671 * Note that although the size of the inquiry buffer is the full

673 * that we have allocated SHORT_INQUIRY_LENGTH bytes. There are
674 * two reasons for this:
675 *
676 * - The SCSI spec says that when a length field is only 1 byte,
677 * a value of 0 will be interpreted as 256. Therefore
678 * scsi_inquiry() will convert an inq_len (which is passed in as
679 * a u_int32_t, but the field in the CDB is only 1 byte) of 256
680 * to 0. Evidently, very few devices meet the spec in that
681 * regard. Some devices, like many Seagate disks, take the 0 as
682 * 0, and don't return any data. One Pioneer DVD-R drive
683 * returns more data than the command asked for.
684 *
685 * So, since there are numerous devices that just don't work
686 * right with the full inquiry size, we don't send the full size.
687 *
688 * - The second reason not to use the full inquiry data length is
689 * that we don't need it here. The only reason we issue a
690 * standard inquiry is to get the vendor name, device name,
691 * and revision so scsi_print_inquiry() can print them.
692 *
693 * If, at some point in the future, more inquiry data is needed for
694 * some reason, this code should use a procedure similar to the
695 * probe code. i.e., issue a short inquiry, and determine from
696 * the additional length passed back from the device how much
697 * inquiry data the device supports. Once the amount the device
698 * supports is determined, issue an inquiry for that amount and no
699 * more.

3842 * the first invocation of getopt finishes, it leaves optind pointing
3843 * to the argument _after_ the first argument in the second group.
3844 * So when the second invocation of getopt comes around, it doesn't
3845 * recognize the first argument it gets and then bails out.
3846 *
3847 * A nice alternative would be to have a flag for getopt that says
3848 * "just keep parsing arguments even when you encounter an unknown
3849 * argument", but there isn't one. So there's no real clean way to
3850 * easily parse two sets of arguments without having one invocation
3851 * of getopt know about the other.
3852 *
3853 * Without this hack, the first invocation of getopt would work as
3854 * long as the generic arguments are first, but the second invocation
3855 * (in the subfunction) would fail in one of two ways. In the case
3856 * where you don't set optreset, it would fail because optind may be
3857 * pointing to the argument after the one it should be pointing at.
3858 * In the case where you do set optreset, and reset optind, it would
3859 * fail because getopt would run into the first set of options, which
3860 * it doesn't understand.
3861 *
3862 * All of this would "sort of" work if you could somehow figure out
3863 * whether optind had been incremented one option too far. The
3864 * mechanics of that, however, are more daunting than just giving
3865 * both invocations all of the expect options for either invocation.
3866 *
3867 * Needless to say, I wouldn't mind if someone invented a better
3868 * (non-GPL!) command line parsing interface than getopt. I
3869 * wouldn't mind if someone added more knobs to getopt to make it
3870 * work better. Who knows, I may talk myself into doing it someday,
3871 * if the standards weenies let me. As it is, it just leads to
3872 * hackery like this and causes people to avoid it in some cases.
