- * posix_spawn_file_actions_addinherit_np

- * Description:	Add the "inherit" action to the object referenced by
- *		'file_actions' that will cause the file referenced by
- *		'filedes' to continue to be available in the spawned
- *		process via the same descriptor.
- *
- *		Inheritance is the normal default behaviour for
- *		file descriptors across exec and spawn; but if the
- *		POSIX_SPAWN_CLOEXEC_DEFAULT flag is set, the usual
- *		default is reversed for the purposes of the spawn
- *		invocation.  Any pre-existing descriptors that
- *		need to be made available to the spawned process can
- *		be marked explicitly as 'inherit' via this interface.
- *		Otherwise they will be automatically closed.
- *
- *		Note that any descriptors created via the other file
- *		actions interfaces are automatically marked as 'inherit'.
- *
- * Parameters:	file_actions		File action object to augment
- *		filedes			fd to inherit.
- *
- * Returns:	0			Success
- *		EBADF			The value specified by fildes is
- *					negative or greater than or equal to
- *					{OPEN_MAX}.
- *		ENOMEM			Insufficient memory exists to add to
- *					the spawn file actions object.
