Q: DeviceTree from OSR

NTFSD
1

I’m using DeviceTree that I downloaded from OSR while I’m developing my disk driver.
When I’m in Driver View mode (the default view mode) and highlight my driver, I am be able to see all my device objects in the Device List.
There are several columns. Device_Name, Device Object, Handle, Ptrs, Refs, Attached, FSD.
My interesting is how do you get the numbers for Handle and Refs.

I don’t think that this value come from the DEVICE_OBJECT.ReferenceCount because I’m getting diffrance value in my driver when I’m printing it and in the DeviceTree.

Any suggestions,

Ophir.

Right. The ref counts displayed by DeviceTree are the OBJECT MANAGER
reference counts. Not the I/O Manager’s ref counts on the device object, as
maintained in DeviceObject->ReferenceCount.
