Ok, thanks :-) I really have to wonder why Posix didn't say that readdir() returning NULL on end-of-directory simply *sets* errno to 0. Or even why it wouldn't allow both behaviors (it doesn't change anything if you set errno to 0 yourself before, and setting it to 0 is what you need in all practical cases), recommend the saner one, and so gradually phase out the old behavior. I even wonder why some systems don't implement a "readdir1()" function that does "errno=0; readdir()"... But enough pointless ranting :-) A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
