As part of the Performance Metrics Domain Agent (PMDA) API (see
PMDA(3)), pmdaName is the generic callback for translating a pmid into
one or more dynamic metric names (nameset).
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), pmdaName is a
skeleton implementation that returns PM_ERR_NAME.
A PMDA that supports dynamic performance metrics will provide a private
callback that replaces pmdaName (by assignment to version.four.name of
the pmdaInterface structure) and implements the translation from a pmid
to a set of dynamic performance metric names returned via nameset. The
behaviour, return values and memory allocation rules for nameset are
the same as for pmNameAll(3).
pmdaName returns PM_ERR_PMID if the name is not recognized or cannot be
translated. otherwise the number of metric names found (most commonly
The PMDA must be using PMDA_PROTOCOL_4 or later, as specified in the
call to pmdaDSO(3) or pmdaDaemon(3).
