This variant is a bit simpler:

	n = 0;
	pyargv[n++] = exename;
	pyargv[n++] = scriptname;
	for (i = 1; i < argc; i++) {
		if (i > _NUM_ARGS) {
			fprintf(stderr, "abort: too many arguments\n");
			return 255;
		}
		pyargv[n++] = argv[i];
	}

	Py_Initialize();
	ret = Py_Main(n, pyargv);
	Py_Finalize();
	return ret;
