NAME
       SDL_UpdateRect - Makes sure the given area is updated on the given screen.


SYNOPSIS
       #include "SDL.h"

       void SDL_UpdateRect(SDL_Surface *screen, Sint32 x, Sint32 y, Sint32 w, Sint32 h);


DESCRIPTION
       Makes  sure  the  given  area  is  updated on the given screen. The rectangle must be confined within the
       screen boundaries (no clipping is done).

       If 'x', 'y', 'w' and 'h' are all 0, SDL_UpdateRect will update the entire screen.

       This function should not be called while 'screen' is locked.
