// Mini-tutorial for Connect() :-)
// ---------------------------
//
// There are two ways to use Connect(): blocking and non-blocking,
// depending on the value passed as the 'wait' (2nd) parameter.
//
// Connect(addr, TRUE) will wait until the connection completes,
// returning TRUE on success and FALSE on failure. This call blocks
// the GUI (this might be changed in future releases to honour the
// wxSOCKET_BLOCK flag).
//
// Connect(addr, FALSE) will issue a nonblocking connection request
// and return immediately. If the return value is TRUE, then the
// connection has been already succesfully established. If it is
// FALSE, you must wait for the request to complete, either with
// WaitOnConnect() or by watching wxSOCKET_CONNECTION / LOST
// events (please read the documentation).
//
// WaitOnConnect() itself never blocks the GUI (this might change
// in the future to honour the wxSOCKET_BLOCK flag). This call will
// return TRUE if the connection request completed succesfully, or
// FALSE otherwise, which in turn might mean:
// a) that the specified timeout ellapsed, or
// b) that the connection request failed.
// Use IsConnected() to distinguish between these two.
//
// So, in a brief, you should do one of the following things:
//
// For blocking Connect:
//
// bool success = Connect(addr, TRUE);
//
// For nonblocking Connect:
//
// Connect(addr, FALSE);
// WaitOnConnect(seconds, millis);
// success = IsConnected();
//
// And that's all :-)
