Events
------
* `WEBSOCKET_EVENT_BEGIN': The client thread is running.
* `WEBSOCKET_EVENT_BEFORE_CONNECT`: The client is about to connect.
* `WEBSOCKET_EVENT_CONNECTED`: The client has successfully established a connection to the server. The client is now ready to send and receive data. Contains no event data.
* `WEBSOCKET_EVENT_DATA`: The client has successfully received and parsed a WebSocket frame. The event data contains a pointer to the payload data, the length of the payload data as well as the opcode of the received frame. A message may be fragmented into multiple events if the length exceeds the buffer size. This event will also be posted for non-payload frames, e.g. pong or connection close frames.
* `WEBSOCKET_EVENT_ERROR`: The client has experienced an error. Examples include transport write or read failures.
* `WEBSOCKET_EVENT_DISCONNECTED`: The client has aborted the connection due to the transport layer failing to read data, e.g. because the server is unavailable. Contains no event data.
* `WEBSOCKET_EVENT_CLOSED`: The connection has been closed cleanly.
* `WEBSOCKET_EVENT_FINISH': The client thread is about to exit.
If the client handle is needed in the event handler it can be accessed through the pointer passed to the event handler:
