strncat

Both strncpy ( 3 ) and strncat ( 3 ) require that you give the amount of space left , not the total size of the buffer .

strncpy（3）和strncat（3）都要求您给出剩余的空间，而不是给出缓冲区的总大小。

Memcpy () joins the ranks of other popular functions like strcpy , strncpy , strcat , strncat which were banned due to their security vulnerability through buffer overruns .

memcpy（）加入到strcpy，strncpy，strcat，strncat等常用函数的队伍中，都是由于可通过缓存溢出进行安全攻击而被禁用。

Then , we 'll discuss two examples of the static approach ( standard C strncpy / strncat and OpenBSD 's strlcpy / strlcat ), followed by two examples of the dynamic approach ( SafeStr and C + + 's std : : string ) .

然后，我们将讨论静态方法的两个例子（标准Cstrncpy/strncat和OpenBSD的strlcpy/strlcat），接着讨论动态方法的两个例子（SafeStr和C++的std：：string）。
