Subject: [PATCH 03/11] sio: remove exceptions
Date: Fri, 30 Nov 2018 18:39:35 +0300	[thread overview]
Message-ID: <14e50e3a3872a1898d5df006fb61442c1ab2e556.1543590433.git.v.shpilevoy@tarantool.org> (raw)
In-Reply-To: <cover.1543590433.git.v.shpilevoy@tarantool.org>
In-Reply-To: <cover.1543590433.git.v.shpilevoy@tarantool.org>

To turn sio into C it should not have exceptions.
Replace them with diagnostics setting. In some cases
errors are not critical so several functions return
an error criticalness along with setting or not
setting diag.
