The <code class="Fn">zip_open</code>() function opens the zip archive specified
by <var class="Ar">path</var> and returns a pointer to a
<var class="Ft">struct zip</var>, used to manipulate the archive. The
<var class="Fa">flags</var> are specified by
<i class="Em">or</i><span class="No">'ing</span> the following values, or 0
for none of them.

indicate the error, while
<code class="Fn">zip_open_from</code>(<var class="Fa">source</var>) sets
