PMLOOKUPINDOMTEXT(3)      Library Functions Manual      PMLOOKUPINDOMTEXT(3)

NAME         top

       pmLookupInDomText  -  return  text  describing  a performance metrics
       instance domain

C SYNOPSIS         top

       #include <pcp/pmapi.h>

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

       cc ... -lpcp

DESCRIPTION         top

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

       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 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

       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.
