IoAllocateIrpSignalEventInCompletion rule

The IoAllocateIrpSignalEventInCompletion rule specifies that the driver should call KeSetEvent in the completion routine when the Irp->PendingReturned flag is set and the completion routine is processing a locally created asynchronous IRP.

How to test

At compile time

Run Static Driver Verifier and specify the IoAllocateIrpSignalEventInCompletion 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.

For more information, see Using Static Driver Verifier to Find Defects in Drivers.
