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.
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.
