I was wondering why shared_ptr/array include both a ptr to the control block and a ptr to the data (ptr) in the class itself. I assume it's for performance reasons, but I didn't find anything about that in the docs.
It's for aliasing. You can have a shared_ptr that points to a subobject of the object controlled by the control block.
Ah, of course. Does that apply to shared_array too? Olaf
