关于strcpy（）的设计考虑 [英] about design consideration of strcpy()

问题描述

strcpy（）返回它的输入参数。我在

c ++上问了一个类似的问题，大多数人似乎并不认为这是一个有问题的设计。你怎么想？b $ b想到这个？

strcpy() returns it''s input parameter. i asked a similar question on
c++, most people seem to not think it as a problemic design. how do you
think of this?

我无法想象C ++人们对C的了解。绝对是

strcpy'的设计没什么不错。

I can''t imagine what the C++ folks know about C. There is absolutely
nothing wrong with strcpy''s design.

设计中的一切都错了：


1）没有规定对于字符串的边界。 strcpy是最常见的
经常被发现的缓冲区溢出和内存覆盖的罪魁祸首。

2）返回值没有提供错误报告。这是

在大多数情况下设计不好。

3）返回值没有返回有用的信息。

Everything is wrong in that design:

1) No provision for bounds of the character strings. strcpy is the most
often found culprit of buffer overflows and memory overwrites.
2) The return value makes no provision for error reporting. This is
in most cases a bad design.
3) The return value returns no useful information.
