Converting to Dos Name ?

NTFSD
1

Hello,

After calling the FltGetFileNameInformation() in the
pre-create callback routine , i got the full path name - like

Ex: \Device\HarddiskVolume1\Documents and Settings\Test Results.txt

How can i convert the \Device\HarddiskVolume1 to dos name as
“C:\Documents and Settings\Test Results.txt” ? ( Any direct function
?)

I tired the following

  1. FltGetDiskDeviceObject(FltObjects->Volume,&DiskDeviceObject)

  2. IoVolumeDeviceToDosName(DiskDeviceObject,&DosName)

  3. Finally i append the file object into the DosName & got the result as
    ( DosName + FileObject )
    C:\Documents and Settings\Test Results.txt

Can anyone tell me other smart way for doing this ?

Thanks,
SivaRaja
