Method
GObjectObjectweak_ref
Declaration [src]
void
g_object_weak_ref (
GObject* object,
GWeakNotify notify,
gpointer data
)
Description [src]
Adds a weak reference callback to an object. Weak references are
used for notification when an object is disposed. They are called
“weak references” because they allow you to safely hold a pointer
to an object without calling g_object_ref()
(g_object_ref() adds a
strong reference, that is, forces the object to stay alive).
Note that the weak references created by this method are not
thread-safe: they cannot safely be used in one thread if the
object’s last g_object_unref()
might happen in another thread.
Use GWeakRef
if thread-safety is required.
This method is not directly available to language bindings.
Parameters
notify
-
Type:
GWeakNotify
Callback to invoke before the object is freed.
data
-
Type:
gpointer
Extra data to pass to notify.
The argument can be NULL
.The data is owned by the caller of the method.
