From 21b304b46a347772c1338b22fba6a15291bb2945 Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Sun, 17 Apr 2016 12:08:49 +0200 Subject: ipcpd: initial IPC processes Basic functions for implementation of IPC processes, and implementation of core functions of the shim IPCP over UDP. Updates to the build system to compile these IPC processes, as well as some fixes in the irmd (rudimentary capturing exit signals) and some fixes in the library, mainly relating to the messaging. Basic implementation of creation / bootstrapping / deletion of the shim UDP. Placeholders for other functions. --- src/ipcpd/ipcp-data.h | 91 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 91 insertions(+) create mode 100644 src/ipcpd/ipcp-data.h (limited to 'src/ipcpd/ipcp-data.h') diff --git a/src/ipcpd/ipcp-data.h b/src/ipcpd/ipcp-data.h new file mode 100644 index 00000000..d51f3730 --- /dev/null +++ b/src/ipcpd/ipcp-data.h @@ -0,0 +1,91 @@ +/* + * Ouroboros - Copyright (C) 2016 + * + * Utitilies for building IPC processes + * + * Dimitri Staessens + * Sander Vrijders + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program 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.
