Is there an effective way in C++ to retrieve full signature of a function at run-time?

I need this for logging purpose. I’m aware of macro like __FUNCTION__, but doesn’t serve the purpose as it just returns the function names. There could be many overloaded versions of same function, I want to log the full function signature. I’m looking for a solution that work correctly if even function signature is modified. The solution should always log the current function signature

void log(const char* const message)    
    {
        cout << message << endl;
    }

    void ABC(const int& number)
    {
        Log(???); // what should I pass to this function so full signature of the ABC function is logged??
    }

The Predefined Macros (C/C++) page on MSDN has a list of all the available macros. The one you are looking for is, likely, __FUNCSIG__.
