開啟CRT的記憶體檢測

#ifdef _DEBUG#define _CRTDBG_MAP_ALLOCinline void ENABLE_CRT_MEMORY_LEAK_CHECK() { _CrtSetDbgFlag( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF); }#else#define ENABLE_CRT_MEMORY_LEAK_CHECK() {}#endif

使用

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow){UNREFERENCED_PARAMETER(hPrevInstance);UNREFERENCED_PARAMETER(lpCmdLine);ENABLE_CRT_MEMORY_LEAK_CHECK();return 0;}

如果有記憶體流失, 在命令列裡會輸出類似以下的提示

Detected memory leaks!Dumping objects ->{130} normal block at 0x00563240, 8 bytes long. Data: <        > CD CD CD CD CD CD CD CD Object dump complete.
