怎样检查你的代码有没有内存泄露呢? 需要在前面加上这些代码:
#ifdef _DEBUG
#define DEBUG_CLIENTBLOCK new( _CLIENT_BLOCK, __FILE__, __LINE__)
#else
#define DEBUG_CLIENTBLOCK
#endif
#define _CRTDBG_MAP_ALLOC
#include
#include
#include
#include
#ifdef _DEBUG
#define new DEBUG_CLIENTBLOCK
#endif
然后在要检测的代码前面加上:
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
在后面加上:
_CrtDumpMemoryLeaks();
如:
#ifdef _DEBUG
#define DEBUG_CLIENTBLOCK new( _CLIENT_BLOCK, __FILE__, __LINE__)
#else
#define DEBUG_CLIENTBLOCK
#endif
#define _CRTDBG_MAP_ALLOC
#include
#include
#include
#include
#ifdef _DEBUG
#define new DEBUG_CLIENTBLOCK
#endif
int main()
{
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
int *p;
p = new int;
_CrtDumpMemoryLeaks();
return 0;
}
然后按F5进行调试,会发现输出框中显示:
Detected memory leaks!
