8 make_ext.pl populates @INC correctly, don't override it badly
9
10 PERL5LIB is populated by make_ext.pl with paths to the modules we need
11 to run, don't override this with "../../lib" since that may not have
12 been populated yet in a parallel build.

9
10 6695a346 changed the start of Makefile.PL, but t/posix.t reads that to
11 test its read() implementation, restore enough of the original for the

1094-=head1 NAME
1095-
1096-POSIX - Perl interface to IEEE Std 1003.1
1097-
1098-=head1 SYNOPSIS
1099-
1100- use POSIX;
1101- use POSIX qw(setsid);
1102- use POSIX qw(:errno_h :fcntl_h);
1103-
1104- printf "EINTR is %d\n", EINTR;
1105-
1106- $sess_id = POSIX::setsid();
1107-
1108- $fd = POSIX::open($path, O_CREAT|O_EXCL|O_WRONLY, 0644);
1109- # note: that's a filedescriptor, *NOT* a filehandle
1110-
1111-=head1 DESCRIPTION
1112-
1113-The POSIX module permits you to access all (or nearly all) the standard
1114-POSIX 1003.1 identifiers. Many of these identifiers have been given Perl-ish
1115-interfaces.
1116-
1117-I<Everything is exported by default> with the exception of any POSIX
1118-functions with the same name as a built-in Perl function, such as
1119-C<abs>, C<alarm>, C<rmdir>, C<write>, etc.., which will be exported
1120-only if you ask for them explicitly. This is an unfortunate backwards
1121-compatibility feature. You can stop the exporting by saying C<use
1122-POSIX ()> and then use the fully qualified names (ie. C<POSIX::SEEK_END>).
1123-
1124-This document gives a condensed list of the features available in the POSIX
1125-module. Consult your operating system's manpages for general information on
1126-most features. Consult L<perlfunc> for functions which are noted as being
1127-identical to Perl's builtin functions.
1128-
1129-The first section describes POSIX functions from the 1003.1 specification.
1130-The second section describes some classes for signal objects, TTY objects,
1131-and other miscellaneous objects. The remaining sections list various
1132-constants and macros in an organization which roughly follows IEEE Std
1133-1003.1b-1993.
1134-
1135-=head1 NOTE
1136-
1137-The POSIX module is probably the most complex Perl module supplied with
1138-the standard distribution. It incorporates autoloading, namespace games,
1139-and dynamic loading of code that's in Perl, C, or both. It's a great
1140-source of wisdom.
1141-
1142-=head1 CAVEATS
1143-
1144-A few functions are not implemented because they are C specific. If you
1145-attempt to call these, they will print a message telling you that they
1146-aren't implemented, and suggest using the Perl equivalent should one
1147-exist. For example, trying to access the setjmp() call will elicit the
1148-message "setjmp() is C-specific: use eval {} instead".
1149-
1150-Furthermore, some evil vendors will claim 1003.1 compliance, but in fact
1151-are not so: they will not pass the PCTS (POSIX Compliance Test Suites).
1152-For example, one vendor may not define EDEADLK, or the semantics of the
1153-errno values set by open(2) might not be quite right. Perl does not
1154-attempt to verify POSIX compliance. That means you can currently
1155-successfully say "use POSIX", and then later in your program you find
1156-that your vendor has been lax and there's no usable ICANON macro after
1157-all. This could be construed to be a bug.

1159-=head1 FUNCTIONS
1160-
1161-=over 8
1162-
1163-=item _exit
1164-
1165-This is identical to the C function C<_exit()>. It exits the program
1166-immediately which means among other things buffered I/O is B<not> flushed.
1167-
1168-Note that when using threads and in Linux this is B<not> a good way to
1169-exit a thread because in Linux processes and threads are kind of the
1170-same thing (Note: while this is the situation in early 2003 there are
1171-projects under way to have threads with more POSIXly semantics in Linux).
1172-If you want not to return from a thread, detach the thread.
1173-
1174-=item abort
1175-
1176-This is identical to the C function C<abort()>. It terminates the
1177-process with a C<SIGABRT> signal unless caught by a signal handler or
1178-if the handler does not return normally (it e.g. does a C<longjmp>).
1179-
1180-=item abs

1190- print "have read permission\n";
1191- }
1192-
1193-Returns C<undef> on failure. Note: do not use C<access()> for
1194-security purposes. Between the C<access()> call and the operation
1195-you are preparing for the permissions might change: a classic
1196-I<race condition>.
1197-
1198-=item acos
1199-
1200-This is identical to the C function C<acos()>, returning

1218- $wday, $yday, $isdst);
1219-

1221-1900-based: 2001 equals C<101>. C<$wday> and C<$yday> default to zero
1222-(and are usually ignored anyway), and C<$isdst> defaults to -1.
1223-
1224-=item asin
1225-
1226-This is identical to the C function C<asin()>, returning
1227-the arcus sine of its numerical argument. See also L<Math::Trig>.

2220-=item sigaction
2221-
2222-Detailed signal management. This uses C<POSIX::SigAction> objects for

2232-SIGHUP), not a string (like "SIGHUP"), though Perl does try hard
2233-to understand you.
2234-
2235-If you use the SA_SIGINFO flag, the signal handler will in addition to
2236-the first argument, the signal name, also receive a second argument, a
2237-hash reference, inside which are the following keys with the following
2238-semantics, as defined by POSIX/SUSv3:
2239-
2240- signo the signal number
2241- errno the error number
2242- code if this is zero or less, the signal was sent by
2243- a user process and the uid and pid make sense,
2244- otherwise the signal was sent by the kernel
2245-
2246-The following are also defined by POSIX/SUSv3, but unfortunately
2247-not very widely implemented:
2248-
2249- pid the process id generating the signal
2250- uid the uid of the process id generating the signal
2251- status exit value or signal for SIGCHLD
2252- band band event for SIGPOLL
2253-
2254-A third argument is also passed to the handler, which contains a copy
2255-of the raw binary contents of the siginfo structure: if a system has
2256-some non-POSIX fields, this third argument is where to unpack() them
2257-from.
2258-
2259-Note that not all siginfo values make sense simultaneously (some are
2260-valid only for certain signals, for example), and not all values make
2261-sense from Perl perspective, you should to consult your system's
2262-C<sigaction> and possibly also C<siginfo> documentation.

2398-I.e. January is 0, not 1; Sunday is 0, not 1; January 1st is 0, not 1. The
2399-year (C<year>) is given in years since 1900. I.e., the year 1995 is 95; the
2400-year 2001 is 101. Consult your system's C<strftime()> manpage for details
2401-about these and the other arguments.
2402-
2403-If you want your code to be portable, your format (C<fmt>) argument
2404-should use only the conversion specifiers defined by the ANSI C
2405-standard (C89, to play safe). These are C<aAbBcdHIjmMpSUwWxXyYZ%>.
2406-But even then, the B<results> of some of the conversion specifiers are
2407-non-portable. For example, the specifiers C<aAbBcpZ> change according
2408-to the locale settings of the user, and both how to set locales (the
2409-locale names) and what output to expect are non-standard.
2410-The specifier C<c> changes according to the timezone settings of the
2411-user and the timezone computation rules of the operating system.
2412-The C<Z> specifier is notoriously unportable since the names of
2413-timezones are non-standard. Sticking to the numeric specifiers is the
2414-safest route.
2415-
2416-The given arguments are made consistent as though by calling
2417-C<mktime()> before calling your system's C<strftime()> function,

2464-POSIX-compliant systems set $! ($ERRNO) to indicate a translation
2465-error, so clear $! before calling strtod. However, non-POSIX systems
2466-may not check for overflow, and therefore will never set $!.
2467-

2500- $! = 0;
2501- ($num, $n_unparsed) = POSIX::strtol($str, $base);
2502-
2503-The base should be zero or between 2 and 36, inclusive. When the base
2504-is zero or omitted strtol will use the string itself to determine the
2505-base: a leading "0x" or "0X" means hexadecimal; a leading "0" means
2506-octal; any other leading characters mean decimal. Thus, "1234" is
2507-parsed as a decimal number, "01234" as an octal number, and "0x1234"
2508-as a hexadecimal number.
2509-

2522-L</strtol> for details.
2523-
2524-Note: Some vendors supply strtod() and strtol() but not strtoul().
2525-Other vendors that do supply strtoul() parse "-1" as a valid value.

2797-
2798-accessor function for the "safe signals" flag of a SigAction object; see

2804-
2805-You may also examine the "safe" flag on the output action object which is

2816-

2818-
2819-=item %SIGRT
2820-
2821-A hash of the POSIX realtime signal handlers. It is an extension of
2822-the standard %SIG, the $POSIX::SIGRT{SIGRTMIN} is roughly equivalent
2823-to $SIG{SIGRTMIN}, but the right POSIX moves (see below) are made with
2824-the POSIX::SigSet and POSIX::sigaction instead of accessing the %SIG.
2825-
2826-You can set the %POSIX::SIGRT elements to set the POSIX realtime
2827-signal handlers, use C<delete> and C<exists> on the elements, and use
2828-C<scalar> on the C<%POSIX::SIGRT> to find out how many POSIX realtime
2829-signals there are available (SIGRTMAX - SIGRTMIN + 1, the SIGRTMAX is
2830-a valid POSIX realtime signal).
2831-
2832-Setting the %SIGRT elements is equivalent to calling this:
2833-
2834- sub new {
2835- my ($rtsig, $handler, $flags) = @_;
2836- my $sigset = POSIX::SigSet($rtsig);
2837- my $sigact = POSIX::SigAction->new($handler, $sigset, $flags);
2838- sigaction($rtsig, $sigact);
2839- }
2840-
2841-The flags default to zero, if you want something different you can
2842-either use C<local> on $POSIX::SigRt::SIGACTION_FLAGS, or you can
2843-derive from POSIX::SigRt and define your own C<new()> (the tied hash
2844-STORE method of the %SIGRT calls C<new($rtsig, $handler, $SIGACTION_FLAGS)>,
2845-where the $rtsig ranges from zero to SIGRTMAX - SIGRTMIN + 1).
2846-
2847-Just as with any signal, you can use sigaction($rtsig, undef, $oa) to
2848-retrieve the installed signal handler (or, rather, the signal action).
2849-
2850-B<NOTE:> whether POSIX realtime signals really work in your system, or

4366+=head1 NAME
4367+
4368+POSIX - Perl interface to IEEE Std 1003.1
4369+
4370+=head1 SYNOPSIS
4371+
4372+ use POSIX;
4373+ use POSIX qw(setsid);
4374+ use POSIX qw(:errno_h :fcntl_h);
4375+
4376+ printf "EINTR is %d\n", EINTR;
4377+
4378+ $sess_id = POSIX::setsid();
4379+
4380+ $fd = POSIX::open($path, O_CREAT|O_EXCL|O_WRONLY, 0644);
4381+ # note: that's a filedescriptor, *NOT* a filehandle
4382+
4383+=head1 DESCRIPTION
4384+
4385+The POSIX module permits you to access all (or nearly all) the standard
4386+POSIX 1003.1 identifiers. Many of these identifiers have been given Perl-ish
4387+interfaces.
4388+
4389+I<Everything is exported by default> with the exception of any POSIX
4390+functions with the same name as a built-in Perl function, such as
4391+C<abs>, C<alarm>, C<rmdir>, C<write>, etc.., which will be exported
4392+only if you ask for them explicitly. This is an unfortunate backwards
4393+compatibility feature. You can stop the exporting by saying C<use
4394+POSIX ()> and then use the fully qualified names (ie. C<POSIX::SEEK_END>).
4395+
4396+This document gives a condensed list of the features available in the POSIX
4397+module. Consult your operating system's manpages for general information on
4398+most features. Consult L<perlfunc> for functions which are noted as being
4399+identical to Perl's builtin functions.
4400+
4401+The first section describes POSIX functions from the 1003.1 specification.
4402+The second section describes some classes for signal objects, TTY objects,
4403+and other miscellaneous objects. The remaining sections list various
4404+constants and macros in an organization which roughly follows IEEE Std
4405+1003.1b-1993.
4406+
4407+=head1 NOTE
4408+
4409+The POSIX module is probably the most complex Perl module supplied with
4410+the standard distribution. It incorporates autoloading, namespace games,
4411+and dynamic loading of code that's in Perl, C, or both. It's a great
4412+source of wisdom.
4413+
4414+=head1 CAVEATS
4415+
4416+A few functions are not implemented because they are C specific. If you
4417+attempt to call these, they will print a message telling you that they
4418+aren't implemented, and suggest using the Perl equivalent should one
4419+exist. For example, trying to access the setjmp() call will elicit the
4420+message "setjmp() is C-specific: use eval {} instead".
4421+
4422+Furthermore, some evil vendors will claim 1003.1 compliance, but in fact
4423+are not so: they will not pass the PCTS (POSIX Compliance Test Suites).
4424+For example, one vendor may not define EDEADLK, or the semantics of the
4425+errno values set by open(2) might not be quite right. Perl does not
4426+attempt to verify POSIX compliance. That means you can currently
4427+successfully say "use POSIX", and then later in your program you find
4428+that your vendor has been lax and there's no usable ICANON macro after
4429+all. This could be construed to be a bug.
4430+
4431+=head1 FUNCTIONS
4432+
4433+=over 8
4434+
4435+=item _exit
4436+
4437+This is identical to the C function C<_exit()>. It exits the program
4438+immediately which means among other things buffered I/O is B<not> flushed.
4439+
4440+Note that when using threads and in Linux this is B<not> a good way to
4441+exit a thread because in Linux processes and threads are kind of the
4442+same thing (Note: while this is the situation in early 2003 there are
4443+projects under way to have threads with more POSIXly semantics in Linux).
4444+If you want not to return from a thread, detach the thread.
4445+
4446+=item abort
4447+
4448+This is identical to the C function C<abort()>. It terminates the
4449+process with a C<SIGABRT> signal unless caught by a signal handler or
4450+if the handler does not return normally (it e.g. does a C<longjmp>).
4451+
4452+=item abs
4453+
4454+This is identical to Perl's builtin C<abs()> function, returning
4455+the absolute value of its numerical argument.
4456+
4457+=item access
4458+
4459+Determines the accessibility of a file.
4460+
4461+ if( POSIX::access( "/", &POSIX::R_OK ) ){
4462+ print "have read permission\n";
4463+ }
4464+
4465+Returns C<undef> on failure. Note: do not use C<access()> for
4466+security purposes. Between the C<access()> call and the operation
4467+you are preparing for the permissions might change: a classic
4468+I<race condition>.
4469+
4470+=item acos
4471+
4472+This is identical to the C function C<acos()>, returning
4473+the arcus cosine of its numerical argument. See also L<Math::Trig>.
4474+
4475+=item alarm
4476+
4477+This is identical to Perl's builtin C<alarm()> function,
4478+either for arming or disarming the C<SIGARLM> timer.
4479+
4480+=item asctime
4481+
4482+This is identical to the C function C<asctime()>. It returns
4483+a string of the form
4484+
4485+ "Fri Jun 2 18:22:13 2000\n\0"
4486+
4487+and it is called thusly
4488+
4489+ $asctime = asctime($sec, $min, $hour, $mday, $mon, $year,
4490+ $wday, $yday, $isdst);
4491+
4492+The C<$mon> is zero-based: January equals C<0>. The C<$year> is
4493+1900-based: 2001 equals C<101>. C<$wday> and C<$yday> default to zero
4494+(and are usually ignored anyway), and C<$isdst> defaults to -1.
4495+
4496+=item asin
4497+
4498+This is identical to the C function C<asin()>, returning
4499+the arcus sine of its numerical argument. See also L<Math::Trig>.
4500+
4501+=item assert
4502+

4504+to achieve similar things.
4505+
4506+=item atan
4507+
4508+This is identical to the C function C<atan()>, returning the
4509+arcus tangent of its numerical argument. See also L<Math::Trig>.

4512+
4513+This is identical to Perl's builtin C<atan2()> function, returning
4514+the arcus tangent defined by its two numerical arguments, the I<y>
4515+coordinate and the I<x> coordinate. See also L<Math::Trig>.

4527+
4528+atoi() is C-specific. Perl converts strings to numbers transparently.

5401+for removing files, see L<perlfunc/unlink>.
5402+
5403+=item rename
5404+
5405+This is identical to Perl's builtin C<rename()> function
5406+for renaming files, see L<perlfunc/rename>.
5407+
5408+=item rewind
5409+
5410+Seeks to the beginning of the file.
5411+
5412+=item rewinddir
5413+
5414+This is identical to Perl's builtin C<rewinddir()> function for
5415+rewinding directory entry streams, see L<perlfunc/rewinddir>.
5416+
5417+=item rmdir
5418+
5419+This is identical to Perl's builtin C<rmdir()> function
5420+for removing (empty) directories, see L<perlfunc/rmdir>.
5421+
5422+=item scanf
5423+
5424+scanf() is C-specific, use E<lt>E<gt> and regular expressions instead,
5425+see L<perlre>.
5426+
5427+=item setgid
5428+
5429+Sets the real group identifier and the effective group identifier for
5430+this process. Similar to assigning a value to the Perl's builtin
5431+C<$)> variable, see L<perlvar/$EGID>, except that the latter
5432+will change only the real user identifier, and that the setgid()
5433+uses only a single numeric argument, as opposed to a space-separated
5434+list of numbers.
5435+
5436+=item setjmp
5437+
5438+C<setjmp()> is C-specific: use C<eval {}> instead,
5439+see L<perlfunc/eval>.
5440+
5441+=item setlocale
5442+
5443+Modifies and queries program's locale. The following examples assume
5444+
5445+ use POSIX qw(setlocale LC_ALL LC_CTYPE);
5446+
5447+has been issued.
5448+
5449+The following will set the traditional UNIX system locale behavior
5450+(the second argument C<"C">).
5451+
5452+ $loc = setlocale( LC_ALL, "C" );
5453+
5454+The following will query the current LC_CTYPE category. (No second
5455+argument means 'query'.)
5456+
5457+ $loc = setlocale( LC_CTYPE );
5458+
5459+The following will set the LC_CTYPE behaviour according to the locale
5460+environment variables (the second argument C<"">).
5461+Please see your systems C<setlocale(3)> documentation for the locale
5462+environment variables' meaning or consult L<perllocale>.
5463+
5464+ $loc = setlocale( LC_CTYPE, "" );
5465+
5466+The following will set the LC_COLLATE behaviour to Argentinian
5467+Spanish. B<NOTE>: The naming and availability of locales depends on
5468+your operating system. Please consult L<perllocale> for how to find
5469+out which locales are available in your system.
5470+
5471+ $loc = setlocale( LC_COLLATE, "es_AR.ISO8859-1" );
5472+
5473+=item setpgid
5474+
5475+This is similar to the C function C<setpgid()> for
5476+setting the process group identifier of the current process.
5477+
5478+Returns C<undef> on failure.
5479+
5480+=item setsid
5481+
5482+This is identical to the C function C<setsid()> for
5483+setting the session identifier of the current process.
5484+
5485+=item setuid
5486+
5487+Sets the real user identifier and the effective user identifier for
5488+this process. Similar to assigning a value to the Perl's builtin
5489+C<$E<lt>> variable, see L<perlvar/$UID>, except that the latter
5490+will change only the real user identifier.
5491+
5492+=item sigaction
5493+
5494+Detailed signal management. This uses C<POSIX::SigAction> objects for
5495+the C<action> and C<oldaction> arguments (the oldaction can also be
5496+just a hash reference). Consult your system's C<sigaction> manpage
5497+for details, see also C<POSIX::SigRt>.
5498+
5499+Synopsis:
5500+
5501+ sigaction(signal, action, oldaction = 0)
5502+
5503+Returns C<undef> on failure. The C<signal> must be a number (like
5504+SIGHUP), not a string (like "SIGHUP"), though Perl does try hard
5505+to understand you.
5506+
5507+If you use the SA_SIGINFO flag, the signal handler will in addition to
5508+the first argument, the signal name, also receive a second argument, a
5509+hash reference, inside which are the following keys with the following
5510+semantics, as defined by POSIX/SUSv3:
5511+
5512+ signo the signal number
5513+ errno the error number
5514+ code if this is zero or less, the signal was sent by
5515+ a user process and the uid and pid make sense,
5516+ otherwise the signal was sent by the kernel
5517+
5518+The following are also defined by POSIX/SUSv3, but unfortunately
5519+not very widely implemented:
5520+
5521+ pid the process id generating the signal
5522+ uid the uid of the process id generating the signal
5523+ status exit value or signal for SIGCHLD
5524+ band band event for SIGPOLL
5525+
5526+A third argument is also passed to the handler, which contains a copy
5527+of the raw binary contents of the siginfo structure: if a system has
5528+some non-POSIX fields, this third argument is where to unpack() them
5529+from.
5530+
5531+Note that not all siginfo values make sense simultaneously (some are
5532+valid only for certain signals, for example), and not all values make
5533+sense from Perl perspective, you should to consult your system's
5534+C<sigaction> and possibly also C<siginfo> documentation.
5535+
5536+=item siglongjmp
5537+
5538+siglongjmp() is C-specific: use L<perlfunc/die> instead.
5539+
5540+=item sigpending
5541+
5542+Examine signals that are blocked and pending. This uses C<POSIX::SigSet>
5543+objects for the C<sigset> argument. Consult your system's C<sigpending>
5544+manpage for details.
5545+
5546+Synopsis:
5547+
5548+ sigpending(sigset)
5549+
5550+Returns C<undef> on failure.
5551+
5552+=item sigprocmask
5553+
5554+Change and/or examine calling process's signal mask. This uses
5555+C<POSIX::SigSet> objects for the C<sigset> and C<oldsigset> arguments.
5556+Consult your system's C<sigprocmask> manpage for details.
5557+
5558+Synopsis:
5559+
5560+ sigprocmask(how, sigset, oldsigset = 0)
5561+
5562+Returns C<undef> on failure.
5563+
5564+=item sigsetjmp
5565+
5566+C<sigsetjmp()> is C-specific: use C<eval {}> instead,
5567+see L<perlfunc/eval>.
5568+
5569+=item sigsuspend
5570+
5571+Install a signal mask and suspend process until signal arrives. This uses
5572+C<POSIX::SigSet> objects for the C<signal_mask> argument. Consult your
5573+system's C<sigsuspend> manpage for details.
5574+
5575+Synopsis:
5576+
5577+ sigsuspend(signal_mask)
5578+
5579+Returns C<undef> on failure.
5580+
5581+=item sin
5582+
5583+This is identical to Perl's builtin C<sin()> function
5584+for returning the sine of the numerical argument,
5585+see L<perlfunc/sin>. See also L<Math::Trig>.
5586+
5587+=item sinh
5588+
5589+This is identical to the C function C<sinh()>
5590+for returning the hyperbolic sine of the numerical argument.
5591+See also L<Math::Trig>.
5592+
5593+=item sleep
5594+
5595+This is functionally identical to Perl's builtin C<sleep()> function
5596+for suspending the execution of the current for process for certain
5597+number of seconds, see L<perlfunc/sleep>. There is one significant
5598+difference, however: C<POSIX::sleep()> returns the number of
5599+B<unslept> seconds, while the C<CORE::sleep()> returns the
5600+number of slept seconds.
5601+
5602+=item sprintf
5603+
5604+This is similar to Perl's builtin C<sprintf()> function
5605+for returning a string that has the arguments formatted as requested,
5606+see L<perlfunc/sprintf>.
5607+
5608+=item sqrt
5609+
5610+This is identical to Perl's builtin C<sqrt()> function.
5611+for returning the square root of the numerical argument,
5612+see L<perlfunc/sqrt>.
5613+
5614+=item srand
5615+
5616+Give a seed the pseudorandom number generator, see L<perlfunc/srand>.
5617+
5618+=item sscanf
5619+
5620+sscanf() is C-specific, use regular expressions instead,
5621+see L<perlre>.
5622+
5623+=item stat
5624+
5625+This is identical to Perl's builtin C<stat()> function
5626+for returning information about files and directories.
5627+
5628+=item strcat
5629+
5630+strcat() is C-specific, use C<.=> instead, see L<perlop>.
5631+
5632+=item strchr
5633+
5634+strchr() is C-specific, see L<perlfunc/index> instead.
5635+
5636+=item strcmp
5637+
5638+strcmp() is C-specific, use C<eq> or C<cmp> instead, see L<perlop>.
5639+
5640+=item strcoll
5641+
5642+This is identical to the C function C<strcoll()>
5643+for collating (comparing) strings transformed using
5644+the C<strxfrm()> function. Not really needed since
5645+Perl can do this transparently, see L<perllocale>.
5646+
5647+=item strcpy
5648+
5649+strcpy() is C-specific, use C<=> instead, see L<perlop>.
5650+
5651+=item strcspn
5652+
5653+strcspn() is C-specific, use regular expressions instead,
5654+see L<perlre>.
5655+
5656+=item strerror
5657+
5658+Returns the error string for the specified errno.
5659+Identical to the string form of the C<$!>, see L<perlvar/$ERRNO>.
5660+
5661+=item strftime
5662+
5663+Convert date and time information to string. Returns the string.
5664+
5665+Synopsis:
5666+
5667+ strftime(fmt, sec, min, hour, mday, mon, year, wday = -1, yday = -1, isdst = -1)
5668+
5669+The month (C<mon>), weekday (C<wday>), and yearday (C<yday>) begin at zero.
5670+I.e. January is 0, not 1; Sunday is 0, not 1; January 1st is 0, not 1. The
5671+year (C<year>) is given in years since 1900. I.e., the year 1995 is 95; the
5672+year 2001 is 101. Consult your system's C<strftime()> manpage for details
5673+about these and the other arguments.
5674+
5675+If you want your code to be portable, your format (C<fmt>) argument
5676+should use only the conversion specifiers defined by the ANSI C
5677+standard (C89, to play safe). These are C<aAbBcdHIjmMpSUwWxXyYZ%>.
5678+But even then, the B<results> of some of the conversion specifiers are
5679+non-portable. For example, the specifiers C<aAbBcpZ> change according
5680+to the locale settings of the user, and both how to set locales (the
5681+locale names) and what output to expect are non-standard.
5682+The specifier C<c> changes according to the timezone settings of the
5683+user and the timezone computation rules of the operating system.
5684+The C<Z> specifier is notoriously unportable since the names of
5685+timezones are non-standard. Sticking to the numeric specifiers is the
5686+safest route.
5687+
5688+The given arguments are made consistent as though by calling
5689+C<mktime()> before calling your system's C<strftime()> function,
5690+except that the C<isdst> value is not affected.
5691+
5692+The string for Tuesday, December 12, 1995.
5693+
5694+ $str = POSIX::strftime( "%A, %B %d, %Y", 0, 0, 0, 12, 11, 95, 2 );
5695+ print "$str\n";
5696+
5697+=item strlen
5698+
5699+strlen() is C-specific, use C<length()> instead, see L<perlfunc/length>.
5700+
5701+=item strncat
5702+
5703+strncat() is C-specific, use C<.=> instead, see L<perlop>.
5704+
5705+=item strncmp
5706+
5707+strncmp() is C-specific, use C<eq> instead, see L<perlop>.
5708+
5709+=item strncpy
5710+
5711+strncpy() is C-specific, use C<=> instead, see L<perlop>.
5712+
5713+=item strpbrk
5714+
5715+strpbrk() is C-specific, use regular expressions instead,
5716+see L<perlre>.
5717+
5718+=item strrchr
5719+
5720+strrchr() is C-specific, see L<perlfunc/rindex> instead.
5721+
5722+=item strspn
5723+
5724+strspn() is C-specific, use regular expressions instead,
5725+see L<perlre>.
5726+
5727+=item strstr
5728+
5729+This is identical to Perl's builtin C<index()> function,
5730+see L<perlfunc/index>.
5731+
5732+=item strtod
5733+
5734+String to double translation. Returns the parsed number and the number
5735+of characters in the unparsed portion of the string. Truly
5736+POSIX-compliant systems set $! ($ERRNO) to indicate a translation
5737+error, so clear $! before calling strtod. However, non-POSIX systems
5738+may not check for overflow, and therefore will never set $!.
5739+
5740+strtod should respect any POSIX I<setlocale()> settings.
5741+
5742+To parse a string $str as a floating point number use
5743+
5744+ $! = 0;
5745+ ($num, $n_unparsed) = POSIX::strtod($str);
5746+
5747+The second returned item and $! can be used to check for valid input:
5748+
5749+ if (($str eq '') || ($n_unparsed != 0) || $!) {
5750+ die "Non-numeric input $str" . ($! ? ": $!\n" : "\n");
5751+ }
5752+
5753+When called in a scalar context strtod returns the parsed number.
5754+
5755+=item strtok
5756+
5757+strtok() is C-specific, use regular expressions instead, see
5758+L<perlre>, or L<perlfunc/split>.
5759+
5760+=item strtol
5761+
5762+String to (long) integer translation. Returns the parsed number and
5763+the number of characters in the unparsed portion of the string. Truly
5764+POSIX-compliant systems set $! ($ERRNO) to indicate a translation
5765+error, so clear $! before calling strtol. However, non-POSIX systems
5766+may not check for overflow, and therefore will never set $!.
5767+
5768+strtol should respect any POSIX I<setlocale()> settings.
5769+
5770+To parse a string $str as a number in some base $base use
5771+
5772+ $! = 0;
5773+ ($num, $n_unparsed) = POSIX::strtol($str, $base);
5774+
5775+The base should be zero or between 2 and 36, inclusive. When the base
5776+is zero or omitted strtol will use the string itself to determine the
5777+base: a leading "0x" or "0X" means hexadecimal; a leading "0" means
5778+octal; any other leading characters mean decimal. Thus, "1234" is
5779+parsed as a decimal number, "01234" as an octal number, and "0x1234"
5780+as a hexadecimal number.
5781+
5782+The second returned item and $! can be used to check for valid input:
5783+
5784+ if (($str eq '') || ($n_unparsed != 0) || !$!) {
5785+ die "Non-numeric input $str" . $! ? ": $!\n" : "\n";
5786+ }
5787+
5788+When called in a scalar context strtol returns the parsed number.
5789+
5790+=item strtoul
5791+
5792+String to unsigned (long) integer translation. strtoul() is identical
5793+to strtol() except that strtoul() only parses unsigned integers. See
5794+L</strtol> for details.
5795+
5796+Note: Some vendors supply strtod() and strtol() but not strtoul().
5797+Other vendors that do supply strtoul() parse "-1" as a valid value.
5798+
5799+=item strxfrm
5800+
5801+String transformation. Returns the transformed string.
5802+
5803+ $dst = POSIX::strxfrm( $src );
5804+
5805+Used in conjunction with the C<strcoll()> function, see L</strcoll>.
5806+
5807+Not really needed since Perl can do this transparently, see
5808+L<perllocale>.
5809+
5810+=item sysconf
5811+
5812+Retrieves values of system configurable variables.
5813+
5814+The following will get the machine's clock speed.
5815+
5816+ $clock_ticks = POSIX::sysconf( &POSIX::_SC_CLK_TCK );
5817+
5818+Returns C<undef> on failure.
5819+
5820+=item system
5821+

5828+tangent of the numerical argument. See also L<Math::Trig>.
5829+
5830+=item tanh
5831+
5832+This is identical to the C function C<tanh()>, returning the
5833+hyperbolic tangent of the numerical argument. See also L<Math::Trig>.
5834+
5835+=item tcdrain
5836+
5837+This is similar to the C function C<tcdrain()> for draining
5838+the output queue of its argument stream.
5839+
5840+Returns C<undef> on failure.
5841+
5842+=item tcflow
5843+
5844+This is similar to the C function C<tcflow()> for controlling
5845+the flow of its argument stream.
5846+
5847+Returns C<undef> on failure.
5848+
5849+=item tcflush
5850+
5851+This is similar to the C function C<tcflush()> for flushing
5852+the I/O buffers of its argument stream.
5853+
5854+Returns C<undef> on failure.
5855+
5856+=item tcgetpgrp
5857+
5858+This is identical to the C function C<tcgetpgrp()> for returning the
5859+process group identifier of the foreground process group of the controlling
5860+terminal.
5861+
5862+=item tcsendbreak
5863+
5864+This is similar to the C function C<tcsendbreak()> for sending
5865+a break on its argument stream.
5866+
5867+Returns C<undef> on failure.
5868+
5869+=item tcsetpgrp
5870+
5871+This is similar to the C function C<tcsetpgrp()> for setting the
5872+process group identifier of the foreground process group of the controlling
5873+terminal.
5874+
5875+Returns C<undef> on failure.
5876+
5877+=item time
5878+
5879+This is identical to Perl's builtin C<time()> function
5880+for returning the number of seconds since the epoch
5881+(whatever it is for the system), see L<perlfunc/time>.
5882+
5883+=item times
5884+
5885+The times() function returns elapsed realtime since some point in the past
5886+(such as system startup), user and system times for this process, and user
5887+and system times used by child processes. All times are returned in clock
5888+ticks.
5889+
5890+ ($realtime, $user, $system, $cuser, $csystem) = POSIX::times();
5891+
5892+Note: Perl's builtin C<times()> function returns four values, measured in
5893+seconds.
5894+
5895+=item tmpfile
5896+
5897+Use method C<IO::File::new_tmpfile()> instead, or see L<File::Temp>.
5898+
5899+=item tmpnam
5900+
5901+Returns a name for a temporary file.
5902+
5903+ $tmpfile = POSIX::tmpnam();
5904+
5905+For security reasons, which are probably detailed in your system's
5906+documentation for the C library tmpnam() function, this interface
5907+should not be used; instead see L<File::Temp>.
5908+
5909+=item tolower
5910+
5911+This is identical to the C function, except that it can apply to a single
5912+character or to a whole string. Consider using the C<lc()> function,
5913+see L<perlfunc/lc>, or the equivalent C<\L> operator inside doublequotish
5914+strings.
5915+
5916+=item toupper
5917+
5918+This is identical to the C function, except that it can apply to a single
5919+character or to a whole string. Consider using the C<uc()> function,
5920+see L<perlfunc/uc>, or the equivalent C<\U> operator inside doublequotish
5921+strings.
5922+
5923+=item ttyname
5924+
5925+This is identical to the C function C<ttyname()> for returning the
5926+name of the current terminal.
5927+
5928+=item tzname
5929+
5930+Retrieves the time conversion information from the C<tzname> variable.
5931+
5932+ POSIX::tzset();
5933+ ($std, $dst) = POSIX::tzname();
5934+
5935+=item tzset
5936+

6069+
6070+accessor function for the "safe signals" flag of a SigAction object; see

6072+you wish to handle a signal safely, use this accessor to set the "safe" flag
6073+in the C<POSIX::SigAction> object:
6074+
6075+ $sigaction->safe(1);
6076+
6077+You may also examine the "safe" flag on the output action object which is
6078+filled in when given as the third parameter to C<POSIX::sigaction()>:
6079+
6080+ sigaction(SIGINT, $new_action, $old_action);

6088+
6089+=over 8
6090+
6091+=item %SIGRT
6092+
6093+A hash of the POSIX realtime signal handlers. It is an extension of
6094+the standard %SIG, the $POSIX::SIGRT{SIGRTMIN} is roughly equivalent
6095+to $SIG{SIGRTMIN}, but the right POSIX moves (see below) are made with
6096+the POSIX::SigSet and POSIX::sigaction instead of accessing the %SIG.
6097+
6098+You can set the %POSIX::SIGRT elements to set the POSIX realtime
6099+signal handlers, use C<delete> and C<exists> on the elements, and use
6100+C<scalar> on the C<%POSIX::SIGRT> to find out how many POSIX realtime
6101+signals there are available (SIGRTMAX - SIGRTMIN + 1, the SIGRTMAX is
6102+a valid POSIX realtime signal).
6103+
6104+Setting the %SIGRT elements is equivalent to calling this:
6105+
6106+ sub new {
6107+ my ($rtsig, $handler, $flags) = @_;
6108+ my $sigset = POSIX::SigSet($rtsig);
6109+ my $sigact = POSIX::SigAction->new($handler, $sigset, $flags);
6110+ sigaction($rtsig, $sigact);
6111+ }
6112+
6113+The flags default to zero, if you want something different you can
6114+either use C<local> on $POSIX::SigRt::SIGACTION_FLAGS, or you can
6115+derive from POSIX::SigRt and define your own C<new()> (the tied hash
6116+STORE method of the %SIGRT calls C<new($rtsig, $handler, $SIGACTION_FLAGS)>,
6117+where the $rtsig ranges from zero to SIGRTMAX - SIGRTMIN + 1).
6118+
6119+Just as with any signal, you can use sigaction($rtsig, undef, $oa) to
6120+retrieve the installed signal handler (or, rather, the signal action).
6121+
6122+B<NOTE:> whether POSIX realtime signals really work in your system, or
6123+whether Perl has been compiled so that it works with them, is outside
6124+of this discussion.
