Should I use ATLs smart pointers CComPtr or the native _com_ptr_ type?

The primary difference is that _com_ptr_ supports exception handling and CComPtr does not. Also, the comments above mentioned, if you want to use ATL on non-Visual C++ platforms, you should stick with CComPtr because _com_ptr_ is only provided as part of Microsoft’s C++ implementation.
