Detailed Description

Get Low level Hardware based noise supplied by the OS. NO SEED. NOT Deterministic (in theory) linux use "/dev/urandom" as a get_RandomSeed().

const void* Gray::cRandomOS::get_HeapPtr ( ) const

inlineoverridevirtualnoexcept

Get the top level (outermost, freeable) class pointer. I can delete get_HeapPtr().

Reimplemented from Gray::cHeapObject.

UINT Gray::cRandomOS::get_RandUns ( )

virtual

Reimplemented from Gray::cRandomBase.

HRESULT Gray::cRandomOS::GetNoise	(	void *	pData,
		size_t	iSize
	)

overridevirtual

fill array with random. return # filled.

Get the best source or random noise the system can supply. Make a random seed from the most random source we can find.

fill a buffer with random bytes of data. < 0 = error.

Reimplemented from Gray::cRandomBase.

HRESULT GRAYCALL Gray::cRandomOS::GetNoiseOS	(	void *	pData,
		size_t	iSize
	)

static

Try to use the OS supplied noise generator. It may not work.
