C++ 中的线程 get_id() 函数。
在该教程中,我们将讨论一个了解 C++ 中的线程 get_id() 函数的程序。
线程 get_id() 函数验证进程当前的状态,然后返回正在执行的当前线程的 ID。此函数不采用任何参数。
实例
#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
ID associated with thread1= 135456142132844 ID associated with thread2= 135121414221716
