伪函数与多线程

using namespace std;

//void operator ()() 对象名当作函数名，重载 ()
// () 仅仅适用于当前结构体对象
//不适合作为比线程参数，销毁太快

void main()
{
	myStruct go1;	
	thread t1(go1);
	myStruct go2;
	thread t2(go2);	//让每个对像名，变成函数名

	//myStruct():这个是构造函数 匿名对象。
	myStruct()();

	//不适合作为比线程参数，销毁太快
	thread t3(myStruct());

	t1.join();
	t2.join();
