The function is some kind of callback from the driver. That callback and irp is created
from other driver I guess by IoBuildDeviceControlRequest. I am setting my function
through a dll. Maybe there's some good way to get an irp.
My other drivers' work strictly depends on that function data.
I don't know - I've never written so complex drivers so far.
thanks anyway
