RE: How can a driver force a thread to wait for an ev-ent?

Isn’t the handle process specific, so can only be signaled in the
process/thread context. I guess I mean, would the driver have to get a
“kernel” specific handle?

Let the user create the Event and pass the Handle to the Kernel…
and let the User wait on that event and kernel signals it! rather thans
doing the other way round!

Subject: [ntdev] How Do I Get A Kernel driver Signal a thread?

I have a driver that acquires data. Currently, the user
reads/writes from/to
this driver at will. Some users have requested some sort of
notification or
signaling. I want to ty two approches and would like suggestions on
approches and kernel calls to use. The kernel driver is for
Windows NT 4.0
and Windows 2000.

  1. I want to create some sort of object in the kernel driver that the
    calling user thread can block on till the data/event occurs.
  2. Alternatively, I would like to have the ability to call a
    user function
    in user mode from the kernel driver.
  3. How would I handle cleanup if the user mode application is aborted
    abuptly?

Thanks for your help.
