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

Defined in SDL3/SDL_events.h

#include "SDL3/SDL.h"
void SDL_FlushEvents(Uint32 minType, Uint32 maxType);

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.

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

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
