I would like to propose adding const_pointer_cast<> to shared_ptr, in exactly the same way that there is dynamic_pointer_cast<> and static_pointer_cast<>. I am surprised that it is missing. Is there a reason for that? If not, I will submit a patch that implements this. Thanks. -- Colin

Isn't it already there? I see it on line 378 of shared_ptr.hpp in boost 1.31. Bob

Yes, here's the documentation: http://www.boost.org/libs/smart_ptr/shared_ptr.htm#const_pointer_cast Jonathan

I'm terribly sorry. I was looking at 1.30. -- Colin
Hmm, maybe you're looking at detail/shared_ptr_nmt.hpp? (which does not have these templates) My shared_ptr.hpp contains: template<class T, class U> shared_ptr<T> const_pointer_cast(shared_ptr<U> const & r) { return shared_ptr<T>(r, detail::const_cast_tag()); } -t On Aug 4, 2004, at 6:54 PM, Colin Rafferty wrote:
