One Pioneer DVD-R drive * returns more data than the command asked for. * * So, since there are numerous devices that just don't work * right with the full inquiry size, we don't send the full size. * * - The second reason not to use the full inquiry data length is * that we don't need it here. The only reason we issue a * standard inquiry is to get the vendor name, device name, * and revision so scsi_print_inquiry() can print them. * * If, at some point in the future, more inquiry data is needed for * some reason, this code should use a procedure similar to the * probe code. i.e., issue a short inquiry, and determine from * the additional length passed back from the device how much * inquiry data the device supports.

It doesn't quite work out that way. When * the first invocation of getopt finishes, it leaves optind pointing * to the argument _after_ the first argument in the second group. * So when the second invocation of getopt comes around, it doesn't * recognize the first argument it gets and then bails out. * * A nice alternative would be to have a flag for getopt that says * "just keep parsing arguments even when you encounter an unknown * argument", but there isn't one. So there's no real clean way to * easily parse two sets of arguments without having one invocation * of getopt know about the other. * * Without this hack, the first invocation of getopt would work as * long as the generic arguments are first, but the second invocation * (in the subfunction) would fail in one of two ways. In the case * where you don't set optreset, it would fail because optind may be * pointing to the argument after the one it should be pointing at. * In the case where you do set optreset, and reset optind, it would * fail because getopt would run into the first set of options, which * it doesn't understand. * * All of this would "sort of" work if you could somehow figure out * whether optind had been incremented one option too far. The * mechanics of that, however, are more daunting than just giving * both invocations all of the expect options for either invocation. * * Needless to say, I wouldn't mind if someone invented a better * (non-GPL!) command line parsing interface than getopt. I * wouldn't mind if someone added more knobs to getopt to make it * work better. Who knows, I may talk myself into doing it someday, * if the standards weenies let me.
