return_pointer
Description:
public void return_pointer (void* result, DestroyNotify? result_destroy)
Sets this's result to result
and completes the task.
If result
is not null, then result_destroy
will be used to free result
if the caller does not take ownership of it with propagate_pointer
.
"Completes the task" means that for an ordinary asynchronous task it will either invoke the task's callback, or else queue that callback to be
invoked in the proper MainContext, or in the next iteration of the current
MainContext. For a task run via
run_in_thread or
run_in_thread_sync, calling this method will save result
to
be returned to the caller later, but the task will not actually be completed until the
TaskThreadFunc exits.
Note that since the task may be completed before returning from return_pointer, you cannot assume that result
is still valid after calling this, unless you are still holding another reference on it.
Parameters:
this |
a Task |
result |
the pointer result of a task function |
result_destroy |
a DestroyNotify function. |
