在本教程中,我们将讨论一个程序来理解c++中的线程get_id()函数。
函数 Thread get_id ()验证进程的当前状态,然后返回正在执行的当前线程的 id。这个函数不带任何参数。
#include <chrono>
#include <iostream>
#include <thread>
using namespace std;
//creating thread
void sleepThread(){
this_thread::sleep_for(chrono::seconds(1));
}
int main(){
thread thread1(sleepThread);
thread thread2(sleepThread);
thread::id t1_id = thread1.get_id();
thread::id t2_id = thread2.get_id();
cout << "ID associated with thread1= " << t1_id << endl;
cout << "ID associated with thread2= " << t2_id << endl;
thread1.join();
thread2.join();
return 0;
}输出结果ID associated with thread1= 135456142132844 ID associated with thread2= 135121414221716
