.TH PMLOOKUPINDOMARCHIVE 3 "PCP" "Performance Co-Pilot"
.SH NAME
\f3pmLookupInDomArchive\f1 \- translate an instance name into an instance identifier
.SH "C SYNOPSIS"
.ft 3
#include <pcp/pmapi.h>
.sp
int pmLookupInDomArchive(pmInDom \fIindom\fP, const char *\fIname\fP);

.SH DESCRIPTION
.de CW
.ie t \f(CW\\$1\f1\\$2
.el \fI\\$1\f1\\$2
..
Provided the current
Performance Metrics Application Programming Interface (PMAPI)
context is associated with an archive log,
.B pmLookupInDomArchive
will scan the union of all the instance domain metadata
for the instance domain
.IR indom ,
locate the first instance with the external identification given by
.IR name ,
and return the internal instance identifier.
.PP
This routine is a specialized version of the more general PMAPI
routine
.BR pmLookupInDom .
.PP
Only the leading
non-space characters of
.I name
will be used to identify the instance.
.PP
The value for the instance domain
.I indom
is typically extracted from a
.CW pmDesc
structure, following a call to
.BR pmLookupDesc (3)
for a particular performance metric.
.PP
.B pmLookupInDomArchive
will return a positive instance identifier on success.

.SH DIAGNOSTICS
.IP \f3PM_ERR_NOTARCHIVE\f1
the current PMAPI context is not associated with an archive log
.IP \f3PM_ERR_INDOM_LOG\f1
.I indom
is not a defined instance domain identifier for the archive log
.IP \f3PM_ERR_INST_LOG\f1
the external instance
.I name
is not known for the instance domain
.I indom
in the archive log
