My knowledge is creaky and old, and my typing is worse! So, I'm glad someone is awake with a sense of humor around here. I need good slap down.

How about this: calling srand without an expression causes it to use a default which my be /dev/urandom in a best case.

But you usually don't want to explicitly call srand unless you are going to supply your own seed EXPR. let rand do it for you!

update: I'm going to crawl back into my cubicle like bed and come back when I can actually read your question and respond more thoughtfully. You are obviously using rand and were just wondering what the seed was. on *nix, it will most likely be /dev/urandom. But if a security guy is asking and you need crypto level randomness then my over obvious post might have some mete of merit.
