        : sig end

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

       See lseek .

       val truncate : string -> len:int64 -> unit

       See truncate .

       val ftruncate : UnixLabels.file_descr -> len:int64 -> unit

       See ftruncate .
