std::seed_seq
std:: size_t size ( ) const noexcept ;
(since C++11)

Returns the size of the underlying seed sequence.

Return value

v  . size ( )

Complexity

Constant time.

Example

Run this code 
#include <iostream>
#include <random>
 
int main()
{
    std::seed_seq s1 = {-1, 0, 1};
    std::cout << s1.size() << '\n';
}

Output: 

3
