Winsok Error

Contents

It is an Application program interface (API) which acts as a connecting bridge between an application program for internet such as your browser and Windows operating system. 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. User suggestions: Things an application user can do to diagnose the error condition further, and/or remedy it. However, it is interchangeable in most cases, and all Windows Sockets functions that return one of these messages also specify WSAEAFNOSUPPORT.

The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. You should simply ignore this error when it occurs. WSA_QOS_EFILTERCOUNT 11021 Incorrect QoS filter count. This documentation is archived and is not being maintained.

Winsock Error Windows 7

Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH. WinSock description: Almost same as Berkeley. WSAECONNREFUSED 10061 Connection refused. WSA_QOS_RECEIVERS 11005 QoS receivers.

WSAEREMOTE (10071) Too many levels of remote in path Item is not local to the host. An unrecognized object was found in the QoS provider-specific buffer. Returned when a system call that should never fail does fail. What Is A Socket Error Apparently, the Windows Sockets specification left this out by oversight.

WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), See also: WSAHOST_NOT_FOUND, WSANO_DATA, WSATRY_AGAIN WSASYSNOTREADY (10091) Network subsystem is unavailable Berkeley description: No equivalent. On the server end, you could use a network system utility similar to BSD's "netstat -a" command to check that your server is running, and listening on the right port number. Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e. https://msdn.microsoft.com/en-us/library/windows/desktop/cc507522(v=vs.85).aspx Network problem.

Alternately, you could call getprotobyname() or WSAAsyncGetProtoByName() to get the appropriate protocol value from the network system. Socket Error 10049 The specified socket parameter refers to a file, not a socket.WSAEDESTADDRREQ (10039) Destination address required A required address was omitted from an operation on a socket. Usually this occurs when a socket descriptor to a socket that cannot support this operation is trying to accept a connection on a datagram socket. WinSock description: Same as Berkeley, and then some.

WSAEOPNOTSUPP 10045 Operation not supported. http://www.kanasolution.com/products/dyndns-updater/dyndns-faqs/what-is-winsock-error-and-how-can-i-fix-it/ 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 Windows 7 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. Winsock Error 10061 Latest software firewall has an ability to create automatic rule.

WinSock functions: socket() See also: WSAEPROTOTYPE, WSAEPROTONOSUPPORT WSAESTALE (10070) Stale NFS file handle. WinSock functions: listen(), FD_CONNECT Additional functions: connect(), sendto() WSAELOOP (10062) Too many levels of symbolic links. The FormatMessage function can be used to obtain the message string for the returned error. WSAESHUTDOWN 10058 Cannot send after socket shutdown. Winsock Error 10053

SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM. For example, you can try to ping the server(s). No more results can be returned by the WSALookupServiceNext function. Networking activity on the local host has not been initiated.

Subsequent operations fail with WSAECONNRESET. Socket Error 10054 Connection Reset By Peer WSAEDISCON 10101 Graceful shutdown in progress. Berkeley description: A connection was forcibly closed by a peer.

A system call that should never fail has failed.

WSANO_DATA (11004)* Valid name, no data record of requested type The requested name is valid, but does not have an Internet IP address at the name server. WinSock description: No equivalent. Note: If driver’s update caused Winsock error to happen, reverse the updates to old version. 6. Winsock Error 10060 WinSock description: No error.

An invalid QoS provider-specific buffer. There's at least one WinSock implementation that will occasionally fail a function and report this as the error value, even though the function succeeded. WSA_OPERATION_ABORTED 995 Overlapped operation aborted. WinSock functions: Any function capable of a blocking operation can return this error: accept(), close socket(), connect(),gethostbyname(), gethostbyaddr(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), recv(), recvfrom(), select(), send(), sendto() Additional functions: Any of

Thirteen errors have "" next to the list of WinSock functions that can produce them. Since Windows Sockets is practically a clone of Berkeley Sockets, and the rule of thumb is "when in doubt, defer to Berkeley", we can adopt the Berkeley Software Distribution error text
