【转】VS 2005 CRT函数的安全性增强版本

Security-Enhanced Versions of CRT Functions

（CRT = C Runtime Library = C运行时间库）

 

为微软公司对C/C++语言的扩展，其中的一部分已于2003年提交给ISO作为C/C++标准下一版本的修改建议。

安全CRT函数，在原来函数名后添加了“_s”后缀；一般返回出错代码；并将原来的返回值，作为一个参数，添加到函数输入参数列表的最后；对带缓冲区参数的函数，还添加了表示缓冲区大小的输入参数，以防止溢出。

1．类型定义

下面是若干安全函数原型用到的类型定义：

#include <crtdefs.h>

typedef int errno_t;

typedef unsigned short wchar_t;

#ifdef _WIN64

typedef unsigned __int64    size_t;

#else

typedef _W64 unsigned int   size_t;

#endif

2．常用安全CRT函数

下面是若干最常用的安全CRT函数原型：
