NAME

       socket_connect4 - attempt to make a TCP connection

SYNTAX

       #include <socket.h>

       int socket_connect4(int s,const char ip[4],uint16 port);

DESCRIPTION

       socket_connect4  attempts  to  make  a connection from TCP socket s to TCP port port on IP
       address ip.

       socket_connect4 may return

       •      0, to indicate that the connection succeeded (and  succeeded  immediately,  if  the
              socket is non-blocking)

       •      -1,  setting  errno  to  error_inprogress or error_wouldblock, to indicate that the
              socket is non-blocking

       •      -1, setting errno to something else, to indicate that the  connection  failed  (and
              failed immediately, if the socket is non-blocking).

       When  a  background  connection  succeeds  or  fails,  s  becomes  writable;  you  can use
       socket_connected to see whether the  connection  succeeded.   If  the  connection  failed,
       socket_connected returns 0, setting errno appropriately.

       Once  a  TCP  socket is connected, you can use the read and write system calls to transmit
       data.

       You can call socket_connect4 without calling socket_bind4.  This has the effect  as  first
       calling socket_bind4 with IP address 0.0.0.0 and port 0.

EXAMPLE

         #include <socket.h>

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

         s = socket_tcp4();
         socket_bind4(s,ip,p);
         socket_connect4(s,ip,p);
