[modifier] Exemple

#include <iostream>
#include <thread>
#include <chrono>
 
void foo()
{
    std::this_thread::sleep_for(std::chrono::seconds(1));
}
 
void bar()
{
    std::this_thread::sleep_for(std::chrono::seconds(1));
}
 
int main()
{
    std::thread t1(foo);
    std::thread t2(bar);
 
    std::cout << "thread 1 id: " << t1.get_id() << std::endl;
    std::cout << "thread 2 id: " << t2.get_id() << std::endl;
 
    std::swap(t1, t2);
 
    std::cout << "after std::swap(t1, t2):" << std::endl;
    std::cout << "thread 1 id: " << t1.get_id() << std::endl;
    std::cout << "thread 2 id: " << t2.get_id() << std::endl;
 
    t1.swap(t2);
 
    std::cout << "after t1.swap(t2):" << std::endl;
    std::cout << "thread 1 id: " << t1.get_id() << std::endl;
    std::cout << "thread 2 id: " << t2.get_id() << std::endl;
 
    t1.join();
    t2.join();
}

Résultat :

thread 1 id: 1892
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
thread 2 id: 2584
