Method

SoupSessionwebsocket_connect_async

Declaration [src] 

void
soup_session_websocket_connect_async (
  SoupSession* session,
  SoupMessage* msg,
  const char* origin,
  char** protocols,
  int io_priority,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Asynchronously creates a SoupWebsocketConnection to communicate with a remote server.

All necessary WebSocket-related headers will be added to msg, and it will then be sent and asynchronously processed normally (including handling of redirection and HTTP authentication).

If the server returns “101 Switching Protocols”, then msg‘s status code and response headers will be updated, and then the WebSocket handshake will be completed. On success, soup_session_websocket_connect_finish() will return a new SoupWebsocketConnection. On failure it will return a GError.

If the server returns a status other than “101 Switching Protocols”, then msg will contain the complete response headers and body from the server’s response, and soup_session_websocket_connect_finish() will return SOUP_WEBSOCKET_ERROR_NOT_WEBSOCKET.

This method completes asynchronously. Use soup_session_websocket_connect_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
