"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. you're trying to share a socket between tasks). news
User suggestions: see WSAENETUNREACH for details WinSock functions:
Basically, you want to identify where the problem occurred. 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 send() or sendto(): out of buffer space, so try again later or wait until FD_WRITE notification (WSAAsyncSelect()) or select() writefds is set. Although the specification doesn't list an error for a function, it does allow for it.
Unfortunately, to find out what these errors mean you need to contact that WinSock provider. User suggestions: Check the obvious first: check that the destination address is a valid IP address. If not, check with your WinSock vendor to see if they have a newer WinSock available. Windows Socket Error Windows 10 The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete.
Ignore it. Whether to handle it as a fatal error or non-fatal error depends on the application and the context, so it's entirely up to you to decide. WinSock functions: getsockopt(), setsockopt() Additional functions: Bad IP headers can cause routers and remote hosts to issue ICMP "parameter problem" messages, which result in a ENOPROTOOPT error on Berkeley-derived systems. http://stackoverflow.com/questions/14366048/bind-fails-with-windows-socket-error-10049 Berkeley description: A socket operation was attempted to an unreachable network.

Socket Error 10038 This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous.

More about the author WinSock description: Partly the same as Berkeley.
You will usually see this error when a server refuses a connection from a client, because the server is not listening on that port. 10064 WSAEHOSTDOWN -- Host is down. 10065 Winsock Error 10054 Fix WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available"). As we pointed out earlier, your application should be ready to encounter any error at any time.
closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. The Windows Sockets API does not have analogs for the Berkeley perror() and herror() functions that take the error value as input, and output the (short) text of each error value Additional functions: Any functions that takes a pointer as an input parameter: inet_addr(), inet_ntoa(), ioctlsocket(), gethostbyaddr(), gethostbyname(), getservbyname(), getservbyport(), WSAAsyncGetHostByName(), WSAAsyncGetHostByAddr(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber, WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSASetBlockingHook() WSAEHOSTDOWN (10064) Host is down. Wsagetlasterror 0 If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.
WinSock functions: send(), sendto() Additional functions: setsockopt() and any function that takes a socket (or file handle) as an input parameter. It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine.

Check that your network system (WinSock implementation) has a utility that shows network statistics.

User suggestions: Chances are the network subsystem is misconfigured or inactive. WinSock description: Same as Berkeley for host resolution.
Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. Usually this occurs when a file descriptor refers to a file or socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. WSAEOPNOTSUPP (10045) Operation not supported. Berkeley description: A file descriptor argument was out of range, referred to no open file, or a read (write) request was made to a file that was only open for writing
Player claims their wizard character knows everything (from books). It would also timeout if a (FIN)ish TCP packet is not ACK'd (and even if the FIN is ACK'd, it will eventually timeout if a FIN is not returned). Instead, let the network system assign the local port (very few application protocols require a client to bind to a specific port number or port number range). WinSock functions: socket() See also: WSAEPROTOTYPE, WSAEPROTONOSUPPORT WSAESTALE (10070) Stale NFS file handle.

The v1.1 specification also lists connect(), although it does not allocate a descriptor. WinSock description: Partly the same as Berkeley.
