Also, sleep != Sleep. One is a libc function, the other is a win32 function.

Well then why when I ctrl alt delete does my game crash when I call rest, but when I call sleep it works flawlessly?

You screwed up somewhere? Just look at the source I posted above; if you don't have a callback, rest() calls Sleep() directly.

Doesn't crash after ctrl alt delete

     while(!key[KEY_ESC])
     {
          FpsCounter::NewFrameStarted();
          deltaTime = FpsCounter::GetDeltaTime();

          firstmap.Draw(0, 0, 1);

          Canvas::Refresh();
          
          Sleep(1);
     }

Crashes after ctrl alt delete

     while(!key[KEY_ESC])
     {
          FpsCounter::NewFrameStarted();
          deltaTime = FpsCounter::GetDeltaTime();

          firstmap.Draw(0, 0, 1);

          Canvas::Refresh();
          
          rest(1);
     }

edit:
nm
rest(0); crashes.

I like signatures that only the signer would understand. Inside jokes are always the best, because they exclude everyone else.

You'll need to post your entire project to determine what's wrong. rest(1) under windows ends up calling Sleep(1) after two or three regular function calls.

What version of Allegro are you using? In the Windows version of 4.2.0, there's a bug that causes the program to crash when CTRL+ALT+DEL is pressed. This has been fixed in 4.2.1
