If you don't add the 'type' value to the structures, then it won't work properly in the union! It will refer to some other member.
I'm assuming that you misunderstood what I meant by 'tagged union'. It's the final data structure in my previous post, following the text which you quoted. In C, a tagged union is not a union; it is a struct containing a tag (or type) and a union.
