c++ - 是否有将 REFIID 转换为有用名称的操作系统功能？

Question

缺少手动编写函数将一些已知的 REFIID 转换为名称，例如:

if (riid == IID_IUnknown) return "IUnknown";
if (riid == IID_IShellBrowser) return "IShellBrowser";
...

是否有系统调用可以为众所周知的(甚至所有)REFIID 返回合理的调试字符串？

感谢您的回复。以下是我根据您的反馈得出的结论 - 非常感谢!

CString ToString(const GUID & guid)
{
    // could use StringFromIID() - but that requires managing an OLE string
    CString str;
    str.Format(_T("%08X-%04X-%04X-%02X%02X-%02X%02X%02X%02X%02X%02X"),
        guid.Data1,
        guid.Data2,
        guid.Data3,
        guid.Data4[0],
        guid.Data4[1],
        guid.Data4[2],
        guid.Data4[3],
        guid.Data4[4],
        guid.Data4[5],
        guid.Data4[6],
        guid.Data4[7]);
    return str;
}

CString GetNameOf(REFIID riid)
{
    CString name(ToString(riid));
    try
    {
        // attempt to lookup the interface name from the registry
        RegistryKey::OpenKey(HKEY_CLASSES_ROOT, "Interface", KEY_READ).OpenSubKey("{"+name+"}", KEY_READ).GetDefaultValue(name);
    }
    catch (...)
    {
        // use simple string representation if no registry entry found
    }
    return name;
}
