  2. Additional functions: Any functions that takes a pointer as an input parameter: inet_addr(), inet_ntoa(), ioctlsocket(), gethostbyaddr(), gethostbyname(), getservbyname(), getservbyport(), WSAAsyncGetHostByName(), WSAAsyncGetHostByAddr(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber, WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSASetBlockingHook() WSAEHOSTDOWN (10064) Host is down.
  3. This could be due to an out of memory error or to an internal QoS provider error.
  4. WSAENETDOWN 10050 Network is down.

Any function that takes a socket as an input parameter--except close socket()--could potentially fail with this error. this content It could also occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as "orphans"). This error occurs if you specifically reference a protocol that isn't part of the address family you also reference. Detailed description: select(): fails with WSAENOTSOCK if any socket in an fd_set is an invalid socket handle. Socket Error 10049

Socket Error 10061 Connection Refused Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations.

I've tested it on three desktops, two running XP and the other running Win7, I've also tested it on four laptops, three running Win7 and one running XP. An unrecognized object was found in the QoS provider-specific buffer. WSAGetLastError() The next step was to set up a socket. check over here Windows Sockets 2 added functions and features with other Windows Sockets error codes returned in addition to those listed in the original Winsock specification.

WSAESOCKTNOSUPPORT 10044 Socket type not supported. WSA_E_NO_MORE 10110 No more results. Ignore it. Developer suggestions: Always check the return value from a memory allocation to be sure it succeeded.

WSAEISCONN 10056 Socket is already connected. An invalid policy object was found in the QoS provider-specific buffer. Do not set non-zero timeout on non-blocking sockets to avoid this ambiguity (see Chapter 9 for more information). Additional functions: a generic description of the type of functions that can return this error, which may include functions other than those listed by the WinSock specification.

Is there a way to load the ShowConfig before Sitecore finishes initializing? It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. The specified file handle is not a valid file-handle value or does not refer to an open file; or an attempt was made to write to a file or device opened Typically, though, WinSock generates this error when it receives a "host unreachable" ICMP message from a router.

I have found theses on a similar subject to my own, and want to use their references with my own text and a similar flow.
