Socket Error 10053 If you are using a name server(s), check whether the server host(s) are up (e.g.

Running the application with this change will give you error 10043 (WSAEPROTONOSUPPORT) which means 'protocol not supported'. 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. Prerequisites Project type: Console Include files: winsock2.h Library files: ws2_32.lib Error Handling You would remember in our previous tutorials that first we must initialize Winsock.

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.
