Subject: [PATCH 01/19] sha1write: make buffer const-correct
Date: Thu, 24 Oct 2013 13:59:49 -0400 [thread overview]
Message-ID: <20131024175949.GA24180@sigill.intra.peff.net> (raw)
In-Reply-To: <20131024175915.GA23398@sigill.intra.peff.net>
We are passed a "void *" and write it out without ever
touching it; let's indicate that by using "const".
