DESCRIPTION

16       mmv_inc_value provides a convenient way of updating a value returned by
17       the  mmv_lookup_value_desc.   addr  is  the   address   returned   from
18       mmv_stats_init().

20       The value of the inc is internally cast to match the type of the metric
21       and then added to the previous value of the metric.
