From 57a58f592b67a0ebf482f06315b9c546590126bf Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Sun, 4 Oct 1998 04:33:56 +0000 Subject: more smbw cleanups. - cleaned up prototyping. Unfortunately we can't auto-prototype wrapped.c because it replaces system functions. - split stat functions into smbw_stat.c (This used to be commit 04e92e692e49234df6fbbfd07a33b315ed62f0de) --- source3/smbwrapper/smbw_stat.c | 179 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 179 insertions(+) create mode 100644 source3/smbwrapper/smbw_stat.c (limited to 'source3/smbwrapper/smbw_stat.c') diff --git a/source3/smbwrapper/smbw_stat.c b/source3/smbwrapper/smbw_stat.c new file mode 100644 index 0000000000..5ca71ee2ef --- /dev/null +++ b/source3/smbwrapper/smbw_stat.c @@ -0,0 +1,179 @@ +/* + Unix SMB/Netbios implementation. + Version 2.0 + SMB wrapper stat functions + Copyright (C) Andrew Tridgell 1998 + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
