What you can do is enumerate all the handles owned by a process and get
the information,
and the prototype for this is on pp 70-71 of Nebbett's book.
Note that the newer DDKs (XP and beyond) cannot be included without
reporting compilation
errors, so I had to hand-edit
#ifdef _NEBBETT
#endif
around the constructs that do not parse properly in C++, and do a #define
_NEBBETT before
doing the #include <ntddk.h>.
Yeah, the new WDK (replacement for DDK) is entirely incompatible. Nebbett's
idea of using a namespace before the #include so that all symbols defined in
the include file are put into the NT:: namespace is a good one, but that is
not sufficient to avoid build errors in modules that also needed to #include
<windows.h>. Out of desperation, I created MyNtDDk.h and copy/pasted the
relevant stuff into it, renaming as necessary to avoid conflicts with
<windows.h>.
BTW, your technique won't work for Notepad, which does not keep the file
that is being edited open. It opens the file, reads the contents into the
Edit control, and closes the file again. So your enumeration won't show the
file being edited. That's why I suggested hooking NtCreateFile to be
notified when Notepad opened the file and catch it in the act.
