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
.
