From cppreference.com
void seed( result_type value = default_seed );
|
(1) | (since C++11) |
template< class SeedSeq >
void seed( SeedSeq& seq );

(2) | (since C++11) |
Sets the state of the random-number engine.
1) Right after the state is set,
*this == std::linear_congruential_engine(value) is true.2) Right after the state is set,
*this == std::linear_congruential_engine(seq) is true.Parameters
| value | - | seed value to use to set the state |
| seq | - | seed sequence to use to set the state |
Exceptions
2) If
SeedSeq is not std::seed_seq, throws the exceptions thrown by the seq.generate call.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
