This is really bad practice. It might accidentally work, but the
right way to do it is more like

Values[0] = Int32GetDatum(227);

or possibly Int64GetDatum if you're thinking of bigint rather than int4.

You're not being too clear about which "string type" you have in mind,
but if it's text, good practice would be

Values[1] = CStringGetTextDatum(char-*-ptr);
