PnpSameDeviceObject rule (wdm)
The PnpSameDeviceObject rule specifies that the driver calls IoAttachDeviceToDeviceStack with a pointer to a valid target device object.
If the pointed-to device object is not standard, the driver violates this rule. This rule ensures that the driver correctly attaches to the device stack.
This rule does not verify the validity of the pointer to the source object.
Driver model: WDM
How to test
|At compile time|
Run Static Driver Verifier and specify the PnpSameDeviceObject rule.Use the following steps to run an analysis of your code:
