POCKETSPHINX_EXPORT ps_latlink_t* ps_lattice_traverse_edges	(	ps_lattice_t *	dag,

	)

Start a forward traversal of edges in a word graph.

Note: A keen eye will notice an inconsistency in this API versus other types of iterators in PocketSphinx. The reason for this is that the traversal algorithm is much more efficient when it is able to modify the lattice structure. Therefore, to avoid giving the impression that multiple traversals are possible at once, no separate iterator structure is provided.

dag	Lattice to be traversed.
start	Start node (source) of traversal.
end	End node (goal) of traversal.
