(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_FilterEvents

Run a specific filter function on the current event queue, removing any events for which the filter returns 0.

Function Parameters

filter	the SDL_EventFilter function to call when an event happens
userdata	a pointer that is passed to `filter`

Remarks

See SDL_SetEventFilter() for more information. Unlike SDL_SetEventFilter(), this function does not change the filter permanently, it only uses the supplied filter until this function returns.
