[C++ multithreading series] [4] Use the member function of the class as the thread startup function

#include<iostream>
#include<thread>
using namespace std;


class A
{
public:
	A(int a):_a(a){}
	// 需要设置为静态函数，在访问成员函数
	static void f(A &a) {
		a.f2();
	}
	void f2() {
		cout << _a << endl;
	}
private:
	int _a;
};


int main(int argc, int * argv[])
{
	A a(5);
	thread t(&A::f,std::ref(a));
	t.join();

	system("pause");
}

Thread start function:

1. Ordinary functions

2. Function object

3. static function in class

4. lambda expression

 

However, the function in the member variable cannot be used as the start function of the thread
