Namespaces
namespace	syten
	Syten namespace.

namespace	syten::Random
	The random number generation engine generation subsystem.

Functions
void	syten::Random::disableReproducible ()
	Sets the global seed to zero, causing non-reproducible generation of random number engines by `genEngine()`. More...

Engine	syten::Random::genEngine ()
	Returns a random number generation engine. More...

Result	syten::Random::genValue ()
	Generates a single value from the internal LCG, mainly useful for debugging. More...

Result const &	syten::Random::getSeed ()
	Returns the seed used by the internal LCG. More...

Result	syten::Random::initReproducible (Result const seed_=0)
	Initialises the global generating random number engine. More...

bool	syten::Random::isReproducible ()
	Returns true if the global seed is non-zero and no threading is used. More...

Variables
std::linear_congruential_engine< Result, 6364136223846793005ULL, 1442695040888963407ULL, 18446744073709551615ULL >	syten::Random::engine {std::random_device()()}
	Engine used to generate seeds for genEngine() below. More...

std::mutex	syten::Random::mtx_engine
	Mutex protecting genEngine (and engine) below if seed is non-zero. More...

Result	syten::Random::seed {0}
	global seed, if zero, none was set and genEngine() is non-deterministic More...
