EVT_WDF_DEVICE_REPORTED_MISSING callback function (wdfpdo.h)

  • Article

[Applies to KMDF only]

A bus driver's EvtDeviceReportedMissing event callback function informs the driver that the framework has reported the physical device object (PDO) missing to the Plug and Play manager.

Syntax

EVT_WDF_DEVICE_REPORTED_MISSING EvtWdfDeviceReportedMissing;

void EvtWdfDeviceReportedMissing(
  [in] WDFDEVICE Device
)
{...}

Parameters

[in] Device

A handle to a framework device object.

Return value

None

Remarks

Framework-based bus drivers can provide an EvtDeviceReportedMissing callback function. To register this callback function, the bus driver must call WdfPdoInitSetEventCallbacks.

The framework calls EvtDeviceReportedMissing when processing a IRP_MN_QUERY_DEVICE_RELATIONS request for BusRelations from the PnP manager.

Most framework-based bus drivers do not need to provide this callback function.
