You noticed.. ;-)

Indeed, the Linux kernel uses this technique in some places to catch
type errors.

The attribute thoughts were to do with warning about errors in network
code that uses standard types and functions.  But thinking about it, to
avoid warnings you'd need as many changes in the application code as for
your struct wrappers.  (I.e., none if all you do is
`addr.sin_port = htons (port)' etc.; sometimes more).

Consider anything I said on this topic withdrawn, stomped upon,
dismissed, discarded etc.
