2 seed - return a value that may be used to seed a pseudo-random generator
11 Generate a pseudo-random seed based on a collection of system and process
12 information. The seed() builtin function returns a value:
18 It should be pointed out that the information collected by seed
19 is almost certainly non-chaotic. This function is likely not
20 suitable for applications (such as cryptographic applications)
21 where the unpredictability of seeds is critical. For such critical
22 applications, LavaRnd should be used. See the URL:
24 http://www.LavaRnd.org/
26 for information about seeding a pseudo-random number generator
27 (such as rand() or random()) with the cryptographic hash of the
28 digitization of chaotic system.
30 Given the above warning, this builtin function produces a seed that is
31 suitable for most applications that desire a different pseudo-random
32 sequence each time they are run.
34 The return value of this builtin function should NOT be considered
35 a random or pseudo-random value. The return value should be used
36 as an argument to a seed function such as srand() or srandom().
