Enumeration Type Documentation

value

enum websocketpp::error::value

Enumerator
general	Catch-all library error.
send_queue_full	send attempted when endpoint write queue was full
payload_violation	Attempted an operation using a payload that was improperly formatted ex: invalid UTF8 encoding on a text message.
endpoint_not_secure	Attempted to open a secure connection with an insecure endpoint.
endpoint_unavailable	Attempted an operation that required an endpoint that is no longer available. This is usually because the endpoint went out of scope before a connection that it created.
invalid_uri	An invalid uri was supplied.
no_outgoing_buffers	The endpoint is out of outgoing message buffers.
no_incoming_buffers	The endpoint is out of incoming message buffers.
invalid_state	The connection was in the wrong state for this operation.
bad_close_code	Unable to parse close code.
reserved_close_code	Close code is in a reserved range.
invalid_close_code	Close code is invalid.
invalid_utf8	Invalid UTF-8.
invalid_subprotocol	Invalid subprotocol.
bad_connection	An operation was attempted on a connection that did not exist or was already deleted.
test	Unit testing utility error code.
con_creation_failed	Connection creation attempted failed.
unrequested_subprotocol	Selected subprotocol was not requested by the client.
client_only	Attempted to use a client specific feature on a server endpoint.
server_only	Attempted to use a server specific feature on a client endpoint.
http_connection_ended	HTTP connection ended.
open_handshake_timeout	WebSocket opening handshake timed out.
close_handshake_timeout	WebSocket close handshake timed out.
invalid_port	Invalid port in URI.
async_accept_not_listening	An async accept operation failed because the underlying transport has been requested to not listen for new connections anymore.
operation_canceled	The requested operation was canceled.
rejected	Connection rejected.
upgrade_required	Upgrade Required. This happens if an HTTP request is made to a WebSocket++ server that doesn't implement an http handler
invalid_version	Invalid WebSocket protocol version.
unsupported_version	Unsupported WebSocket protocol version.
http_parse_error	HTTP parse error.
extension_neg_failed	Extension negotiation failed.
