I'm not sure I follow here. (This is all quite of new to me)
Are you telling me that I should add WINAPI after HRESULT?

Will fix.

I wanted to propagate the return value from the called function, but perhaps 
I should just refactor a bit and do the logging in there instead.

at other places in the same file.

Well, they are used for different things. But sure, I'll try to avoid it and 
thus make it a bit clearer.
