[Boost-users] bind and weak pointers

What is the prefered method of creating a boost::function<void()>, via boost bind, that is calling a member function of a class, and that class instance is held inside the bind object as a weak ptr.

Thus, when the function is called, it will try to lock the shared_ptr, if successful it calls the bound function, otherwise it does nothing.

Is there an standard way of doing this?  Or do I have to write my own custom intermediate function? (which is how I do it now).
