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).
