Install File System Development

Hi,

I'm trying to make a private IFS in WinCE, and working with Platform
Builder in emulated environment with RamDisk.

I have successfully implemented a null file system and have verified
that the MyFSD.dll was loaded and unloaded.

But after that, I have tried to implement some of the functions that
FSD should provide for FSD Manager. Two of them, MyFSD_MountDisk() and
MyFSD_UnmountDisk were implemented and the .def file was properly
modified for FSDMGR to know that. (below)

EXPORTS
MyFSD_MountDisk
MyFSD_UnmountDisk
FSD_MountDisk=MyFSD_MountDisk
FSD_UnmountDisk=MyFSD_UnmountDisk
MyFSD_...
.......

After the implementation of the above, I was trying to see if the IFS
was properly mounted, but found that the function MyFSD_MountDisk() was
never called. DllMain() was called twice - DLL_PROCESS_ATTACH,
DLL_PROCESS_DETACH. It was unloaded just after it was loaded.

Does anyone can tell me any clue or suggestion? What should I do to
mount a null file system? Do I have to change more of registery
entries?


Thanks in advance.

What do you return in your DLL entry?
Have you added the registry? For example:
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\mydfs]
"Dll"="mydfs.dll"
"Paging"=dword:0

The following is a DEF file from my project, it can work perfectly on
WinCE4.2(5.0 not tested).
LIBRARY MYDFS
EXPORTS
FSD_MountDisk
FSD_UnmountDisk
FSD_Notify
FSD_DeviceIoControl
...

I don't know whether it will be of help.

I have solved the problem. I thought I added the registry entries
correctly, but
found that it was wrong. The name of the dll has some upper and lower
alphabets mixed,
but I used lower-case only on the key and upper/lower mixed one on the
value.

Anyway, thanks Gopise,
