EvtDeviceSurpriseRemoval

A driver's EvtDeviceSurpriseRemoval event callback function performs any operations that are needed after a device has been unexpectedly removed from the system or after a driver reports that the device has failed.

構文

EVT_WDF_DEVICE_SURPRISE_REMOVAL EvtDeviceSurpriseRemoval;

VOID EvtDeviceSurpriseRemoval(
  __in  WDFDEVICE Device
)
{ ... }

パラメーター

Device [in]

A handle to a framework device object.

戻り値

None

解説

To register an EvtDeviceSurpriseRemoval callback function, a driver must call WdfDeviceInitSetPnpPowerEventCallbacks.

The framework does not synchronize the EvtDeviceSurpriseRemoval callback function with other PnP and power management callback functions. For information about how the framework synchronizes the execution of a driver's event callback functions, see Using Automatic Synchronization.

For more information about when the framework calls this callback function, and for more information about synchronization issues, see A User Unplugs a Device.

The function type is declared in Wdfdevice.h, as follows.

typedef VOID
 (EVT_WDF_DEVICE_SURPRISE_REMOVAL)(
    IN WDFDEVICE Device
    );

To define an EvtDeviceSurpriseRemoval callback function that is named MyDeviceSurpriseRemoval, you must first provide a function declaration that SDV and other verification tools require, as follows:

EVT_WDF_DEVICE_SURPRISE_REMOVAL  MyDeviceSurpriseRemoval;

Then, implement your callback function as follows:

VOID
 MyDeviceSurpriseRemoval (
    IN WDFDEVICE  Device
    )
  {...}
