All error HRESULTs are returned via exceptions.  Unfortunately, there isn't
a reliable way to get a success HRESULT - when it is known to be
significant, functions often return them, and it sounds like we could also
do that in your case (assuming it *always* returns None now).  It should
also be possible to stick all HRESULTs in some thread-local-storage and
fetchable via "GetLastHRESULT()" or similar.  What codes are you expecting
to see?
