Do glass window in space station/space shuttle/other space craft have practical usage? The server application might need to call htons() to translate the port to network byte order in the sockaddr structure. Source

For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency. Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below. Any application that uses a blocking socket or calls any blocking functions must handle this error.

It's also possible that the local services file has an incorrect port number (although it's unlikely). Socket Error 10054 Connection Reset By Peer 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.

User suggestions: Do you have the WinSock DLL that supports the version of the WinSock specification required by the application? Socket Error Codes Linux Two functions that are conspicuously absent from the current function list above are shutdown() and close socket().

Running the application with this change will give you error 10043 (WSAEPROTONOSUPPORT) which means 'protocol not supported'. http://nbxcorp.com/socket-error/winsock2-error-codes.html As you see WSAGetLastError() is an essential function to use, if you want to know why your application might be failing. The WSAGetLastError function is one of the only functions in the Winsock 2.2 DLL that can be called in the case of a WSAStartup failure.   The Windows Sockets extended error This error occurs if the sin_addr is INADDR_ANY (i.e. Socket Error 10049

WSAETIMEDOUT 10060 Connection timed out. If a source file includes code which inspects errno for both socket and non-socket functions, this mechanism cannot be used.

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. Wsagetlasterror 10054 You cannot mix and match (WINSOCK DLLs must be supplied by the same vendor that provided your underlying protocol stack). So, if we run the application it will report the following error in our console.

Syntax C++ Copy int WSAGetLastError(void); Parameters This function has no parameters.

WSAEAFNOSUPPORT 10047 Address family not supported by protocol family. 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. For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr). Wsagetlasterror 0 WinSock functions: Additional functions: For Berkeley compatibility, the socket() function should fail with this error if an unsupported address family is requested.

This documentation is archived and is not being maintained. WSAEPFNOSUPPORT 10046 Protocol family not supported.

Maximum server memory my matrix doesnt fit the page Proof of turings halting problem We don't support this API version. A list of winsock error codes can be found here and also at the bottom of this tutorial for your convenience. These defines remain commented out in the Winsock2.h header within an #ifdef 0 and #endif block. WinSock functions: accept(), bind(), closesocket(), connect(), gethostbyaddr(), gethostbyname(), gethostname(), getpeername(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), getsockname(), getsockopt(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(),

For example, you shouldn't necessarily expect to be able to use NS addresses with ARPA Internet protocols. However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error. Developer suggestions: Things an application developer can do to avoid the error. The WSAGetLastError function should not be used to check for an extended error value on receipt of an asynchronous message.

WSAEDQUOT 10069 Disc quota exceeded. Berkeley description: A component of a path name exceeded 255 (MAXNAMELEN) characters, or an entire path name exceeded 1023 (MAXPATHLEN-1) characters.
