Constructor & Destructor Documentation

libcoyotl::mwc1038::mwc1038

(

)

The constructor initializes the prng seed from either the time or some stochastic source such as /dev/random or /dev/urandom.

(

uint32_t

seed

)

The constructor uses an explicit value for the seed.

Parameters:

seed	- Seed value used to "start" or seed the generator

[virtual]

Returns the next uint32_t in sequence.

Returns:

A pseudorandom uint32_t value

Implements libcoyotl::prng.

virtual void libcoyotl::mwc1038::init

(

uint32_t

seed

)

[virtual]

Resets the generator using the provided seed value.

Parameters:

seed	- Seed value used to "start" or seed the generator

Reimplemented from libcoyotl::prng.
