Yeah, I had adjusted all the socket_path/names in the file to UNIX_PATH_MAX as an initial fix but it spewed a different truncation warning as one of them gets a copy from dirent->d_name which is 256. So considering it's just an optimization of example code and hasn't really been developed over the last few years, I just fixed the warning that showed up.
