(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)


Clear events of a specific type from the event queue.


void SDL_FlushEvent(Uint32 type);

Function Parameters

type the type of event to be cleared; see SDL_EventType for details


This will unconditionally remove any events from the queue that match type. If you need to remove a range of event types, use SDL_FlushEvents() instead.

It's also normal to just ignore events you don't care about in your event loop without calling this function.

This function only affects currently queued events. If you want to make sure that all pending OS events are flushed, you can call SDL_PumpEvents() on the main thread immediately before the flush call.


This function is available since SDL 2.0.0.
