std::seed_seq:: param

From cppreference.com
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

#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
