typedef struct _GstInterfaceClass {
  GTypeInterface parent;
                                                                                
  /* virtual functions */
  gboolean (* supported) (GstInterface *iface,
                          GType         iface_type);
                                                                                
  GST_CLASS_PADDING
} GstInterfaceClass;

Note the second argument in supported ().
