Is there a C++/CLI smart pointer project (e.g. scoped_ptr)?

Question

Is there a C++/CLI RAII smart pointer class for containment of a native pointer in a managed type? Just wondering, before I go write my own clr_scoped_ptr value class template.

I'm aware of the Microsoft-provided:

• containment of a managed handle in a native class: auto_gcroot

• containment of a managed handle in a managed class: auto_handle

The above two are similar to auto_ptr or unique_ptr.

• I gave skeleton code for a counted_handle here, similar to shared_ptr

But all these are for disposing managed ref class instances, not for freeing native objects.

Answer 1

This one looks fairly complete, but I'm not looking for silent transfer of ownership ala auto_ptr.
