killpg(3)

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 target
       processes.

   C library/kernel differences
       On Linux, killpg() is implemented as a library function that makes  the
       call kill(-pgrp, sig).
