Subject: [PATCH 01/23] pipe.7: also mention writev(2) in atomicity section
Date: Sun,  8 Aug 2021 10:41:11 +0200	[thread overview]
Message-ID: <20210808084133.734274-2-alx.manpages@gmail.com> (raw)
In-Reply-To: <20210808084133.734274-1-alx.manpages@gmail.com>

From: наб <nabijaczleweli@nabijaczleweli.xyz>

writev(2) notes that buffers don't interleave with other process'
(a reasonable question to ask), but points to pipe(7) for an exception.
pipe(7) did /not/ mention "writev", "iov", "scat", or "gath", which are,
in order, reasonable search terms: this was confusing at best and
alarming at worst

By mentioning writev(2) in the heading, we clearly note that this sort
of interleaving behaviour matches write(2)'s and isn't a concern
