Winsock Error After Reconnection


This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto(). The v1.1 WinSock specification only ascribes thirty-three of the fifty errors to any of the WinSock functions in the v1.1 for Windows Sockets specification. Winsock functions: bind(), connect(), listen(), FD_CONNECT WSAEADDRNOTAVAIL (10049) Cannot assign requested address. Any help regarding this would be greatly appreciated. Check This Out

WinSock description: Same as Berkeley, except WinSock doesn't support the sendmsg() function, and some WinSock implementations are not so strict as to require an application with a datagram socket to "disconnect"--by If you used a hostname, did it resolve to the correct address? 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 Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call.

If so, is there an older DLL in a directory in the path ahead of the directory containing the newer DLL? WinSock description: Same as Berkeley. Check the destination address you are using.

  1. recv(), recvfrom(), send(), sendto(): MSG_OOB was specified, but the socket is not of type SOCK_STREAM Developer suggestions: don't do that.

  3. For more information on debugging problems, see Chapter 13, "Debugging." Errorless Functions Eight of the forty-six functions in the Windows Sockets API are not referenced in any of the "WinSock function"
  4. 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(),
  5. Check the destination address you are using.
  6. Clearly, this oversight was not intentional.
  7. For instance, this error will occur if you try to run two applications that have FTP servers that both try to accept connections on port 21 (the standard FTP port).

Note: this error may also result if you try to send a multicast packet and the default gateway does not support multicast (check your interface configuration). Request refused: Name server refuses to satisfy your query for policy reasons. WinSock description: The current WinSock implementation does not support the Windows Sockets specification version requested by the application.

Socket Error Codes Linux TCP, UDP, ICMP, ARP, DNS) that typically causes the error. An application attempted an input/output network function call before establishing an association with a remote socket (i.e. No more file handles are available, so no more files can be opened.

Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function. Winsock Error Windows 7 See WSASYSNOTREADY for details. On the Clients a message is sent via winsock to the server, containing a bitstring, amongst other things, to the server.

Failing Module.......................... So, for example, if a Winsock implementation doesn't support SOCK_RAW with IPPROTO_IP (or any other protocol), then the socket call would fail with WSAEPROTONOSUPPORT (however, if it doesn't support SOCK_RAW at Tcp Socket Error

Developer suggestions: Handle this as a non-fatal error. You would need to update your Winsock to a supported version. WinSock description: The Windows Sockets definition of this error is very different from Berkeley. this contact form WSAEBADF (10009) Bad file descriptor.

Why can I use P = I²R but not P=V²/R when calculating energy lost in a circuit? Windows Socket Error 10054 a long zero) in the sockaddr_in structure passed to sendto().

The Winsock API does not provide any way to select specific name resolution protocols, server address, or record type. It means that there is a blocking operation outstanding.It is also possible that Winsock might return this error after an application calls connect a second time on a non-blocking socket while 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. http://isusaa.org/socket-error/winsock-error-10049.php WinSock description: Same as Berkeley, and then some.

What amount of samples to use? WSANO_DATA (11004)* Valid name, no data record of requested type The requested name is valid, but does not have an Internet IP address at the name server. Why increase the number of cylinders in an engine instead of increasing their volume? By calling shutdown() you do a partial close of a socket, which means you have discontinued sending.

WinSock functions: Additional functions: If a WinSock implementation has an upper limit to the number of simultaneous tasks it can handle, an application's initial call to WSAStartup() could fail with Why? I'm sure I've done that before! –Martin James Sep 29 '14 at 10:49 @MartinJames how did you manage to do that? –Awais Chishti Sep 29 '14 at 11:41 WinSock functions: accept(), close socket(), connect(), recv(), recvfrom(), send(), sendto(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() WSAHOST_NOT_FOUND (11001) Host not found Berkeley description: No such host is known.
