C SYNOPSIS

DESCRIPTION
As part of the Performance Metrics Domain Agent (PMDA) API
(see PMDA(3)), pmdaStore is the generic callback for stor
ing 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 met
rics to be altered by pmstore(1) is very application
dependent.
DIAGNOSTICS
pmdaStore returns EACCESS to indicate that no metrics may
be modified.
CAVEAT
The PMDA must be using PMDA_PROTOCOL_2 or later, as speci
fied in the call to pmdaDSO(3) or pmdaDaemon(3).
