Could you please point how the proposed change is architecture/endianness/ dependent? > implementation-independent, Could you please elaborate, what "implementation" you mean here? > so you can't just send raw complex data structures Do we need to serialize (in pre_save and then release in post_save) our state into a buffer and to write it as one piece using the existing macro? This looks ok, but how is this different from what we are doing? Regards, Roman.
