It doesn't quite work out that way. When 3317 * the first invocation of getopt finishes, it leaves optind pointing 3318 * to the argument _after_ the first argument in the second group. 3319 * So when the second invocation of getopt comes around, it doesn't 3320 * recognize the first argument it gets and then bails out. 3321 * 3322 * A nice alternative would be to have a flag for getopt that says 3323 * "just keep parsing arguments even when you encounter an unknown 3324 * argument", but there isn't one. So there's no real clean way to 3325 * easily parse two sets of arguments without having one invocation 3326 * of getopt know about the other. 3327 * 3328 * Without this hack, the first invocation of getopt would work as 3329 * long as the generic arguments are first, but the second invocation 3330 * (in the subfunction) would fail in one of two ways. In the case 3331 * where you don't set optreset, it would fail because optind may be 3332 * pointing to the argument after the one it should be pointing at. 3333 * In the case where you do set optreset, and reset optind, it would 3334 * fail because getopt would run into the first set of options, which 3335 * it doesn't understand. 3336 * 3337 * All of this would "sort of" work if you could somehow figure out 3338 * whether optind had been incremented one option too far.
