WdfFdoInitSetDefaultChildListConfig function (wdffdo.h)

[Applies to KMDF only]

The WdfFdoInitSetDefaultChildListConfig method configures a bus driver's default child list.

Syntax

VOID WdfFdoInitSetDefaultChildListConfig(
 [in, out] PWDFDEVICE_INIT DeviceInit,
 [in] PWDF_CHILD_LIST_CONFIG Config,
 [in, optional] PWDF_OBJECT_ATTRIBUTES DefaultChildListAttributes
);

Parameters

[in, out] DeviceInit

A pointer to a WDFDEVICE_INIT structure that the driver obtained from its EvtDriverDeviceAdd callback function.

[in] Config

A pointer to a driver-allocated WDF_CHILD_LIST_CONFIG structure.

[in, optional] DefaultChildListAttributes

A pointer to a caller-allocated WDF_OBJECT_ATTRIBUTES structure that contains object attributes for the child-list object that represents the driver's default child list. This parameter is optional and can be WDF_NO_OBJECT_ATTRIBUTES.

Return value

None

Remarks

A bus driver must call WdfFdoInitSetDefaultChildListConfig before calling WdfDeviceCreate for the functional device object (FDO). For more information about calling WdfDeviceCreate, see Creating a Framework Device Object.

For more information about the WdfFdoInitSetDefaultChildListConfig method, see Enumerating the Devices on a Bus.

Examples

The following code example initializes a WDF_CHILD_LIST_CONFIG structure and then calls WdfFdoInitSetDefaultChildListConfig.

WDF_CHILD_LIST_CONFIG config;

WDF_CHILD_LIST_CONFIG_INIT(
 &config,
 sizeof(MY_IDENTIFICATION_DESCRIPTION),
 My_EvtDeviceListCreatePdo
 );
config.EvtChildListIdentificationDescriptionDuplicate = My_EvtChildListIdentificationDescriptionDuplicate;
config.EvtChildListIdentificationDescriptionCompare = My_EvtChildListIdentificationDescriptionCompare;
config.EvtChildListIdentificationDescriptionCleanup = My_EvtChildListIdentificationDescriptionCleanup;

WdfFdoInitSetDefaultChildListConfig(
 DeviceInit,
 &config,
 WDF_NO_OBJECT_ATTRIBUTES
 );
