PMDASTORE(3)              Library Functions Manual              PMDASTORE(3)
       pmdaStore - store a value into a metric for a PMDA
       #include <pcp/pmapi.h>
       #include <pcp/pmda.h>
       int pmdaStore(pmResult *result, pmdaExt *pmda);
       cc ... -lpcp_pmda -lpcp
       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).
