NAME

socket_broadcast - set UDP socket to broadcast mode

SYNTAX

#include <libowfat/socket.h>

int socket_broadcast(int s);

DESCRIPTION

socket_broadcast sets UDP socket s to broadcast mode. socket_send4 and socket_send6 will fail to send packets to the broadcast address unless socket_broadcast is called before.

Normally socket_broadcast returns 0.

If anything goes wrong, socket_broadcast returns -1, setting errno appropriately.

EXAMPLE

#include <libowfat/socket.h>

int s;

if ((s=socket_udp6())==-1) strerr_die2sys(111,FATAL,"unable to create UDP socket: "); if (socket_broadcast(s) == -1) strerr_die2sys(111,FATAL,"unable to set broadcast mode: ");
