It doesn't quite work out that way. When 2770 * the first invocation of getopt finishes, it leaves optind pointing 2771 * to the argument _after_ the first argument in the second group. 2772 * So when the second invocation of getopt comes around, it doesn't 2773 * recognize the first argument it gets and then bails out. 2774 * 2775 * A nice alternative would be to have a flag for getopt that says 2776 * "just keep parsing arguments even when you encounter an unknown 2777 * argument", but there isn't one. So there's no real clean way to 2778 * easily parse two sets of arguments without having one invocation 2779 * of getopt know about the other. 2780 * 2781 * Without this hack, the first invocation of getopt would work as 2782 * long as the generic arguments are first, but the second invocation 2783 * (in the subfunction) would fail in one of two ways. In the case 2784 * where you don't set optreset, it would fail because optind may be 2785 * pointing to the argument after the one it should be pointing at. 2786 * In the case where you do set optreset, and reset optind, it would 2787 * fail because getopt would run into the first set of options, which 2788 * it doesn't understand. 2789 * 2790 * All of this would "sort of" work if you could somehow figure out 2791 * whether optind had been incremented one option too far.
