NAME
       socket_broadcast - set UDP socket to broadcast mode

SYNTAX
       #include <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 <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: ");
