SDL_GetKeyState - Get a snapshot of the current keyboard state

       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.

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