Hi, I'm trying to get SWIG to create a wrapper for some C code. I have some functions which take an int** (which points to an array of arrays, and they also take the dimensions as arguments). 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],[3,4]]) for the corresponding C function void my_c_function(int xsize, int ysize, int** aryary) Anyone have any idea how to help me? From various googling, I understand how to pass an array of ints, but passing arrays of arrays has me stumped. Thanks, -albert

Sorry I don't have a complete answer for you ... looks like this may take a bit of work. http://www.swig.org/Doc1.3/Typemaps.html#Typemaps_nn40 .... shows an example using Python. To call your function the way you want, looks like you'll need to write a typemap and/or helper functions to extract the Ruby array values and populate a C array with the correct type values. ruby.h has a bunch of conversion macros and prototypes that will help. Good luck!
