NAME
       SDL_PollEvent - Polls for currently pending events.

SYNOPSIS
       #include "SDL.h"

       int SDL_PollEvent(SDL_Event *event);

DESCRIPTION
       Polls  for  currently  pending  events,  and returns 1 if there are any
       pending events, or 0 if there are none available.

       If event is not NULL, the next event is  removed  from  the  queue  and
       stored in that area.

EXAMPLES
       SDL_Event event; /* Event structure */

       .
       .
       .
       /* Check for events */
       while(SDL_PollEvent(&event)){  /* Loop until there are no events left on the queue */
         switch(event.type){  /* Process the appropiate event type */
           case SDL_KEYDOWN:  /* Handle a KEYDOWN event */
             printf("Oh! Key press
       ");
             break;
           case SDL_MOUSEMOTION:
             .
             .
             .
           default: /* Report an unhandled event */
             printf("I don't know what this event is!
       ");
         }
