       Module LargeFile
        : sig end

       File  operations  on  large  files.  This sub-module provides 64-bit variants of the functions Unix.lseek
       (for positioning a file descriptor), Unix.truncate and Unix.ftruncate (for changing the size of a  file),
       and  Unix.stat  ,  Unix.lstat  and  Unix.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 : Unix.file_descr -> int64 -> Unix.seek_command -> int64

       val truncate : string -> int64 -> unit

       val ftruncate : Unix.file_descr -> int64 -> unit

       type stats = {
        st_dev : int ;  (* Device number *)
        st_ino : int ;  (* Inode number *)
        st_kind : Unix.file_kind ;  (* Kind of the file *)
        st_perm : Unix.file_perm ;  (* Access rights *)
        st_nlink : int ;  (* Number of links *)
        st_uid : int ;  (* User id of the owner *)
        st_gid : int ;  (* Group ID of the file's group *)
        st_rdev : int ;  (* Device minor number *)
        st_size : int64 ;  (* Size in bytes *)
        st_atime : float ;  (* Last access time *)
        st_mtime : float ;  (* Last modification time *)
        st_ctime : float ;  (* Last status change time *)
        }
