close_async
Description:
public virtual async bool close_async (int io_priority = DEFAULT, Cancellable? cancellable = null) throws IOError
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 close_async.end to
get the result of the operation.
For behaviour details see 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:
| this |
a IOStream |
| io_priority |
the io priority of the request |
| cancellable |
optional cancellable object |
| callback |
a TaskReadyCallback to call when the request is satisfied |
| user_data |
the data to pass to callback function |
