void seed();	(1)	(since C++11)
void seed( result_type value );	(2)	(since C++11)
template< class SeedSeq > void seed( SeedSeq& seq );	(3)	(since C++11)

Reinitializes the internal state of the underlying engine using a new seed value.

1) Seeds the underlying engine with the default seed value. Effectively calls e.seed(), where e is the underlying engine.

2) Seeds the underlying engine with the seed value value. Effectively calls e.seed(value), where e is the underlying engine.

3) Seeds the underlying engine with the seed sequence seq. Effectively calls e.seed(seq), where e is the underlying engine.

This overload participates in overload resolution only if SeedSeq satisfies the requirements of SeedSequence.

Parameters

value	-	seed value to use in the initialization of the internal state of the underlying engine
seq	-	seed sequence to use in the initialization of the internal state of the underlying engine

Exceptions

3) If SeedSeq is not std::seed_seq, throws the exceptions thrown by the seq.generate call.

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

LWG 2181	C++11	overload (3) would not throw even if the seq.generate call throws	propagates the exception
