Declaration [src]
void
g_task_report_new_error (
GObject* source_object,
GAsyncReadyCallback callback,
gpointer callback_data,
gpointer source_tag,
GQuark domain,
gint code,
const char* format,
...
)
Description [src]
Creates a GTask
and then immediately calls
g_task_return_new_error()
on it. Use this in the wrapper function
of an asynchronous method when you want to avoid even calling the
virtual method. You can then use g_async_result_is_tagged()
in the
finish method wrapper to check if the result there is tagged as
having been created by the wrapper method, and deal with it
appropriately if so.
See also g_task_report_error().
Available since: 2.36
