So essentially you are saying that it is impossible to completely defend against sloppy programming and lack of documentation. Or, to put it another way, if you make something foolproof, they just come up with a better fool. :-) > The point, again: *all* multithreaded code is susceptible to race > conditions and deadlocks. There is *no* way around this. Obviously. But my point is that you can hide a lot of the complexity that comes with multithreading, *if* you properly define the interfaces, and don't stray from the path. > Now, are you getting the point? :) Yes. We desperately need a comprehensive FG hacker's guide to the galaxy. :-) - -- Regards, "I RADIS, do you?" =Martin= http://www.iradis.org/ PGP: FE87448B DDF8 677C 9244 D119 4FE0 AE3A 37CF 3458 FE87 448B From: Martin van Beilen <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: [Flightgear-devel] New subsystem: FGEnvironment In-Reply-To: <[EMAIL PROTECTED]>; from [EMAIL PROTECTED] on Mon, Feb 25, 2002 at 05:07:16PM -0800 X-S-Issue: [EMAIL PROTECTED] 2002/02/27 01:34:27 2ed0948a567b8aeaac36e3a8338e87ea -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) iEYEARECAAYFAjx8KZsACgkQN880WP6HRIt/CwCfa/2C0NN+vWyjWW6/ySGccf5z 6ioAn0VfiySeXw6x1FmumRBABYrPNitL =Qx0v -----END PGP SIGNATURE----- _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
