C SYNOPSIS         top

       #include <pcp/pmapi.h>
       #include <pcp/mmv_stats.h>

DESCRIPTION         top

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

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