.TH GETSOCKNAME 2 "18 Mai 1999" Linux "Manuel du programmeur Linux"
.SH NOM
getsockname \- Obtenir le nom d'une socket.
.SH SYNOPSIS
.B #include <sys/socket.h>
.sp
.B "int getsockname(int " s ", struct sockaddr *" name ", socklen_t *" namelen )
.SH DESCRIPTION
.B Getsockname
renvoie le nom
.I name
de la socket indique. Le paramtre
.I namelen
doit tre initialis pour indiquer la taille de la zone mmoire
pointe par
.IR name .
En retour, il contiendra la taille effective (en octets) du
nom renvoy.
.SH "VALEUR RENVOYE"
.BR getsockname
renvoie 0 s'il russit, ou \-1 s'il choue, auquel cas
.I errno
contient le code d'erreur.
.SH ERREURS
.TP 0.8i
.B EBADF
L'argument
.I s
n'est pas un descripteur valide.
.TP
.B ENOTSOCK
L'argument
.I s
est un fichier, pas une socket.
.TP
.B ENOBUFS
Pas assez de mmoire pour le noyau
.TP
.B EFAULT
.I name
pointe en dehors de l'espace d'adressage accessible.
.SH CONFORMIT
SVr4, BSD 4.4 (la fonction
.B getsockname
est apparue dans BSD 4.2). SVr4 documente des conditions d'erreur
ENOMEM et ENOSR supplmentaires.
.SH NOTE
Le troisime argument de
.B getsockname
est en fait un int (et c'est ce qu'utilisent BSD 4.*, libc4 et libc5).
Une certaine confusion POSIX rsulte du "socklen_t" actuel. Les propositions
de standard n'ont pas encore t adoptes, mais glibc2 les suit dj et
utilise socklen_t. Pour plus de dtails voir
.BR accept (2).
.SH "VOIR AUSSI"
.BR bind "(2), " socket (2)
