I'm afraid I don't understand the fix... and how it seems to affect the historical behaviour of srand()/rand(). How does it address the understanding that if I use srand(28), I will get exactly the same sequence of numbers srand(28) produced yesterday, last week, last year? I have worked with programs that depend on exactly that behavior. That is, given the same input seed - I expect to see the same "random" sequence again. This requirement would seem to indicate that changing srand()/rand() isn't really possible... And, also, I believe, why random() was introduced... Please, oh please, don't change that behavior in srand()/rand(). - Dave Rivers - -- rivers@dignus.com Work: (919) 676-0847 Get your mainframe programming tools at http://www.dignus.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
