p5-Proc-Wait3

Perl extension for wait3 system call

Proc::Wait3 module implements wait3 system call in Perl. If any child processes have exited, this call will "reap" the zombies similar to the perl "wait" function. By default, it will return immediately and if there are no dead children, everything will be undefined. If you pass in a true argument, it will block until a child exits (or it gets a signal).
