[Boost-users] [shared_from_this] why doesn't _internal_weak_this need to be initialized?

Frank, when I call user_count() on the _internal_weak_ptr before calling share_from_this() I get back 1.  So are you referring to the first shared_ptr constructor in main() (vs the constructor in share_from_this())?  If so how is it initialized?  The shared_ptr constructor gets passed a reference to the object being pointed, are you saying it goes and searches out for _internal_weak_ptr within that object and initializes it if it finds it?

thanks
