NAME         top

       pmdaStore - store a value into a metric for a PMDA

C SYNOPSIS         top

       #include <pcp/pmapi.h>
       #include <pcp/impl.h>
       #include <pcp/pmda.h>

DESCRIPTION         top

       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.

DIAGNOSTICS         top

       pmdaStore returns PM_ERR_PERMISSION to indicate that no metrics may
       be modified.

CAVEAT         top

       The PMDA must be using PMDA_PROTOCOL_2 or later, as specified in the
       call to pmdaDSO(3) or pmdaDaemon(3).
