A rather involved upgrade for both files and directories, seek and related functions are now completely supported: - lfs_file_seek - lfs_file_tell - lfs_file_rewind - lfs_file_size - lfs_dir_seek - lfs_dir_tell - lfs_dir_rewind This change also highlighted the concern that lfs_off_t is unsigned, whereas off_t is traditionally signed. Unfortunately, lfs_off_t is already used intensively through the codebase, so in focusing on moving forward and avoiding getting bogged down by details, I'm going to keep it as is and use the signed type lfs_soff_t where necessary.
