#include <chrono>

void foo()
{
    std::this_thread::sleep_for(std::chrono::seconds(1));
}

void bar()
{

    std::cout << "thread 2 id: " << t2.get_id() << std::endl;

    Résultat :

thread 2 id: 2584
after std::swap(t1, t2):
thread 1 id: 2584
thread 2 id: 1892
after t1.swap(t2):
thread 1 id: 1892
