New Revision: 328044
URL: https://svnweb.freebsd.org/changeset/base/328044

Log:
  Fix bug: increment the value of pmcstat_npmcs instead of moving pointer
  to the next int position.
  
  Bug was introduced in r324959 ("Extract a set of pmcstat functions and
  interfaces to the new internal library -- libpmcstat.")
  
  This fixes pmcstat top mode (-T) operation.
  Example: pmcstat -n1 -S clock.hard -T
