The required signature of a callback function is determined by the context in which is used (e.g. the signal to which it is connected). Use G_CALLBACK() to cast the callback function to a GCallback.

                                                         GObject *object);

A variant of g_cclosure_new() which uses object as user_data and calls g_object_watch_closure() on object and the created closure. This function is useful when you have a callback closely associated with a GObject, and want the callback to no longer run after the object is is freed.

g_closure_sink ()

void                g_closure_sink                      (GClosure *closure);

Takes over the initial ownership of a closure. Each closure is initially created in a floating state, which means that the initial reference count is not owned by any caller. g_closure_sink() checks to see if the object is still floating, and if so, unsets the floating state and decreases the reference count. If the closure is not floating, g_closure_sink() does nothing. The reason for the existance of the floating state is to prevent cumbersome code sequences like:

closure = g_cclosure_new (cb_func, cb_data);
g_source_set_closure (source, closure);
g_closure_unref (closure); // XXX GObject doesn't really need this

Because g_source_set_closure() (and similar functions) take ownership of the initial reference count, if it is unowned, we instead can write:

g_source_set_closure (source, g_cclosure_new (cb_func, cb_data));

Generally, this function is used together with g_closure_ref(). Ane example of storing a closure for later notification looks like:

static GClosure *notify_closure = NULL;
void
foo_notify_set_closure (GClosure *closure)
{
  if (notify_closure)
    g_closure_unref (notify_closure);
  notify_closure = closure;
  if (notify_closure)
    {
      g_closure_ref (notify_closure);
      g_closure_sink (notify_closure);
    }
}

Because g_closure_sink() may decrement the reference count of a closure (if it hasn't been called on closure yet) just like g_closure_unref(), g_closure_ref() should be called prior to this function.

g_closure_unref ()

void                g_closure_unref                     (GClosure *closure);

g_closure_invalidate ()

void                g_closure_invalidate                (GClosure *closure);

Sets a flag on the closure to indicate that it's calling environment has become invalid, and thus causes any future invocations of g_closure_invoke() on this closure to be ignored. Also, invalidation notifiers installed on the closure will be called at this point. Note that unless you are holding a reference to the closure yourself, the invalidation notifiers may unref the closure and cause it to be destroyed, so if you need to access the closure after calling g_closure_invalidate(), make sure that you've previously called g_closure_ref().

Note that g_closure_invalidate() will also be called when the reference count of a closure drops to zero (unless it has already been invalidated before).

Registers a finalization notifier which will be called when the reference count of closure goes down to 0. Multiple finalization notifiers on a single closure are invoked in unspecified order.

Sets the meta marshaller of closure. A meta marshaller wraps closure->marshal and modifies the way it is called in some fashion. The most common use of this facility is for C callbacks. The same marshallers (generated by glib-genmarshal) are used everywhere, but the way that we get the callback function differs. In most cases we want to use closure->callback, but in other cases we want to use some different technique to retrieve the callback function.

For example, class closures for signals (see g_signal_type_cclosure_new()) retrieve the callback function from a fixed offset in the class structure. The meta marshaller retrieves the right callback and passes it to the marshaller as the marshal_data argument.
