C SYNOPSIS#include <pcp/pmapi.h>

DESCRIPTIONAs part of the Performance Metrics Domain Agent (PMDA) API (see PMDA(3)), pmdaPMID is the generic callback for translating a dynamic metric name into a PMID (pmid).
Because implementing dynamic performance metrics requires specific PMDA support, and the facility is an optional component of a PMDA (most PMDAs do not support dynamic performance metrics), pmdaPMID is a skeleton implementation that returns PM_ERR_NAME.
A PMDA that supports dynamic performance metrics will provide a private callback that replaces pmdaPMID (by assignment to version.four.pmid of the pmdaInterface structure) and implements the translation from a dynamic performance metric name into the associated pmid.
