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.
