/*
* As you know, windows and unix do have a different philosophy with regard to
* the question of how a filesystem should be laid out. While we unix geeks
* learned to love the 'one-tree-rooted-at-/' approach, windows has in fact
* a whole forest of filesystem trees, each of which is typically identified by
* a drive letter.
*
* We would like wine to integrate as smoothly as possible (that is without
* sacrificing win32 compatibility) into the unix environment. For the
* filesystem question, this means we really would like those windows
* applications to work with unix path- and file-names. Unfortunately, this
* seems to be impossible in general. Therefore we have those symbolic links
* in wine's 'dosdevices' directory, which are used to simulate drives
* to keep windows applications happy. And as a consequence, we have those
* drive letters show up now and then in GUI applications running under wine,
* which gets the unix hardcore fans all angry, shouting at us @#!&$%* wine
* hackers that we are seducing the big companies not to port their applications
* to unix.
*
* DOS paths do appear at various places in GUI applications. Sometimes, they
* show up in the title bar of an application's window. They tend to accumulate
* in the most-recently-used section of the file-menu. And I've even seen some
* in a configuration dialog's edit control. In those examples, wine can't do a
* lot about this, since path-names can't be told appart from ordinary strings
* here. That's different in the file dialogs, though.
*
* With the introduction of the 'shell' in win32, Microsoft established an
* abstraction layer on top of the filesystem, called the shell namespace (I was
* told that Gnome's virtual filesystem is conceptually similar). In the shell
* namespace, one doesn't use ascii- or unicode-strings to uniquely identify
* objects. Instead Microsoft introduced item-identifier-lists (The c type is
* called ITEMIDLIST) as an abstraction of path-names. As you probably would
* have guessed, an item-identifier-list is a list of item-identifiers (whose
* c type's funny name is SHITEMID), which are opaque binary objects. This means
* that no application (apart from Microsoft Office) should make any assumptions
* on the internal structure of these SHITEMIDs.
*
* Since the user prefers to be presented the good-old DOS file-names instead of
* binary ITEMIDLISTs, a translation method between string-based file-names and
* ITEMIDLISTs was established. At the core of this are the COM-Interface
* IShellFolder and especially it's methods ParseDisplayName and
* GetDisplayNameOf. Basically, you give a DOS-path (let's say C:\windows) to
* ParseDisplayName and get a SHITEMID similar to <Desktop|My Computer|C:|windows|>.
* Since it's opaque, you can't see the 'C', the 'windows' and the other stuff.
* You can only figure out that the ITEMIDLIST is composed of four SHITEMIDS.
* The file dialog applies IShellFolder's BindToObject method to bind to each of
* those four objects (Desktop, My Computer, C: and windows. All of them have to
* implement the IShellFolder interface.) and asks them how they would like to be
* displayed (basically their icon and the string displayed). If the file dialog
* asks <Desktop|My Computer|C:|windows> which sub-objects it contains (via
* EnumObjects) it gets a list of opaque SHITEMIDs, which can be concatenated to
* <Desktop|...|windows> to build a new ITEMIDLIST and browse, for instance,
* into <system32>. This means the file dialog browses the shell namespace by
* identifying objects via ITEMIDLISTs. Once the user has selected a location to
* save his valuable file, the file dialog calls IShellFolder's GetDisplayNameOf
* method to translate the ITEMIDLIST back to a DOS filename.
*
* It seems that one intention of the shell namespace concept was to make it
* possible to have objects in the namespace, which don't have any counterpart
* in the filesystem. The 'My Computer' shell folder object is one instance
* which comes to mind (Go try to save a file into 'My Computer' on windows.)
* So, to make matters a little more complex, before the file dialog asks a
* shell namespace object for it's DOS path, it asks if it actually has one.
* This is done via the IShellFolder::GetAttributesOf method, which sets the
* SFGAO_FILESYSTEM if - and only if - it has.
*
* The two things, described in the previous two paragraphs, are what unixfs is
* based on. So basically, if UnixDosFolder's ParseDisplayName method is called
* with a 'c:\windows' path-name, it doesn't return an
* <Desktop|My Computer|C:|windows|> ITEMIDLIST. Instead, it uses
* shell32's wine_get_unix_path_name and the _posix_ (which means not the win32)
* fileio api's to figure out that c: is mapped to - let's say -
* /home/mjung/.wine/drive_c and then constructs a
* <Desktop|/|home|mjung|.wine|drive_c> ITEMIDLIST. Which is what the file
* dialog uses to display the folder and file objects, which is why you see a
* unix path. When the user has found a nice place for his file and hits the
* save button, the ITEMIDLIST of the selected folder object is passed to
* GetDisplayNameOf, which returns a _DOS_ path name
* (like H:\home_of_my_new_file out of <|Desktop|/|home|mjung|home_of_my_new_file|>).
* Unixfs basically mounts your dos devices together in order to construct
* a copy of your unix filesystem structure.
*
* But what if none of the symbolic links in 'dosdevices' points to '/', you
* might ask ("And I don't want wine have access to my complete hard drive, you
* *%&1#!"). No problem, as I stated above, unixfs uses the _posix_ apis to
* construct the ITEMIDLISTs. Folders, which aren't accessible via a drive letter,
* don't have the SFGAO_FILESYSTEM flag set. So the file dialogs should'nt allow
* the user to select such a folder for file storage (And if it does anyhow, it
* will not be able to return a valid path, since there is none). Think of those
* folders as a hierarchy of 'My Computer'-like folders, which happen to be a
* shadow of your unix filesystem tree. And since all of this stuff doesn't
* change anything at all in wine's fileio api's, windows applications will have
* no more access rights as they had before.
*
* To sum it all up, you can still savely run wine with you root account (Just
* kidding, don't do it.)
*
* If you are now standing in front of your computer, shouting hotly
* "I am not convinced, Mr. Rumsfeld^H^H^H^H^H^H^H^H^H^H^H^H", fire up regedit
* and delete HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
* Explorer\Desktop\Namespace\{9D20AAE8-0625-44B0-9CA7-71889C2254D9} and you
* will be back in the pre-unixfs days.
