NAME

6       socket_broadcast - set UDP socket to broadcast mode
7

SYNTAX

9       #include <socket.h>
10
11       int socket_broadcast(int s);
12

DESCRIPTION

14       socket_broadcast sets UDP socket s to broadcast mode.  socket_send4 and
15       socket_send6 will fail to send packets to the broadcast address  unless
16       socket_broadcast is called before.
17
18       Normally socket_broadcast returns 0.
19
20       If  anything  goes  wrong,  socket_broadcast  returns -1, setting errno
21       appropriately.

EXAMPLE

25         #include <socket.h>
26
27         int s;
28
29         if ((s=socket_udp6())==-1)
30           strerr_die2sys(111,FATAL,"unable to create UDP socket: ");
31         if (socket_broadcast(s) == -1)
32           strerr_die2sys(111,FATAL,"unable to set broadcast mode: ");
