今天想测试测 rt-thread rdb功能，按下列方式，打开编译开关
RT-Thread online packages → tools packages

编译时，报错：
.\build\keil\Obj t-thread.axf: Error: L6218E: Undefined symbol rt_dstr_append_printf (referred from rdbd_file.o).

定位到rdbd.c文件第833行，如下：
            fullpath = (rt_dstr_t *)rt_dstr_sprintf(fullpath, "/%s", dir->d_name);
        }
        else
        {
            fullpath = (rt_dstr_t *)rt_dstr_sprintf(fullpath, "%s/%s", pathname, dir->d_name);
        }
        if (stat(fullpath->str, &filestat) == -1)
        {
            LOG_E("cannot access the file %s", fullpath->str);
            return list;
        }
        if ((filestat.st_mode & S_IFMT) == S_IFDIR)
        {
            temp_list = get_file_list(fullpath->str);
            list = (rt_dstr_t ***)rt_dstr_append_printf**(list, "%s", temp_list->str);
            rt_dstr_del(temp_list);
            temp_list = RT_NULL;
        }
        else
        {
            list = (rt_dstr_t *)rt_dstr_append_printf(list, "%s<br>", fullpath->str);
        }
        rt_dstr_del(fullpath);
        fullpath = RT_NULL;
    }
    closedir(root_dir);
    return list;
}

搜索rt_dstr_append_printf定义，没有找到，请问这个函数定义在哪里？
