From fc550f34ea40aa853250faf48cf14487581ac4b0 Mon Sep 17 00:00:00 2001 From: kan Date: Thu, 5 Apr 2007 22:02:39 +0000 Subject: Add trivial MI memset function implementation. GCC mandates the existence of this function as a linkable symbol in standalone configurations and existing inline memcpy from libkern.h fails this requirement. --- sys/libkern/memset.c | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 sys/libkern/memset.c (limited to 'sys/libkern') diff --git a/sys/libkern/memset.c b/sys/libkern/memset.c new file mode 100644 index 0000000..bbbbf30 --- /dev/null +++ b/sys/libkern/memset.c @@ -0,0 +1,37 @@ +/*- + * Copyright (C) 1992-2007 The FreeBSD Project.
