content: 赵老师,我那可是去面试啊.对方是做防火墙的.好想成功面试啊.,可惜. 另外谢谢zhangxiangDavaid 的提议,但现在c的公司字符串拷贝真的流行用memmove吗?那memcpy不更快吗?另外,我自己感觉这函数要使其安全的话,还得自己先设置一下条件啊. 还有刚查了有人推荐的一个非c标准的strlcpy. 哎,没进过正规军,自己还得继续努力啊! 再次感谢大家的回答!进不了正规军,我就当个好伪军吧!

content: 谢谢 user-5的回答. 我也想到了strcpy_s ,但是我也想起了cplusplus论坛里面的老外有说I agree that for portability strcpy_s should be avoided.所以我就放弃了说这个函数. 哎,想进c/c++行业这么难啊. 再次感谢您的回答!
