Windows Sockets Error Codes


Too many references to some kernel object. The occurrence of an unlisted error can provide extra detail. Detailed descriptions (relevant to socket states): accept(): listen() was not invoked prior to accept() bind(): socket already bound to an address getsockname(): socket not bound with bind() listen(): socket not bound Additional functions: a generic description of the type of functions that can return this error, which may include functions other than those listed by the WinSock specification. news

It is beyond the scope of this specification to mandate a particular set of semantics for out-of-band data handling. WinSock functions: WSAEWOULDBLOCK (10035) Resource temporarily unavailable. WinSock description: Same as Berkeley. User suggestions: Check the obvious first: check that the destination address is a valid IP address. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Socket Error 10054 Connection Reset By Peer

This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. I used his .RTF file as the source file for this document. The simplest method is for the intermediate DLL to have calls similiar to WSAStartup() and WSACleanup() that applications call as appropriate.

  1. Microsoft C description: Bad file number.
  2. An existing connection was forcibly closed by the remote host.
  3. Privacy Policy Terms Disclaimer

Check the destination address you are using. In this case, the application may wish to determine whether any of the unread data is "urgent" (the term usually applied to in-line out-of-band data). This error apparently also takes the place of WSAEPFNOSUPPORT (which means "protocol family not supported"), since that error is not listed for socket() in the v1.1 WinSock specification. Winsock Error 10054 Fix Such a DLL could be used by several applications simultaneously, and the DLL must take special precautions with respect to the WSAStartup() and WSACleanup() calls to ensure that these routines are

WinSock description: Same as Berkeley, and then some. Socket Error Codes Linux The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. On the server end, you could use a network system utility similar to BSD's "netstat -a" command to check that your server is running, and listening on the right port number. Detailed description: select(): fails with WSAENOTSOCK if any socket in an fd_set is an invalid socket handle.

For example, this error is returned if sendto is called with the remote address of ADDR_ANY. Socket Error 11004 We appreciate your feedback. WinSock description: Unlike Berkeley Sockets, in WinSock WSAEALREADY means that the asynchronous operation you attempted to cancel has already been canceled. An example of a symmetric protocol is the TELNET protocol used in the Internet for remote terminal emulation.

Socket Error Codes Linux

getprotobynumber()* Retrieve the protocol name and number corresponding to a protocol number. You can verify that the remote system is rejecting your connection attempt by checking the network statistics locally. Socket Error 10054 Connection Reset By Peer Networking activity on the local host has not been initiated. Socket Error 10053 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

Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions. navigate to this website Imperatives of derivatives of facere, dicere and ducere email etiquette adding people to the thread vs reaching out directly Why is this C++ code faster than assembly? Closing a socket in one thread that has an outstanding blocking call on the same socket in another thread will cause the blocking call to fail with WSAEINTR, just as if SO_OOBINLINE BOOL Out-of-band data is FALSE being received in the normal data stream. Socket Error 10049

WinSock description: Either your application hasn't called WSAStartup(), or WSAStartup() failed, or--possibly--you are accessing a socket which the current active task does not own (i.e. Database Files The getXbyY() and WSAAsyncGetXByY() classes of routines are provided for retrieving network specific information. 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 More about the author Note that this error is returned by the operating system, so the error number may change in future releases of Windows.

Either the application has not called WSAStartup or WSAStartup failed. Windows Socket Error Windows 10 Socket descriptors are not presumed to correspond to regular file handles, and file operations such as read(), write(), and close() cannot be assumed to work correctly when applied to socket descriptors.. This normally results from an attempt to bind to an address that is not valid for the local computer.

This could be due to an out of memory error or to an internal QoS provider error.

This may indicate the file was deleted on the NFS server or some other catastrophic event occurred. Any recv() call on the remote side of the circuit can fail with WSAECONNRESET. In it's place, WinSock uses the error WSAENETUNREACH, exclusively. Socket Error 10061 Connection Refused WinSock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other

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 usually means the local software knows no route to reach the remote host. WSAENOTSOCK The descriptor is not a socket. click site We now have a mechanism to detect such situations and reset the connection on the client side.
