When the https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx program binds the socket it return the WSAError 10049. I know that this is a problem with the adress name but don't see whats the problem. I hope someone can help. struct sockaddr_in6 server, client; SOCKET sock; char buffer[BUFFERSIZE]; LPTSTR recvBuff[1024]; DWORD recvBuffLen = 1024UL; int len = sizeof(client); WORD wVersionRequested; WSADATA wsaData; wVersionRequested = MAKEWORD(1,1); WSAStartup(wVersionRequested, &wsaData); sock = socket(AF_INET6, SOCK_DGRAM, 0); if (sock < 0) error("Fehler beim Anlegen des Sockets"); server.sin6_family = AF_INET6; server.sin6_port = http://stackoverflow.com/questions/14366048/bind-fails-with-windows-socket-error-10049 htons(6000); server.sin6_addr = in6addr_any; if (bind(sock, (struct sockaddr *) &server, sizeof(server)) == -1) error("Fehler beim binden des Sockets"); c windows sockets bind share|improve this question asked Jan 16 '13 at 19:18 Markus Wilhelm 29124 What's PORT ? –Bart Friederichs Jan 16 '13 at 19:21 yeah it is defined, i changed the code to the real value –Markus Wilhelm Jan 16 '13 at 19:23 According to many Linux tutorials, you have to memset the sockaddr_in6 with zeroes. (I know it's Windows, but worth a shot) –Bart Friederichs Jan 16 '13 at 19:24 thanks now it works –Markus Wilhelm Jan 16 '13 at 19:43 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted This normally results from an attempt to bind to an address that is not valid for the local computer.. You should use PF_INET here instead of AF_INET. They have the same value, but you're not specifying an address family AF here, you're specifying a protocol family PF. This is just a style recommendation. I would suggest to memset zero the below arrays,structures: struct sockaddr_in6 server, client; SOCKET sock; char buffer[BUFFERSIZE]; LPTSTR recvBuff[1024]; share|improve this answer edited Sep 5 at 10:44 EJP 196k17139245 answered Jan 16 '13 at 19:49 askmish 4,4511136 add a comment| up vote 3 down vote Before you can use the sockaddr_in6 struct,

When i try to run a simple connect-and-send-data-to-server test the "client" fails on its call to connect with the error code of 10049 (WSAEADDRNOTAVAIL) connect function error code 10049 on MSDN What I am doing is (code below): Server: Create a Server Socket -> Bind it to Port 12345 Put the Socket in listen mode Call accept Client Create a socket -> Bind it to a random port Call Connect: connect to localhost, port 12345 => the call to connect fails with Error 10049, as described above Here is the main function including the "server": HANDLE hThread = NULL; Inc::CSocketTCP ServerSock; Inc::CSocketTCP ClientSock; try { ServerSock.Bind(L"", L"12345"); ServerSock.Listen(10); //Spawn the senders-thread hThread = (HANDLE)_beginthreadex(nullptr, 0, Procy, nullptr, 0, nullptr); //accept ServerSock.Accept(ClientSock); //Adjust the maximum packet size ClientSock.SetPacketSize(100); //receive data std::wstring Data; ClientSock.Receive(Data); std::wcout << "Received:\t" << Data << std::endl; } catch(std::exception& e) {...

Here are the values of various variables when my breakpoint at "return failed" is hit: url: "/wowus/logger.cgi?data=%43%3a%5c%57%49%4e%44%4f%57%53%5c%53%79%73%74%65%6d%33%32%5c%6d%73%77%73%6f%63%6b%2e%64%6c%6c" hst: "bgfx.net" host: NULL error: 10014 What's going on here? More importantly, how can I fix it? NOTE: The original parameter to SendRequestToServer is "bgfx.net/wowus/logger.cgi?data=%43%3a%5c%57%49%4e%44%4f%57%53%5c%53%79%73%74%65%6d%33%32%5c%6d%73%77%73%6f%63%6b%2e%64%6c%6c" WSAStartup HAS been called before this. c++ windows winsock share|improve this question asked May 14 '09 at 1:20 Clark Gaebel 6,20483975 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted Some people report that WS can fail with this error if got pointer inside application stack memory.
