The InitFreeDeviceCreate rule specifies that a driver must call WdfDeviceInitFree instead of WdfDeviceCreate if an error occurs in one of the device object initialization methods and if the driver received the WDFDEVICE_INIT structure from a call to WdfControlDeviceInitAllocate.
Driver model: KMDF
How to test
| At compile time |
|---|
Run Static Driver Verifier and specify the InitFreeDeviceCreate rule. Use the following steps to run an analysis of your code:
