Module LargeFile :
sig end

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

val truncate : string -> int64 -> unit

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