最有效的编码方式，无论是在输入还是运行时性能方面，可能是使用 gperf.

The most efficient way to code this, both in terms of typing and run-time performance, is probably to use gperf.

基本上，你输入你想要的名字列表，以及你想要映射到什么(数组索引、变量指针等等)，它会生成 C 代码来为你做这些.

Basically, you type the list of names you want, and what you want that to map to (array index, variable pointer, whatever) and it will generate C code to do that for you.

唯一的问题是你必须先学会如何使用它.

The only problem is that you have to learn how to use it first.

以下是一些真实代码的示例:conf.cconfitems.gperf/a>

Here's an example from some real-world code: conf.c confitems.gperf

请注意，gperf 文件将字符串映射到 C 宏，因此程序员可以将他们喜欢的任何内容放入该宏中，甚至可以在不同的地方将其用于不同的目的.然后 C 文件包含生成的代码，并调用生成的函数 confitems_get 进行映射:字符串输入，宏内容输出.

Note that the gperf file maps a string to a C macro so the programmer can put whatever they like inside that macro, and even use it for different purposes in different places. The C file then includes the generated code, and call the generated function confitems_get to do the mapping: string in, macro contents out.
