This is a very powerful and flexible feature. The filter is prototyped as:
typedef int (*SDL_EventFilter)(const SDL_Event *event);
There is one caveat when dealing with the SDL_QUITEVENT event type. The event filter is only called when the window manager desires to close the application window. If the event filter returns 1, then the window will be closed, otherwise the window will remain open if possible. If the quit event is generated by an interrupt signal, it will bypass the internal queue and be delivered to the application at the next event poll.
