From 52835eb94a3e86ae0d050398ed139b6eecd0e3e1 Mon Sep 17 00:00:00 2001 From: Florian Forster Date: Sun, 5 Nov 2006 15:08:34 +0100 Subject: [PATCH] sensors plugin: Some code cleanup. Very long lines have been broken into several shorter ones. `strncmp' has been replaced with `strcmp' where reasonable. Variables have been renamed and all variable declarations have been moved to the top of the block, as required by ANSI C prior to C99. --- src/sensors.c | 160 +++++++++++++++++++++++++++----------------------- 1 file changed, 85 insertions(+), 75 deletions(-) diff --git a/src/sensors.c b/src/sensors.c index 9da22293..4dd826e2 100644 --- a/src/sensors.c +++ b/src/sensors.c @@ -52,7 +52,7 @@ #define BUFSIZE 512 -/** temperature and fan sensors */ +/* temperature and fan sensors */ static char *ds_def[] = { "DS:value:GAUGE:"COLLECTD_HEARTBEAT":U:U", @@ -69,11 +69,11 @@ static char *sensor_voltage_ds_def[] = static int sensor_voltage_ds_num = 1;
