使用Visual调试库检测内存泄露

#include <iostream>

using namespace std;

// 使用调试库

#define _CRTDBG_MAP_ALLOC

#include <cstdlib>

#include <crtdbg.h>

// 重定义new运算符

#ifdef _DEBUG

#ifndef DBG_NEW

#define DBG_NEW new (_NORMAL_BLOCK,__FILE__,__LINE__)

#define new DBG_NEW

#endif

class Simple{

public:

Simple()

{

m_pInt = new int();

}

virtual ~Simple()

{

delete m_pInt;

}

void setIntPtr(intinInt)

{

*m_pInt = inInt;

}

private:

int* m_pInt;

};

void dosomething(Simple*&outSimple)

{

outSimple = new Simple();

}

int _tmain(int argc,_TCHAR* argv[])

{

_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF |_CRTDBG_LEAK_CHECK_DF);

Simple* pSimple = new Simple();

// 这里导致内存泄露

dosomething(pSimple);

delete pSimple;

return 0;

}

该程序有两处内存泄露：

Detected memory leaks!
