InitFreeDeviceCreateType4 rule (kmdf)

The InitFreeDeviceCreateType4 rule specifies that a driver must call WdfDeviceInitFree if the driver encounters an error while it calls WdfDeviceCreate and if the driver received the WDFDEVICE_INIT structure from a call to WdfControlDeviceInitAllocate.

How to test

At compile time

Run Static Driver Verifier and specify the InitFreeDeviceCreateType4 rule.

  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
