Hi,

I am working on a set of device drivers, (extending the functionality of
some existing ones acutally), and have run into a bit of a snag..... any
help appreciated.  I am working with the Windows NT/2000 driver development
kit.

Scenario:

I want notification to the user when a particular event occurs at a low
level driver (a VxD).  I can use SendMessage to notify the user app, but
cannot find out how to signal a DLL thread from the VxD.


This is what I have tried:

I have created an event inside the DLL (using CreateEvent), and then have
set up a thread inside the DLL which is waiting for a signal from the VxD,
using WaitForSingleObject.
Via a call to DeviceIoControl, I have handed the VxD a pointer to this
event, which it stores.
I have hooked a function inside the VxD which is called at the right time
from lower down (this works fine).  It calls SetEvent() and returns.

Why it doesn't work:

To use SetEvent(), I include windows.h in the source code for the VxD.
During linking, it is unable to find this function...
I am very new to the way the windows2k driver development kit decides what
libraries etc it includes during this stage, plus I don't know if what I am
doing is _legal_.......

Any suggestions?  Better methods for signalling the DLL? More suitable
newsgroups to speak to?


Thanks in advance!
