closeAsync
open fun closeAsync(ioPriority: <Error class: unknown class>, cancellable: Cancellable? = null, callback: AsyncReadyCallback?)
Requests an asynchronous close of the stream, releasing resources related to it. When the operation is finished @callback will be called. You can then call g_output_stream_close_finish() to get the result of the operation.
For behaviour details see g_output_stream_close().
The asynchronous methods have a default fallback that uses threads to implement asynchronicity, so they are optional for inheriting classes. However, if you override one you must override all.
Parameters
ioPriority
the io priority of the request.
cancellable
optional cancellable object
callback
a #GAsyncReadyCallback to call when the request is satisfied
