Header File

SDL_bool SDL_GetEventFilter(SDL_EventFilter * filter,
                            void **userdata);

SDL_EventFilter *	filter	the current callback function will be stored here.
void **	userdata	the pointer that is passed to the current event filter will be stored here.

(SDL_bool) Returns SDL_TRUE on success or SDL_FALSE if there is no event filter set.

This function can be used to "chain" filters, by saving the existing filter before replacing it with a function that will call that saved filter.

This function is available since SDL 2.0.0.
