64位下TLS函数怎么声明？

今天写了一个TLS测试，在32位下通过，64位下不成功，所以64位下该怎么写TLS回调函数呢？代码如下：

 #pragma comment(linker,"/INCLUDE:__tls_used")
void NTAPI MY_TLS_CALLBACK(PVOID DllHandle, DWORD Reason, PVOID Reserved);

//TLS回调函数测试
void NTAPI MY_TLS_CALLBACK(PVOID DllHandle, DWORD Reason, PVOID Reserved)
{
    if (Reason == DLL_PROCESS_ATTACH)
    {
        MessageBox(NULL, L"TLSTest!", NULL, MB_OK);
    }
}

#pragma data_seg(".CRT$XLX")
PIMAGE_TLS_CALLBACK pTLS_CALLBACKs[] = { MY_TLS_CALLBACK,0 };
#pragma data_seg()

报错：dllmain.obj : error LNK2001: 无法解析的外部符号 __tls_used

tls_used这个在64位上名字有变化。

这个我找到方法了，如下

 #ifdef _WIN64
#pragma comment(linker,"/INCLUDE:_tls_used")
#else
#pragma comment(linker,"/INCLUDE:__tls_used")
#endif // _WIN64


void NTAPI MY_TLS_CALLBACK(PVOID DllHandle, DWORD Reason, PVOID Reserved);
//TLS回调函数测试
void NTAPI MY_TLS_CALLBACK(PVOID DllHandle, DWORD Reason, PVOID Reserved)
{
    if (Reason == DLL_PROCESS_ATTACH)
    {
        MessageBox(NULL, L"TLSTest!", NULL, MB_OK);
    }
}

extern "C"
#ifdef _WIN64
#pragma const_seg(".CRT$XLX")
const
#else
#pragma data_seg(".CRT$XLX")
#endif
PIMAGE_TLS_CALLBACK pTLS_CALLBACKs[] = { MY_TLS_CALLBACK,0 };
#pragma data_seg()
#pragma const_seg()
