pmLookupText - return text describing a performance metric
Синопсис C (C Synopsis)
#include <pcp/pmapi.h>
int pmLookupText(pmID pmid, int level, char **buffer);
cc ... -lpcp
Описание (Description)
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.
