RequestCompletedLocal rule (kmdf)

  • Article

The RequestCompletedLocal rule specifies that if an I/O request is not completed in any of the EvtIoDefault, EvtIoRead, EvtIoWrite, EvtIoDeviceControl, and EvtIoInternalDeviceControl callback functions, and if WdfRequestMarkCancelable was not called on the request within the callback function, there might be a problem with request completion in the driver's code.

This rule is only intended for the drivers for which the RequestCompleted rule is not applicable.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the RequestCompletedLocal 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.
