Function

GioTaskreport_new_error

since: 2.36

Declaration 

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

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().
