From dc974da36d3f296eb33395633fd9f640eee3a239 Mon Sep 17 00:00:00 2001
From: csapuntz <csapuntz@openbsd.org>
Date: Wed, 19 Apr 2000 08:34:50 +0000
Subject: [PATCH] Change struct file interface methods read and write to pass
 file offset in and out.

Make pread/pwrite in netbsd & linux thread safe - which is the whole point
anyway.
