-The main case is when <i>inbuf</i> is not NULL and
-<i>*inbuf</i> is not NULL. In this case, the <b>iconv</b>
-function converts the multibyte sequence starting at
-<i>*inbuf</i> to a multibyte sequence starting at
-<i>*outbuf</i>. At most <i>*inbytesleft</i> bytes, starting
-at <i>*inbuf</i>, will be read. At most <i>*outbytesleft</i>

-The <b>iconv</b> function converts one multibyte character
-at a time, and for each character conversion it increments
-<i>*inbuf</i> and decrements <i>*inbytesleft</i> by the
-number of converted input bytes, it increments
-<i>*outbuf</i> and decrements <i>*outbytesptr</i> by the
-number of converted output bytes, and it updates the
-conversion state contained in <i>cd</i>. The conversion can
-stop for four reasons:</td></table>

-1. An invalid multibyte sequence is encountered in the

-2. The input byte sequence has been entirely converted, i.e.

-3. An incomplete multibyte sequence is encountered in the

-A different case is when <i>inbuf</i> is NULL or
-<i>*inbuf</i> is NULL, but <i>outbuf</i> is not NULL and
-<i>*outbuf</i> is not NULL. In this case, the <b>iconv</b>
-function attempts to set <i>cd</i>'s conversion state to the
-initial state and store a corresponding shift sequence at
-<i>*outbuf</i>. At most <i>*outbytesleft</i> bytes, starting
-at <i>*outbuf</i>, will be written. If the output buffer has
-no more room for this reset sequence, it sets <b>errno</b>
-to <b>E2BIG</b> and returns (size_t)(-1). Otherwise it
-increments <i>*outbuf</i> and decrements <i>*outbytesptr</i>
-by the number of bytes written.</td></table>

-A third case is when <i>inbuf</i> is NULL or <i>*inbuf</i>
