As part of the Performance Metrics Domain Agent (PMDA) API (see
PMDA(3)), pmdaStore is the generic callback for storing a value into
a metric. pmdaStore is usually a no-op as, by default, no metrics
can be altered. Also, the implementation of a store callback which
does permit metrics to be altered by pmstore(1) is very application
dependent.
pmdaStore returns PM_ERR_PERMISSION to indicate that no metrics may
be modified.
The PMDA must be using PMDA_PROTOCOL_2 or later, as specified in the
call to pmdaDSO(3) or pmdaDaemon(3).
