden bits. - - Again, the GNU library provides no facilities for dealing with such - low-level aspects of the representation. - - The mantissa of a floating point number represents an implicit -fraction whose denominator is the base raised to the power of the -precision. Since the largest representable mantissa is one less than -this denominator, the value of the fraction is always strictly less -than `1'. The mathematical value of a floating point number is then -the product of this fraction, the sign, and the base raised to the -exponent. - - We say that the floating point number is "normalized" if the -fraction is at least `1/B', where B is the base. In other words, the -mantissa would be too large to fit if it were multiplied by the base. -Non-normalized numbers are sometimes called "denormal"; they contain -less precision than the representation normally can hold. - - If the number is not normalized, then you can subtract `1' from the -exponent while multiplying the mantissa by the base, and get another -floating point number with the same value. "Normalization" consists of -doing this repeatedly until the number is normalized. Two distinct -normalized floating point numbers cannot be equal in value. - - (There is an exception to this rule: if the mantissa is zero, it is -considered normalized. Another exception happens on certain machines -where the exponent is as small as the representation can hold. Then it -is impossible to subtract `1' from the exponent, so a number may be -normalized even if its fraction is less than `1/B'.) - - -File: libc.info, Node: Floating Point Parameters, Next: IEEE Floating Point, Prev: Floating Point Concepts, Up: Floating Type Macros - -Floating Point Parameters -......................... - - These macro definitions can be accessed by including the header file -`float.h' in your program. - - Macro names starting with `FLT_' refer to the `float' type, while -names beginning with `DBL_' refer to the `double' type and names -beginning with `LDBL_' refer to the `long double' type. (If GCC does -not support `long double' as a distinct data type on a target machine -then the values for the `LDBL_' constants are equal to the -corresponding constants for the `double' type.) - - Of these macros, only `FLT_RADIX' is guaranteed to be a constant -expression. The other macros listed here cannot be reliably used in -places that require constant expressions, such as `#if' preprocessing -directives or in the dimensions of static arrays. - - Although the ISO C standard specifies minimum and maximum values for -most of these parameters, the GNU C implementation uses whatever values -describe the floating point representation of the target machine.

This file answers common questions -and describes problems you may experience with compilation and -installation. It is updated more frequently than this manual. - - Features can be added to GNU Libc via "add-on" bundles. These are -separate tar files, which you unpack into the top level of the source -tree. Then you give `configure' the `--enable-add-ons' option to -activate them, and they will be compiled into the library. As of the -2.2 release, one important component of glibc is distributed as -"official" add-ons: the linuxthreads add-on. Unless you are doing an -unusual installation, you should get this. - - Support for POSIX threads is maintained by someone else, so it's in a -separate package. It is only available for GNU/Linux systems, but this -will change in the future. Get it from the same place you got the main -bundle; the file is `glibc-linuxthreads-VERSION.tar.gz'. - - You will need recent versions of several GNU tools: definitely GCC -and GNU Make, and possibly others. *Note Tools for Compilation::, -below. - -* Menu: - -* Configuring and compiling:: How to compile and test GNU libc. -* Running make install:: How to install it once you've got it - compiled. -* Tools for Compilation:: You'll need these first. -* Supported Configurations:: What it runs on, what it doesn't. -* Linux:: Specific advice for GNU/Linux systems. -* Reporting Bugs:: So they'll get fixed. - - -File: libc.info, Node: Configuring and compiling, Next: Running make install, Up: Installation - -Configuring and compiling GNU Libc -================================== - - GNU libc can be compiled in the source directory, but we strongly -advise building it in a separate build directory. For example, if you -have unpacked the glibc sources in `/src/gnu/glibc-2.3', create a -directory `/src/gnu/glibc-build' to put the object files in. This -allows removing the whole build directory in case an error occurs, -which is the safest way to get a fresh start and should always be done. - - From your object directory, run the shell script `configure' located -at the top level of the source tree. In the scenario above, you'd type - - $ ../glibc-2.3/configure ARGS... - - Please note that even if you're building in a separate build -directory, the compilation needs to modify a few files in the source -directory, especially some files in the manual subdirectory. - -`configure' takes many options, but you can get away with knowing only -two: `--prefix' and `--enable-add-ons'. The `--prefix' option tells -`configure' where you want glibc installed. This defaults to -`/usr/local'. The `--enable-add-ons' option tells `configure' to use -all the add-on bundles it finds in the source directory. Since -important functionality is provided in add-ons, you should always -specify this option. - - It may also be useful to set the CC and CFLAGS variables in the -environment when running `configure'. CC selects the C compiler that -will be used, and CFLAGS sets optimization options for the compiler. - - The following list describes all of the available options for -`configure': - -`--prefix=DIRECTORY' - Install machine-independent data files in subdirectories of - `DIRECTORY'. The default is to install in `/usr/local'. - -`--exec-prefix=DIRECTORY' - Install the library and other machine-dependent files in - subdirectories of `DIRECTORY'. The default is to the `--prefix' - directory if that option is specified, or `/usr/local' otherwise. - -`--with-headers=DIRECTORY' - Look for kernel header files in DIRECTORY, not `/usr/include'. - Glibc needs information from the kernel's private header files. - Glibc will normally look in `/usr/include' for them, but if you - specify this option, it will look in DIRECTORY instead. - - This option is primarily of use on a system where the headers in - `/usr/include' come from an older version of glibc. Conflicts can - occasionally happen in this case. Note that Linux libc5 qualifies - as an older version of glibc. You can also use this option if you - want to compile glibc with a newer set of kernel headers than the - ones found in `/usr/include'. - -`--enable-add-ons[=LIST]' - Enable add-on packages in your source tree. If this option is - specified with no list, it enables all the add-on packages it - finds. If you do not wish to use some add-on packages that you - have present in your source tree, give this option a list of the - add-ons that you _do_ want used, like this: - `--enable-add-ons=linuxthreads' - -`--enable-kernel=VERSION' - This option is currently only useful on GNU/Linux systems. The - VERSION parameter should have the form X.Y.Z and describes the - smallest version of the Linux kernel the generated library is - expected to support. The higher the VERSION number is, the less - compatibility code is added, and the faster the code gets. - -`--with-binutils=DIRECTORY' - Use the binutils (assembler and linker) in `DIRECTORY', not the - ones the C compiler would default to. You can use this option if - the default binutils on your system cannot deal with all the - constructs in the GNU C library. In that case, `configure' will - detect the problem and suppress these constructs, so that the - library will still be usable, but functionality may be lost--for - example, you can't build a shared libc with old binutils. - -`--without-fp' - Use this option if your computer lacks hardware floating-point - support and your operating system does not emulate an FPU. - - these - -`--disable-shared' - Don't build shared libraries even if it is possible. Not all - systems support shared libraries; you need ELF support and - (currently) the GNU linker. - -`--disable-profile' - Don't build libraries with profiling information. You may want to - use this option if you don't plan to do profiling. - -`--enable-omitfp' - Use maximum optimization for the normal (static and shared) - libraries, and compile separate static libraries with debugging - information and no optimization. We recommend not doing this. - The extra optimization doesn't gain you much, it may provoke - compiler bugs, and you won't be able to trace bugs through the C - library. - -`--disable-versioning' - Don't compile the shared libraries with symbol version information. - Doing this will make the resulting library incompatible with old - binaries, so it's not recommended. - -`--enable-static-nss' - Compile static versions of the NSS (Name Service Switch) libraries. - This is not recommended because it defeats the purpose of NSS; a - program linked statically with the NSS libraries cannot be - dynamically reconfigured to use a different name database. - -`--without-tls' - By default the C library is built with support for thread-local - storage if the used tools support it. By using `--without-tls' - this can be prevented though there generally is no reason since it - creates compatibility problems. - -`--build=BUILD-SYSTEM' -`--host=HOST-SYSTEM' - These options are for cross-compiling. If you specify both - options and BUILD-SYSTEM is different from HOST-SYSTEM, `configure' - will prepare to cross-compile glibc from BUILD-SYSTEM to be used - on HOST-SYSTEM. You'll probably need the `--with-headers' option - too, and you may have to override CONFIGURE's selection of the - compiler and/or binutils. - - If you only specify `--host', `configure' will prepare for a - native compile but use what you specify instead of guessing what - your system is. This is most useful to change the CPU submodel. - For example, if `configure' guesses your machine as - `i586-pc-linux-gnu' but you want to compile a library for 386es, - give `--host=i386-pc-linux-gnu' or just `--host=i386-linux' and add - the appropriate compiler flags (`-mcpu=i386' will do the trick) to - CFLAGS. - - If you specify just `--build', `configure' will get confused. - - To build the library and related programs, type `make'. This will -produce a lot of output, some of which may look like errors from `make' -but isn't. Look for error messages from `make' containing `***'. -Those indicate that something is seriously wrong. - - The compilation process can take several hours. Expect at least two -hours for the default configuration on i586 for GNU/Linux. For Hurd, -times are much longer. Some complex modules may take a very long time -to compile, as much as several minutes on slower machines. Do not -panic if the compiler appears to hang. - - If you want to run a parallel make, simply pass the `-j' option with -an appropriate numeric parameter to `make'. You need a recent GNU -`make' version, though. - - To build and run test programs which exercise some of the library -facilities, type `make check'. If it does not complete successfully, -do not use the built library, and report a bug after verifying that the -problem is not already known. *Note Reporting Bugs::, for instructions -on reporting bugs. Note that some of the tests assume they are not -being run by `root'. We recommend you compile and test glibc as an -unprivileged user. - - Before reporting bugs make sure there is no problem with your system. -The tests (and later installation) use some pre-existing files of the -system such as `/etc/passwd', `/etc/nsswitch.conf' and others. These -files must all contain correct and sensible content. - - To format the `GNU C Library Reference Manual' for printing, type -`make dvi'. You need a working TeX installation to do this. The -distribution already includes the on-line formatted version of the -manual, as Info files. You can regenerate those with `make info', but -it shouldn't be necessary. - - The library has a number of special-purpose configuration parameters -which you can find in `Makeconfig'. These can be overwritten with the -file `configparms'. To change them, create a `configparms' in your -build directory and add values as appropriate for your system. The -file is included and parsed by `make' and has to follow the conventions -for makefiles. - - It is easy to configure the GNU C library for cross-compilation by -setting a few variables in `configparms'. Set `CC' to the -cross-compiler for the target you configured the library for; it is -important to use this same `CC' value when running `configure', like -this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler -to use for programs run on the build system as part of compiling the -library. You may need to set `AR' and `RANLIB' to cross-compiling -versions of `ar' and `ranlib' if the native tools are not configured to -work with object files for the target you configured for. - - -File: libc.info, Node: Running make install, Next: Tools for Compilation, Prev: Configuring and compiling, Up: Installation - -Installing the C Library -======================== - - To install the library and its header files, and the Info files of -the manual, type `env LANGUAGE=C LC_ALL=C make install'. This will -build things, if necessary, before installing them; however, you should -still compile everything first. If you are installing glibc as your -primary C library, we recommend that you shut the system down to -single-user mode first, and reboot afterward. This minimizes the risk -of breaking things when the library changes out from underneath. - - If you're upgrading from Linux libc5 or some other C library, you -need to replace the `/usr/include' with a fresh directory before -installing it. The new `/usr/include' should contain the Linux -headers, but nothing else. - - You must first build the library (`make'), optionally check it -(`make check'), switch the include directories and then install (`make -install'). The steps must be done in this order. Not moving the -directory before install will result in an unusable mixture of header -files from both libraries, but configuring, building, and checking the -library requires the ability to compile and run programs against the old -library. - - If you are upgrading from a previous installation of glibc 2.0 or -2.1, `make install' will do the entire job. You do not need to remove -the old includes - if you want to do so anyway you must then follow the -order given above. - - You may also need to reconfigure GCC to work with the new library. -The easiest way to do that is to figure out the compiler switches to -make it work again (`-Wl,--dynamic-linker=/lib/ld-linux.so.2' should -work on GNU/Linux systems) and use them to recompile gcc. You can also -edit the specs file (`/usr/lib/gcc-lib/TARGET/VERSION/specs'), but that -is a bit of a black art. - - You can install glibc somewhere other than where you configured it -to go by setting the `install_root' variable on the command line for -`make install'. The value of this variable is prepended to all the -paths for installation. This is useful when setting up a chroot -environment or preparing a binary distribution. The directory should be -specified with an absolute file name. - - Glibc 2.2 includes a daemon called `nscd', which you may or may not -want to run. `nscd' caches name service lookups; it can dramatically -improve performance with NIS+, and may help with DNS as well. - - One auxiliary program, `/usr/libexec/pt_chown', is installed setuid -`root'. This program is invoked by the `grantpt' function; it sets the -permissions on a pseudoterminal so it can be used by the calling -process. This means programs like `xterm' and `screen' do not have to -be setuid to get a pty. (There may be other reasons why they need -privileges.) If you are using a 2.1 or newer Linux kernel with the -`devptsfs' or `devfs' filesystems providing pty slaves, you don't need -this program; otherwise you do. The source for `pt_chown' is in -`login/programs/pt_chown.c'. - - After installation you might want to configure the timezone and -locale installation of your system. The GNU C library comes with a -locale database which gets configured with `localedef'. For example, to -set up a German locale with name `de_DE', simply issue the command -`localedef -i de_DE -f ISO-8859-1 de_DE'. To configure all locales -that are supported by glibc, you can issue from your build directory the -command `make localedata/install-locales'. - - To configure the locally used timezone, set the `TZ' environment -variable. The script `tzselect' helps you to select the right value. -As an example, for Germany, `tzselect' would tell you to use -`TZ='Europe/Berlin''. For a system wide installation (the given paths -are for an installation with `--prefix=/usr'), link the timezone file -which is in `/usr/share/zoneinfo' to the file `/etc/localtime'. For -Germany, you might execute `ln -s /usr/share/zoneinfo/Europe/Berlin -/etc/localtime'. - - -File: libc.info, Node: Tools for Compilation, Next: Supported Configurations, Prev: Running make install, Up: Installation - -Recommended Tools for Compilation -================================= - - We recommend installing the following GNU tools before attempting to -build the GNU C library: - - * GNU `make' 3.79 or newer - - You need the latest version of GNU `make'. Modifying the GNU C - Library to work with other `make' programs would be so difficult - that we recommend you port GNU `make' instead. *Really.* We - recommend GNU `make' version 3.79. All earlier versions have - severe bugs or lack features. - - * GCC 3.2 or newer - - The GNU C library can only be compiled with the GNU C compiler - family. As of the 2.3 release, GCC 3.2 or higher is required. As - of this writing, GCC 3.2 is the compiler we advise to use. - - You can use whatever compiler you like to compile programs that - use GNU libc, but be aware that both GCC 2.7 and 2.8 have bugs in - their floating-point support that may be triggered by the math - library. - - Check the FAQ for any special compiler issues on particular - platforms. - - * GNU `binutils' 2.13 or later - - You must use GNU `binutils' (as and ld) to build the GNU C library. - No other assembler and linker has the necessary functionality in - the moment. - - * GNU `texinfo' 3.12f - - To correctly translate and install the Texinfo documentation you - need this version of the `texinfo' package. Earlier versions do - not understand all the tags used in the document, and the - installation mechanism for the info files is not present or works - differently. - - * GNU `awk' 3.0, or some other POSIX awk - - `Awk' is used in several places to generate files. The scripts - should work with any POSIX-compliant `awk' implementation; `gawk' - 3.0 and `mawk' 1.3 are known to work. - - * Perl 5 - - Perl is not required, but it is used if present to test the - installation. We may decide to use it elsewhere in the future. - - * GNU `sed' 3.02 or newer - - `Sed' is used in several places to generate files. Most scripts - work with any version of `sed'. The known exception is the script - `po2test.sed' in the `intl' subdirectory which is used to generate - `msgs.h' for the test suite. This script works correctly only - with GNU `sed' 3.02. If you like to run the test suite, you - should definitely upgrade `sed'. - - -If you change any of the `configure.in' files you will also need - - * GNU `autoconf' 2.12 or higher - -and if you change any of the message translation files you will need - - * GNU `gettext' 0.10.36 or later - -You may also need these packages if you upgrade your source tree using -patches, although we try to avoid this. - - -File: libc.info, Node: Supported Configurations, Next: Linux, Prev: Tools for Compilation, Up: Installation - -Supported Configurations -======================== - - The GNU C Library currently supports configurations that match the -following patterns: - - alpha*-*-linux - arm-*-linux - cris-*-linux - hppa-*-linux - iX86-*-gnu - iX86-*-linux - ia64-*-linux - m68k-*-linux - mips*-*-linux - powerpc-*-linux - s390-*-linux - s390x-*-linux - sparc-*-linux - sparc64-*-linux - - Former releases of this library (version 2.1 and/or 2.0) used to run -on the following configurations: - - arm-*-linuxaout - arm-*-none - - Very early releases (version 1.09.1 and perhaps earlier versions) -used to run on the following configurations: - - alpha-dec-osf1 - alpha-*-linuxecoff - iX86-*-bsd4.3 - iX86-*-isc2.2 - iX86-*-isc3.N - iX86-*-sco3.2 - iX86-*-sco3.2v4 - iX86-*-sysv - iX86-*-sysv4 - iX86-force_cpu386-none - iX86-sequent-bsd - i960-nindy960-none - m68k-hp-bsd4.3 - m68k-mvme135-none - m68k-mvme136-none - m68k-sony-newsos3 - m68k-sony-newsos4 - m68k-sun-sunos4.N - mips-dec-ultrix4.N - mips-sgi-irix4.N - sparc-sun-solaris2.N - sparc-sun-sunos4.N - - Since no one has volunteered to test and fix these configurations, -they are not supported at the moment. They probably don't compile; -they definitely don't work anymore. Porting the library is not hard. -If you are interested in doing a port, please contact the glibc -maintainers by sending electronic mail to . - - Valid cases of `iX86' include `i386', `i486', `i586', and `i686'. -All of those configurations produce a library that can run on this -processor and newer processors. The GCC compiler by default generates -code that's optimized for the machine it's configured for and will use -the instructions available on that machine. For example if your GCC is -configured for `i686', gcc will optimize for `i686' and might issue -some `i686' specific instructions. To generate code for other models, -you have to configure for that model and give GCC the appropriate -`-march=' and `-mcpu=' compiler switches via CFLAGS. - - -File: libc.info, Node: Linux, Next: Reporting Bugs, Prev: Supported Configurations, Up: Installation - -Specific advice for GNU/Linux systems -===================================== - - If you are installing GNU libc on a GNU/Linux system, you need to -have the header files from a 2.2 or newer kernel around for reference. -For some architectures, like ia64, sh and hppa, you need at least -headers from kernel 2.3.99 (sh and hppa) or 2.4.0 (ia64). You do not -need to use that kernel, just have its headers where glibc can access -at them. The easiest way to do this is to unpack it in a directory -such as `/usr/src/linux-2.2.1'. In that directory, run `make config' -and accept all the defaults. Then run `make include/linux/version.h'. -Finally, configure glibc with the option -`--with-headers=/usr/src/linux-2.2.1/include'. Use the most recent -kernel you can get your hands on. - - An alternate tactic is to unpack the 2.2 kernel and run `make -config' as above; then, rename or delete `/usr/include', create a new -`/usr/include', and make symbolic links of `/usr/include/linux' and -`/usr/include/asm' into the kernel sources. You can then configure -glibc with no special options. This tactic is recommended if you are -upgrading from libc5, since you need to get rid of the old header files -anyway. - - After installing GNU libc, you may need to remove or rename -`/usr/include/linux' and `/usr/include/asm', and replace them with -copies of `include/linux' and `include/asm-$ARCHITECTURE' taken from -the Linux source package which supplied kernel headers for building the -library. ARCHITECTURE will be the machine architecture for which the -library was built, such as `i386' or `alpha'. You do not need to do -this if you did not specify an alternate kernel header source using -`--with-headers'. The intent here is that these directories should be -copies of, *not* symlinks to, the kernel headers used to build the -library. - - Note that `/usr/include/net' and `/usr/include/scsi' should *not* be -symlinks into the kernel sources. GNU libc provides its own versions -of these files. - - GNU/Linux expects some components of the libc installation to be in -`/lib' and some in `/usr/lib'. This is handled automatically if you -configure glibc with `--prefix=/usr'. If you set some other prefix or -allow it to default to `/usr/local', then all the components are -installed there. - - If you are upgrading from libc5, you need to recompile every shared -library on your system against the new library for the sake of new code, -but keep the old libraries around for old binaries to use. This is -complicated and difficult. Consult the Glibc2 HOWTO at - for details. - - You cannot use `nscd' with 2.0 kernels, due to bugs in the -kernel-side thread support. `nscd' happens to hit these bugs -particularly hard, but you might have problems with any threaded -program. - - -File: libc.info, Node: Reporting Bugs, Prev: Linux, Up: Installation - -Reporting Bugs -============== - - There are probably bugs in the GNU C library. There are certainly -errors and omissions in this manual. If you report them, they will get -fixed. If you don't, no one will ever know about them and they will -remain unfixed for all eternity, if not longer. - - It is a good idea to verify that the problem has not already been -reported. Bugs are documented in two places: The file `BUGS' describes -a number of well known bugs and the bug tracking system has a WWW -interface at . The -WWW interface gives you access to open and closed reports. A closed -report normally includes a patch or a hint on solving the problem. - - To report a bug, first you must find it. With any luck, this will -be the hard part. Once you've found a bug, make sure it's really a -bug. A good way to do this is to see if the GNU C library behaves the -same way some other C library does. If so, probably you are wrong and -the libraries are right (but not necessarily). If not, one of the -libraries is probably wrong. It might not be the GNU library. Many -historical Unix C libraries permit things that we don't, such as -closing a file twice. - - If you think you have found some way in which the GNU C library does -not conform to the ISO and POSIX standards (*note Standards and -Portability::), that is definitely a bug. Report it! - - Once you're sure you've found a bug, try to narrow it down to the -smallest test case that reproduces the problem. In the case of a C -library, you really only need to narrow it down to one library function -call, if possible. This should not be too difficult. - - The final step when you have a simple test case is to report the bug. -Do this using the `glibcbug' script. It is installed with libc, or if -you haven't installed it, will be in your build directory. Send your -test case, the results you got, the results you expected, and what you -think the problem might be (if you've thought of anything). `glibcbug' -will insert the configuration information we need to see, and ship the -report off to . Don't send a message there directly; it -is fed to a program that expects mail to be formatted in a particular -way. Use the script. - - If you are not sure how a function should behave, and this manual -doesn't tell you, that's a bug in the manual. Report that too! If the -function's behavior disagrees with the manual, then either the library -or the manual has a bug, so report the disagreement. If you find any -errors or omissions in this manual, please report them to the Internet -address .

The makefiles are -very complex, and you probably don't want to try to understand them. -But what they do is fairly straightforward, and only requires that you -define a few variables in the right places. - - The library sources are divided into subdirectories, grouped by -topic. - - The `string' subdirectory has all the string-manipulation functions, -`math' has all the mathematical functions, etc. - - Each subdirectory contains a simple makefile, called `Makefile', -which defines a few `make' variables and then includes the global -makefile `Rules' with a line like: - - include ../Rules - -The basic variables that a subdirectory makefile defines are: - -`subdir' - The name of the subdirectory, for example `stdio'. This variable - *must* be defined. - -`headers' - The names of the header files in this section of the library, such - as `stdio.h'. - -`routines' -`aux' - The names of the modules (source files) in this section of the - library. These should be simple names, such as `strlen' (rather - than complete file names, such as `strlen.c'). Use `routines' for - modules that define functions in the library, and `aux' for - auxiliary modules containing things like data definitions. But the - values of `routines' and `aux' are just concatenated, so there - really is no practical difference. - -`tests' - The names of test programs for this section of the library. These - should be simple names, such as `tester' (rather than complete file - names, such as `tester.c'). `make tests' will build and run all - the test programs. If a test program needs input, put the test - data in a file called `TEST-PROGRAM.input'; it will be given to - the test program on its standard input. If a test program wants - to be run with arguments, put the arguments (all on a single line) - in a file called `TEST-PROGRAM.args'. Test programs should exit - with zero status when the test passes, and nonzero status when the - test indicates a bug in the library or error in building. - -`others' - The names of "other" programs associated with this section of the - library. These are programs which are not tests per se, but are - other small programs included with the library. They are built by - `make others'. - -`install-lib' -`install-data' -`install' - Files to be installed by `make install'. Files listed in - `install-lib' are installed in the directory specified by `libdir' - in `configparms' or `Makeconfig' (*note Installation::). Files - listed in `install-data' are installed in the directory specified - by `datadir' in `configparms' or `Makeconfig'. Files listed in - `install' are installed in the directory specified by `bindir' in - `configparms' or `Makeconfig'. - -`distribute' - Other files from this subdirectory which should be put into a - distribution tar file. You need not list here the makefile itself - or the source and header files listed in the other standard - variables. Only define `distribute' if there are files used in an - unusual way that should go into the distribution. - -`generated' - Files which are generated by `Makefile' in this subdirectory. - These files will be removed by `make clean', and they will never - go into a distribution. - -`extra-objs' - Extra object files which are built by `Makefile' in this - subdirectory. This should be a list of file names like `foo.o'; - the files will actually be found in whatever directory object - files are being built in. These files will be removed by - `make clean'. This variable is used for secondary object files - needed to build `others' or `tests'. - - -File: libc.info, Node: Porting, Prev: Source Layout, Up: Maintenance - -Porting the GNU C Library -========================= - - The GNU C library is written to be easily portable to a variety of -machines and operating systems. Machine- and operating system-dependent -functions are well separated to make it easy to add implementations for -new machines or operating systems. This section describes the layout of -the library source tree and explains the mechanisms used to select -machine-dependent code to use. - - All the machine-dependent and operating system-dependent files in the -library are in the subdirectory `sysdeps' under the top-level library -source directory. This directory contains a hierarchy of -subdirectories (*note Hierarchy Conventions::). - - Each subdirectory of `sysdeps' contains source files for a -particular machine or operating system, or for a class of machine or -operating system (for example, systems by a particular vendor, or all -machines that use IEEE 754 floating-point format). A configuration -specifies an ordered list of these subdirectories. Each subdirectory -implicitly appends its parent directory to the list. For example, -specifying the list `unix/bsd/vax' is equivalent to specifying the list -`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it -implies other subdirectories which are not directly above it in the -directory hierarchy. If the file `Implies' exists in a subdirectory, -it lists other subdirectories of `sysdeps' which are appended to the -list, appearing after the subdirectory containing the `Implies' file. -Lines in an `Implies' file that begin with a `#' character are ignored -as comments. For example, `unix/bsd/Implies' contains: - # BSD has Internet-related things. - unix/inet - -and `unix/Implies' contains: - posix - -So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'. - - `sysdeps' has a "special" subdirectory called `generic'. It is -always implicitly appended to the list of subdirectories, so you -needn't put it in an `Implies' file, and you should not create any -subdirectories under it intended to be new specific categories. -`generic' serves two purposes. First, the makefiles do not bother to -look for a system-dependent version of a file that's not in `generic'. -This means that any system-dependent source file must have an analogue -in `generic', even if the routines defined by that file are not -implemented on other platforms. Second. the `generic' version of a -system-dependent file is used if the makefiles do not find a version -specific to the system you're compiling for. - - If it is possible to implement the routines in a `generic' file in -machine-independent C, using only other machine-independent functions in -the C library, then you should do so. Otherwise, make them stubs. A -"stub" function is a function which cannot be implemented on a -particular machine or operating system. Stub functions always return an -error, and set `errno' to `ENOSYS' (Function not implemented). *Note -Error Reporting::. If you define a stub function, you must place the -statement `stub_warning(FUNCTION)', where FUNCTION is the name of your -function, after its definition; also, you must include the file -`' into your file. This causes the function to be listed -in the installed `', and makes GNU ld warn when the -function is used. - - Some rare functions are only useful on specific systems and aren't -defined at all on others; these do not appear anywhere in the -system-independent source code or makefiles (including the `generic' -directory), only in the system-dependent `Makefile' in the specific -system's subdirectory. - - If you come across a file that is in one of the main source -directories (`string', `stdio', etc.), and you want to write a machine- -or operating system-dependent version of it, move the file into -`sysdeps/generic' and write your new implementation in the appropriate -system-specific subdirectory. Note that if a file is to be -system-dependent, it *must not* appear in one of the main source -directories. - - There are a few special files that may exist in each subdirectory of -`sysdeps': - -`Makefile' - A makefile for this machine or operating system, or class of - machine or operating system. This file is included by the library - makefile `Makerules', which is used by the top-level makefile and - the subdirectory makefiles. It can change the variables set in the - including makefile or add new rules. It can use GNU `make' - conditional directives based on the variable `subdir' (see above) - to select different sets of variables and rules for different - sections of the library. It can also set the `make' variable - `sysdep-routines', to specify extra modules to be included in the - library. You should use `sysdep-routines' rather than adding - modules to `routines' because the latter is used in determining - what to distribute for each subdirectory of the main source tree. - - Each makefile in a subdirectory in the ordered list of - subdirectories to be searched is included in order. Since several - system-dependent makefiles may be included, each should append to - `sysdep-routines' rather than simply setting it: - - sysdep-routines := $(sysdep-routines) foo bar - -`Subdirs' - This file contains the names of new whole subdirectories under the - top-level library source tree that should be included for this - system. These subdirectories are treated just like the - system-independent subdirectories in the library source tree, such - as `stdio' and `math'. - - Use this when there are completely new sets of functions and header - files that should go into the library for the system this - subdirectory of `sysdeps' implements. For example, - `sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory - contains various network-oriented operations which only make sense - to put in the library on systems that support the Internet. - -`Dist' - This file contains the names of files (relative to the - subdirectory of `sysdeps' in which it appears) which should be - included in the distribution. List any new files used by rules in - the `Makefile' in the same directory, or header files used by the - source files in that directory. You don't need to list files that - are implementations (either C or assembly source) of routines - whose names are given in the machine-independent makefiles in the - main source tree. - -`configure' - This file is a shell script fragment to be run at configuration - time. The top-level `configure' script uses the shell `.' command - to read the `configure' file in each system-dependent directory - chosen, in order. The `configure' files are often generated from - `configure.in' files using Autoconf. - - A system-dependent `configure' script will usually add things to - the shell variables `DEFS' and `config_vars'; see the top-level - `configure' script for details. The script can check for - `--with-PACKAGE' options that were passed to the top-level - `configure'. For an option `--with-PACKAGE=VALUE' `configure' - sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE - converted to underscores) to VALUE; if the option is just - `--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to - `yes'. - -`configure.in' - This file is an Autoconf input fragment to be processed into the - file `configure' in this subdirectory. *Note Introduction: - (autoconf.info)Introduction, for a description of Autoconf. You - should write either `configure' or `configure.in', but not both. - The first line of `configure.in' should invoke the `m4' macro - `GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for - Autoconf macros which are used by the top-level `configure' - script; without this, those macros might be invoked again - unnecessarily by Autoconf. - - That is the general system for how system-dependencies are isolated. - -* Menu: - -* Hierarchy Conventions:: The layout of the `sysdeps' hierarchy. -* Porting to Unix:: Porting the library to an average - Unix-like system. - - -File: libc.info, Node: Hierarchy Conventions, Next: Porting to Unix, Up: Porting - -Layout of the `sysdeps' Directory Hierarchy -------------------------------------------- - - A GNU configuration name has three parts: the CPU type, the -manufacturer's name, and the operating system. `configure' uses these -to pick the list of system-dependent directories to look for. If the -`--nfp' option is _not_ passed to `configure', the directory -`MACHINE/fpu' is also used. The operating system often has a "base -operating system"; for example, if the operating system is `Linux', the -base operating system is `unix/sysv'. The algorithm used to pick the -list of directories is simple: `configure' makes a list of the base -operating system, manufacturer, CPU type, and operating system, in that -order. It then concatenates all these together with slashes in -between, to produce a directory name; for example, the configuration -`i686-linux-gnu' results in `unix/sysv/linux/i386/i686'. `configure' -then tries removing each element of the list in turn, so -`unix/sysv/linux' and `unix/sysv' are also tried, among others. Since -the precise version number of the operating system is often not -important, and it would be very inconvenient, for example, to have -identical `irix6.2' and `irix6.3' directories, `configure' tries -successively less specific operating system names by removing trailing -suffixes starting with a period. - - As an example, here is the complete list of directories that would be -tried for the configuration `i686-linux-gnu' (with the `crypt' and -`linuxthreads' add-on): - - sysdeps/i386/elf - crypt/sysdeps/unix - linuxthreads/sysdeps/unix/sysv/linux - linuxthreads/sysdeps/pthread - linuxthreads/sysdeps/unix/sysv - linuxthreads/sysdeps/unix - linuxthreads/sysdeps/i386/i686 - linuxthreads/sysdeps/i386 - linuxthreads/sysdeps/pthread/no-cmpxchg - sysdeps/unix/sysv/linux/i386 - sysdeps/unix/sysv/linux - sysdeps/gnu - sysdeps/unix/common - sysdeps/unix/mman - sysdeps/unix/inet - sysdeps/unix/sysv/i386/i686 - sysdeps/unix/sysv/i386 - sysdeps/unix/sysv - sysdeps/unix/i386 - sysdeps/unix - sysdeps/posix - sysdeps/i386/i686 - sysdeps/i386/i486 - sysdeps/libm-i387/i686 - sysdeps/i386/fpu - sysdeps/libm-i387 - sysdeps/i386 - sysdeps/wordsize-32 - sysdeps/ieee754 - sysdeps/libm-ieee754 - sysdeps/generic - - Different machine architectures are conventionally subdirectories at -the top level of the `sysdeps' directory tree. For example, -`sysdeps/sparc' and `sysdeps/m68k'. These contain files specific to -those machine architectures, but not specific to any particular -operating system. There might be subdirectories for specializations of -those architectures, such as `sysdeps/m68k/68020'. Code which is -specific to the floating-point coprocessor used with a particular -machine should go in `sysdeps/MACHINE/fpu'. - - There are a few directories at the top level of the `sysdeps' -hierarchy that are not for particular machine architectures. - -`generic' - As described above (*note Porting::), this is the subdirectory - that every configuration implicitly uses after all others. - -`ieee754' - This directory is for code using the IEEE 754 floating-point - format, where the C type `float' is IEEE 754 single-precision - format, and `double' is IEEE 754 double-precision format. Usually - this directory is referred to in the `Implies' file in a machine - architecture-specific directory, such as `m68k/Implies'. - -`libm-ieee754' - This directory contains an implementation of a mathematical library - usable on platforms which use IEEE 754 conformant floating-point - arithmetic. - -`libm-i387' - This is a special case. Ideally the code should be in - `sysdeps/i386/fpu' but for various reasons it is kept aside. - -`posix' - This directory contains implementations of things in the library in - terms of POSIX.1 functions. This includes some of the POSIX.1 - functions themselves. Of course, POSIX.1 cannot be completely - implemented in terms of itself, so a configuration using just - `posix' cannot be complete. - -`unix' - This is the directory for Unix-like things. *Note Porting to - Unix::. `unix' implies `posix'. There are some special-purpose - subdirectories of `unix': - - `unix/common' - This directory is for things common to both BSD and System V - release 4. Both `unix/bsd' and `unix/sysv/sysv4' imply - `unix/common'. - - `unix/inet' - This directory is for `socket' and related functions on Unix - systems. `unix/inet/Subdirs' enables the `inet' top-level - subdirectory. `unix/common' implies `unix/inet'. - -`mach' - This is the directory for things based on the Mach microkernel - from CMU (including the GNU operating system). Other basic - operating systems (VMS, for example) would have their own - directories at the top level of the `sysdeps' hierarchy, parallel - to `unix' and `mach'. - - -File: libc.info, Node: Porting to Unix, Prev: Hierarchy Conventions, Up: Porting - -Porting the GNU C Library to Unix Systems ------------------------------------------ - - Most Unix systems are fundamentally very similar. There are -variations between different machines, and variations in what -facilities are provided by the kernel. But the interface to the -operating system facilities is, for the most part, pretty uniform and -simple. - - The code for Unix systems is in the directory `unix', at the top -level of the `sysdeps' hierarchy. This directory contains -subdirectories (and subdirectory trees) for various Unix variants. - - The functions which are system calls in most Unix systems are -implemented in assembly code, which is generated automatically from -specifications in files named `syscalls.list'. There are several such -files, one in `sysdeps/unix' and others in its subdirectories. Some -special system calls are implemented in files that are named with a -suffix of `.S'; for example, `_exit.S'. Files ending in `.S' are run -through the C preprocessor before being fed to the assembler. - - These files all use a set of macros that should be defined in -`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines -them; a `sysdep.h' file in another directory must finish defining them -for the particular machine and operating system variant. See -`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h' -implementations to see what these macros are and what they should do. - - The system-specific makefile for the `unix' directory -(`sysdeps/unix/Makefile') gives rules to generate several files from -the Unix system you are building the library on (which is assumed to be -the target system you are building the library _for_). All the -generated files are put in the directory where the object files are -kept; they should not affect the source tree itself. The files -generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c' -(for the `stdio' section of the library). - diff -u -udbrN glibc-2.3.2/manual/libc.info-55 glibc-2.3.2-200304020432/manual/libc.info-55 --- glibc-2.3.2/manual/libc.info-55 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-55 Thu Jan 1 01:00:00 1970 @@ -1,827 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

Many of our most important programs do -not come with free reference manuals and free introductory texts. -Documentation is an essential part of any software package; when an -important free software package does not come with a free manual and a -free tutorial, that is a major gap. We have many such gaps today. - - Consider Perl, for instance. The tutorial manuals that people -normally use are non-free. How did this come about? Because the -authors of those manuals published them with restrictive terms--no -copying, no modification, source files not available--which exclude -them from the free software world. - - That wasn't the first time this sort of thing happened, and it was -far from the last. Many times we have heard a GNU user eagerly -describe a manual that he is writing, his intended contribution to the -community, only to learn that he had ruined everything by signing a -publication contract to make it non-free. - - Free documentation, like free software, is a matter of freedom, not -price. The problem with the non-free manual is not that publishers -charge a price for printed copies--that in itself is fine. (The Free -Software Foundation sells printed copies of manuals, too.) The problem -is the restrictions on the use of the manual. Free manuals are -available in source code form, and give you permission to copy and -modify. Non-free manuals do not allow this. - - The criteria of freedom for a free manual are roughly the same as for -free software. Redistribution (including the normal kinds of -commercial redistribution) must be permitted, so that the manual can -accompany every copy of the program, both on-line and on paper. - - Permission for modification of the technical content is crucial too. -When people modify the software, adding or changing features, if they -are conscientious they will change the manual too--so they can provide -accurate and clear documentation for the modified program. A manual -that leaves you no choice but to write a new manual to document a -changed version of the program is not really available to our community. - - Some kinds of limits on the way modification is handled are -acceptable. For example, requirements to preserve the original -author's copyright notice, the distribution terms, or the list of -authors, are ok. It is also no problem to require modified versions to -include notice that they were modified. Even entire sections that may -not be deleted or changed are acceptable, as long as they deal with -nontechnical topics (like this one). These kinds of restrictions are -acceptable because they don't obstruct the community's normal use of -the manual. - - However, it must be possible to modify all the _technical_ content -of the manual, and then distribute the result in all the usual media, -through all the usual channels. Otherwise, the restrictions obstruct -the use of the manual, it is not free, and we need another manual to -replace it. - - Please spread the word about this issue. Our community continues to -lose manuals to proprietary publishing. If we spread the word that -free software needs free reference manuals and free tutorials, perhaps -the next person who wants to contribute by writing documentation will -realize, before it is too late, that only free manuals contribute to -the free software community. - - If you are writing documentation, please insist on publishing it -under the GNU Free Documentation License or another free documentation -license. Remember that this decision requires your approval--you don't -have to let the publisher decide. Some commercial publishers will use -a free license if you insist, but they will not propose the option; it -is up to you to raise the issue and say firmly that this is what you -want. If the publisher you are dealing with refuses, please try other -publishers. If you're not sure whether a proposed license is free, -write to . - - You can encourage commercial publishers to sell more free, copylefted -manuals and tutorials by buying them, and particularly by buying copies -from the publishers that paid for their writing or for major -improvements. Meanwhile, try to avoid buying non-free documentation at -all. Check the distribution terms of a manual before you buy it, and -insist that whoever seeks your business must respect your freedom. -Check the history of the book, and try reward the publishers that have -paid or pay the authors to work on it. - - The Free Software Foundation maintains a list of free documentation -published by other publishers, at -. - - -File: libc.info, Node: Copying, Next: Documentation License, Prev: Free Manuals, Up: Top - -GNU Lesser General Public License -********************************* - - Version 2.1, February 1999 - Copyright (C) 1991, 1999 Free Software Foundation, Inc. - 59 Temple Place -- Suite 330, Boston, MA 02111-1307, USA - - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - [This is the first released version of the Lesser GPL. It also counts - as the successor of the GNU Library Public License, version 2, hence the - version number 2.1.] - -Preamble --------- - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software--typically libraries--of the Free -Software Foundation and other authors who decide to use it. You can use -it too, but we suggest you first think carefully about whether this -license or the ordinary General Public License is the better strategy to -use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of it -in new free programs; and that you are informed that you can do these -things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know that -what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and is -quite different from the ordinary General Public License. We use this -license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does _Less_ to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it -becomes a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of free -software. For example, permission to use the GNU C Library in non-free -programs enables many more people to use the whole GNU operating -system, as well as its variant, the GNU/Linux operating system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run that -program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - 0. This License Agreement applies to any software library or other - program which contains a notice placed by the copyright holder or - other authorized party saying it may be distributed under the - terms of this Lesser General Public License (also called "this - License"). Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data - prepared so as to be conveniently linked with application programs - (which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work - which has been distributed under these terms. A "work based on the - Library" means either the Library or any derivative work under - copyright law: that is to say, a work containing the Library or a - portion of it, either verbatim or with modifications and/or - translated straightforwardly into another language. (Hereinafter, - translation is included without limitation in the term - "modification".) - - "Source code" for a work means the preferred form of the work for - making modifications to it. For a library, complete source code - means all the source code for all modules it contains, plus any - associated interface definition files, plus the scripts used to - control compilation and installation of the library. - - Activities other than copying, distribution and modification are - not covered by this License; they are outside its scope. The act - of running a program using the Library is not restricted, and - output from such a program is covered only if its contents - constitute a work based on the Library (independent of the use of - the Library in a tool for writing it). Whether that is true - depends on what the Library does and what the program that uses - the Library does. - - 1. You may copy and distribute verbatim copies of the Library's - complete source code as you receive it, in any medium, provided - that you conspicuously and appropriately publish on each copy an - appropriate copyright notice and disclaimer of warranty; keep - intact all the notices that refer to this License and to the - absence of any warranty; and distribute a copy of this License - along with the Library. - - You may charge a fee for the physical act of transferring a copy, - and you may at your option offer warranty protection in exchange - for a fee. - - 2. You may modify your copy or copies of the Library or any portion - of it, thus forming a work based on the Library, and copy and - distribute such modifications or work under the terms of Section 1 - above, provided that you also meet all of these conditions: - - a. The modified work must itself be a software library. - - b. You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c. You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d. If a facility in the modified Library refers to a function or - a table of data to be supplied by an application program that - uses the facility, other than as an argument passed when the - facility is invoked, then you must make a good faith effort - to ensure that, in the event an application does not supply - such function or table, the facility still operates, and - performs whatever part of its purpose remains meaningful. - - (For example, a function in a library to compute square roots - has a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function - must be optional: if the application does not supply it, the - square root function must still compute square roots.) - - These requirements apply to the modified work as a whole. If - identifiable sections of that work are not derived from the - Library, and can be reasonably considered independent and separate - works in themselves, then this License, and its terms, do not - apply to those sections when you distribute them as separate - works. But when you distribute the same sections as part of a - whole which is a work based on the Library, the distribution of - the whole must be on the terms of this License, whose permissions - for other licensees extend to the entire whole, and thus to each - and every part regardless of who wrote it. - - Thus, it is not the intent of this section to claim rights or - contest your rights to work written entirely by you; rather, the - intent is to exercise the right to control the distribution of - derivative or collective works based on the Library. - - In addition, mere aggregation of another work not based on the - Library with the Library (or with a work based on the Library) on - a volume of a storage or distribution medium does not bring the - other work under the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public - License instead of this License to a given copy of the Library. - To do this, you must alter all the notices that refer to this - License, so that they refer to the ordinary GNU General Public - License, version 2, instead of to this License. (If a newer - version than version 2 of the ordinary GNU General Public License - has appeared, then you can specify that version instead if you - wish.) Do not make any other change in these notices. - - Once this change is made in a given copy, it is irreversible for - that copy, so the ordinary GNU General Public License applies to - all subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of - the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or - derivative of it, under Section 2) in object code or executable - form under the terms of Sections 1 and 2 above provided that you - accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software - interchange. - - If distribution of object code is made by offering access to copy - from a designated place, then offering equivalent access to copy - the source code from the same place satisfies the requirement to - distribute the source code, even though third parties are not - compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the - Library, but is designed to work with the Library by being - compiled or linked with it, is called a "work that uses the - Library". Such a work, in isolation, is not a derivative work of - the Library, and therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library - creates an executable that is a derivative of the Library (because - it contains portions of the Library), rather than a "work that - uses the library". The executable is therefore covered by this - License. Section 6 states terms for distribution of such - executables. - - When a "work that uses the Library" uses material from a header - file that is part of the Library, the object code for the work may - be a derivative work of the Library even though the source code is - not. Whether this is true is especially significant if the work - can be linked without the Library, or if the work is itself a - library. The threshold for this to be true is not precisely - defined by law. - - If such an object file uses only numerical parameters, data - structure layouts and accessors, and small macros and small inline - functions (ten lines or less in length), then the use of the object - file is unrestricted, regardless of whether it is legally a - derivative work. (Executables containing this object code plus - portions of the Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may - distribute the object code for the work under the terms of Section - 6. Any executables containing that work also fall under Section 6, - whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or - link a "work that uses the Library" with the Library to produce a - work containing portions of the Library, and distribute that work - under terms of your choice, provided that the terms permit - modification of the work for the customer's own use and reverse - engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the - Library is used in it and that the Library and its use are covered - by this License. You must supply a copy of this License. If the - work during execution displays copyright notices, you must include - the copyright notice for the Library among them, as well as a - reference directing the user to the copy of this License. Also, - you must do one of these things: - - a. Accompany the work with the complete corresponding - machine-readable source code for the Library including - whatever changes were used in the work (which must be - distributed under Sections 1 and 2 above); and, if the work - is an executable linked with the Library, with the complete - machine-readable "work that uses the Library", as object code - and/or source code, so that the user can modify the Library - and then relink to produce a modified executable containing - the modified Library. (It is understood that the user who - changes the contents of definitions files in the Library will - not necessarily be able to recompile the application to use - the modified definitions.) - - b. Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run - time a copy of the library already present on the user's - computer system, rather than copying library functions into - the executable, and (2) will operate properly with a modified - version of the library, if the user installs one, as long as - the modified version is interface-compatible with the version - that the work was made with. - - c. Accompany the work with a written offer, valid for at least - three years, to give the same user the materials specified in - Subsection 6a, above, for a charge no more than the cost of - performing this distribution. - - d. If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the - above specified materials from the same place. - - e. Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the - Library" must include any data and utility programs needed for - reproducing the executable from it. However, as a special - exception, the materials to be distributed need not include - anything that is normally distributed (in either source or binary - form) with the major components (compiler, kernel, and so on) of - the operating system on which the executable runs, unless that - component itself accompanies the executable. - - It may happen that this requirement contradicts the license - restrictions of other proprietary libraries that do not normally - accompany the operating system. Such a contradiction means you - cannot use both them and the Library together in an executable - that you distribute. - - 7. You may place library facilities that are a work based on the - Library side-by-side in a single library together with other - library facilities not covered by this License, and distribute - such a combined library, provided that the separate distribution - of the work based on the Library and of the other library - facilities is otherwise permitted, and provided that you do these - two things: - - a. Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b. Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same - work. - - 8. You may not copy, modify, sublicense, link with, or distribute the - Library except as expressly provided under this License. Any - attempt otherwise to copy, modify, sublicense, link with, or - distribute the Library is void, and will automatically terminate - your rights under this License. However, parties who have - received copies, or rights, from you under this License will not - have their licenses terminated so long as such parties remain in - full compliance. - - 9. You are not required to accept this License, since you have not - signed it. However, nothing else grants you permission to modify - or distribute the Library or its derivative works. These actions - are prohibited by law if you do not accept this License. - Therefore, by modifying or distributing the Library (or any work - based on the Library), you indicate your acceptance of this - License to do so, and all its terms and conditions for copying, - distributing or modifying the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the - Library), the recipient automatically receives a license from the - original licensor to copy, distribute, link with or modify the - Library subject to these terms and conditions. You may not impose - any further restrictions on the recipients' exercise of the rights - granted herein. You are not responsible for enforcing compliance - by third parties with this License. - - 11. If, as a consequence of a court judgment or allegation of patent - infringement or for any other reason (not limited to patent - issues), conditions are imposed on you (whether by court order, - agreement or otherwise) that contradict the conditions of this - License, they do not excuse you from the conditions of this - License. If you cannot distribute so as to satisfy simultaneously - your obligations under this License and any other pertinent - obligations, then as a consequence you may not distribute the - Library at all. For example, if a patent license would not permit - royalty-free redistribution of the Library by all those who - receive copies directly or indirectly through you, then the only - way you could satisfy both it and this License would be to refrain - entirely from distribution of the Library. - - If any portion of this section is held invalid or unenforceable - under any particular circumstance, the balance of the section is - intended to apply, and the section as a whole is intended to apply - in other circumstances. - - It is not the purpose of this section to induce you to infringe any - patents or other property right claims or to contest validity of - any such claims; this section has the sole purpose of protecting - the integrity of the free software distribution system which is - implemented by public license practices. Many people have made - generous contributions to the wide range of software distributed - through that system in reliance on consistent application of that - system; it is up to the author/donor to decide if he or she is - willing to distribute software through any other system and a - licensee cannot impose that choice. - - This section is intended to make thoroughly clear what is believed - to be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in - certain countries either by patents or by copyrighted interfaces, - the original copyright holder who places the Library under this - License may add an explicit geographical distribution limitation - excluding those countries, so that distribution is permitted only - in or among countries not thus excluded. In such case, this - License incorporates the limitation as if written in the body of - this License. - - 13. The Free Software Foundation may publish revised and/or new - versions of the Lesser General Public License from time to time. - Such new versions will be similar in spirit to the present version, - but may differ in detail to address new problems or concerns. - - Each version is given a distinguishing version number. If the - Library specifies a version number of this License which applies - to it and "any later version", you have the option of following - the terms and conditions either of that version or of any later - version published by the Free Software Foundation. If the Library - does not specify a license version number, you may choose any - version ever published by the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free - programs whose distribution conditions are incompatible with these, - write to the author to ask for permission. For software which is - copyrighted by the Free Software Foundation, write to the Free - Software Foundation; we sometimes make exceptions for this. Our - decision will be guided by the two goals of preserving the free - status of all derivatives of our free software and of promoting - the sharing and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO - WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE - LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT - HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT - WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT - NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND - FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE - QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE - LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY - SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN - WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY - MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE - LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, - INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR - INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF - DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU - OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY - OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN - ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - -How to Apply These Terms to Your New Libraries ----------------------------------------------- - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of -the ordinary General Public License). - - To apply these terms, attach the following notices to the library. -It is safest to attach them to the start of each source file to most -effectively convey the exclusion of warranty; and each file should have -at least the "copyright" line and a pointer to where the full notice is -found. - - ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES. - Copyright (C) YEAR NAME OF AUTHOR - - This library is free software; you can redistribute it and/or modify it - under the terms of the GNU Lesser General Public License as published by - the Free Software Foundation; either version 2.1 of the License, or (at - your option) any later version. - - This library is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

PREAMBLE - - The purpose of this License is to make a manual, textbook, or other - written document "free" in the sense of freedom: to assure everyone - the effective freedom to copy and redistribute it, with or without - modifying it, either commercially or noncommercially. Secondarily, - this License preserves for the author and publisher a way to get - credit for their work, while not being considered responsible for - modifications made by others. - - This License is a kind of "copyleft", which means that derivative - works of the document must themselves be free in the same sense. - It complements the GNU General Public License, which is a copyleft - license designed for free software. - - We have designed this License in order to use it for manuals for - free software, because free software needs free documentation: a - free program should come with manuals providing the same freedoms - that the software does. But this License is not limited to - software manuals; it can be used for any textual work, regardless - of subject matter or whether it is published as a printed book. - We recommend this License principally for works whose purpose is - instruction or reference. - - 1. APPLICABILITY AND DEFINITIONS - - This License applies to any manual or other work that contains a - notice placed by the copyright holder saying it can be distributed - under the terms of this License. The "Document", below, refers to - any such manual or work. Any member of the public is a licensee, - and is addressed as "you". - - A "Modified Version" of the Document means any work containing the - Document or a portion of it, either copied verbatim, or with - modifications and/or translated into another language. - - A "Secondary Section" is a named appendix or a front-matter - section of the Document that deals exclusively with the - relationship of the publishers or authors of the Document to the - Document's overall subject (or to related matters) and contains - nothing that could fall directly within that overall subject. - (For example, if the Document is in part a textbook of - mathematics, a Secondary Section may not explain any mathematics.) - The relationship could be a matter of historical connection with - the subject or with related matters, or of legal, commercial, - philosophical, ethical or political position regarding them. - - The "Invariant Sections" are certain Secondary Sections whose - titles are designated, as being those of Invariant Sections, in - the notice that says that the Document is released under this - License. - - The "Cover Texts" are certain short passages of text that are - listed, as Front-Cover Texts or Back-Cover Texts, in the notice - that says that the Document is released under this License. - - A "Transparent" copy of the Document means a machine-readable copy, - represented in a format whose specification is available to the - general public, whose contents can be viewed and edited directly - and straightforwardly with generic text editors or (for images - composed of pixels) generic paint programs or (for drawings) some - widely available drawing editor, and that is suitable for input to - text formatters or for automatic translation to a variety of - formats suitable for input to text formatters. A copy made in an - otherwise Transparent file format whose markup has been designed - to thwart or discourage subsequent modification by readers is not - Transparent. A copy that is not "Transparent" is called "Opaque". - - Examples of suitable formats for Transparent copies include plain - ASCII without markup, Texinfo input format, LaTeX input format, - SGML or XML using a publicly available DTD, and - standard-conforming simple HTML designed for human modification. - Opaque formats include PostScript, PDF, proprietary formats that - can be read and edited only by proprietary word processors, SGML - or XML for which the DTD and/or processing tools are not generally - available, and the machine-generated HTML produced by some word - processors for output purposes only. - - The "Title Page" means, for a printed book, the title page itself, - plus such following pages as are needed to hold, legibly, the - material this License requires to appear in the title page. For - works in formats which do not have any title page as such, "Title - Page" means the text near the most prominent appearance of the - work's title, preceding the beginning of the body of the text. - - 2. VERBATIM COPYING - - You may copy and distribute the Document in any medium, either - commercially or noncommercially, provided that this License, the - copyright notices, and the license notice saying this License - applies to the Document are reproduced in all copies, and that you - add no other conditions whatsoever to those of this License. You - may not use technical measures to obstruct or control the reading - or further copying of the copies you make or distribute. However, - you may accept compensation in exchange for copies. If you - distribute a large enough number of copies you must also follow - the conditions in section 3. - - You may also lend copies, under the same conditions stated above, - and you may publicly display copies. - - 3. COPYING IN QUANTITY - - If you publish printed copies of the Document numbering more than - 100, and the Document's license notice requires Cover Texts, you - must enclose the copies in covers that carry, clearly and legibly, - all these Cover Texts: Front-Cover Texts on the front cover, and - Back-Cover Texts on the back cover. Both covers must also clearly - and legibly identify you as the publisher of these copies. The - front cover must present the full title with all words of the - title equally prominent and visible. You may add other material - on the covers in addition. Copying with changes limited to the - covers, as long as they preserve the title of the Document and - satisfy these conditions, can be treated as verbatim copying in - other respects. - - If the required texts for either cover are too voluminous to fit - legibly, you should put the first ones listed (as many as fit - reasonably) on the actual cover, and continue the rest onto - adjacent pages. - - If you publish or distribute Opaque copies of the Document - numbering more than 100, you must either include a - machine-readable Transparent copy along with each Opaque copy, or - state in or with each Opaque copy a publicly-accessible - computer-network location containing a complete Transparent copy - of the Document, free of added material, which the general - network-using public has access to download anonymously at no - charge using public-standard network protocols. If you use the - latter option, you must take reasonably prudent steps, when you - begin distribution of Opaque copies in quantity, to ensure that - this Transparent copy will remain thus accessible at the stated - location until at least one year after the last time you - distribute an Opaque copy (directly or through your agents or - retailers) of that edition to the public. - - It is requested, but not required, that you contact the authors of - the Document well before redistributing any large number of - copies, to give them a chance to provide you with an updated - version of the Document. - - 4. MODIFICATIONS - - You may copy and distribute a Modified Version of the Document - under the conditions of sections 2 and 3 above, provided that you - release the Modified Version under precisely this License, with - the Modified Version filling the role of the Document, thus - licensing distribution and modification of the Modified Version to - whoever possesses a copy of it. In addition, you must do these - things in the Modified Version: - - A. Use in the Title Page (and on the covers, if any) a title - distinct from that of the Document, and from those of - previous versions (which should, if there were any, be listed - in the History section of the Document). You may use the - same title as a previous version if the original publisher of - that version gives permission. - - B. List on the Title Page, as authors, one or more persons or - entities responsible for authorship of the modifications in - the Modified Version, together with at least five of the - principal authors of the Document (all of its principal - authors, if it has less than five). - - C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. - - D. Preserve all the copyright notices of the Document. - - E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. - - F. Include, immediately after the copyright notices, a license - notice giving the public permission to use the Modified - Version under the terms of this License, in the form shown in - the Addendum below. - - G. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's - license notice. - - H. Include an unaltered copy of this License. - - I. Preserve the section entitled "History", and its title, and - add to it an item stating at least the title, year, new - authors, and publisher of the Modified Version as given on - the Title Page. If there is no section entitled "History" in - the Document, create one stating the title, year, authors, - and publisher of the Document as given on its Title Page, - then add an item describing the Modified Version as stated in - the previous sentence. - - J. Preserve the network location, if any, given in the Document - for public access to a Transparent copy of the Document, and - likewise the network locations given in the Document for - previous versions it was based on. These may be placed in - the "History" section. You may omit a network location for a - work that was published at least four years before the - Document itself, or if the original publisher of the version - it refers to gives permission. - - K. In any section entitled "Acknowledgments" or "Dedications", - preserve the section's title, and preserve in the section all - the substance and tone of each of the contributor - acknowledgments and/or dedications given therein. - - L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section - titles. - - M. Delete any section entitled "Endorsements". Such a section - may not be included in the Modified Version. - - N. Do not retitle any existing section as "Endorsements" or to - conflict in title with any Invariant Section. - - If the Modified Version includes new front-matter sections or - appendices that qualify as Secondary Sections and contain no - material copied from the Document, you may at your option - designate some or all of these sections as invariant. To do this, - add their titles to the list of Invariant Sections in the Modified - Version's license notice. These titles must be distinct from any - other section titles. - - You may add a section entitled "Endorsements", provided it contains - nothing but endorsements of your Modified Version by various - parties--for example, statements of peer review or that the text - has been approved by an organization as the authoritative - definition of a standard. - - You may add a passage of up to five words as a Front-Cover Text, - and a passage of up to 25 words as a Back-Cover Text, to the end - of the list of Cover Texts in the Modified Version. Only one - passage of Front-Cover Text and one of Back-Cover Text may be - added by (or through arrangements made by) any one entity. If the - Document already includes a cover text for the same cover, - previously added by you or by arrangement made by the same entity - you are acting on behalf of, you may not add another; but you may - replace the old one, on explicit permission from the previous - publisher that added the old one. - - The author(s) and publisher(s) of the Document do not by this - License give permission to use their names for publicity for or to - assert or imply endorsement of any Modified Version. - - 5. COMBINING DOCUMENTS - - You may combine the Document with other documents released under - this License, under the terms defined in section 4 above for - modified versions, provided that you include in the combination - all of the Invariant Sections of all of the original documents, - unmodified, and list them all as Invariant Sections of your - combined work in its license notice. - - The combined work need only contain one copy of this License, and - multiple identical Invariant Sections may be replaced with a single - copy. If there are multiple Invariant Sections with the same name - but different contents, make the title of each such section unique - by adding at the end of it, in parentheses, the name of the - original author or publisher of that section if known, or else a - unique number. Make the same adjustment to the section titles in - the list of Invariant Sections in the license notice of the - combined work. - - In the combination, you must combine any sections entitled - "History" in the various original documents, forming one section - entitled "History"; likewise combine any sections entitled - "Acknowledgments", and any sections entitled "Dedications". You - must delete all sections entitled "Endorsements." - - 6. COLLECTIONS OF DOCUMENTS - - You may make a collection consisting of the Document and other - documents released under this License, and replace the individual - copies of this License in the various documents with a single copy - that is included in the collection, provided that you follow the - rules of this License for verbatim copying of each of the - documents in all other respects. - - You may extract a single document from such a collection, and - distribute it individually under this License, provided you insert - a copy of this License into the extracted document, and follow - this License in all other respects regarding verbatim copying of - that document. - - 7. AGGREGATION WITH INDEPENDENT WORKS - - A compilation of the Document or its derivatives with other - separate and independent documents or works, in or on a volume of - a storage or distribution medium, does not as a whole count as a - Modified Version of the Document, provided no compilation - copyright is claimed for the compilation. Such a compilation is - called an "aggregate", and this License does not apply to the - other self-contained works thus compiled with the Document, on - account of their being thus compiled, if they are not themselves - derivative works of the Document. - - If the Cover Text requirement of section 3 is applicable to these - copies of the Document, then if the Document is less than one - quarter of the entire aggregate, the Document's Cover Texts may be - placed on covers that surround only the Document within the - aggregate. Otherwise they must appear on covers around the whole - aggregate. - - 8. TRANSLATION - - Translation is considered a kind of modification, so you may - distribute translations of the Document under the terms of section - 4. Replacing Invariant Sections with translations requires special - permission from their copyright holders, but you may include - translations of some or all Invariant Sections in addition to the - original versions of these Invariant Sections. You may include a - translation of this License provided that you also include the - original English version of this License. In case of a - disagreement between the translation and the original English - version of this License, the original English version will prevail. - - 9. TERMINATION - - You may not copy, modify, sublicense, or distribute the Document - except as expressly provided for under this License. Any other - attempt to copy, modify, sublicense or distribute the Document is - void, and will automatically terminate your rights under this - License. However, parties who have received copies, or rights, - from you under this License will not have their licenses - terminated so long as such parties remain in full compliance. - - 10. FUTURE REVISIONS OF THIS LICENSE - - The Free Software Foundation may publish new, revised versions of - the GNU Free Documentation License from time to time. Such new - versions will be similar in spirit to the present version, but may - differ in detail to address new problems or concerns. See - `http://www.gnu.org/copyleft/'. - - Each version of the License is given a distinguishing version - number. If the Document specifies that a particular numbered - version of this License "or any later version" applies to it, you - have the option of following the terms and conditions either of - that specified version or of any later version that has been - published (not as a draft) by the Free Software Foundation. If - the Document does not specify a version number of this License, - you may choose any version ever published (not as a draft) by the - Free Software Foundation. - -ADDENDUM: How to use this License for your documents ----------------------------------------------------- - - To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and license -notices just after the title page: - - Copyright (C) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.1 - or any later version published by the Free Software Foundation; - with the Invariant Sections being LIST THEIR TITLES, with the - Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. - A copy of the license is included in the section entitled ``GNU - Free Documentation License''. - - If you have no Invariant Sections, write "with no Invariant Sections" -instead of saying which ones are invariant.

Although the original ISO C90 standard already defined the -type `wchar_t', no functions operating on them were defined. - - The general design of the classification functions for wide -characters is more general. It allows extensions to the set of -available classifications, beyond those which are always available. -The POSIX standard specifies how extensions can be made, and this is -already implemented in the GNU C library implementation of the -`localedef' program. - - The character class functions are normally implemented with bitsets, -with a bitset per character. For a given character, the appropriate -bitset is read from a table and a test is performed as to whether a -certain bit is set. Which bit is tested for is determined by the class. - - For the wide character classification functions this is made visible. -There is a type classification type defined, a function to retrieve this -value for a given class, and a function to test whether a given -character is in this class, using the classification value. On top of -this the normal character classification functions as used for `char' -objects can be defined. - - - Data type: wctype_t - The `wctype_t' can hold a value which represents a character class. - The only defined way to generate such a value is by using the - `wctype' function. - - This type is defined in `wctype.h'. - - - Function: wctype_t wctype (const char *PROPERTY) - The `wctype' returns a value representing a class of wide - characters which is identified by the string PROPERTY. Beside - some standard properties each locale can define its own ones. In - case no property with the given name is known for the current - locale selected for the `LC_CTYPE' category, the function returns - zero. - - The properties known in every locale are: - - `"alnum"' `"alpha"' `"cntrl"' `"digit"' - `"graph"' `"lower"' `"print"' `"punct"' - `"space"' `"upper"' `"xdigit"' - - This function is declared in `wctype.h'. - - To test the membership of a character to one of the non-standard -classes the ISO C standard defines a completely new function. - - - Function: int iswctype (wint_t WC, wctype_t DESC) - This function returns a nonzero value if WC is in the character - class specified by DESC. DESC must previously be returned by a - successful call to `wctype'. - - This function is declared in `wctype.h'. - - To make it easier to use the commonly-used classification functions, -they are defined in the C library. There is no need to use `wctype' if -the property string is one of the known character classes. In some -situations it is desirable to construct the property strings, and then -it is important that `wctype' can also handle the standard classes. - - - Function: int iswalnum (wint_t WC) - This function returns a nonzero value if WC is an alphanumeric - character (a letter or number); in other words, if either - `iswalpha' or `iswdigit' is true of a character, then `iswalnum' - is also true. - - This function can be implemented using - - iswctype (wc, wctype ("alnum")) - - It is declared in `wctype.h'. - - - Function: int iswalpha (wint_t WC) - Returns true if WC is an alphabetic character (a letter). If - `iswlower' or `iswupper' is true of a character, then `iswalpha' - is also true. - - In some locales, there may be additional characters for which - `iswalpha' is true--letters which are neither upper case nor lower - case. But in the standard `"C"' locale, there are no such - additional characters. - - This function can be implemented using - - iswctype (wc, wctype ("alpha")) - - It is declared in `wctype.h'. - - - Function: int iswcntrl (wint_t WC) - Returns true if WC is a control character (that is, a character - that is not a printing character). - - This function can be implemented using - - iswctype (wc, wctype ("cntrl")) - - It is declared in `wctype.h'. - - - Function: int iswdigit (wint_t WC) - Returns true if WC is a digit (e.g., `0' through `9'). Please - note that this function does not only return a nonzero value for - _decimal_ digits, but for all kinds of digits. A consequence is - that code like the following will *not* work unconditionally for - wide characters: - - n = 0; - while (iswdigit (*wc)) - { - n *= 10; - n += *wc++ - L'0'; - } - - This function can be implemented using - - iswctype (wc, wctype ("digit")) - - It is declared in `wctype.h'. - - - Function: int iswgraph (wint_t WC) - Returns true if WC is a graphic character; that is, a character - that has a glyph associated with it. The whitespace characters - are not considered graphic. - - This function can be implemented using - - iswctype (wc, wctype ("graph")) - - It is declared in `wctype.h'. - - - Function: int iswlower (wint_t WC) - Returns true if WC is a lower-case letter. The letter need not be - from the Latin alphabet, any alphabet representable is valid. - - This function can be implemented using - - iswctype (wc, wctype ("lower")) - - It is declared in `wctype.h'. - - - Function: int iswprint (wint_t WC) - Returns true if WC is a printing character. Printing characters - include all the graphic characters, plus the space (` ') character. - - This function can be implemented using - - iswctype (wc, wctype ("print")) - - It is declared in `wctype.h'. - - - Function: int iswpunct (wint_t WC) - Returns true if WC is a punctuation character. This means any - printing character that is not alphanumeric or a space character. - - This function can be implemented using - - iswctype (wc, wctype ("punct")) - - It is declared in `wctype.h'. - - - Function: int iswspace (wint_t WC) - Returns true if WC is a "whitespace" character. In the standard - `"C"' locale, `iswspace' returns true for only the standard - whitespace characters: - - `L' '' - space - - `L'\f'' - formfeed - - `L'\n'' - newline - - `L'\r'' - carriage return - - `L'\t'' - horizontal tab - - `L'\v'' - vertical tab - - This function can be implemented using - - iswctype (wc, wctype ("space")) - - It is declared in `wctype.h'. - - - Function: int iswupper (wint_t WC) - Returns true if WC is an upper-case letter. The letter need not be - from the Latin alphabet, any alphabet representable is valid. - - This function can be implemented using - - iswctype (wc, wctype ("upper")) - - It is declared in `wctype.h'. - - - Function: int iswxdigit (wint_t WC) - Returns true if WC is a hexadecimal digit. Hexadecimal digits - include the normal decimal digits `0' through `9' and the letters - `A' through `F' and `a' through `f'. - - This function can be implemented using - - iswctype (wc, wctype ("xdigit")) - - It is declared in `wctype.h'. - - The GNU C library also provides a function which is not defined in -the ISO C standard but which is available as a version for single byte -characters as well. - - - Function: int iswblank (wint_t WC) - Returns true if WC is a blank character; that is, a space or a tab. - This function is a GNU extension. It is declared in `wchar.h'. - - -File: libc.info, Node: Using Wide Char Classes, Next: Wide Character Case Conversion, Prev: Classification of Wide Characters, Up: Character Handling - -Notes on using the wide character classes -========================================= - - The first note is probably not astonishing but still occasionally a -cause of problems. The `iswXXX' functions can be implemented using -macros and in fact, the GNU C library does this. They are still -available as real functions but when the `wctype.h' header is included -the macros will be used. This is the same as the `char' type versions -of these functions. - - The second note covers something new. It can be best illustrated by -a (real-world) example. The first piece of code is an excerpt from the -original code. It is truncated a bit but the intention should be clear. - - int - is_in_class (int c, const char *class) - { - if (strcmp (class, "alnum") == 0) - return isalnum (c); - if (strcmp (class, "alpha") == 0) - return isalpha (c); - if (strcmp (class, "cntrl") == 0) - return iscntrl (c); - ... - return 0; - } - - Now, with the `wctype' and `iswctype' you can avoid the `if' -cascades, but rewriting the code as follows is wrong: - - int - is_in_class (int c, const char *class) - { - wctype_t desc = wctype (class); - return desc ? iswctype ((wint_t) c, desc) : 0; - } - - The problem is that it is not guaranteed that the wide character -representation of a single-byte character can be found using casting. -In fact, usually this fails miserably. The correct solution to this -problem is to write the code as follows: - - int - is_in_class (int c, const char *class) - { - wctype_t desc = wctype (class); - return desc ? iswctype (btowc (c), desc) : 0; - } - - *Note Converting a Character::, for more information on `btowc'. -Note that this change probably does not improve the performance of the -program a lot since the `wctype' function still has to make the string -comparisons. It gets really interesting if the `is_in_class' function -is called more than once for the same class name. In this case the -variable DESC could be computed once and reused for all the calls. -Therefore the above form of the function is probably not the final one. - - -File: libc.info, Node: Wide Character Case Conversion, Prev: Using Wide Char Classes, Up: Character Handling - -Mapping of wide characters. -=========================== - - The classification functions are also generalized by the ISO C -standard. Instead of just allowing the two standard mappings, a locale -can contain others. Again, the `localedef' program already supports -generating such locale data files. - - - Data Type: wctrans_t - This data type is defined as a scalar type which can hold a value - representing the locale-dependent character mapping. There is no - way to construct such a value apart from using the return value of - the `wctrans' function. - - This type is defined in `wctype.h'. - - - Function: wctrans_t wctrans (const char *PROPERTY) - The `wctrans' function has to be used to find out whether a named - mapping is defined in the current locale selected for the - `LC_CTYPE' category. If the returned value is non-zero, you can - use it afterwards in calls to `towctrans'. If the return value is - zero no such mapping is known in the current locale. - - Beside locale-specific mappings there are two mappings which are - guaranteed to be available in every locale: - - `"tolower"' `"toupper"' - - These functions are declared in `wctype.h'. - - - Function: wint_t towctrans (wint_t WC, wctrans_t DESC) - `towctrans' maps the input character WC according to the rules of - the mapping for which DESC is a descriptor, and returns the value - it finds. DESC must be obtained by a successful call to `wctrans'. - - This function is declared in `wctype.h'. - - For the generally available mappings, the ISO C standard defines -convenient shortcuts so that it is not necessary to call `wctrans' for -them. - - - Function: wint_t towlower (wint_t WC) - If WC is an upper-case letter, `towlower' returns the corresponding - lower-case letter. If WC is not an upper-case letter, WC is - returned unchanged. - - `towlower' can be implemented using - - towctrans (wc, wctrans ("tolower")) - - This function is declared in `wctype.h'. - - - Function: wint_t towupper (wint_t WC) - If WC is a lower-case letter, `towupper' returns the corresponding - upper-case letter. Otherwise WC is returned unchanged. - - `towupper' can be implemented using - - towctrans (wc, wctrans ("toupper")) - - This function is declared in `wctype.h'. - - The same warnings given in the last section for the use of the wide -character classification functions apply here. It is not possible to -simply cast a `char' type value to a `wint_t' and use it as an argument -to `towctrans' calls. - - -File: libc.info, Node: String and Array Utilities, Next: Character Set Handling, Prev: Character Handling, Up: Top - -String and Array Utilities -************************** - - Operations on strings (or arrays of characters) are an important -part of many programs. The GNU C library provides an extensive set of -string utility functions, including functions for copying, -concatenating, comparing, and searching strings. Many of these -functions can also operate on arbitrary regions of storage; for -example, the `memcpy' function can be used to copy the contents of any -kind of array. - - It's fairly common for beginning C programmers to "reinvent the -wheel" by duplicating this functionality in their own code, but it pays -to become familiar with the library functions and to make use of them, -since this offers benefits in maintenance, efficiency, and portability. - - For instance, you could easily compare one string to another in two -lines of C code, but if you use the built-in `strcmp' function, you're -less likely to make a mistake. And, since these library functions are -typically highly optimized, your program may run faster too. - -* Menu: - -* Representation of Strings:: Introduction to basic concepts. -* String/Array Conventions:: Whether to use a string function or an - arbitrary array function. -* String Length:: Determining the length of a string. -* Copying and Concatenation:: Functions to copy the contents of strings - and arrays. -* String/Array Comparison:: Functions for byte-wise and character-wise - comparison. -* Collation Functions:: Functions for collating strings. -* Search Functions:: Searching for a specific element or substring. -* Finding Tokens in a String:: Splitting a string into tokens by looking - for delimiters. -* strfry:: Function for flash-cooking a string. -* Trivial Encryption:: Obscuring data. -* Encode Binary Data:: Encoding and Decoding of Binary Data. -* Argz and Envz Vectors:: Null-separated string vectors. - - -File: libc.info, Node: Representation of Strings, Next: String/Array Conventions, Up: String and Array Utilities - -Representation of Strings -========================= - - This section is a quick summary of string concepts for beginning C -programmers. It describes how character strings are represented in C -and some common pitfalls. If you are already familiar with this -material, you can skip this section. - - A "string" is an array of `char' objects. But string-valued -variables are usually declared to be pointers of type `char *'. Such -variables do not include space for the text of a string; that has to be -stored somewhere else--in an array variable, a string constant, or -dynamically allocated memory (*note Memory Allocation::). It's up to -you to store the address of the chosen memory space into the pointer -variable. Alternatively you can store a "null pointer" in the pointer -variable. The null pointer does not point anywhere, so attempting to -reference the string it points to gets an error. - - "string" normally refers to multibyte character strings as opposed to -wide character strings. Wide character strings are arrays of type -`wchar_t' and as for multibyte character strings usually pointers of -type `wchar_t *' are used. - - By convention, a "null character", `'\0'', marks the end of a -multibyte character string and the "null wide character", `L'\0'', -marks the end of a wide character string. For example, in testing to -see whether the `char *' variable P points to a null character marking -the end of a string, you can write `!*P' or `*P == '\0''. - - A null character is quite different conceptually from a null pointer, -although both are represented by the integer `0'. - - "String literals" appear in C program source as strings of -characters between double-quote characters (`"') where the initial -double-quote character is immediately preceded by a capital `L' (ell) -character (as in `L"foo"'). In ISO C, string literals can also be -formed by "string concatenation": `"a" "b"' is the same as `"ab"'. For -wide character strings one can either use `L"a" L"b"' or `L"a" "b"'. -Modification of string literals is not allowed by the GNU C compiler, -because literals are placed in read-only storage. - - Character arrays that are declared `const' cannot be modified -either. It's generally good style to declare non-modifiable string -pointers to be of type `const char *', since this often allows the C -compiler to detect accidental modifications as well as providing some -amount of documentation about what your program intends to do with the -string. - - The amount of memory allocated for the character array may extend -past the null character that normally marks the end of the string. In -this document, the term "allocated size" is always used to refer to the -total amount of memory allocated for the string, while the term -"length" refers to the number of characters up to (but not including) -the terminating null character. - - A notorious source of program bugs is trying to put more characters -in a string than fit in its allocated size. When writing code that -extends strings or moves characters into a pre-allocated array, you -should be very careful to keep track of the length of the text and make -explicit checks for overflowing the array. Many of the library -functions _do not_ do this for you! Remember also that you need to -allocate an extra byte to hold the null character that marks the end of -the string. - - Originally strings were sequences of bytes where each byte -represents a single character. This is still true today if the strings -are encoded using a single-byte character encoding. Things are -different if the strings are encoded using a multibyte encoding (for -more information on encodings see *Note Extended Char Intro::). There -is no difference in the programming interface for these two kind of -strings; the programmer has to be aware of this and interpret the byte -sequences accordingly. - - But since there is no separate interface taking care of these -differences the byte-based string functions are sometimes hard to use. -Since the count parameters of these functions specify bytes a call to -`strncpy' could cut a multibyte character in the middle and put an -incomplete (and therefore unusable) byte sequence in the target buffer. - - To avoid these problems later versions of the ISO C standard -introduce a second set of functions which are operating on "wide -characters" (*note Extended Char Intro::). These functions don't have -the problems the single-byte versions have since every wide character is -a legal, interpretable value. This does not mean that cutting wide -character strings at arbitrary points is without problems. It normally -is for alphabet-based languages (except for non-normalized text) but -languages based on syllables still have the problem that more than one -wide character is necessary to complete a logical unit. This is a -higher level problem which the C library functions are not designed to -solve. But it is at least good that no invalid byte sequences can be -created. Also, the higher level functions can also much easier operate -on wide character than on multibyte characters so that a general advise -is to use wide characters internally whenever text is more than simply -copied. - - The remaining of this chapter will discuss the functions for handling -wide character strings in parallel with the discussion of the multibyte -character strings since there is almost always an exact equivalent -available. - - -File: libc.info, Node: String/Array Conventions, Next: String Length, Prev: Representation of Strings, Up: String and Array Utilities - -String and Array Conventions -============================ - - This chapter describes both functions that work on arbitrary arrays -or blocks of memory, and functions that are specific to null-terminated -arrays of characters and wide characters. - - Functions that operate on arbitrary blocks of memory have names -beginning with `mem' and `wmem' (such as `memcpy' and `wmemcpy') and -invariably take an argument which specifies the size (in bytes and wide -characters respectively) of the block of memory to operate on. The -array arguments and return values for these functions have type `void -*' or `wchar_t'. As a matter of style, the elements of the arrays used -with the `mem' functions are referred to as "bytes". You can pass any -kind of pointer to these functions, and the `sizeof' operator is useful -in computing the value for the size argument. Parameters to the `wmem' -functions must be of type `wchar_t *'. These functions are not really -usable with anything but arrays of this type. - - In contrast, functions that operate specifically on strings and wide -character strings have names beginning with `str' and `wcs' -respectively (such as `strcpy' and `wcscpy') and look for a null -character to terminate the string instead of requiring an explicit size -argument to be passed. (Some of these functions accept a specified -maximum length, but they also check for premature termination with a -null character.) The array arguments and return values for these -functions have type `char *' and `wchar_t *' respectively, and the -array elements are referred to as "characters" and "wide characters". - - In many cases, there are both `mem' and `str'/`wcs' versions of a -function. The one that is more appropriate to use depends on the exact -situation. When your program is manipulating arbitrary arrays or -blocks of storage, then you should always use the `mem' functions. On -the other hand, when you are manipulating null-terminated strings it is -usually more convenient to use the `str'/`wcs' functions, unless you -already know the length of the string in advance. The `wmem' functions -should be used for wide character arrays with known size. - - Some of the memory and string functions take single characters as -arguments. Since a value of type `char' is automatically promoted into -an value of type `int' when used as a parameter, the functions are -declared with `int' as the type of the parameter in question. In case -of the wide character function the situation is similarly: the -parameter type for a single wide character is `wint_t' and not -`wchar_t'. This would for many implementations not be necessary since -the `wchar_t' is large enough to not be automatically promoted, but -since the ISO C standard does not require such a choice of types the -`wint_t' type is used. - - -File: libc.info, Node: String Length, Next: Copying and Concatenation, Prev: String/Array Conventions, Up: String and Array Utilities - -String Length -============= - - You can get the length of a string using the `strlen' function. -This function is declared in the header file `string.h'. - - - Function: size_t strlen (const char *S) - The `strlen' function returns the length of the null-terminated - string S in bytes. (In other words, it returns the offset of the - terminating null character within the array.) - - For example, - strlen ("hello, world") - => 12 - - When applied to a character array, the `strlen' function returns - the length of the string stored there, not its allocated size. - You can get the allocated size of the character array that holds a - string using the `sizeof' operator: - - char string[32] = "hello, world"; - sizeof (string) - => 32 - strlen (string) - => 12 - - But beware, this will not work unless STRING is the character - array itself, not a pointer to it. For example: - - char string[32] = "hello, world"; - char *ptr = string; - sizeof (string) - => 32 - sizeof (ptr) - => 4 /* (on a machine with 4 byte pointers) */ - - This is an easy mistake to make when you are working with - functions that take string arguments; those arguments are always - pointers, not arrays. - - It must also be noted that for multibyte encoded strings the return - value does not have to correspond to the number of characters in - the string. To get this value the string can be converted to wide - characters and `wcslen' can be used or something like the following - code can be used: - - /* The input is in `string'. - The length is expected in `n'. */ - { - mbstate_t t; - char *scopy = string; - /* In initial state. */ - memset (&t, '\0', sizeof (t)); - /* Determine number of characters. */ - n = mbsrtowcs (NULL, &scopy, strlen (scopy), &t); - } - - This is cumbersome to do so if the number of characters (as - opposed to bytes) is needed often it is better to work with wide - characters. - - The wide character equivalent is declared in `wchar.h'. - - - Function: size_t wcslen (const wchar_t *WS) - The `wcslen' function is the wide character equivalent to - `strlen'. The return value is the number of wide characters in the - wide character string pointed to by WS (this is also the offset of - the terminating null wide character of WS). - - Since there are no multi wide character sequences making up one - character the return value is not only the offset in the array, it - is also the number of wide characters. - - This function was introduced in Amendment 1 to ISO C90. - - - Function: size_t strnlen (const char *S, size_t MAXLEN) - The `strnlen' function returns the length of the string S in bytes - if this length is smaller than MAXLEN bytes. Otherwise it returns - MAXLEN. Therefore this function is equivalent to `(strlen (S) < n - ? strlen (S) : MAXLEN)' but it is more efficient and works even if - the string S is not null-terminated. - - char string[32] = "hello, world"; - strnlen (string, 32) - => 12 - strnlen (string, 5) - => 5 - - This function is a GNU extension and is declared in `string.h'. - - - Function: size_t wcsnlen (const wchar_t *WS, size_t MAXLEN) - `wcsnlen' is the wide character equivalent to `strnlen'. The - MAXLEN parameter specifies the maximum number of wide characters. - - This function is a GNU extension and is declared in `wchar.h'. - diff -u -udbrN glibc-2.3.2/manual/libc.info-60 glibc-2.3.2-200304020432/manual/libc.info-60 --- glibc-2.3.2/manual/libc.info-60 Sat Mar 1 02:39:41 2003 +++ glibc-2.3.2-200304020432/manual/libc.info-60 Thu Jan 1 01:00:00 1970 @@ -1,1115 +0,0 @@ -This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. - -INFO-DIR-SECTION GNU libraries -START-INFO-DIR-ENTRY -* Libc: (libc).

The `str' and `mem' functions are declared in the header -file `string.h' while the `wstr' and `wmem' functions are declared in -the file `wchar.h'. - - A helpful way to remember the ordering of the arguments to the -functions in this section is that it corresponds to an assignment -expression, with the destination array specified to the left of the -source array. All of these functions return the address of the -destination array. - - Most of these functions do not work properly if the source and -destination arrays overlap. For example, if the beginning of the -destination array overlaps the end of the source array, the original -contents of that part of the source array may get overwritten before it -is copied. Even worse, in the case of the string functions, the null -character marking the end of the string may be lost, and the copy -function might get stuck in a loop trashing all the memory allocated to -your program. - - All functions that have problems copying between overlapping arrays -are explicitly identified in this manual. In addition to functions in -this section, there are a few others like `sprintf' (*note Formatted -Output Functions::) and `scanf' (*note Formatted Input Functions::). - - - Function: void * memcpy (void *restrict TO, const void *restrict - FROM, size_t SIZE) - The `memcpy' function copies SIZE bytes from the object beginning - at FROM into the object beginning at TO. The behavior of this - function is undefined if the two arrays TO and FROM overlap; use - `memmove' instead if overlapping is possible. - - The value returned by `memcpy' is the value of TO. - - Here is an example of how you might use `memcpy' to copy the - contents of an array: - - struct foo *oldarray, *newarray; - int arraysize; - ... - memcpy (new, old, arraysize * sizeof (struct foo)); - - - Function: wchar_t * wmemcpy (wchar_t *restrict WTO, const wchar_t - *restruct WFROM, size_t SIZE) - The `wmemcpy' function copies SIZE wide characters from the object - beginning at WFROM into the object beginning at WTO. The behavior - of this function is undefined if the two arrays WTO and WFROM - overlap; use `wmemmove' instead if overlapping is possible. - - The following is a possible implementation of `wmemcpy' but there - are more optimizations possible. - - wchar_t * - wmemcpy (wchar_t *restrict wto, const wchar_t *restrict wfrom, - size_t size) - { - return (wchar_t *) memcpy (wto, wfrom, size * sizeof (wchar_t)); - } - - The value returned by `wmemcpy' is the value of WTO. - - This function was introduced in Amendment 1 to ISO C90. - - - Function: void * mempcpy (void *restrict TO, const void *restrict - FROM, size_t SIZE) - The `mempcpy' function is nearly identical to the `memcpy' - function. It copies SIZE bytes from the object beginning at - `from' into the object pointed to by TO. But instead of returning - the value of TO it returns a pointer to the byte following the - last written byte in the object beginning at TO. I.e., the value - is `((void *) ((char *) TO + SIZE))'. - - This function is useful in situations where a number of objects - shall be copied to consecutive memory positions. - - void * - combine (void *o1, size_t s1, void *o2, size_t s2) - { - void *result = malloc (s1 + s2); - if (result != NULL) - mempcpy (mempcpy (result, o1, s1), o2, s2); - return result; - } - - This function is a GNU extension. - - - Function: wchar_t * wmempcpy (wchar_t *restrict WTO, const wchar_t - *restrict WFROM, size_t SIZE) - The `wmempcpy' function is nearly identical to the `wmemcpy' - function.

In the case of - overlap, `memmove' is careful to copy the original values of the - bytes in the block at FROM, including those bytes which also - belong to the block at TO. - - The value returned by `memmove' is the value of TO. - - - Function: wchar_t * wmemmove (wchar *WTO, const wchar_t *WFROM, - size_t SIZE) - `wmemmove' copies the SIZE wide characters at WFROM into the SIZE - wide characters at WTO, even if those two blocks of space overlap. - In the case of overlap, `memmove' is careful to copy the original - values of the wide characters in the block at WFROM, including - those wide characters which also belong to the block at WTO. - - The following is a possible implementation of `wmemcpy' but there - are more optimizations possible. - - wchar_t * - wmempcpy (wchar_t *restrict wto, const wchar_t *restrict wfrom, - size_t size) - { - return (wchar_t *) mempcpy (wto, wfrom, size * sizeof (wchar_t)); - } - - The value returned by `wmemmove' is the value of WTO. - - This function is a GNU extension. - - - Function: void * memccpy (void *restrict TO, const void *restrict - FROM, int C, size_t SIZE) - This function copies no more than SIZE bytes from FROM to TO, - stopping if a byte matching C is found. The return value is a - pointer into TO one byte past where C was copied, or a null - pointer if no byte matching C appeared in the first SIZE bytes of - FROM. - - - Function: void * memset (void *BLOCK, int C, size_t SIZE) - This function copies the value of C (converted to an `unsigned - char') into each of the first SIZE bytes of the object beginning - at BLOCK. It returns the value of BLOCK. - - - Function: wchar_t * wmemset (wchar_t *BLOCK, wchar_t WC, size_t SIZE) - This function copies the value of WC into each of the first SIZE - wide characters of the object beginning at BLOCK. It returns the - value of BLOCK. - - - Function: char * strcpy (char *restrict TO, const char *restrict - FROM) - This copies characters from the string FROM (up to and including - the terminating null character) into the string TO.

In this case, SIZE may be large, and when it is, - `strncpy' will waste a considerable amount of time copying null - characters. - - - Function: wchar_t * wcsncpy (wchar_t *restrict WTO, const wchar_t - *restrict WFROM, size_t SIZE) - This function is similar to `wcscpy' but always copies exactly - SIZE wide characters into WTO. - - If the length of WFROM is more than SIZE, then `wcsncpy' copies - just the first SIZE wide characters. Note that in this case there - is no null terminator written into WTO. - - If the length of WFROM is less than SIZE, then `wcsncpy' copies - all of WFROM, followed by enough null wide characters to add up to - SIZE wide characters in all.

The string is allocated using `malloc'; see - *Note Unconstrained Allocation::. If `malloc' cannot allocate - space for the new string, `strdup' returns a null pointer. - Otherwise it returns a pointer to the new string. - - - Function: wchar_t * wcsdup (const wchar_t *WS) - This function copies the null-terminated wide character string WS - into a newly allocated string. The string is allocated using - `malloc'; see *Note Unconstrained Allocation::. If `malloc' - cannot allocate space for the new string, `wcsdup' returns a null - pointer. Otherwise it returns a pointer to the new wide character - string. - - This function is a GNU extension. - - - Function: char * strndup (const char *S, size_t SIZE) - This function is similar to `strdup' but always copies at most - SIZE characters into the newly allocated string. - - If the length of S is more than SIZE, then `strndup' copies just - the first SIZE characters and adds a closing null terminator. - Otherwise all characters are copied and the string is terminated. - - This function is different to `strncpy' in that it always - terminates the destination string. - - `strndup' is a GNU extension. - - - Function: char * stpcpy (char *restrict TO, const char *restrict - FROM) - This function is like `strcpy', except that it returns a pointer to - the end of the string TO (that is, the address of the terminating - null character `to + strlen (from)') rather than the beginning. - - For example, this program uses `stpcpy' to concatenate `foo' and - `bar' to produce `foobar', which it then prints. - - #include - #include - - int - main (void) - { - char buffer[10]; - char *to = buffer; - to = stpcpy (to, "foo"); - to = stpcpy (to, "bar"); - puts (buffer); - return 0; - } - - This function is not part of the ISO or POSIX standards, and is not - customary on Unix systems, but we did not invent it either. - Perhaps it comes from MS-DOG. - - Its behavior is undefined if the strings overlap. The function is - declared in `string.h'. - - - Function: wchar_t * wcpcpy (wchar_t *restrict WTO, const wchar_t - *restrict WFROM) - This function is like `wcscpy', except that it returns a pointer to - the end of the string WTO (that is, the address of the terminating - null character `wto + strlen (wfrom)') rather than the beginning. - - This function is not part of ISO or POSIX but was found useful - while developing the GNU C Library itself. - - The behavior of `wcpcpy' is undefined if the strings overlap. - - `wcpcpy' is a GNU extension and is declared in `wchar.h'. - - - Function: char * stpncpy (char *restrict TO, const char *restrict - FROM, size_t SIZE) - This function is similar to `stpcpy' but copies always exactly - SIZE characters into TO. - - If the length of FROM is more then SIZE, then `stpncpy' copies - just the first SIZE characters and returns a pointer to the - character directly following the one which was copied last. Note - that in this case there is no null terminator written into TO. - - If the length of FROM is less than SIZE, then `stpncpy' copies all - of FROM, followed by enough null characters to add up to SIZE - characters in all. This behavior is rarely useful, but it is - implemented to be useful in contexts where this behavior of the - `strncpy' is used. `stpncpy' returns a pointer to the _first_ - written null character. - - This function is not part of ISO or POSIX but was found useful - while developing the GNU C Library itself. - - Its behavior is undefined if the strings overlap. The function is - declared in `string.h'. - - - Function: wchar_t * wcpncpy (wchar_t *restrict WTO, const wchar_t - *restrict WFROM, size_t SIZE) - This function is similar to `wcpcpy' but copies always exactly - WSIZE characters into WTO. - - If the length of WFROM is more then SIZE, then `wcpncpy' copies - just the first SIZE wide characters and returns a pointer to the - wide character directly following the one which was copied last. - Note that in this case there is no null terminator written into - WTO. - - If the length of WFROM is less than SIZE, then `wcpncpy' copies - all of WFROM, followed by enough null characters to add up to SIZE - characters in all. This behavior is rarely useful, but it is - implemented to be useful in contexts where this behavior of the - `wcsncpy' is used. `wcpncpy' returns a pointer to the _first_ - written null character. - - This function is not part of ISO or POSIX but was found useful - while developing the GNU C Library itself. - - Its behavior is undefined if the strings overlap. - - `wcpncpy' is a GNU extension and is declared in `wchar.h'. - - - Macro: char * strdupa (const char *S) - This macro is similar to `strdup' but allocates the new string - using `alloca' instead of `malloc' (*note Variable Size - Automatic::). This means of course the returned string has the - same limitations as any block of memory allocated using `alloca'. - - For obvious reasons `strdupa' is implemented only as a macro; you - cannot get the address of this function. Despite this limitation - it is a useful function. The following code shows a situation - where using `malloc' would be a lot more expensive. - - #include - #include - #include - - const char path[] = _PATH_STDPATH; - - int - main (void) - { - char *wr_path = strdupa (path); - char *cp = strtok (wr_path, ":"); - - while (cp != NULL) - { - puts (cp); - cp = strtok (NULL, ":"); - } - return 0; - } - - Please note that calling `strtok' using PATH directly is invalid. - It is also not allowed to call `strdupa' in the argument list of - `strtok' since `strdupa' uses `alloca' (*note Variable Size - Automatic::) can interfere with the parameter passing. - - This function is only available if GNU CC is used. - - - Macro: char * strndupa (const char *S, size_t SIZE) - This function is similar to `strndup' but like `strdupa' it - allocates the new string using `alloca' *note Variable Size - Automatic::. The same advantages and limitations of `strdupa' are - valid for `strndupa', too. - - This function is implemented only as a macro, just like `strdupa'. - Just as `strdupa' this macro also must not be used inside the - parameter list in a function call. - - `strndupa' is only available if GNU CC is used. - - - Function: char * strcat (char *restrict TO, const char *restrict - FROM) - The `strcat' function is similar to `strcpy', except that the - characters from FROM are concatenated or appended to the end of - TO, instead of overwriting it. That is, the first character from - FROM overwrites the null character marking the end of TO. - - An equivalent definition for `strcat' would be: - - char * - strcat (char *restrict to, const char *restrict from) - { - strcpy (to + strlen (to), from); - return to; - } - - This function has undefined results if the strings overlap. - - - Function: wchar_t * wcscat (wchar_t *restrict WTO, const wchar_t - *restrict WFROM) - The `wcscat' function is similar to `wcscpy', except that the - characters from WFROM are concatenated or appended to the end of - WTO, instead of overwriting it. That is, the first character from - WFROM overwrites the null character marking the end of WTO. - - An equivalent definition for `wcscat' would be: - - wchar_t * - wcscat (wchar_t *wto, const wchar_t *wfrom) - { - wcscpy (wto + wcslen (wto), wfrom); - return wto; - } - - This function has undefined results if the strings overlap. - - Programmers using the `strcat' or `wcscat' function (or the -following `strncat' or `wcsncar' functions for that matter) can easily -be recognized as lazy and reckless. In almost all situations the -lengths of the participating strings are known (it better should be -since how can one otherwise ensure the allocated size of the buffer is -sufficient?) Or at least, one could know them if one keeps track of the -results of the various function calls. But then it is very inefficient -to use `strcat'/`wcscat'. A lot of time is wasted finding the end of -the destination string so that the actual copying can start. This is a -common example: - - /* This function concatenates arbitrarily many strings. The last - parameter must be `NULL'. */ - char * - concat (const char *str, ...) - { - va_list ap, ap2; - size_t total = 1; - const char *s; - char *result; - - va_start (ap, str); - /* Actually `va_copy', but this is the name more gcc versions - understand. */ - __va_copy (ap2, ap); - - /* Determine how much space we need. */ - for (s = str; s != NULL; s = va_arg (ap, const char *)) - total += strlen (s); - - va_end (ap); - - result = (char *) malloc (total); - if (result != NULL) - { - result[0] = '\0'; - - /* Copy the strings. */ - for (s = str; s != NULL; s = va_arg (ap2, const char *)) - strcat (result, s); - } - - va_end (ap2); - - return result; - } - - This looks quite simple, especially the second loop where the strings -are actually copied. But these innocent lines hide a major performance -penalty. Just imagine that ten strings of 100 bytes each have to be -concatenated. For the second string we search the already stored 100 -bytes for the end of the string so that we can append the next string. -For all strings in total the comparisons necessary to find the end of -the intermediate results sums up to 5500! If we combine the copying -with the search for the allocation we can write this function more -efficient: - - char * - concat (const char *str, ...) - { - va_list ap; - size_t allocated = 100; - char *result = (char *) malloc (allocated); - char *wp; - - if (allocated != NULL) - { - char *newp; - - va_start (ap, atr); - - wp = result; - for (s = str; s != NULL; s = va_arg (ap, const char *)) - { - size_t len = strlen (s); - - /* Resize the allocated memory if necessary. */ - if (wp + len + 1 > result + allocated) - { - allocated = (allocated + len) * 2; - newp = (char *) realloc (result, allocated); - if (newp == NULL) - { - free (result); - return NULL; - } - wp = newp + (wp - result); - result = newp; - } - - wp = mempcpy (wp, s, len); - } - - /* Terminate the result string. */ - *wp++ = '\0'; - - /* Resize memory to the optimal size. */ - newp = realloc (result, wp - result); - if (newp != NULL) - result = newp; - - va_end (ap); - } - - return result; - } - - With a bit more knowledge about the input strings one could fine-tune -the memory allocation. The difference we are pointing to here is that -we don't use `strcat' anymore. We always keep track of the length of -the current intermediate result so we can safe us the search for the -end of the string and use `mempcpy'. Please note that we also don't -use `stpcpy' which might seem more natural since we handle with -strings. But this is not necessary since we already know the length of -the string and therefore can use the faster memory copying function. -The example would work for wide characters the same way. - - Whenever a programmer feels the need to use `strcat' she or he -should think twice and look through the program whether the code cannot -be rewritten to take advantage of already calculated results. Again: it -is almost always unnecessary to use `strcat'. - - - Function: char * strncat (char *restrict TO, const char *restrict - FROM, size_t SIZE) - This function is like `strcat' except that not more than SIZE - characters from FROM are appended to the end of TO. A single null - character is also always appended to TO, so the total allocated - size of TO must be at least `SIZE + 1' bytes longer than its - initial length. - - The `strncat' function could be implemented like this: - - char * - strncat (char *to, const char *from, size_t size) - { - to[strlen (to) + size] = '\0'; - strncpy (to + strlen (to), from, size); - return to; - } - - The behavior of `strncat' is undefined if the strings overlap. - - - Function: wchar_t * wcsncat (wchar_t *restrict WTO, const wchar_t - *restrict WFROM, size_t SIZE) - This function is like `wcscat' except that not more than SIZE - characters from FROM are appended to the end of TO. A single null - character is also always appended to TO, so the total allocated - size of TO must be at least `SIZE + 1' bytes longer than its - initial length. - - The `wcsncat' function could be implemented like this: - - wchar_t * - wcsncat (wchar_t *restrict wto, const wchar_t *restrict wfrom, - size_t size) - { - wto[wcslen (to) + size] = L'\0'; - wcsncpy (wto + wcslen (wto), wfrom, size); - return wto; - } - - The behavior of `wcsncat' is undefined if the strings overlap. - - Here is an example showing the use of `strncpy' and `strncat' (the -wide character version is equivalent). Notice how, in the call to -`strncat', the SIZE parameter is computed to avoid overflowing the -character array `buffer'. - - #include - #include - - #define SIZE 10 - - static char buffer[SIZE]; - - main () - { - strncpy (buffer, "hello", SIZE); - puts (buffer); - strncat (buffer, ", world", SIZE - strlen (buffer) - 1); - puts (buffer); - } - -The output produced by this program looks like: - - hello - hello, wo - - - Function: void bcopy (const void *FROM, void *TO, size_t SIZE) - This is a partially obsolete alternative for `memmove', derived - from BSD. Note that it is not quite equivalent to `memmove', - because the arguments are not in the same order and there is no - return value. - - - Function: void bzero (void *BLOCK, size_t SIZE) - This is a partially obsolete alternative for `memset', derived from - BSD. Note that it is not as general as `memset', because the only - value it can store is zero. - - -File: libc.info, Node: String/Array Comparison, Next: Collation Functions, Prev: Copying and Concatenation, Up: String and Array Utilities - -String/Array Comparison -======================= - - You can use the functions in this section to perform comparisons on -the contents of strings and arrays. As well as checking for equality, -these functions can also be used as the ordering functions for sorting -operations. *Note Searching and Sorting::, for an example of this. - - Unlike most comparison operations in C, the string comparison -functions return a nonzero value if the strings are _not_ equivalent -rather than if they are. The sign of the value indicates the relative -ordering of the first characters in the strings that are not -equivalent: a negative value indicates that the first string is "less" -than the second, while a positive value indicates that the first string -is "greater". - - The most common use of these functions is to check only for equality. -This is canonically done with an expression like `! strcmp (s1, s2)'. - - All of these functions are declared in the header file `string.h'. - - - Function: int memcmp (const void *A1, const void *A2, size_t SIZE) - The function `memcmp' compares the SIZE bytes of memory beginning - at A1 against the SIZE bytes of memory beginning at A2. The value - returned has the same sign as the difference between the first - differing pair of bytes (interpreted as `unsigned char' objects, - then promoted to `int'). - - If the contents of the two blocks are equal, `memcmp' returns `0'. - - - Function: int wmemcmp (const wchar_t *A1, const wchar_t *A2, size_t - SIZE) - The function `wmemcmp' compares the SIZE wide characters beginning - at A1 against the SIZE wide characters beginning at A2. The value - returned is smaller than or larger than zero depending on whether - the first differing wide character is A1 is smaller or larger than - the corresponding character in A2. - - If the contents of the two blocks are equal, `wmemcmp' returns `0'. - - On arbitrary arrays, the `memcmp' function is mostly useful for -testing equality. It usually isn't meaningful to do byte-wise ordering -comparisons on arrays of things other than bytes. For example, a -byte-wise comparison on the bytes that make up floating-point numbers -isn't likely to tell you anything about the relationship between the -values of the floating-point numbers. - - `wmemcmp' is really only useful to compare arrays of type `wchar_t' -since the function looks at `sizeof (wchar_t)' bytes at a time and this -number of bytes is system dependent. - - You should also be careful about using `memcmp' to compare objects -that can contain "holes", such as the padding inserted into structure -objects to enforce alignment requirements, extra space at the end of -unions, and extra characters at the ends of strings whose length is less -than their allocated size. The contents of these "holes" are -indeterminate and may cause strange behavior when performing byte-wise -comparisons. For more predictable results, perform an explicit -component-wise comparison. - - For example, given a structure type definition like: - - struct foo - { - unsigned char tag; - union - { - double f; - long i; - char *p; - } value; - }; - -you are better off writing a specialized comparison function to compare -`struct foo' objects instead of comparing them with `memcmp'. - - - Function: int strcmp (const char *S1, const char *S2) - The `strcmp' function compares the string S1 against S2, returning - a value that has the same sign as the difference between the first - differing pair of characters (interpreted as `unsigned char' - objects, then promoted to `int'). - - If the two strings are equal, `strcmp' returns `0'. - - A consequence of the ordering used by `strcmp' is that if S1 is an - initial substring of S2, then S1 is considered to be "less than" - S2. - - `strcmp' does not take sorting conventions of the language the - strings are written in into account. To get that one has to use - `strcoll'. - - - Function: int wcscmp (const wchar_t *WS1, const wchar_t *WS2) - The `wcscmp' function compares the wide character string WS1 - against WS2. The value returned is smaller than or larger than - zero depending on whether the first differing wide character is - WS1 is smaller or larger than the corresponding character in WS2. - - If the two strings are equal, `wcscmp' returns `0'. - - A consequence of the ordering used by `wcscmp' is that if WS1 is - an initial substring of WS2, then WS1 is considered to be "less - than" WS2. - - `wcscmp' does not take sorting conventions of the language the - strings are written in into account. To get that one has to use - `wcscoll'. - - - Function: int strcasecmp (const char *S1, const char *S2) - This function is like `strcmp', except that differences in case are - ignored. How uppercase and lowercase characters are related is - determined by the currently selected locale. In the standard `"C"' - locale the characters A" and a" do not match but in a locale which - regards these characters as parts of the alphabet they do match. - - `strcasecmp' is derived from BSD. - - - Function: int wcscasecmp (const wchar_t *WS1, const wchar_T *WS2) - This function is like `wcscmp', except that differences in case are - ignored. How uppercase and lowercase characters are related is - determined by the currently selected locale. In the standard `"C"' - locale the characters A" and a" do not match but in a locale which - regards these characters as parts of the alphabet they do match. - - `wcscasecmp' is a GNU extension. - - - Function: int strncmp (const char *S1, const char *S2, size_t SIZE) - This function is the similar to `strcmp', except that no more than - SIZE wide characters are compared. In other words, if the two - strings are the same in their first SIZE wide characters, the - return value is zero. - - - Function: int wcsncmp (const wchar_t *WS1, const wchar_t *WS2, - size_t SIZE) - This function is the similar to `wcscmp', except that no more than - SIZE wide characters are compared. In other words, if the two - strings are the same in their first SIZE wide characters, the - return value is zero. - - - Function: int strncasecmp (const char *S1, const char *S2, size_t N) - This function is like `strncmp', except that differences in case - are ignored. Like `strcasecmp', it is locale dependent how - uppercase and lowercase characters are related. - - `strncasecmp' is a GNU extension. - - - Function: int wcsncasecmp (const wchar_t *WS1, const wchar_t *S2, - size_t N) - This function is like `wcsncmp', except that differences in case - are ignored. Like `wcscasecmp', it is locale dependent how - uppercase and lowercase characters are related. - - `wcsncasecmp' is a GNU extension. - - Here are some examples showing the use of `strcmp' and `strncmp' -(equivalent examples can be constructed for the wide character -functions). These examples assume the use of the ASCII character set. -(If some other character set--say, EBCDIC--is used instead, then the -glyphs are associated with different numeric codes, and the return -values and ordering may differ.) - - strcmp ("hello", "hello") - => 0 /* These two strings are the same. */ - strcmp ("hello", "Hello") - => 32 /* Comparisons are case-sensitive. */ - strcmp ("hello", "world") - => -15 /* The character `'h'' comes before `'w''. */ - strcmp ("hello", "hello, world") - => -44 /* Comparing a null character against a comma. */ - strncmp ("hello", "hello, world", 5) - => 0 /* The initial 5 characters are the same. */ - strncmp ("hello, world", "hello, stupid world!!!", 5) - => 0 /* The initial 5 characters are the same. */ - - - Function: int strverscmp (const char *S1, const char *S2) - The `strverscmp' function compares the string S1 against S2, - considering them as holding indices/version numbers. Return value - follows the same conventions as found in the `strverscmp' - function. In fact, if S1 and S2 contain no digits, `strverscmp' - behaves like `strcmp'. - - Basically, we compare strings normally (character by character), - until we find a digit in each string - then we enter a special - comparison mode, where each sequence of digits is taken as a - whole. If we reach the end of these two parts without noticing a - difference, we return to the standard comparison mode. There are - two types of numeric parts: "integral" and "fractional" (those - begin with a '0'). The types of the numeric parts affect the way - we sort them: - - * integral/integral: we compare values as you would expect. - - * fractional/integral: the fractional part is less than the - integral one. Again, no surprise. - - * fractional/fractional: the things become a bit more complex. - If the common prefix contains only leading zeroes, the - longest part is less than the other one; else the comparison - behaves normally. - - strverscmp ("no digit", "no digit") - => 0 /* same behavior as strcmp. */ - strverscmp ("item#99", "item#100") - => <0 /* same prefix, but 99 < 100. */ - strverscmp ("alpha1", "alpha001") - => >0 /* fractional part inferior to integral one. */ - strverscmp ("part1_f012", "part1_f01") - => >0 /* two fractional parts. */ - strverscmp ("foo.009", "foo.0") - => <0 /* idem, but with leading zeroes only. */ - - This function is especially useful when dealing with filename - sorting, because filenames frequently hold indices/version numbers. - - `strverscmp' is a GNU extension. - - - Function: int bcmp (const void *A1, const void *A2, size_t SIZE) - This is an obsolete alias for `memcmp', derived from BSD. - - -File: libc.info, Node: Collation Functions, Next: Search Functions, Prev: String/Array Comparison, Up: String and Array Utilities - -Collation Functions -=================== - - In some locales, the conventions for lexicographic ordering differ -from the strict numeric ordering of character codes. For example, in -Spanish most glyphs with diacritical marks such as accents are not -considered distinct letters for the purposes of collation. On the -other hand, the two-character sequence `ll' is treated as a single -letter that is collated immediately after `l'. - - You can use the functions `strcoll' and `strxfrm' (declared in the -headers file `string.h') and `wcscoll' and `wcsxfrm' (declared in the -headers file `wchar') to compare strings using a collation ordering -appropriate for the current locale. The locale used by these functions -in particular can be specified by setting the locale for the -`LC_COLLATE' category; see *Note Locales::. - - In the standard C locale, the collation sequence for `strcoll' is -the same as that for `strcmp'. Similarly, `wcscoll' and `wcscmp' are -the same in this situation. - - Effectively, the way these functions work is by applying a mapping to -transform the characters in a string to a byte sequence that represents -the string's position in the collating sequence of the current locale. -Comparing two such byte sequences in a simple fashion is equivalent to -comparing the strings with the locale's collating sequence. - - The functions `strcoll' and `wcscoll' perform this translation -implicitly, in order to do one comparison. By contrast, `strxfrm' and -`wcsxfrm' perform the mapping explicitly. If you are making multiple -comparisons using the same string or set of strings, it is likely to be -more efficient to use `strxfrm' or `wcsxfrm' to transform all the -strings just once, and subsequently compare the transformed strings -with `strcmp' or `wcscmp'. - - - Function: int strcoll (const char *S1, const char *S2) - The `strcoll' function is similar to `strcmp' but uses the - collating sequence of the current locale for collation (the - `LC_COLLATE' locale). - - - Function: int wcscoll (const wchar_t *WS1, const wchar_t *WS2) - The `wcscoll' function is similar to `wcscmp' but uses the - collating sequence of the current locale for collation (the - `LC_COLLATE' locale). - - Here is an example of sorting an array of strings, using `strcoll' -to compare them. The actual sort algorithm is not written here; it -comes from `qsort' (*note Array Sort Function::). The job of the code -shown here is to say how to compare the strings while sorting them. -(Later on in this section, we will show a way to do this more -efficiently using `strxfrm'.) - - /* This is the comparison function used with `qsort'. */ - - int - compare_elements (char **p1, char **p2) - { - return strcoll (*p1, *p2); - } - - /* This is the entry point--the function to sort - strings using the locale's collating sequence. */ - - void - sort_strings (char **array, int nstrings) - { - /* Sort `temp_array' by comparing the strings. */ - qsort (array, nstrings, - sizeof (char *), compare_elements); - } - - - Function: size_t strxfrm (char *restrict TO, const char *restrict - FROM, size_t SIZE) - The function `strxfrm' transforms the string FROM using the - collation transformation determined by the locale currently - selected for collation, and stores the transformed string in the - array TO. Up to SIZE characters (including a terminating null - character) are stored. - - The behavior is undefined if the strings TO and FROM overlap; see - *Note Copying and Concatenation::. - - The return value is the length of the entire transformed string. - This value is not affected by the value of SIZE, but if it is - greater or equal than SIZE, it means that the transformed string - did not entirely fit in the array TO. In this case, only as much - of the string as actually fits was stored. To get the whole - transformed string, call `strxfrm' again with a bigger output - array. - - The transformed string may be longer than the original string, and - it may also be shorter. - - If SIZE is zero, no characters are stored in TO. In this case, - `strxfrm' simply returns the number of characters that would be - the length of the transformed string. This is useful for - determining what size the allocated array should be. It does not - matter what TO is if SIZE is zero; TO may even be a null pointer. - - - Function: size_t wcsxfrm (wchar_t *restrict WTO, const wchar_t - *WFROM, size_t SIZE) - The function `wcsxfrm' transforms wide character string WFROM - using the collation transformation determined by the locale - currently selected for collation, and stores the transformed - string in the array WTO. Up to SIZE wide characters (including a - terminating null character) are stored. - - The behavior is undefined if the strings WTO and WFROM overlap; - see *Note Copying and Concatenation::. - - The return value is the length of the entire transformed wide - character string. This value is not affected by the value of - SIZE, but if it is greater or equal than SIZE, it means that the - transformed wide character string did not entirely fit in the - array WTO. In this case, only as much of the wide character - string as actually fits was stored. To get the whole transformed - wide character string, call `wcsxfrm' again with a bigger output - array. - - The transformed wide character string may be longer than the - original wide character string, and it may also be shorter. - - If SIZE is zero, no characters are stored in TO. In this case, - `wcsxfrm' simply returns the number of wide characters that would - be the length of the transformed wide character string. This is - useful for determining what size the allocated array should be - (remember to multiply with `sizeof (wchar_t)'). It does not - matter what WTO is if SIZE is zero; WTO may even be a null pointer. - - Here is an example of how you can use `strxfrm' when you plan to do -many comparisons. It does the same thing as the previous example, but -much faster, because it has to transform each string only once, no -matter how many times it is compared with other strings. Even the time -needed to allocate and free storage is much less than the time we save, -when there are many strings. - - struct sorter { char *input; char *transformed; }; - - /* This is the comparison function used with `qsort' - to sort an array of `struct sorter'. */ - - int - compare_elements (struct sorter *p1, struct sorter *p2) - { - return strcmp (p1->transformed, p2->transformed); - } - - /* This is the entry point--the function to sort - strings using the locale's collating sequence. */ - - void - sort_strings_fast (char **array, int nstrings) - { - struct sorter temp_array[nstrings]; - int i; - - /* Set up `temp_array'.

These functions are -declared in the header file `string.h'. - - - Function: void * memchr (const void *BLOCK, int C, size_t SIZE) - This function finds the first occurrence of the byte C (converted - to an `unsigned char') in the initial SIZE bytes of the object - beginning at BLOCK. The return value is a pointer to the located - byte, or a null pointer if no match was found. - - - Function: wchar_t * wmemchr (const wchar_t *BLOCK, wchar_t WC, - size_t SIZE) - This function finds the first occurrence of the wide character WC - in the initial SIZE wide characters of the object beginning at - BLOCK. The return value is a pointer to the located wide - character, or a null pointer if no match was found. - - - Function: void * rawmemchr (const void *BLOCK, int C) - Often the `memchr' function is used with the knowledge that the - byte C is available in the memory block specified by the - parameters. But this means that the SIZE parameter is not really - needed and that the tests performed with it at runtime (to check - whether the end of the block is reached) are not needed. - - The `rawmemchr' function exists for just this situation which is - surprisingly frequent. The interface is similar to `memchr' except - that the SIZE parameter is missing. The function will look beyond - the end of the block pointed to by BLOCK in case the programmer - made an error in assuming that the byte C is present in the block. - In this case the result is unspecified. Otherwise the return - value is a pointer to the located byte. - - This function is of special interest when looking for the end of a - string. Since all strings are terminated by a null byte a call - like - - rawmemchr (str, '\0') - - will never go beyond the end of the string. - - This function is a GNU extension. - - - Function: void * memrchr (const void *BLOCK, int C, size_t SIZE) - The function `memrchr' is like `memchr', except that it searches - backwards from the end of the block defined by BLOCK and SIZE - (instead of forwards from the front). - - - Function: char * strchr (const char *STRING, int C) - The `strchr' function finds the first occurrence of the character - C (converted to a `char') in the null-terminated string beginning - at STRING. The return value is a pointer to the located - character, or a null pointer if no match was found. - - For example, - strchr ("hello, world", 'l') - => "llo, world" - strchr ("hello, world", '?') - => NULL - - The terminating null character is considered to be part of the - string, so you can use this function get a pointer to the end of a - string by specifying a null character as the value of the C - argument. It would be better (but less portable) to use - `strchrnul' in this case, though. - - - Function: wchar_t * wcschr (const wchar_t *WSTRING, int WC) - The `wcschr' function finds the first occurrence of the wide - character WC in the null-terminated wide character string - beginning at WSTRING. The return value is a pointer to the - located wide character, or a null pointer if no match was found. - - The terminating null character is considered to be part of the wide - character string, so you can use this function get a pointer to - the end of a wide character string by specifying a null wude - character as the value of the WC argument. It would be better - (but less portable) to use `wcschrnul' in this case, though. - - - Function: char * strchrnul (const char *STRING, int C) - `strchrnul' is the same as `strchr' except that if it does not - find the character, it returns a pointer to string's terminating - null character rather than a null pointer. - - This function is a GNU extension. - - - Function: wchar_t * wcschrnul (const wchar_t *WSTRING, wchar_t WC) - `wcschrnul' is the same as `wcschr' except that if it does not - find the wide character, it returns a pointer to wide character - string's terminating null wide character rather than a null - pointer. - - This function is a GNU extension. - - One useful, but unusual, use of the `strchr' function is when one -wants to have a pointer pointing to the NUL byte terminating a string. -This is often written in this way: - - s += strlen (s); - -This is almost optimal but the addition operation duplicated a bit of -the work already done in the `strlen' function. A better solution is -this: - - s = strchr (s, '\0'); - - There is no restriction on the second parameter of `strchr' so it -could very well also be the NUL character. Those readers thinking very -hard about this might now point out that the `strchr' function is more -expensive than the `strlen' function since we have two abort criteria. -This is right. But in the GNU C library the implementation of `strchr' -is optimized in a special way so that `strchr' actually is faster. - - - Function: char * strrchr (const char *STRING, int C) - The function `strrchr' is like `strchr', except that it searches - backwards from the end of the string STRING (instead of forwards - from the front). - - For example, - strrchr ("hello, world", 'l') - => "ld" - - - Function: wchar_t * wcsrchr (const wchar_t *WSTRING, wchar_t C) - The function `wcsrchr' is like `wcschr', except that it searches - backwards from the end of the string WSTRING (instead of forwards - from the front). - - - Function: char * strstr (const char *HAYSTACK, const char *NEEDLE) - This is like `strchr', except that it searches HAYSTACK for a - substring NEEDLE rather than just a single character.

ARGV must be - pre-allocated with enough space to hold all the elements in ARGZ - plus the terminating `(char *)0' (`(argz_count (ARGZ, ARGZ_LEN) + - 1) * sizeof (char *)' bytes should be enough). Note that the - string pointers stored into ARGV point into ARGZ--they are not - copies--and so ARGZ must be copied if it will be changed while - ARGV is still active. This function is useful for passing the - elements in ARGZ to an exec function (*note Executing a File::). - - - Function: void argz_stringify (char *ARGZ, size_t LEN, int SEP) - The `argz_stringify' converts ARGZ into a normal string with the - elements separated by the character SEP, by replacing each `'\0'' - inside ARGZ (except the last one, which terminates the string) - with SEP. This is handy for printing ARGZ in a readable manner. - - - Function: error_t argz_add (char **ARGZ, size_t *ARGZ_LEN, const - char *STR) - The `argz_add' function adds the string STR to the end of the argz - vector `*ARGZ', and updates `*ARGZ' and `*ARGZ_LEN' accordingly. - - - Function: error_t argz_add_sep (char **ARGZ, size_t *ARGZ_LEN, const - char *STR, int DELIM) - The `argz_add_sep' function is similar to `argz_add', but STR is - split into separate elements in the result at occurrences of the - character DELIM.

Note that as destructive argz functions usually - reallocate their argz argument, pointers into argz vectors such as - ENTRY will then become invalid. - - - Function: error_t argz_insert (char **ARGZ, size_t *ARGZ_LEN, char - *BEFORE, const char *ENTRY) - The `argz_insert' function inserts the string ENTRY into the argz - vector `*ARGZ' at a point just before the existing element pointed - to by BEFORE, reallocating `*ARGZ' and updating `*ARGZ' and - `*ARGZ_LEN'. If BEFORE is `0', ENTRY is added to the end instead - (as if by `argz_add').

It returns a pointer - to the next element in ARGZ after the element ENTRY, or `0' if - there are no elements following ENTRY. If ENTRY is `0', the first - element of ARGZ is returned. - - This behavior suggests two styles of iteration: - - char *entry = 0; - while ((entry = argz_next (ARGZ, ARGZ_LEN, entry))) - ACTION; - - (the double parentheses are necessary to make some C compilers - shut up about what they consider a questionable `while'-test) and: - - char *entry; - for (entry = ARGZ; - entry; - entry = argz_next (ARGZ, ARGZ_LEN, entry)) - ACTION; - - Note that the latter depends on ARGZ having a value of `0' if it - is empty (rather than a pointer to an empty block of memory); this - invariant is maintained for argz vectors created by the functions - here. - - - Function: error_t argz_replace (char **ARGZ, size_t *ARGZ_LEN, - const char *STR, const char *WITH, unsigned *REPLACE_COUNT) - Replace any occurrences of the string STR in ARGZ with WITH, - reallocating ARGZ as necessary.

The remainder of this -section gives a few examples to help understand the design decisions -made while developing the functionality of the C library. - - A distinction we have to make right away is between internal and -external representation. "Internal representation" means the -representation used by a program while keeping the text in memory. -External representations are used when text is stored or transmitted -through some communication channel. Examples of external -representations include files waiting in a directory to be read and -parsed. - - Traditionally there has been no difference between the two -representations. It was equally comfortable and useful to use the same -single-byte representation internally and externally. This comfort -level decreases with more and larger character sets. - - One of the problems to overcome with the internal representation is -handling text that is externally encoded using different character -sets. Assume a program that reads two texts and compares them using -some metric. The comparison can be usefully done only if the texts are -internally kept in a common format. - - For such a common format (= character set) eight bits are certainly -no longer enough. So the smallest entity will have to grow: "wide -characters" will now be used. Instead of one byte per character, two or -four will be used instead. (Three are not good to address in memory and -more than four bytes seem not to be necessary). - - As shown in some other part of this manual, a completely new family -has been created of functions that can handle wide character texts in -memory. The most commonly used character sets for such internal wide -character representations are Unicode and ISO 10646 (also known as UCS -for Universal Character Set). Unicode was originally planned as a -16-bit character set; whereas, ISO 10646 was designed to be a 31-bit -large code space. The two standards are practically identical. They -have the same character repertoire and code table, but Unicode specifies -added semantics. At the moment, only characters in the first `0x10000' -code positions (the so-called Basic Multilingual Plane, BMP) have been -assigned, but the assignment of more specialized characters outside this -16-bit space is already in progress. A number of encodings have been -defined for Unicode and ISO 10646 characters: UCS-2 is a 16-bit word -that can only represent characters from the BMP, UCS-4 is a 32-bit word -than can represent any Unicode and ISO 10646 character, UTF-8 is an -ASCII compatible encoding where ASCII characters are represented by -ASCII bytes and non-ASCII characters by sequences of 2-6 non-ASCII -bytes, and finally UTF-16 is an extension of UCS-2 in which pairs of -certain UCS-2 words can be used to encode non-BMP characters up to -`0x10ffff'. - - To represent wide characters the `char' type is not suitable. For -this reason the ISO C standard introduces a new type that is designed -to keep one character of a wide character string. To maintain the -similarity there is also a type corresponding to `int' for those -functions that take a single wide character. - - - Data type: wchar_t - This data type is used as the base type for wide character strings. - In other words, arrays of objects of this type are the equivalent - of `char[]' for multibyte character strings. The type is defined - in `stddef.h'. - - The ISO C90 standard, where `wchar_t' was introduced, does not say - anything specific about the representation. It only requires that - this type is capable of storing all elements of the basic - character set. Therefore it would be legitimate to define - `wchar_t' as `char', which might make sense for embedded systems. - - But for GNU systems `wchar_t' is always 32 bits wide and, - therefore, capable of representing all UCS-4 values and, - therefore, covering all of ISO 10646. Some Unix systems define - `wchar_t' as a 16-bit type and thereby follow Unicode very - strictly. This definition is perfectly fine with the standard, - but it also means that to represent all characters from Unicode - and ISO 10646 one has to use UTF-16 surrogate characters, which is - in fact a multi-wide-character encoding. But resorting to - multi-wide-character encoding contradicts the purpose of the - `wchar_t' type. - - - Data type: wint_t - `wint_t' is a data type used for parameters and variables that - contain a single wide character. As the name suggests this type - is the equivalent of `int' when using the normal `char' strings. - The types `wchar_t' and `wint_t' often have the same - representation if their size is 32 bits wide but if `wchar_t' is - defined as `char' the type `wint_t' must be defined as `int' due - to the parameter promotion. - - This type is defined in `wchar.h' and was introduced in - Amendment 1 to ISO C90. - - As there are for the `char' data type macros are available for -specifying the minimum and maximum value representable in an object of -type `wchar_t'. - - - Macro: wint_t WCHAR_MIN - The macro `WCHAR_MIN' evaluates to the minimum value representable - by an object of type `wint_t'. - - This macro was introduced in Amendment 1 to ISO C90. - - - Macro: wint_t WCHAR_MAX - The macro `WCHAR_MAX' evaluates to the maximum value representable - by an object of type `wint_t'. - - This macro was introduced in Amendment 1 to ISO C90. - - Another special wide character value is the equivalent to `EOF'. - - - Macro: wint_t WEOF - The macro `WEOF' evaluates to a constant expression of type - `wint_t' whose value is different from any member of the extended - character set. - - `WEOF' need not be the same value as `EOF' and unlike `EOF' it - also need _not_ be negative. In other words, sloppy code like - - { - int c; - ... - while ((c = getc (fp)) < 0) - ... - } - - has to be rewritten to use `WEOF' explicitly when wide characters - are used: - - { - wint_t c; - ... - while ((c = wgetc (fp)) != WEOF) - ... - } - - This macro was introduced in Amendment 1 to ISO C90 and is defined - in `wchar.h'. - - These internal representations present problems when it comes to -storing and transmittal. Because each single wide character consists -of more than one byte, they are effected by byte-ordering. Thus, -machines with different endianesses would see different values when -accessing the same data. This byte ordering concern also applies for -communication protocols that are all byte-based and, thereforet require -that the sender has to decide about splitting the wide character in -bytes. A last (but not least important) point is that wide characters -often require more storage space than a customized byte-oriented -character set. - - For all the above reasons, an external encoding that is different -from the internal encoding is often used if the latter is UCS-2 or -UCS-4. The external encoding is byte-based and can be chosen -appropriately for the environment and for the texts to be handled. A -variety of different character sets can be used for this external -encoding (information that will not be exhaustively presented -here-instead, a description of the major groups will suffice). All of -the ASCII-based character sets fulfill one requirement: they are -"filesystem safe." This means that the character `'/'' is used in the -encoding _only_ to represent itself. Things are a bit different for -character sets like EBCDIC (Extended Binary Coded Decimal Interchange -Code, a character set family used by IBM), but if the operation system -does not understand EBCDIC directly the parameters-to-system calls have -to be converted first anyhow. - - * The simplest character sets are single-byte character sets. There - can be only up to 256 characters (for 8 bit character sets), which - is not sufficient to cover all languages but might be sufficient - to handle a specific text. Handling of a 8 bit character sets is - simple. This is not true for other kinds presented later, and - therefore, the application one uses might require the use of 8 bit - character sets. - - * The ISO 2022 standard defines a mechanism for extended character - sets where one character _can_ be represented by more than one - byte. This is achieved by associating a state with the text. - Characters that can be used to change the state can be embedded in - the text. Each byte in the text might have a different - interpretation in each state. The state might even influence - whether a given byte stands for a character on its own or whether - it has to be combined with some more bytes. - - In most uses of ISO 2022 the defined character sets do not allow - state changes that cover more than the next character. This has - the big advantage that whenever one can identify the beginning of - the byte sequence of a character one can interpret a text - correctly. Examples of character sets using this policy are the - various EUC character sets (used by Sun's operations systems, - EUC-JP, EUC-KR, EUC-TW, and EUC-CN) or Shift_JIS (SJIS, a Japanese - encoding). - - But there are also character sets using a state that is valid for - more than one character and has to be changed by another byte - sequence. Examples for this are ISO-2022-JP, ISO-2022-KR, and - ISO-2022-CN. - - * Early attempts to fix 8 bit character sets for other languages - using the Roman alphabet lead to character sets like ISO 6937. - Here bytes representing characters like the acute accent do not - produce output themselves: one has to combine them with other - characters to get the desired result. For example, the byte - sequence `0xc2 0x61' (non-spacing acute accent, followed by - lower-case `a') to get the "small a with acute" character. To - get the acute accent character on its own, one has to write `0xc2 - 0x20' (the non-spacing acute followed by a space). - - Character sets like ISO 6937 are used in some embedded systems such - as teletex. - - * Instead of converting the Unicode or ISO 10646 text used - internally, it is often also sufficient to simply use an encoding - different than UCS-2/UCS-4. The Unicode and ISO 10646 standards - even specify such an encoding: UTF-8. This encoding is able to - represent all of ISO 10646 31 bits in a byte string of length one - to six. - - There were a few other attempts to encode ISO 10646 such as UTF-7, - but UTF-8 is today the only encoding that should be used. In - fact, with any luck UTF-8 will soon be the only external encoding - that has to be supported. It proves to be universally usable and - its only disadvantage is that it favors Roman languages by making - the byte string representation of other scripts (Cyrillic, Greek, - Asian scripts) longer than necessary if using a specific character - set for these scripts. Methods like the Unicode compression - scheme can alleviate these problems. - - The question remaining is: how to select the character set or -encoding to use. The answer: you cannot decide about it yourself, it -is decided by the developers of the system or the majority of the -users. Since the goal is interoperability one has to use whatever the -other people one works with use. If there are no constraints, the -selection is based on the requirements the expected circle of users -will have. In other words, if a project is expected to be used in -only, say, Russia it is fine to use KOI8-R or a similar character set. -But if at the same time people from, say, Greece are participating one -should use a character set that allows all people to collaborate. - - The most widely useful solution seems to be: go with the most general -character set, namely ISO 10646. Use UTF-8 as the external encoding -and problems about users not being able to use their own language -adequately are a thing of the past. - - One final comment about the choice of the wide character -representation is necessary at this point. We have said above that the -natural choice is using Unicode or ISO 10646. This is not required, -but at least encouraged, by the ISO C standard. The standard defines -at least a macro `__STDC_ISO_10646__' that is only defined on systems -where the `wchar_t' type encodes ISO 10646 characters. If this symbol -is not defined one should avoid making assumptions about the wide -character representation. If the programmer uses only the functions -provided by the C library to handle wide character strings there should -be no compatibility problems with other systems. - - -File: libc.info, Node: Charset Function Overview, Next: Restartable multibyte conversion, Prev: Extended Char Intro, Up: Character Set Handling - -Overview about Character Handling Functions -=========================================== - - A Unix C library contains three different sets of functions in two -families to handle character set conversion. One of the function -families (the most commonly used) is specified in the ISO C90 standard -and, therefore, is portable even beyond the Unix world. Unfortunately -this family is the least useful one. These functions should be avoided -whenever possible, especially when developing libraries (as opposed to -applications). - - The second family of functions got introduced in the early Unix -standards (XPG2) and is still part of the latest and greatest Unix -standard: Unix 98. It is also the most powerful and useful set of -functions. But we will start with the functions defined in Amendment 1 -to ISO C90. - - -File: libc.info, Node: Restartable multibyte conversion, Next: Non-reentrant Conversion, Prev: Charset Function Overview, Up: Character Set Handling - -Restartable Multibyte Conversion Functions -========================================== - - The ISO C standard defines functions to convert strings from a -multibyte representation to wide character strings. There are a number -of peculiarities: - - * The character set assumed for the multibyte encoding is not - specified as an argument to the functions. Instead the character - set specified by the `LC_CTYPE' category of the current locale is - used; see *Note Locale Categories::. - - * The functions handling more than one character at a time require - NUL terminated strings as the argument (i.e., converting blocks of - text does not work unless one can add a NUL byte at an appropriate - place). The GNU C library contains some extensions to the - standard that allow specifying a size, but basically they also - expect terminated strings. - - Despite these limitations the ISO C functions can be used in many -contexts. In graphical user interfaces, for instance, it is not -uncommon to have functions that require text to be displayed in a wide -character string if the text is not simple ASCII. The text itself might -come from a file with translations and the user should decide about the -current locale, which determines the translation and therefore also the -external encoding used. In such a situation (and many others) the -functions described here are perfect. If more freedom while performing -the conversion is necessary take a look at the `iconv' functions (*note -Generic Charset Conversion::). - -* Menu: - -* Selecting the Conversion:: Selecting the conversion and its properties. -* Keeping the state:: Representing the state of the conversion. -* Converting a Character:: Converting Single Characters. -* Converting Strings:: Converting Multibyte and Wide Character - Strings. -* Multibyte Conversion Example:: A Complete Multibyte Conversion Example. - - -File: libc.info, Node: Selecting the Conversion, Next: Keeping the state, Up: Restartable multibyte conversion - -Selecting the conversion and its properties -------------------------------------------- - - We already said above that the currently selected locale for the -`LC_CTYPE' category decides about the conversion that is performed by -the functions we are about to describe. Each locale uses its own -character set (given as an argument to `localedef') and this is the one -assumed as the external multibyte encoding. The wide character -character set always is UCS-4, at least on GNU systems. - - A characteristic of each multibyte character set is the maximum -number of bytes that can be necessary to represent one character. This -information is quite important when writing code that uses the -conversion functions (as shown in the examples below). The ISO C -standard defines two macros that provide this information. - - - Macro: int MB_LEN_MAX - `MB_LEN_MAX' specifies the maximum number of bytes in the multibyte - sequence for a single character in any of the supported locales. - It is a compile-time constant and is defined in `limits.h'. - - - Macro: int MB_CUR_MAX - `MB_CUR_MAX' expands into a positive integer expression that is the - maximum number of bytes in a multibyte character in the current - locale. The value is never greater than `MB_LEN_MAX'. Unlike - `MB_LEN_MAX' this macro need not be a compile-time constant, and in - the GNU C library it is not. - - `MB_CUR_MAX' is defined in `stdlib.h'. - - Two different macros are necessary since strictly ISO C90 compilers -do not allow variable length array definitions, but still it is -desirable to avoid dynamic allocation. This incomplete piece of code -shows the problem: - - { - char buf[MB_LEN_MAX]; - ssize_t len = 0; - - while (! feof (fp)) - { - fread (&buf[len], 1, MB_CUR_MAX - len, fp); - /* ... process buf */ - len -= used; - } - } - - The code in the inner loop is expected to have always enough bytes in -the array BUF to convert one multibyte character. The array BUF has to -be sized statically since many compilers do not allow a variable size. -The `fread' call makes sure that `MB_CUR_MAX' bytes are always -available in BUF. Note that it isn't a problem if `MB_CUR_MAX' is not -a compile-time constant. - - -File: libc.info, Node: Keeping the state, Next: Converting a Character, Prev: Selecting the Conversion, Up: Restartable multibyte conversion - -Representing the state of the conversion ----------------------------------------- - - In the introduction of this chapter it was said that certain -character sets use a "stateful" encoding. That is, the encoded values -depend in some way on the previous bytes in the text. - - Since the conversion functions allow converting a text in more than -one step we must have a way to pass this information from one call of -the functions to another. - - - Data type: mbstate_t - A variable of type `mbstate_t' can contain all the information - about the "shift state" needed from one call to a conversion - function to another. - - `mbstate_t' is defined in `wchar.h'. It was introduced in - Amendment 1 to ISO C90. - - To use objects of type `mbstate_t' the programmer has to define such -objects (normally as local variables on the stack) and pass a pointer to -the object to the conversion functions. This way the conversion -function can update the object if the current multibyte character set -is stateful. - - There is no specific function or initializer to put the state object -in any specific state. The rules are that the object should always -represent the initial state before the first use, and this is achieved -by clearing the whole variable with code such as follows: - - { - mbstate_t state; - memset (&state, '\0', sizeof (state)); - /* from now on STATE can be used. */ - ... - } - - When using the conversion functions to generate output it is often -necessary to test whether the current state corresponds to the initial -state. This is necessary, for example, to decide whether to emit -escape sequences to set the state to the initial state at certain -sequence points. Communication protocols often require this. - - - Function: int mbsinit (const mbstate_t *PS) - The `mbsinit' function determines whether the state object pointed - to by PS is in the initial state. If PS is a null pointer or the - object is in the initial state the return value is nonzero. - Otherwise it is zero. - - `mbsinit' was introduced in Amendment 1 to ISO C90 and is declared - in `wchar.h'. - - Code using `mbsinit' often looks similar to this: - - { - mbstate_t state; - memset (&state, '\0', sizeof (state)); - /* Use STATE. */ - ... - if (! mbsinit (&state)) - { - /* Emit code to return to initial state. */ - const wchar_t empty[] = L""; - const wchar_t *srcp = empty; - wcsrtombs (outbuf, &srcp, outbuflen, &state); - } - ... - } - - The code to emit the escape sequence to get back to the initial -state is interesting. The `wcsrtombs' function can be used to -determine the necessary output code (*note Converting Strings::). -Please note that on GNU systems it is not necessary to perform this -extra action for the conversion from multibyte text to wide character -text since the wide character encoding is not stateful. But there is -nothing mentioned in any standard that prohibits making `wchar_t' using -a stateful encoding. - - -File: libc.info, Node: Converting a Character, Next: Converting Strings, Prev: Keeping the state, Up: Restartable multibyte conversion - -Converting Single Characters ----------------------------- - - The most fundamental of the conversion functions are those dealing -with single characters. Please note that this does not always mean -single bytes. But since there is very often a subset of the multibyte -character set that consists of single byte sequences, there are -functions to help with converting bytes. Frequently, ASCII is a subpart -of the multibyte character set. In such a scenario, each ASCII -character stands for itself, and all other characters have at least a -first byte that is beyond the range 0 to 127. - - - Function: wint_t btowc (int C) - The `btowc' function ("byte to wide character") converts a valid - single byte character C in the initial shift state into the wide - character equivalent using the conversion rules from the currently - selected locale of the `LC_CTYPE' category. - - If `(unsigned char) C' is no valid single byte multibyte character - or if C is `EOF', the function returns `WEOF'. - - Please note the restriction of C being tested for validity only in - the initial shift state. No `mbstate_t' object is used from which - the state information is taken, and the function also does not use - any static state. - - The `btowc' function was introduced in Amendment 1 to ISO C90 and - is declared in `wchar.h'. - - Despite the limitation that the single byte value always is -interpreted in the initial state this function is actually useful most -of the time. Most characters are either entirely single-byte character -sets or they are extension to ASCII. But then it is possible to write -code like this (not that this specific example is very useful): - - wchar_t * - itow (unsigned long int val) - { - static wchar_t buf[30]; - wchar_t *wcp = &buf[29]; - *wcp = L'\0'; - while (val != 0) - { - *--wcp = btowc ('0' + val % 10); - val /= 10; - } - if (wcp == &buf[29]) - *--wcp = L'0'; - return wcp; - } - - Why is it necessary to use such a complicated implementation and not -simply cast `'0' + val % 10' to a wide character? The answer is that -there is no guarantee that one can perform this kind of arithmetic on -the character of the character set used for `wchar_t' representation. -In other situations the bytes are not constant at compile time and so -the compiler cannot do the work. In situations like this it is -necessary `btowc'. - -There also is a function for the conversion in the other direction. - - - Function: int wctob (wint_t C) - The `wctob' function ("wide character to byte") takes as the - parameter a valid wide character. If the multibyte representation - for this character in the initial state is exactly one byte long, - the return value of this function is this character. Otherwise - the return value is `EOF'. - - `wctob' was introduced in Amendment 1 to ISO C90 and is declared - in `wchar.h'. - - There are more general functions to convert single character from -multibyte representation to wide characters and vice versa. These -functions pose no limit on the length of the multibyte representation -and they also do not require it to be in the initial state. - - - Function: size_t mbrtowc (wchar_t *restrict PWC, const char - *restrict S, size_t N, mbstate_t *restrict PS) - The `mbrtowc' function ("multibyte restartable to wide character") - converts the next multibyte character in the string pointed to by - S into a wide character and stores it in the wide character string - pointed to by PWC. The conversion is performed according to the - locale currently selected for the `LC_CTYPE' category. If the - conversion for the character set used in the locale requires a - state, the multibyte string is interpreted in the state - represented by the object pointed to by PS. If PS is a null - pointer, a static, internal state variable used only by the - `mbrtowc' function is used. - - If the next multibyte character corresponds to the NUL wide - character, the return value of the function is 0 and the state - object is afterwards in the initial state. If the next N or fewer - bytes form a correct multibyte character, the return value is the - number of bytes starting from S that form the multibyte character. - The conversion state is updated according to the bytes consumed - in the conversion. In both cases the wide character (either the - `L'\0'' or the one found in the conversion) is stored in the - string pointed to by PWC if PWC is not null. - - If the first N bytes of the multibyte string possibly form a valid - multibyte character but there are more than N bytes needed to - complete it, the return value of the function is `(size_t) -2' and - no value is stored. Please note that this can happen even if N - has a value greater than or equal to `MB_CUR_MAX' since the input - might contain redundant shift sequences. - - If the first `n' bytes of the multibyte string cannot possibly form - a valid multibyte character, no value is stored, the global - variable `errno' is set to the value `EILSEQ', and the function - returns `(size_t) -1'. The conversion state is afterwards - undefined. - - `mbrtowc' was introduced in Amendment 1 to ISO C90 and is declared - in `wchar.h'. - - Use of `mbrtowc' is straightforward. A function that copies a -multibyte string into a wide character string while at the same time -converting all lowercase characters into uppercase could look like this -(this is not the final version, just an example; it has no error -checking, and sometimes leaks memory): - - wchar_t * - mbstouwcs (const char *s) - { - size_t len = strlen (s); - wchar_t *result = malloc ((len + 1) * sizeof (wchar_t)); - wchar_t *wcp = result; - wchar_t tmp[1]; - mbstate_t state; - size_t nbytes; - - memset (&state, '\0', sizeof (state)); - while ((nbytes = mbrtowc (tmp, s, len, &state)) > 0) - { - if (nbytes >= (size_t) -2) - /* Invalid input string. */ - return NULL; - *result++ = towupper (tmp[0]); - len -= nbytes; - s += nbytes; - } - return result; - } - - The use of `mbrtowc' should be clear. A single wide character is -stored in `TMP[0]', and the number of consumed bytes is stored in the -variable NBYTES. If the conversion is successful, the uppercase -variant of the wide character is stored in the RESULT array and the -pointer to the input string and the number of available bytes is -adjusted. - - The only non-obvious thing about `mbrtowc' might be the way memory -is allocated for the result. The above code uses the fact that there -can never be more wide characters in the converted results than there -are bytes in the multibyte input string. This method yields a -pessimistic guess about the size of the result, and if many wide -character strings have to be constructed this way or if the strings are -long, the extra memory required to be allocated because the input -string contains multibyte characters might be significant. The -allocated memory block can be resized to the correct size before -returning it, but a better solution might be to allocate just the right -amount of space for the result right away. Unfortunately there is no -function to compute the length of the wide character string directly -from the multibyte string. There is, however, a function that does -part of the work. - - - Function: size_t mbrlen (const char *restrict S, size_t N, mbstate_t - *PS) - The `mbrlen' function ("multibyte restartable length") computes - the number of at most N bytes starting at S, which form the next - valid and complete multibyte character. - - If the next multibyte character corresponds to the NUL wide - character, the return value is 0. If the next N bytes form a valid - multibyte character, the number of bytes belonging to this - multibyte character byte sequence is returned. - - If the the first N bytes possibly form a valid multibyte character - but the character is incomplete, the return value is `(size_t) - -2'. Otherwise the multibyte character sequence is invalid and - the return value is `(size_t) -1'. - - The multibyte sequence is interpreted in the state represented by - the object pointed to by PS. If PS is a null pointer, a state - object local to `mbrlen' is used. - - `mbrlen' was introduced in Amendment 1 to ISO C90 and is declared - in `wchar.h'. - - The attentive reader now will note that `mbrlen' can be implemented -as - - mbrtowc (NULL, s, n, ps != NULL ? ps : &internal) - - This is true and in fact is mentioned in the official specification. -How can this function be used to determine the length of the wide -character string created from a multibyte character string? It is not -directly usable, but we can define a function `mbslen' using it: - - size_t - mbslen (const char *s) - { - mbstate_t state; - size_t result = 0; - size_t nbytes; - memset (&state, '\0', sizeof (state)); - while ((nbytes = mbrlen (s, MB_LEN_MAX, &state)) > 0) - { - if (nbytes >= (size_t) -2) - /* Something is wrong. */ - return (size_t) -1; - s += nbytes; - ++result; - } - return result; - } - - This function simply calls `mbrlen' for each multibyte character in -the string and counts the number of function calls. Please note that -we here use `MB_LEN_MAX' as the size argument in the `mbrlen' call. -This is acceptable since a) this value is larger then the length of the -longest multibyte character sequence and b) we know that the string S -ends with a NUL byte, which cannot be part of any other multibyte -character sequence but the one representing the NUL wide character. -Therefore, the `mbrlen' function will never read invalid memory. - - Now that this function is available (just to make this clear, this -function is _not_ part of the GNU C library) we can compute the number -of wide character required to store the converted multibyte character -string S using - - wcs_bytes = (mbslen (s) + 1) * sizeof (wchar_t); - - Please note that the `mbslen' function is quite inefficient. The -implementation of `mbstouwcs' with `mbslen' would have to perform the -conversion of the multibyte character input string twice, and this -conversion might be quite expensive. So it is necessary to think about -the consequences of using the easier but imprecise method before doing -the work twice. - - - Function: size_t wcrtomb (char *restrict S, wchar_t WC, mbstate_t - *restrict PS) - The `wcrtomb' function ("wide character restartable to multibyte") - converts a single wide character into a multibyte string - corresponding to that wide character. - - If S is a null pointer, the function resets the state stored in - the objects pointed to by PS (or the internal `mbstate_t' object) - to the initial state. This can also be achieved by a call like - this: - - wcrtombs (temp_buf, L'\0', ps) - - since, if S is a null pointer, `wcrtomb' performs as if it writes - into an internal buffer, which is guaranteed to be large enough. - - If WC is the NUL wide character, `wcrtomb' emits, if necessary, a - shift sequence to get the state PS into the initial state followed - by a single NUL byte, which is stored in the string S. - - Otherwise a byte sequence (possibly including shift sequences) is - written into the string S. This only happens if WC is a valid wide - character (i.e., it has a multibyte representation in the - character set selected by locale of the `LC_CTYPE' category). If - WC is no valid wide character, nothing is stored in the strings S, - `errno' is set to `EILSEQ', the conversion state in PS is - undefined and the return value is `(size_t) -1'. - - If no error occurred the function returns the number of bytes - stored in the string S. This includes all bytes representing shift - sequences. - - One word about the interface of the function: there is no parameter - specifying the length of the array S. Instead the function - assumes that there are at least `MB_CUR_MAX' bytes available since - this is the maximum length of any byte sequence representing a - single character. So the caller has to make sure that there is - enough space available, otherwise buffer overruns can occur. - - `wcrtomb' was introduced in Amendment 1 to ISO C90 and is declared - in `wchar.h'. - - Using `wcrtomb' is as easy as using `mbrtowc'. The following -example appends a wide character string to a multibyte character string. -Again, the code is not really useful (or correct), it is simply here to -demonstrate the use and some problems. - - char * - mbscatwcs (char *s, size_t len, const wchar_t *ws) - { - mbstate_t state; - /* Find the end of the existing string. */ - char *wp = strchr (s, '\0'); - len -= wp - s; - memset (&state, '\0', sizeof (state)); - do - { - size_t nbytes; - if (len < MB_CUR_LEN) - { - /* We cannot guarantee that the next - character fits into the buffer, so - return an error. */ - errno = E2BIG; - return NULL; - } - nbytes = wcrtomb (wp, *ws, &state); - if (nbytes == (size_t) -1) - /* Error in the conversion. */ - return NULL; - len -= nbytes; - wp += nbytes; - } - while (*ws++ != L'\0'); - return s; - } - - First the function has to find the end of the string currently in the -array S. The `strchr' call does this very efficiently since a -requirement for multibyte character representations is that the NUL byte -is never used except to represent itself (and in this context, the end -of the string). - - After initializing the state object the loop is entered where the -first task is to make sure there is enough room in the array S. We -abort if there are not at least `MB_CUR_LEN' bytes available. This is -not always optimal but we have no other choice. We might have less -than `MB_CUR_LEN' bytes available but the next multibyte character -might also be only one byte long. At the time the `wcrtomb' call -returns it is too late to decide whether the buffer was large enough. -If this solution is unsuitable, there is a very slow but more accurate -solution. - - ... - if (len < MB_CUR_LEN) - { - mbstate_t temp_state; - memcpy (&temp_state, &state, sizeof (state)); - if (wcrtomb (NULL, *ws, &temp_state) > len) - { - /* We cannot guarantee that the next - character fits into the buffer, so - return an error. */ - errno = E2BIG; - return NULL; - } - } - ... - - Here we perform the conversion that might overflow the buffer so that -we are afterwards in the position to make an exact decision about the -buffer size. Please note the `NULL' argument for the destination -buffer in the new `wcrtomb' call; since we are not interested in the -converted text at this point, this is a nice way to express this. The -most unusual thing about this piece of code certainly is the duplication -of the conversion state object, but if a change of the state is -necessary to emit the next multibyte character, we want to have the -same shift state change performed in the real conversion. Therefore, -we have to preserve the initial shift state information. - - There are certainly many more and even better solutions to this -problem. This example is only provided for educational purposes. - - -File: libc.info, Node: Converting Strings, Next: Multibyte Conversion Example, Prev: Converting a Character, Up: Restartable multibyte conversion - -Converting Multibyte and Wide Character Strings ------------------------------------------------ - - The functions described in the previous section only convert a single -character at a time. Most operations to be performed in real-world -programs include strings and therefore the ISO C standard also defines -conversions on entire strings. However, the defined set of functions -is quite limited; therefore, the GNU C library contains a few -extensions that can help in some important situations. - - - Function: size_t mbsrtowcs (wchar_t *restrict DST, const char - **restrict SRC, size_t LEN, mbstate_t *restrict PS) - The `mbsrtowcs' function ("multibyte string restartable to wide - character string") converts an NUL-terminated multibyte character - string at `*SRC' into an equivalent wide character string, - including the NUL wide character at the end. The conversion is - started using the state information from the object pointed to by - PS or from an internal object of `mbsrtowcs' if PS is a null - pointer. Before returning, the state object is updated to match - the state after the last converted character. The state is the - initial state if the terminating NUL byte is reached and converted. - - If DST is not a null pointer, the result is stored in the array - pointed to by DST; otherwise, the conversion result is not - available since it is stored in an internal buffer. - - If LEN wide characters are stored in the array DST before reaching - the end of the input string, the conversion stops and LEN is - returned. If DST is a null pointer, LEN is never checked. - - Another reason for a premature return from the function call is if - the input string contains an invalid multibyte sequence. In this - case the global variable `errno' is set to `EILSEQ' and the - function returns `(size_t) -1'. - - In all other cases the function returns the number of wide - characters converted during this call. If DST is not null, - `mbsrtowcs' stores in the pointer pointed to by SRC either a null - pointer (if the NUL byte in the input string was reached) or the - address of the byte following the last converted multibyte - character. - - `mbsrtowcs' was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. - - The definition of the `mbsrtowcs' function has one important -limitation. The requirement that DST has to be a NUL-terminated string -provides problems if one wants to convert buffers with text. A buffer -is normally no collection of NUL-terminated strings but instead a -continuous collection of lines, separated by newline characters. Now -assume that a function to convert one line from a buffer is needed. -Since the line is not NUL-terminated, the source pointer cannot -directly point into the unmodified text buffer. This means, either one -inserts the NUL byte at the appropriate place for the time of the -`mbsrtowcs' function call (which is not doable for a read-only buffer -or in a multi-threaded application) or one copies the line in an extra -buffer where it can be terminated by a NUL byte. Note that it is not -in general possible to limit the number of characters to convert by -setting the parameter LEN to any specific value. Since it is not known -how many bytes each multibyte character sequence is in length, one can -only guess. - - There is still a problem with the method of NUL-terminating a line -right after the newline character, which could lead to very strange -results. As said in the description of the `mbsrtowcs' function above -the conversion state is guaranteed to be in the initial shift state -after processing the NUL byte at the end of the input string. But this -NUL byte is not really part of the text (i.e., the conversion state -after the newline in the original text could be something different -than the initial shift state and therefore the first character of the -next line is encoded using this state). But the state in question is -never accessible to the user since the conversion stops after the NUL -byte (which resets the state). Most stateful character sets in use -today require that the shift state after a newline be the initial -state-but this is not a strict guarantee. Therefore, simply -NUL-terminating a piece of a running text is not always an adequate -solution and, therefore, should never be used in generally used code. - - The generic conversion interface (*note Generic Charset Conversion::) -does not have this limitation (it simply works on buffers, not -strings), and the GNU C library contains a set of functions that take -additional parameters specifying the maximal number of bytes that are -consumed from the input string. This way the problem of `mbsrtowcs''s -example above could be solved by determining the line length and -passing this length to the function. - - - Function: size_t wcsrtombs (char *restrict DST, const wchar_t - **restrict SRC, size_t LEN, mbstate_t *restrict PS) - The `wcsrtombs' function ("wide character string restartable to - multibyte string") converts the NUL-terminated wide character - string at `*SRC' into an equivalent multibyte character string and - stores the result in the array pointed to by DST. The NUL wide - character is also converted. The conversion starts in the state - described in the object pointed to by PS or by a state object - locally to `wcsrtombs' in case PS is a null pointer. If DST is a - null pointer, the conversion is performed as usual but the result - is not available. If all characters of the input string were - successfully converted and if DST is not a null pointer, the - pointer pointed to by SRC gets assigned a null pointer. - - If one of the wide characters in the input string has no valid - multibyte character equivalent, the conversion stops early, sets - the global variable `errno' to `EILSEQ', and returns `(size_t) -1'. - - Another reason for a premature stop is if DST is not a null - pointer and the next converted character would require more than - LEN bytes in total to the array DST. In this case (and if DEST is - not a null pointer) the pointer pointed to by SRC is assigned a - value pointing to the wide character right after the last one - successfully converted. - - Except in the case of an encoding error the return value of the - `wcsrtombs' function is the number of bytes in all the multibyte - character sequences stored in DST. Before returning the state in - the object pointed to by PS (or the internal object in case PS is - a null pointer) is updated to reflect the state after the last - conversion. The state is the initial shift state in case the - terminating NUL wide character was converted. - - The `wcsrtombs' function was introduced in Amendment 1 to ISO C90 - and is declared in `wchar.h'. - - The restriction mentioned above for the `mbsrtowcs' function applies -here also. There is no possibility of directly controlling the number -of input characters. One has to place the NUL wide character at the -correct place or control the consumed input indirectly via the -available output array size (the LEN parameter). - - - Function: size_t mbsnrtowcs (wchar_t *restrict DST, const char - **restrict SRC, size_t NMC, size_t LEN, mbstate_t *restrict - PS) - The `mbsnrtowcs' function is very similar to the `mbsrtowcs' - function. All the parameters are the same except for NMC, which is - new. The return value is the same as for `mbsrtowcs'. - - This new parameter specifies how many bytes at most can be used - from the multibyte character string. In other words, the - multibyte character string `*SRC' need not be NUL-terminated. But - if a NUL byte is found within the NMC first bytes of the string, - the conversion stops here. - - This function is a GNU extension. It is meant to work around the - problems mentioned above. Now it is possible to convert a buffer - with multibyte character text piece for piece without having to - care about inserting NUL bytes and the effect of NUL bytes on the - conversion state. - - A function to convert a multibyte string into a wide character string -and display it could be written like this (this is not a really useful -example): - - void - showmbs (const char *src, FILE *fp) - { - mbstate_t state; - int cnt = 0; - memset (&state, '\0', sizeof (state)); - while (1) - { - wchar_t linebuf[100]; - const char *endp = strchr (src, '\n'); - size_t n; - - /* Exit if there is no more line. */ - if (endp == NULL) - break; - - n = mbsnrtowcs (linebuf, &src, endp - src, 99, &state); - linebuf[n] = L'\0'; - fprintf (fp, "line %d: \"%S\"\n", linebuf); - } - } - - There is no problem with the state after a call to `mbsnrtowcs'. -Since we don't insert characters in the strings that were not in there -right from the beginning and we use STATE only for the conversion of -the given buffer, there is no problem with altering the state. - - - Function: size_t wcsnrtombs (char *restrict DST, const wchar_t - **restrict SRC, size_t NWC, size_t LEN, mbstate_t *restrict - PS) - The `wcsnrtombs' function implements the conversion from wide - character strings to multibyte character strings. It is similar to - `wcsrtombs' but, just like `mbsnrtowcs', it takes an extra - parameter, which specifies the length of the input string. - - No more than NWC wide characters from the input string `*SRC' are - converted. If the input string contains a NUL wide character in - the first NWC characters, the conversion stops at this place. - - The `wcsnrtombs' function is a GNU extension and just like - `mbsnrtowcs' helps in situations where no NUL-terminated input - strings are available. - diff -u -udbrN glibc-2.3.2/manual/libc.pg glibc-2.3.2-200304020432/manual/libc.pg --- glibc-2.3.2/manual/libc.pg Tue Feb 25
