Fall back on ioctl method if necessary. * include/unistd.h: Declare __truncate. * sysdeps/generic/truncate.c: Also define __truncate. * sysdeps/mach/hurd/truncate.c: Likewise. * sysdeps/unix/common/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/truncate64.c: Use __truncate, not truncate. --- sysdeps/unix/sysv/linux/netlinkaccess.h | 62 +++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/netlinkaccess.h (limited to 'sysdeps/unix/sysv/linux/netlinkaccess.h') diff --git a/sysdeps/unix/sysv/linux/netlinkaccess.h b/sysdeps/unix/sysv/linux/netlinkaccess.h new file mode 100644 index 0000000000..6672e714ff --- /dev/null +++ b/sysdeps/unix/sysv/linux/netlinkaccess.h @@ -0,0 +1,62 @@ +/* Copyright (C) 2004 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.
