D-Bus low-lewel API - sending an array of structures

[Bogdan Lotko]

Hello,

Many thanks for your help. Everything works perfect now.
I was confused reading the Low-level API it was not obvious that the 
exact type signature shall be given.
What for is the "r" code then, and when is it used?

To your question: Actually the whole module is written using  dbus-glib 
binding. There are only some methods written using low-level API.
They give me more flexibility in addressing of different interfaces and 
objects in the receiver process.
The whole sender process is a legacy software running on older LINUX 
versions (SuSE 8.2 and SLES 10), so I am not sure if the gdbus would be 
the right solution.

Once more thank you  for your help,

with best regards,

Bogdan
