[SDL] How safe is not freeing a surface all the time?

[Manuel García Cabrera]

I used to loop this:

image = SDL_CreateRGBSurfaceFrom( ... );
SDL_BlitSurface(image, &rect, screen, NULL);
SDL_UpdateRect(screen,0,0,0,0);
SDL_FreeSurface(image);




I want to know if looping this is safe:

image = SDL_CreateRGBSurfaceFrom( ... );
SDL_BlitSurface(image, &rect, screen, NULL);
SDL_UpdateRect(screen,0,0,0,0);


And then calling at the end of my app a single:

SDL_FreeSurface(image);
