C SYNOPSIS

DESCRIPTION

       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.
