PMLOOKUPTEXT(3)         Library Functions Manual         PMLOOKUPTEXT(3)

NAME         top

       pmLookupText - return text describing a performance metric

C SYNOPSIS         top

       #include <pcp/pmapi.h>

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

       cc ... -lpcp

DESCRIPTION         top

       Retrieve descriptive text about the performance metric identified
       by pmid.

       The argument level should be  either 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(3), and it is the responsibility of the
       caller to free(3) the space when it is no longer required.

       pmLookupText returns zero on success.
