Run this code
#include #include #include 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() << '\n' << "thread 2 id: " << t2.get_id() << '\n'; std::swap(t1, t2); std::cout << "after std::swap(t1, t2):" << '\n' << "thread 1 id: " << t1.get_id() << '\n' << "thread 2 id: " << t2.get_id() << '\n'; t1.swap(t2); std::cout << "after t1.swap(t2):" << '\n' << "thread 1 id: " << t1.get_id() << '\n' << "thread 2 id: " << t2.get_id() << '\n'; t1.join(); t2.join(); }
Possible output:
thread 1 id: 140185268262656 thread 2 id: 140185259869952 after std::swap(t1, t2): thread 1 id: 140185259869952 thread 2 id: 140185268262656 after t1.swap(t2): thread 1 id: 140185268262656 thread 2 id: 140185259869952
