PMLOOKUPTEXT(3) 					     Library Functions Manual						   PMLOOKUPTEXT(3)

NAME
       pmLookupText - return text describing a performance metric

C SYNOPSIS
       #include <pcp/pmapi.h>

       int pmLookupText(pmID pmid, int level, char **buffer);

       cc ... -lpcp

DESCRIPTION
       Provided  the  source of metrics from the current Performance Metrics Application Programming Interface (PMAPI) context is a host, retrieve
       descriptive text about the performance metric identified by pmid.

       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 pmLookupText with malloc(3C), and it is the responsibility of the caller to
       free(3C) the space when it is no longer required.

       pmLookupText returns zero on success.

DIAGNOSTICS
       PM_ERR_NOTHOST
	      if the current PMAPI context is an archive log (help and one-line text is not maintained in the archive logs)
