[Bug 44685] New: GetVolumePathNameW Path Bug

https://bugs.winehq.org/show_bug.cgi?id=44685

Bug ID: 44685
           Summary: GetVolumePathNameW Path Bug
           Product: Wine
           Version: 3.3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]
          Reporter: [e-mail]

volumenameW contains a path with unix / characters but the GetVolumePathNameW
loop routine uses a strrchrW function looking for backslash's in volumenameW
and the returned volumename is then incorrect.

changing

c = strrchrW( volumenameW, '\' );

to

c = strrchrW( volumenameW, '/' );

results in correct volumename being returned.

Affects any windows app using GetVolumePathNameW and is mentioned in bug
reports

--- Comment #1 from Stan  ---
Multiple windows apps are getting the wrong volume info and it might lead to
strange behaviours with those apps.

The bug was only brought out by Native Instruments "Native Access" halting on
the bug whereas other apps probably just proceed with the wrong volume info
which might affect other functions down the line in those apps.

The printout of GetVolumePathNameW volumenameW is a path with forward slashes
ie

"C:/home/user/.wine/drive_c/Program Files/App/App.exe"

then the loop code traverses that path starting at the end and moving toward
the start but the loop code is searching for backslash's in volumenameW which
don't exist and the loop breaks after one iteration and the return volume path
is the original path with slash's converted to double backslashes with an extra
backslash on the end which is useless for GetVolumeInformationW which flags an
error.

GetVolumePathNameW returns

"C:\home\user\.wine\drive_c\Program Files\App\App.exe\"

whereas it should return

There's no reason to file a separate bug; the cause is already identified and
described in bug 42446. If bug 43240 is indeed the same bug then it should also
be marked a duplicate.
