+-=head1 NAME
+-
+-POSIX - Perl interface to IEEE Std 1003.1
+-
+-=head1 SYNOPSIS
+-
+- use POSIX;
+- use POSIX qw(setsid);
+- use POSIX qw(:errno_h :fcntl_h);
+-
+- printf "EINTR is %d\n", EINTR;
+-
+- $sess_id = POSIX::setsid();
+-
+- $fd = POSIX::open($path, O_CREAT|O_EXCL|O_WRONLY, 0644);
+- # note: that's a filedescriptor, *NOT* a filehandle
+-
+-=head1 DESCRIPTION
+-
+-The POSIX module permits you to access all (or nearly all) the standard
+-POSIX 1003.1 identifiers. Many of these identifiers have been given Perl-ish
+-interfaces.
+-
+-I<Everything is exported by default> with the exception of any POSIX
+-functions with the same name as a built-in Perl function, such as
+-C<abs>, C<alarm>, C<rmdir>, C<write>, etc.., which will be exported
+-only if you ask for them explicitly. This is an unfortunate backwards
+-compatibility feature. You can stop the exporting by saying C<use
+-POSIX ()> and then use the fully qualified names (ie. C<POSIX::SEEK_END>).
+-
+-This document gives a condensed list of the features available in the POSIX
+-module. Consult your operating system's manpages for general information on
+-most features. Consult L<perlfunc> for functions which are noted as being
+-identical to Perl's builtin functions.
+-
+-The first section describes POSIX functions from the 1003.1 specification.
+-The second section describes some classes for signal objects, TTY objects,
+-and other miscellaneous objects. The remaining sections list various
+-constants and macros in an organization which roughly follows IEEE Std
+-1003.1b-1993.
+-
+-=head1 NOTE
+-
+-The POSIX module is probably the most complex Perl module supplied with
+-the standard distribution. It incorporates autoloading, namespace games,
+-and dynamic loading of code that's in Perl, C, or both. It's a great
+-source of wisdom.
+-
+-=head1 CAVEATS
+-
+-A few functions are not implemented because they are C specific. If you
+-attempt to call these, they will print a message telling you that they
+-aren't implemented, and suggest using the Perl equivalent should one
+-exist. For example, trying to access the setjmp() call will elicit the
+-message "setjmp() is C-specific: use eval {} instead".
+-
+-Furthermore, some evil vendors will claim 1003.1 compliance, but in fact
+-are not so: they will not pass the PCTS (POSIX Compliance Test Suites).
+-For example, one vendor may not define EDEADLK, or the semantics of the
+-errno values set by open(2) might not be quite right. Perl does not
+-attempt to verify POSIX compliance. That means you can currently
+-successfully say "use POSIX", and then later in your program you find
+-that your vendor has been lax and there's no usable ICANON macro after
+-all. This could be construed to be a bug.
+-
+-=head1 FUNCTIONS
+-
+-=over 8
+-
+-=item _exit
+-
+-This is identical to the C function C<_exit()>. It exits the program
+-immediately which means among other things buffered I/O is B<not> flushed.
+-
+-Note that when using threads and in Linux this is B<not> a good way to
+-exit a thread because in Linux processes and threads are kind of the
+-same thing (Note: while this is the situation in early 2003 there are
+-projects under way to have threads with more POSIXly semantics in Linux).
+-If you want not to return from a thread, detach the thread.
+-
+-=item abort
+-
+-This is identical to the C function C<abort()>. It terminates the
+-process with a C<SIGABRT> signal unless caught by a signal handler or
+-if the handler does not return normally (it e.g. does a C<longjmp>).
+-
+-=item abs
+-
+-This is identical to Perl's builtin C<abs()> function, returning
+-the absolute value of its numerical argument.
+-
+-=item access
+-
+-Determines the accessibility of a file.
+-
+- if( POSIX::access( "/", &POSIX::R_OK ) ){
+- print "have read permission\n";
+- }
+-
+-Returns C<undef> on failure. Note: do not use C<access()> for
+-security purposes. Between the C<access()> call and the operation
+-you are preparing for the permissions might change: a classic
+-I<race condition>.
+-
+-=item acos
+-
+-This is identical to the C function C<acos()>, returning
+-the arcus cosine of its numerical argument. See also L<Math::Trig>.
+-
+-=item alarm
+-
+-This is identical to Perl's builtin C<alarm()> function,
+-either for arming or disarming the C<SIGARLM> timer.
+-
+-=item asctime
+-
+-This is identical to the C function C<asctime()>. It returns
+-a string of the form
+-
+- "Fri Jun 2 18:22:13 2000\n\0"
+-
+-and it is called thusly
+-
+- $asctime = asctime($sec, $min, $hour, $mday, $mon, $year,
+- $wday, $yday, $isdst);
+-
+-The C<$mon> is zero-based: January equals C<0>. The C<$year> is
+-1900-based: 2001 equals C<101>. C<$wday> and C<$yday> default to zero
+-(and are usually ignored anyway), and C<$isdst> defaults to -1.
+-
+-=item asin
+-
+-This is identical to the C function C<asin()>, returning
+-the arcus sine of its numerical argument. See also L<Math::Trig>.
+-
+-=item assert
+-
+-Unimplemented, but you can use L<perlfunc/die> and the L<Carp> module
+-to achieve similar things.
+-
+-=item atan
+-
+-This is identical to the C function C<atan()>, returning the
+-arcus tangent of its numerical argument. See also L<Math::Trig>.
+-
+-=item atan2
+-
+-This is identical to Perl's builtin C<atan2()> function, returning
+-the arcus tangent defined by its two numerical arguments, the I<y>
+-coordinate and the I<x> coordinate. See also L<Math::Trig>.
+-
+-=item atexit
+-
+-atexit() is C-specific: use C<END {}> instead, see L<perlsub>.
+-
+-=item atof
+-
+-atof() is C-specific. Perl converts strings to numbers transparently.
+-If you need to force a scalar to a number, add a zero to it.
+-
+-=item atoi
+-
+-atoi() is C-specific. Perl converts strings to numbers transparently.
+-If you need to force a scalar to a number, add a zero to it.
+-If you need to have just the integer part, see L<perlfunc/int>.
+-
+-=item atol
+-
+-atol() is C-specific. Perl converts strings to numbers transparently.
+-If you need to force a scalar to a number, add a zero to it.
+-If you need to have just the integer part, see L<perlfunc/int>.
+-
+-=item bsearch
+-
+-bsearch() not supplied. For doing binary search on wordlists,
+-see L<Search::Dict>.
+-
+-=item calloc
+-
+-calloc() is C-specific. Perl does memory management transparently.
+-
+-=item ceil
+-
+-This is identical to the C function C<ceil()>, returning the smallest
+-integer value greater than or equal to the given numerical argument.
+-
+-=item chdir
+-
+-This is identical to Perl's builtin C<chdir()> function, allowing
+-one to change the working (default) directory, see L<perlfunc/chdir>.
+-
+-=item chmod
+-
+-This is identical to Perl's builtin C<chmod()> function, allowing
+-one to change file and directory permissions, see L<perlfunc/chmod>.
+-
+-=item chown
+-
+-This is identical to Perl's builtin C<chown()> function, allowing one
+-to change file and directory owners and groups, see L<perlfunc/chown>.
+-
+-=item clearerr
+-
+-Use the method C<IO::Handle::clearerr()> instead, to reset the error
+-state (if any) and EOF state (if any) of the given stream.
+-
+-=item clock
+-
+-This is identical to the C function C<clock()>, returning the
+-amount of spent processor time in microseconds.
+-
+-=item close
+-
+-Close the file. This uses file descriptors such as those obtained by calling
+-C<POSIX::open>.
+-
+- $fd = POSIX::open( "foo", &POSIX::O_RDONLY );
+- POSIX::close( $fd );
+-
+-Returns C<undef> on failure.
+-
+-See also L<perlfunc/close>.
+-
+-=item closedir
+-
+-This is identical to Perl's builtin C<closedir()> function for closing
+-a directory handle, see L<perlfunc/closedir>.
+-
+-=item cos
+-
+-This is identical to Perl's builtin C<cos()> function, for returning
+-the cosine of its numerical argument, see L<perlfunc/cos>.
+-See also L<Math::Trig>.
+-
+-=item cosh
+-
+-This is identical to the C function C<cosh()>, for returning
+-the hyperbolic cosine of its numeric argument. See also L<Math::Trig>.
+-
+-=item creat
+-
+-Create a new file. This returns a file descriptor like the ones returned by
+-C<POSIX::open>. Use C<POSIX::close> to close the file.
+-
+- $fd = POSIX::creat( "foo", 0611 );
+- POSIX::close( $fd );
+-
+-See also L<perlfunc/sysopen> and its C<O_CREAT> flag.
+-
+-=item ctermid
+-
+-Generates the path name for the controlling terminal.
+-
+- $path = POSIX::ctermid();
+-
+-=item ctime
+-
+-This is identical to the C function C<ctime()> and equivalent
+-to C<asctime(localtime(...))>, see L</asctime> and L</localtime>.
+-
+-=item cuserid
+-
+-Get the login name of the owner of the current process.
+-
+- $name = POSIX::cuserid();
+-
+-=item difftime
+-
+-This is identical to the C function C<difftime()>, for returning
+-the time difference (in seconds) between two times (as returned
+-by C<time()>), see L</time>.
+-
+-=item div
+-
+-div() is C-specific, use L<perlfunc/int> on the usual C</> division and
+-the modulus C<%>.
+-
+-=item dup
+-
+-This is similar to the C function C<dup()>, for duplicating a file
+-descriptor.
+-
+-This uses file descriptors such as those obtained by calling
+-C<POSIX::open>.
+-
+-Returns C<undef> on failure.
+-
+-=item dup2
+-
+-This is similar to the C function C<dup2()>, for duplicating a file
+-descriptor to an another known file descriptor.
+-
+-This uses file descriptors such as those obtained by calling
+-C<POSIX::open>.
+-
+-Returns C<undef> on failure.
+-
+-=item errno
+-
+-Returns the value of errno.
+-
+- $errno = POSIX::errno();
+-
+-This identical to the numerical values of the C<$!>, see L<perlvar/$ERRNO>.

+-
+-=item setpgid
+-
+-This is similar to the C function C<setpgid()> for
+-setting the process group identifier of the current process.
+-
+-Returns C<undef> on failure.
+-
+-=item setsid
+-
+-This is identical to the C function C<setsid()> for
+-setting the session identifier of the current process.
+-
+-=item setuid
+-
+-Sets the real user identifier and the effective user identifier for
+-this process. Similar to assigning a value to the Perl's builtin
+-C<$E<lt>> variable, see L<perlvar/$UID>, except that the latter
+-will change only the real user identifier.
+-
+-=item sigaction
+-
+-Detailed signal management. This uses C<POSIX::SigAction> objects for
+-the C<action> and C<oldaction> arguments (the oldaction can also be
+-just a hash reference). Consult your system's C<sigaction> manpage
+-for details, see also C<POSIX::SigRt>.
+-
+-Synopsis:
+-
+- sigaction(signal, action, oldaction = 0)
+-
+-Returns C<undef> on failure. The C<signal> must be a number (like
+-SIGHUP), not a string (like "SIGHUP"), though Perl does try hard
+-to understand you.
+-
+-If you use the SA_SIGINFO flag, the signal handler will in addition to
+-the first argument, the signal name, also receive a second argument, a
+-hash reference, inside which are the following keys with the following
+-semantics, as defined by POSIX/SUSv3:
+-
+- signo the signal number
+- errno the error number
+- code if this is zero or less, the signal was sent by
+- a user process and the uid and pid make sense,
+- otherwise the signal was sent by the kernel
+-
+-The following are also defined by POSIX/SUSv3, but unfortunately
+-not very widely implemented:
+-
+- pid the process id generating the signal
+- uid the uid of the process id generating the signal
+- status exit value or signal for SIGCHLD
+- band band event for SIGPOLL
+-
+-A third argument is also passed to the handler, which contains a copy
+-of the raw binary contents of the siginfo structure: if a system has
+-some non-POSIX fields, this third argument is where to unpack() them
+-from.
+-
+-Note that not all siginfo values make sense simultaneously (some are
+-valid only for certain signals, for example), and not all values make
+-sense from Perl perspective, you should to consult your system's
+-C<sigaction> and possibly also C<siginfo> documentation.
+-
+-=item siglongjmp
+-
+-siglongjmp() is C-specific: use L<perlfunc/die> instead.
+-
+-=item sigpending
+-
+-Examine signals that are blocked and pending. This uses C<POSIX::SigSet>
+-objects for the C<sigset> argument. Consult your system's C<sigpending>
+-manpage for details.
+-
+-Synopsis:
+-
+- sigpending(sigset)
+-
+-Returns C<undef> on failure.
+-
+-=item sigprocmask
+-
+-Change and/or examine calling process's signal mask. This uses
+-C<POSIX::SigSet> objects for the C<sigset> and C<oldsigset> arguments.
+-Consult your system's C<sigprocmask> manpage for details.
+-
+-Synopsis:
+-
+- sigprocmask(how, sigset, oldsigset = 0)
+-
+-Returns C<undef> on failure.
+-
+-=item sigsetjmp
+-
+-C<sigsetjmp()> is C-specific: use C<eval {}> instead,
+-see L<perlfunc/eval>.
+-
+-=item sigsuspend
+-
+-Install a signal mask and suspend process until signal arrives. This uses
+-C<POSIX::SigSet> objects for the C<signal_mask> argument. Consult your
+-system's C<sigsuspend> manpage for details.
+-
+-Synopsis:
+-
+- sigsuspend(signal_mask)
+-
+-Returns C<undef> on failure.
+-
+-=item sin
+-
+-This is identical to Perl's builtin C<sin()> function
+-for returning the sine of the numerical argument,
+-see L<perlfunc/sin>. See also L<Math::Trig>.
+-
+-=item sinh
+-
+-This is identical to the C function C<sinh()>
+-for returning the hyperbolic sine of the numerical argument.
+-See also L<Math::Trig>.
+-
+-=item sleep
+-
+-This is functionally identical to Perl's builtin C<sleep()> function
+-for suspending the execution of the current for process for certain
+-number of seconds, see L<perlfunc/sleep>. There is one significant
+-difference, however: C<POSIX::sleep()> returns the number of
+-B<unslept> seconds, while the C<CORE::sleep()> returns the
+-number of slept seconds.
+-
+-=item sprintf
+-
+-This is similar to Perl's builtin C<sprintf()> function
+-for returning a string that has the arguments formatted as requested,
+-see L<perlfunc/sprintf>.
+-
+-=item sqrt
+-
+-This is identical to Perl's builtin C<sqrt()> function.
+-for returning the square root of the numerical argument,
+-see L<perlfunc/sqrt>.
+-
+-=item srand
+-
+-Give a seed the pseudorandom number generator, see L<perlfunc/srand>.
+-
+-=item sscanf
+-
+-sscanf() is C-specific, use regular expressions instead,
+-see L<perlre>.
+-
+-=item stat
+-
+-This is identical to Perl's builtin C<stat()> function
+-for returning information about files and directories.
+-
+-=item strcat
+-
+-strcat() is C-specific, use C<.=> instead, see L<perlop>.
+-
+-=item strchr
+-
+-strchr() is C-specific, see L<perlfunc/index> instead.
+-
+-=item strcmp
+-
+-strcmp() is C-specific, use C<eq> or C<cmp> instead, see L<perlop>.
+-
+-=item strcoll
+-
+-This is identical to the C function C<strcoll()>
+-for collating (comparing) strings transformed using
+-the C<strxfrm()> function. Not really needed since
+-Perl can do this transparently, see L<perllocale>.
+-
+-=item strcpy
+-
+-strcpy() is C-specific, use C<=> instead, see L<perlop>.
+-
+-=item strcspn
+-
+-strcspn() is C-specific, use regular expressions instead,
+-see L<perlre>.
+-
+-=item strerror
+-
+-Returns the error string for the specified errno.
+-Identical to the string form of the C<$!>, see L<perlvar/$ERRNO>.
+-
+-=item strftime
+-
+-Convert date and time information to string. Returns the string.
+-
+-Synopsis:
+-
+- strftime(fmt, sec, min, hour, mday, mon, year, wday = -1, yday = -1, isdst = -1)
+-
+-The month (C<mon>), weekday (C<wday>), and yearday (C<yday>) begin at zero.
+-I.e. January is 0, not 1; Sunday is 0, not 1; January 1st is 0, not 1. The
+-year (C<year>) is given in years since 1900. I.e., the year 1995 is 95; the
+-year 2001 is 101. Consult your system's C<strftime()> manpage for details
+-about these and the other arguments.
+-
+-If you want your code to be portable, your format (C<fmt>) argument
+-should use only the conversion specifiers defined by the ANSI C
+-standard (C89, to play safe). These are C<aAbBcdHIjmMpSUwWxXyYZ%>.
+-But even then, the B<results> of some of the conversion specifiers are
+-non-portable. For example, the specifiers C<aAbBcpZ> change according
+-to the locale settings of the user, and both how to set locales (the
+-locale names) and what output to expect are non-standard.
+-The specifier C<c> changes according to the timezone settings of the
+-user and the timezone computation rules of the operating system.
+-The C<Z> specifier is notoriously unportable since the names of
+-timezones are non-standard. Sticking to the numeric specifiers is the
+-safest route.
+-
+-The given arguments are made consistent as though by calling
+-C<mktime()> before calling your system's C<strftime()> function,
+-except that the C<isdst> value is not affected.
+-
+-The string for Tuesday, December 12, 1995.
+-
+- $str = POSIX::strftime( "%A, %B %d, %Y", 0, 0, 0, 12, 11, 95, 2 );
+- print "$str\n";
+-
+-=item strlen

+-strspn() is C-specific, use regular expressions instead,
+-see L<perlre>.
+-
+-=item strstr
+-
+-This is identical to Perl's builtin C<index()> function,
+-see L<perlfunc/index>.
+-
+-=item strtod
+-
+-String to double translation. Returns the parsed number and the number
+-of characters in the unparsed portion of the string. Truly
+-POSIX-compliant systems set $! ($ERRNO) to indicate a translation
+-error, so clear $! before calling strtod. However, non-POSIX systems
+-may not check for overflow, and therefore will never set $!.
+-
+-strtod should respect any POSIX I<setlocale()> settings.
+-
+-To parse a string $str as a floating point number use
+-
+- $! = 0;
+- ($num, $n_unparsed) = POSIX::strtod($str);
+-
+-The second returned item and $! can be used to check for valid input:
+-
+- if (($str eq '') || ($n_unparsed != 0) || $!) {
+- die "Non-numeric input $str" . ($! ? ": $!\n" : "\n");
+- }
+-
+-When called in a scalar context strtod returns the parsed number.
+-
+-=item strtok
+-
+-strtok() is C-specific, use regular expressions instead, see
+-L<perlre>, or L<perlfunc/split>.
+-
+-=item strtol
+-
+-String to (long) integer translation. Returns the parsed number and
+-the number of characters in the unparsed portion of the string. Truly
+-POSIX-compliant systems set $! ($ERRNO) to indicate a translation
+-error, so clear $! before calling strtol. However, non-POSIX systems
+-may not check for overflow, and therefore will never set $!.
+-
+-strtol should respect any POSIX I<setlocale()> settings.
+-
+-To parse a string $str as a number in some base $base use
+-
+- $! = 0;
+- ($num, $n_unparsed) = POSIX::strtol($str, $base);
+-
+-The base should be zero or between 2 and 36, inclusive. When the base
+-is zero or omitted strtol will use the string itself to determine the
+-base: a leading "0x" or "0X" means hexadecimal; a leading "0" means
+-octal; any other leading characters mean decimal. Thus, "1234" is
+-parsed as a decimal number, "01234" as an octal number, and "0x1234"
+-as a hexadecimal number.
+-
+-The second returned item and $! can be used to check for valid input:
+-
+- if (($str eq '') || ($n_unparsed != 0) || !$!) {
+- die "Non-numeric input $str" . $! ? ": $!\n" : "\n";
+- }
+-
+-When called in a scalar context strtol returns the parsed number.
+-
+-=item strtoul
+-
+-String to unsigned (long) integer translation. strtoul() is identical
+-to strtol() except that strtoul() only parses unsigned integers. See
+-L</strtol> for details.
+-
+-Note: Some vendors supply strtod() and strtol() but not strtoul().
+-Other vendors that do supply strtoul() parse "-1" as a valid value.
+-
+-=item strxfrm
+-
+-String transformation. Returns the transformed string.
+-
+- $dst = POSIX::strxfrm( $src );
+-
+-Used in conjunction with the C<strcoll()> function, see L</strcoll>.

+-
+-=item time

+-This is identical to Perl's builtin C<time()> function
+-for returning the number of seconds since the epoch
+-(whatever it is for the system), see L<perlfunc/time>.
+-
+-=item times
+-
+-The times() function returns elapsed realtime since some point in the past

+-and system times used by child processes. All times are returned in clock
+-ticks.
+-
+- ($realtime, $user, $system, $cuser, $csystem) = POSIX::times();
+-
+-Note: Perl's builtin C<times()> function returns four values, measured in

+-
+-For security reasons, which are probably detailed in your system's

+-should not be used; instead see L<File::Temp>.
+-
+-=item tolower
+-
+-This is identical to the C function, except that it can apply to a single

+-
+-=item wcstombs
+-
+-This is identical to the C function C<wcstombs()>.

+-
+-accessor function for the "safe signals" flag of a SigAction object; see

+-
+-=head2 POSIX::SigRt
+-
+-=over 8
+-
+-=item %SIGRT
+-
+-A hash of the POSIX realtime signal handlers. It is an extension of
+-the standard %SIG, the $POSIX::SIGRT{SIGRTMIN} is roughly equivalent
+-to $SIG{SIGRTMIN}, but the right POSIX moves (see below) are made with
+-the POSIX::SigSet and POSIX::sigaction instead of accessing the %SIG.
+-
+-You can set the %POSIX::SIGRT elements to set the POSIX realtime
+-signal handlers, use C<delete> and C<exists> on the elements, and use
+-C<scalar> on the C<%POSIX::SIGRT> to find out how many POSIX realtime
+-signals there are available (SIGRTMAX - SIGRTMIN + 1, the SIGRTMAX is
+-a valid POSIX realtime signal).
+-
+-Setting the %SIGRT elements is equivalent to calling this:
+-
+- sub new {
+- my ($rtsig, $handler, $flags) = @_;
+- my $sigset = POSIX::SigSet($rtsig);
+- my $sigact = POSIX::SigAction->new($handler, $sigset, $flags);
+- sigaction($rtsig, $sigact);
+- }
+-
+-The flags default to zero, if you want something different you can
+-either use C<local> on $POSIX::SigRt::SIGACTION_FLAGS, or you can
+-derive from POSIX::SigRt and define your own C<new()> (the tied hash
+-STORE method of the %SIGRT calls C<new($rtsig, $handler, $SIGACTION_FLAGS)>,
+-where the $rtsig ranges from zero to SIGRTMAX - SIGRTMIN + 1).
+-
+-Just as with any signal, you can use sigaction($rtsig, undef, $oa) to
+-retrieve the installed signal handler (or, rather, the signal action).

++=head1 NAME
++
++POSIX - Perl interface to IEEE Std 1003.1
++
++=head1 SYNOPSIS
++
++ use POSIX;
++ use POSIX qw(setsid);
++ use POSIX qw(:errno_h :fcntl_h);
++
++ printf "EINTR is %d\n", EINTR;
++
++ $sess_id = POSIX::setsid();
++
++ $fd = POSIX::open($path, O_CREAT|O_EXCL|O_WRONLY, 0644);
++ # note: that's a filedescriptor, *NOT* a filehandle
++
++=head1 DESCRIPTION
++
++The POSIX module permits you to access all (or nearly all) the standard
++POSIX 1003.1 identifiers. Many of these identifiers have been given Perl-ish
++interfaces.
++
++I<Everything is exported by default> with the exception of any POSIX
++functions with the same name as a built-in Perl function, such as
++C<abs>, C<alarm>, C<rmdir>, C<write>, etc.., which will be exported
++only if you ask for them explicitly. This is an unfortunate backwards
++compatibility feature. You can stop the exporting by saying C<use
++POSIX ()> and then use the fully qualified names (ie. C<POSIX::SEEK_END>).
++
++This document gives a condensed list of the features available in the POSIX
++module. Consult your operating system's manpages for general information on
++most features. Consult L<perlfunc> for functions which are noted as being
++identical to Perl's builtin functions.
++
++The first section describes POSIX functions from the 1003.1 specification.
++The second section describes some classes for signal objects, TTY objects,
++and other miscellaneous objects. The remaining sections list various
++constants and macros in an organization which roughly follows IEEE Std
++1003.1b-1993.
++
++=head1 NOTE
++
++The POSIX module is probably the most complex Perl module supplied with
++the standard distribution. It incorporates autoloading, namespace games,
++and dynamic loading of code that's in Perl, C, or both. It's a great
++source of wisdom.
++
++=head1 CAVEATS
++
++A few functions are not implemented because they are C specific. If you
++attempt to call these, they will print a message telling you that they
++aren't implemented, and suggest using the Perl equivalent should one
++exist. For example, trying to access the setjmp() call will elicit the
++message "setjmp() is C-specific: use eval {} instead".
++
++Furthermore, some evil vendors will claim 1003.1 compliance, but in fact
++are not so: they will not pass the PCTS (POSIX Compliance Test Suites).
++For example, one vendor may not define EDEADLK, or the semantics of the
++errno values set by open(2) might not be quite right. Perl does not
++attempt to verify POSIX compliance. That means you can currently
++successfully say "use POSIX", and then later in your program you find
++that your vendor has been lax and there's no usable ICANON macro after
++all. This could be construed to be a bug.
++
++=head1 FUNCTIONS
++
++=over 8
++
++=item _exit
++
++This is identical to the C function C<_exit()>. It exits the program
++immediately which means among other things buffered I/O is B<not> flushed.
++
++Note that when using threads and in Linux this is B<not> a good way to
++exit a thread because in Linux processes and threads are kind of the
++same thing (Note: while this is the situation in early 2003 there are
++projects under way to have threads with more POSIXly semantics in Linux).
++If you want not to return from a thread, detach the thread.
++
++=item abort
++
++This is identical to the C function C<abort()>. It terminates the
++process with a C<SIGABRT> signal unless caught by a signal handler or
++if the handler does not return normally (it e.g. does a C<longjmp>).
++
++=item abs
++
++This is identical to Perl's builtin C<abs()> function, returning
++the absolute value of its numerical argument.
++
++=item access
++
++Determines the accessibility of a file.
++
++ if( POSIX::access( "/", &POSIX::R_OK ) ){
++ print "have read permission\n";
++ }
++
++Returns C<undef> on failure. Note: do not use C<access()> for
++security purposes. Between the C<access()> call and the operation
++you are preparing for the permissions might change: a classic
++I<race condition>.
++
++=item acos
++
++This is identical to the C function C<acos()>, returning
++the arcus cosine of its numerical argument. See also L<Math::Trig>.
++
++=item alarm
++
++This is identical to Perl's builtin C<alarm()> function,
++either for arming or disarming the C<SIGARLM> timer.
++
++=item asctime
++
++This is identical to the C function C<asctime()>. It returns
++a string of the form
++
++ "Fri Jun 2 18:22:13 2000\n\0"
++
++and it is called thusly
++
++ $asctime = asctime($sec, $min, $hour, $mday, $mon, $year,
++ $wday, $yday, $isdst);
++
++The C<$mon> is zero-based: January equals C<0>. The C<$year> is
++1900-based: 2001 equals C<101>. C<$wday> and C<$yday> default to zero
++(and are usually ignored anyway), and C<$isdst> defaults to -1.
++
++=item asin
++
++This is identical to the C function C<asin()>, returning
++the arcus sine of its numerical argument. See also L<Math::Trig>.
++
++=item assert
++
++Unimplemented, but you can use L<perlfunc/die> and the L<Carp> module
++to achieve similar things.
++
++=item atan
++
++This is identical to the C function C<atan()>, returning the
++arcus tangent of its numerical argument. See also L<Math::Trig>.
++
++=item atan2
++
++This is identical to Perl's builtin C<atan2()> function, returning
++the arcus tangent defined by its two numerical arguments, the I<y>
++coordinate and the I<x> coordinate. See also L<Math::Trig>.
++
++=item atexit
++
++atexit() is C-specific: use C<END {}> instead, see L<perlsub>.
++
++=item atof
++
++atof() is C-specific. Perl converts strings to numbers transparently.
++If you need to force a scalar to a number, add a zero to it.
++
++=item atoi
++
++atoi() is C-specific. Perl converts strings to numbers transparently.
++If you need to force a scalar to a number, add a zero to it.
++If you need to have just the integer part, see L<perlfunc/int>.
++
++=item atol
++
++atol() is C-specific. Perl converts strings to numbers transparently.
++If you need to force a scalar to a number, add a zero to it.
++If you need to have just the integer part, see L<perlfunc/int>.
++
++=item bsearch
++
++bsearch() not supplied. For doing binary search on wordlists,
++see L<Search::Dict>.
++
++=item calloc
++
++calloc() is C-specific. Perl does memory management transparently.
++
++=item ceil
++
++This is identical to the C function C<ceil()>, returning the smallest
++integer value greater than or equal to the given numerical argument.
++
++=item chdir
++
++This is identical to Perl's builtin C<chdir()> function, allowing
++one to change the working (default) directory, see L<perlfunc/chdir>.
++
++=item chmod
++
++This is identical to Perl's builtin C<chmod()> function, allowing
++one to change file and directory permissions, see L<perlfunc/chmod>.
++
++=item chown
++
++This is identical to Perl's builtin C<chown()> function, allowing one
++to change file and directory owners and groups, see L<perlfunc/chown>.
++
++=item clearerr
++
++Use the method C<IO::Handle::clearerr()> instead, to reset the error
++state (if any) and EOF state (if any) of the given stream.
++
++=item clock
++
++This is identical to the C function C<clock()>, returning the
++amount of spent processor time in microseconds.
++
++=item close
++
++Close the file. This uses file descriptors such as those obtained by calling
++C<POSIX::open>.
++
++ $fd = POSIX::open( "foo", &POSIX::O_RDONLY );
++ POSIX::close( $fd );
++
++Returns C<undef> on failure.
++
++See also L<perlfunc/close>.
++
++=item closedir
++
++This is identical to Perl's builtin C<closedir()> function for closing
++a directory handle, see L<perlfunc/closedir>.
++
++=item cos
++
++This is identical to Perl's builtin C<cos()> function, for returning
++the cosine of its numerical argument, see L<perlfunc/cos>.
++See also L<Math::Trig>.
++
++=item cosh
++
++This is identical to the C function C<cosh()>, for returning
++the hyperbolic cosine of its numeric argument. See also L<Math::Trig>.
++
++=item creat
++
++Create a new file. This returns a file descriptor like the ones returned by
++C<POSIX::open>. Use C<POSIX::close> to close the file.
++
++ $fd = POSIX::creat( "foo", 0611 );
++ POSIX::close( $fd );
++
++See also L<perlfunc/sysopen> and its C<O_CREAT> flag.
++
++=item ctermid
++
++Generates the path name for the controlling terminal.
++
++ $path = POSIX::ctermid();
++
++=item ctime
++
++This is identical to the C function C<ctime()> and equivalent
++to C<asctime(localtime(...))>, see L</asctime> and L</localtime>.
++
++=item cuserid
++
++Get the login name of the owner of the current process.
++
++ $name = POSIX::cuserid();
++
++=item difftime
++
++This is identical to the C function C<difftime()>, for returning
++the time difference (in seconds) between two times (as returned
++by C<time()>), see L</time>.
++
++=item div
++
++div() is C-specific, use L<perlfunc/int> on the usual C</> division and
++the modulus C<%>.
++
++=item dup
++
++This is similar to the C function C<dup()>, for duplicating a file
++descriptor.
++
++This uses file descriptors such as those obtained by calling
++C<POSIX::open>.
++
++Returns C<undef> on failure.
++
++=item dup2
++
++This is similar to the C function C<dup2()>, for duplicating a file
++descriptor to an another known file descriptor.
++
++This uses file descriptors such as those obtained by calling
++C<POSIX::open>.
++
++Returns C<undef> on failure.
++
++=item errno
++
++Returns the value of errno.
++
++ $errno = POSIX::errno();

++execl() is C-specific, see L<perlfunc/exec>.
++
++=item execle
++
++execle() is C-specific, see L<perlfunc/exec>.

++
++=item setpgid
++
++This is similar to the C function C<setpgid()> for
++setting the process group identifier of the current process.
++
++Returns C<undef> on failure.
++
++=item setsid
++
++This is identical to the C function C<setsid()> for
++setting the session identifier of the current process.
++
++=item setuid
++
++Sets the real user identifier and the effective user identifier for
++this process. Similar to assigning a value to the Perl's builtin
++C<$E<lt>> variable, see L<perlvar/$UID>, except that the latter
++will change only the real user identifier.
++
++=item sigaction
++
++Detailed signal management. This uses C<POSIX::SigAction> objects for
++the C<action> and C<oldaction> arguments (the oldaction can also be
++just a hash reference). Consult your system's C<sigaction> manpage
++for details, see also C<POSIX::SigRt>.
++
++Synopsis:
++
++ sigaction(signal, action, oldaction = 0)
++
++Returns C<undef> on failure. The C<signal> must be a number (like
++SIGHUP), not a string (like "SIGHUP"), though Perl does try hard
++to understand you.
++
++If you use the SA_SIGINFO flag, the signal handler will in addition to
++the first argument, the signal name, also receive a second argument, a
++hash reference, inside which are the following keys with the following
++semantics, as defined by POSIX/SUSv3:
++
++ signo the signal number
++ errno the error number
++ code if this is zero or less, the signal was sent by
++ a user process and the uid and pid make sense,
++ otherwise the signal was sent by the kernel
++
++The following are also defined by POSIX/SUSv3, but unfortunately
++not very widely implemented:
++
++ pid the process id generating the signal
++ uid the uid of the process id generating the signal
++ status exit value or signal for SIGCHLD
++ band band event for SIGPOLL
++
++A third argument is also passed to the handler, which contains a copy
++of the raw binary contents of the siginfo structure: if a system has
++some non-POSIX fields, this third argument is where to unpack() them
++from.
++
++Note that not all siginfo values make sense simultaneously (some are
++valid only for certain signals, for example), and not all values make
++sense from Perl perspective, you should to consult your system's
++C<sigaction> and possibly also C<siginfo> documentation.
++
++=item siglongjmp
++
++siglongjmp() is C-specific: use L<perlfunc/die> instead.
++
++=item sigpending
++
++Examine signals that are blocked and pending. This uses C<POSIX::SigSet>
++objects for the C<sigset> argument. Consult your system's C<sigpending>
++manpage for details.
++
++Synopsis:
++
++ sigpending(sigset)
++
++Returns C<undef> on failure.
++
++=item sigprocmask
++
++Change and/or examine calling process's signal mask. This uses
++C<POSIX::SigSet> objects for the C<sigset> and C<oldsigset> arguments.
++Consult your system's C<sigprocmask> manpage for details.
++
++Synopsis:
++
++ sigprocmask(how, sigset, oldsigset = 0)
++
++Returns C<undef> on failure.
++
++=item sigsetjmp
++
++C<sigsetjmp()> is C-specific: use C<eval {}> instead,
++see L<perlfunc/eval>.
++
++=item sigsuspend
++
++Install a signal mask and suspend process until signal arrives. This uses
++C<POSIX::SigSet> objects for the C<signal_mask> argument. Consult your
++system's C<sigsuspend> manpage for details.
++
++Synopsis:
++
++ sigsuspend(signal_mask)
++
++Returns C<undef> on failure.
++
++=item sin
++
++This is identical to Perl's builtin C<sin()> function
++for returning the sine of the numerical argument,
++see L<perlfunc/sin>. See also L<Math::Trig>.
++
++=item sinh
++
++This is identical to the C function C<sinh()>
++for returning the hyperbolic sine of the numerical argument.
++See also L<Math::Trig>.
++
++=item sleep
++
++This is functionally identical to Perl's builtin C<sleep()> function
++for suspending the execution of the current for process for certain
++number of seconds, see L<perlfunc/sleep>. There is one significant
++difference, however: C<POSIX::sleep()> returns the number of
++B<unslept> seconds, while the C<CORE::sleep()> returns the
++number of slept seconds.
++
++=item sprintf
++
++This is similar to Perl's builtin C<sprintf()> function
++for returning a string that has the arguments formatted as requested,
++see L<perlfunc/sprintf>.
++
++=item sqrt
++
++This is identical to Perl's builtin C<sqrt()> function.
++for returning the square root of the numerical argument,
++see L<perlfunc/sqrt>.
++
++=item srand
++
++Give a seed the pseudorandom number generator, see L<perlfunc/srand>.
++
++=item sscanf
++
++sscanf() is C-specific, use regular expressions instead,
++see L<perlre>.
++
++=item stat
++
++This is identical to Perl's builtin C<stat()> function
++for returning information about files and directories.
++
++=item strcat
++
++strcat() is C-specific, use C<.=> instead, see L<perlop>.
++
++=item strchr
++
++strchr() is C-specific, see L<perlfunc/index> instead.
++
++=item strcmp
++
++strcmp() is C-specific, use C<eq> or C<cmp> instead, see L<perlop>.
++
++=item strcoll
++
++This is identical to the C function C<strcoll()>
++for collating (comparing) strings transformed using
++the C<strxfrm()> function. Not really needed since
++Perl can do this transparently, see L<perllocale>.
++
++=item strcpy
++
++strcpy() is C-specific, use C<=> instead, see L<perlop>.
++
++=item strcspn
++
++strcspn() is C-specific, use regular expressions instead,
++see L<perlre>.
++
++=item strerror
++
++Returns the error string for the specified errno.
++Identical to the string form of the C<$!>, see L<perlvar/$ERRNO>.
++
++=item strftime
++
++Convert date and time information to string. Returns the string.
++
++Synopsis:
++
++ strftime(fmt, sec, min, hour, mday, mon, year, wday = -1, yday = -1, isdst = -1)
++
++The month (C<mon>), weekday (C<wday>), and yearday (C<yday>) begin at zero.
++I.e. January is 0, not 1; Sunday is 0, not 1; January 1st is 0, not 1. The
++year (C<year>) is given in years since 1900. I.e., the year 1995 is 95; the
++year 2001 is 101. Consult your system's C<strftime()> manpage for details
++about these and the other arguments.
++
++If you want your code to be portable, your format (C<fmt>) argument
++should use only the conversion specifiers defined by the ANSI C
++standard (C89, to play safe). These are C<aAbBcdHIjmMpSUwWxXyYZ%>.
++But even then, the B<results> of some of the conversion specifiers are
++non-portable. For example, the specifiers C<aAbBcpZ> change according
++to the locale settings of the user, and both how to set locales (the
++locale names) and what output to expect are non-standard.
++The specifier C<c> changes according to the timezone settings of the
++user and the timezone computation rules of the operating system.
++The C<Z> specifier is notoriously unportable since the names of
++timezones are non-standard. Sticking to the numeric specifiers is the
++safest route.
++
++The given arguments are made consistent as though by calling
++C<mktime()> before calling your system's C<strftime()> function,
++except that the C<isdst> value is not affected.
++
++The string for Tuesday, December 12, 1995.
++
++ $str = POSIX::strftime( "%A, %B %d, %Y", 0, 0, 0, 12, 11, 95, 2 );
++ print "$str\n";
++
++=item strlen
++
++strlen() is C-specific, use C<length()> instead, see L<perlfunc/length>.
++
++=item strncat
++
++strncat() is C-specific, use C<.=> instead, see L<perlop>.
++
++=item strncmp
++
++strncmp() is C-specific, use C<eq> instead, see L<perlop>.

++
++strrchr() is C-specific, see L<perlfunc/rindex> instead.
++
++=item strspn
++
++strspn() is C-specific, use regular expressions instead,
++see L<perlre>.
++
++=item strstr
++
++This is identical to Perl's builtin C<index()> function,
++see L<perlfunc/index>.
++
++=item strtod
++
++String to double translation. Returns the parsed number and the number
++of characters in the unparsed portion of the string. Truly
++POSIX-compliant systems set $! ($ERRNO) to indicate a translation
++error, so clear $! before calling strtod. However, non-POSIX systems
++may not check for overflow, and therefore will never set $!.
++
++strtod should respect any POSIX I<setlocale()> settings.
++
++To parse a string $str as a floating point number use
++
++ $! = 0;
++ ($num, $n_unparsed) = POSIX::strtod($str);
++
++The second returned item and $! can be used to check for valid input:
++
++ if (($str eq '') || ($n_unparsed != 0) || $!) {
++ die "Non-numeric input $str" . ($! ? ": $!\n" : "\n");
++ }
++
++When called in a scalar context strtod returns the parsed number.
++
++=item strtok
++
++strtok() is C-specific, use regular expressions instead, see
++L<perlre>, or L<perlfunc/split>.
++
++=item strtol
++
++String to (long) integer translation. Returns the parsed number and
++the number of characters in the unparsed portion of the string. Truly
++POSIX-compliant systems set $! ($ERRNO) to indicate a translation
++error, so clear $! before calling strtol. However, non-POSIX systems
++may not check for overflow, and therefore will never set $!.
++
++strtol should respect any POSIX I<setlocale()> settings.
++
++To parse a string $str as a number in some base $base use
++
++ $! = 0;
++ ($num, $n_unparsed) = POSIX::strtol($str, $base);
++
++The base should be zero or between 2 and 36, inclusive. When the base
++is zero or omitted strtol will use the string itself to determine the
++base: a leading "0x" or "0X" means hexadecimal; a leading "0" means
++octal; any other leading characters mean decimal. Thus, "1234" is
++parsed as a decimal number, "01234" as an octal number, and "0x1234"
++as a hexadecimal number.
++
++The second returned item and $! can be used to check for valid input:
++
++ if (($str eq '') || ($n_unparsed != 0) || !$!) {
++ die "Non-numeric input $str" . $! ? ": $!\n" : "\n";
++ }
++
++When called in a scalar context strtol returns the parsed number.
++
++=item strtoul
++
++String to unsigned (long) integer translation. strtoul() is identical
++to strtol() except that strtoul() only parses unsigned integers. See
++L</strtol> for details.
++
++Note: Some vendors supply strtod() and strtol() but not strtoul().
++Other vendors that do supply strtoul() parse "-1" as a valid value.
++
++=item strxfrm
++
++String transformation. Returns the transformed string.
++
++ $dst = POSIX::strxfrm( $src );
++
++Used in conjunction with the C<strcoll()> function, see L</strcoll>.
++
++Not really needed since Perl can do this transparently, see
++L<perllocale>.
++
++=item sysconf
++
++Retrieves values of system configurable variables.

++
++=item tcsendbreak
++
++This is similar to the C function C<tcsendbreak()> for sending
++a break on its argument stream.
++
++Returns C<undef> on failure.
++
++=item tcsetpgrp
++
++This is similar to the C function C<tcsetpgrp()> for setting the
++process group identifier of the foreground process group of the controlling
++terminal.
++
++Returns C<undef> on failure.
++
++=item time
++
++This is identical to Perl's builtin C<time()> function
++for returning the number of seconds since the epoch
++(whatever it is for the system), see L<perlfunc/time>.
++
++=item times
++
++The times() function returns elapsed realtime since some point in the past
++(such as system startup), user and system times for this process, and user
++and system times used by child processes. All times are returned in clock
++ticks.
++
++ ($realtime, $user, $system, $cuser, $csystem) = POSIX::times();
++
++Note: Perl's builtin C<times()> function returns four values, measured in
++seconds.
++
++=item tmpfile
++
++Use method C<IO::File::new_tmpfile()> instead, or see L<File::Temp>.
++
++=item tmpnam
++
++Returns a name for a temporary file.
++
++ $tmpfile = POSIX::tmpnam();
++
++For security reasons, which are probably detailed in your system's
++documentation for the C library tmpnam() function, this interface
++should not be used; instead see L<File::Temp>.
++
++=item tolower
++
++This is identical to the C function, except that it can apply to a single
++character or to a whole string. Consider using the C<lc()> function,
++see L<perlfunc/lc>, or the equivalent C<\L> operator inside doublequotish
++strings.
++
++=item toupper
++
++This is identical to the C function, except that it can apply to a single
++character or to a whole string. Consider using the C<uc()> function,

++strings.
++
++=item ttyname
++
++This is identical to the C function C<ttyname()> for returning the
++name of the current terminal.
++
++=item tzname
++
++Retrieves the time conversion information from the C<tzname> variable.
++
++ POSIX::tzset();
++ ($std, $dst) = POSIX::tzname();
++
++=item tzset
++
++This is identical to the C function C<tzset()> for setting

++functions.
++
++=item umask

++This is identical to Perl's builtin C<umask()> function
++for setting (and querying) the file creation permission mask,
++see L<perlfunc/umask>.
++
++=item uname
++
++Get name of current operating system.
++
++ ($sysname, $nodename, $release, $version, $machine) = POSIX::uname();
++
++Note that the actual meanings of the various fields are not
++that well standardized, do not expect any great portability.
++The C<$sysname> might be the name of the operating system,

++
++=item wcstombs
++
++This is identical to the C function C<wcstombs()>.
++Perl does not have any support for the wide and multibyte
++characters of the C standards, so this might be a rather
++useless function.

++
++=item safe
++
++accessor function for the "safe signals" flag of a SigAction object; see

++
++=head2 POSIX::SigRt
++
++=over 8
++
++=item %SIGRT
++
++A hash of the POSIX realtime signal handlers. It is an extension of
++the standard %SIG, the $POSIX::SIGRT{SIGRTMIN} is roughly equivalent
++to $SIG{SIGRTMIN}, but the right POSIX moves (see below) are made with
++the POSIX::SigSet and POSIX::sigaction instead of accessing the %SIG.
++
++You can set the %POSIX::SIGRT elements to set the POSIX realtime
++signal handlers, use C<delete> and C<exists> on the elements, and use
++C<scalar> on the C<%POSIX::SIGRT> to find out how many POSIX realtime
++signals there are available (SIGRTMAX - SIGRTMIN + 1, the SIGRTMAX is
++a valid POSIX realtime signal).
++
++Setting the %SIGRT elements is equivalent to calling this:
++
++ sub new {
++ my ($rtsig, $handler, $flags) = @_;
++ my $sigset = POSIX::SigSet($rtsig);
++ my $sigact = POSIX::SigAction->new($handler, $sigset, $flags);
++ sigaction($rtsig, $sigact);
++ }
++
++The flags default to zero, if you want something different you can
++either use C<local> on $POSIX::SigRt::SIGACTION_FLAGS, or you can
++derive from POSIX::SigRt and define your own C<new()> (the tied hash
++STORE method of the %SIGRT calls C<new($rtsig, $handler, $SIGACTION_FLAGS)>,
++where the $rtsig ranges from zero to SIGRTMAX - SIGRTMIN + 1).
++
++Just as with any signal, you can use sigaction($rtsig, undef, $oa) to
