IrqlReturn rule (wdm)

  • Artikel

The IrqlReturn rule specifies that the driver's dispatch routines return at the same IRQL at which they were called. For more information about the IRQLs at which dispatch routines are properly called, see Dispatch Routines and IRQLs.

Driver model: WDM

How to test

At compile time

Run Static Driver Verifier and specify the IrqlReturn 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.
