 You must register the module with the preferences routine with -
 
        module_t *prefs_register_protocol(proto_id, void (*apply_cb)(void))
+       or
+       module_t *prefs_register_protocol_subtree(const char *subtree, int id,
+              void (*apply_cb)(void));
+
 
 Where: proto_id   - the value returned by "proto_register_protocol()" when
                     the protocol was registered.
        apply_cb   - Callback routine that is called when preferences are
                     applied. It may be NULL, which inhibits the callback.
+       subtree    - grouping preferences tree node name (several protocols can
+                    be grouped under one preferences subtree)
 
 Then you can register the fields that can be configured by the user with these
 routines -
