[Swig-user] How to prevent allocation and wrapping of a return type

[Jimi D. <jd...@ac...>]

Hi,

I have created a typedef of a 64 bit integer that will be my return type 
called AIORET_TYPE.
ie:

typedef int64_t AIORET_TYPE.

I have a number of functions that return this AIORET_TYPE type. Hence I 
don't want to create custom signatures for all of these functions.


My problem is that SWIG believes that this is a structure, is allocating 
memory ( of size AIORET_TYPE ) to copy this value into , and it is 
returning as a PyObject *.

How can I get SWIG to ignore this type and realize that nothing needs to 
be allocated ?


I've tried adding

typedef int64_t AIORET_TYPE;

and

%inline %{
typedef int64_t AIORET_TYPE;
%}

but neither have worked for me and I still see this error message:


swig/python detected a memory leak of type 'AIORET_TYPE *', no 
destructor found.


This seems simple but I can't find a good place to start in the 
documentation.
