"Connecting" SDL_Surface to shared_ptr

I would like to know how can I connect SDL_Surface * with shared_ptr?
I need to call SDL_FreeSurface(SDL_Surface*) before I remove SDL_Surface . How can I "change the delete process" in shared_ptr?

Just pass SDL_FreeSurface to the constructor:

 std::shared_ptr<SDL_Surface> shared_surf(SDL_LoadBMP("foo.bmp"), SDL_FreeSurface);

Just make sure you don't do this with the pointer returned by SDL_SetVideoMode or SDL_GetVideoSurface .
