| The function <code class="Fn">zip_source_seek</code>() sets the current read |

| <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: |
