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 OutputStream.closeFinish to get the result of the operation.

For behaviour details see OutputStream.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.

class OutputStream


ioPriority int

the io priority of the request.

cancellable Cancellable

optional cancellable object

callback GAsyncReadyCallback

callback to call when the request is satisfied

userData void*

the data to pass to callback function
