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.

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
