c/c++ code Linux 转码

linux下的转码是通过 iconv 模块实现的

废话少说，直接上源码

#include <stdio.h>
#include <iconv.h>
#include <string.h>

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,(size_t *)&inlen,pout,(size_t*)&outlen)==-1) return -1; 
        iconv_close(cd); 
        return 0; 
}
void main(int argc,char ** argv)
{
    char * utf8Char = "嘎嘎哈哈哈哈哈哈"; //请在utf8下编辑此文件
    printf("%s",utf8Char);
    char  gb2312Char[255] = "";
    code_convert("gb2312","utf-8",utf8Char,strlen(utf8Char),gb2312Char,255);
    printf("%s",gb2312Char);
}
