[;1m  read_link(Name)[0m

  Returns [;;4m{ok, Filename}[0m if [;;4mName[0m refers to a symbolic link that
  is not a raw filename, or [;;4m{error, Reason}[0m otherwise. On
  platforms that do not support symbolic links, the return value is [;;4m[0m
  [;;4m{error,enotsup}[0m.

  Typical error reasons:

   • [;;4meinval[0m - [;;4mName[0m does not refer to a symbolic link or the
     name of the file that it refers to does not conform to the
     expected encoding.

   • [;;4menoent[0m - The file does not exist.

   • [;;4menotsup[0m - Symbolic links are not supported on this
     platform.
