public delegate void TaskThreadFunc (Task task, Object source_object, void* task_data, Cancellable? cancellable = null)
The prototype for a task function to be run in a thread via g_task_run_in_thread or g_task_run_in_thread_sync.
If the return-on-cancel flag is set on task, and cancellable gets cancelled, then the
Task will be completed immediately (as though
return_error_if_cancelled had been called), without waiting for the
task function to complete. However, the task function will continue running in its thread in the background. The function therefore needs
to be careful about how it uses externally-visible state in this case. See
set_return_on_cancel for more details.
Other than in that case, task will be completed when the TaskThreadFunc returns, not when it
calls a `g_task_return_` function.
