The function <code class="Fn">zip_file_add</code>() adds a file to a zip
archive, while <code class="Fn">zip_file_replace</code>() replaces an existing
file in a zip archive. The argument <var class="Ar">archive</var> specifies
the zip archive to which the file should be added. <var class="Ar">name</var>
is the file's name in the zip archive (for
<code class="Fn">zip_file_add</code>()), while <var class="Ar">index</var>
specifies which file should be replaced (for
<code class="Fn">zip_file_replace</code>()). The <var class="Ar">flags</var>
argument can be any combination of <code class="Dv">ZIP_FL_OVERWRITE</code>
with one of <code class="Dv">ZIP_FL_ENC_*</code>:
<dl class="Bl-tag">
<dt><a class="permalink" href="#ZIP_FL_OVERWRITE"><code class="Dv" id="ZIP_FL_OVERWRITE">ZIP_FL_OVERWRITE</code></a></dt>
<dd>Overwrite any existing file of the same name. For
<code class="Nm">zip_file_add</code> only.</dd>
<dt><a class="permalink" href="#ZIP_FL_ENC_GUESS"><code class="Dv" id="ZIP_FL_ENC_GUESS">ZIP_FL_ENC_GUESS</code></a></dt>
<dd>Guess encoding of <var class="Ar">name</var> (default). (Only CP-437 and
UTF-8 are recognized.)</dd>
<dt><a class="permalink" href="#ZIP_FL_ENC_UTF_8"><code class="Dv" id="ZIP_FL_ENC_UTF_8">ZIP_FL_ENC_UTF_8</code></a></dt>
<dd>Interpret <var class="Ar">name</var> as UTF-8.</dd>
<dt><a class="permalink" href="#ZIP_FL_ENC_CP437"><code class="Dv" id="ZIP_FL_ENC_CP437">ZIP_FL_ENC_CP437</code></a></dt>
<dd>Interpret <var class="Ar">name</var> as code page 437 (CP-437).</dd>
</dl>
The data is obtained from the <var class="Ar">source</var> argument, see
<a class="Xr" href="zip_source.html">zip_source(3)</a>.
<p class="Pp"><i class="Em">NOTE</i>:
<a class="Xr" href="zip_source_free.html">zip_source_free(3)</a> should not
be called on a <var class="Ar">source</var> after it was used successfully
in a <code class="Nm">zip_file_add</code> or
<code class="Nm">zip_file_replace</code> call.</p>
<p class="Pp">Please also note that when using
<code class="Nm">zip_replace</code>, the target file's extra field
information will be deleted since this usually is dependent on the file
contents. If you want to keep them, query them beforehand with
<a class="Xr" href="zip_file_extra_field_get.html">zip_file_extra_field_get(3)</a>
and restore them after <code class="Nm">zip_replace</code> with
<a class="Xr" href="zip_file_extra_field_set.html">zip_file_extra_field_set(3)</a>.</p>

<section class="Sh">
<h1 class="Sh" id="RETURN_VALUES"><a class="permalink" href="#RETURN_VALUES">RETURN
VALUES</a></h1>
Upon successful completion, <code class="Fn">zip_file_add</code>() returns the
index of the new file in the archive, and
<code class="Fn">zip_file_replace</code>() returns 0. Otherwise, -1 is
returned and the error code in <var class="Ar">archive</var> is set to
indicate the error.
