需要引用头文件:`thread` 【C++11线程标准库】
注意:编译时 g++ <filename.cpp> -o main -lpthread -std=c++11
如果不添加编译选项:`lpthread` 则会报错:`collect2: error: ld returned 1 exit status`
多线程代码实例
- #include <iostream>
- #include <thread>
-
- using namespace std;
-
- thread::id main_thread_id = this_thread::get_id(); //获取当前线程的句柄id
-
- void hello() //测试单线程
- {
- if (this_thread::get_id() == main_thread_id)
- {
- cout << "this is main thread" << endl;
- }
- else
- {
- cout << "this is not main thread" << endl;
- }
- }
- void p_thread(int n) //线程睡眠n s
- {
- this_thread::s
