POSIX::1003::Proc - POSIX handling processes
POSIX::1003::Proc is a POSIX::1003::Module
use POSIX::1003::Proc qw/abort setpgid/; abort(); setpgid($pid, $pgid);
Functions which are bound to each separate process.
Abnormal process exit.
These functions have captial names because in C they are implemented as macro's (which are capitalized by convension)
Returns the normal exit status of the child process. Only meaningful if
WIFEXITED($?) is true.
Returns true if the child process exited normally: "exit()" or by falling off the end of "main()".
Returns true if the child process terminated because of a signal.
Returns true if the child process is currently stopped. Can happen only if you specified the
WUNTRACED flag to waitpid().
Returns the signal the child process was stopped for. Only meaningful if
WIFSTOPPED($?) is true.
Returns the signal the child process terminated for. Only meaningful if
WIFSIGNALED($?) is true.
Simply "wait" in perlfunc.
Simply "waitpid" in perlfunc.
Leave the program without calling handlers registered with
atexit (which is not available in Perl)
Generates the path name for the controlling terminal of this process. my $path = ctermid();
Get the login name of the effective user of the current process. See also
perldoc -f getlogin my $name = cuserid();
Returns the name of the current working directory. See also Cwd.
use POSIX::1003::Proc 'nice'; $new_prio = nice($increment);
times() function returns four values, conveniently converted into seconds (float). The POSIX
times() returns five values in clocktics. To disambique those two, we offer the POSIX function under a slightly different name.
($user, $sys, $cuser, $csys) = CORE::times(); ($elapse, $user, $sys, $cuser, $csys) = POSIX::times(); ($elapse, $user, $sys, $cuser, $csys) = times5();
