UnixLabels.lseek (for positioning a file descriptor),
  UnixLabels.truncate and UnixLabels.ftruncate
  (for changing the size of a file),
  and UnixLabels.stat, UnixLabels.lstat and UnixLabels.fstat
  (for obtaining information on files).  These alternate functions represent
  positions and sizes by 64-bit integers (type int64) instead of
  regular integers (type int), thus allowing operating on files
  whose sizes are greater than max_int.val lseek : UnixLabels.file_descr -> int64 -> mode:UnixLabels.seek_command -> int64
