Ravi,

I don’t know about Kevin, but it is that way in my version of winioctl.h as well - the one shipped with VS 6.0. Haven’t checked VS.NET yet…

Where did you get the winioctl.h from? I am looking at Win2K RTM sources and it’s defined right
(FILE_SPECIAL_ACCESS)

Below are the FSCTL codes for reparse points from both ntifs.h and

FILE_WRITE_DATA.) Sending a DeviceIoControl with FSCTL_SET_REPARSE_POINT
from user mode was failing and not hitting my filter driver in kernel mode.
After some ugly debugging, I came to find out that Microsoft didn’t define
the ctl codes the same in their headers. Thanks MS!

For serious work, you shouldn’t use the h files and libraries that come
with Developer Studio. The same files are in the Platform SDK, and they
are much more current.

I could be wrong, but I believe Developer Studio 6 shipped quite some
time before Windows 2000.

My point exactly. Thanks Dan. The IOCTL’s definition was changed before Win 2K RTM, after VC6 ship.
Tony points out that developers are not aware of what you say below though. I’ll follow up to make sure
this is properly conveyed.

With the WinXP and forward kits, we have attempted to include *all* the
needed files in the DDK/IFSK to avoid exactly this problem. Note the WinXP
and forward kits also include a full Win2K build environment set. There was
a problem with the WinXP RTM IFS Kit Win2K Build Environment, which has be
fixed since. (See other postings on this list)

If you are missing a headers from current kits - including downlevel build
environments in current kits - this is considered a bug.

Please file it with either the Windows Beta (if you have access) or OSR’s
bug reporting (if you don’t), and we’ll get the files added.

Actively trying to fix this one,
Jean
