WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), See also: WSAHOST_NOT_FOUND, WSANO_DATA, WSATRY_AGAIN WSASYSNOTREADY (10091) Network subsystem is unavailable Berkeley description: No equivalent. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). WSAEPROTOTYPE 10041 Protocol wrong type for socket. How should I calculate the determinant? http://jamisonsoftware.com/socket-error/get-socket-error-aborting-code-10054.php
Berkeley description: A socket operation failed because the destination host was down. Detailed descriptions: the specific meanings that some WinSock functions have for some errors. It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed. Do a traceroute to the destination to verify all routers along the connection path are operational. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx
An invalid value was given for one of the arguments to a function. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. For example, this error is returned if sendto is called with the remote address of ADDR_ANY. WSA_QOS_POLICY_FAILURE 11011 QoS policy failure.
For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr). If no error had occurred, or the error had been cleared with socket_clear_error(), the function returns 0. Usually this occurs when a socket descriptor to a socket that cannot support this operation is trying to accept a connection on a datagram socket. Socket Error 10053 There are only a few possible causes for this error: you tried to connect to the wrong port.
If the socket resource is omitted, the error code of the last failed socket function is returned. The WinSock implementation will not allow you to send after this. WSAEISCONN (10056) Socket is already connected. https://gist.github.com/gabrielfalcao/4216897 An application used a Windows Sockets function which directly maps to a Windows function.
This can help you (or your support staff) to zero-in on what's wrong when your application runs into a problem. Socket Error 10049 Note the British spelling (with an 'S' instead of a 'Z'). The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. Developer suggestions: If you have a network analyzer available, you can quickly check if the destination port number and host address are what you expect.
A function fails with WSAEAFNOSUPPORT if the address family referenced in sockaddr is not compatible with the referenced socket's protocol. WinSock description: Same as Berkeley for host resolution. Socket Error Codes Linux No connection could be made because the target computer actively refused it. What Is A Socket Error Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you!
Return code/valueDescription WSA_INVALID_HANDLE 6 Specified event object handle is invalid. Get More Info WSA_OPERATION_ABORTED 995 Overlapped operation aborted. The specified class was not found. For example, the error can occur when an attempt is made to read from a file that is not open, to open an existing read-only file for writing, or to open Socket Error 10054 Connection Reset By Peer
In some instances, it also refers to the current state of the socket input parameter. To save myself, and a few others, some time in the future... /usr/include/asm-generic/errno-base.h #ifndef _ASM_GENERIC_ERRNO_BASE_H #define _ASM_GENERIC_ERRNO_BASE_H #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such So, for example, you can expect this error if a WinSock implementation doesn't support socket type SOCK_RAW within the Internet address family (AF_INET). useful reference For inet_addr(), this could mean the content of the buffer passed or the buffer itself is invalid.
For more information on debugging problems, see Chapter 13, "Debugging." Errorless Functions Eight of the forty-six functions in the Windows Sockets API are not referenced in any of the "WinSock function" Socket Error 11004 WSAEMFILE 10024 Too many open files. Almost all of the sockets functions may fail under certain conditions and therefore emit an E_WARNING message describing the error.
However, it also occurs when an application passes an invalid pointer value. Developer suggestion: are you trying to use an optional feature? A database query failed because it was actively refused. Windows Socket Error Windows 10 Return Values This function returns a socket error code.
But most of these function-less errors are simply out of place; they are inappropriate to the Windows Sockets API as it exists in the v1.1 specification. The only time a WinSock might use this error--at least with a TCP/IP implementation of WinSock--it fails a function with other errors (for example, WSAETIMEDOUT). WSA_QOS_EOBJLENGTH 11022 Invalid QoS object length. http://jamisonsoftware.com/socket-error/genesis-windows-socket-error-code-10061.php This is what occurs in Berkeley Sockets.
Ping the remote host you were connected to. Note that this error is returned by the operating system, so the error number may change in future releases of Windows. User suggestions: Do you have the WinSock DLL that supports the version of the WinSock specification required by the application? WSAECANCELLED 10103 Call has been canceled.
If you have entered an IP Address, try entering a server and domain name instead (e.g. The remote server may be temporarily or permanently inaccessible (try again later). Putting the socket call and the test for < 0 in one statement, the above code could look like this, and you'll be a real UNIX pro: #include
