Subject: [PATCH v5 08/21] tools/libvchan: notify server when client is connected
Date: Tue, 28 Apr 2020 00:04:20 -0400	[thread overview]
Message-ID: <20200428040433.23504-9-jandryuk@gmail.com> (raw)
In-Reply-To: <20200428040433.23504-1-jandryuk@gmail.com>

From: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>

Let the server know when the client is connected. Otherwise server will
notice only when client send some data.
This change does not break existing clients, as libvchan user should
handle spurious notifications anyway (for example acknowledge of remote
side reading the data).
