10035 Socket Error

Desktop Development > C++ Standards, Extensions, and Interop Question 0 Sign in to vote I am getting Error 10035 wsa error 10054 after issuing Connect. The Create method on the connect socket is winsock 10051 successful. Create and Listen on the Listening Socket are successful , the computerid and port parameters are correct and

are set to "loopback" and 4000, which work OK on a similar program which is a Dialog application rather than an MDI application. The OnAccept event is not issued

on the Listening Socket and so the connection is not completed. Does error10035 indicate a fault at the connect end and how can this be avoided.? If not, what is wrong at the Listen end? Are there any further levels of debug which I can use to understand this problem? void CStrategy2View:nClient() { bool socket error 10061 bool1,bool2,bool3; int interr1,interr2,interr3; // TODO: Add your command handler code here interr1 = 0; ConfigDlg.DoModal(); bool1=ConnectSocket.Create(); interr1 = ConnectSocket.GetLastError(); interr2 = 0; bool2 = ConnectSocket.Connect(ConfigDlg.m_computerid,ConfigDlg.port); interr2 = ConnectSocket.GetLastError(); Client = TRUE; } void CStrategy2View:nServer() { // TODO: Add your command handler code here bool bool1,bool2; int interr1,interr2; bool1 = ListenSocket.Create(ConfigDlg.port); interr1 = GetLastError(); bool2 = ListenSocket.Listen(); interr2 = GetLastError(); Client = FALSE; } Tuesday, July 24, 2007 5:30 PM Reply | Quote All replies 0 Sign in to vote Error 10035 is described as: WSAEWOULDBLOCK10035 A non-blocking socket operation could not be completed immediately. What this means is the operation would normally be a blocked operation (i.e would only return when completed) but is operating in a non blocking mode, thus it did not have time to complete. Check out The Connect method will block, unless you specifically set the Blocking property to false prior to calling Connect. If you are using a connection-oriented protocol like TCP and you do disable blocking, Connect will throw a SocketException because it needs time to make the connection. Connectionless protocols will not throw an exception because they simply establish a defau

Are you sure you succeed as making the socket non-blocking? –unwind Jun 12 '13 at 11:20 1 You get WSAEWOULDBLOCK on a non-blocking socket if there is currently no data available. That is normal behaviour. –Martin R Jun 12 '13 at 11:24 add a comment| 1 Answer 1 active oldest votes up vote 7 down vote accepted This is normal if no data is available. The code is WSAEWOULDBLOCK (see this table) and means, that on a blocking port the function would have to sit and wait until it could be served. while(1) { if((recv_len = recvfrom(newSocketIdentifier, receiveBuffer, sizeof(receiveBuffer), 0, (struct sockaddr *) &clientSocket, &clientSocketLength)) == SOCKET_ERROR) { int ierr= WSAGetLastError(); if (ierr==WSAEWOULDBLOC
error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. It is a nonfatal error, and the operation https://bobobobo.wordpress.com/2008/11/09/resolving-winsock-error-10035-wsaewouldblock/ should be retried later. It is normal for WSAEWOULDBLOCK to be reported as http://cboard.cprogramming.com/networking-device-communication/146857-how-solve-error-number-10035-a.html the result from calling connect on a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established. WTF??? wtf indeed This error isn't an error at all. Pay attention to the last phrase: 10035: WSAEWOULDBLOCK. Resource temporarily unavailable. This error is returned from operations on nonblocking sockets that cannot be completed socket error immediately, for example recv when no data is queued to be read from the socket. It is a nonfatal error, and the operation should be retried later. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established. In a program, like that crummy msdn example, I wrote: // 10035 socket error Connect to server. if ( connect( g.s, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) { int err = WSAGetLastError(); printf( "Failed to connect: Error code: %d.\n", err ); WSACleanup(); return; } But what would happen EVERY TIME is 10035: WSAEWOULDBLOCK. WHY??? I puzzled over this again and again. WHAT IS WSAEWOULDBLOCK?? codegear has: Abstract: Whenever I try to run my socket program, I get the error WSAEWOULDBLOCK. Question Why do I get a WSAEWOULDBLOCK error when I run my program. Answer This means that you are setting up your program as a non-blocking sockets program, however the computer is telling you that it would have to create a blocked connection to the socket. Of all the bullshit… THAT DOESN'T ANSWER MY QUESTION!! So, I tried putting it in a loop to see if the state would change: // Connect to server. while ( connect( g.s, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) { int err = WSAGetLastError(); printf( "Failed to connect: Error code: %d.\n", err ); //WSACleanup(); //return; } INTERESTINGLY, this is what happens: 10035 10056 10056 10056 10056 10056 10056 10056 . . . Where 10056 is: 10056: WSAEISCONN Socket is already connected. A connect request was made on an already-connected socket. So

I write two programsne is to send data,another is to receive data,and I register a message function,Look: Code: WSAAsyncSelect(m_sock,m_hWnd,WM_RNET,FD_READ); void CTcpFSDlg::OnRNet(WPARAM wParam,LPARAM lParam) { char recvbuf[100]; int retval,err; while(1) { retval=recv((SOCKET)wParam,recvbuf,100,0); if(retval==SOCKET_ERROR) { err=WSAGetLastError(); str.Format("recv error=%d",err); MessageBox(str); break; } MessageBox(recvbuf); } } when I send one message,this program can receive it,but it receive a error number 10035,when I send more than one message, I only receive the first message and error number 10035, I want to know how to solve it? 03-16-2012 #2 stahta01 View Profile View Forum Posts Registered User Join Date May 2009 Posts 3,015 Windows Sockets Error Codes WSAEWOULDBLOCK 10035 Resource temporarily unavailable.
