Windows Sockets Version 2 Api Error Code
If you are using a host table exclusively, you'll need to update it to add the destination hostname and address. If so, then the application might have had a problem resolving the name (see suggestions at WSATRY_AGAIN for more information). What is an instant of time? Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP. get redirected here
User suggestions: Did you enter a destination hostname? In fact, on occasion you can benefit if the WinSock implementation returns these other errors. Usually this occurs when a file descriptor refers to a file or socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

WSANO_DATA (11004) Valid name, no data record of requested type Berkeley description: The requested name is valid, but does not have an Internet IP address at the name server. WSAHOST_NOT_FOUND 11001 Host not found. WSA_QOS_EPSFLOWSPEC 11027 Invalid QoS provider-specific flowspec.
- Use the Poll method to determine when the Socket is finished connecting. From http://msdn2.microsoft.com/en-us/library/ych8bz3x(vs.80).aspx Wednesday, July 25, 2007 4:41 AM Reply | Quote 0 Sign in to vote
- Return value The return value indicates the error code for this thread's last Windows Sockets operation that failed.
- WSAEPROTOTYPE 10041 Protocol wrong type for socket.
- WSA_QOS_SENDERS 11006 QoS senders.
- 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
- Output Drift of an operational Integrator Why does Wolfram Alpha say the roots of a cubic involve square roots of negative numbers, when all three roots are real?
- WinSock functions: getsockopt(), setsockopt() Additional functions: Bad IP headers can cause routers and remote hosts to issue ICMP "parameter problem" messages, which result in a ENOPROTOOPT error on Berkeley-derived systems.
I know that this is a problem with the adress name but don't see whats the problem. Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. The file handle reference is no longer available. Winsock Error 10061 These errors might be reported on any function that does network I/O (e.g.
So in Winsock applications the WSAEWOULDBLOCK error code would be returned, while in UNIX applications the EWOULDBLOCK error code would be returned. Socket Error 10054 Connection Reset By Peer Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application. WSAEISCONN (10056) Socket is already connected.
WSAEADDRNOTAVAIL 10049 Cannot assign requested address. Windows Socket Error Windows 10 We suggest local configuration changes that might remedy the problem, and network and server conditions that might be the cause. WSAEMFILE 10024 Too many open files. For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr).
Socket Error 10054 Connection Reset By Peer
An error with the underlying traffic control (TC) API as the generic QoS request was converted for local enforcement by the TC API. WSAEACCES 10013 Permission denied. Socket Error Codes Linux WinSock functions: listen(), FD_CONNECT Additional functions: connect(), sendto() WSAELOOP (10062) Too many levels of symbolic links. Socket Error 10053 WSAECONNREFUSED 10061 Connection refused.
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. Get More Info By calling shutdown() you do a partial close of a socket, which means you have discontinued sending. However, there's little distinction between WSAEALREADY and WSAEINVAL since a WinSock DLL cannot tell the difference between an asynchronous operation that has been cancelled and one that was never valid. WinSock description: Same as Berkeley. Socket Error 11004
WinSock functions: getpeername(), recv(), recvfrom(), send(), sendto(), setsockopt(), shutdown(), FD_CONNECT See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAENOTEMPTY (10066) Directory not empty. You can avoid making the mistake of trying to send on a socket after you've initiated a close, by keeping track of the socket state in your application (and checking it Unfortunately, the same error occurs over and over again for a while (a few minutes). useful reference 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

Winsock Error Windows 7 Is the router up and running (check by pinging it, and then ping an address on the other side of it)? Developer suggestions: Since there're only one corresponding protocol for each of the datagram and datastream socket types in the Internet address family, you should simply leave the value in the protocol
WinSock description: No equivalent.
Windows Phone 8: This function is supported for Windows Phone Store apps on Windows Phone 8 and later. Privacy statement Dev Centers Windows Office More... 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. Winsock Error 10054 Fix WinSock description: Similar to Berkeley.
This extended error code can be different from the error code obtained from getsockopt when called with an optname parameter of SO_ERROR, which is socket-specific since WSAGetLastError is for all thread-specific This is what occurs in Berkeley Sockets. The "address" they refer to, typically refers to the local "socket name", which is made up of the 3-tuple: protocol, port-number and IP address. this page Maximum server memory Transposition of first matrix in crossprod in R Is it required that I upgrade to Sierra more hot questions question feed lang-cpp about us tour help blog chat
recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is It's also possible that the local services file has an incorrect port number (although it's unlikely). Check whether you have a router configured in your network system (your WinSock implementation). Functionless Errors There are a total of fifty unique WinSock error values.
Check your WinSock implementation documentation to be sure all necessary components are currently installed and configured correctly. WinSock description: Same as Berkeley. Developer suggestions: If you don't detect it beforehand (e.g. An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.
For Winsock functions that return a handle, a return value of INVALID_SOCKET (0xffff) indicates an error and a specific error number can be retrieved by calling WSAGetLastError. WinSock functions:
SO_ACCEPTCONN, SO_ERROR, SO_TYPE: are read-only options, so they work with getsockopt(), but not with setsockopt() Developer suggestions: Check the parameters. If a source file includes code which inspects errno for both socket and non-socket functions, this mechanism cannot be used. Berkeley description: A protocol was specified that does not support the semantics of the socket type requested. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER.
