From 19c6dfea6dab220161cc89bc7d22c322b4b2dea2 Mon Sep 17 00:00:00 2001 From: isiora Date: Thu, 15 Mar 2018 12:23:42 +0000 Subject: Added proxy mechanism. The mechanism is comparable to a remote call. Added sockets stub. git-svn-id: svn://svn.code.sf.net/p/chibios/svn/trunk@11769 110e8d01-0319-4d1e-a829-52ad28d1bb01 --- .../RT-SAMA5D2-XPLAINED-SEC/proxies/tssockstub.h | 388 +++++++++++++++++++++ 1 file changed, 388 insertions(+) create mode 100644 demos/ATSAMA5D2/RT-SAMA5D2-XPLAINED-SEC/proxies/tssockstub.h (limited to 'demos/ATSAMA5D2/RT-SAMA5D2-XPLAINED-SEC/proxies/tssockstub.h') diff --git a/demos/ATSAMA5D2/RT-SAMA5D2-XPLAINED-SEC/proxies/tssockstub.h b/demos/ATSAMA5D2/RT-SAMA5D2-XPLAINED-SEC/proxies/tssockstub.h new file mode 100644 index 000000000..e631eb4c8 --- /dev/null +++ b/demos/ATSAMA5D2/RT-SAMA5D2-XPLAINED-SEC/proxies/tssockstub.h @@ -0,0 +1,388 @@ +/* + ChibiOS - Copyright (C) 2006..2018 Giovanni Di Sirio. + + This file is part of ChibiOS. + + ChibiOS 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 3 of the License, or + (at your option) any later version. + + ChibiOS 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.
