An application used a Windows Sockets function which directly maps to a Windows function. However, there are some TCP/IP dialers that install their own Winsock.dll which may not be compatible with our programs. Source

This error occurs when the sin_port value is zero in a sockaddr_in structure for connect or sendto. The requested address is not valid WSAENETDOWN (10050) Network is down . An operation was attempted to an unreachable network. This Win32 error is also associated with overlapped I/O. weblink

Socket Error 10054

The WSAGetLastError function returns the last error that occurred for the calling thread. For information on how to handle error codes when porting socket applications to Winsock, see Error Codes - errno, h_errno and WSAGetLastError. No connection could be made because the target machine actively refused it. Typically, though, Winsock generates WSAENETUNREACH when it receives a 'host unreachable' ICMP message from a router instead of WSAEHOSTUNREACH.

  1. WSAEDQUOT 10069 Disk quota exceeded.
  2. A socket operation was attempted to an unreachable host WSAEPROCLIM (10067) Too many processes.
  3. If you used a hostname, did it resolve to the correct address?
  4. Client programs usually need not call bind at all - connect will choose an unused port automatically. 10049 Cannot assign requested address.

What Is A Socket Error This error most commonly occurs when attempting to use a broadcast address in sendto or WSASendTo, in which broadcast permission has not been set with setsockopt and the SO_BROADCAST option. 10014WSAEFAULT WinSock description: The 'address' they refer to, typically refers to the local 'socket name', which is made up of the 3-tuple: protocol, port-number and IP address. http://stackoverflow.com/questions/11532311/winsock-send-always-returns-error-10057-in-server For example, calling connect on a nonblocking socket will return this error because the connection request cannot be completed immediately. 10036WSAEINPROGRESS Operation now in progress.

It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed. Socket Error Codes Linux This error is returned by WSAStartup if the Windows Sockets implementation cannot function at this time because the underlying system it uses to provide network services is currently unavailable. 10093 Successful Any other type of operation might also return this error - for example, setsockopt setting SO_KEEPALIVE if the connection has been reset. 10058 Cannot send after socket shutdown. No such host is known WSATRY_AGAIN (11002) Nonauthoritative host not found.

You would need to update your Winsock to a supported version. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. When bind is called with a wildcard address (involving ADDR_ANY), a WSAEADDRINUSE error could be delayed until the specific address is committed. Socket Error 10061 Connection Refused For instance, if the length of an argument, which is a sockaddr structure, is smaller than the sizeof(sockaddr).

How can tilting a N64 cartridge causes such subtle glitches? WSAEUSERS 10068 User quota exceeded. Too many open sockets WSAEWOULDBLOCK (10035) Resource temporarily unavailable . Check This Out This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small.

This error also could occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as 'orphans'). This normally results if the peer application on the remote host is suddenly stopped, the host is rebooted, the host or remote network interface is disabled, or the remote host uses This code is interchangeable with WSA_E_CANCELLED. Note that this error is returned by the operating system, so the error number may change in future releases of Windows.

By calling shutdown, you do a partial close of a socket, which means you have discontinued sending.
