Some progress and some blockers. The static compile time identification of the function signature (using _Generic) needs an _exact_ match. So `void(*)(gpointer)` can't be used to match `void(*)(GtkWidget*)` for example....

Is there a particular reason why you call `gui_update` from `gui_init`? It normally gets called to update the gui when (new) params are available. That is not necessarily the case...
