[Applies to KMDF only]

The WDF_CHILD_LIST_CONFIG_INIT function initializes a WDF_CHILD_LIST_CONFIG structure.

Syntax

void WDF_CHILD_LIST_CONFIG_INIT(
  [out] PWDF_CHILD_LIST_CONFIG           Config,
  [in]  ULONG                            IdentificationDescriptionSize,
  [in]  PFN_WDF_CHILD_LIST_CREATE_DEVICE EvtChildListCreateDevice
);

Parameters

[out] Config

A pointer to a driver-allocated WDF_CHILD_LIST_CONFIG structure.

[in] IdentificationDescriptionSize

The size, in bytes, of each child device's identification description.

[in] EvtChildListCreateDevice

The address of a driver-supplied EvtChildListCreateDevice event callback function.

Return value

None

Remarks

The WDF_CHILD_LIST_CONFIG_INIT function zeros the specified WDF_CHILD_LIST_CONFIG structure and sets the structure's Size member. Then it sets the IdentificationDescriptionSize and EvtChildListCreateDevice members to the specified values.
