Pump the event loop, gathering events from the input devices.
This function updates the event queue and internal input device state.
SDL_PumpEvents() gathers all the pending input information from devices and
places it in the event queue. Without calls to SDL_PumpEvents() no events
would ever be placed on the queue. Often the need for calls to
SDL_PumpEvents() is hidden from the user since SDL_PollEvent() and
SDL_WaitEvent() implicitly call SDL_PumpEvents(). However, if you are not
polling or waiting for events (e.g. you are filtering them), then you must
call SDL_PumpEvents() to force an event queue update.
\threadsafety This function should only be called on the main thread.
\since This function is available since SDL 3.2.0.
