socket_send4(3) 	    Library Functions Manual		 socket_send4(3)

NAME
     socket_send4 - send a UDP datagram

SYNTAX
     #include <libowfat/socket.h>

     ssize_t socket_send4(int s, const char* buf, size_t len,
			  const char ip[4],uint16 port);

DESCRIPTION
     socket_send4  sends  len  bytes  starting at buf in a UDP datagram over the
     socket s to UDP port port on IP address ip.

     You can call socket_send4 without calling socket_bind4.  This has	the  ef-
     fect as first calling socket_bind4 with IP address 0.0.0.0 and port 0.

RETURN VALUE
     socket_send4  returns  0 if the datagram was sent successfully.  If not, it
     returns -1 and sets errno appropriately.

EXAMPLE
       #include <libowfat/socket.h>

       int s;
       char ip[4];
       uint16 p;

       s = socket_tcp4();
       socket_bind4(s,ip,p);
       socket_send4(s,"hello, world",12,ip,p);
