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()>.

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.

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.
