+ *
+ * In other words, this function will convert a floating reference (if

+ *
+ * Typically you want to use g_object_ref_sink() in order to
+ * automatically do the correct thing with respect to floating or
+ * non-floating references, but there is one specific scenario where
+ * this function is helpful.
+ *
+ * The situation where this function is helpful is when creating an API
+ * that allows the user to provide a callback function that returns a
+ * GObject. We certainly want to allow the user the flexibility to
+ * return a non-floating reference from this callback (for the case
+ * where the object that is being returned already exists).
+ *
+ * At the same time, the API style of some popular GObject-based
+ * libraries (such as Gtk) make it likely that for newly-created GObject
+ * instances, the user can be saved some typing if they are allowed to
+ * return a floating reference.
+ *
+ * Using this function on the return value of the user's callback allows
+ * the user to do whichever is more convenient for them. The caller will
+ * alway receives exactly one full reference to the value: either the
+ * one that was returned in the first place, or a floating reference
+ * that has been converted to a full reference.
+ *
+ * This function has an odd interaction when combined with
+ * g_object_ref_sink() running at the same time in another thread on
+ * the same #GObject instance. If g_object_ref_sink() runs first then
+ * the result will be that the floating reference is converted to a hard
+ * reference. If g_object_take_ref() runs first then the result will be
+ * that the floating reference is converted to a hard reference and an
+ * additional reference on top of that one is added. It is best to avoid
+ * this situation.
+ *
+ * Since: 2.70
+ * Returns: (type GObject.Object) (transfer full): @object
