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 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.
