Confusing SHGetFolderPath

[nog]

Hi,

While I was looking through some of the wine dlls' code I found that the
function SHGetFolderPath is in the shell32 dll and the shfolder dll. Is
this ment to be like this? Because the docs that I read says that the
function is meant to be in shfolder.  Anyway are the two functions meant
to do the same thing? If so then why is the one in shell32 implemented
and working and the one on shfolder doesn't eaven appear to give a fixme
message?

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/she...

tells that ShGetFolderPath is in shell32.lib. So we implemented it there,
and we have a Forward to shell32 in shfolder.dll

Just another datapoint: according to my files SHGetFolderPath does
not exist in Win95, is implemented in shfolder on Win98, and has entry
points in both shfolder and shell32 in Win2000 and WinMe.
   That's probaby why we have the situation described by Uwe Bones in
Wine.

The MSDN tells you:
-----------
Remarks
This function is a superset of {HYPERLINK "SHGetSpecialFolderPath.htm"}SHGetSpecialFolderPath, included with earlier versions of the Shell.
It is implemented in a redistributable DLL, SHFolder.dll, that also simulates many of the new Shell
folders on older platforms such as Windows 95, Windows 98, and Windows NT 4.0. This DLL 
always calls the current platform's version of this function. If that fails, it will try to simulate the 
appropriate behavior.
--------
So the shfolder.dll is only for updating older operating systems. WinME/W2K has this function in shell32.
The shfolder one has a smaller set of supported CSIDL's. I suspect (by looking on the imports with depends)
the shfolder.dll just loads shell32 with LoadLibrary and forwards the functions if a GetProcAddress() is 
successful.
