C++回调成员函数

有不少面试问非静态成员函数能不能用作回调，答案是：能！

#include "stdafx.h"
#include <iostream>

using namespace std;

class Test
{
public:
	void CallBack(char* args)
	{
		cout<<args<<endl;
	}
};

int _tmain(int argc, _TCHAR* argv[])
{
	typedef (Test::*lpCallBack)(char* args);

	//取得函数地址
	//VC8可能要改为lpCallBack func = (lpCallBack)&Test::CallBack
	lpCallBack func = (lpCallBack)Test::CallBack; 

    Test t, *lpTest;

    lpTest = &t;
	(lpTest->*func)("Hello World!"); //回调测试

	system("pause");
	return 0;
}
