IoBuildFsdFree rule (wdm)

The IoBuildFsdFree rule specifies that a driver should use IoFreeIrp only on IRPs it previously allocated with IoBuildAsynchronousFsdRequest.

Driver model: WDM

How to test

At compile time

Run Static Driver Verifier and specify the IoBuildFsdFree 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.
