#include <iostream>#include <fstream>#include <iconv.h>int main(int argc, char *argv[]){ char src[] = "abcčde"; char dst[100]; size_t srclen = 6; size_t dstlen = 12; fprintf(stderr,"in: %s\n",src); char * pIn = src; char * pOut = ( char*)dst; iconv_t conv = iconv_open("UTF-8","CP1250"); iconv(conv, &pIn, &srclen, &pOut, &dstlen); iconv_close(conv); fprintf(stderr,"out: %s\n",dst);}
這裡要注意 iconv(conv, &pIn, &srclen, &pOut, &dstlen);
若返回 -1 則要查看 錯誤處理 errno
若是 #define E2BIG 7 /* Arg list too long */
則表示 dstlen 給的長度小於 轉換後的長度!!
