NAME

6       Config::Generator::Random - Config::Generator pseudo-random support
7

DESCRIPTION

9       This module eases the generation of pseudo-random "data". The goal is
10       to be able to generate random but reproducible data, for instance to
11       smear times in crontabs.
12
13       The initial seed usually comes from a file named "random.bin" that can
14       be created with something like:
15
16         $ dd if=/dev/urandom of=random.bin bs=512 count=1
17
18       Then, modules can use the random_seed() function to make sure that what
19       they generate is different from what other modules generate.
20
21       Finally, modules can use the random_integer() function to generate
22       reproducible pseudo-random integers.
23

FUNCTIONS

25       This module provides the following functions (none of them being
26       exported by default):
27
28       random_init([PATH])
29           initialize the pseudo-random generator with the content of the
30           given file or by using a file named "random.bin" if it can be
31           located via the usual include path (the @IncPath variable of the
32           Config::Generator module)
33
34       random_integer(N, DATA...)
35           return a pseudo-random integer between 0 and N-1, using the given
36           DATA for additional seeding
37
38       random_seed(DATA)
39           add the given DATA to the initial seed used by the pseudo-random
40           generator
