GioDBusConnectionflush

since: 2.26

Declaration [src]

void
g_dbus_connection_flush (
  GDBusConnection* connection,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Asynchronously flushes connection, that is, writes all queued outgoing message to the transport and then flushes the transport (using g_output_stream_flush_async()). This is useful in programs that wants to emit a D-Bus signal and then exit immediately. Without flushing the connection, there is no guaranteed that the message has been sent to the networking buffers in the OS kernel.

This is an asynchronous method. When the operation is finished, callback will be invoked in the [thread-default main context][g-main-context-push-thread-default] of the thread you are calling this method from. You can then call g_dbus_connection_flush_finish() to get the result of the operation. See g_dbus_connection_flush_sync() for the synchronous version.
