Yes.  And you can, if you like, add access functions that check the type
member on every access.

In another organisation you can define all the separate structues (I'd
still use a common struct for the common elements rather than
duplicating the declarations) and then you put them all in a union for
those cases where you need a generic object.  I'm not sure which would
suit you better.
