Hi All
Does anybody have any idea of callbacks registered with
IoRegisterPlugPlayNotification are called in context of which thread.
Is it System thread or any arbitrary thread?
Cheers
Deepak
It can be either. What is you underlying question/problem?

I had a callack registerd for an interface.
In the callback I am calling IoGetDeviceObjectPointer which according to
MSDN should be called in context of system thread.
So I was thinking if the callback is already into system then why issuing a
call to change the context.
Cheers

Pretty funny, I had never noticed that restriction before. It appears to be
a leftover from the NT4/Win2K days where the ZwCreateFile call that
IoGetDeviceObjectPointer makes didn’t specify OBJ_KERNEL_HANDLE.
