How to communicate wih application in the dispatch routine?

NTDEV
1

I want to communicate with user application in the dispatch routine and wait in the dispatch routine until the user application’s some job is complete.

but I can’t use the mutex on the dispatch routine which is controlled by user application
because dispatch routine’s running level is to high…
Is there any method for waiting the user app’s signal on the dispatch routine?

You cannot wait at DISPATCH_LEVEL.

What problem are you trying to solve by that?

Even if you could wait, that is a bad idea. Waiting leaves your driver susceptible to app bugs. You should inform the app and then have the app send another Io indicating it is done.

My first reaction is that there is something wrong with your design. The
actions you describe should not be necessary. Reconsider your design.
