    Application snippet:
        
     
    int main(int argc, char** argv)
    {
        MCO_RET rc;
        mco_db_h db;
        mco_trans_h t;
        mco_cursor_t cursor;
        unsigned short struct_no = 1;
        unsigned short index_no = 5;
        ...
         
        rc = mco_trans_start(db, MCO_READ_ONLY, MCO_TRANS_FOREGROUND, &t);
        if ( MCO_S_OK == rc )
        {
            rc = mco_uda_cursor(t, struct_no, index_no, &cursor);
            for ( ; rc == MCO_S_OK; rc = mco_cursor_next(t, &cursor))
            {
                mco_uda_object_handle_t obj;
                /* get object handle */
                mco_uda_from_cursor(t, &cursor, &obj);
        
                ...
