Hi All,
I am interested in finding out how to install software interrupts that can
be called from user mode. I have looked at the documentation and it seems
that the only functions that are used for setting up interrupt service
routines are those that are used for hardware devices. Such as
IoConnectInterrupt. I am trying to learn how one could hook interrupts and
set others up. Is there any good resources on doing this?
Thanks for your help,
Paul Beaulieu

For what? Are IOCTL calls bad?

Hi,
Mainly for the purpose of knowing how to do it. To see if it is possible
and could be used just like the Native Windows API uses them to call kernel
code.
Thanks,
Paul Beaulieu

maybe to avoid the overhead of the I/O manager, maybe just for curiosity.
There’s a good discussion about this in the book “Undocumented Windows NT”,
which is freely available online, at http://www.windowsitlibrary.com/
This is one of those don’t go there, but if you must questions. Not
exactly the answer to the question, but you might look at

Good discution about interrupts there ? maybe … But I dont think so 
.
Those guys really missinterpret a lot about NT.

Hook the IDT , watch out for SMP issues, it’s tricky. Define your own
service interface , read IA32 Manuals regarding IOAPIC and Interrupt
priority & assignemnt to avoid conflicts on SMP systems .
