NAME
       pmSortInstances - sort performance metric values on instance identifier

C SYNOPSIS
       #include <pcp/pmapi.h>

       void pmSortInstances(pmResult *result);

       cc ... -lpcp

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

       This is most useful when trying to compute rates from two consecutive pmFetch(3) results.

SEE ALSO
       PMAPI(3) and pmFetch(3).

DIAGNOSTICS
       None.
