I have to disagree. byte access is the only way to escape from alignment issues, this is what your compiler do for packed struct if your target does not support unaligned access for short and long. This is why all structures that are going to be used in buffers are packed in lwIP, because the structure might be set to an unaligned address in the buffer. Anyway, lwIP is not designed to work with compilers that does not support packed structures. > Thanks for all your help! You're welcome :) Sylvain
