Dear friends,

                  please see the bellow my code and tell me how to get out
this problem please.when I try to print values of
variant it's giving the error as:

std::ostream& operator<<(std::ostream&, const status_rsp&)’:
worked.cpp:33: error: ‘const struct status_rsp’ has no member named ‘os’
worked.cpp:33: error: ‘const class boost::variant<int,
