Ok. I think my confusion came from the fact that we have to tell ffi whether values are signed or unsigned. As far as I can tell, this would be only useful in order to sign- or zero-extend the result value, if it did. (The docs included with libffi-3.2.1.tar.gz don't seem to say anything about that, which would make us both wrong---this specific behavior is not documented at all. I may be missing a point; please correct me in that case.) A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
