Subject: [PATCH 4/6] strbuf_readlink: use ssize_t
Date: Tue, 24 Jul 2018 06:51:25 -0400	[thread overview]
Message-ID: <20180724105125.GD17165@sigill.intra.peff.net> (raw)
In-Reply-To: <20180724104852.GA14638@sigill.intra.peff.net>

The return type of readlink() is ssize_t, not int. This
probably doesn't matter in practice, as it would require a
2GB symlink destination, but it doesn't hurt to be careful.
