SDL API Reference                               SDL_PumpEvents(3)



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  dev-
     ices.

     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  impli-
     citly  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.
