Additional Information

For information about device stacks, see the Windows Driver Kit (WDK) documentation.


If DeviceObject specifies the name of the device but supplies no prefix, the prefix "\Device\" is assumed. Note that this command will check to see if DeviceObject is a valid address or device name before using the expression evaluator.

Here is an example:

 !DevObj   !DrvObj            !DevExt   ObjectName
