…Hi All
I have doubt regarding ntifs.h header file. I have a 2003 server
IFS kit , but I’m finding difference between two header files i.e
“ntifs.h”, what I found was in one ntifs.h (downloaded from web) the
FILE_INFORMATION_CLASS value is different from another (IFS kit). For
example in one file the value of FileObjectIdInformation is 29, and in
another one it is 35. which is correct???..
Please advise…
Regards
K.Raju
Different values for FILE_INFORMATION_CLASSIf the version from the web you
are refering to is from Bo Branten’s site, also known as gnu IFS, it
contains more errors than you can imagine. Trust the 2003 IFS kit from
Microsoft.

Hi Don
Thank you for your reply…
But I did some experiments with filemon tool and Dbgprint in my FSD.
For one of the the IRP_MJ_QUERY_INFORMATION request FileMon prints it as
“FileObjectIdInformation”
And the DbgPrint prints the FileInformationclass value as 35.
If you look at IFS kit ntifs.h the value of
FileObjectIdInformation = 29
where as the downloaded web ntifs.h the value of
FileObjectIdInformation = 35.
this is the same incase of FileStreamInformation. I have checked
only for these two.
Reply with your comments plz.
Regards
K.Raju

I don’t know why this differs, but if you check the ntddk.h from NT DDK you will
find the FileObjectIDInformation is 35 as well.
Same in XP IFS Kit.

I did some quick checks through our archives and it looks to me like
this value changed between NT4 and W2K.
In NT4 it looks like it is 35 and in W2K and later it looks like it is
29.

Hi Neal
Thank you for your info. But, I’m developing my FSD in such a

So which one should I consider for FileObjectIdInformation, 35 or 29 ?.
Please help.

Given that you will most probably need different binaries between these
versions, you should probably use whatever version for which you are
linking/building.
If you DO manage to get a single binary, then you’ll need to base the
correct value upon the version on which you are running. This isn’t any
different than it would be for any other multi-version product.
Of course, I have to wonder why you’d worry so much about supporting an
8 year old OS release.

Is FileObjectIdInformation actually supported in NT4?
I believe that it is supported starting from W2K when assignment of ObjectId
to a file was introduced. If this is the case then this change doesn’t affect
anything.

2-3 year old is the issue. This value HAS changed between XP IFS Kit and 2003
DDK.
Besides, many have to support Windows 95 still. A large customer base still has
it. I will not implement any new features for 9x/Me, but if any bugs arise they must
be dealt with. NT I still want to support. First because there is almost nothing that
differs between NT and 2K/XP/2K3 for my requirements and second… it’s still in
use.
Regards, Dejan.

The IRP_MJ_POWER has changed between NT and 2K. But that was even expected, due
to new PM stuff in 2K. One wouldn’t expect a file information class to differ between
XP and 2K3 though. What days?
It’s last year or the year before 
If someone checks for sure, let us know.
