More likely it was too complex! :-) That post would have been appropriate on comp.lang.python, this list is usually more concerned with basic questions like "how does a while loop work?"! But we do usually try to answer the harder stuff, if you didn't get a response sorry. I for one didn't even notice the original post, not that I could have helped much! :-) > It turns out that one needs to pass a 3rd parameter (and possibly a > 4th) if one expects a result value from calling ioctl.
