    char **grouplist = kdk_conf_list_group(id);


    ASSERT_NOT_NULL(grouplist, -1);


    char *tmpgroup;


    int index = 0;


    while ((tmpgroup = grouplist[index]))


    {


        printf("Group: %s0, tmpgroup);


        keylist = kdk_conf_list_key(id, tmpgroup);


        ASSERT_NOT_NULL(keylist, -1);


        char *tmpkey;


        int k_index = 0;


        while ((tmpkey = keylist[k_index]))


        {


            const char *tmpval = kdk_conf_get_value(id, tmpgroup, tmpkey);


            printf("%s = %s0, tmpkey , tmpval);


            k_index ++;


        }


        kdk_config_freeall(keylist);


        index ++;


    }


    kdk_conf_destroy(id);


    kdk_config_freeall(grouplist);


    return 0;
}
