Windows Sockets Version 2 Api Error Code Documentation


If the application is using WSAAsyncSelect to indicate interest in connection events, then the application will receive an FD_CONNECT notification indicating that the connect operation is complete (successfully or not). Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections. Either the application has not called WSAStartup or WSAStartup failed. get redirected here

The default destination can be changed by simply calling connect again, even if the socket is already connected. 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. Handling Winsock Errors Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns. WSA_QOS_EFILTERSTYLE 11019 Invalid QoS filter style. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Socket Error Codes Linux

The WinSock API does not provide access to the Network File System application protocol, so this error is irrelevant to WinSock. Check your subnet mask. Berkeley description: An operation was attempted on a non-blocking object that already had an operation in progress. TCP/IP scenario: Most WinSock implementations use domain name system (DNS) protocol for hostname to address resolution, although a few use Network Information System (NIS).

  • For protocol and services resolution, the name or number was not found in the respective database.
  • For WinSock, this error is equivalent to Berkeley's EHOSTUNREACH error, the catch-all error for unreachable hosts. "You can't get there from here." TCP/IP scenario: The local network system could generate this
  • This normally results if the peer application on the remote host is suddenly stopped, the host is rebooted, the host or remote network interface is disabled, or the remote host uses
  • Additional functions: With a datagram socket: send() or sendto(), or FD_READ.

Too many links were encountered in translating a pathname. So, as far as I understand, the connection was interrupted by the receiving process. By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving, or both have been discontinued. Socket Error 10061 Connection Refused User suggestions: Check that you have a name server(s) and/or host table configured.

WSA_QOS_EFILTERCOUNT 11021 Incorrect QoS filter count. User suggestions: see WSAHOST_NOT_FOUND for details. I dont know how much difference this makes? Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you!

Does error10035 indicate a fault at the connect end and how can this be avoided.? Windows Socket Error Windows 10 Notice that asynchronous service and protocols functions are listed below, in addition to the hostname resolution functions. A protocol was specified in the socket function call that does not support the semantics of the socket type requested. Developer suggestion: are you trying to use an optional feature?

Socket Error 10054 Connection Reset By Peer

For compatibility with BSD, an application may choose to change the Winsock2.h and uncomment this block. https://msdn.microsoft.com/en-us/library/windows/desktop/ms737828(v=vs.85).aspx WSAECONNREFUSED The attempt to connect was forcefully rejected. Socket Error Codes Linux WSAEAFNOSUPPORT (10047) Address family not supported by protocol family. Winsock Error 10053 This documentation is archived and is not being maintained.

Detailed descriptions: the specific meanings that some WinSock functions have for some errors. Get More Info WinSock functions: WSAEWOULDBLOCK (10035) Resource temporarily unavailable. send() & sendto(): socket not bound (for Dgram) or not yet connected (for Stream) The v1.1 specification also has a detailed description for the connect() function which says: "socket not already The socket input parameter is not a valid socket handle (either it never was valid, it's a file handle (not a socket handle), or if it was a socket handle, it Socket Error 11004

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 For connection-oriented, nonblocking sockets, it is often not possible to complete the connection immediately. WSA_QOS_EFLOWSPEC 11017 QoS flowspec error. http://pubdimensions.com/socket-error/windows-socket-version-2-api-error-code-documentation-in-msdn.php This will verify that the destination network is functioning.

Socket Error 11001 Try for debugging the value 0. –rekire Jun 12 '12 at 14:26 add a comment| up vote 0 down vote I was facing this problem for some days recently and found Specifically, these error-less functions are the byte order functions ( htonl(), htons(), ntohl(), and ntohs()), the address manipulation functions (inet_addr(), and inet_ntoa), WSAGetLastError() and WSAIsBlocking().

In this case, there are three possible scenarios: Use the select function to determine the completion of the connection request by checking to see if the socket is writeable.

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: No error. The error codes returned by Windows Sockets are similar to UNIX socket error code constants, but the constants are all prefixed with WSA. Wsagetlasterror 0 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.

An application used a Windows Sockets function that directly maps to a Windows function. Try a "traceroute" to the host you were connected to. This documentation is archived and is not being maintained. this page Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions.

For example, if a call to WaitForMultipleEvents fails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs. Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below. See also: These point to other errors that are similar. This normally results from a loss of the connection on the remote socket due to a timeout or a reboot.

There are no QoS receivers. If the error code returned indicates the connection attempt failed (that is, WSAECONNREFUSED, WSAENETUNREACH, WSAETIMEDOUT) the application can call connect again for the same socket. Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call. 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.

User suggestions: Some network systems have commands to report statistics. Note that the v1.1 WinSock specification does not explicitly state that this error occurs if the value you request is larger than the WSAData.iMaxUdpDg returned from WSAStartup(). WinSock functions: WSAESHUTDOWN (10058) Cannot send after socket shutdown. WSAENOBUFS 10055 No buffer space available.

WSAESTALE 10070 Stale file handle reference. The WinSock implementation was unable to allocate additional memory to accommodate the function request. Detailed description: recv() and recvfrom(): if the datagram you read is larger than the buffer you supplied, then WinSock truncates the datagram (i.e. Microsoft C description: Bad file number.

Issuing another blocking Winsock call inside an APC that interrupted an ongoing blocking Winsock call on the same thread will lead to undefined behavior, and must never be attempted by Winsock If an application developer insists on using the BSD error codes for compatibility, then an application may choose to include a line of the form: C++ Copy #include #define errno Can indicate a service provider implementation error.
