From c5a61e5a3c68144a421117916aef04f2c0fab84b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Mon, 31 Aug 2020 17:07:23 -0400 Subject: qom: make object_ref/unref use a void * instead of Object *. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
