socket_broadcast - set UDP socket to broadcast mode
#include <socket.h> 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 appropriately.
#include <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: ");
socket_send4(3), socket_send6(3) socket_broadcast(3)
