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.
