PMLOOKUPINDOMTEXT(3)

NAME
pmLookupInDomText - return text describing a performance metrics instance domain

C SYNOPSIS
#include <pcp/pmapi.h>

int pmLookupInDomText(pmInDom indom, int level, char **buffer);

cc ... -lpcp

DESCRIPTION
Retrieve descriptive text about the performance metrics instance domain identified by indom.

The value for the instance domain indom is typically extracted from a structure, following a call to pmLookupDesc(3) for a particular performance metric.

The argument level should be PM_TEXT_ONELINE for a one-line summary, else PM_TEXT_HELP for a more verbose description, suited to a help dialog.

The space pointed to by buffer will have been allocated in pmLookupInDomText with malloc(3), and it is the responsibility of the caller to free(3) the space when it is no longer required.

pmLookupInDomText returns zero on success.

DIAGNOSTICS

PM_ERR_NOTHOST
    For archives created with versions of PCP prior to 4.0, if the current PMAPI context is an archive log (help and one-line text was previously not maintained in the archive logs)
