IoSetCompletionExCompleteIrp rule (wdm)

  • Artikkel

The IoSetCompletionExCompleteIrp rule specifies that the IoSetCompletionRoutineEx routine returns an NTSTATUS value. The driver must check this value to determine if the IoCompletion routine was successfully registered before calling IoCallDriver or PoCallDriver and if IoSetCompletionRoutineEx fails then the IRP should be completed and the dispatch routine should return.

Driver model: WDM

Bug check(s) found with this rule: Bug Check 0xC4: DRIVER_VERIFIER_DETECTED_VIOLATION (0x0004100F)

How to test

At compile time
