NAME
     SDL_GetKeyState - Get a snapshot  of  the  current  keyboard
     state

SYNOPSIS
     #include "SDL.h"

     Uint8 *SDL_GetKeyState(int *numkeys);

DESCRIPTION
     Gets a snapshot of the current keyboard state.  The  current
     state  is  return as a pointer to an array, the size of this
     array is stored in numkeys. The  array  is  indexed  by  the
     SDLK_*  symbols. A value of 1 means the key is pressed and a
     value of 0 means its not. The pointer returned is a  pointer
     to  an  internal  SDL  array  and should not be freed by the
     caller.

          Note:

          Use SDL_PumpEvents to update the state array.

EXAMPLE
     Uint8 *keystate = SDL_GetKeyState(NULL);
     if ( keystate[SDLK_RETURN] ) printf("Return Key Pressed.
     ");
