Hi Kilon,documentation is ���ongoing���, but I think the only way I will actually finish it is by answering questions from people (I���ve been pasting there the answers I give also in the list). So I would ask you to take a look into the doc and make all the questions that you want��� so I answer, and I will be closer to finish :)cheers,��EstebanOn 07 Sep 2016, at 15:01, Dimitris Chloupis <kilon.alios@gmail.com> wrote:Hey Esteban hows the documentation for UFFI going ? I will most likely go down the Memory Mapped File (Shared Memory) for uniting Pharo with Unreal instead of making a Pharo to C++ compiler since it will be much simpler for me but I will need the FFI. Is it stable enough both FFI and its documentation or should I wait more ?
