       pmNameID - translate a PMID to a performance metric name


       #include <pcp/pmapi.h>

       int pmNameID(pmID pmid, char **name);

       cc ... -lpcp


       Given  a  Performance  Metric  Identifier  (PMID)  via  pmid,  pmNameID will determine the
       corresponding metric name, if any, in the  Performance  Metrics  Name  Space  (PMNS),  and
       return this via name.

       If  the PMNS contains multiple names associated with the requested PMID, one of these will
       be returned via name, but there is no way to determine which of the duplicate  names  this
       will be.  See pmNameAll(3) if all of the corresponding names are required.

       As of Version 3.10.3 of PCP, duplicate names for the same PMID are allowed in the PMNS, so
       using pmNameAll(3) is recommended over pmnameID.

       name is a null-byte terminated string, allocated by pmNameID using malloc(3) and it is the
       caller's responsibility to call free(3) to release the storage when the value is no longer

       In the absence of errors, pmNameID returns zero.


              Failed to access a PMNS for operation.  Note  that  if  the  application  hasn't  a
              priori called pmLoadNameSpace(3) and wants to use the distributed PMNS, then a call
              to pmNameID must be made after the creation of a context (see pmNewContext(3)).

              pmid does not correspond to a defined PMID in the PMNS.

              Other diagnostics are for protocol failures when accessing the distributed PMNS.
