C++11创建线程的几种方式

普通方式

void thread_proc()
{
    cout << "thread id = " << this_thread::get_id() << endl;
}

void m1()
{
    thread td(thread_proc);
    td.join();
}

Lambda表达式

void m2()
{
    thread td([](int a, int b)
    {
        cout << a << "+" << b << "=" << a + b << endl;
    }, 1, 2);
    td.join();
}

仿函数

struct functor 
{
    void operator() (int a, int b) 
    {
        cout << a << "+" << b << "=" << a + b << endl;
    }
};

void m3()
{
    thread td(functor(), 3, 2);
    td.join();
}

绑定对象

class CItem
{
    int data_;
public:
    CItem(int data) : data_(data) 
    {
    }
    void member_func()
    {
        cout << "this->data_ = " << this->data_ << endl;
    }
};

void m4()
{
    CItem obj(10);
    thread td(bind(&CItem::member_func, &obj));
    td.join();
}

成员方法

void m5()
{
    CItem obj(10);
    thread td(&CItem::member_func, &obj);
    td.join();
}

Lambda表达式成员方法

void m6()
{
    CItem obj(10);
    thread td([&obj](){
        obj.member_func();
    });
    td.join();
}
