g_idle_add_full (
  gint priority,
  GSourceFunc function,
  gpointer data,
  GDestroyNotify notify


Adds a function to be called whenever there are no higher priority events pending.

If the function returns G_SOURCE_REMOVE or FALSE it is automatically removed from the list of event sources and will not be called again.

See [memory management of sources][mainloop-memory-management] for details on how to handle the return value and memory management of data.

This internally creates a main loop source using g_idle_source_new() and attaches it to the global GMainContext using g_source_attach(), so the callback will be invoked in whichever thread is running that main context. You can do these steps manually if you need greater control or to use a custom main context.
