求助:我的 dll 中的数组调用总是出错，请帮我看看啊，谢谢！

请教:
// iTween.cpp : 定义 DLL 应用程序的导出函数。

#ifdef ITWEEN_EXPORTS
#define DLL_API __declspec(dllexport)
#else
#define DLL_API __declspec(dllimport)
#endif

int groupID = 0xC154;
char dogOnlyId[30] = "314A990D1A6E4D0F";


extern "C" DLL_API int ReadGroupID()
{
return groupID;
}

extern "C" DLL_API void ReadDogOnlyId(char *getDogOnlyId)
{
getDogOnlyId = dogOnlyId;
}

编译为 iTween.dll


// Test1.cpp : 定义 DLL 应用程序的导出函数。
#ifdef TEST1_EXPORTS
#define DLL_API __declspec(dllexport)
#else
#define DLL_API __declspec(dllimport)
#endif


int groupID = 0xC153; //分组号
char dogOnlyId[64] = "314A990D1A60F";


extern "C" DLL_API int readNumber()
{
HINSTANCE hDllInst = LoadLibrary("iTween.dll");

typedef int (WINAPI *FunReadGroupID)();

typedef void (WINAPI *FunReadDogOnlyId)(char *);


FunReadGroupID MyReadGroupID = NULL; //函数别名
FunReadDogOnlyId MyReadDogOnlyId = NULL;

MyReadGroupID = (FunReadGroupID)GetProcAddress (hDllInst, "ReadGroupID");

MyReadDogOnlyId = (FunReadDogOnlyId)GetProcAddress (hDllInst, "ReadDogOnlyId");

if(MyReadGroupID)
{
groupID = MyReadGroupID();
}

if(MyReadDogOnlyId)
{
MyReadDogOnlyId(dogOnlyId);
}


FreeLibrary(hDllInst);
}


编译为 Test1.dll


现在情况是，我在别的程序调用 Test1.dll 的 readNumber()

当执行 MyReadDogOnlyId(dogOnlyId);

就出现错误。

Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.
This is usually of calling a function declared with one calling convention with a function
pointer declared with a different calling convention

我哪里错了啊？

谢谢!

调用约定不对....
