 319   // ---------------------------
 320   //
 321   // There are two ways to use Connect(): blocking and non-blocking,
 322   // depending on the value passed as the 'wait' (2nd) parameter.
 323   //
 324   // Connect(addr, true) will wait until the connection completes,
 325   // returning true on success and false on failure. This call blocks
 326   // the GUI (this might be changed in future releases to honour the
 327   // wxSOCKET_BLOCK flag).
 328   //
 329   // Connect(addr, false) will issue a nonblocking connection request
 330   // and return immediately. If the return value is true, then the
 331   // connection has been already successfully established. If it is
 332   // false, you must wait for the request to complete, either with
 333   // WaitOnConnect() or by watching wxSOCKET_CONNECTION / LOST
 334   // events (please read the documentation).
 335   //
 336   // WaitOnConnect() itself never blocks the GUI (this might change
 337   // in the future to honour the wxSOCKET_BLOCK flag). This call will
 338   // return false on timeout, or true if the connection request
 339   // completes, which in turn might mean:
 340   //
 341   //   a) That the connection was successfully established
 342   //   b) That the connection request failed (for example, because
 343   //      it was refused by the peer.
 344   //
 345   // Use IsConnected() to distinguish between these two.
 346   //
 347   // So, in a brief, you should do one of the following things:
 348   //
 349   // For blocking Connect:
 350   //
 351   //   bool success = client->Connect(addr, true);
 352   //
 353   // For nonblocking Connect:
 354   //
 355   //   client->Connect(addr, false);
 356   //
 357   //   bool waitmore = true;
 358   //   while (! client->WaitOnConnect(seconds, millis) && waitmore )
 359   //   {
 360   //     // possibly give some feedback to the user,
 361   //     // update waitmore if needed.
 362   //   }
 363   //   bool success = client->IsConnected();
 364   //
