The address manipulation functions, inet_ntoa() andinet_addr(), can fail. User suggestions: Check the obvious first: check that the destination address is a valid IP address. For example, if a call to WaitForMultipleEvents fails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs. Microsoft C description: Permission denied. have a peek here
WSAEMSGSIZE (10040) Message too long. The requested address is not valid in its context. WSAGetLastError() and WSAIsBlocking() cannot fail. WSA_QOS_EPSFLOWSPEC 11027 Invalid QoS provider-specific flowspec.
You should simply ignore this error when it occurs. Try a "traceroute" to the host you were connected to. Additionally, for the getXbyY class of functions, error codes are not made available through the h_errno variable. In this case, the WSAEBADF error might mean the same as a WSAENOTSOCK error.
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. Any application that uses a blocking socket or calls any blocking functions must handle this error. Applications that use WSAGetOverlappedResult (with the fWait flag set to FALSE) in a polling mode to determine when an overlapped operation has completed, get this error code until the operation is Winsock Error 10061 When the communication does not work, we get an error (apparently while a process was trying to send data).
In WinSock it means a blocking operation was interrupted by a call to WSACancelBlockingCall. Socket Error 10054 Connection Reset By Peer A connect request was made on an already-connected socket. Other information varies between different errors. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740673(v=vs.85).aspx WSA_QOS_BAD_OBJECT 11013 QoS bad object.
At the moment we do not understand if we have a software problem or a configuration issue: maybe we should check something in the windows registry? Windows Socket Error Windows 10 This is just a style recommendation. WSA_QOS_EPSFILTERSPEC 11028 Invalid QoS provider-specific filterspec. WinSock description: No equivalent.
WinSock description: No equivalent. If you're on a serial connection, your local router is the IP address of the host you initially logged onto with SLIP or PPP. Socket Error Codes Linux The specified class was not found. Socket Error 10053 WSAEISCONN (10056) Socket is already connected.
An invalid QoS provider-specific buffer. http://sysgsm.com/socket-error/windows-socket-version-2-api-error-code.html The Winsock2.h header file included with the Microsoft Windows Software Development Kit (SDK), Platform Software Development Kit (SDK), and Visual Studio still contains a commented out block of defines within an Developer suggestions: to make your application more portable: with datagram sockets don't use connect() and sendto() on the same datagram socket in an application, and always "disconnect" before calling connect() more try to ping the server(s)). Socket Error 11004
In earlier versions of the Platform Software Development Kit (SDK), HRESULT_FROM_WIN32 was defined as a macro in the Winerror.h header file. Developer suggestions: You need to be prepared to handle this error on any functions that reference blocking sockets, or any calls to blocking functions, if you allow the user to cancel Most of the text comes from the output from the "man errno" command on Unix. http://sysgsm.com/socket-error/windows-sockets-version-2-api-error-code-documentation.html recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is
This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server. Winsock Error Windows 7 Functionless Errors There are a total of fifty unique WinSock error values. An invalid or inconsistent flowspec was found in the QOS structure.
Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Additional functions: With a datagram socket: send() or sendto(), or FD_READ. Although some WinSock implementations might not issue other errors if a connection fails, so you can handle this error as you would others that indicate connection failure. Winsock Error 10054 Fix Note: this error may also result if you are trying to send a multicast packet and the default gateway does not support multicast (check your interface configuration).
WSA_QOS_EPROVSPECBUF 11018 Invalid QoS provider buffer. The missing functions are getprotobyname(), getprotobynumber(), getservbyname(), and getservbyport(). The system detected an invalid pointer address in attempting to use a pointer argument of a call. this contact form Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g.
With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). Check that your network system (WinSock implementation) has a utility that shows network statistics. Companion file .qgs~ What is the max time it would take yeast to "clean up"? WSAEINPROGRESS 10036 Operation now in progress.
Apparently, the Windows Sockets specification left this out by oversight. WSAEHOSTDOWN 10064 Host is down. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. Either the application has not called WSAStartup or WSAStartup failed.
WinSock description: Partly the same as Berkeley. Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e. 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.
WSA_QOS_GENERIC_ERROR 11015 QoS generic error. You are unlikely to encounter them. WinSock description: Same as Berkeley.
