- * Creates a new #GstCaps as a copy of the old @caps. The new caps will have a
- * refcount of 1, owned by the caller. The structures are copied as well.
+ * Clears a reference to a #GstCaps.
*
- * Note that this function is the semantic equivalent of a gst_caps_ref()

- * reference to the data, you should use gst_caps_ref().
+ * @caps_ptr must not be %NULL.
*
- * When you are finished with the caps, call gst_caps_unref() on it.
+ * If the reference is %NULL then this function does nothing. Otherwise, the
+ * reference count of the caps is decreased and the pointer is set to %NULL.
*
- * Returns: the new #GstCaps
