From 8cf1f2a33575f93a2a1411591dea02dadfff25a0 Mon Sep 17 00:00:00 2001 From: Thorsten Lockert Date: Thu, 14 Dec 1995 06:52:55 +0000 Subject: Kerberos IV code, based on a merge of fixed code from KTH and original 4.4BSD Lite code (international edition). Provides all functionality from the original 4.4BSD code plus standard Kerberos elements that were omitted in the 4.4BSD code. --- kerberosIV/krb/lsb_addr_comp.h | 54 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 kerberosIV/krb/lsb_addr_comp.h (limited to 'kerberosIV/krb/lsb_addr_comp.h') diff --git a/kerberosIV/krb/lsb_addr_comp.h b/kerberosIV/krb/lsb_addr_comp.h new file mode 100644 index 00000000000..75a517de9cb --- /dev/null +++ b/kerberosIV/krb/lsb_addr_comp.h @@ -0,0 +1,54 @@ +/* + * $Source: /cvs/OpenBSD/src/kerberosIV/krb/Attic/lsb_addr_comp.h,v $ + */ + +/* + * Copyright 1987, 1988 by the Student Information Processing Board + * of the Massachusetts Institute of Technology + * + * Permission to use, copy, modify, and distribute this software + * and its documentation for any purpose and without fee is + * hereby granted, provided that the above copyright notice + * appear in all copies and that both that copyright notice and + * this permission notice appear in supporting documentation, + * and that the names of M.I.T. and the M.I.T.
