Re: Problems with dbus_connection_borrow_message

Before getting into specifics, did you see the bit in the documentation 
that points out that libdbus is a low-level library and is painful to 
use? You would probably be better off with GDBus (part of GLib) or 
QtDBus (part of Qt), which interoperate with libdbus and are a lot 
easier: in particular, they integrate nicely with the main-loop 
conventions of their respective frameworks.

These are low-level functions that you probably shouldn't be using, even 
if you are using libdbus. The usual way to receive signals via libdbus 
is to add a "filter function", then "dispatch" the connection by either 
hooking it up to a main loop or calling 
dbus_connection_read_write_dispatch().

Are you using the right interface name?

Are you using the right signal name?

Did you ask to receive the signals you wanted, by adding a match rule?
