   This function is used to retrieve the return value following the execution
   of an Ingres database procedure (stored procedure).

    If used with a row-producing procedure, this function should be called after all the
    rows from the procedure have been fetched using
    <function>ingres_fetch_array</function>,
    <function>ingres_fetch_object</function> or
    <function>ingres_fetch_row</function>. This function will eliminate any
    rows yet to be fetched should there be any left over.
