From 73377229bb33ab79682ce4b126a63602d13304ad Mon Sep 17 00:00:00 2001 From: Katerina Barone-Adesi Date: Thu, 21 Feb 2013 05:16:29 +0000 Subject: Added a ring buffer log target to store the last N log messages. The log target can be used via log alarms and show alarms. Why? This feature was proposed/requested at http://openbsc.osmocom.org/trac/wiki/Tasks/ErrorLogTarget All messages use the same amount of space, prioritizing simplicity. --- include/osmocom/core/loggingrb.h | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 include/osmocom/core/loggingrb.h (limited to 'include/osmocom/core/loggingrb.h') diff --git a/include/osmocom/core/loggingrb.h b/include/osmocom/core/loggingrb.h new file mode 100644 index 00000000..a6f377b1 --- /dev/null +++ b/include/osmocom/core/loggingrb.h @@ -0,0 +1,40 @@ +#ifndef _LOGGINGRB_H +#define _LOGGINGRB_H + +/* (C) 2012-2013 by Katerina Barone-Adesi + * All Rights Reserved + * + * 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 3 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.
