Event Handling

Introduction
Event handling allows your application to receive input from the user. Event handling is initialized (along with video) with a call to:
SDL_Init(SDL_INIT_VIDEO);
(see Initialization & Shutdown and SDL_Init() for details)
Internally, SDL stores all the events waiting to be handled in an event queue. Using functions like SDL_PollEvent(), SDL_PeepEvents() and SDL_WaitEvent() you can observe and handle waiting input events.
The key to event handling in SDL is the SDL_Event union. The event queue itself is composed of a series of SDL_Event unions, one for each waiting event. SDL_Event unions are read from the queue with the SDL_PollEvent() function and it is then up to the application to process the information stored with them.
