When I write a implementation for IStream, what IID's should I support.

Eg. IID_IUnknown etc.

Thank you.

You need to always support IID_IUnknown, and you need to support the IID of
every interface you actually implement/return.  In this case, you are
implementing IStream, so you need to support IID_IStream.
