[Opencxx-users] Re: [opencxx] How to change the function return type

This is a good question. I am not sure if OpenC++ lets you do it
out-of-the-box. If you figure out that you want to implement this
functionality by yourself, have a look at Member::SetArgumentList()
and search for 'new_args' in member.{h,cc} .

Best regards
