Dear sir or madame,
I encounter a big problem
with ICONV,I need your help;
In http://www.gnu.org/software/libiconv/documentation/libiconv/iconv.3.html
It says,
|
1.
An invalid multibyte sequence is encountered in the input. In this case it
sets errno to EILSEQ and returns (size_t)(-1). *inbuf is left pointing to the beginning
of the invalid multibyte sequence. |
|
|
2.
The input byte sequence has been entirely converted, i.e. *inbytesleft has gone down to 0. In this
case iconv returns the number of
non-reversible conversions performed during this call. |
|
|
3.
An incomplete multibyte sequence is encountered in the input, and the input
byte sequence terminates after it. In this case it sets errno to EINVAL and returns (size_t)(-1). *inbuf is left pointing to the beginning of the incomplete
multibyte sequence. |
|
|
4.
The output buffer has no more room for the next converted character. In this
case it sets errno to E2BIG and returns (size_t)(-1). |
But I write a simple
program use Microsoft visual 6.0.
The return is
(size_t)(-1),but the errno does not change.I am fuzzy.
Please help me.
Regards,
Sun,gao
