By default, the fstream object just sets its "failbit," which you can check manually by calling my_stream.fail(). If you want anything particular to take place on failure to close a stream, you either have to call close manually, or you need a dedicated object whose destructor will deal with it. Alternatively, you can tell the fstream ahead of time that you want exceptions thrown if particular actions fail. There's a convention that destructors don't ever throw exceptions, though, so it would be unusual to request an exception when close() fails. -- http://mail.python.org/mailman/listinfo/python-list
