WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), See also: WSAHOST_NOT_FOUND, WSANO_RECOVERY, WSATRY_AGAIN WSANO_RECOVERY (11003) This is a non-recoverable error Berkeley description: This is a Berkeley description: A pathname lookup involved more than 8 symbolic links. the byte-order functions, htonl(), htons(), ntohl and ntohl(), cannot fail. An operation was attempted on something that is not a socket.

User suggestions: Did you enter a destination hostname? Calls to WSAStartup() and WSACleanup() must be balanced at all times. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. OS dependentWSA_NOT_ENOUGH_MEMORYInsufficient memory available.

here is the server code: Code: #include #include #include #include int ListenOnPort(int portno); int main() { int errorcode=0; printf("Hello world!\n"); // while(1) errorcode=ListenOnPort(6221); printf("errorcode is %d", errorcode); So, quitting (the application) at the first sign of trouble may not be the answer. An error with the underlying traffic control (TC) API as the generic QoS request was converted for local enforcement by the TC API. For server applications that need to bind multiple sockets to the same port number, consider using setsockopt (SO_REUSEADDR).

A general QoS error. 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. Is it possible to have a planet unsuitable for agriculture? The application has tried to determine the status of an overlapped operation which is not yet completed.

WinSock description: Unlike Berkeley Sockets, in WinSock WSAEALREADY means that the asynchronous operation you attempted to cancel has already been canceled. Some error codes defined in the Winsock2.h header file are not returned from any function. I found a great tut (Programming Windows TCP Sockets in C++ for the Beginner - CodeProject) but everything did not work as aspected. Again we can modify our code (slightly) to display why socket creation has failed.

This error is also possible on a datagram socket; for instance, this error could result if your application sends a UDP datagram to a host, which rejects it by responding with So, for example, you can expect this error if a WinSock implementation doesn't support socket type SOCK_RAW within the Internet address family (AF_INET). asked 4 years ago viewed 9058 times active 4 years ago Related 2bluetooth winsock error 10049 on connect()0Winsock connect() hanging on one network, but not another0c++ winsock client cannot connect using WinSock functions: send(), sendto(), setsockopt() Additional functions: Any function that does network I/O: recv(), recvfrom(), FD_READ, FD_WRITE See also: WSAECONNABORTED, WSAECONNRESET, WSAETIMEDOUT WSAENETUNREACH (10051) Network is unreachable.

you tried to connect to the wrong destination host address the server application isn't running on the destination host the server application isn't listening on the right port. Networking activity on the local host has not been initiated. WSANOTINITIALISED 10093 Successful WSAStartup not yet performed. This is just a style recommendation.

As we pointed out earlier, your application should be ready to encounter any error at any time. Clearly, this oversight was not intentional. See WSAENETUNREACH. If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.

If it is not valid we can use WSAGetLastError() to find what has gone amiss. Developer suggestions: Things an application developer can do to avoid the error. User suggestions: Check your WinSock, protocol stack, network driver and network interface card configuration. Basically, you want to identify where the problem occurred.

I read online that this error caused by not calling WSAStartup() but I did called it in the socket's constructor and it did accept in the first time. User suggestions: Check that you have a name server(s) and/or host table configured. Dev centers Windows Office Visual Studio Microsoft Azure More...

Any application that uses a blocking socket or calls any blocking functions must handle this error. If so, is there an older DLL in a directory in the path ahead of the directory containing the newer DLL?

Just bind() it to INADDR_ANY to listen on all available interfaces (including the loopback). An invalid QoS filter type was used. This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto().

The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending." If the local host sent any more data WinSock functions: With a datastream socket: connect() and FD_CONNECT WSAAsyncelect() notification message. The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below).

WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available. This usually results from trying to connect to a service that is inactive on the foreign host.

The file's permission setting does not allow the specified access. An established connection was aborted by the software in your host machine, possibly due to a data transmission time-out or protocol error. 10054WSAECONNRESETConnection reset by peer.

This could happen with a call to another function later, including connect, listen, WSAConnect, or WSAJoinLeaf. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid.
