Subject: [PATCH 2/3] http: check curl_multi_remove_handle for errors
Date: Mon, 12 Sep 2016 22:42:48 +0000	[thread overview]
Message-ID: <20160912224249.2520-3-e@80x24.org> (raw)
In-Reply-To: <20160912224249.2520-1-e@80x24.org>

This should help us catch usage errors as well as consolidating
the number of #ifdefs in our code.
