sdlFilterEvents function events

void sdlFilterEvents(
  1. Pointer<NativeFunction<SdlEventFilter>> filter,
  2. Pointer<NativeType> userdata
)

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

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.

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

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.2.0.
