This sub-module provides 64-bit variants of the functions
<a href="Unix.html#VALlseek"><code class="code"><span class="constructor">Unix</span>.lseek</code></a> (for positioning a file descriptor),
<a href="Unix.html#VALtruncate"><code class="code"><span class="constructor">Unix</span>.truncate</code></a> and <a href="Unix.html#VALftruncate"><code class="code"><span class="constructor">Unix</span>.ftruncate</code></a> (for changing the size of a file),
and <a href="Unix.html#VALstat"><code class="code"><span class="constructor">Unix</span>.stat</code></a>, <a href="Unix.html#VALlstat"><code class="code"><span class="constructor">Unix</span>.lstat</code></a> and <a href="Unix.html#VALfstat"><code class="code"><span class="constructor">Unix</span>.fstat</code></a> (for obtaining
information on files). These alternate functions represent
positions and sizes by 64-bit integers (type <code class="code">int64</code>) instead of
regular integers (type <code class="code">int</code>), thus allowing operating on files
whose sizes are greater than <code class="code">max_int</code>.<br>
