## Description

Rasqal Result Row class.

### rasqal_new_row_for_size ()

    rasqal_row *        rasqal_new_row_for_size             (rasqal_world *world,
                                                             int size);

Constructor - Create a new query result row of a given size

`world` : | rasqal_world
`size` : | width of row
Returns : | a new query result row or NULL on failure

### rasqal_free_row ()

    void                rasqal_free_row                     (rasqal_row *row);

Destructor - Free a query result row object.

`row` : | query result row

### rasqal_row_set_value_at ()

    int                 rasqal_row_set_value_at             (rasqal_row *row,
                                                             int offset,
