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 pro-
       cesses 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 following:

       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.
