Note that strictly speaking, seeding srandom with time may not be exactly secure, but then, srandom's not a cryptographically secure RNG anyway. More to the point, the *only* time you want to use srandom() is when you want a reproducible set of pseudo-random numbers. If your original objective was to obtain random numbers, you should be reading bytes from /dev/random or similar. This email sent to site_archiver@lists.apple.com
