typedef in c 1.typedef: The typedef is used to give data type a new name. For example, //After this line BYTE can be used//in place of unsigned chartypedef unsignedcharBYTE;intmain() { BYTE b1, b2; b1='c'; printf("%c", b1);return0; } 2.How to use the typedef struct in ...

define是宏定义,typedef是重命名。 typedef int int_32; typedef void(*Func)(int); // Func为一个函数指针 #define PI 3.1415 // 宏定义没有; #define max(x,y) ((x)>(y)?(x):(y)) 作用域不同 typedef (1)如果放在所有函数之外,它的作用域就是从它定义开始直到文件尾; (2)如果放在某...

(CCommand::*): 表示这是一个指向CCommand类的成员函数的指针。 CMDFUNC: 是这个指针类型的新名称。 2. 函数参数 (std::list<CPacket>&, CPacket& inPacket): 表示这个成员函数接收两个参数: 第一个参数是std::list<CPacket>&:这是一个对std::list<CPacket>的引用,表示你可以通过这个引用修改列表中...
