NAME
SDL_PumpEvents - Pump the event loop, gathering events from the input devices.
SYNOPSIS
#include <SDL3/SDL_events.h>
void SDL_PumpEvents(void);
DESCRIPTION
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.
THREAD SAFETY
This function should only be called on the main thread.
AVAILABILITY
This function is available since SDL 3.2.0.
