Win32 Socket Error Codes


If you have more than one server configured, the hostname query fails only after the Winsock DLL has queried all servers. For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM. For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM. 10042 - WSAENOPROTOOPT - Bad protocol option. This could happen with a call to another function later, including connect, listen, WSAConnect, or WSAJoinLeaf. have a peek at this web-site

The Windows Sockets API provides access to "low-level" API's (like the transport protocols TCP and UDP), so this error is not relevant to WinSock. Not implemented: name server does not perform specified operation. A socket already has a type (a protocol), and each sockaddr structure has an address family field to define its format. If you can add those diagnostics and then set up a stress test that focuses on open and close areas in your program (you may need to strip down the code https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Socket Error Codes Linux

WSAEHOSTDOWN 10064 Host is down. WinSock description: No equivalent. If users are not receiving notices about undeliverable messages then you do not need to take any action.

This error signifies that an attempt was made to access a file (or, in some cases, a directory) in a way that is incompatible with the file's attributes. WinSock functions: recv(), recvfrom(), send(), sendto(), with datastream sockets only. If the signal handler performs a normal return, the interrupted function call will seem to have returned the error condition. Socket Error 11004 WSA_QOS_ESHAPERATEOBJ 11030 Invalid QoS shaping rate object.

Any of the WinSock name resolution functions can fail with this error. Socket Error 10054 Connection Reset By Peer The error can also occur in an attempt to rename a file or directory or to remove an existing directory. all other functions: retry the operation again later since it cannot be satisfied at this time. Berkeley description: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket) no address was supplied.

Recv and Recvfrom: If the datagram you read is larger than the buffer you supplied, then Winsock truncates the datagram (i.e. Winsock Error 10061 If so, is there an older DLL in a directory in the path ahead of the directory containing the newer DLL? Note that this error is returned by the operating system, so the error number may change in future releases of Windows. Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below.

Socket Error 10054 Connection Reset By Peer

WSAEADDRNOTAVAIL 10049 Cannot assign requested address. No more file handles are available, so no more files can be opened.. Socket Error Codes Linux This is not a software error, another type of name server request may be successful. Socket Error 10053 we don't recommend it).

Berkeley description: The attempted operation is not supported for the type of object referenced. Check This Out Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than See also: WSAENETUNREACH WSAEINPROGRESS (10036) Operation now in progress. Socket Error 10049

A list of winsock error codes can be found here and also at the bottom of this tutorial for your convenience. As we pointed out earlier, your application should be ready to encounter any error at any time. 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 Source WSAEPFNOSUPPORT 10046 Protocol family not supported.

Although the specification doesn't list an error for a function, it does allow for it. Winsock Error Windows 7 Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP. The WinSock description for this error is "the specified socket type is not supported in this address family," which qualifies the error condition a bit more than the Berkeley explanation does.

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

Some of these functions cannot fail, which explains their absence from the error list below. WinSock functions: connect(), sendto(), FD_CONNECT WSAEDQUOT (10069) Disc quota exceeded. Berkeley description: No equivalent in 4.3 BSD or compatible operating systems. Winsock Error 10054 Fix This error is returned if any Windows Sockets API function is called while a blocking function is in progress.

WSAECONNRESET (10054) Connection reset by peer A connection was forcibly closed by a peer. The address manipulation functions, inet_ntoa() andinet_addr(), can fail. WSAVERNOTSUPPORTED (10092) WINSOCK DLL Version out of range The current Winsock implementation does not support the Windows Sockets specification version requested by the application. have a peek here WSAESHUTDOWN 10058 Cannot send after socket shutdown.

Berkeley description: A connection abort was caused internal to your host machine. That's about one-quarter of the error values that aren't even used! For instance, if the length of an argument, which is a sockaddr structure, is smaller than the sizeof(sockaddr).
