Re: [Boost-users] boost::serialization - extra 6 bytes overhead question?

ok I have this working, however...

packet_base: 12
packet_ping: 44
0 1 0
0 0 1001 44 2 3 7 32 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0  
0 0 0 0 0 0 0
          ^ packet actually starts here(packet_length).

There are 6 extra bytes overhead I know that 1001 is my class version.  
What are 0, 1, 0, 0 and 0?

I need this info for writing packet de-serialization in other languages.

Thanks in advance.
