If the character +encoding of the input is stateful, the <b>iconv</b> function +can also convert a sequence of input bytes to an update of +the conversion state without producing any output bytes; +such input is called a <i>shift sequence</i>. The conversion +can stop for four reasons:</p> +<!-- INDENTATION --> +<p>1. An invalid multibyte sequence is encountered in the +input. In this case it sets <b>errno</b> to <b>EILSEQ</b> +and returns (size_t)(−1). <i>*inbuf</i> is left +pointing to the beginning of the invalid multibyte +sequence.</p> +<!-- INDENTATION --> +<p>2. The input byte sequence has been entirely converted, +i.e. <i>*inbytesleft</i> has gone down to 0. In this case +<b>iconv</b> returns the number of non-reversible +conversions performed during this call.</p> +<!-- INDENTATION --> +<p>3. An incomplete multibyte sequence is encountered in the +input, and the input byte sequence terminates after it. In +this case it sets <b>errno</b> to <b>EINVAL</b> and returns +(size_t)(−1). <i>*inbuf</i> is left pointing to the +beginning of the incomplete multibyte sequence.</p> +<!-- INDENTATION --> +<p>4. The output buffer has no more room for the next +converted character. In this case it sets <b>errno</b> to +<b>E2BIG</b> and returns (size_t)(−1).</p> +<!-- INDENTATION --> +<p>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).
