[Swig-user] return a value by reference

[Dagfinn A. <Dag...@fa...>]

Hi all,

=20

I am trying to return a value by using a reference, like this

=20

class Foo {

=20

 Int public bar(std::string &output, std:string input)=20

}

The swig module:

=20

%module FooTest

%{

=20

#include "Foo.h"

#include <string>

%}

  int  bar(std::string &output, std::string input);

};

The generated code for the string converts the string to a pointer, but
there is no way to get the return value?

How to create a swig module that allows me to get the return value from
output.
