Hi Maciej, Could you provide some details on how to use cffi buffers? (a simple demo code or documents) I tried the below code but it did not work.
#python list x=[1,2,3,4] #intend to convert to c++ char*, but failed p=ffi.from_buffer(x) #intend to covert back to python list, but failed y=ffi.buffer(p) Thanks! -Ethan On Fri, Aug 7, 2015 at 6:24 PM, Maciej Fijalkowski <fij...@gmail.com> wrote: > you can use cffi buffers (e.g. cffi char*) that you manipulate from > python using wrappers.
