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
.
