C++ riddle

This time small C++ riddle which took me some time to figure out :) Background: My editor currently use sockets connection to pass data between Qt UI and "Editor module" in engine. Inside editor module this happen on two threads: Processing events on editor module side Receive data and send result of events back to UI.  Code of two main function execute on them can found bellow: Processing events (Show/hide) EError CAppEditor::processEditorEvents( void ) { if (!m_eventsToProcess) { return EErrors::Succeeded_NothingToDo; } SEvent * events = wrAtomic::exchange(&m_eventsToProcess, (SEvent*)nullptr); if (events != nullptr && events->next != nullptr) { SEvent * rEvents = nullptr; while(events != nullptr) { SEvent* tmp = events; events = events->next; tmp->next = rEvents; rEvents = tmp; } events = rEvents; } while(e

With time passing by all previous years slowly starting blending together but well I'm already at this age where this is pardonable. On one of C++ courses we got exercise to do program of our choice to show that we learned language. I decided that isometric game in SDL software mode will be great idea. And so I started working on it. What a great joy I had when everything finally started working together and I was able to send it to person conducting classes. I got passing marks and this was end of story.  Well at least for a lot of project this would be truth but in this cases there is a lot more. Some time passed and with friend we decided to make casual game. Code from course project was really useful but software rendering were too slow so I switched whole stuff on OpenGL and some time later we finished  "Pirate Cr
