|
The constructor initializes the prng seed from either the time or some stochastic source such as /dev/random or /dev/urandom.
| libcoyotl::mtwister::mtwister |
( |
uint32_t |
seed | ) |
|
The constructor uses an explicit value for the seed.
- Parameters
-
| seed | - Seed value used to "start" or seed the generator |
| uint32_t libcoyotl::mtwister::get_rand |
( |
| ) |
|
|
virtual |
Returns the next uint32_t in sequence.
- Returns
- A pseudorandom uint32_t value
Implements libcoyotl::prng.
| virtual void libcoyotl::mtwister::init |
( |
uint32_t |
seed | ) |
|
|
virtual |
Resets the generator using the provided seed value.
- Parameters
-
| seed | - Seed value used to "start" or seed the generator |
