Pointer confusion

Hi, I have a class "A" in which I want to have a reference/ pointer to an object of class "B" for usage within the member functions of A. Currently I do this: // class A definition const Crealysm_d3drenderer::CD3dscene* mD3dscene; // Initial - creation of the renderqueue bool Create(const Crealysm_d3drenderer::CD3dscene *pD3dscene, const int pLightingEffectId); // class A implementation bool CRenderQueue::Create(const Crealysm_d3drenderer::CD3dscene *pD3dscene, const int pLightingEffectId) { if(!pD3dscene->IsLoaded()) return false; if((mD3dscene = pD3dscene) == NULL) return false; // set const pointer to d3dscene Functionally this all works, but I believe I've only made the pointer const, so the actual pointer is const instead of the object it points to. Although I'm not sure, because I'm not able to make changes to the objects it points to (pD3dscene). Can someone clear this up for me?

Thanks, I fully agree. In my case I always try to be cost correct/ on the clear and safe side. 80/20 that is, it should become a goal on its own. For example: bool CRenderable::SetVisible(const bool pVisible) is an example of what my standard approach is.
