The zip archive specified by the open file descriptor <var class="Ar">fd</var>
  is opened and a pointer to a <var class="Ft">struct zip</var>, used to
  manipulate the archive, is returned. In contrast to
  <a class="Xr" href="zip_open.html">zip_open(3)</a>, using
  <code class="Nm">zip_fdopen</code> the archive can only be opened in read-only
  mode. The <var class="Ar">fd</var> argument may not be used any longer after
  calling <code class="Nm">zip_fdopen</code>. 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.
<div class="Bd-indent">

<p class="Pp">If an error occurs and <var class="Ar">errorp</var> is

Upon successful completion <code class="Fn">zip_fdopen</code>() returns a
  <var class="Ft">struct zip</var> pointer, and <var class="Ar">fd</var> should
  not be used any longer, nor passed to
  <a class="Xr" href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/close.html">close(2)</a>. Otherwise,
  <code class="Dv">NULL</code> is returned and <var class="Ar">*errorp</var> is
  set to indicate the error. In the error case, <var class="Ar">fd</var> remains
  unchanged.
