If you clear errno, anyway, you can also drop the set_errno call, and zero-initialize errno before each call. The point of set_errno would be that you have the choice of *not* calling it, i.e. passing into the function the errno value that was there before you made the API call. If you fill something else into errno always, the application has no way of not modifying errno before the API call. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1798> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
