+WaitOnConnect returns TRUE if the connection request completes. This
+does not necessarily mean that the connection was succesfully established;
+it might also happen that the connection was refused by the peer. Use
+\helpref{IsConnected}{wxsocketbaseisconnected} to distinguish between

+
+If the timeout elapses, WaitOnConnect returns FALSE.
+
+These semantics allow code like this:
-If the timeout expires, or if the connection fails, returns FALSE.
