Passing a boost::shared_ptr as a parameter by const reference is a *very* good idea -- if you don't do this then you're needlessly copying it, and copies are expensive (requires multiple interlocked operations). It only becomes a potential concern in a multithreaded environment, and even then only if you're mixing read/write operations on the same instance across multiple threads (eg. from a member field). But that's not special to shared_ptr, most data structures will require additional locks if you're doing that sort of thing. And providing proper "get" methods that return the shared_ptr by value (from within the appropriate lock) will mitigate much of those sorts of problems too. _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
