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.
