Yes, that slightly improves ABI flexibility, though the fact that callers can still access fields limits that. An alternative is to make the only member `char opaque[16]` (IIRC some locale-related thing in glibc does this, also I think libpng went through a transition of some sort related to this?), but calculating the size can be difficult outside of trivial cases since you can't use sizeof/offsetof. |
