For example, the value given for the origin when positioning a file pointer (by means of a call to fseek) is before the beginning of the file.WSAEMFILE (10024) Too many open A couple functions that the v1.1 specification missed are WSASetLastError() and WSAUnhookBlockingHook(). WSAHOST_NOT_FOUND 11001 Host not found. However, some WinSocks fail with WSAEINVAL you call connect() a second time (or subsequent) on a non-blocking socket.
Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. Check that your network system (WinSock implementation) has a utility that shows network statistics. WinSock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other The v1.1 specification also lists connect(), although it does not allocate a descriptor.
Why "smashed avocado" rather than "mashed avocado"? WinSock functions: accept(), bind(), connect(), listen(), send(), sendto(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), FD_CONNECT Additional functions: Any other functions that use network system buffer space, like the "database functions", Simple methods to quickly fix Winsock Error 10004, Error -107 error message?
The QoS request was rejected because the policy system couldn't allocate the requested resource within the existing policy. WinSock functions: gethostbyaddr(), gethostbyname(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() Additional functions: It is strange that the asynchronous protocol and services functions can fail with this error, but the synchronous cannot. 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 Socket Error 11004 Note: What is Winsock Error 10004, Error -107 error?
Which is the error we intended to get, with our little test. Socket Error 10049 The only function that takes these two explicit parameters is socket.WSAENOPROTOOPT (10042) Bad protocol option A bad option or level was specified in a getsockopt(2) or setsockopt(2) call. A protocol was specified in the socket function call that does not support the semantics of the socket type requested. Berkeley description: An operation was attempted on something that is not a socket.
WinSock description: No equivalent. Winsock Error 10061 Of the two that can fail, neither of them set an error value you can retrieve from WSAGetLastError() (refer to Chapter 10, "Support Routines" for more information on any of these For example, a socket call requests a SOCK_DGRAM socket, but specifies a stream protocol. An invalid policy object was found in the QoS provider-specific buffer.
This article provides advice that tells you the best way to successfully treat your Microsoft Windows Winsock Error 10004, Error -107 error messages both by hand and / or automatically. WSAENOPROTOOPT 10042 Bad protocol option. Socket Error 10053 Developer suggestions: Assume bind() will fail with this error. Socket Error Codes Linux That's about one-quarter of the error values that aren't even used!
Berkeley description: A required address was omitted from an operation on a socket. WinSock functions: WSACancelAsyncRequest() Additional functions: Berkeley sockets connect() returns this error on subsequent calls, after an initial call on a non-blocking socket. The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. The Windows Sockets API does not have analogs for the Berkeley perror() and herror() functions that take the error value as input, and output the (short) text of each error value
We chose to go with the server code in this tutorial as there are more things to go wrong, as you would appreciate. Socket Error 10061 Connection Refused An address incompatible with the requested protocol was used. WinSock functions:
In this case, it might be possible to check the count of TCP RST packets received, or ICMP Port Unreachable packets.
For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency. You are unlikely to encounter them. Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below. Winsock Error 10054 Fix Berkeley description: A socket operation encountered a dead network.
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. WSAENETRESET 10052 Network dropped connection on reset. after the first failed with WSAEWOULDBLOCK). Developer suggestions: Things an application developer can do to avoid the error.
