short options?

Hi @albmac .

Short options: -d, -e, -i, -o. See https://github.com/ImageProcessing-ElectronicPublications/jpeg-decomp .

    struct option long_options[] =
    {
        {"decode",       no_argument,   &decode, 'd'},
        {"encode",       no_argument,   &encode, 'e'},
        {"fin",    required_argument,       0, 'i'},
        {"fout",   required_argument,       0, 'o'},
        {0, 0, 0, 0}
    };
    while ((c = getopt_long (argc, argv, "dei:o:",long_options,&option_index)) != -1)
        switch (c)
        {
        case 'd':   //decode
            decode = 1;
            break;
        case 'e':   //encode
            encode = 1;
            break;
        case 'i':   //fin
            strncpy(filein,optarg,sizeof(filein)-1);
            break;
        case 'o':   //fout
            strncpy(fileout,optarg,sizeof(fileout)-1);
            break;
        case '?':
            fprintf (stderr,"option error");
            return;
        default:

            break;
        }
...
    if(encode==0&&decode==0)
    {
        printf("Usage:\n");
        printf("%s --decode or --encode --fin <file> --fout <file>\n", argv[0]);
        printf("or:\n");
        printf("%s -d|-e -i <file> -o <file>\n", argv[0]);
        return;
    }
