WdfIoQueueRetrieveFoundRequest rule (kmdf)

The WdfIoQueueRetrieveFoundRequest rule specifies that WdfIoQueueRetrieveFoundRequest method is called only after WdfIoQueueFindRequest is called and returned STATUS_SUCCESS and no WdfObjectDereference is called on the same request.

If WdfIoQueueFindRequest returns STATUS_SUCCESS it increments the reference count of the output request object, the driver must call WdfObjectDereference after it has finished using this request handle.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the WdfIoQueueRetrieveFoundRequest rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
