/**
* gst_buffer_list_replace:
* @old_list: (inout) (transfer full) (nullable): pointer to a pointer to a
* #GstBufferList to be replaced.
* @new_list: (transfer none) (allow-none): pointer to a #GstBufferList that
* will replace the buffer list pointed to by @old_list.
*
* Modifies a pointer to a #GstBufferList to point to a different
* #GstBufferList. The modification is done atomically (so this is useful for
* ensuring thread safety in some cases), and the reference counts are updated
* appropriately (the old buffer list is unreffed, the new is reffed).
*
* Either @new_list or the #GstBufferList pointed to by @old_list may be %NULL.
*
* Returns: %TRUE if @new_list was different from @old_list
*
* Since: 1.16
