See also: WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAECONNREFUSED (10061) Connection refused. This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. we don't recommend it). The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. http://jactionscripters.com/socket-error/windows-socket-version-2-api-error-code-documentation.php

WinSock functions: WSAENOTSOCK (10038) Socket operation on non-socket. before calling connect() or accept()). Subsequent operations fail with WSAECONNRESET. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Socket Error Codes Linux

No such service is known. For example, the value given for the origin when positioning a file pointer (by means of a call to fseek) is before the beginning of the file. The file handle supplied is not valid.

However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error. WinSock functions: recv(), recvfrom(), send(), sendto(), FD_CLOSE Additional functions: Any function that does I/O on the network could generate this error. A couple functions that the v1.1 specification missed are WSASetLastError() and WSAUnhookBlockingHook(). Socket Error 10061 Connection Refused Error codeMeaning WSANOTINITIALISED A successful WSAStartup call must occur before using this function.

On a blocking socket, the return value indicates success or failure of the connection attempt. WSAEINTR (10004) Interrupted function call.

So there was a new server process running and listening on the correct port, but the client had not detected this and was still trying to use the old connection. Windows Socket Error Windows 10 The "address" they refer to, typically refers to the local "socket name", which is made up of the 3-tuple: protocol, port-number and IP address. A socket operation was attempted to an unreachable host. For more information on debugging problems, see Chapter 13, "Debugging." Errorless Functions Eight of the forty-six functions in the Windows Sockets API are not referenced in any of the "WinSock function"

Socket Error 10054 Connection Reset By Peer

When the success or failure outcome becomes known, it may be reported in one of two ways, depending on how the client registers for notification. https://msdn.microsoft.com/en-us/library/windows/desktop/ms737828(v=vs.85).aspx Winsock functions: bind(), connect(), listen(), FD_CONNECT WSAEADDRNOTAVAIL (10049) Cannot assign requested address. Socket Error Codes Linux A specific address needs to be implicitly bound by the connect function. Winsock Error 10053 The errors that have User suggestions are all the same ones in the "User-fixable errors" list above.

For example, new name service functions (getaddrinfo and getnameinfo, for example) were added that support both IPv6 and IPv4 on Windows XP and later. weblink The occurrence of an unlisted error can provide extra detail. TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending." If the local host sent any more data Developer suggestions: Since there're only one corresponding protocol for each of the datagram and datastream socket types in the Internet address family, you should simply leave the value in the protocol Socket Error 11004

  • WSA_E_CANCELLED 10111 Call was canceled.
  • This usually results from trying to connect to a service that is inactive on the foreign host.
  • This error is also returned if the sockaddr structure pointed to by the name parameter with a length specified in the namelen parameter is not in a valid part of the
  • TCP/IP scenario: In BSD-compatible implementations, the local network system generates this error if there isn't a default route configured.
  • Can you ping that hostname?
  • WSAEISCONN (10056) Socket is already connected.
  • WinSock functions: accept(), close socket(), connect(), recv(), recvfrom(), send(), sendto(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() WSAHOST_NOT_FOUND (11001) Host not found Berkeley description: No such host is known.
  • WSAENETRESET 10052 Network dropped connection on reset.
  • WinSock description: Same as Berkeley, and then some.
  • There are only a few possible causes for this error: you tried to connect to the wrong port.

WinSock functions: WSAEWOULDBLOCK (10035) Resource temporarily unavailable. For example, if a call to WaitForMultipleEvents fails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs. An incorrect number of QoS FILTERSPECs were specified in the FLOWDESCRIPTOR. navigate here try to ping the server(s)).

WSANOTINITIALISED 10093 Successful WSAStartup not yet performed. Socket Error 11001 WinSock description: Same as Berkeley. In Berkeley, this error also occurs when you are trying to name the local socket (assign local address and port number) with bind(), but Windows Sockets doesn't ascribe this error to

See also: WSAEAFNOSUPPORT WSAEPROCLIM (10067) Too many processes.

An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable. An invalid QoS filter type was used. The call has been canceled. Wsagetlasterror 0 For protocols and services resolution, it means the respective database wasn't located.

Check that no old Windows Sockets DLL files are being accessed. Berkeley description: A file descriptor argument was out of range, referred to no open file, or a read (write) request was made to a file that was only open for writing The error codes returned by Windows Sockets are similar to UNIX socket error code constants, but the constants are all prefixed with WSA. his comment is here WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable.

If the client uses the select function, success is reported in the writefds set and failure is reported in the exceptfds set. TCP, UDP, ICMP, ARP, DNS) that typically causes the error. A connection attempt failed because the connected party did not properly respond after a period of time, or the established connection failed because the connected host has failed to respond. If not, check with your WinSock vendor to see if they have a newer WinSock available.

The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below). Then, the default remote address will be indeterminate, so send/ WSASend and recv/ WSARecv calls will return the error code WSAENOTCONN. WSA_QOS_NO_RECEIVERS 11008 QoS no receivers. 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,

A database query failed because it was actively refused. The standard meaning for WSAEINVAL applies to connect() (invalid argument). It's also possible that the local services file has an incorrect port number (although it's unlikely). Too many links were encountered in translating a pathname.

WSAESTALE 10070 Stale file handle reference. 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 WinSock description: Partly the same as Berkeley. Windows Sockets 2 Purpose Windows Sockets 2 (Winsock) enables programmers to create advanced Internet, intranet, and other network-capable applications to transmit application data across the wire, independent of the network protocol

For example, the error can occur when an attempt is made to read from a file that is not open, to open an existing read-only file for writing, or to open Developer suggestion: Use the sample code fragment in the WSAStartup() documentation in the v1.1 specification, which demonstrates how an application negotiates a Windows Sockets specification version. This error usually occurs when executing bind, but could be delayed until the connect function if the bind was to a wildcard address (INADDR_ANY or in6addr_any) for the local IP address. Is it required that I upgrade to Sierra Coding Standard - haphazard application Where will the second Fantastic Beasts film be set?

connect function The connect function establishes a connection to a specified socket. The "address" it refers to is the remote socket name (protocol, port and address). Networking activity on the local host has not been initiated. Some Winsock functions return a value of zero if successful.
