返回值为std::thread::id标识与*this...
参数
%280%29
返回值
类型值std::thread::id标识与*this如果没有与线程相关的线程，则默认构造std::thread::id会被归还。
例外

例
二次
#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();
}二次
可能的产出：
二次
t1's id: 0x35a7210f
t2's id: 0x35a311c4二次
另见
id | represents the id of a thread (public member class) |
