c++內存洩漏處理（積累）

c++內存洩漏處理（積累）

寫c++程序時，經常會出現內存洩漏的問題，這裡從網上找了一種很麻煩的方法：如果想找到每個cpp文件的內存洩漏，都必須在每個cpp加上如下代碼：

#include 
#ifdef _DEBUG
#define DEBUG_CLIENTBLOCK   new(_CLIENT_BLOCK, __FILE__, __LINE__)
#define new DEBUG_CLIENTBLOCK
#else
#define DEBUG_CLIENTBLOCK
#endif

下面給出一段測試的代碼

test.h

#include 

void funNew();

#include "text.h"

#include 
#ifdef _DEBUG
#define DEBUG_CLIENTBLOCK   new(_CLIENT_BLOCK, __FILE__, __LINE__)
#define new DEBUG_CLIENTBLOCK
#else
#define DEBUG_CLIENTBLOCK
#endif

void funNew()
{
	int *p = new int();
}

#include 
#include 
#include "text.h"

#include 
#ifdef _DEBUG
#define DEBUG_CLIENTBLOCK   new(_CLIENT_BLOCK, __FILE__, __LINE__)
#define new DEBUG_CLIENTBLOCK
#else
#define DEBUG_CLIENTBLOCK
#endif

int main()
{
	_CrtSetDbgFlag (_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);

	int* p = new int();
	funNew();
	//delete p;
	return 0;
}
