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

See lseek.

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

See truncate.

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

See ftruncate.
