732 * Note that although the size of the inquiry buffer is the full
733 * 256 bytes specified in the SCSI spec, we only tell the device
734 * that we have allocated SHORT_INQUIRY_LENGTH bytes. There are
735 * two reasons for this:
736 *
737 * - The SCSI spec says that when a length field is only 1 byte,
738 * a value of 0 will be interpreted as 256. Therefore
739 * scsi_inquiry() will convert an inq_len (which is passed in as
740 * a u_int32_t, but the field in the CDB is only 1 byte) of 256
741 * to 0. Evidently, very few devices meet the spec in that
742 * regard. Some devices, like many Seagate disks, take the 0 as
743 * 0, and don't return any data. One Pioneer DVD-R drive
744 * returns more data than the command asked for.
745 *
746 * So, since there are numerous devices that just don't work
747 * right with the full inquiry size, we don't send the full size.
748 *
749 * - The second reason not to use the full inquiry data length is
750 * that we don't need it here. The only reason we issue a
751 * standard inquiry is to get the vendor name, device name,
752 * and revision so scsi_print_inquiry() can print them.
753 *
754 * If, at some point in the future, more inquiry data is needed for
755 * some reason, this code should use a procedure similar to the
756 * probe code. i.e., issue a short inquiry, and determine from
757 * the additional length passed back from the device how much
758 * inquiry data the device supports. Once the amount the device
759 * supports is determined, issue an inquiry for that amount and no
760 * more.

3888 * Ahh, getopt(3) is a pain.
3889 *
3890 * This is a gross hack. There really aren't many other good
3891 * options (excuse the pun) for parsing options in a situation like
3892 * this. getopt is kinda braindead, so you end up having to run
3893 * through the options twice, and give each invocation of getopt
3894 * the option string for the other invocation.
3895 *
3896 * You would think that you could just have two groups of options.
3897 * The first group would get parsed by the first invocation of
3898 * getopt, and the second group would get parsed by the second
3899 * invocation of getopt. It doesn't quite work out that way. When
3900 * the first invocation of getopt finishes, it leaves optind pointing
3901 * to the argument _after_ the first argument in the second group.
3902 * So when the second invocation of getopt comes around, it doesn't
3903 * recognize the first argument it gets and then bails out.
3904 *
3905 * A nice alternative would be to have a flag for getopt that says
3906 * "just keep parsing arguments even when you encounter an unknown
3907 * argument", but there isn't one. So there's no real clean way to
3908 * easily parse two sets of arguments without having one invocation
3909 * of getopt know about the other.
3910 *
3911 * Without this hack, the first invocation of getopt would work as
3912 * long as the generic arguments are first, but the second invocation
3913 * (in the subfunction) would fail in one of two ways. In the case
3914 * where you don't set optreset, it would fail because optind may be
3915 * pointing to the argument after the one it should be pointing at.
3916 * In the case where you do set optreset, and reset optind, it would
3917 * fail because getopt would run into the first set of options, which
3918 * it doesn't understand.
3919 *
3920 * All of this would "sort of" work if you could somehow figure out
3921 * whether optind had been incremented one option too far. The
3922 * mechanics of that, however, are more daunting than just giving
3923 * both invocations all of the expect options for either invocation.
3924 *
3925 * Needless to say, I wouldn't mind if someone invented a better
3926 * (non-GPL!) command line parsing interface than getopt. I
3927 * wouldn't mind if someone added more knobs to getopt to make it
3928 * work better. Who knows, I may talk myself into doing it someday,
3929 * if the standards weenies let me. As it is, it just leads to
3930 * hackery like this and causes people to avoid it in some cases.
