* @short_description: GOutputStream for queuing data to output
* @title: GOutputStream class
* A #PurpleQueuedOutputStream is a #GOutputStream which allows data to be
* queued for outputting. It differs from a #GBufferedOutputStream in that
* it allows for data to be queued while other operations are in progress.
* The standard _get_type macro for #PurpleQueuedOutputStream.
#define PURPLE_TYPE_QUEUED_OUTPUT_STREAM purple_queued_output_stream_get_type()
* @base_stream: Base output stream to wrap with the queued stream
* Creates a new queued output stream for a base stream.
* @stream: #PurpleQueuedOutputStream to push bytes to
* @priority: IO priority of the request
* @cancellable: (allow-none): Optional #GCancellable object, NULL to ignore
* @callback: (scope async): Callback to call when the request is finished
* @user_data: (closure): Data to pass to the callback function
* Asynchronously queues and then writes data to the output stream.
* Once the data has been written, or an error occurs, the callback
* Be careful such that if there's a fatal stream error, all remaining queued
* operations will likely return this error. Use
* #purple_queued_output_stream_clear_queue() to clear the queue on such
* an error to only report it a single time.

* @stream: #PurpleQueuedOutputStream bytes were pushed to

* @error: A GError location to store the error, or NULL to ignore
* Finishes pushing bytes asynchronously.

GAsyncResult *result, GError **error);
* @stream: #PurpleQueuedOutputStream to clear
* Clears the queue of any pending bytes. However, any bytes that are
* in the process of being sent will finish their operation.
* This function is useful for clearing the queue in case of an IO error.
* Call this in the async callback in order to clear the queue and avoid
* having all #purple_queue_output_stream_push_bytes_async() calls on
* this queue return errors if there's a fatal stream error.
