Berrang=C3=A9 The object_ref/unref methods are intended for use with any subclass of the base Object. Using "Object *" in the signature is not adding any meaningful level of type safety, since callers simply use "OBJECT(ptr)" and this expands to an unchecked cast "(Object *)". By using "void *" we enable the object_unref() method to be used to provide support for g_autoptr() with any subclass. Signed-off-by: Daniel P.
