Method Summary

Modifier and Type	Method	Description
void	onTaskThreadFunc(CallbackHandler __self, Task task, Pointer source_object, Pointer task_data, Cancellable 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().

Method Details

onTaskThreadFunc

void onTaskThreadFunc(CallbackHandler __self,
 @Nonnull
 Task task,
 @Nonnull
 Pointer source_object,
 @Nullable
 Pointer task_data,
 @Nullable
 Cancellable 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.

Parameters:

task - the #GTask

source_object - @task's source object

task_data - @task's task data

cancellable - @task's #GCancellable, or %NULL
