An invalid QoS flow descriptor was found in the flow descriptor list. WSAENOMORE 10102 No more results. No more results can be returned by the WSALookupServiceNext function. For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency. have a peek at these guys
WinSock functions: recv(), recvfrom(), send(), sendto(), FD_CLOSE Additional functions: Any function that does I/O on the network could generate this error. 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. So in Winsock applications the WSAEWOULDBLOCK error code would be returned, while in UNIX applications the EWOULDBLOCK error code would be returned. Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below.
User suggestions: Check the obvious first: check that the destination address is a valid IP address. Try changing the following line containing the WSAStartup() to this; int nResult=WSAStartup(MAKEWORD(0,0),&WsaDat); We have accidentaly instructed winsock to operate using version 0.0 within the wsock32.dll at runtime. For this tutorial we will be working with the final code used back in tutorial 2 (the blocking server). If not, check with your WinSock vendor to see if they have a newer WinSock available.
User suggestions: Some network systems have commands to report statistics. WSA_QOS_ADMISSION_FAILURE 11010 QoS admission error. Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address. Socket Error 10049 User suggestions: Don't try running two of the same types of server applications on the same machine.
If it is not valid we can use WSAGetLastError() to find what has gone amiss. This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto(). The v1.1 WinSock specification doesn't list any errors for these functions. Developer suggestions: Since there're only one corresponding protocol for each of the datagram and datastream socket types in the Internet address family, you should simply leave the value in the protocol
If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet Socket Error 11004 WinSock description: Same as Berkeley. This normally results from an attempt to bind to an address that is not valid for the local computer. See also: WSAENETUNREACH WSAEINPROGRESS (10036) Operation now in progress.
Now we examine error handling in greater detail. WSA_QOS_TRAFFIC_CTRL_ERROR 11014 QoS traffic control error. Socket Error 10054 An application used a Windows Sockets function that directly maps to a Windows function. Socket Error Codes Linux WSA Initialization failed: 10092 Press any key to continue . . .
As you can see from the comprehensive list of WinSock functions, this error is the catch-all. http://devstude.net/socket-error/wsa-error-code-10093.php How would you know what went wrong? Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function. Additional functions have been added over time to enhance Winsock for use by developers. 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. You need to call htons() to translate a constant value to network byte order before assigning it to the sin_port field in the sockaddr structure. Note that this error is returned by the operating system, so the error number may change in future releases of Windows. http://devstude.net/socket-error/wsa-error-code-183.php The call has been canceled.
Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified? Wsagetlasterror 10054 WinSock functions:
WSAGetLastError() and WSAIsBlocking() cannot fail.
Here is a useable macro: #define MAKEWORD(low, high) ((WORD)(((BYTE)(low)) | (((WORD)((BYTE)(high))) << 8))) WinSock functions: WSAStartup(). [Go to Top] Errors in Numerical Order WSABASEERR (0) No Error WSAEINTR (10004) Interrupted system An established connection was aborted by the software in your host computer, possibly due to a data transmission time-out or protocol error. Check that no old Windows Sockets DLL files are being accessed. Winsock Error 10061 A general QoS error.
The "address" they refer to, typically refers to the local "socket name", which is made up of the 3-tuple: protocol, port-number and IP address. Do a traceroute to try to determine where the failure occurs along the route between your host and the destination host. The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). http://devstude.net/socket-error/wsa-error-code.php This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous.
The item is not available locally. Not the answer you're looking for? WSAEAFNOSUPPORT 10047 Address family not supported by protocol family. This is usually caused by one or more of the function pointers being NULL.
The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. 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 The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete.
Note An application can call the WSAGetLastError function to determine the extended error code for other Windows sockets functions as is normally done in Windows Sockets even if the WSAStartup function fails Detailed descriptions: connect(): the operation is underway, but as yet incomplete. Berkeley description: Normally results from an attempt to create a socket with an address not on this machine. 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.
In this case, the 2nd application will fail with WSAEADDRINUSE. I discovered this while debugging a TransmitPackets problem that seemed quite random. Berkeley description: A socket operation failed because the destination host was down. It may also make explicit mention of other functions that can fail with this error.
