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. 3359 * 3360 * KDM, September 8th, 1998 3361 */ 3362 if (subopt != NULL) 3363 sprintf(combinedopt, "%s%s", mainopt, subopt); 3364 else 3365 sprintf(combinedopt, "%s", mainopt); 3366 3367 /* 3368 * For these options we do not parse optional device arguments and 3369 * we do not open a passthrough device. 3370 */ 3371 if ((cmdlist == CAM_CMD_RESCAN) 3372 || (cmdlist == CAM_CMD_RESET) 3373 || (cmdlist == CAM_CMD_DEVTREE) 3374 || (cmdlist == CAM_CMD_USAGE) 3375 || (cmdlist == CAM_CMD_DEBUG)) 3376 devopen = 0; 3377 3378 #ifndef MINIMALISTIC 3379 if ((devopen == 1) 3380 && (argc > 2 && argv[2][0] != '-')) { 3381 char name[30]; 3382 int rv; 3383 3384 /* 3385 * First catch people who try to do things like: 3386 * camcontrol tur /dev/da0 3387 * camcontrol doesn't take device nodes as arguments. 3388 */ 3389 if (argv[2][0] == '/') { 3390 warnx("%s is not a valid device identifier", argv[2]); 3391 errx(1, "please read the camcontrol(8) man page"); 3392 } else if (isdigit(argv[2][0])) { 3393 /* device specified as bus:target[:lun] */ 3394 rv = parse_btl(argv[2], &bus, &target, &lun, &arglist); 3395 if (rv < 2) 3396 errx(1, "numeric device specification must " 3397 "be either bus:target, or " 3398 "bus:target:lun"); 3399 optstart++; 3400 } else { 3401 if (cam_get_device(argv[2], name, sizeof name, &unit) 3402 == -1) 3403 errx(1, "%s", cam_errbuf); 3404 device = strdup(name); 3405 arglist |= CAM_ARG_DEVICE | CAM_ARG_UNIT; 3406 optstart++; 3407 } 3408 } 3409 #endif /* MINIMALISTIC */ 3410 /* 3411 * Start getopt processing at argv[2/3], since we've already 3412 * accepted argv[1..2] as the command name, and as a possible 3413 * device name. 3414 */ 3415 optind = optstart; 3416 3417 /* 3418 * Now we run through the argument list looking for generic 3419 * options, and ignoring options that possibly belong to 3420 * subfunctions. 3421 */ 3422 while ((c = getopt(argc, argv, combinedopt))!= -1){ 3423 switch(c) { 3424 case 'C': 3425 retry_count = strtol(optarg, NULL, 0); 3426 if (retry_count < 0) 3427 errx(1, "retry count %d is < 0", 3428 retry_count); 3429 arglist |= CAM_ARG_RETRIES; 3430 break; 3431 case 'E': 3432 arglist |= CAM_ARG_ERR_RECOVER; 3433 break; 3434 case 'n': 3435 arglist |= CAM_ARG_DEVICE; 3436 tstr = optarg; 3437 while (isspace(*tstr) && (*tstr != '\0')) 3438 tstr++; 3439 device = (char *)strdup(tstr); 3440 break; 3441 case 't': 3442 timeout = strtol(optarg, NULL, 0); 3443 if (timeout < 0) 3444 errx(1, "invalid timeout %d", timeout); 3445 /* Convert the timeout from seconds to ms */ 3446 timeout *= 1000; 3447 arglist |= CAM_ARG_TIMEOUT; 3448 break; 3449 case 'u': 3450 arglist |= CAM_ARG_UNIT; 3451 unit = strtol(optarg, NULL, 0); 3452 break; 3453 case 'v': 3454 arglist |= CAM_ARG_VERBOSE; 3455 break; 3456 default: 3457 break; 3458 } 3459 } 3460 3461 #ifndef MINIMALISTIC 3462 /* 3463 * For most commands we'll want to open the passthrough device 3464 * associated with the specified device.
