16       File  operations on large files.  This sub-module provides 64-bit vari‐
17       ants of the functions Unix.LargeFile.lseek (for positioning a file  de‐
18       scriptor),  Unix.LargeFile.truncate  and  Unix.LargeFile.ftruncate (for
19       changing the size of a file),  and  Unix.LargeFile.stat  ,  Unix.Large‐
20       File.lstat  and  Unix.LargeFile.fstat  (for  obtaining  information  on
21       files).  These alternate functions represent  positions  and  sizes  by
22       64-bit  integers (type int64 ) instead of regular integers (type int ),
23       thus allowing operating on files whose sizes are greater than max_int .
