Subject: SWIG and Arrays (of ints)

Hi all,

I'm trying to get SWIG to create a wrapper for some C code.
Specifically, there are several functions that take, as parameters, an
int* (they also take the length of the array).  I don't know how to do
the typemap for this - I want to be able to write

My_module.my_c_function([1,2,3])

for the corresponding C function

void my_c_function(int size, int* ary)

Additionally, one of the functions takes an integer array as a
parameter, and I'd like it instead to return an array in Ruby (full of
Nums).  I know how to get it to return the argument (instead of doing
the pointer passing thing), but then it just thinks I want to pass it
an integer instead of an array of integers.

Anyone have any idea how to help me? Everything I've seen pertains to
char** and I'm not sure how to convert it to work how I want with
int*.

TIA,

Kurt
