module LargeFile: sig .. end
File operations on large files.
  This sub-module provides 64-bit variants of the functions
  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.
