kdu_params::access_cluster

Returns a particular cluster head by its position in the underlying cluster list. The function may be invoked on any member of the same multi-dimensional list structure (the same code-stream description) as the requested cluster. The first cluster has sequence_idx=0 and may also be retrieved by supplying a NULL cluster_name argument. This first cluster will generally correspond to the siz_params class.

NULL if the requested cluster does not exist.
