Iterate over QList entries, it's needed to call qlist_entry_obj() to retrieve the stored QObject. I'm not sure if it's ok to have this, because it's not as easy as qlist_iter() and the QListEntry data type is now exposed to the users, which means we have one more struct to be maintained when we have libqmp. Adding anyway, as it's more compact and people are asking for it. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
