From a55d09bb2d74944b7ea5a7e81b7d3e86bc04cd42 Mon Sep 17 00:00:00 2001 From: Tomas Bzatek Date: Fri, 19 Jan 2024 18:26:34 +0100 Subject: common: Logging rework Use common logging macros for a consistent output. A logging domain needs to be set in a Makefile first (the _LOG_DOMAIN define). Heavy debugging output is guarded by the __DEBUG_INTERNAL define and omitted by default. Logging severity is controlled by the TUXCMD_DEBUG env. var, typically set by the tuxcmd process itself. --- common/logutils.h | 55 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 common/logutils.h (limited to 'common/logutils.h') diff --git a/common/logutils.h b/common/logutils.h new file mode 100644 index 0000000..2e67f04 --- /dev/null +++ b/common/logutils.h @@ -0,0 +1,55 @@ +/* Tux Commander VFS: Logging utilities + * Copyright (C) 2023-2024 Tomas Bzatek + * Check for updates on tuxcmd.sourceforge.net + * + * 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.
