There really aren't many other good 4037 * options (excuse the pun) for parsing options in a situation like 4038 * this. getopt is kinda braindead, so you end up having to run 4039 * through the options twice, and give each invocation of getopt 4040 * the option string for the other invocation. 4041 * 4042 * You would think that you could just have two groups of options. 4043 * The first group would get parsed by the first invocation of 4044 * getopt, and the second group would get parsed by the second 4045 * invocation of getopt. It doesn't quite work out that way. When 4046 * the first invocation of getopt finishes, it leaves optind pointing 4047 * to the argument _after_ the first argument in the second group. 4048 * So when the second invocation of getopt comes around, it doesn't 4049 * recognize the first argument it gets and then bails out. 4050 * 4051 * A nice alternative would be to have a flag for getopt that says 4052 * "just keep parsing arguments even when you encounter an unknown 4053 * argument", but there isn't one. So there's no real clean way to 4054 * easily parse two sets of arguments without having one invocation 4055 * of getopt know about the other. 4056 * 4057 * Without this hack, the first invocation of getopt would work as 4058 * long as the generic arguments are first, but the second invocation 4059 * (in the subfunction) would fail in one of two ways. In the case 4060 * where you don't set optreset, it would fail because optind may be 4061 * pointing to the argument after the one it should be pointing at. 4062 * In the case where you do set optreset, and reset optind, it would 4063 * fail because getopt would run into the first set of options, which 4064 * it doesn't understand. 4065 * 4066 * All of this would "sort of" work if you could somehow figure out 4067 * whether optind had been incremented one option too far. The 4068 * mechanics of that, however, are more daunting than just giving 4069 * both invocations all of the expect options for either invocation. 4070 * 4071 * Needless to say, I wouldn't mind if someone invented a better 4072 * (non-GPL!) command line parsing interface than getopt. I 4073 * wouldn't mind if someone added more knobs to getopt to make it 4074 * work better. Who knows, I may talk myself into doing it someday, 4075 * if the standards weenies let me.
