Here is the caller graph for this function:

void rand_rng::simple_rng::seed_random	(	const int	seed,
		const unsigned	call_count = `0`
	)

Seeds the random pool.

Parameters:

	seed	The initial value for the random engine.
	call_count	Upon loading we need to restore the state at saving so set the number of times a random number is generated for replays the orginal value is required.
