[Gumstix-users] i2c head file (i2c-dev.h ) question

[imato <coo...@gm...>]

Hi all,

I want to use my gumstix talk to an external i2c device (RTC). I searched
online and i found that i need to include an i2c head file (i2c-dev.h ) in
my program. I found an i2c-dev.h file from the internet. I post it here. can
anyone tell me if this is the correct head file? Do I just save the content
of this file to an i2c-dev.h file in my computer?

http://www.lm-sensors.org/browser/i2c-tools/trunk/include/linux/i2c-dev.h

meanwhile, I have read the i2c example from gumstix wiki page. It uses
#include <linux/i2c-dev.h>.
Why not is it #include <i2c-dev.h>

I am looking forward your help
Thanks in advance.
