可重入函数要么使用本地变量，要么在使用全局变量时保护自己的数据。
Reentrant functions either use local variables or protect their data when global variables are used.
本文描述了在并行和并发程序设计中函数的不可重入性导致的一些潜在问题。
This article describes some potential problems due to non-reentrancy of the function in parallel and concurrent programming.
近来很多提供商已经开始提供标准c程序库的可重入版本，这是一个好消息。

注意，这里遵循了标准惯例，通过向函数名添加“_ r”后缀来命名可重入函数。
Note that this follows a standard convention for the naming of reentrant function by suffixing the function name with "_r".
如果底层的函数处于关键部分，并且生成并处理信号，那么这可能会导致函数不可重入。
If the underlying function is in the middle of a critical section and a signal is generated and handled, this can cause the function to be non-reentrant.
在早期的编程中，不可重入性对程序员并不构成威胁；函数不会有并发访问，也没有中断。
In the early days of programming, non-reentrancy was not a threat to programmers; functions did not have concurrent access and there were no interrupts.
