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 C strncpy/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 )。
