Unfortunly this example does not handle bit and byte order. Take a look at Ada's representation clauses for such topics.
Erlang has support for byte endianness but not (it seems) bit endianness.
I'm currently kicking up a fuss about this on the erlang-questions list,
since while Erlang's bitwise big-endian layout works OK for network
protocols, it fails for typical little-endian C structures with bit
fields.
Thanks for the pointer to Ada.
Tony.
