SDL_FlushEvents

Clear events of a range of types from the event queue.

Syntax

void SDL_FlushEvents(Uint32 minType, Uint32 maxType);

Function Parameters

minType

the low end of event type to be cleared, inclusive; see SDL_EventType for details

maxType

the high end of event type to be cleared, inclusive; see SDL_EventType for details

Remarks

This will unconditionally remove any events from the queue that are in the range of minType to maxType, inclusive. If you need to remove a single event type, use SDL_FlushEvent() 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.

Version

This function is available since SDL 2.0.0.
