I am working with C and glib and haven't found this interface. I use 1.26 version.
https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/autotests/util/iwd.py?h=1.26#n1034
There is the same call at GetManagedObjects() in 1.26 but I cannot find an equivalent method in C.
But :
By calling Introspect() on interface org.freedesktop.DBus.Introspectable() (object iwd/connman/iwd) I have found that it replies me with an XML that have the "under nodes" at the end of it
So by iterating on it I will be able to get all the managed object from iwd.
Is this the only solution using C ?
