strcpy_s和StringCchCopy [英] strcpy_s vs StringCchCopy

问题描述

尊敬的大师，

任何人都可以解释strcpy_s和StringCchCopy之间的区别吗?

我也想知道StrSafe.h中找到的函数与其他安全字符串函数(例如wcscpy_s等)之间的区别.

请建议最好使用哪个功能.

在此先谢谢您.

Dear Gurus,

Can anyone please explain the difference between strcpy_s and StringCchCopy?

I would also like to know the difference between the functions found in StrSafe.h and the other safe string functions like wcscpy_s etc.

Please advice which function is best to use.

Thanks in advance.

推荐答案

如果您真的想使用安全的"密码(它们并不是很安全，而且速度很慢)，我会同意的. strcpy_s.它是随CRT提供的，而StringCchCopy取决于Windows版本-仅在XP SP2及更高版本中受支持.

If you really want to use the "safe" ones (they are not really safe, and are slow), I''d go with strcpy_s. It is provided with CRT, whereas StringCchCopy depends on Windows version - it is supported only in XP SP2 and above.

它们都具有相同的作用. strcpy_s是标准C，另一个是 MFC 本机Windows API.

Google确实有效.试试这个链接:

They both do the same thing. strcpy_s is standard C, and the other is MFC a native Windows API.

Google really does work. Try this link:

两个版本均为"Sercure".
我个人更喜欢"StringCchCopy"版本，因为它们比* _S版本更干净，更一致.

问候，

Both Versions are "Sercure".
I personally prefer the "StringCchCopy" versions since they are cleaner and more consistent then the *_S versions.
