Parameters (none) Return value A value of type std::jthread::id identifying the thread associated with *this. If there is no thread associated, default constructed std::jthread::id is returned. Example // Run this code #include <iostream> #include <thread> #include <chrono> void foo() { std::this_thread::sleep_for(std::chrono::seconds(1)); } int main() { std::jthread t1(foo); std::jthread::id t1_id = t1.get_id(); std::jthread t2(foo); std::jthread::id t2_id = t2.get_id(); std::cout << "t1's id: " << t1_id << '\n'; std::cout << "t2's id: " << t2_id << '\n'; } Possible output: t1's id: 0x35a7210f t2's id: 0x35a311c4 See also id represents the id of a thread (public member class of std::thread) checks whether the thread is joinable, i.e. potentially running in parallel joinable context (public member function) http://cppreference.com 2022.07.31 std::jthread::get_id(3)
