How create a reply without dbus_message_new_method_return?

[Claudio Takahasi]

Hi folks,

I am trying create a reply message without use the function
"dbus_message_new_method_return".

I know that I can create the reply message when I receive the msg and
add the arguments
after. But this approach is a little bit "ugly". I want extract the
values required to create
the reply and create it after using the "dbus_message_new" function.

My client is receiving a timeout error. I don't know what is problem.
Could someone help me? The client and the server code are below.


Regards,
Claudio.
