Dear Friend

my program is


typedef std::vector<int> vec_name;

struct network
{
boost::variant<vec_name> net_id;
};

typedef std::vector<network>network_list;

// create the instance for vector

network_list net_list;

for(int i=0; i<net_list.size(); ++i)
{
unsigned char* query_str = net_list[0].net_id;
}

ERROR is
error: cannot convert ‘boost::variant<odtone::mih::null,
std::vector<std::basic_string<char> > >’ to ‘unsigned char*’ in assignment
