RE: Re: comedi + two ni6070E

I have never used CVS and I dont'n how to compile it because it has not
scrpits to copile. ¿Any help please?

Does exist any function in kcomedilib to have the same results as
cfc_read_array_from_buffer? If I shouldn't use that in my code I would
like to change it.

Thanks again
