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

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

3316 * Ahh, getopt(3) is a pain.
3317 *
3318 * This is a gross hack. There really aren't many other good
3319 * options (excuse the pun) for parsing options in a situation like
3320 * this. getopt is kinda braindead, so you end up having to run
3321 * through the options twice, and give each invocation of getopt
3322 * the option string for the other invocation.
3323 *
3324 * You would think that you could just have two groups of options.
3325 * The first group would get parsed by the first invocation of
3326 * getopt, and the second group would get parsed by the second
3327 * invocation of getopt. It doesn't quite work out that way. When
3328 * the first invocation of getopt finishes, it leaves optind pointing
3329 * to the argument _after_ the first argument in the second group.
3330 * So when the second invocation of getopt comes around, it doesn't
3331 * recognize the first argument it gets and then bails out.
3332 *
3333 * A nice alternative would be to have a flag for getopt that says
3334 * "just keep parsing arguments even when you encounter an unknown
3335 * argument", but there isn't one. So there's no real clean way to
3336 * easily parse two sets of arguments without having one invocation
3337 * of getopt know about the other.
3338 *
3339 * Without this hack, the first invocation of getopt would work as
3340 * long as the generic arguments are first, but the second invocation
3341 * (in the subfunction) would fail in one of two ways. In the case
3342 * where you don't set optreset, it would fail because optind may be
3343 * pointing to the argument after the one it should be pointing at.
3344 * In the case where you do set optreset, and reset optind, it would
3345 * fail because getopt would run into the first set of options, which
3346 * it doesn't understand.
3347 *
3348 * All of this would "sort of" work if you could somehow figure out
3349 * whether optind had been incremented one option too far. The
3350 * mechanics of that, however, are more daunting than just giving
3351 * both invocations all of the expect options for either invocation.
3352 *
3353 * Needless to say, I wouldn't mind if someone invented a better
3354 * (non-GPL!) command line parsing interface than getopt. I
3355 * wouldn't mind if someone added more knobs to getopt to make it
3356 * work better. Who knows, I may talk myself into doing it someday,
3357 * if the standards weenies let me. As it is, it just leads to
3358 * hackery like this and causes people to avoid it in some cases.
