Module LargeFile
 : 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 .
