WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object.

Winsock Error Windows 7

This would occur if WinSock aborts an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket). 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 There are no QoS senders.

The option is unknown or unsupported.WSAEPROTONOSUPPORT (10043) Protocol not supported The protocol has not been configured into the system, or no implementation for it exists. Developer suggestions: Always check the return value from a memory allocation to be sure it succeeded. WSAENOTCONN (10057) Socket is not connected A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket) no address was What Is A Socket Error The following list describes the possible error codes returned by the WSAGetLastError function.

WSAENOTEMPTY 10066 Directory not empty. Winsock Error 10054 Berkeley description: An operation on a socket or pipe was not performed because the system lacked sufficient buffer space or because a queue was full. WSAEINVALIDPROCTABLE 10104 Procedure call table is invalid. https://msdn.microsoft.com/en-us/library/ms832261.aspx Berkeley description: No connection could be made because the target machine actively refused it.

In some cases these errors are platform dependent. Socket Error 10049 See WSASYSNOTREADY for details. Try a traceroute to the destination address to check that all the routers are functioning. A protocol was specified in the socket function call that does not support the semantics of the socket type requested.

Winsock Error Windows 7 This message has a slightly different meaning from WSAEAFNOSUPPORT. Winsock Error 10053 Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e.

WinSock description: Same as Berkeley; the option is unknown or unsupported. With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). WSANOTINITIALISED (10093) Successful WSASTARTUP not yet performed Either your application hasn't called WSAStartup, or WSAStartup failed. weblink See also: WSAEAFNOSUPPORT WSAEPROCLIM (10067) Too many processes.

Error Message: WINSOCK Error: Socket is not connected. Socket Error 10054 Connection Reset By Peer If it doesn't respond, it might be off-line or there may be a network problem along the way. 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.

Detailed description: recv() and recvfrom(): if the datagram you read is larger than the buffer you supplied, then WinSock truncates the datagram (i.e.

The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. There's at least one WinSock implementation that will occasionally fail a function and report this as the error value, even though the function succeeded. Berkeley description: A socket operation failed because the destination host was down. Socket Error Codes Linux 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.

The service cannot be found in the specified name space. The ICMP message means that the router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down). Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket) check over here NOTE: The MAKEWORD macro referenced in the code fragment is not available in the WINSOCK.H header file or in any standard header files.

Is the router up and running (check by pinging it, and then ping an address on the other side of it)? The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. WSA_QOS_EFILTERSTYLE 11019 Invalid QoS filter style. A name component or a name was too long.
