killpg
KILLPG(2) BSD 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.
SEE ALSO getpgrp(2), kill(2), sigaction(2)HISTORY
The killpg() function appeared in 4.0BSD.
