Hello :

Is there safe/easy way to downcast shared pointers?

ie boost::shared_ptr< Derived_Type > dPtr = [appropriate_method_here] ( base_ptr );

Thanks in advance; Steve a.

You could downcast reference instead of shared_ptr. Derived_Type& derived_ref = polymorphic_downcast<Derived_Type&>( *base_ptr ); I am not sure it what you want though. Gennadiy
