Subject: [PATCH 3/5] python/machine: use connect-based interface for existing sockets
Date: Wed, 17 May 2023 12:34:04 -0400	[thread overview]
Message-ID: <20230517163406.2593480-4-jsnow@redhat.com> (raw)
In-Reply-To: <20230517163406.2593480-1-jsnow@redhat.com>

Instead of using accept() with sockets (which uses open_with_socket()),
use calls to connect() to utilize existing sockets instead. A benefit of
this is more robust error handling already present within the connect()
call that isn't present in open_with_socket().
