Manual Reference Pages - LIBOWFAT_SOCKET_BROADCAST (3)
socket_broadcast - set UDP socket to broadcast mode
int socket_broadcast(int s);
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
strerr_die2sys(111,FATAL,"unable to create UDP socket: ");
if (socket_broadcast(s) == -1)
strerr_die2sys(111,FATAL,"unable to set broadcast mode: ");
