std::jthread::swap(3) C++ Standard Libary std::jthread::swap(3) NAME std::jthread::swap - std::jthread::swap Synopsis void swap( std::jthread& other ) noexcept; (since C++20) Exchanges the underlying handles of two jthread objects. Parameters other - the jthread to swap with Return value (none) Example // Run this code #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::jthread t1(foo); std::jthread 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'; } 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 See also swap(std::jthread) specializes the std::swap algorithm (C++20) (function) http://cppreference.com 2022.07.31 std::jthread::swap(3)
