Closure.newSimple

Allocates a struct of the given size and initializes the initial part as a #GClosure.

This function is mainly useful when implementing new types of closures:

typedef struct _MyClosure MyClosure;
struct _MyClosure
{
 GClosure closure;
 // extra data goes here
};

static void
my_closure_finalize (gpointer  notify_data,
                    GClosure *closure)
{
 MyClosure *my_closure = (MyClosure *)closure;

 // free extra data here
}

MyClosure *my_closure_new (gpointer data)
{
 GClosure *closure;
 MyClosure *my_closure;

 closure = g_closure_new_simple (sizeof (MyClosure), data);
 my_closure = (MyClosure *) closure;

 // initialize extra data here

 g_closure_add_finalize_notifier (closure, notify_data,
                                  my_closure_finalize);
 return my_closure;
}
