            Bug ID: 39552
           Summary: CreateDirectoryA's behavior with long path whose size
                    max than MAX_PATH-12(248) differs from Windows.
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: wine-bugs(a)winehq.org

On Windows, CreateDirectoryA fail when the path's size longer than
MAX_PATH-12(248) while Wine's implementation success.
According to MSDN[1], there is a default string size limit for paths of 248
characters. This limit is related to how the CreateDirectory function parses
paths.

Is this a purely theoretical problem or is there some app that's actually
affected by this?

Nope. Maybe it is just a purely theoretical problem. I didn't find an
application that depends on this implementation details.
I found this detail because of the implementation of tr2::sys::Open_dir[1].
I think if it is impossible to create a directory whose size max than 248, the
patch can be improved.
