为什么strcpy_s不存在于我的系统的任何地方？ [英] Why does strcpy_s not exist anywhere on my system?

问题描述

我在Debian 8系统上使用 clang 。我有标准的C ++头文件。但是，没有定义 strcpy_s 的头文件。这是为什么？

I'm using clang on a Debian 8 system. I have the standard C++ headers. And yet, there is no header defining strcpy_s. Why is this?

# grep -iRHI 'strcpy_s' /usr 2>/dev/null
/usr/include/x86_64-linux-gnu/bits/string2.h:                ? __strcpy_small (dest, __strcpy_args (src),             \
/usr/include/x86_64-linux-gnu/bits/string2.h:__STRING_INLINE char *__strcpy_small (char *, __uint16_t, __uint16_t,
/usr/include/x86_64-linux-gnu/bits/string2.h:__strcpy_small (char *__dest,
/usr/include/x86_64-linux-gnu/bits/string2.h:__STRING_INLINE char *__strcpy_small (char *, __STRING2_COPY_ARR2,
/usr/include/x86_64-linux-gnu/bits/string2.h:__strcpy_small (char *__dest,
/usr/src/broadcom-sta-6.30.223.248/src/include/bcmutils.h:#define bcm_strcpy_s(dst, noOfElements, src)            strcpy((dst), (src))

推荐答案

显然，这些不存在，因为它们不存在，我可以通过查找和安装它们来找到并安装它们;或者，也可以自己编写它们。这是一个有帮助的解决方案，所以让upvotes开始。

Apparently, these don't exist because they don't exist. And I can find and install them by finding and installing them; or, alternatively, by coding them myself. Apparently this is a helpful solution, so let the upvotes begin.
