WSAEOPNOTSUPP (10045) Operation not supported. The attempted operation is not supported for the type of object referenced. See also: These point to other errors that are similar. The only time a WinSock might use this error--at least with a TCP/IP implementation of WinSock--it fails a function with other errors (for example, WSAETIMEDOUT). WSAEBADF 10009 File handle is not valid. navigate to this website

By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving, or both have been discontinued. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. WinSock description: Same as Berkeley, and then some. Any of the WinSock name resolution functions can fail with this error.

Socket Error Codes Linux

WSA_QOS_TRAFFIC_CTRL_ERROR 11014 QoS traffic control error. No more file handles are available, so no more files can be opened. Cannot remove a directory that is not empty.

  1. WinSock functions: Any function that takes a socket as an input parameter: accept(), bind(), closesocket(), connect(), getpeername(), getsockname(), getsockopt(), ioctl socket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), FD_CONNECT Additional
  2. WSAEFAULT (10014) Bad address. The system detected an invalid pointer address in attempting to use a pointer argument of a call.
  3. Functionless Errors There are a total of fifty unique WinSock error values.
  4. No connection could be made because the target computer actively refused it.
  5. User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O.
  6. WSA_INVALID_PARAMETER (OS dependent) One or more parameters are invalid. An application used a Windows Sockets function which directly maps to a Win32 function.
  7. Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call.
  8. Subsequent operations fail with WSAECONNRESET.

WSA_INVALID_HANDLE (OS dependent) Specified event object handle is invalid. An application attempts to use an event object, but the specified handle is not valid. You could also try to resolve another hostname you know should work, to check that the name resolution server application is running. WSAEPFNOSUPPORT 10046 Protocol family not supported. Socket Error 10049 Winsock functions: bind(), connect(), listen(), FD_CONNECT WSAEADDRNOTAVAIL (10049) Cannot assign requested address.

WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object. Socket Error 10054 Connection Reset By Peer Developer suggestion: are you trying to use an optional feature? For example, the optional type SOCK_RAW might be selected in a socket call, and the implementation does not support SOCK_RAW sockets at all. User suggestions: Check the obvious first: check that the destination address is a valid IP address.

Returned when a system call that should never fail does fail. Socket Error 11004 Berkeley description: A message sent on a socket was larger than the internal message buffer or some other network limit. 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). WinSock description: No equivalent WinSock functions: WSAEMFILE (10024) Too many open files.

Socket Error 10054 Connection Reset By Peer

The error can occur when the local network system aborts a connection. http://stackoverflow.com/questions/3400922/how-do-i-retrieve-an-error-string-from-wsagetlasterror Subscribe Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus About Mark Kaelin Mark W. Socket Error Codes Linux Check the destination address you are using. Windows Socket Error Windows 10 int sock = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP ) ; if( sock == SOCKET_ERROR ) { // Uh oh!

WinSock functions: WSAETIMEDOUT (10060) Connection timed out. The occurrence of an unlisted error can provide extra detail. Socket Error 10053

It is a non-fatal error, and the operation should be retried later. WSAENOPROTOOPT 10042 Protocol not available/bad protocol option. WinSock description: Same as Berkeley. my review here This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server.

An invalid QoS provider-specific buffer. Winsock Error Windows 7 A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied. Every error description contains at least: Summary Info: Error macro: manifest constant, as defined in WINSOCK.H Error value: as defined in v1.1 WINSOCK.H Short description Berkeley description: text describing the equivalent

WSAELOOP 10062 Too many levels of symbolic links.

With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). Here is a useable macro: #define MAKEWORD(low, high) ((WORD)(((BYTE)(low)) | (((WORD)((BYTE)(high))) << 8))) WinSock functions: WSAStartup(). [Go to Top] Errors in Numerical Order WSABASEERR (0) No Error WSAEINTR (10004) Interrupted system The values for WSANO_DATA and WSANO_ADDRESS (11004) are duplicates, so we don't count one of them. Winsock Error 10054 Fix User suggestions: Don't try running two of the same types of server applications on the same machine.

WinSock functions: accept(), bind(), closesocket(), connect(), gethostbyaddr(), gethostbyname(), gethostname(), getpeername(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), getsockname(), getsockopt(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e. WSAEINTR 10004 Interrupted function call. http://pdctoday.com/socket-error/windows-socket-error-on-api.php For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency.

WSAEPROTOTYPE 10041 Protocol wrong type for socket. The Win32 function is indicating a lack of required memory resources. WSAENOTCONN 10057 Socket is not connected. An attempt was made to access a socket in a way forbidden by its access permissions.

WSA_QOS_GENERIC_ERROR 11015 QoS generic error. You can monitor available memory with Program Manager's "Help/About..." command. User suggestions: Did you enter a destination hostname? Oh no! // whatever will winsock do?

The protocol family has not been configured into the system or no implementation for it exists. A socket operation failed because the destination host is down. Berkeley description: The host you were connected to crashed and rebooted. User suggestions: see WSAHOST_NOT_FOUND for details.
