Clean up dynamically allocated memory for an event.
void SDL_CleanupEvent(SDL_Event *event);
|a pointer to the event that should be cleaned up
Some events have dynamically allocated data that must be cleaned up when the event is processed. If you handle any of these events, you should call SDL_CleanupEvent() after processing them: SDL_EVENT_DROP_FILE SDL_EVENT_DROP_TEXT SDL_EVENT_SYSWM SDL_EVENT_TEXT_EDITING
It is safe, but not necessary, to call this function for other event types.
This function is available since SDL 3.0.0.
