Thanks. When I think of it, I have noticed other instances with get /
set before. As for me fixing the documentation for this member, I was
not exactly sure what it does (return current info, return passed info
from previous call to SetInformationInput) but I know that it does not
do what the documentation says.. The documentation appears to be
correct for the SetInformationInput() however.
