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  effect  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);
