Shorter code is not a virtue. A code, that requires a special note, is a vice. AFAIK, the order of . and .. is not guaranteed in all systems

@YourCommonSense, "Shorter code is not a virtue": true. But simpler code is. Moreover, the order has nothing to do with this. Their existence only is required (and guaranteed). If the directory has more than 2 entries it is not empty. Nobody said anything about order. This code makes sure that, no matter what happens, closedir is called. And can very easily be modified to return error information.
