This error occurs if you specifically reference a protocol that isn't part of the address family you also reference. It could also occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as "orphans"). This may indicate the file was deleted on the NFS server or some other catastrophic event occurred. They signal unusual error conditions for which there's no WinSock error equivalent.

In some instances, it also refers to the current state of the socket—for instance, calling accept on a socket that is not listening. Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address. Any application that uses a blocking socket or calls any blocking functions must handle this error. Functionless Errors There are a total of fifty unique WinSock error values.

Socket Error 10054

The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections. It is also possible that WinSock might return this error after an application calls connect() a second time on a non-blocking socket while the connection is pending (i.e. WinSock functions: recv(), recvfrom(), send(), sendto(), with datastream sockets only. WinSock description: Same as Berkeley.

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 This is what occurs in Berkeley Sockets. For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr).

What if this fails for some reason? WSANO_RECOVERY 11003 This is a nonrecoverable error. and other countries. WinSock description: Same as Berkeley.

Any function that takes a socket as an input parameter--except close socket()--could potentially fail with this error. Wsagetlasterror 0 Is the router up and running (check by pinging it, and then ping an address on the other side of it)? This error is returned by the WSCGetProviderInfo and WSCGetProviderInfo32 functions if the protocol entry specified could not be found. It is a nonfatal error, and the operation should be retried later.

What Is A Socket Error

WinSock description: a quick comparison to the Berkeley counterpart, and a long description of WinSock error. WinSock description: Same as Berkeley. Socket Error 10054 The occurrence of an unlisted error can provide extra detail. Socket Error 10053 WinSock functions: WSACancelAsyncRequest() Additional functions: Berkeley sockets connect() returns this error on subsequent calls, after an initial call on a non-blocking socket.

Berkeley description: Normally results from an attempt to create a socket with an address not on this machine. Berkeley description: A connection was forcibly closed by a peer. the protocol stack that the WinSock DLL runs over). User suggestions: Some network systems have commands to report statistics. Socket Error 10054 Connection Reset By Peer

  • A completion indication will be given later when the operation has been completed.
  • Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (for SOCK_STREAM sockets, the to parameter in sendto is ignored) although other implementations treat this as
  • WSA_QOS_EFLOWDESC 11026 Invalid QoS flow descriptor.
  • WSAETIMEDOUT 10060 Connection timed out.
  • WinSock description: No equivalent.
  • The attempted operation is not supported for the type of object referenced.
  • The "address" it refers to is the remote socket name (protocol, port and address).
  • An application attempts to use an event object, but the specified handle is not valid.
  • The WSAAsyncSelect() FD_WRITE event is specifically designed to notify an application after a WSAEWOULDBLOCK error when buffer space is available again so send() or sendto() should succeed.

He also lurks around the forums as Hieran_Del8. WSAEMFILE 10024 Too many open files. The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete. An unknown, invalid or unsupported option or level was specified in a getsockopt or setsockopt call.

This is usually caused by one or more of the function pointers being NULL. Wsaeconnreset 10054 In fact, on occasion you can benefit if the WinSock implementation returns these other errors. WinSock functions: socket() See also: WSAEAFNOSUPPORT, WSAEPFNOSUPPORT WSAEREMOTE (10071) Too many levels of remote in path Berkeley description: Item is not local to the host.

Berkeley description: A component of a path name exceeded 255 (MAXNAMELEN) characters, or an entire path name exceeded 1023 (MAXPATHLEN-1) characters.

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 The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. We will explore UDP in later tutorials. Socket Error 11004 Some errors do not always mean death for the program.

This documentation is archived and is not being maintained. The Windows Sockets API does not have analogs for the Berkeley perror() and herror() functions that take the error value as input, and output the (short) text of each error value Among other things, that is exactly what we've done here. Note that this error is returned by the operating system, so the error number may change in future releases of Windows.

WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: It seems odd that the v1.1 specification doesn't ascribe this error to the function bind(). WSAEBADF (10009) Bad file descriptor. This usually means the local software knows no route to reach the remote host. Instead, let the network system assign the local port (very few application protocols require a client to bind to a specific port number or port number range).

An invalid or unrecognized service type was found in the QoS flowspec. Don't believe me? It may also indicate you are not closing the applications properly. WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available.
