Mapping C long unsigned integer with swig for ruby

ruby-talk
1

Hi everyone

I want to now how can I indicate to swig to consider a n unsigned long long
function input/output parameter as a ruby BigNum object.

with python, we use the typemap to do the conversion.: for example

/* Convert from Python --> C */
%typemap(in) int {
    $1 = PyInt_AsLong($input);
}

/* Convert from C --> Python */
%typemap(out) int {
    $result = PyInt_FromLong($1);

is there something equivalent with ruby

thank you

Maybe:

/* Convert from Python --> C */
%typemap(in) int {

      $1 = ULL2NUM($input);

}

/* Convert from C --> Python */
%typemap(out) int {

      $result = NUM2ULL($1);
