std::seed_seq

Member functions

seed_seq::seed_seq

seed_seq::generate

seed_seq::size

seed_seq::param

 

template< class OutputIt > void param( OutputIt dest ) const;		(since C++11)

Copies the stored seeds to the range beginning with dest. Equivalent to std::copy(v .begin(), v .end(), dest);.

If values of type result_type are not writable to dest, the program is ill-formed.

If OutputIt does not satisfy the requirements of LegacyOutputIterator, the behavior is undefined.

Parameters

dest

-

the beginning iterator of the output range

Exceptions

Only throws the exceptions thrown by the operations on dest.

Example

Run this code

#include <iostream>
#include <iterator>
#include <random>
 
int main()
{
    std::seed_seq s1 = {-1, 0, 1};
    s1.param(std::ostream_iterator<int>(std::cout, " "));
}

Output:

-1 0 1
