# Module Unix.LargeFile

    module LargeFile: sig .. end

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

See `lseek`.

    val truncate : string -> int64 -> unit

See `truncate`.

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

See `ftruncate`.
