Subject: [Qemu-devel] [PATCH v6 10/10] qemu-io: use no_argument/required_argument constants
Date: Mon, 15 Feb 2016 14:33:41 +0000	[thread overview]
Message-ID: <1455546821-6671-11-git-send-email-berrange@redhat.com> (raw)
In-Reply-To: <1455546821-6671-1-git-send-email-berrange@redhat.com>

When declaring the 'struct option' array, use the standard
constants no_argument/required_argument, instead of magic
values 0 and 1.
