KILLPG(2)		  FreeBSD System Calls Manual		     KILLPG(2)

NAME
     killpg -- send signal to a	process	group

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <signal.h>

     int
     killpg(pid_t pgrp,	int sig);

DESCRIPTION
     The killpg() function sends the signal sig	to the process group pgrp.
     See sigaction(2) for a list of signals.  If pgrp is 0, killpg() sends the
     signal to the sending process's process group.

     The sending process must be able to kill()	at least one process in	the
     receiving process group.

RETURN VALUES
     The killpg() function returns the value 0 if successful; otherwise	the
     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     The killpg() function will	fail and no signal will	be sent	if:

     [EINVAL]		The sig	argument is not	a valid	signal number.

     [ESRCH]		No process can be found	in the process group specified
			by pgrp.

     [EPERM]		kill() returns EPERM for all processes in the process
			group.
