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.
