Yes, "Win32 API function" would be correct, but I followed the existing code...

The only place is CreateFileMapping. Other places (DuplicateHandle and
MapViewOfFileEx) don't log arguments. I guess the original developer thought
that size and name arguments to CreateFileMapping() might be useful for

I saw several Microsoft pages, including a page someone introduced me here, and
they didn't quote the user right. I'm comfortable with the current code, but I
don't mind if the committer adds some quotation.
