std::integral_constant won't compile?

Question

I want to make integral constant from char* and \"kernel32.dll\", but failed always. The following are my failed attempts, anyone can show me the correct usage?

Answer 1

You may declare a static const char* and use it in std::integral_constant, something like:

static constexpr const char money[] = "money";

int main()
{
    typedef void(*function_t)(int);
    function_t ptrFunc =
        delegate
            ::adapter<
                &Class::print,
                std::integral_constant >::invoke_no_fwd;
    auto type = delegate::
        adapter<&Class::print, std::integral_constant>::invoke_no_fwd;
    ptrFunc(-42); // 0
    type(0); // 42

    return 0;
}

Live example

You may use something like in Aligning static string literals to allow to write the literal string in std::integral_constant with a Macro.
