c++线程的创建

c++ 11 线程编程实战

1，线程的创建

1.1 传入无参函数

//传入函数，创建线程
void  ThreadMain()
{//获取线程IDstd::thread::id  thisthreadId = std::this_thread::get_id();cout << "begin thread main" << endl;
}
int  main()
{thread  th1(ThreadMain);th1.join();
}

1.2 传入有参函数

//传入带参数的函数，创建线程
void  ThreadMainCanshu(int a, int b)
{//获取线程IDstd::thread::id  thisthreadId = std::this_thread::get_id();cout << "begin ThreadMainCanshu" << endl;cout << "a : " << a << endl;cout << "b : " << b << endl;
}
int  main()
{thread  th2(ThreadMainCanshu, 1, 2);th2.join();
}

1.3 传入类内部函数

//传入类成员函数创建线程
class  MyThread
{
public:void Main(){//获取线程IDstd::thread::id  thisthreadId = std::this_thread::get_id();cout << "My Thread Main" << endl;thread th1(&MyThread::thcanshu, this, 10, 20);th1.detach();Sleep(10);}void  thcanshu(int a,int b){cout << "MyThread : a " << a << " b " << b << endl;}
};
void  dealth1()
{MyThread  myth;thread  th3(&MyThread::thcanshu, &myth, 10, 20);th3.join();
}void  dealth2()
{MyThread  myth;myth.Main();
}
int  main()
{dealth1();dealth2();
}

1.4 lambda表达式

std::thread  my_thread([]{cout<<"my thread"<<endl;
}
);
my_thread.join();
