ingres_fetch_proc_return — Get the return value from a procedure call
This function is used to retrieve the return value following the execution of an Ingres database procedure (stored procedure).
注意: If used with a row-producing procedure, this function should be called after all the rows from the procedure have been fetched using ingres_fetch_array(), ingres_fetch_object() or ingres_fetch_row(). This function will eliminate any rows yet to be fetched should there be any left over.
