I tries to implement the cancel safe queue but as soon as i am inserting the
irp (IoCsqInsertIrp) in the queue i get bsod. I am trying this to do while
sitting over the file system (In a file system filter driver).
Can i use the cancel-safe queue over the file system or shall i implement
queue of my own.
When i uses the IoCsqInsertIrpEx with IoCsqIntializeEx it gives the status
back as NT_SUCCESS(status) = 0.
Any suggesstions
Thanks in advance.

You should connect a correctly setup debugger and obtain complete bugcheck
information including stack trace with valid symbols and debug your problem.
With enough information somebody here might be able to help you.

I am creating the Csq queues in an Upper filesystem filter driver and i use
__try __except to locate that system crashes while inserting the IRP
(oCsqInsertIrp).
Thanks in advance

Vikram,
You aren’t setting up the queue correctly. Note the faulting address is
0x0.
I’d guess the CSQ package is trying to call one of your function
pointers and you haven’t set it up properly. Stack unwinds seem
problematic when you jump through zero.

Tony
