From 905ae44c77a4b899100de99360823a586e095622 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Sat, 11 Apr 2020 17:07:11 -0300 Subject: linux: Move posix dir implementations to Linux This generic implementation already expects a getdents API which is Linux specific. It also allows simplify it by assuming _DIRENT_HAVE_D_RECLEN and _DIRENT_HAVE_D_OFF support. The readdir are also expanded on each required implementation, futher fixes and improvements will make parametrize the implementation more complex. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for all affected ABIs. --- sysdeps/unix/sysv/linux/seekdir.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/seekdir.c (limited to 'sysdeps/unix/sysv/linux/seekdir.c') diff --git a/sysdeps/unix/sysv/linux/seekdir.c b/sysdeps/unix/sysv/linux/seekdir.c new file mode 100644 index 0000000..3c30520 --- /dev/null +++ b/sysdeps/unix/sysv/linux/seekdir.c @@ -0,0 +1,35 @@ +/* Copyright (C) 1991-2020 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library 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.
