    Application snippet:

     
    const char * dbname = "SimpleDb";
     
    int main(int argc, char* argv[])
    {
        mco_db_h db;
        MCO_RET rc;
        mco_device_t       dev;
        mco_db_params_t    db_params;
        mco_trans_h t;
        mco_cursor_t c;
        MCO_CURSOR_TYPE ctype;
         
        ...
        rc = mco_db_open_dev( dbname, simple_get_dictionary(), &dev, 1, &db_params );
        if ( MCO_S_OK != rc )
        {
            rc = mco_db_connect(  dbname, &db );
            ...
            rc = mco_trans_start(db, MCO_READ_ONLY, MCO_TRANS_FOREGROUND, &t);
            if ( MCO_S_OK == rc )
            {
                ...
                A_list_cursor( t, &c);
                ...
                rc = mco_cursor_last( t, &c );
