SDL_FilterEvents

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

Syntax

                      void *userdata);

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.
