[Boost-users] Boost Python: Howto wrap "out" arguments of a methode

4 Jun 2007

      How to wrap methode Get with Boost.Python?

      class MyClass {
      public:
          MyClass();

          void GetX(double &pos_x);
[...]

I'v tried it with:

          .def(
              "GetX"
              , &::MyClass::GetX
              , bp::arg("")
              , bp::return_value_policy<bp::return_arg<1>() >()

But when I try it in python:

Boost.Python.ArgumentError: Python argument types in
      MyClass.GetX(MyClass, int)
did not match C++ signature:
      GetX(class MyClass::LedPosition_C {lvalue}, int {lvalue} )

Any ideas?

Thanks
Alexander
