NAME

       pmSortInstances, pmSortHighResInstances - sort performance metric
       values on instance identifier

C SYNOPSIS

       #include <pcp/pmapi.h>

       void pmSortInstances(pmResult *result);
       int pmSortHighResInstances(pmHighResResult *result);

       cc ... -lpcp

DESCRIPTION

       The routine pmSortInstances may be used to guarantee that for
       each performance metric in the result from pmFetch(3) or
       pmFetchHighRes(3), the instances are in ascending instance
       identifier sequence.

       This is useful when computing rates from two consecutive samples.

SEE ALSO

       PMAPI(3), pmFetch(3) and pmFetchHighRes(3).
