/**
* gst_query_take:
* @old_query: (inout) (transfer full) (nullable): pointer to a
* pointer to a #GstQuery to be stolen.
* @new_query: (allow-none) (transfer full): pointer to a #GstQuery that will
* replace the query pointed to by @old_query.
*
* Modifies a pointer to a #GstQuery to point to a different #GstQuery. This
* function is similar to gst_query_replace() except that it takes ownership of
* @new_query.
*
* Either @new_query or the #GstQuery pointed to by @old_query may be %NULL.
*
* Returns: %TRUE if @new_query was different from @old_query
*
* Since: 1.16
