       pmdaDSO - initialize the PMDA to run as a DSO


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

       int pmdaDSO(pmdaInterface *dispatch, int interface, char *name, char *helptext);

       cc ... -lpcp_pmda -lpcp


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

       name           The name of the agent.

       helptext       The default path to the help text (see pmdaText(3).  If  no  help  text  is
                      installed,  or  you  are  not using pmdaText(3), then this should be set to

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

       The  interface  structure also contains the domain of the PMDA(3), which is defined in the
       pmcd(1) configuration file. The domain is used  to  initialize  the  metric  and  instance
       descriptors (see pmdaInit(3)).


       Incompatible version of pmcd detected
                      When pmcd(1) creates the pmdaInterface structure, the dispatch.comm.version
                      field is set to  the  highest  protocol  that  pmcd(1)  understands.   This
                      message indicates that the pmcd(1) process does not understand the protocol
                      used by pmdaDSO.

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


       The PMDA must be using PMDA_INTERFACE_2 or later.
