C++ (Cpp) Promise::future Examples

Example #1

File: servicedirectoryclient.cpp Project: cgestes/libqi

 void ServiceDirectoryClient::onSDEventConnected(qi::Future<SignalLink> future,
   qi::Promise<void> promise, bool isAdd)
 {
   if (promise.future().isFinished()) {
     return;
   }
   if (future.hasError())

     ready = _addSignalLink && _removeSignalLink;
   }
   if (ready)
   {
