       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

       propriately.

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: ");
