_STDC_ 推断编译器是否符合c标准,返回0或1:%d 条件编译: #define TEST 1 #if TEST //TEST为真时运行的代码 #endif #ifndef ABC_H //假设没定义,就定义宏 #define ABC_H //头文件定义 #endif #ifdef ABC_H //假设定义了宏,取消定义 #undef ABC_H ...
所以它在配置文件的开头处理和插入标准的头文件/usr/include/stdc-predef.h，您可以通过以下操作进行验证...
14. 在使用了“-traditional”开关后,预定义宏__STDC__不被定义,而 __GNUC__被定义(因为__GNUC__表明的GNU扩展不受“-traditional”开 关影响)。如果需要根据是否使用“-traditional”开关来决定头文件的工作 方式,可以通过检测这两个预定义宏来区别以下四种情况:GNU C、传 ...
