<p class="Pp">The
<a class="permalink" href="#zip_file_extra_field_delete"><code class="Fn" id="zip_file_extra_field_delete">zip_file_extra_field_delete</code></a>()
function deletes the extra field with index
<var class="Ar">extra_field_index</var> for the file at position
<var class="Ar">index</var> in the zip archive.</p>
<p class="Pp">If <var class="Ar">extra_field_index</var> is
<code class="Dv">ZIP_EXTRA_FIELD_ALL</code>, then all extra fields will be
deleted.</p>
<p class="Pp">The following <var class="Ar">flags</var> are supported:</p>
<div class="Bd-indent">
<dl class="Bl-tag">
<dt id="ZIP_FL_CENTRAL"><a class="permalink" href="#ZIP_FL_CENTRAL"><code class="Dv">ZIP_FL_CENTRAL</code></a></dt>
<dd>Delete extra fields from the archive's central directory.</dd>
<dt id="ZIP_FL_LOCAL"><a class="permalink" href="#ZIP_FL_LOCAL"><code class="Dv">ZIP_FL_LOCAL</code></a></dt>
<dd>Delete extra fields from the local file headers.</dd>
</dl>
</div>
<p class="Pp" id="zip_file_extra_field_delete_by_id">The
<a class="permalink" href="#zip_file_extra_field_delete_by_id"><code class="Fn">zip_file_extra_field_delete_by_id</code></a>()
function deletes the extra field with ID (two-byte signature)
<var class="Ar">extra_field_id</var> and index
<var class="Ar">extra_field_index</var> (in other words, the
<var class="Ar">extra_field_index</var><span class="No">'th</span> extra
field with ID <var class="Ar">extra_field_id</var>) The other arguments are
the same as for <code class="Fn">zip_file_extra_field_delete</code>()
(<code class="Dv">ZIP_EXTRA_FIELD_ALL</code> will delete all extra fields of
the specified ID).</p>
<p class="Pp">Please note that due to the library design, the index of an extra
field may be different between central directory and local file headers. For
this reason, it is not allowed to specify both
<code class="Dv">ZIP_FL_CENTRAL</code> and
<code class="Dv">ZIP_FL_LOCAL</code> in <var class="Ar">flags</var>, except
when deleting all extra fields (i.e.,
<var class="Ar">extra_field_index</var> being
<code class="Dv">ZIP_EXTRA_FIELD_ALL</code>).</p>
