<p style="margin-left:11%; margin-top: 1em">The
<b>iconv_open_into</b> function initializes a conversion

<i>tocode</i>. The conversion descriptor is stored in the
memory pointed to by <i>resultp</i>.</p>
<p style="margin-left:11%; margin-top: 1em">The values
permitted for <i>fromcode</i> and <i>tocode</i> are the same
as for the function <b>iconv_open</b>.</p>
<p style="margin-left:11%; margin-top: 1em">After a
successful return from this function, <i>resultp</i> can be
be used as an <b>iconv_t</b> object with the <b>iconv</b>
function.</p>
<h2>RETURN VALUE
<a name="RETURN VALUE"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
