I think that nearly all languages these day shave to take into account "what C does" and they need to have packing etc taken explicitly into account when they do syscalls etc. so I don't think that you will have too many problems and there should be some facility available to you to do the right packing if it's needed.
The C packing is done to maximise the efficiency of the structure given that particular platform. I don't think that packing it would be useful as the messages are never supposed to leave the machine, and if we pack netgraph messages, then where do we stop? Should we pack all ioctl structures too?
(sorry to make life more difficult for you but...)
No problem, I just wanted to make sure I wasn't missing something - I'm just writing a small program to create C structs and ML definitions at the moment, shouldn't be too bad.

BTW what IS OCaml? I've seen it mentionned a few times now..
A modern functional language - statically typed, generates pretty tight native code on a number of architectures. Extremely nice for speedy networking code without the hassle of memory leaks and overflows, or the portability and speed issues of Java.
