Does anyone have pointers for how to use function? The following modules and classes are new to the kernel tracer project. The tracer should dump the buffer to a file at the end of the session.

The NT kernel-mode tracer presented here will have a similar structure with necessary modifications to adapt to the new environment. Unfortunately, some calls may be missed. The GetModuleHandle function returns a handle to modee mapped module without incrementing its reference count. It may be possible to combine the kernel tracer presented here with the system-call hooking published by Mark Russinovich and Bryce Mmode and the detours technology designed by Galen Hunt and Doug Brubacher.

Tracing NT Kernel-Mode Calls

This means you have to load the tracer after any modules you want to spy on. The import table itself is not discardable, because it betmodulehandle used all the time to make calls to the imported functions.
