(static-only-routines): Add mknodat. * io/Versions [GLIBC_2.4]: Add mkdirat, mkfifoat, __xmknodat. * io/sys/stat.h: Declare mkditat, mknodat, mkfifoat, __xmknodat. Define mknodat inline function. * include/sys/stat.h: Add hidden proto for __xmknodat. * sysdeps/generic/mkdirat.c: New file. * sysdeps/generic/mkfifoat.c: New file. * sysdeps/generic/mknodat.c: New file. * sysdeps/generic/xmknodat.c: New file. * sysdeps/unix/mkfifoat.c: New file. * sysdeps/unix/sysv/linux/mkdirat.c: New file. * sysdeps/unix/sysv/linux/xmknodat.c: New file. * sysdeps/generic/xmknod.c: Add one more parameter check. --- sysdeps/generic/mkdirat.c | 58 ++++++++++++++++++++++++++++++++++++++++++ sysdeps/generic/mkfifoat.c | 60 +++++++++++++++++++++++++++++++++++++++++++ sysdeps/generic/mknodat.c | 60 +++++++++++++++++++++++++++++++++++++++++++ sysdeps/generic/xmknodat.c | 63 ++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 241 insertions(+) create mode 100644 sysdeps/generic/mkdirat.c create mode 100644 sysdeps/generic/mkfifoat.c create mode 100644 sysdeps/generic/mknodat.c create mode 100644 sysdeps/generic/xmknodat.c (limited to 'sysdeps/generic') diff --git a/sysdeps/generic/mkdirat.c b/sysdeps/generic/mkdirat.c new file mode 100644 index 0000000000..ccea3aa8d8 --- /dev/null +++ b/sysdeps/generic/mkdirat.c @@ -0,0 +1,58 @@ +/* Copyright (C) 1991, 1995, 1996, 1997, 2005 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.
