[Swig-user] Re: double pointer problem

[Marcelo M. <mm...@ac...>]

Given that

int build(objid **pid)
{
 pid[0]->val = 10;
 pid[0]->wt =20;
 return 1;
}

is expecting an array ob aobjid, you need to provide
an array of pointer.

look at the carray.i and cpointer.i if you can get any solution
or ideas from them, and/or write a method that create the array 
for you, ie, something like

objid **new_objid_parray(int n) {
   objid **res = (objid **)malloc(sizeof(objid*)*(n+1));
   for (int i =0; i < n; ++i) {
	res[i] = malloc(sizeof(objid));
   }
   res[i] = 0;
   return res;
}

void delete_objid_parray(objid **parray) {
  for (...) ...
  free(parray);
}

in in python use it as

t1 = mymod.new_obid_parray(1)
mymod.build(t1)
...
delete_obid_parray(t1)


but again, take a look first at carray.i and cpointer.i for ready
to use solutions.
