C getopt multiple value

Question

My argument is like this

./a.out -i file1 file2 file3

How can I utilize getopt() to get 3 (or more) input files? I\'m doing s

Answer 1

I looked and tried the code above, but I found my solution a little easier and worked better for me:

The handling I wanted was:

-m mux_i2c_group mux_i2c_out

(2 arguments required).

Here's how it panned out for me:

case 'm':
    mux_i2c_group = strtol(optarg, &ch_p, 0);

    if (optind < argc && *argv[optind] != '-'){
        mux_i2c_out = strtol(argv[optind], NULL, 0);
        optind++;
    } else {
        fprintf(stderr, "\n-m option require TWO arguments  "
                        "\n\n");
        usage();
    }

    use_mux_flag = 1;
    break;

This grabbed the first value form me as normal and then just looked for the second, REQUIRED value.
