是否有strcpy_s和/或TR24731-1的任何自由的实现？ [英] Are there any free implementations of strcpy_s and/or TR24731-1?

问题描述

我有一个旧的项目，是混合的C和C ++。它使strcat的，函数strncpy 的strcpy ，的$ C>， strncat函数等我发现了一些缓冲区溢出，我想使用更安全功能，如 strcpy_s 。 MSVC包括那些功能，但我需要的东西，将在各种平台上的工作 - 的Linux，OSX和Windows最少

I have an old project that is mixed C and C++. It makes extensive use of C strings and of strcpy,strcat,strncpy,strncat etc. I've uncovered a number of buffer overflows, and I'd like to use more secure functions, such as strcpy_s. MSVC includes those functions, but I need something that will work on various platforms - linux, osx, and windows at the least.

我知道的 strlcpy ，但很多人都注意到（例如），它真的不是一种进步。

I do know of strlcpy, but as plenty of people have noted (example), it really isn't an improvement.

所以：是否有 strcpy_s ， strcat_s 的任何自由的实现等，或者整个的 TR24731-1 ？

So: Are there any free implementations of strcpy_s, strcat_s, etc, or of the entire TR24731-1?

我需要的东西，要么公共领域或 BSD ，但如果你知道在其他许可实现，去前进，列出他们 - 我敢肯定，别人将受益

I need something that's either public domain or BSD, but if you know of implementations under other licenses, go ahead and list them - I'm sure someone else will benefit.

推荐答案

在安全的C库的尝试。这是 MIT许可下根据本的列表实现你要找的功能：

Try with the Safe C library. It's under the MIT license and according to this list implements the functions you're looking for:

安全C库提供了符合ISO / IEC TR24731边界检查内存和字符串函数。
  这些功能的替代功能，以现有的标准C库，促进更安全，更安全编程

The Safe C Library provides bound checking memory and string functions per ISO/IEC TR24731. These functions are alternative functions to the existing standard C library that promote safer, more secure programming
