Unix網絡編程chapter1 示例程序改寫為Winsock

Unix網絡編程chapter1 示例程序改寫為Winsock：

Sever端：

1. #include"WinSock2.h"
2. #include "time.h"
3. #include "stdio.h"
5. #include <iostream>
7. #pragma comment(lib,"WS2_32")
9. using namespace std;
11. const int MaxLine = 1024;
13. int main()
14. {
15. int lRet = 0;
16. WSADATA lWsaData;
17. if ((lRet = WSAStartup(MAKEWORD(2,2), &lWsaData)) != 0)
18. {
19. cout << "Error " << lRet << endl;
20. return 0;
21. }
23. int lListen = 0, lConnfd = 0;
24. SOCKADDR_IN lServAddr;
25. char lBuf[MaxLine];
26. time_t lTicks;
28. lServAddr.sin_family = AF_INET;
29. lServAddr.sin_addr.s_addr = htonl(INADDR_ANY);
30. lServAddr.sin_port = htons(13);
32. SOCKET lSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
33. if (INVALID_SOCKET == lSocket)
34. {
35. cout << "INVALID_SOCKET" << endl;
36. return 0;
37. }
38. bind(lSocket,(sockaddr*)(&lServAddr),sizeof(lServAddr));
39. listen(lSocket,5);
41. while(true)
42. {
43. SOCKET lSeverSocket = accept(lSocket,(sockaddr*)NULL,NULL);
44. lTicks = time(NULL);
45. sprintf(lBuf, "%.24s\r\n", ctime(&lTicks));
46. send(lSeverSocket,lBuf,strlen(lBuf),0);
47. closesocket(lSeverSocket);
48. }
49. }

Client 端：

1. #include<WinSock2.h>
3. #include <iostream>
4. #include <string>
6. using namespace std;
8. #pragma comment(lib, "WS2_32")
10. const int MaxLine = 1024;
12. int main()
13. {
14. char lReadline[MaxLine];
15. int lRet = 0;
16. WSADATA lWsaData;
17. if ((lRet = WSAStartup(MAKEWORD(2,2), &lWsaData)) != 0)
18. {
19. cout << "Error " << lRet << endl;
20. return 0;
21. }
22. SOCKADDR_IN lAddr;
23. lAddr.sin_family = AF_INET;
24. lAddr.sin_port = htons(13);
26. SOCKET lSocket = socket(AF_INET, SOCK_STREAM, 0);
27. if (INVALID_SOCKET == lSocket)
28. {
29. cout << "INVALID_SOCKET" << endl;
30. return 0;
31. }
32. lAddr.sin_addr.s_addr = inet_addr("192.168.1.102");
33. if (connect(lSocket,(sockaddr*)(&lAddr),sizeof(lAddr)) < 0 )
34. {
35. cout << "connect error" << endl;
36. return 0;
37. }
38. int lNum = 0;
39. if ( (lNum = recv(lSocket,lReadline,MaxLine,0)) > 0)
40. {
41. string lStr(lReadline,lNum-1);
42. cout << lStr << endl;
43. }
44. return 0;
45. }

具體含義可以參考原書，Stevens大師已經事無巨細地把每行代碼都做了解釋，感覺很適合初���者學習。

對於網絡編程，我是初學者，在這裡想把書中的原理搞明白，把代碼自己敲成winsock下的，至少把代碼重新看一遍吧，呵呵。
