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.

I am writing a packet base class that can be serialized. The class so far looks like:

    class packet_base
    {
        using namespace boost;
        
        public:
            packet_base();
            ~packet_base();

            friend class boost::serialization::access;
            template <typename Archive>
            void serialize(Archive & ar, const unsigned int version)
            {
                ar & m_length;
ar & m_type;
ar & m_method;
            }

        private:
        
            uint16_t m_length;
    uint16_t m_type;
    uint16_t m_method;
    };

The question now is how can I derive class A from packet_base and have both packet_base and A's variables serialized? Obviously base_class needs to be archived first so it's variables are at the front of the buffer.

Thanks in advance.
