Update.
2004-06-30 Ulrich Drepper <drepper@redhat.com> * include/net/if.h: Handle if_nameindex and if_freenameindex with libc_proto_hidden. * sysdeps/unix/sysv/linux/netlinkaccess.h: New file. * sysdeps/unix/sysv/linux/ifaddrs.c: Export netlink handling functions. * sysdeps/unix/sysv/linux/if_index.c (if_nameindex): Implement using netlink if possible. 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.
