pmNameInDomArchive - translate an instance identifier into an instance
name
#include <pcp/pmapi.h>
int pmNameInDomArchive(pmInDom
indom, int
inst, char

name);
cc ... -lpcp
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.
