| STATUS_SUCCESS | The operation completed successfully. |
| STATUS_NOT_SUPPORTED | The function is not supported. |
| Other status codes | An error occurred. |
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.
