Windows Socket 编程 ： 支持多线程(TCP)(环境：VS2010)

Windows Socket 编程：支持多线程（TCP）（环境：VS2010）几点说明：

（1）发送的数据不能有空格；

（2）这是控制台应用程序；

1、UserMesInfo.h 公共文件，客户端和服务器端公用；

1 #ifndef User_Mes_Sock

2#define User_Mes_Sock

3 #include

4#endif

5

6const short MesLogin = 1001;

7const short MesError = 1002;

8const short MesNormal = 1003;

9const short LoginSuc = 1004;

10const short MesToAll = 1005;

11const short OnLineUser = 1010;

12

13

14//User Struct

15struct UserInfo

16 {

17short userId;

18char userName[32];

19 SOCKET userSock;

20 LONG userAddr;

21 UserInfo *pNext;

22 };

23

24//Message Struct

25struct MesInfo

26 {

27short MesType;

28char fromUserName[32]; 29char toUserName[32]; 30char MesContent[1024];

31 };

2、TCP：客户端程序
