NAME¶
SDL_PumpEvents - Pumps the event loop, gathering events from the input devices.
SYNOPSIS¶
#include "SDL.h"
void SDL_PumpEvents(
void);
DESCRIPTION¶
Pumps the event loop, gathering events from the input devices.
SDL_PumpEvents gathers all the pending input information from devices and
places it on the event queue. Without calls to
SDL_PumpEvents no events
would ever be placed on the queue. Often calls the need for
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. your filtering them), then you must call
SDL_PumpEvents to force an event queue update.
Note:
You can only call this function in the thread that set the video mode.
