NAME

   pmdaStore - store a value into a metric for a PMDA

C SYNOPSIS

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

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

   cc ... -lpcp_pmda -lpcp

DESCRIPTION

   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

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

CAVEAT

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