Winsock2 Error Codes

This error is returned if any Windows Sockets API function is called while a blocking function is in progress. Thanks again Remy. –StackTrace May 8 '12 at 10:27 11031 is 0x2B17 and 76567 is 0x12B17. Some WinSock implementation use these errors inappropriately, but they have a particular meaning. if(url.find("http://") == 0) url.erase(0, 7); // Get the host name. http://itechnologysolutionsllc.com/socket-error/winsock2-error.php

You are unlikely to encounter them. You can verify that the remote system is rejecting your connection attempt by checking the network statistics locally. WSAEADDRINUSE 10048 Address already in use. you're trying to share a socket between tasks). you can try this out

Socket Error Codes Linux

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. Either the application has not called WSAStartup or WSAStartup failed. The QoS request was rejected because the policy system couldn't allocate the requested resource within the existing policy. For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM.

  1. You will notice from the documentation that this means "The name parameter is not a valid part of the user address space." I would check what hst.c_str() is returning.
  2. If you have more than one server configured, the hostname query fails only after the WinSock DLL has queried all servers.
  3. For this tutorial we will be working with the final code used back in tutorial 2 (the blocking server).
  4. WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available").
  5. Error codes set by Windows Sockets are not made available through the errno variable.
  6. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections.
  7. all other functions: retry the operation again later since it cannot be satisfied at this time.

WinSock functions: WSACancelAsyncRequest() Additional functions: Berkeley sockets connect() returns this error on subsequent calls, after an initial call on a non-blocking socket. The requested address is not valid in its context. Other information varies between different errors. Socket Error 11004 If a source file includes code which inspects errno for both socket and non-socket functions, this mechanism cannot be used.

It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. Socket Error 10053 WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application. Such exclusive access is a new feature of Windows NT 4.0 with SP4 and later, and is implemented by using the SO_EXCLUSIVEADDRUSE option. anchor Note that this error is returned by the operating system, so the error number may change in future releases of Windows.

Some of the older IPv4-only name service functions (the getXbyY class of functions, for example) have been deprecated. Winsock Error 10061 A call to the WSALookupServiceEnd function was made while this call was still processing. So, if we run the application it will report the following error in our console. The address manipulation functions, inet_ntoa() andinet_addr(), can fail.

Socket Error 10053

An application attempted an input/output network function call before establishing an association with a remote socket (i.e. http://www.sockets.com/err_lst1.htm WinSock description: Same as Berkeley. Socket Error Codes Linux WinSock description: Same as Berkeley. Socket Error 10054 Connection Reset By Peer Too many open sockets.

User suggestions: Don't try running two of the same types of server applications on the same machine. http://itechnologysolutionsllc.com/socket-error/windows-tcp-ip-error-codes.php WSA_QOS_EFLOWDESC 11026 Invalid QoS flow descriptor. WSA_QOS_ESERVICETYPE 11016 QoS service type error. 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. Socket Error 10049

Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset. Is there any way to bring an egg to its natural state (not boiled) after you cook it? I discovered this while debugging a TransmitPackets problem that seemed quite random. http://itechnologysolutionsllc.com/socket-error/wsa-error-codes.php I've tested it on three desktops, two running XP and the other running Win7, I've also tested it on four laptops, three running Win7 and one running XP.

You need to call htons() to translate a constant value to network byte order before assigning it to the sin_port field in the sockaddr structure. Winsock Error 10054 Fix For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol. Each implementation may have a maximum number of socket handles available, either globally, per process, or per thread.

Detailed description: 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.

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. Can you ping that hostname? Berkeley description: A connection was forcibly closed by a peer. Socket Error 10061 Connection Refused Not the answer you're looking for?

Ping a host on the same subnet as the host you were connected to (if you know one). WSA_E_CANCELLED 10111 Call was canceled. How common is it to use the word 'bitch' for a female dog? Check This Out User suggestions: Check that you have a name server(s) and/or host table configured.

The X86 and X64 chips normally tolerate misaligned structures with a small performance penalty, but operating system calls such as TransmitPackets often do not. An invalid policy object was found in the QoS provider-specific buffer. This is what occurs in Berkeley Sockets. Generically, the error means the network system has run out of socket handles.

Again we can modify our code (slightly) to display why socket creation has failed. 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
