WdfDeviceInitSetPnpPowerEventCallbacks function

Description

[Applies to KMDF and UMDF]

The WdfDeviceInitSetPnpPowerEventCallbacks method registers a driver's Plug and Play and power management event callback functions.

Parameters

DeviceInit [in]

A caller-supplied pointer to a WDFDEVICE_INIT structure.

PnpPowerEventCallbacks [in]

A pointer to a caller-initialized WDF_PNPPOWER_EVENT_CALLBACKS structure.

Remarks

If your driver calls WdfDeviceInitSetPnpPowerEventCallbacks, it must do so before it calls WdfDeviceCreate.

For more information about calling WdfDeviceCreate, see Creating a Framework Device Object.

Examples

The following code example initializes a WDF_PNPPOWER_EVENT_CALLBACKS structure and then calls WdfDeviceInitSetPnpPowerEventCallbacks.

WDF_PNPPOWER_EVENT_CALLBACKS  pnpPowerCallbacks;

WDF_PNPPOWER_EVENT_CALLBACKS_INIT(&pnpPowerCallbacks);
pnpPowerCallbacks.EvtDevicePrepareHardware = SerialEvtPrepareHardware;
pnpPowerCallbacks.EvtDeviceReleaseHardware = SerialEvtReleaseHardware;
pnpPowerCallbacks.EvtDeviceD0Entry = SerialEvtDeviceD0Entry;
pnpPowerCallbacks.EvtDeviceD0Exit = SerialEvtDeviceD0Exit;
WdfDeviceInitSetPnpPowerEventCallbacks(
                                       DeviceInit,
                                       &pnpPowerCallbacks
                                       );
