[C++-sig] Wrapping out parameter for python access

Hi all
This is a classical issue in boost python. I.e. removeing an argument
from the function definition and adding the "returned", by the original
function, value to the return statement of the function-wrapper
For example :
The original function is:
inline void hello_world( std::string& hw ){
hw = "hello world!";
}
And the wrapper is:
inline std::string hello_world_wrapper()
{
std:string temp;
::hello_world(temp);
Return temp;
}
Py++ can help us to generate such wrapper, see
http://language-binding.net/pyplusplus/documentation/functions/transform
ation/built_in/output.html
But in this thread
(http://mail.python.org/pipermail/c++-sig/2005-June/009097.html ), Dave
provided a start to write a wrapping template.
In My case, only last parameter is out parameter and whether function
parameter count does not matter. The function signature looks like:
Return function (T1 t1, T2 t2, TOUT& out);
How to write a template for such function and integrate into def?
Any suggestion?
