重載new運算符與WDK

我建立一個簡單的代碼在WDK在「本地子系統」我有超載新圖書館和刪除操作這裏是代碼：重載new運算符與WDK



    #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文件代碼：



    #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); 
    }

和錯誤是：錯誤C2373： '運算新'：重新定義;不同類型修飾符錯誤C2373：'operator delete'：重新定義;不同類型修飾符

感謝您的幫助

如果你看看編譯器的<new>頭，用於operator delete聲明如下：

void __CRTDECL operator delete(void *) _THROW0();

如果宏__CRTDECL擴展到比沒有其他東西（但也許__cdecl），你可能與你的聲明不匹配。

與operator new相似。

感謝您的回覆，但我正在尋找另一種解決方案。不使用這些調用約定 – native99

問題是，有些代碼顯然看到''中的運算符和代碼中的運算符。編譯器不喜歡它們在調用約定時有所不同，因爲它不知道如何調用它們。 –
