Defined in header <experimental/random>
void reseed();	(1)	(library fundamentals TS v2)
void reseed(std::default_random_engine::result_type value);	(2)	(library fundamentals TS v2)

Reseeds the per-thread random number engine and any std::uniform_int_distribution instances used by randint.

1) Sets the per-thread engine to an unpredictable state.

2) Seeds the per-thread engine g as if by g.seed(value).

Parameters

value

-

value of the new seed

Remarks

Subsequent calls to randint do not depend on values produced by the per-thread engine prior to calling reseed.
