WdfRequestSendSyncAtDispatch rule (kmdf)

  • Makale

The WdfRequestSendSyncAtDispatch rule verifies that the WdfRequestSend function is sent at the correct IRQL priority level.

If the driver sets the WDF_REQUEST_SEND_OPTION_SYNCHRONOUS flag, it must call the WdfRequestSend function at IRQL = PASSIVE_LEVEL. If this flag is not set, the driver must call the WdfRequestSend function at IRQL = DISPATCH_LEVEL.

Note

This rule tests the same conditions as the WdfRequestSendSyncAtDispatch2 rule, but it uses a different harness to test different code paths.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the WdfRequestSendSyncAtDispatch 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.
