seed - return a value that may be used to seed a pseudo-random generator
SYNOPSIS
seed()
TYPES
return integer
DESCRIPTION
Generate a pseudo-random seed based on a collection of system and process
information. The seed() builtin function returns a value:
0 <= seed < 2^64
IMPORTANT WARNING:
It should be pointed out that the information collected by seed
is almost certainly non-chaotic. This function is likely not
suitable for applications (such as cryptographic applications)
where the unpredictability of seeds is critical. For such critical
applications, LavaRnd should be used. See the URL:
http://www.LavaRnd.org/
for information about seeding a pseudo-random number generator
(such as rand() or random()) with the cryptographic hash of the
digitization of chaotic system.
Given the above warning, this builtin function produces a seed that is
suitable for most applications that desire a different pseudo-random
sequence each time they are run.
The return value of this builtin function should NOT be considered
a random or pseudo-random value. The return value should be used
as an argument to a seed function such as srand() or srandom().
EXAMPLE
; print srand(seed())
RAND state
; print srandom(seed())
RAND state
LIMITS
none
