i'd expect the posix definition.
in posix "File types include regular file, character
special file, block special file, FIFO special file,
symbolic link, socket, and directory. Other types of
files may be supported by the implementation."
where regular file is "A file that is a randomly
accessible sequence of bytes, with no further
structure imposed by the system."
