Winsock Errors


A call to the WSALookupServiceEnd function was made while this call was still processing. When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call. WSA_QOS_POLICY_FAILURE 11011 QoS policy failure. WinSock description: Same as Berkeley. Check This Out

However, there's little distinction between WSAEALREADY and WSAEINVAL since a WinSock DLL cannot tell the difference between an asynchronous operation that has been cancelled and one that was never valid. WinSock description: Partly the same as Berkeley. For inet_addr(), this could mean the content of the buffer passed or the buffer itself is invalid. You closed this socket (by a call to closesocket), and still try to use it.

Winsock Error Windows 7

If you used a hostname, did it resolve to the correct address? SO_ACCEPTCONN, SO_ERROR, SO_TYPE: are read-only options, so they work with getsockopt(), but not with setsockopt() Developer suggestions: Check the parameters. I graduated from Emory University in Atlanta, GA in 2002 with a degree in Computer Science and Mathematics.

WSAECONNABORTED 10053 Software caused connection abort. Note that this error is returned by the operating system, so the error number may change in future releases of Windows.

If it doesn't respond, it might be off-line or there may be a network problem along the way. Socket Error 10049 Although the specification doesn't list an error for a function, it does allow for it. WSA_QOS_GENERIC_ERROR 11015 QoS generic error. WSAGetLastError() and WSAIsBlocking() cannot fail.

  1. WSAENETDOWN 10050 Network is down.
  2. This is not a soft error, another type of name server request may be successful.
  3. No connection could be made because the target computer actively refused it.
  4. a long zero) in the sockaddr_in structure passed to sendto().
  5. With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion).
  6. The WSAAsyncSelect() FD_WRITE event is specifically designed to notify an application after a WSAEWOULDBLOCK error when buffer space is available again so send() or sendto() should succeed.
  7. send() or sendto(): out of buffer space, so try again later or wait until FD_WRITE notification (WSAAsyncSelect()) or select() writefds is set.

Thirteen errors have "" next to the list of WinSock functions that can produce them. his comment is here WinSock description: Almost same as Berkeley. User suggestions: Check the obvious first: check that the destination address is a valid IP address. If an error occured during this process, mostly the program will report as winsock error. Socket Error 11004

Developer suggestions: You need to be prepared to handle this error on any functions that reference blocking sockets, or any calls to blocking functions, if you allow the user to cancel doesn't reference a valid socket). User suggestions: see WSAECONNABORTED for details. this contact form WSAECONNREFUSED 10061 Connection refused.

Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH. Winsock Error Windows 10 Typically, only one usage of each socket address (protocol/IP address/port) is permitted. This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous.

It also has a specific meaning for setsockopt().

An application used a Windows Sockets function that directly maps to a Windows function. WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available. If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. How To Fix Socket Error The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for.

User suggestions: Try to ping the destination host, to see if you get the same results (chances are, you will). Is the router up and running (check by pinging it, and then ping an address on the other side of it)? A blocking operation is currently executing. navigate here Detailed descriptions: connect(): the operation is underway, but as yet incomplete.

WinSock functions: getsockopt(), setsockopt() Additional functions: Bad IP headers can cause routers and remote hosts to issue ICMP "parameter problem" messages, which result in a ENOPROTOOPT error on Berkeley-derived systems. Berkeley description: An operation that takes a long time to complete (such as a connect()) was attempted on a non-blocking socket. (see ioctl()). See also: WSAECONNABORTED, WSAENETRESET, WSAETIMEDOUT WSAEDESTADDRREQ (10039) Destination address required.

A Windows Sockets implementation may have a limit on the number of applications that can use it simultaneously. WSAENOBUFS 10055 No buffer space available. Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call. The FormatMessage function can be used to obtain the message string for the returned error.

You may also attempt to uninstall and then reinstall the program that uses Winsock file. 5. This is the one. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. In this case, the 2nd application will fail with WSAEADDRINUSE.

Berkeley description: A write to an ordinary file, the creation of a directory or symbolic link, or the creation of a directory entry failed because the user's quota of disk blocks Berkeley description: An operation was attempted on a non-blocking object that already had an operation in progress. It might be that the Winsock error you are seeing is actually a virus pretending to be error. 3. Detailed descriptions: the specific meanings that some WinSock functions have for some errors.

Software firewall also checks signature of the program, so if you do an update, you need to create a new rule or update your rule for the new version. There are several ways to fix the problem: using the command line, downloading a third party app, etc. 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
