Kernel mode programming in VC++

[Arun]

Hello Experts,

I have an asm routine which uses privileged instructions like in, out,
cli, etc., I need to execute this as a Win32 application under VC++.
Since the instructions are privileged, I can't execute the same under User
mode as a normal Win32 application, so I have to execute this routine in
kernel mode.

One solution is to encapsulte the routine as a Device driver for Windows &
call the same from the application, but, I am looking out for a easy
solution. Please help...

Thank you.

Regards,
Arun

The easiest solution will be to ask someone in a newsgroup where they know
what the heck you're talking about! Try one of the newsgroups on the
news.microsoft.com server. Platform-specific questions are off-topic here.

This is off topic in this newsgroup. Here, we discuss the standard c++
language. Anything that is platform specific is off topic. You do
realize that your question is about the windows operating system and
not the C++ language.

Please ask in a more apprpriate newsgroup. This one is for discussing
the C++ language proper, not various platforms that support it. See
this FAQ for what is on-topic here and for a list of other places you
might consider asking:
