Felipe Magno de Almeida 30df128be5 eldbus-cxx: Implementation of eldbus C++ API
Summary:
Applications can:

  void method_callback(void* data, const Eldbus_Service_Interface* iface,
                       const Eldbus_Message* message);
  struct { ... } data_struct;

  Eldbus_Method methods[] =
   {
     "method1", ELDBUS_ARGS("b", "bool"), ELDBUS_ARGS("b", "bool"), ELDBUS_METHOD_FLAG_HAS_DATA
     , (Eldbus_Method_Cb)&method_callback, &data_struct
   };

   And method_callback will be called with data parameter pointing to data_struct global object.

Also, Eldbus-cxx supports registering an interface passing a lambda or
function object as method. For example:

  edb::service_interface iface = edb::service_interface_register
    (c, path, interface
     , es::method("SendStringAndBool"
                  , [expected_string, expected_bool] (std::string const& n, bool b
                                                      , bool* out)
                  {
                    std::cout << "Running SendStringAndBool" << std::endl;
                    ck_assert(n == expected_string);
                    ck_assert(b == expected_bool);
                    *out = b;
                    return n;
                  }
                  , es::ins<std::string, bool>("string", "bool")
                  , es::outs<std::string, bool>("string", "bool")
                  )
    );

When a request for "SendStringAndBool" with the proper signature is
called, executes the lambda and replies with the return value and
its bool* out parameter value.
