Subject: [PATCH v2 10/25] Delete def_uiout
Date: Mon, 21 Mar 2016 15:26:00 -0000	[thread overview]
Message-ID: <1458573675-15478-11-git-send-email-palves@redhat.com> (raw)
In-Reply-To: <1458573675-15478-1-git-send-email-palves@redhat.com>

Currently current_uiout starts out pointing to def_uiout, a dummy
ui_out implementation.

I noticed that since we create a replacement uiout early on, as soon
as we create the interpreter, that we never actually use def_uiout.
So this patch removes it.

The proof that it works is that starting with current_uiout set to
NULL does not crash.
