[bug-gnu-libiconv] iconv(3), E2BIG, and outbuf, outbytesleft

Hi All,

I'm working in C++, and I would like to convert string -> wstring.

Is there a way to determine the required output buffer size in advance?

If no, I believe I can loop on inbyteleft. But I can't tell if outbuf
and outbytesleft are updated on when { -1, E2BIG } is returned.  Is
outbuf and outbytesleft updated when the input exceeds the output?
