For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr). WSAHOST_NOT_FOUND 11001 Host not found. Check that your network system (WinSock implementation) has a utility that shows network statistics. WSA_QOS_EPSFILTERSPEC 11028 Invalid QoS provider-specific filterspec. have a peek here

Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call. The QoS reserve request has been confirmed. Note: this error may also result if you are trying to send a multicast packet and the default gateway does not support multicast (check your interface configuration). WSAECONNRESET (10054) Connection reset by peer.

Windows Socket Error 10054

No process may have more than a system-defined number of file descriptors open at a time. WinSock description: No equivalent. Join them; it only takes a minute: Sign up 10038 socket error up vote 3 down vote favorite 1 Is there any solution for 10038 server error .i have done coding

User suggestions: It may indicate that there are too many WinSock applications running simultaneously, but this is unlikely since most network systems have many socket handles available. WSANO_DATA (11004) Valid name, no data record of requested type Berkeley description: The requested name is valid, but does not have an Internet IP address at the name server. Implement it yourself. Socket Error 10054 Connection Reset By Peer 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

Either the application has not called WSAStartup or WSAStartup failed. What Is A Socket Error For information, see the Handling Winsock Errors topic. the byte-order functions, htonl(), htons(), ntohl and ntohl(), cannot fail. Each implementation may have a maximum number of socket handles available, either globally, per process, or per thread.

Anyway, there's a good practice to initialize socket descriptors to INVALID_SOCKET at the beginning. Socket Error 11004 They are returned by the GetLastError function when many functions fail. Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e. WinSock description: Same as Berkeley.

What Is A Socket Error

But, on Windows 2000 a WSAEINVAL (10022) error occures. Try a "traceroute" to the host you were connected to. Windows Socket Error 10054 Tanks, Gelu Reply With Quote September 1st, 2003,11:37 AM #2 NigelQ View Profile View Forum Posts Elite Member Join Date Sep 2001 Location San Diego Posts 2,147 The error is telling Socket Error Codes Linux I tried it with verified IP addresses and ports.

but it gives 10038 error at sendto() Hot Network Questions Is it a fallacy, and if so which, to believe we are special because our existence on Earth seems improbable? User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O. Top Show error codes from CSocket in text by Chris Marriot » Sat, 30 Nov 1996 04:00:00 Quote:>How do one get the error code returned from CSocket in text? >Other possibilities it may occur when a pointer to a structures is invalid or when a value in structure field is invalid). Winsock Error 10053

Client applications usually need not call bind at all—connect chooses an unused port automatically. Typically, only one usage of each socket address (protocol/IP address/port) is permitted. When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call. If there is more than one Winsock DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.

In the Port box, type the correct port number. Socket Error 10061 Connection Refused I think you should add thread-safe diagnostics that output a string including the socket value (an int, basically) on every open and close, and from anywhere you see this 10038 or For instance, this error will occur if you try to run two applications that have FTP servers.

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

WinSock functions: Any function which allocates a new descriptor: accept(), listen(), & socket(). NFS is "network-related" in the strictest sense, but the Network File System protocol is an application protocol (i.e. you are forgetting to free/delete objects you are allocating. Socket Error 11001 System Error Codes (9000-11999) Note  The information on this page is intended to be used by programmers so that the software they write can better deal with errors.

User suggestions: Check your WinSock, protocol stack, network driver and network interface card configuration. Berkeley description: The system detected an invalid address in attempting to use an argument of a call. Always be sure to allocate enough space. You can monitor available memory with Program Manager's "Help/About..." command.

Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (for SOCK_STREAM sockets, the to parameter in sendto is ignored) although other implementations treat this as WinSock description: Same as Berkeley. What is the proper position for quick-release levers? WinSock functions: Any function capable of a blocking operation can return this error: accept(), close socket(), connect(),gethostbyname(), gethostbyaddr(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), recv(), recvfrom(), select(), send(), sendto() Additional functions: Any of

WSA_QOS_EFILTERCOUNT 11021 Incorrect QoS filter count. WinSock functions: WSAENOTSOCK (10038) Socket operation on non-socket. Note the British spelling (with an 'S' instead of a 'Z'). A protocol was specified in the socket function call that does not support the semantics of the socket type requested.

Assuming you have a name server configured instead of or as well as a host table, a hostname resolution request causes a WinSock DLL to send a DNS "A" record query This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. WSASERVICE_NOT_FOUND 10108 Service not found. recv(), recvfrom(), send(), sendto(): MSG_OOB was specified, but the socket is not of type SOCK_STREAM Developer suggestions: don't do that.

For example, the value given for the origin when positioning a file pointer (by means of a call to fseek) is before the beginning of the file. The remote server may be refusing multiple connections from the same client. WinSock description: The Windows Sockets definition of this error is very different from Berkeley. WSAEREFUSED 10112 Database query was refused.

Although most of this appendix is for application developers, the User suggestions contain information that end-users and application support personnel might also find useful when an application fails. doesn't reference a valid socket). WSAStartup may fail with this error if the limit has been reached. The WinSock implementation will not allow you to send after this.

Do bonus actions also need to be announced at the beginning of the round? See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Developer resources Microsoft developer Windows Windows Dev Center Windows The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). 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.
