Functions

SDL_AddEventWatch⚠	Add a function which is called when an event is added to the queue.
SDL_DelEventWatch⚠	Remove an event watch function added with SDL_AddEventWatch
SDL_EventState⚠	This function allows you to set the state of processing certain events.
SDL_FilterEvents⚠	Run the filter function on the current event queue, removing any events for which the filter returns 0.
SDL_FlushEvent⚠	This function clears events of a particular type from the event queue.
SDL_FlushEvents⚠	This function clears a range of event types from the event queue.
SDL_GetEventFilter⚠	Return the current event filter - can be used to "chain" filters.
SDL_GetEventState⚠	As SDL_EventState, but provides the "query" part for you.
SDL_HasEvent⚠	Checks to see if certain event types are in the event queue.
SDL_HasEvents⚠	Checks to see if a range of event types are in the event queue.
SDL_PeepEvents⚠	Checks the event queue for messages and optionally returns them.
SDL_PollEvent⚠	Polls for currently pending events.
SDL_PumpEvents⚠	Pumps the event loop, gathering events from the input devices.
