How to adjust refCount?

I am following (and understanding) the Apple documentation on
implementing -copyWithZone and -mutableCopyWIthZone.
My code needs to adjust refCount to 1 since the copy of the object
made by the superclass's -copyWithZone was a shallow copy. But how do
I do that? There seems to be no instance variable or method I can use
called refCount that I can assign 1 to. Do I need to #import anything
extra?
I see that NSObject has retainCount, but the Apple docs (Memory
management -> Implementing Object Copy -> Figure [1 Initialization of
the reference count during a copy] and nearby text) explicitly refer
to refCount. Is this a documentation error?
