[boost-users][function] how to
Hello, function<void(Base *)> funcB; function <void(Derived *)> funcD; Is it possible to convert somehow funcD --> funcB ? Thanks.
funcB = boost::lambda::bind(funcD, ll_static_cast<Derived*>(_1));
Great, thank you!
The only problem is that my actual code uses shared_ptr<Base>, shared_ptr<Derived>, rather than plain ptrs, so the ll_static_cast doens't compile... Is it still possible to enhance the formula? :)

I don't think that there is a predefined way to do this, so you would need to create your own wrapper function object using boost::static_pointer_cast instead of static_cast. In Christ, Steven Watanabe
