PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-

       Linux.

NAME

       If pgrp is greater than 1, killpg(pgrp, sig) shall be equivalent to kill(-pgrp, sig). If pgrp is less than or equal to 1,
       the behavior of killpg() is undefined.
