NAME

Proc::Wait3 - Perl extension for wait3 system call

SYNOPSIS

use Proc::Wait3;

($pid, $status, $utime, $stime, $maxrss, $ixrss, $idrss, $isrss,
$minflt, $majflt, $nswap, $inblock, $oublock, $msgsnd, $msgrcv,
$nsignals, $nvcsw, $nivcsw) = wait3();

DESCRIPTION

If any child processes have exited, this call will "reap" the zombies similar to the perl "wait" function.

If there are no dead children, everything will be undefined.

$pid         PID of exiting child

$status      exit status of child, just like C<$?>

$utime       floating point user cpu seconds

$stime       floating point system cpu seconds

$maxrss      the maximum resident set size utilized (in kilobytes).

$minflt      the number of page faults serviced without any I/O
             activity; here I/O activity is avoided by "reclaiming" a
             page frame from the list of pages awaiting reallocation.

$majflt      the number of page faults serviced that required I/O
             activity.

$nswap       the number of times a process was "swapped" out of main
             memory.

$inblock     the number of times the file system had to perform input.

$oublock     the number of times the file system had to perform output.

$msgsnd      the number of messages sent over sockets.

$msgrcv      the number of messages received from sockets.

$nsignals    the number of signals delivered.

$nvcsw       the number of times a context switch resulted due to a
             process voluntarily giving up the processor before its
             time slice was completed (usually to await availability of
             a resource).

$nivcsw      the number of times a context switch resulted due to a
             higher priority process becoming runnable or because the
             current process exceeded its time slice.
