_WDF_PNPPOWER_EVENT_CALLBACKS structure

Description

[Applies to KMDF and UMDF]

The WDF_PNPPOWER_EVENT_CALLBACKS structure contains pointers to a driver's Plug and Play and power event callback functions.

Members

`Size`

The size, in bytes, of this structure.

`EvtDeviceD0Entry`

A pointer to the driver's EvtDeviceD0Entry event callback function, or NULL.

`EvtDeviceD0EntryPostInterruptsEnabled`

A pointer to the driver's EvtDeviceD0EntryPostInterruptsEnabled event callback function, or NULL.

`EvtDeviceD0Exit`

A pointer to the driver's EvtDeviceD0Exit event callback function, or NULL.

`EvtDeviceD0ExitPreInterruptsDisabled`

A pointer to the driver's EvtDeviceD0ExitPreInterruptsDisabled event callback function, or NULL.

`EvtDevicePrepareHardware`

A pointer to the driver's EvtDevicePrepareHardware event callback function, or NULL.

`EvtDeviceReleaseHardware`

A pointer to the driver's EvtDeviceReleaseHardware event callback function, or NULL.

`EvtDeviceSelfManagedIoCleanup`

A pointer to the driver's EvtDeviceSelfManagedIoCleanup event callback function, or NULL.

`EvtDeviceSelfManagedIoFlush`

A pointer to the driver's EvtDeviceSelfManagedIoFlush event callback function, or NULL.

`EvtDeviceSelfManagedIoInit`

A pointer to the driver's EvtDeviceSelfManagedIoInit event callback function, or NULL.

`EvtDeviceSelfManagedIoSuspend`

A pointer to the driver's EvtDeviceSelfManagedIoSuspend event callback function, or NULL.

`EvtDeviceSelfManagedIoRestart`

A pointer to the driver's EvtDeviceSelfManagedIoRestart event callback function, or NULL.

`EvtDeviceSurpriseRemoval`

A pointer to the driver's EvtDeviceSurpriseRemoval event callback function, or NULL.

`EvtDeviceQueryRemove`

A pointer to the driver's EvtDeviceQueryRemove event callback function, or NULL.

`EvtDeviceQueryStop`

A pointer to the driver's EvtDeviceQueryStop event callback function, or NULL.

`EvtDeviceUsageNotification`

A pointer to the driver's EvtDeviceUsageNotification event callback function, or NULL.

`EvtDeviceRelationsQuery`

A pointer to the driver's EvtDeviceRelationsQuery event callback function, or NULL.

`EvtDeviceUsageNotificationEx`

A pointer to the driver's EvtDeviceUsageNotificationEx event callback function, or NULL. The EvtDeviceUsageNotificationEx member is available in version 1.11 and later versions of KMDF. A driver can register either EvtDeviceRelationsQuery or EvtDeviceUsageNotificationEx, but not both.

Remarks

The WDF_PNPPOWER_EVENT_CALLBACKS structure is used as input to the WdfDeviceInitSetPnpPowerEventCallbacks method.

Your driver should initialize its WDF_PNPPOWER_EVENT_CALLBACKS structure by calling WDF_PNPPOWER_EVENT_CALLBACKS_INIT.
