Dear all, I was playing with Boost.Signals and stumbles across a problem which required something like the equivalent of a shared_connenction, i.e. the last reference to it will finally disconnent. This can of course be simulated with a boost::shared_ptr<scoped_connection>, but native support for it is always preferable. The use is that some change manager returns a connection which goes through several application layers. The time the connection finally arives at destination, it has felt multiple ctor's and dtors: View::View(Doc* p) : m_con(p->Register(&OnUpdate) { } shared_connection Doc::Register(void (View::* pmf)(), View* p) { return m_pCm->Register(pmf, p) } etc.. Or did I not read the documentation properly? Wkr, me
