Wince Socket Error Codes
For server applications that need to bind multiple sockets to the same port number, consider using setsockopt (SO_REUSEADDR). Error code: %ld\n", WSAGetLastError()); else printf("Server: closesocket() is OK...\n"); // When your application is finished call WSACleanup. Berkeley description: Normally results from an attempt to create a socket with an address not on this machine. WinSock description: The Windows Sockets definition of this error is very different from Berkeley. http://3cq.org/socket-error/win32-socket-error-codes.php
No connection could be made because the target machine actively refused it. But the connection is broken is 50 seconds. –Thangamani Palanisamy Jun 27 at 10:19 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted That error Collapse | Copy Code int GetSocketState(); Returns one of the following states: CCESocket::NONE (=0) CCESocket::DISCONNECTED (=1) CCESocket::CREATED (=2)
Socket Error 10038
Microsoft C description: Bad file number. It also has a specific meaning for setsockopt(). The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. Then it works again for some time.
A QoS error occurred due to lack of resources. Note that this error occurs rarely since a WinSock implementation cannot reliably detect hardware problems. Reading data You already know one of the four ways to read data: direct read through the first OnReceive event. Socket Error 10049 Ran out of disk quota.
In this case, the 2nd application will fail with WSAEADDRINUSE. Socket Error Codes Linux The attempted operation is not supported for the type of object referenced. Is the router up and running (check by pinging it, and then ping an address on the other side of it)? after failed calls to inet_addr() or gethostbyname()), then simply test your address value for zero before you pass it to sendto().
Check that your network system (WinSock implementation) has a utility that shows network statistics. Socket Error 10053 It is a nonfatal error, and the operation should be retried later. For instance, if the length of an argument, which is a sockaddr structure, is smaller than the sizeof(sockaddr). What is a keep-alive activity and how can it break a connection?

Users should check: That the appropriate Windows Sockets DLL file is in the current path. https://msdn.microsoft.com/en-us/library/aa450301.aspx For protocol and services resolution, the name or number was not found in the respective database. Socket Error 10038 Only SOCK_STREAM is supported; the SOCK_DGRAM type is not supported by IrDA. Socket Error 10054 Connection Reset By Peer 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.

WSAEALREADY 10037 Operation already in progress. Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket) Windows Socket Error Windows 10
Running Both the UDP Receiver/Server and UDP Sender/Client Testing the UDP Client and select Server Programs in Private Network Message-Based Protocols Releasing Socket Resources Miscellaneous APIs getpeername() getsockname() WSADuplicateSocket() Windows CE User suggestions: Did you enter a destination hostname? The Header is Winsock2.h and the Library is Ws2.lib. < Connectionless-UDP, Client & Server | Winsock2 Main | Chap 2: Protocol Characteristics > my review here In some cases these errors are platform dependent.
Windows CE All the information in the preceding sections applies equally to Windows CE. Winsock Error 10054 Fix The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. Developer suggestions: Always check the return value from a memory allocation to be sure it succeeded.
name [in] Address to assign to the socket from the sockaddr structure.
Note: Although connect() and FD_CONNECT also have this error listed, the documentation specifically states that WSAEADDRNOTAVAIL is appropriate if INADDR_ANY is passed as a destination address. WSA_QOS_EFLOWSPEC 11017 QoS flowspec error. Packet read: you can read single packets, exactly as they were received. Socket Error 11004 The address manipulation functions, inet_ntoa() andinet_addr(), can fail.
This error is returned by the WSCGetProviderInfo and WSCGetProviderInfo32 functions if the protocol entry specified could not be found. If so, then the application might have had a problem resolving the name (see suggestions at WSATRY_AGAIN for more information). User suggestions: Don't try running two of the same types of server applications on the same machine. get redirected here Note that this error is returned by the operating system, so the error number may change in future releases of Windows.
Typically, though, WinSock generates this error when it receives a "host unreachable" ICMP message from a router. WinSock description: Same as Berkeley. "You can't make a silk purse from a sow's ear." Detailed descriptions: accept(), listen(): socket is not of type that supports connection-oriented service. getsockname(ReceivingSocket, (SOCKADDR *)&ReceiverAddr, (int *)sizeof(ReceiverAddr)); printf("Server: Receiving IP(s) used: %s\n", inet_ntoa(ReceiverAddr.sin_addr)); printf("Server: Receiving port used: %d\n", htons(ReceiverAddr.sin_port)); printf("Server: I\'m ready to receive a datagram...\n"); SelectTiming This has no network-relevant analog (although the "inode" reference could refer to a network file system entry).
recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is Berkeley description: This is a temporary condition and later calls to the same routine may complete normally (also known as EAGAIN error in Berkeley Software Distribution version 4.3) WinSock description: Same You can call it at any time, even if the socket is already connected. WinSock description: Same as Berkeley.
An existing connection was forcibly closed by the remote host. That's about one-quarter of the error values that aren't even used! WSA_QOS_EPSFILTERSPEC 11028 Invalid QoS provider-specific filterspec. 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(),
If you want your CE application to have a command-bar button, change the dialog box to have the WS_OVERLAPPED style instead of WS_POPUP. The Win32 function is indicating a lack of required memory resources. A connect request was made on an already-connected socket. Unblock the Windows firewall if any. 3.
Socket type definitions appear in Winsock2.h, which will be periodically updated as new socket types, address families, and protocols are defined. This documentation is archived and is not being maintained. ServerConnect() then calls bind() to tie the socket to that address, and listen() to wait for client connection requests. WSAEINVALIDPROVIDER 10105 Service provider is invalid.
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.
