Subject: [PATCH 01/16] vcs-svn: Eliminate global byte_buffer[] array
Date: Sun, 10 Oct 2010 21:37:10 -0500 [thread overview]
Message-ID: <20101011023710.GA1553@burratino> (raw)
In-Reply-To: <20101011023435.GA706@burratino>
The data stored in byte_buffer[] is always either discarded or
written to stdout immediately. No need for it to persist between
function calls.
