Re: [Boost-users] COM and boost::intrusive_ptr

CComPtr-like usage: boost::intrusive_ptr<IVideo> video; someObject->QueryInterface(IID_IVideo,(void**)&video);

Is there a better way? How do you bring intrusive_ptr and QueryInterface together?

[Nat] Sorry if this is naïve...

Wouldn't it work to do something like this?

IVideo* temp_video = NULL; someObject->QueryInterface(IID_IVideo, &temp_video); boost::intrusive_ptr<IVideo> video(temp_video);

As the construction of the intrusive_ptr increases the ref count you have

to call temp_video->Release(); afterwards. Anyway, in my opinion this obvious solution is too error-prone.
