[Gumstix-users] using returned values of i2c-io

[Sebastien S. <seb...@zh...>]

Howdy!

I tried to embed the 'i2c-io' program (with the 'execvp()' command) into 
a bigger C program which has to handle with network sockets and USARTS 
on the robostix. Actually I'm not sure, it's the best way to do... but 
it's currently the fastest ;-)

I can write to the registers without any problem... but I don't know how 
to read them and use the returned value. Is there some standard 
Linux-way to do that? Otherwise, where is the source of i2c-io, so that 
I can include it in my program and stop making nonsense by calling it as 
an external application.

Thanks, Sébastien
