<p class="Pp">The
<a class="permalink" href="#zip_get_archive_comment"><code class="Fn" id="zip_get_archive_comment">zip_get_archive_comment</code></a>()
function returns the comment for the entire zip archive. The return value is
in UTF-8 encoding unless <code class="Dv">ZIP_FL_ENC_RAW</code> was
specified (see below). This pointer should not be modified or
<a class="Xr" href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/free.html">free(3)</a>'d, and becomes invalid when
<var class="Ar">archive</var> is closed. If <var class="Ar">lenp</var> is
not <code class="Dv">NULL</code>, the integer to which it points will be set
to the length of the comment. If <var class="Ar">flags</var> is set to
<code class="Dv">ZIP_FL_UNCHANGED</code>, the original unchanged comment is
returned.</p>

<dd>(Default.) Guess the encoding of the archive comment in the ZIP archive

recognized.)</dd>
