From: Jinoh Kang Subject: [PATCH v2 2/2] server: Allow creating named pipes using \Device\NamedPipe\ as RootDirectory. Message-Id: Date: Thu, 25 Nov 2021 23:00:43 +0900 In-Reply-To: <9e9b0083-d6d3-6dd6-f030-0a5977015057@gmail.com> References: <9e9b0083-d6d3-6dd6-f030-0a5977015057@gmail.com> Separate the named pipe root directory from the named pipe device file. Open the root directory instead of the device file if the path ends with backslash.
