Subject: [PATCH] Cygwin: console: Abort read() on SIGWINCH if SA_RESTART is not set.
Date: Sun, 14 Feb 2021 17:52:06 +0900	[thread overview]
Message-ID: <> (raw)

- Currently, console read() keeps reading after SIGWINCH is sent
  even if SA_RESTART flag is not set. With this patch, read()
  returns EINTR on SIGWINCH if SA_RESTART flag is not set.
