linux下C语言utf-8编码与gb2312转换代码[转cu]

 

转自：


楼主，我给你一段代码。在linux gsoap和java axis webservice传数据屡试不爽。。。

int code_convert(char *from_charset, char *to_charset, char *inbuf, int inlen, char *outbuf, int outlen)
{
iconv_t cd;
int rc;
char **pin = &inbuf;
char **pout = &outbuf;

cd = iconv_open(to_charset, from_charset);

if (cd == 0)
return 1;

memset(outbuf, 0, outlen);

if (iconv(cd, pin, &inlen, pout, &outlen) == -1)
return 1;

iconv_close(cd);
return 0;
}

我也发一个自己写的程序，一直在用的

iconv_close( ct );

sout=strdup(buff);
free( buff );

return( sout );
}
