[Swig-user] PERL and C int pointer to pointer - Been on this several hours trying to figure out this (int **)

[Jay S <mys...@ya...>]

Here’s an example.1.  Getting the len parameter doesn’t seem to be a problem - comes out okay.2.       Could someoneplease  shine some light on what is the right way of getting the **arrout parameter back to perl? This is how I’m sending it in and it appears to work with c..Just don’t know how to get it out.3.       I have a typemap like this: TYPEMAP:%array_functions(int,intArray);%pointer_functions(int, intp); %typemap(in) int ** (int* intpref) {          SV* tempsv;     if (!SvROK($input)) croak("expected a reference\n");          tempsv = SvRV($input);     intpref = SvIV (tempsv);          $1 = &intpref;}%typemap(out) (int **arrayin,  int *OUTPUT) { }  PERL$a2 = example::new_intp();(@retarr, @retarr2)= example::return_array_int(\\$a1);  C void return_array_int(int **arrout, int *len){     int i=0;     *arrout = (int *)malloc(4 * sizeof(int));     *len=4;     for(i=0;i<4;i++) {          
 *(*arrout+i)=7-i;     }}
