在ramfs 里面通过minini 操作，出现bad file

    for (int var = 0; var < pDbase->nDI; var++)
    {
        sprintf(key,"%03d",var);
        ini_putl("DI.FilterTime",key,pDIPara->wFilterTime,"/tmp/para.ini");
    }
    memset(key,0,DB_KEY_LEN);
    for (int var = 0; var < pDbase->nDI; var++)
    {
        sprintf(key,"%03d",var);
        ini_putl("DI.Class",key,pDIPara->wClass,"/tmp/para.ini");
    }
