Member Function Documentation

bool Random::fillRandom	(	void *	ptr,
		size_t	bytes
	)		const [virtual]

Fills the specified buffer with random data generated using the best quality random number generation facilities available.

Under Windows (including MinGW) CryptGenRandom is used, while under Unix-like operating systems /dev/urandom is used. If no special random number generation facility is detected the function falls back to use a MersenneTwister.

Returns:

This method returns false if the function had to fallback to MersenneTwister otherwise returns true.

void Random::fillRandomMersenneTwister	(	void *	ptr,
		size_t	bytes
	)		const

Fills the specified buffer with random data generated using a defMersienneTwister().

MersienneTwister produces high quality random number and can be much faster than fillRandom().
