以下是重构后的代码:
```c

// 从获得的query_string解析查询字段,进行兴许操作。

以下是根据提供的内容重构的代码,并保持了段落结构:

这段代码是将一些C语言标准库函数重命名为FCGI_版本号的函数。这样做的目的是为了避免与其他C语言标准库函数名冲突,同时保持代码的兼容性。例如,getc被重命名为FCGI_fgetc,getchar被重命名为FCGI_getchar,等等。
这些重构后的函数和原来的函数在功能上是相同的,但是它们使用了不同的名称。这意味着在使用这些函数时,需要确保正确地引用它们的新名称。
```c
#ifndef _FCGI_STDIO
#define _FCGI_STDIO
// undef pclose
#undef pclose
#define pclose FCGI_pclose
// terminate extern "C" {
#if defined (__cplusplus) || defined (c_plusplus)
} /* terminate extern "C" { */
#endif
#endif /* _FCGI_STDIO */
