* gst_object_ref_sink:
* @object: a #GstObject to sink

* Increase the reference count of @object, and possibly remove the floating
* reference, if @object has a floating reference.
*
* In other words, if the object is floating, then this call "assumes ownership"
* of the floating reference, converting it to a normal reference by clearing
* the floating flag while leaving the reference count unchanged. If the object
* is not floating, then this call adds a new normal reference increasing the
* reference count by one.
*
* MT safe. This function grabs and releases @object lock.

* Since: 0.10.24
