C synopsis
#include <pcp/pmapi.h>

int pmdaDesc(pmID pmid, pmDesc *desc, pmdaExt *pmda);
cc ... -lpcp_pmda -lpcp
Overview
pmdaDesc uses the standard PMDA(3) data structures to return the pmDesc description in desc for the metric identified by pmid.
Caveat
The PMDA must be using PMDA_INTERFACE_2 or later, as specified in the call to pmdaDSO(3) or pmdaDaemon(3).
Diagnostics
If the pmid does not correspond to any metric supported by this PMDA, pmdaDesc returns PM_ERR_PMID.
