Accessing lm-senors with Lazarus?
lazarus / 32-Linux

Hi all, I have been a Linux Admin for about 5 years, a Delphi
programmer for 15 years and a Lazarus user for about a year.  I am
very impressed with Lazarus, it allows me to port most of my software
to Linux, which is great!!  I would like to write some siftware which
will allow my server to e-mail me if various system values are
approaching/exceeding set levels (i.e. cpu temp, system temp etc).  Is
there any way that I can access the lm sensors data from Lazarus?
Thanks for any help.

Similar to most of the system info on linux, thermal info can be found
in the file system. Newer systems have all their thermal info in the
/sys/class/hwmon/hwmon[0-*] directory structure. Older systems where
using /sys/class/thermal/thermal_zone[0-*]. Some systems use both.
Docs can be found at:
http://www.kernel.org/doc/Documentation/hwmon/sysfs-interface and

You might choose any of the 3 methods mentioned in this link:
http://www.lm-sensors.org/browser/lm-
sensors/trunk/doc/developers/applications
Besides already mentioned sysfs, you might want to catch output of
sensors command line program. Otherwise you will have to make a Pascal
wrapper for the libsensors library (but beware of the library
license).

For making Pascal wrappers for C library you can take a look at this:
