File operations on large files.

This sub-module provides 64-bit variants of the functions
|
|
<B>Unix.lseek</B>
|
|
|
|
(for positioning a file descriptor),
|
|
<B>Unix.truncate</B>
|
|
|
|
and
|
|
<B>Unix.ftruncate</B>
|
|
|
|
(for changing the size of a file),
|
|
and
|
|
<B>Unix.stat</B>
|
|
|
|
,
|
|
<B>Unix.lstat</B>
|
|
|
|
and
|
|
<B>Unix.fstat</B>
|
|
|
|
(for obtaining
|
|
information on files). These alternate functions represent
|
|
positions and sizes by 64-bit integers (type
|
|
<B>int64</B>
|
|
|
|
) instead of
|
|
regular integers (type
|
|
<B>int</B>
|
|
|
|
), thus allowing operating on files
|
|
whose sizes are greater than
|
|
<B>max_int</B>
|
|
|
|
.
