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
particular 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
