GObject.Object.add_weak_pointer

### Method

# GObject Objectadd_weak_pointer

#### Declaration [src]

    void
    g_object_add_weak_pointer (
      GObject* object,
      gpointer* weak_pointer_location
    )

#### Description [src]

Adds a weak reference from weak_pointer to `object` to indicate that the pointer located at `weak_pointer_location` is only valid during the lifetime of `object`. When the `object` is finalized, `weak_pointer` will be set to `NULL`.

Note that as with g_object_weak_ref(), 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

`weak_pointer_location`

  Type: `gpointer*`

  The memory address of a pointer.

  The argument will be modified by the function.
