The zip archive specified by the open file descriptor
<var class="Ar" title="Ar">fd</var> is opened and a pointer to a
<var class="Ft" title="Ft">struct zip</var>, used to manipulate the archive,
is returned. In contrast to
<a class="Xr" title="Xr" href="zip_open.html">zip_open(3)</a>, using
<code class="Nm" title="Nm">zip_fdopen</code> the archive can only be opened
in read-only mode. The <var class="Ar" title="Ar">fd</var> argument may not be
used any longer after calling <code class="Nm" title="Nm">zip_fdopen</code>.
The <var class="Fa" title="Fa">flags</var> are specified by
<i class="Em" title="Em">or</i><span class="No">'ing</span> the following
values, or 0 for none of them.

<dd>Perform additional stricter consistency checks on the archive, and error

If an error occurs and <var class="Ar" title="Ar">errorp</var> is
<span class="No">non-</span><code class="Dv" title="Dv">NULL</code>, it will
be set to the corresponding error code.
<h1 class="Sh" title="Sh" id="RETURN_VALUES"><a class="permalink" href="#RETURN_VALUES">RETURN
VALUES</a></h1>
Upon successful completion <code class="Fn" title="Fn">zip_fdopen</code>()
returns a <var class="Ft" title="Ft">struct zip</var> pointer, and
<var class="Ar" title="Ar">fd</var> should not be used any longer, nor passed
to <a class="Xr" title="Xr" href="close.html">close(2)</a>. Otherwise,
<code class="Dv" title="Dv">NULL</code> is returned and
<var class="Ar" title="Ar">*errorp</var> is set to indicate the error. In the
error case, <var class="Ar" title="Ar">fd</var> remains unchanged.
