Syntax

NDK_FN_QUERY_EXTENSION_INTERFACE NdkFnQueryExtensionInterface;

NTSTATUS NdkFnQueryExtensionInterface(
  [in]  NDK_OBJECT_HEADER *pNdkObject,
  [in]  GUID *ExtensionInterfaceID,
  [in]  NDK_VERSION ExtensionInterfaceVersion,
  [out] NDK_EXTENSION_INTERFACE *pExtensionInterface
)
{...}

Parameters

[in] pNdkObject

A pointer to the object header (NDK_OBJECT_HEADER) for the object being queried.

[in] ExtensionInterfaceID

A pointer to the GUID that identifies the extension interface.

[in] ExtensionInterfaceVersion

The requested version (NDK_VERSION) of the extension interface.

[out] pExtensionInterface

A pointer to an NDK_EXTENSION_INTERFACE structure that the provider initialized if the function returns STATUS_SUCCESS.

Return value

Return code	Description
STATUS_SUCCESS	The operation completed successfully.
STATUS_NOT_SUPPORTED	The function is not supported.

Remarks

Each NDK object contains an NdkQqueryExtensionInterface (NDK_FN_QUERY_EXTENSION_INTERFACE) function pointer in its object type-specific function dispatch table. NdkQqueryExtensionInterface queries extended interfaces that are supported by the object type. There are currently no standard extended interfaces defined. An extension interface is identified by a GUID and represented as a pointer to a function dispatch table.
