Hmm. Do you really need access to the deleter, or only information about the deleter type used? Or do you actually need an answer to the question "did I create this shared_ptr?" BTW, introspection isn't currently part of shared_ptr because whenever I encounter a need for yet another shared_ptr feature, I always try _very hard_ to solve the problem using only the existing public interface. This unofficial filter has always worked well so far. :-) (And when I failed to apply it - shared_from_this - it was a mistake.) Have you considered keeping a std::set< weak_ptr<> > to track shared_ptr instances created by boost.python? (Shot in the dark, don't yell at me if I missed the point.) _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
