Swig Problem string&

[Amitabh Saikia]

Hi

I have created a simple function called 'addTheString(string& str,
string appstr)' and the intension
is to append the 'appstr' to 'str' and use 'str'.

I tried swigging this method. My swigtest.i file is okay as I think
I have added both
- stl.i at top
- std_string.i

However, I am running into the problem. I get error messages as follows

-- error --
TypeError: argument number 1: a 'std::string&' is expected,
-- end error --

I tried the mailing list solution posted by Mr. Chiang, but its not
helping me.
Could you please help me out.

Thanks
