Subject: [PATCH 5/8] Cygwin: pty: Discard input in from_master_nat pipe on signal as well.
Date: Sun, 13 Feb 2022 23:39:07 +0900 [thread overview]
Message-ID: <20220213143910.1947-6-takashi.yano@nifty.ne.jp> (raw)
In-Reply-To: <20220213143910.1947-1-takashi.yano@nifty.ne.jp>
- Currently, pty discards input only in from_master pipe on signal.
Due to this, if pty is started without pseudo console support and
start a non-cygwin process from cmd.exe, type adhead input is not
discarded on signals such as Ctrl-C. This patch fixes the issue.
