May I recommend you try the python pmfg (pmFetchGroup) API instead
of the low level one?  It takes care of quite a bit of the hassle.
Based on src/pmclient/pmclient_fg.py , something like:

   class TotalRead():
         ...
         def connect(self):
             /* decode context type & parameter via pmGetOptions* */
             self.fg = pmapi.fetchgroup(....)
             self.pids = self.fg.extend_indom('proc.psinfo.pid')

         def execute(self):
             self.fg.fetch()
             for (pid, pidname, value) in self.pids():
                try:
                    print "PID %d value %d" % (pid, value())
                except:
                    pass


(This the proc.psinfo.pid metric is sort of a reflexive test only,
in that its metric value is exactly the instance-domain-instance code#.)
