If you pass the variable by reference then the called routine gets a poitner to the variable (which is a poitner to the object) so the called routine can only manipulate the location of the pointer and not the object directly.

Ahhh, pointer to pointers. Arrays of pointers to pointers. Pointers to arrays of pointers to pointers.

Now I remember why I used to get those C headaches.
