However, I object removal of srand. Game programmers need "the same random sequence" on occasion. There should be srand to get the same sequence for repeatable behaviors. rand()/srand() may be renamed to sys_rand()/sys_srand() (or whatever suitable name for them) in case user needs system random sequence for whatever reasons. I don't insist to keep system's rand/srand, though. Regards, -- Yasuo Ohgaki yohgaki@ohgaki.net
