C++11 Thread 使用
基础用法
- 头文件
#include<thread>
- 函数
- 初始化
thread thread(<function_name>);
- 线程分离
thread.detach();
- 线程阻塞
thread.join()
- 线程取消
this_thread::yield();
- 线程休眠
this_thread::sleep_for(chrono::seconds(3));
代码
#include <iostream>
#include <thread>
#include <string>
using namespace std;
void proc()
{
cout << "Sub Thread proc" << endl;
}
void proc_1(int a)
{
cout << "Sub Thread proc 1 and a : " << a << endl;
}
void proc_2(int a, int b)
{
string msg = "Sub Thread proc 2 and a : " + to_string(a) + " b : " + to_string(b);
cout << msg << endl;
}
void proc_cancel()
{
cout << "Cancel current thread" << endl;
this_thread::yield();
}
void proc_wait_time()
{
cout << "wait 1s to exec" << endl;
return;
}
int main()
{
// thread initilization
thread thread1(proc);
thread thread2(proc_1, 10);
thread thread3(proc_2, 20, 30);
cout << "Main Thread" << endl;
// 在线程销毁前必须设置该线程是以何种方式等待线程的结束
// 是主线程等待子线程的返回,也就是 join
// 还是子线程运行结束后直接销毁资源,也就是 detach
# if 0
thread1.join();
thread2.join();
thread3.join();
#else
thread1.detach();
thread2.detach();
thread3.detach();
#endif
// get self id
thread::id thread_id = this_thread::get_id();
// sleep
this_thread::sleep_for(chrono::seconds(3));
// cancel thread
thread thread4(proc_cancel);
// thread detach
thread4.detach();
thread thread5(proc_wait_time);
// thread join
thread5.join();
return 0;
}
