In article [ref] (at Fri, 28 Nov 2003 09:23:26 +0900 (JST)), YOSHIFUJI Hideaki / 吉藤英明 [off-list ref] says:
2) memset(dst, 0, len);
strncpy(dst, src, len);
oops, this should be
memset(dst, 0, len);
if (len > 0)
strncpy(dst, src, len - 1);
3) if (len)
strncpy(dst, src, len - 1);
dst[len] = 0;
(or, say, strncpy0()).Note: in this case, we need to fix strncpy() first to zero-out rest of destination buffer. --yoshfuji
