Detailed Description

A multiply with carry psudeorandom number generator, as suggested by George Marsaglia.


Constructor & Destructor Documentation

libcoyotl::mwc256::mwc256  ) 
 

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

libcoyotl::mwc256::mwc256 uint32_t  seed  ) 
 

The constructor uses an explicit value for the seed.

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


Member Function Documentation

virtual uint32_t libcoyotl::mwc256::get_rand  )  [virtual]
 

Returns the next uint32_t in sequence.

Returns:
A pseudorandom uint32_t value

Implements libcoyotl::prng.

virtual void libcoyotl::mwc256::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.
