From adc6766221327f99ab484d66f6f92050ec9e62d7 Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Tue, 21 Feb 2017 08:02:37 +0100 Subject: lib: Exchange protocol info during CACEP This exchanges a protocol name, a protocol version and concrete syntax for the protocol upon CACEP. For CDAP, only version 1 and GPB are supported. No lists for other supported versions or syntaxes are exchanged (but the proto file supports it). CACEP fails if there is a mismatch between the protocol names, version and syntax specified by the communicating parties. --- src/lib/pol/cacep_proto.c | 52 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 src/lib/pol/cacep_proto.c (limited to 'src/lib/pol/cacep_proto.c') diff --git a/src/lib/pol/cacep_proto.c b/src/lib/pol/cacep_proto.c new file mode 100644 index 00000000..9990a05a --- /dev/null +++ b/src/lib/pol/cacep_proto.c @@ -0,0 +1,52 @@ +/* + * Ouroboros - Copyright (C) 2016 - 2017 + * + * CACEP - Read/Write Protocol info + * + * Sander Vrijders + * Dimitri Staessens + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public License + * version 2.1 as published by the Free Software Foundation. + * + * This 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.
