Subject: [PATCH v6 08/12] unix-socket: add backlog size option to unix_stream_listen()
Date: Mon, 15 Mar 2021 21:08:25 +0000 [thread overview]
Message-ID: <3b71f52d862832f3eb65d4041baac4c3a9f3e153.1615842510.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.766.v6.git.1615842509.gitgitgadget@gmail.com>
From: Jeff Hostetler <jeffhost@microsoft.com>
Update `unix_stream_listen()` to take an options structure to override
default behaviors. This commit includes the size of the `listen()` backlog.
