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.
