The Data Source Name (DSN) may be incorrect. WSATRY_AGAIN 11002 Nonauthoritative host not found. WinSock description: No equivalent. SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM. news

Refresh the page to continue. WSA_QOS_EOBJLENGTH 11022 Invalid QoS object length. User suggestions: Check that the WINSOCK.DLL file is in the current path Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack. TransmitPackets?

WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available"). WSAEPROCLIM 10067 Too many processes. A system call that should never fail has failed. If the signal handler performs a normal return, the interrupted function call will seem to have returned the error condition.

Every error description contains at least: Summary Info: Error macro: manifest constant, as defined in WINSOCK.H Error value: as defined in v1.1 WINSOCK.H Short description Berkeley description: text describing the equivalent Developer suggestions: Handle this as a non-fatal error. You might have gone to the wrong host, or the server application you are trying to contact might not be running. Socket Error 11004 Detailed descriptions: connect(): the operation is underway, but as yet incomplete.

Developer suggestion: The simple suggestion is "don't do that." No matter what value you use for the "how" parameter to the shutdown() function, you cannot send afterwards. Socket Error 10053 Usually this occurs when a socket descriptor to a socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. WinSock description: Unlike Berkeley Sockets, in WinSock WSAEALREADY means that the asynchronous operation you attempted to cancel has already been canceled. https://technet.microsoft.com/en-us/library/cc975854.aspx WINSOCK Error: Can't send after socket shutdown....

You could also try to resolve another hostname you know should work, to check that the name resolution server application is running. Winsock Error 10054 Fix An invalid QoS filter type was used. Explanation: No connection could be made because the target computer actively refused it. 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.

Socket Error 10053

WSAEPROTONOSUPPORT (10043) Protocol not supported. The requested protocol has not been configured into the system, or no implementation for it exists. https://bobobobo.wordpress.com/2009/02/02/getting-winsock-error-messages-in-string-format/ Developers should consider handling the referenced errors similarly. Socket Error Codes Linux Yes No Do you like the page design? Socket Error 10054 Connection Reset By Peer User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O.

HTTP Server could not create the main connection thread. navigate to this website Any application that uses a blocking socket or calls any blocking functions must handle this error. The server was unable to add the virtual root ' name ' for the directory ' ... Otherwise, you may need to cast instead to LPWSTR, depending on the settings in your Visual Studio project. –Camille Goudeseune Sep 20 '14 at 20:40 I edited the answer Socket Error 10049

This message indicates that the key (name, address, and so on) was not found. The data is er... WSAENOBUFS (10055) No buffer space available. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. http://jactionscripters.com/socket-error/winsock-error-997.php WinSock description: Same as Berkeley; the option is unknown or unsupported.

Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. Winsock Error 10061 It is a nonfatal error, and the operation should be retried later. WSANO_RECOVERY (11003) This is a non-recoverable error. This indicates some sort of non-recoverable error occurred during a database lookup.

However, some WinSocks fail with WSAEINVAL you call connect() a second time (or subsequent) on a non-blocking socket.

  1. A service provider returned a bogus procedure table to Ws2_32.dll.
  2. WSAELOOP 10062 Too many levels of symbolic links.
  3. Notice that asynchronous service and protocols functions are listed below, in addition to the hostname resolution functions.
  4. Berkeley description: A connect or send request failed because the connected party did not properly respond after a period of time. (The timeout period is dependent on the communication protocol.) WinSock
  5. You can avoid making the mistake of trying to send on a socket after you've initiated a close, by keeping track of the socket state in your application (and checking it
  6. WSAEINVAL 10022 Invalid argument.
  7. WinSock description: Same as Berkeley, and then some.
  8. WSA_IO_PENDING (OS dependent) Overlapped operations will complete later. The application has initiated an overlapped operation which cannot be completed immediately.
  9. WSAENOTSOCK 10038 Socket operation on nonsocket.

The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). 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, Specifically, v1.1 WinSock spec notes that this error occurs if the length of the buffer is too small. Socket Error 10061 Connection Refused recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is

send() and sendto(): you cannot send a datagram as large as you've requested. TCP/IP scenario: description of the TCP/IP protocol suite network traffic (i.e. WSAESHUTDOWN 10058 Cannot send after socket shutdown. http://jactionscripters.com/socket-error/winsock-2-0-error.php If so, then the application might have had a problem resolving the name (see suggestions at WSATRY_AGAIN for more information).

The attempted operation is not supported for the type of object referenced. Please try again later.... Top Of Page Show: Inherited Protected Print Export (0) Print Export (0) Share IN THIS ARTICLE Is this page helpful? try to ping the server(s)).

The application has tried to determine the status of an overlapped operation which is not yet completed. This may be because the database files (for example, BSD-compatible HOSTS, SERVICES, or PROTOCOLS files) could not be found, or a DNS request was returned by the server with a severe WSA_NOT_ENOUGH_MEMORY Insufficient memory available WSA_OPERATION_ABORTED Overlapped operation aborted WSA_IO_INCOMPLETE Overlapped I/O object not signalled WSA_IO_PENDING Overlapped I/O will complete later WSA_INVALID_PARAMETER One or more parameters are invalid WSA_INVALID_HANDLE Event object handle

Developer suggestions: to make your application more portable: with datagram sockets don't use connect() and sendto() on the same datagram socket in an application, and always "disconnect" before calling connect() more Failed to save document.... An invalid or unrecognized service type was found in the QoS flowspec. For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency.

May also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed. So, for example, if a WinSock implementation doesn't support SOCK_RAW with IPPROTO_IP (or any other protocol), then the socket() call would fail with WSAEPROTONOSUPPORT (however, if it doesn't support SOCK_RAW at WINSOCK Error: Bad protocol option.... A socket operation encountered a dead network.
