Member functions
linear_congruential_engine::seed
Generation
Characteristics
Non-member functions
(C++11)(C++11)(until C++20)
(C++11)(C++11)
void seed( result_type value = default_seed );
(1)
(since C++11)
template< class SeedSeq >
void seed( SeedSeq& seq );
(2)
(since C++11)
void seed( SeedSeq& seq );
Sets the state of the random-number engine.
[edit] Parameters
value
-
seed value to use to set the state
seq
-
seed sequence to use to set the state
[edit] Exceptions
[edit] Complexity
1) Same as std::linear_congruential_engine (value).
2) Same as std::linear_congruential_engine (seq).
Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 2181 | C++11 | overload (2) would not throw even if the seq.generate call throws
