WDK 新增的重载运算符

我正在"本机子系统"的WDK中构建一个简单的代码我有一个重载新建和删除运算符的库这是代码：

    #include<ntddk.h>
    #define HEAP_ZERO_MEMORY    0x00000008
    #define HEAP_GROWABLE       0x00000002
    typedef NTSTATUS
    (NTAPI * PRTL_HEAP_COMMIT_ROUTINE)(
        IN PVOID Base,
        IN OUT PVOID *CommitAddress,
        IN OUT PSIZE_T CommitSize
        );
    typedef struct _RTL_HEAP_PARAMETERS {
        ULONG Length;
        SIZE_T SegmentReserve;
        SIZE_T SegmentCommit;
        SIZE_T DeCommitFreeBlockThreshold;
        SIZE_T DeCommitTotalFreeThreshold;
        SIZE_T MaximumAllocationSize;
        SIZE_T VirtualMemoryThreshold;
        SIZE_T InitialCommit;
        SIZE_T InitialReserve;
        PRTL_HEAP_COMMIT_ROUTINE CommitRoutine;
        SIZE_T Reserved[ 2 ];
    } RTL_HEAP_PARAMETERS, *PRTL_HEAP_PARAMETERS;

    void*  operator new(size_t sz);
    void   operator delete(void* p);
    void* mg_malloc(unsigned int size);
    int mg_free(void *buffer);
    void InitAPSupportLibrary();
    void FinishAPSupportLibrary();
    extern "C"
    {
    PVOID RtlAllocateHeap(
            __in      PVOID HeapHandle,
            __in_opt  ULONG Flags,
            __in      SIZE_T Size
            );
        BOOLEAN RtlFreeHeap(
            __in      PVOID HeapHandle,
            __in_opt  ULONG Flags,
            __in      PVOID HeapBase
            );
    PVOID
    RtlCreateHeap(

      IN ULONG                Flags,
      IN PVOID                Base ,
      IN ULONG                Reserve ,
      IN ULONG                Commit,
      IN BOOLEAN              Lock ,
      IN PRTL_HEAP_PARAMETERS RtlHeapParams  );


        PVOID RtlDestroyHeap(
            __in  PVOID HeapHandle
            );
    }

和 cpp 文件代码：

    #include "main.h"
    PVOID mainHeapHandle = NULL;

    void InitAPSupportLibrary()
    {
        mainHeapHandle = RtlCreateHeap(HEAP_GROWABLE,NULL,0,0,NULL,0);
    }
    void FinishAPSupportLibrary()
    {
        if(mainHeapHandle) RtlDestroyHeap(mainHeapHandle);
    }

    void* mg_malloc(unsigned int size)
    {
        if(!mainHeapHandle) 
            InitAPSupportLibrary();
        void *buf  = RtlAllocateHeap(mainHeapHandle,HEAP_ZERO_MEMORY,size);
        return buf;
    }
    int mg_free(void *buffer)
    {
        if (!mainHeapHandle) return 0;
        return RtlFreeHeap(mainHeapHandle,0,buffer)?1:0;
    }
    void*  operator new(size_t sz)
    {
        void* p = (void*)mg_malloc(sz);
        return p;
    }
    void  operator delete(void* p)
    {
        mg_free(p);
    }

错误是： 错误 C2373："运算符新"：重定义;不同类型的修饰符 错误 C2373："运算符删除"：重定义;不同类型的修饰符
