Re: [Swig-user] Help with returning pointers to structures

[Mohan P. <sur...@gm...>]

The problem was on this line
 res1 = SWIG_ConvertPtr(obj0, &argp1,SWIGTYPE_p_kdtree, 0 |  0 );

and changing this to

res1 = SWIG_ConvertPtr(obj0,SWIG_as_voidptrptr(&arg1), 0, 0);

solved the problem. I don't understand how structures are accessed. I am
unable to find a good tutorial on what needs to be done for passing
structures.

The easy solution for me is to use "void *" as that is sufficient for me.
But this may not be a satisfactory solution in a long time.
