【网络编程】之七、select聊天室
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
好久沒有用MFC 來寫代碼了，手都生疏了，悲劇啊，好多API 都去查的 ?哎~~~
好了 下面把 我們聊天室的代碼貼出：
select函數(shù)封裝：
[cpp]?view plaincopy
BOOL?CserverDlg::Select_Server(SOCKET?sock,?int?nTime?,?BOOL?bRead?)?? {?? ????fd_set?fdset;?? ????timeval?tv;?? ????FD_ZERO(&fdset);?? ????FD_SET(sock,?&fdset);?? ????nTime?=?nTime?>?1000???1000?:?nTime;?? ????tv.tv_sec??=?0;?? ????tv.tv_usec?=?nTime;?? ?? ????int?iRet?=?0;?? ????if?(?bRead?)?{?? ????????iRet?=?select(0,?&fdset,?NULL?,?NULL,?&tv);?? ????}else{?? ????????iRet?=?select(0,?NULL?,?&fdset,?NULL,?&tv);?? ????}?? ?? ????if(iRet?<=?0)?{?? ????????return?FALSE;?? ????}?else?if?(FD_ISSET(sock,?&fdset)){?? ????????return?TRUE;?? ????}?? ????return?FALSE;?? }??
下面是線程函數(shù)，分別是服務(wù)器和客戶端的：
[cpp]?view plaincopy
static?UINT?__cdecl?ThreadProc(LPVOID?pParam);??
[cpp]?view plaincopy
UINT?CserverDlg::ThreadProc(LPVOID?lpParameter?)?? {?? ????ASSERT(lpParameter);?? ????CserverDlg?*lthis?=?(CserverDlg*)lpParameter;?? ????sockaddr_in?clientAddr?=?{0};?? ?? ????WSADATA?wsaData;?? ????WORD?sockVersion?=?MAKEWORD?(2,?0);?? ????::WSAStartup(sockVersion,?&wsaData);?? ?? ????lthis?->m_sSock?=?INVALID_SOCKET;?? ????lthis?->m_sSock?=?socket(AF_INET,?SOCK_STREAM,?IPPROTO_TCP);?? ????if?(lthis?->m_sSock?==?INVALID_SOCKET)?? ????{?? ????????AfxMessageBox("error");?? ????????::WSACleanup();?? ????????return?TRUE;?? ????}?? ?? ????sockaddr_in?ser;?? ????ser.sin_family?=?AF_INET;?? ????ser.sin_port?=?htons(8888);?? ????ser.sin_addr.S_un.S_addr?=?INADDR_ANY;?? ?? ????if?(::bind(lthis->m_sSock,?(LPSOCKADDR)&ser,?sizeof(ser))?==?SOCKET_ERROR)?? ????{?? ????????AfxMessageBox("error");?? ????????WSACleanup();?? ????????return?TRUE;?? ????}?? ?? ????if?(listen(lthis->m_sSock,?2)?==?SOCKET_ERROR)?? ????{?? ????????AfxMessageBox("error");?? ????????WSACleanup();?? ????????return?TRUE;?? ????}?? ?? ????int?nclientAddr?=?sizeof(clientAddr);?? ????lthis?->m_sClient?=?accept(lthis->m_sSock,?(SOCKADDR*)&clientAddr,?&nclientAddr);?? ????if?(lthis->m_sClient?==?INVALID_SOCKET)?? ????{?? ????????AfxMessageBox("error");?? ????????return?TRUE;?? ????}?? ?? ????while(TRUE)?? ????{?? ????????if?(lthis->Select_Server(lthis->m_sClient)?==?TRUE)?? ????????{?? ????????????TCHAR?recvMeg[1024]?=?{0};?? ?? ????????????int?re?=?recv(lthis->m_sClient,?(char*)recvMeg,?1024,?0);?? ????????????if?(re?>?0)?? ????????????{?? ????????????????recvMeg[re]?=?'\n';?? ????????????????lthis->recvMeg(recvMeg);?? ????????????}?? ????????????else?? ????????????{?? ????????????????lthis->recvMeg("客戶端下線");?? ????????????????break;?? ????????????}?? ????????}?? ????????Sleep(500);?? ????}?? ?? ????if?(lthis->m_sClient?!=?INVALID_SOCKET)?? ????{?? ????????closesocket(lthis->m_sClient);?? ????}?? ????if?(lthis->m_sSock?!=?INVALID_SOCKET)?? ????{?? ????????closesocket(lthis->m_sSock);?? ????}?? ?? ????WSACleanup();?? ????return?TRUE;?? }??

發(fā)送信息：
[cpp]?view plaincopy
