Winsock Error 10042


It could also occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as "orphans"). This may indicate the file was deleted on the NFS server or some other catastrophic event occurred. WSA_QOS_EFILTERCOUNT 11021 Incorrect QoS filter count. Are you using an optional level or socket option that may not be supported on all WinSock implementations?

This is a generic error code, returned under various conditions. May 27 '10 #2 reply Expert Mod 5K+ P: 9,588 Frinavale Ok, this is an interesting problem. Note that this error is returned by the operating system, so the error number may change in future releases of Windows. 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

Socket Error 10054

This error may also be returned for protocol and service queries, and means the specified name could not be found in the relevant database.WSA_INVALID_HANDLE (OS dependent)Specified event object handle is invalid.An WSAEOPNOTSUPP (10045) Operation not supported. Berkeley description: A socket operation was attempted to an unreachable host.

Developer suggestion: are you trying to use an optional feature? 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 See other suggestions under WSAECONNABORTED. Socket Error Codes Linux Berkeley description: A connection was forcibly closed by a peer.

These conditions are more likely to be indicated by the error WSAETIMEDOUT.WSAEHOSTUNREACH (10065)No route to host.A socket operation was attempted to an unreachable host. Winsock Error 10053 This usually results from trying to connect to a service that is inactive on the foreign host. Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. WinSock functions: the list of functions that explicitly list this error in the v1.1 Windows Sockets specification.

A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the Winsock Error 10061 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. 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. WSAESOCKTNOSUPPORT (10044) Socket type not supported.

  1. WSA_QOS_BAD_OBJECT 11013 QoS bad object.
  2. A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied.
  3. Error Description List (0) No error WSABASEERR (10000) No error Berkeley Description: no equivalent.

This error occurs if you specifically reference a protocol that isn't part of the address family you also reference. Socket Error 10054 Advanced Search Forum Visual C++ & C++ Programming Network Programming Problems with multicast sockets in Windows If this is your first visit, be sure to check out the FAQ by clicking What Is A Socket Error The values for WSANO_DATA and WSANO_ADDRESS (11004) are duplicates, so we don't count one of them.

Developer suggestions: If you have a network analyzer available, you can quickly check if the destination port number and host address are what you expect. Check This Out This normally results if the peer program on the remote host is suddenly stopped, the host is rebooted, or the remote host used a "hard close" (see setsockopt for more information For instance, if the length of an argument which is a struct sockaddr is smaller than sizeof(struct sockaddr).WSAEHOSTDOWN (10064)Host is down.A socket operation failed because the destination host was down. Alternately, you can get the local IP address by calling gethostname() followed by gethostbyname(). Socket Error 10054 Connection Reset By Peer

WinSock description: Same as Berkeley, and then some. DimstateAsStateObject=CType(ar.AsyncState,StateObject) DimhandlerAsSocket=state.workSocket 'Readdatafromtheclientsocket. It is a non-fatal error, and the operation should be retried later. I can not locate a fix for this particular problem, there is a kludge which is to put a 5 - 10 second thread delay just before the BeginReceive call.

Check whether you have a router configured in your network system (your WinSock implementation). Socket Error 10061 Connection Refused Since the buffering requirements for sending are less than for receiving datagrams, it's conceivable that you can send a datagram larger than you can receive. Try a "traceroute" to the host you were connected to.

It may also make explicit mention of other functions that can fail with this error.

This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in Client programs usually need not call bind at all - connect will choose an unused port automatically.WSAEADDRNOTAVAIL (10049)Cannot assign requested address.The requested address is not valid in its context. The system detected an invalid pointer address in attempting to use a pointer argument of a call. Winsock Error Windows 7 WSAECONNREFUSED 10061 Connection refused.

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 WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application. Historical Number PRI5720 Product Alias/Synonym Fact winsock error messages Connect:Direct Windows All Releases 7.0.11932010.2834905 Goal FAQ: What are the meanings of the Winsock Error Codes? It also occurs with functions that take a socket handle and a sockaddr structure as input parameters.

WinSock description: No equivalent. User suggestions: Check the obvious first: check that the destination address is a valid IP address. WSAETIMEDOUT 10060 Connection timed out. WinSock description: Same as Berkeley.

A connect request was made on an already-connected socket. Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified? WSAESHUTDOWN 10058 Cannot send after socket shutdown. If you're wondering, I also tried including and (which solved the error for 'struct ip_mreq' not defined), then linking with ws2_32.lib and it also worked!!
