[Boost-users] downcasting shared pointer

Hi, I was wondering what the recommended way was to downcast shared pointers. I have a a base class, Base, and a derived class Derived. I have a Base shared pointer which points to a Derived object. shared_ptr<Base> d; As part of a unit test, I'm trying to extract the Derived object from it. *static_cast(d.get()); Here I'm extracting the raw pointer, downcasting it to Derived, and then taking the value. It would be nice if there was some method to downcast the shared_ptr itself. Thanks in advance. Please CC me on any reply. Faheem.
