.SH NOM
killpg \- Envoyer un signal a un groupe de processus.
.SH SYNOPSIS
.B #include <signal.h>
.sp
.BI "int killpg(int " pgrp ", int " sig );
.SH DESCRIPTION
.B Killpg
envoie le signal
.I sig
au groupe de processus
.IR pgrp.
Voir

vaut 0,
.B killpg
envoie le signal au groupe de processus du processus appelant.
Le processus appelant et les membres du groupe de processus
destinataire doivent avoir le meme UID effectif, ou l'appelant
doit etre le Super\-User.
La seule exception est le signal de continuation
.B SIGCONT
qui peut etre emis vers n'importe quel processus descendant de l'appelant.
.SH "VALEUR RENVOYEE"
.BR killpg
renvoie 0 si il reussit, ou \-1 s'il echoue, auquel cas
.I errno
contient le code d'erreur.
.SH ERREURS
.TP
.B EINVAL
.I Sig
n'est pas un numero de signal valide.
.TP
.B ESRCH
Aucun processus n'appartient au groupe
.IR pgrp .
.TP
.B ESRCH
On a voulu emettre vers le groupe 0, mais le processus en cours
n'appartient pas a un groupe.
.TP
.B EPERM
L'appelant n'est pas le Super\-User, et il y a au moins un processus
du groupe destinataire dont l'UID effectif ne correspond pas a celui
de l'appelant.
