pmnameindomarchive(3)

NAME

   pmNameInDomArchive  - translate an instance identifier into an instance
   name

C SYNOPSIS

   #include <pcp/pmapi.h>

   int pmNameInDomArchive(pmInDom indom, int inst, char **name);

   cc ... -lpcp

DESCRIPTION

   Provided that the current Performance Metrics  Application  Programming
   Interface  (PMAPI)  context  is  associated with a set of archive logs,
   pmNameInDomArchive will scan the  union  of  all  the  instance  domain
   metadata  for the instance domain indom, locate the first instance with
   the internal instance identifier given by inst,  and  return  the  full
   external instance identification via name.

   This routine is a specialized version of the more general PMAPI routine
   pmNameInDom.

   The value for the instance domain indom is typically extracted  from  a
   pmDesc  structure, following a call to pmLookupDesc(3) for a particular
   performance metric.

   The  space  for  the  value  of  name  will  have  been  allocated   in
   pmNameInDomArchive  with malloc(3), and it is the responsibility of the
   caller to free(3) the space when it is no longer required.

   pmNameInDomArchive returns zero on success.

DIAGNOSTICS

   PM_ERR_NOTARCHIVE
          the  current  PMAPI  context  is  not  associated  with a set of
          archive logs

   PM_ERR_INDOM_LOG
          indom is not a defined instance domain identifier for the set of
          archive logs

   PM_ERR_INST_LOG
          the  instance  identifier  inst  is  not  known for the instance
          domain indom in the set of archive logs
