Seasonal Challenge (Contributions from TeXing Dead Welcome) Is there a reason why housekeeping wouldn't accept a tip? Have you tried closing and reestablishing the connection in the loop? See also: These point to other errors that are similar. An object with an invalid ObjectLength field was specified in the QoS provider-specific buffer. have a peek at this web-site

Winsock functions: bind(), connect(), listen(), FD_CONNECT WSAEADDRNOTAVAIL (10049) Cannot assign requested address. WinSock functions: See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAEHOSTUNREACH (10065) No route to host. WinSock description: Partly the same as Berkeley. Here is an example of using select: fd_set fds; timeval tv; tv.tv_sec = 5000; fds.fd_count = 1; fds.fd_array[0] = ClientSocket; int select_result = select(1, &fds, NULL, NULL, &tv); If select_result == https://msdn.microsoft.com/en-us/library/windows/desktop/ms740121(v=vs.85).aspx

Recv C++

Messages from other addresses are (silently) discarded. This could indicate a serious failure of the network system (that is, the protocol stack that the Windows Sockets DLL runs over), the network interface, or the local network itself. An error with the underlying traffic control (TC) API as the generic QoS request was converted for local enforcement by the TC API. WinSock functions: send(), sendto() Additional functions: setsockopt() and any function that takes a socket (or file handle) as an input parameter.

This is what occurs in Berkeley Sockets. Identify a short story about post-apocalyptic household robots C++11 - typeid uniqueness `patch:instead` removes an element with no attributes Why didn’t Japan attack the West Coast of the United States during A connect request was made on an already-connected socket. Recv Timeout But that's not to say you shouldn't still be prepared.

WSAENOPROTOOPT (10042) Bad protocol option. Winsock Select A existing connection was forcibly closed by the remote host. Like always, you find your error when you try to explain it for someone else :) I leave it up to the reader to figure out what was wrong, but I'll SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM.

Not implemented: name server does not perform specified operation. Winsock Send This has no network-relevant analog (although the "inode" reference could refer to a network file system entry). Developer suggestions: for protocols and services consider using a hard-coded value for the protocol number or service port number in case your resolution attempt fails, and you can have your cake The value of WSAGetLastError() is 10060 –Nicolas Miranda Saavedra Sep 26 '13 at 13:45 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted The server

  • Please look at code: #include #include int main() { WSADATA winsock_data; WSAStartup (MAKEWORD (2, 0), &winsock_data); SOCKET socket_body; socket_body = socket (PF_INET, 1, 0); struct timeval to; to.tv_sec =
  • For example, the error can occur when an attempt is made to read from a file that is not open, to open an existing read-only file for writing, or to open
  • WinSock description: Same as Berkeley.
  • The occurrence of an unlisted error can provide extra detail.
  • An invalid QoS filter type was used.
  • If I comment out the reinterpret_cast line and use the line below it works!
  • WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable.
  • Assuming you have a name server configured instead of or as well as a host table, a hostname resolution request causes a WinSock DLL to send a DNS "A" record query
  • The WinSock implementation will not allow you to send after this.
  • Developers should consider handling the referenced errors similarly.

Winsock Select

Berkeley description: A required address was omitted from an operation on a socket. WSAEDQUOT 10069 Disk quota exceeded. Recv C++ User suggestions: Try to ping the destination host, to see if you get the same results (chances are, you will). Recv Example WinSock description: Same as Berkeley, and then some.

WSAGetLastError() and WSAIsBlocking() cannot fail. Check This Out WSAENOTCONN The socket is not connected. If so, treat this as a non-fatal error and ignore it, if possible. An application used a Windows Sockets function that directly maps to a Windows function. Recv Vs Read

This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server. WSAENETRESET 10052 Network dropped connection on reset. The WSAGetLastError function returns the last error that occurred for the calling thread. Source WSAECONNREFUSED 10061 Connection refused.

WinSock functions: gethostbyaddr(), gethostbyname(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() Additional functions: It is strange that the asynchronous protocol and services functions can fail with this error, but the synchronous cannot. Recv Msg_peek An address incompatible with the requested protocol was used. Now I am making complete guesses here...

Whether to handle it as a fatal error or non-fatal error depends on the application and the context, so it's entirely up to you to decide.

WSAEISCONN 10056 Socket is already connected. This 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. An invalid or unrecognized service type was found in the QoS flowspec. Recv Function In Socket Programming In C Developer suggestion: are you trying to use an optional feature?

Show: Inherited Protected Print Export (0) Print Export (0) Share IN THIS ARTICLE Is this page helpful? WinSock functions: WSAEUSERS (10068) Too many users. An invalid FILTERSPEC was found in the QoS provider-specific buffer. http://nbxcorp.com/winsock-error/winsock-error-183.html MSG_WAITALLThe receive request will complete only when one of the following events occurs: The buffer supplied by the caller is completely full.

The only function that takes these two explicit parameters is socket(). flags [in] A set of flags that influences the behavior of this function. WinSock description: Same as Berkeley. WinSock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other

Covered by US Patent. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. If you don't have the proper subnet mask, your network system may treat a local address as a remote address (so it forwards addresses on the local subnet to the router, WSAEINTR (10004) Interrupted function call.

If it does respond, then this problem might have been a transient one (so you can reconnect now), or the server application you were connected to might have terminated (so you c++ sockets winsock share|improve this question asked Jul 12 '13 at 20:32 GilAlexander 312 In your while loop you should break if n > 0, that way you can Do a traceroute to try to determine where the failure occurs along the route between your host and the destination host. char recvBuff[DEFAULT_BUFLEN]; int recvBuffLen = DEFAULT_BUFLEN; int iSendResult; //Server/Client sockets.

When the program calls the recv Winsock function, you receive this error code http://support.microsoft.com/kb/925513 share|improve this answer answered Jun 21 '14 at 17:16 Faisal 28416 I understand the reason
