NAME
       pmNameID - translate a PMID to a performance metric name

C SYNOPSIS
       #include <pcp/pmapi.h>

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

       cc ... -lpcp

DESCRIPTION
       Given  a  Performance  Metric ID (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.

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

       In the absence of errors, pmNameID returns zero.

DIAGNOSTICS
       PM_ERR_NOPMNS
	      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)).

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

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