_CRTDBG_MAP_ALLOC_CRTDBG_MAP_ALLOC

在应用程序的调试版本中定义 _CRTDBG_MAP_ALLOC 标志时,堆函数的基础版本将直接映射到其调试版本。When the _CRTDBG_MAP_ALLOC flag is defined in the debug version of an application, the base version of the heap functions are directly mapped to their debug versions. 该标志在 Crtdbg.h 中用于执行映射。The flag is used in Crtdbg.h to do the mapping. 此标志仅当已在应用程序中定义 _DEBUG 标志时才可用。This flag is only available when the _DEBUG flag has been defined in the application.
