The WDF_QUERY_INTERFACE_CONFIG_INIT function initializes a driver's WDF_QUERY_INTERFACE_CONFIG structure.

Syntax

void WDF_QUERY_INTERFACE_CONFIG_INIT(
  [out]          PWDF_QUERY_INTERFACE_CONFIG                    InterfaceConfig,
  [in]           PINTERFACE                                     Interface,
  [in]           const GUID                                     *InterfaceType,
  [in, optional] PFN_WDF_DEVICE_PROCESS_QUERY_INTERFACE_REQUEST EvtDeviceProcessQueryInterfaceRequest
);

Parameters

[out] InterfaceConfig

A pointer to the driver's WDF_QUERY_INTERFACE_CONFIG structure.

[in] Interface

A pointer to an INTERFACE structure.

[in] InterfaceType

A pointer to the GUID that identifies the interface.

[in, optional] EvtDeviceProcessQueryInterfaceRequest
