根据用法的不同,分两种,Object-like 和 Function-like。前者用于 Object 对象,后者用于函数方法。 C/C++ 代码编译过程中,可通过相应参数来获取到各编译步骤中的产出,比如想看被预处理编译之后的宏,使用gcc使加上-E参数。 $ gcc -E macro.c 宏的定义 通过#define指令定义一个宏。 #defineNAME_OF_MACRO value...
Macro=为其定义的宏; //参数还没有展开,只针对宏体 else return Macro; //如果被修饰则不对它展开直接返回 for(对该Macro的参数进行遍历 : i=0 -> N) if(parameter[i]存在于macro[]中) parameter[i]=MacroSubstitute(parameter[i],macro); //对参数进行展开,递归调用宏替换程序 if(Macro在macro[]中)...

For example, if you want to use 'args' instead of __VA_ARGS__, you can define your macro like this: #define IDARRAY(args...) (id []){ args } And something you should keep in mind when you want to write macro: wherever you can use an inline function instead of a macro, ...

1.inline是给编译器的建议,函数放在头文件中并在定义时添加,在类声明时直接写的方法体,等同与添加了inline内联; 2.struct、class、enum、union最后面记得加分号,namespace最后没有分号; 3.默认参数是声明时使用的,默认参数必须在后边; 4.virtual 在父类中声明才有意义,只在子类中声明是错误的。子类中的virtual...

To get more detailed information, generated function prototypes can be extracted with the scripts/flatcc-doc.sh script. Some are also concerned with macros being "unsafe". Macros are not unsafe when used with FlatCC because they generate static or static inline functions. These will trigger ...
