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
