NAME
SDL_PumpEvents - Pump the event loop, gathering events from the input devices.
HEADER FILE
Defined in SDL3/SDL_events.h
SYNOPSIS
#include "SDL3/SDL.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.
