Retrieve Table Length

[kfishermail]

I am monitoring signals emmitted by bluez(bluetooth)
A lot of the signals contain tables with no entrys
I need to know if a table is empty before trying to retrieve
it's contents.

I noticed there is a dbus function 'dbus_message_iter_get_element_count()' that
appears to do what I want, but I don't think it is implemented in ldbus.

questions:
What is the proper way to determine an empty table in a signal message?
Can the above function be added to ldbus?

Can the above function be added to ldbus?
