And this was correct.  If you wanted to store the pointer
address, as you write, then you would indeed have to use &
to obtain it (leaving aside what would that be good for).

The point is that you do *not* want to store the address of
the pointer (i.e. a pointer to the pointer), but the pointer
itself.

Now, if that's clear and you only didn't express yourself
very clearly, I'm sorry for nitpicking.  However if it
confused you, you still don't understand (but I cannot
explain it better).
