public delegate void TaskReadyCallback (Object? source_object, Task task)
Type definition for a function that will be called back when an asynchronous operation within GIO has been completed.
TaskReadyCallback callbacks from Task are guaranteed to be invoked in a later iteration of the thread-default main context (see [method@GLib.MainContext.push_thread_default]) where the Task was created. All other users of TaskReadyCallback must likewise call it asynchronously in a later iteration of the main context.
The asynchronous operation is guaranteed to have held a reference to source_object from the time when the `*_async()`
function was called, until after this callback returns.
| source_object |
the object the asynchronous operation was started with. |
| data |
user data passed to the callback. |
| res |
a AsyncResult. |
