LowerDriverReturn rule (wdm)

The LowerDriverReturn rule specifies that after using PoCallDriver or IoCallDriver to call a lower driver, the driver saves the return status from the call and passes the return status that it received to the dispatch routine.

These conditions are not applied if the driver calls IoCompleteRequest or IoMarkIrpPending.

Driver model: WDM

How to test

At compile time
Run Static Driver Verifier and specify the LowerDriverReturn rule. Use the following steps to run an analysis of your code: Prepare your code (use role type declarations). Run Static Driver Verifier. View and analyze the results. For more information, see Using Static Driver Verifier to Find Defects in Drivers.
