PMDASTORE(3)            Library Functions Manual            PMDASTORE(3)

NAME         top

       pmdaStore - store a value into a metric for a PMDA

C SYNOPSIS         top

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

       int pmdaStore(pmResult *result, pmdaExt *pmda);

       cc ... -lpcp_pmda -lpcp

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).
