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

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