I've read the article here on the ei and marshalling topic:
http://www.trapexit.org/How_to_use_ei_to_marshal_binary_terms_in_port_programs

I've got it working as posted. But now I want to pass an array to c. I assume it's best to pass it as a list. How to handle the c driver side to read in the elements of the list into a c array?

Can anyone help?

Thanks in advance

To help illustrate:

What I'd like to do is this
>port:start().

>port:price(1,2,0,100,100,0.05,1,0.3,50,3,[2.3,4,6],[1.1,1.4,2],1).

So it's a mix of ints and doubles. Also the list of doubles. I know I'd have to handle the case if my list of double looked like a erlang string.

Thanks to the article posted here I've got it working for the doubles and ints. Running into troubles trying to get it to see the list as an array...
