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)
void seed( SeedSeq& seq );
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.[edit] 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
