Function
GioTaskThreadFunc
since: 2.36
Declaration
void
(* GTaskThreadFunc) (
GTask* task,
GObject* source_object,
gpointer task_data,
GCancellable* cancellable
)
Description [src]
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.
