[bug-gnu-libiconv] iconv(3) return value

[Jeffrey Walton]

Hi All,

According to http://www.gnu.org/s/libiconv/documentation/libiconv/iconv.3.html:

  RETURN VALUE
    The iconv function returns the number of characters converted in a
    non-reversible way during this call; reversible conversions are not
    counted. In case of error, it sets errno and returns (size_t)(-1).

I'm not clear if it is the number of characters in the input buffer,
or number of characters output buffer?
