# pmnameindomarchive(3)

translate an instance identifier into an instance name

Part of [pmNameInDomArchive(3)](/pmNameInDomArchive/3.md).

## 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)](/pmLookupDesc/3.md) for a particular performance metric.

The space for the value of *name* will have been allocated in **pmNameInDomArchive** with [**malloc**(3)](/malloc/3.md), and it is the responsibility of the caller to [**free**(3)](/free/3.md) 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
