NAME         top

       pmID_build, pmID_domain, pmID_cluster, pmID_item - helper methods
       for manipulating PMIDs

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       pmID pmID_build(unsigned int domain, unsigned int cluster,
       unsigned int item);
       unsigned int pmID_domain(pmID pmid);
       unsigned int pmID_cluster(pmID pmid);
       unsigned int pmID_item(pmID pmid);

DESCRIPTION         top

       Within the Performance Co-Pilot (PCP) each metric is assigned a
       unique Performance Metric Identifier (pmID).  Internally a pmID
       is constructed from 3 fields: the domain number (of the
       associated Performance Metrics Domain Agent, or PMDA), the
       cluster number and the item number (the last two are assigned by
       the PMDA).

       pmID_build constructs a pmID from domain, cluster and item.

       pmID_domain, pmID_cluster and pmID_item return the respective
       fields from pmid.
