socket_broadcast(3)	    Library Functions Manual	     socket_broadcast(3)

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 appro-
     priately.

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: ");
