C++ 如何在运行时检查Win API函数支持？

如何在运行时检查函数GetSystemTimePreciseSFileTime是否受运行时支持？

使用著名的查找函数的存在性，如下所示

typedef void (WINAPI *FuncT) (LPFILETIME lpSystemTimeAsFileTime);

HINSTANCE hDLL = LoadLibrary(L"Kernel32.dll");
FuncT GetSystemTimePreciseAsFileTime = (Func) GetProcAddress((HMODULE)hDLL, L"GetSystemTimePreciseAsFileTime");

if (GetSystemTimePreciseAsFileTime)
{
   // function is exposed by the DLL, now it can be called
   GetSystemTimePreciseAsFileTime(...);
}

我必须将WINAPI调用签名移动到括号WINAPI*FuncT中才能使VS12高兴。我必须将WINAPI调用签名移动到括号WINAPI*FuncT中才能使VS12高兴。
