/* GSocket_Connect:
* For stream (connection oriented) sockets, GSocket_Connect() tries
* to establish a client connection to a server using the peer address
* as established with GSocket_SetPeer(). Returns GSOCK_NOERROR if the
* connection has been successfully established, or one of the error
* codes listed below. Note that for nonblocking sockets, a return
* value of GSOCK_WOULDBLOCK doesn't mean a failure. The connection
* request can be completed later; you should use GSocket_Select()
* to poll for GSOCK_CONNECTION | GSOCK_LOST, or wait for the
* corresponding asynchronous events.
*
* For datagram (non connection oriented) sockets, GSocket_Connect()
* just sets the peer address established with GSocket_SetPeer() as
* default destination.
*
* Error codes:
* GSOCK_INVSOCK - the socket is in use or not valid.
* GSOCK_INVADDR - the peer address has not been established.
* GSOCK_TIMEDOUT - timeout, the connection failed.
* GSOCK_WOULDBLOCK - connection in progress (nonblocking sockets only)
* GSOCK_MEMERR - couldn't allocate memory.
* GSOCK_IOERR - low-level error.
