From 09cb0345854d08112b0c4c3e64c916884d617033 Mon Sep 17 00:00:00 2001 From: itojun Date: Wed, 5 Jul 2000 02:13:17 +0000 Subject: add getifaddrs(3) from bsdi. this is a magic function which lets you grab interface addresses in a portable manner, without headache of SIOCGIFCONF or sysctl. it is in bsdi/openbsd/netbsd already. from kame tree (actually, mandatory for latest kame tree). --- include/ifaddrs.h | 56 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 include/ifaddrs.h (limited to 'include/ifaddrs.h') diff --git a/include/ifaddrs.h b/include/ifaddrs.h new file mode 100644 index 0000000..6ebf288 --- /dev/null +++ b/include/ifaddrs.h @@ -0,0 +1,56 @@ +/* $FreeBSD$ */ + +/* + * Copyright (c) 1995, 1999 + * Berkeley Software Design, Inc.
