Description Marko Myllynen 2015-09-17 11:38:07 EDT
Description of problem:
The below is from pcp2graphite.py but would be needed in other Python applications as well:

    # Convert a python list of pmids (numbers) to a ctypes LP_c_uint (a C array of uints).
    def convert_pmids_to_ctypes(self, pmids):
        import ctypes
        from ctypes import c_uint
        pmidA = (c_uint * len(pmids))()
        for i,p in enumerate(pmids):
            pmidA[i] = c_uint(p)
        return pmidA

        pmid = self.context.pmLookupName(name)[0]

        # NB: we'd like to do: result = self.context.pmFetch(self.pmids)
        # But: pmFetch takes ctypes array-of-uint's, not a python list.  It needs to become polymorphic.
        result = self.context.pmFetch(self.convert_pmids_to_ctypes(self.pmids))
