An attempt was made to access a socket in a way forbidden by its access permissions. Using Winsock Procedures and programming techniques used with Windows Sockets. WinSock functions: bind(), connect(), sendto(), socket(), FD_CONNECT See also: WSAEPROTOTYPE WSAEALREADY (10037) Operation already in progress. Ping a host on the same subnet as the host you were connected to (if you know one). news

This can also result from connect, sendto, WSAConnect, WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0). 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 For protocols and services resolution, it means the respective database wasn't located. For server applications that need to bind multiple sockets to the same port number, consider using setsockopt (SO_REUSEADDR). https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Berkeley description: A directory with entries other than `.'and `..' was supplied to a remove directory or rename call. See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> current community chat Stack Overflow Meta Stack Overflow your WSA_OPERATION_ABORTED 995 Overlapped operation aborted. They signal unusual error conditions for which there's no WinSock error equivalent.

  • a TCP reset received from remote host).
  • 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.
  • WSAEISCONN The socket is already connected (connection-oriented sockets only).
  • Developer suggestions: If you don't detect it beforehand (e.g.
  • Can you ping that hostname?
  • WinSock functions: See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAEHOSTUNREACH (10065) No route to host.
  • WSAEINVAL (10022) Invalid argument.
  • Are there any further levels of debug which I can use to understand this problem?         void CStrategy2View:nClient() {  bool bool1,bool2,bool3; int interr1,interr2,interr3; // TODO: Add your command handler code

A Winsock error code can be converted to an HRESULT for use in a remote procedure call (RPC) using HRESULT_FROM_WIN32. Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket) WSANOTINITIALISED 10093 Successful WSAStartup not yet performed. Socket Error 10061 Connection Refused WSAEINTR 10004 Interrupted function call.

Return value If no error occurs, connect returns zero. WSAENOTEMPTY 10066 Directory not empty. If socket s, is unbound, unique values are assigned to the local association by the system, and the socket is marked as bound. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740673(v=vs.85).aspx WSA_QOS_BAD_OBJECT 11013 QoS bad object.

A reserved policy element was found in the QoS provider-specific buffer.   Requirements Header Winsock2.h; Winerror.h See also Error Codes - errno, h_errno and WSAGetLastError Handling Winsock Errors FormatMessage WSAGetLastError   Windows Socket Error Windows 10 The name you have used is not an official hostname or alias. An unrecognized object was found in the QoS provider-specific buffer. The WSAGetLastError function returns the last error that occurred for the calling thread.

Socket Error 10054 Connection Reset By Peer

It may also make explicit mention of other functions that can fail with this error. https://msdn.microsoft.com/en-us/library/windows/desktop/ms737828(v=vs.85).aspx a long zero) in the sockaddr_in structure passed to sendto(). Socket Error Codes Linux WSAEAFNOSUPPORT Addresses in the specified family cannot be used with this socket. Winsock Error 10053 Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH.

Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. navigate to this website WSAEINVAL The parameter s is a listening socket. Error Codes - errno, h_errno and WSAGetLastError In Winsock applications, error codes are retrieved using the WSAGetLastError function, the Windows Sockets substitute for the Windows GetLastError function. For a connectionless socket (for example, type SOCK_DGRAM), the operation performed by connect is merely to establish a default destination address that can be used on subsequent send/ WSASend and recv/ Socket Error 11004

I realised there are 2 things I forgot to tell you:- 1. Berkeley description: A connection abort was caused internal to your host machine. Otherwise, the value SOCKET_ERROR (-1) is returned and a specific error number can be retrieved by calling the WSAGetLastError function. More about the author The specified socket parameter refers to a file, not a socket.

User suggestions: see WSAECONNABORTED for details. Socket Error 11001 When the communication does not work, we get an error (apparently while a process was trying to send data). There are some very serious drawbacks.

This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.

The only time a WinSock might use this error--at least with a TCP/IP implementation of WinSock--it fails a function with other errors (for example, WSAETIMEDOUT). WSAETIMEDOUT An attempt to connect timed out without establishing a connection. If so, treat this as a non-fatal error and ignore it, if possible. Wsagetlasterror 0 User suggestions: see WSAHOST_NOT_FOUND for details.

We appreciate your feedback. Return code/valueDescription WSA_INVALID_HANDLE 6 Specified event object handle is invalid. In this section TopicDescription What's New for Windows Sockets Information on new features for Windows Sockets. click site So, for example, you can expect this error if a WinSock implementation doesn't support socket type SOCK_RAW within the Internet address family (AF_INET).

WSAENOPROTOOPT (10042) Bad protocol option. WSAEPROTONOSUPPORT 10043 Protocol not supported. WSAECONNABORTED 10053 Software caused connection abort. after failed calls to inet_addr() or gethostbyname()), then simply test your address value for zero before you pass it to sendto().

Berkeley description: An address incompatible with the requested protocol was used. With Winsock, programmers are provided access to advanced Microsoft® Windows® networking capabilities such as multicast and Quality of Service (QoS). Berkeley description: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket) no address was supplied. An invalid or inconsistent flowspec was found in the QoS provider-specific buffer.

User suggestions: Try to ping the destination host, to see if you get the same results (chances are, you will). This is what occurs in Berkeley Sockets. This is a common problem.
