freeing an SDL_Surface correctly?

Can i free my SDL_Surface* surf by doing this:

    SDL_Surface* surf;
    for(int i = 0; i < 5; i++){
         surf = TTF_RenderText_Blended(foofont, foostring, foocolor);
    }
    SDL_FreeSurface(surf);
    surf = NULL;

Or does this cause memory leaks?

Edited: Based on how I understand the documentation, that will cause a leak. Seeing as you are basically calling the function 5 times, where it creates a new surface each time. Ie, you need to free all the surfaces each time. so

for(int i = 0; i < 5; i++)
{
    surf = TTF_RenderText_Blended(foofont, foostring, foocolor);
    SDL_FreSurface(surf)
}
surf = NULL;

You can read the documentation here:
