Does that not work on a stopped process? I've tried to kill a stopped process and it is not working. Or do you need a certain type of shell for this to work? I don't see anything about this in my man pages. (3 Replies)

killpg
KILLPG(3) Linux Programmer's Manual KILLPG(3)NAME
killpg - send signal to a process group
SYNOPSIS
#include <signal.h>
int killpg(int pgrp, int sig);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
killpg():
_XOPEN_SOURCE >= 500
|| /* Since glibc 2.19: */ _DEFAULT_SOURCE
|| /* Glibc versions <= 2.19: */ _BSD_SOURCE
DESCRIPTION
killpg() sends the signal sig to the process group pgrp. See signal(7) for a list of signals.
If pgrp is 0, killpg() sends the signal to the calling process's process group. (POSIX says: if pgrp is less than or equal to 1, the
behavior is undefined.)
For the permissions required to send a signal to another process, see kill(2).
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
ERRORS
EINVAL sig is not a valid signal number.
EPERM The process does not have permission to send the signal to any of the target processes. For the required permissions, see kill(2).
ESRCH No process can be found in the process group specified by pgrp.
ESRCH The process group was given as 0 but the sending process does not have a process group.
CONFORMING TO
POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD (killpg() first appeared in 4BSD).
NOTES
There are various differences between the permission checking in BSD-type systems and System V-type systems. See the POSIX rationale for
kill(). A difference not mentioned by POSIX concerns the return value EPERM: BSD documents that no signal is sent and EPERM returned when
the permission check failed for at least one target process, while POSIX documents EPERM only when the permission check failed for all tar-
get processes.
C library/kernel differences
On Linux, killpg() is implemented as a library function that makes the call kill(-pgrp, sig).
