How can i get values from net.connman.Manager.GetServices with dbus-glib

[Seungjae Lee]

Dear All.

I am trying to making a parser with dbus-glib library.

I met a problems during getting result from dbus_g_proxy_call().

According to connman interfacing document,
net.connman.Manager.GetServicesmethod is in "a(
oa{sv})" - please refer last  paste.

Now I am trying to read messages likes this.

 if (dbus_g_proxy_call (proxy, "GetServices",&error,
       G_TYPE_INVALID,
       dbus_g_type_get_map ("GHashTable",
        DBUS_TYPE_G_OBJECT_PATH,
        dbus_g_type_get_map("GHashTable", G_TYPE_STRING, G_TYPE_VARIANT)),
       &service_hash,
       G_TYPE_INVALID))

but. I met this messages in dbus_g_proxy_call().

Error getting Manager properties: [Expected D-BUS dict entry, got type code
'r']

actually 'r' means structure, I don't have any idea to get this result.

Is there any way can i get reply message at once?

please kindly help me.
