使用调试宏的简单示例代码

// testmac.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;

#define PRINTINFO PrintMacInfo(__FUNCTION__, __FILE__, __LINE__);

class A;
void TestFun(int a, int b);
void PrintMacInfo(char* szFunc, char* szFile, int nLine);

class A
{

	{
		PRINTINFO;
	}

	~A()
	{
		PRINTINFO;
	}

	void Fun(int a)
	{
		PRINTINFO;
		cout << "param = " << a << endl;
	}
};


int _tmain(int argc, _TCHAR* argv[])
{
	PRINTINFO;

	A a;
	a.Fun(12);
	TestFun(10, 20);
    
	return 0;
}

void TestFun(int a, int b)
{
	PRINTINFO;
	cout << "param:" << a << "\t" << b << endl;
}

void PrintMacInfo(char* szFunc, char* szFile, int nLine)
{
	cout << "---------- print info " << __DATE__ << " " << __TIME__ <<  "------------" << endl;

}
