#include <chrono>
void foo()
{
std::this_thread::sleep_for(std::chrono::seconds(1));
}
int main()
{
std::thread t1(foo);
std::thread::id t1_id = t1.get_id();
std::thread t2(foo);
std::thread::id t2_id = t2.get_id();
std::cout << "t1's id: " << t1_id << '\n';
std::cout << "t2's id: " << t2_id << '\n';
t1.join();
t2.join();
}Possible output:
t1's id: 0x35a7210f t2's id: 0x35a311c4
