#ifdef的用法详解
引用中提到了Linux底层代码中出现的#define、#ifdef和#endif。而引用中介绍了在C编程中经常遇到的#ifdef和#endif的使用方式。通过这些宏定义和条件编译指令,可以根据不同的平台进行代码的移植,提高软件的移植性。而引用中指出,#ifdef CONFIG_XXX只能判断是否设置为y,即编译进内核。据此我们可以得出结论:#ifdef __linux是用来判断是否在Linux平台下进行编译的条件预编译指令。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
