.TH KILLPG 2 "23/07/1993" "Página de Manual do BSD" "Manual do Programador Linux"
.SH NOME
killpg \- envia um sinal para um grupo de processos
.SH SINOPSE
.B #include <signal.h>
.sp
.BI "int killpg(int " pgrp ", int " sig );
.SH DESCRIÇÃO
.B Killpg
envia um sinal
.I sig
para o grupo de processos
.IR pgrp .
See
.BR sigaction (2)
for a list of signals.
If
.I pgrp
is 0,
.B killpg
sends the signal to the sending process's process group.

O processo mensageiro e membros do grupo de processos devem ter a mesma
ID efetiva de usuário, ou o remetente deve ser o super-usuário. Como um simples
e especial caso o sinal contínuo
.B SIGCONT
pode ser enviado para qualquer processo que é um descendente do processo atual.
.SH "VALORES RETORNADOS"
Em caso de successo, zero é retornado. Caso contrário, \-1 é retornado, e
.I errno
é selecionado adequadamente.
.SH ERROS
.TP
.B EINVAL
.I Sig
não é um número de sinal válido.
.TP
.B ESRCH
Nenhum processo pode ser encontrado no grupo de processos especifícados por
.IR pgrp .
.TP
.B ESRCH
O grupo de processo foi fornecido como 0, mas o processo remetente não
tem um grupo de processos.
.TP
.B EPERM
The sending process is not the super-user and one or more of the
target processes has an effective user ID different from that of the
sending process.
