# Module UnixLabels.LargeFile

    module LargeFile: sig .. end

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

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