(* GTaskThreadFunc) (
  GTask* task,
  GObject* source_object,
  gpointer task_data,
  GCancellable* cancellable


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 GTask will be completed immediately (as though g_task_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 g_task_set_return_on_cancel() for more details.

Other than in that case, task will be completed when the GTaskThreadFunc returns, not when it calls a g_task_return_ function.
