NAME

std::thread::get_id - std::thread::get_id

Synopsis

std::thread::id get_id() const noexcept; (since C++11)

Returns a value of std::thread::id identifying the thread associated with *this.

Parameters

(none)

Return value

A value of type std::thread::id identifying the thread associated with *this. If there is no thread associated, default constructed std::thread::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::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
