NAME

       pmdaDaemon - initialize the PMDA to run as a daemon

C SYNOPSIS

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

       void pmdaDaemon(pmdaInterface *dispatch, int interface, char *name, int domain, char *logfile,
               char *helptext);

       cc ... -lpcp_pmda -lpcp

DESCRIPTION

       pmdaDaemon  initializes  the pmdaInterface structure to use the interface extensions assuming the PMDA(3)
       is to be run as a daemon.  The pmdaInterface structure is initialized with:

       name           The name of the agent.

       domain         The default domain number of the agent which uniquely identifies this PMDA from other run‐
                      ning PMDAs.  This may be subsequently changed by a command line  option  -d  (see  pmdaGe‐
                      tOpt(3)).

       logfile        The  default  path to the log file.  This may be replaced by the -l command line option if
                      using pmdaGetOpt.

       helptext       The default path to the help text (see pmdaText(3).  This may be replaced by the  -h  com‐
                      mand line option if using pmdaGetOpt(3).  If no help text is installed, or you are not us‐
                      ing pmdaText(3), then this should be set to NULL.

       The  callbacks are initialized to pmdaProfile(3), pmdaFetch(3), pmdaDesc(3), pmdaText(3), pmdaInstance(3)
       and pmdaStore(3).

DIAGNOSTICS

       Unable to allocate memory for pmdaExt structure
                      In addition, the dispatch->status field is set to a value less than zero.

       PMDA interface version interface not supported
                      The interface version is not supported by pmdaDaemon.

CAVEAT

       The PMDA must be using PMDA_INTERFACE_2 or later.
