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.
