3.3 Instead of SWIG_GetPtr, a function of the following form is used:
int SWIG_ConvertPtr(ScriptObj *o, void **ptr, swig_type_info *ty);
int SWIG_ConvertPtr(ScriptObj *o, void **ptr, swig_type_info *ty, int flags);
Note: the function name may differ in certain implementations (read
the source). For example:
int SWIG_ConvertPtr(ScriptObj *o, void **ptr, SWIGTYPE_p_p_int);
int SWIG_ConvertPtr(ScriptObj *o, void **ptr, SWIGTYPE_p_p_int,0);
Passing a value of '0' for the type will accept any pointer. This
works kind of like 'void *'.

future expansion.
3.4. To create a pointer object, one uses a function similar to
ScriptObj *SWIG_NewPointer(void *ptr, swig_type_info *ty);
ScriptObj *SWIG_NewPointer(void *ptr, swig_type_info *ty, int flags);
It works in a similar manner:
p = SWIG_NewPointer(ptr, SWIGTYPE_p_p_int);
p = SWIG_NewPointer(ptr, SWIGTYPE_p_p_int, 0);
You will have to read the source to get the exact function name
