Why have you declared an enum here? ^ (can't see why this is needed)


The point is, you have to somehow keep track of wheter the union
contains a struct A or a struct B.

Ah, I see. I understand now. Actually it won't be necessary since the structs themselves contain a 'type' enum


union {
struct A str_A;
struct B str_B;
} the_struct;
};
