Subject: [PATCH 2/5] Define _AT_NULL_PATHNAME_ALLOWED
Date: Wed, 12 Jul 2023 14:08:01 +0200 [thread overview]
Message-ID: <20230712120804.2992142-3-corinna-cygwin@cygwin.com> (raw)
In-Reply-To: <20230712120804.2992142-1-corinna-cygwin@cygwin.com>
From: Corinna Vinschen <corinna@vinschen.de>
Cygwin needs an internal flag to allow specifying an empty pathname
in utimesat (GLIBC extension). We define it in _default_fcntl.h to
make sure we never introduce a value collision accidentally.
While at it, define the values as 16 bit hex values.
