To be clear: there's only one error code that is important here and that's the "buffer is too short" when encoding the data. TinyCBOR has that in a special bit that no other error code will set, so it's guaranteed to work. Moreover, you *can* continue streaming data after you got such an error and TinyCBOR will then simply count how many bytes it needs, instead of encoding. At the end, you can allocate the buffer of the size that TinyCBOR says it should be and encoding should work (provided you have the same data, of course). -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
