The <code class="Fn">zip_set_archive_comment</code>() function sets the comment
for the entire zip archive. If <var class="Ar">comment</var> is
<code class="Dv">NULL</code> and <var class="Ar">len</var> is 0, the archive
comment will be removed. <var class="Ar">comment</var> must be encoded in
ASCII or UTF-8.

Upon successful completion 0 is returned. Otherwise, -1 is returned and the
error information in <var class="Ar">archive</var> is set to indicate the
error.
