IoReuseIrp rule (wdm)

  • Article

The IoReuseIrp rule specifies that a driver should use IoReuseIrp only on IRPs that it previously allocated with IoAllocateIrp.

Driver model: WDM

How to test

At compile time

Run Static Driver Verifier and specify the IoReuseIrp 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.
