NAME
       killpg - send signal to all members of a process group.

SYNOPSIS
       #include <signal.h>

       int killpg(pid_t pidgrp, int signal);

DESCRIPTION
       The  killpg()  function causes signal signal to be sent to
       all the processes in the process group pidgrp  or  to  the
       processes' own process group if pidgrp is equal to zero.

       It is equivalent to

       kill(-pidgrp,signal);

RETURN VALUE
       The value returned is -1 on error, or 0 for success.

ERRORS
       Errors are returned in errno and can be one of the follow-
       ing:

       EINVAL for an invalid signal,

       ESRCH  for a process group which does not exist, and

       EPERM  if the userid of the calling process is  not  equal
              to  that  of the process the signal is sent to, and
              the userid is not that of the superuser.
