A NULL value for lpGQOS indicates no application-supplied group quality of service. 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 SO_DEBUG, SO_DONTROUTE, SO_RCVBUF, SO_SNDBUF, TCP_NODELAY: optional socket options. You can avoid making the mistake of trying to send on a socket after you've initiated a close, by keeping track of the socket state in your application (and checking it

It could also be a timing issue. For connectionless sockets, name can indicate any valid address, including a broadcast address. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). This will verify that the destination network is functioning.

Are you using an optional level or socket option that may not be supported on all WinSock implementations? How To Fix Socket Error Syntax C++ Copy int WSAGetLastError(void); Parameters This function has no parameters.

If so, treat this as a non-fatal error and ignore it, if possible.

The address manipulation functions, inet_ntoa() andinet_addr(), can fail. WSAENETUNREACH 10051 Network is unreachable. Socket Error 10053 Note that this error is returned by the operating system, so the error number may change in future releases of Windows. Socket Error 10049 An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.

Is there a directory equivalent of /dev/null in Linux? Some of these functions cannot fail, which explains their absence from the error list below.

These error codes and a short text description associated with an error code are defined in the Winerror.h header file. Socket Error 10054 Connection Reset By Peer

If so, then the application might have had a problem resolving the name (see suggestions at WSATRY_AGAIN for more information). See other suggestions under WSAECONNABORTED. A completion indication will be given later when the operation has been completed. WinSock description: Same as Berkeley.

It may also indicate you are not closing the applications properly. Socket Error 10061 Usually displayed by Glink as 'Server not responding'. 2AFB (WSANO_RECOVERY) Non-recoverable errors, FORMERR, REFUSED, NOTIMP.

User suggestions: There are a number of things to check, that might help to identify why the failure occurred.
