_WDF_PDO_EVENT_CALLBACKS structure

Description

[Applies to KMDF only]

The WDF_PDO_EVENT_CALLBACKS structure is the dispatch table for a bus driver's event callback functions.

Members

`Size`

The size, in bytes, of this structure.

`EvtDeviceResourcesQuery`

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

`EvtDeviceResourceRequirementsQuery`

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

`EvtDeviceEject`

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

`EvtDeviceSetLock`

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

`EvtDeviceEnableWakeAtBus`

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

`EvtDeviceDisableWakeAtBus`

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

`EvtDeviceReportedMissing`

A pointer to the driver's EvtDeviceReportedMissing event callback function, or NULL. The EvtDeviceReportedMissing member is available in version 1.11 and later versions of KMDF.

Remarks

The WDF_PDO_EVENT_CALLBACKS structure is used as input to WdfPdoInitSetEventCallbacks.

Drivers must call WDF_PDO_EVENT_CALLBACKS_INIT to initialize this structure.
