Why?  What do you think `stat' in MSVCRT does?  (You can find the
sources on the Internet.)  It calls some of the same Win32 APIs, and
then fills `struct stat'.  There''s nothing magic about that, and
nothing to be afraid of.

You can't.  To get the missing information you must go to lower-level
APIs.
