我们觉得，缺乏统一性是导致现有许多C 语言字符串处理函数容易产生安全漏洞的根本原因，而strsafe 系列函数所带来的高度统一性恰恰是解决此问题的一剂良药。
We feel it is a lack of uniformity that makes many existing C runtime string-handling functions susceptible to security errors, and the extra consistency in strsafe should help remedy the problem.

该样例是一个称为getFeedFromURL 的处理事件，该事件可以接受一个字符串作为负载并在被触发时调用函数handleGetFeedFromURL。
This sample is a handle event called getFeedFromURL, which can receive a string as payload and invoke the function handleGetFeedFromURL when it is triggered.
若要查看字符串ing是否出现在文件文本中，请使用index函数，该函数返回ing首次出现的位置，这样您就可以使用它来进行进一步的字符串处理。
To see if the string ing is present in the file text, use the index function, which returns the location of the first occurrence of ing so that you can use it for further string processing.
但是fn：boolean和xs： boolean与此不同，这两个函数以不同的方式处理字符串。

当要编写规则处理多个相似的设备时，udev可以使用类似C语言的printf函数中的字符串替换操作符。
When writing rules which will potentially handle multiple similar devices, udev's printf-like string substitution operators are very useful.
现在我们处理的不是C语言和它的数组，我们想用字符串偏移量，所以我们需要一个哈希函数，为每个键值计算出一个数值。
Now we're not dealing with C and C arrays but also want to use string offsets so we need a function to calculate a numeric value, a hash, for each key.
