* See #GCancellable::cancelled for details on how to use this.
*
+ * Since GLib 2.40, the lock protecting @cancellable is not held when
+ * @callback is invoked. This lifts a restriction in place for
+ * earlier GLib versions which now makes it easier to write cleanup
+ * code that unconditionally invokes e.g. g_cancellable_cancel().
+ *
* Returns: The id of the signal handler or 0 if @cancellable has already
* been cancelled.
