SYNOPSIS

       #include <signal.h>

       int killpg(pid_t pgrp, int sig);

DESCRIPTION

       The  killpg()  function  shall  send  the  signal  specified  by  sig to the process group
       specified by pgrp.

       If pgrp is greater than 1, killpg(pgrp, sig) shall be equivalent to  kill(-pgrp, sig).  If
