- Pumps
- the event loop, gathering events from the input devices. <p>
- <b>SDL_PumpEvents</b>
- gathers all the pending input information from devices and places it on
- the event queue. Without calls to <b>SDL_PumpEvents</b> no events would ever be
- placed on the queue. Often calls the need for <b>SDL_PumpEvents</b> is hidden from
- the user since <i><b>SDL_PollEvent</b></i> and <i><b>SDL_WaitEvent</b></i> implicitly call <b>SDL_PumpEvents</b>.
- However, if you are not polling or waiting for events (e.g. your filtering
- them), then you must call <b>SDL_PumpEvents</b> to force an event queue update.

- <blockquote><b>Note: <p>
- You can only call this function in the thread that set the video
- mode. </blockquote>
