From b2a1e381d81666fa6f6cb3eea72b05fbdab279a9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Bernon?= Date: Tue, 25 Jan 2022 10:13:36 +0100 Subject: [PATCH] widl: Clarify declaration type names vs (reference) type names. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Declaration type names prefer unqualified names whereas reference type names prefer fully qualified names. This makes C++ code use fully qualified names when referencing a type, fixing cases where types from other namespaces are used. It also allows to skip the enum / struct / union type prefix in WinRT C++ code.
