A problem on STATUS_REPARSE

NTFSD
1

Hi,
I’m using STATUS_REPARSE to redirect original file c:\temp1\a.doc to
c:\temp2\b.doc.
In IRP_MJ_CREATE, I replace Irp->FileObject->FileName with new file
name buffer and free the original filename buffer. After that I
complete the IRP as follow:

Irp->IoStatus.Information = IO_REPARSE;
Irp->IoStatus.Status = STATUS_REPARSE;
IoCompleteRequest(Irp, IO_NO_INCREMENT);
return STATUS_REPARSE;

The problem is after this IRP is returned to IO manager, I do not see
IO manager send new IRP with the new file name to FS driver as I expected.
The document opened is still original one: c:\temp1\a.doc not
c:\temp2\b.doc.

I can not figure our what wrong is. Do I miss something before I return
STATUS_REPARSE?

Thank you for your help

It works. Thanks Max.
I still have one problem on document saving. During document saving,
I can see two rename steps. One is from doc file to tmp file. Other is
from a new tmp file to doc file. But after those two renames, MS Word
give an error message “Word can not complete the saving due to a file
permission error”. Where is the problme?

Thanks again for your help.

Try

??\c:\temp2\b.doc
