		* @endcode

		* Tests whether a node identifier refers to a node which:
		*
		* - exists in the devicetree, and
		* - has a status property as `okay`
		*
		* As usual, both a missing status and an `ok` status are treated as
		* `okay`.
		*
		* @param node_id a node identifier
		* @return 1 if the node has status as `okay`, 0 otherwise.
