Hello All,
I am writing filesystem filter driver for Windows 2K/XP enviorment. In Pre - IRP_MJ_CREATE, in case of relative opens, I am trying to do query IRP_MJ_QUERY_INFORMATION with FileNameInformation but i get error 0xC0000008 which is invalid parameter. Is it not right way to get absolute file name in terms of relative file open??
Thanks
Ashish
Do you query name for RelatedFileObject?
Alexei.

0xC0000008 = STATUS_INVALID_HANDLE
0xC000000D = STATUS_INVALID_PARAMETER
Which is it?
Is the error from FltGetFileNameInformation or from FltCreateFile or from
FltQueryInformationFile?
Assuming you are calling FltGetFileNameInformation to get
FileNameInformation, look at the documented reasons you might get
STATUS_INVALID_PARAMETER.
In general, FltGetFileNameInformation works fine with relative opens, but
there are cases when the filename cannot be obtained. You must recognize
and handle those cases.
It might help if you showed us the call(s).

Or if this isn’t a minifilter (duh!) and you’re calling
ZwQueryInformationFile and the error really is 0xC0000008, check the handle
you’re passing.
