C ++ 11 concurrency management of the Program 2 ------ threads started threads

In this section:

　　Start a thread

　　Each program will have at least one thread, main function is to perform the entrance, which we call the main thread, and the rest have their own sub-thread entry function, the main thread and the child threads to run simultaneously. Child thread starts when std :: thread object is created.

1. None None Return Value parameter function do child thread inlet:

void func()
{
    cout << "func" <<endl;
}

std::thread my_job(func);

2. Overload Class () operator as a child thread inlet:

class thread_test 
{
public:
    void oprator()() const
    {
        cout << "thread test" <<endl;
    }
};

thread_test t;
std::thread my_job(t);

 3. Use lamda expression as the child thread entrance:

std::thread my_job([]{
    cout << "lamda" <<endl;
});

4. Common parameters, as a function of inlet sub-thread

void func(int i)
{
    cout << "i = " << i << endl;
}

int count = 0;
std::thread my_job(func, count);

 The non-parametric class member functions as a sub-thread inlet

 

class thread_test 
{
public:
    void func()
    {
        cout << "thread_test func" << endl;
    }
};
thread_test t;
std::thread my_job(&thread_test::func, &t);

 6. The class has member functions as a reference sub-thread inlet

class thread_test 
{
public:
    void func(int i)
    {
        cout << "thread_test func i = " << i << endl;
    }
};
thread_test t;
int count = 100;
std::thread my_job(&thread_test::func, &t, count);
