| Enumerator |
|---|
| None | The Socket operation succeeded.
|
| Any | An unspecified Socket error has occurred.
|
| Success | The Socket operation succeeded.
|
| Unspecified | An unspecified Socket error has occurred.
|
| Interrupted | A blocking operation was interrupted.
|
| InvalidArgument | An invalid argument was supplied.
|
| TooManyOpenSockets | Too many open sockets.
|
| WouldBlock | A non-blocking socket operation could not be completed immediately.
|
| InProgress | A blocking operation is currently executing.
|
| AlreadyInProgress | An operation was attempted on a non-blocking socket that already had an operation in progress.
|
| NotSocket | An operation was attempted on something that is not a socket.
|
| DestinationAddressRequired | A required address was omitted from an operation on a socket.
|
| MessageSize | A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself.
|
| ProtoType | A protocol was specified in the socket function call that does not support the semantics of the socket type requested.
|
| ProtocolOption | An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call.
|
| ProtocolNotSupported | The requested protocol has not been configured into the system, or no implementation for it exists.
|
| SocketNotSupported | The support for the specified socket type does not exist in this address family.
|
| OperationNotSupported | The attempted operation is not supported for the type of object referenced.
|
| ProtocolFamilyNotSupported | The protocol family has not been configured into the system or no implementation for it exists.
|
| AddressFamilyNotSupported | An address incompatible with the requested protocol was used.
|
| AddressAlreadyInUse | Only one usage of each socket address (protocol/network address/port) is normally permitted.
|
| AddressNotAvailable | The requested address is not valid in its context.
|
| NetworkDown | A socket operation encountered a dead network.
|
| NetworkUnreachable | A socket operation was attempted to an unreachable network.
|
| NetworkReset | The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress.
|
| ConnectionAborted | An established connection was aborted by the software in your host machine.
|
| ConnectionReset | An existing connection was forcibly closed by the remote host.
|
| NoBufferSpaceAvailable | An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.
|
| IsConnected | A connect request was made on an already connected socket.
|
| NotConnected | A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
|
| Shutdown | A request to send or receive data was disallowed because the socket had already been shut down in that direction with a previous shutdown call.
|
| TimedOut | A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
|
| ConnectionRefused | No connection could be made because the target machine actively refused it.
|
| HostDown | A socket operation failed because the destination host was down.
|
| HostUnreachable | A socket operation was attempted to an unreachable host.
|
| ProcessLimit | A Sockets implementation may have a limit on the number of applications that may use it simultaneously.
|
| SystemNotReady | Startup cannot function at this time because the underlying system it uses to provide network services is currently unavailable.
|
| VersionNotSupported | The Sockets version requested is not supported.
|
| NotInitialized | Either the application has not called Startup, or Startup failed.
|
| Disconnecting | Returned by Recv or RecvFrom to indicate the remote party has initiated a graceful shutdown sequence.
|
| HostNotFound | No such host is known.
|
| TryAgain | This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server.
