TCP和服务器断开连接后重连怎么处理

zk5856 2010-11-09 03:37:56

和服务器连接有时会断线断线之后不知道怎么施放原来的socket
这是我的初始化

void CPVZNetMsgMng::NetStartNet()

{



	//初始化环境

	WSADATA WsaData;

	WORD Version=MAKEWORD(2,2);

	WSAStartup(Version,&WsaData);

	//建立socket

	m_sMainSocket=socket(AF_INET,SOCK_STREAM,0);

	sockaddr_in ReceiveAddr;

	ZeroMemory(&ReceiveAddr,sizeof(ReceiveAddr));

	ReceiveAddr.sin_family=AF_INET;

	ReceiveAddr.sin_port=htons(8899);	

	ReceiveAddr.sin_addr.s_addr=inet_addr("219.134.186.3");	

	//ReceiveAddr.sin_addr.s_addr=inet_addr("192.168.1.138");	

	int SetupStat=connect(m_sMainSocket,(sockaddr*)&ReceiveAddr,sizeof(ReceiveAddr));

	if (SetupStat==SOCKET_ERROR)

	{

		return;

	}



}

断线之后
是否要WSACleanup();?
如果用原来的socket该怎么处理施放
我是这样做的
WSACleanup();
NetStartNet();
貌似连不上...
请教达人帮助谢谢

是不是先
setsockopt(m_sMainSocket,SOL_SOCKET ,SO_REUSEADDR,(const char*)&bReuseaddr,sizeof(BOOL));
然后
sockaddr_in ReceiveAddr;
ZeroMemory(&ReceiveAddr,sizeof(ReceiveAddr));
ReceiveAddr.sin_family=AF_INET;
ReceiveAddr.sin_port=htons(8899);
ReceiveAddr.sin_addr.s_addr=inet_addr("192.168.1.138");
int SetupStat=connect(m_sMainSocket,(sockaddr*)&ReceiveAddr,sizeof(ReceiveAddr));
就重新连了?

只要关闭套接字之后再次连接就行了是吧

Uint WINAPI conn(PVOID p)

{

 CloseSocket(m_sMainSocket);

 m_sMainSocket=socket(AF_INET,SOCK_STREAM,0);

 if(connect(m_sMainSocket,(sockaddr*)&ReceiveAddr,sizeof(ReceiveAddr) == SOCKET_ERROR)

 {

   AfxBeginThread(conn,0);

   return 0

  }

  AfxBeginThread(连接后要进行的事务相关的线程,0);

  return 0;

}

....
如果断网，就启动conn线程
......

以上代码写的时候没管语法，你只要知道这个意思就行了
