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 an archive log,
       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 particu-
       lar performance metric.

       The space for the value of name will have been allocated in pmNameInDomArchive with malloc(3C), and it is the responsibility of the  caller
       to free(3C) 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 an archive log

       PM_ERR_INDOM_LOG
	      indom is not a defined instance domain identifier for the archive log

       PM_ERR_INST_LOG
	      the instance identifier inst is not known for the instance domain indom in the archive log
