Windows Driver Kit DDI reference (nc-wdfdriver-evt_wdf_driver_unload)

EVT_WDF_DRIVER_UNLOAD callback function

Description

[Applies to KMDF and UMDF]

A driver's EvtDriverUnload event callback function performs operations that must take place before the driver is unloaded.

Parameters

Driver [in]

A handle to a framework driver object.

Remarks

A driver registers an EvtDriverUnload callback function when it calls WdfDriverCreate.

The EvtDriverUnload callback function must deallocate any non-device-specific system resources that the driver's DriverEntry routine allocated.

The framework does not call a driver's EvtDriverUnload callback function if the driver's DriverEntry routine returns an error status value.
