The function <code class="Fn">zip_source_seek</code>() sets the current read
offset for <var class="Fa">source</var>. Just like in
<a class="Xr" href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/fseek.html">fseek(3)</a>, depending on the
<var class="Ar">whence</var> argument, the <var class="Ar">offset</var> is
counted relative from:
<div class="Bd-indent">
<dl class="Bl-tag">
<dt><a class="permalink" href="#SEEK_SET"><code class="Dv" id="SEEK_SET">SEEK_SET</code></a></dt>
<dd>start of file</dd>
<dt><a class="permalink" href="#SEEK_CUR"><code class="Dv" id="SEEK_CUR">SEEK_CUR</code></a></dt>
<dd>current read offset in file</dd>

</dl>
</div>
</section>
<section class="Sh">
<h1 class="Sh" id="RETURN_VALUES"><a class="permalink" href="#RETURN_VALUES">RETURN
VALUES</a></h1>
Upon successful completion 0 is returned. Otherwise, -1 is returned and the
error information in <var class="Ar">source</var> is set to indicate the
error.
