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.
