Hi Robert
I've a ref_ptr to put to NULL, but I can't do a simple my_refptr = NULL;
I need to set it in a function.
In argument of my function, I get a ref_ptr, and in the function, I
put this ref_ptr to NULL;
I do not return anything.
Perhaps ref_ptr::release()?
Paul
but at the end (going out of the function), my original ref_ptr hasn't
been modified...
I don't know if it is more understandable, but it's not easy to explain...
Thanks for help.
Vincent.

Hi Vincent,
I don't know if anyone else can make sense of what you are trying to
do, based on your email, but I'm just lost. I kinda doubt the problem
is really about ref_ptr<>, but something related to the overall code
that you have written, but since I can't really spot what you intend
or what might be going on I certainly can't help.
Robert.
