It appears to me that the proper GType that matches up with an Array of Object Paths is:
dbus_g_type_get_collection("GSList", DBUS_TYPE_G_OBJECT_PATH)
This returns a pointer to a singly-linked list (GSList), which one may iterate through using g_slist_foreach, which calls an iterator function for each Object Path in the list.
A gpointer passed to the iterator function contains the Device path: (e.g., /hci0/dev_00_00_00_00_00_00), and may be cast to a (const char *) for processing as a C/C++ string.
Do I have this right, or is there a better way to attack this?
