IOIterator early exit.


Hi again all,

    I am not sure whether this is a bug, design feature, or some brain dead thing I am doing, but if I do an early exit from an IOIterator loop, then I stop getting subsequent plugin notifications.   So, consider the following (in a callback from IOServiceAddMatchingNotification):

    while(usbDevice = IOIteratorNext(iterator)){
    blah;
    blah;

    return; (during first iteration ... ie, IOIteratorNext does not hit the end)
  }

    So I get the first call back ok, but the next time, no callback occurs.  I have to let the while condition actually fail (ie, set a flag to skip code in subsequent iterations) to make sure that IOIteratorNext hits the end.

    You can probably duplicate this quite easily by taking the example code from the dev. site, and just bunging in a return at the end of the loop.

Anyway, thought someone might have a comment on it.

Thanks,

Robert.
