Functions

WDF_QUERY_INTERFACE_CONFIG_INIT The WDF_QUERY_INTERFACE_CONFIG_INIT function initializes a driver's WDF_QUERY_INTERFACE_CONFIG structure.
WdfDeviceAddQueryInterface The WdfDeviceAddQueryInterface method creates a driver-defined interface that other drivers can query and use.
WdfDeviceInterfaceDereferenceNoOp The WdfDeviceInterfaceDereferenceNoOp method can be used for driver-defined interfaces that do not require reference counts.
WdfDeviceInterfaceReferenceNoOp The WdfDeviceInterfaceReferenceNoOp method can be used for driver-defined interfaces that do not require reference counts.

Callback functions

EVT_WDF_DEVICE_PROCESS_QUERY_INTERFACE_REQUEST A driver's EvtDeviceProcessQueryInterfaceRequest event callback function examines another driver's request for access to a driver-defined interface, before the framework passes the interface to the requesting driver.

Structures

WDF_QUERY_INTERFACE_CONFIG The WDF_QUERY_INTERFACE_CONFIG structure describes a driver-defined interface.
