This email sent to site_archiver@lists.apple.com "for(object = IOIteratorNext(iter); object != 0; object = IOIteratorNext(iter)) // iterate through all "IOATABlockStorageDriver"s" Perhaps you should also use "IOIteratorIsValid()"? The documentation states that: "Some iterators will be made invalid if changes are made to the structure they are iterating over. This function checks the iterator is still valid and should be called when IOIteratorNext returns zero." smime.p7s
