#define FOR_QUAD_EDGES	(	elem,
		edge,
		nedges,
		dir		)

Value:

for (edge=elem->getEdge(), nedges=0; \
                                 edge && (edge != elem->getEdge() || !nedges); \
                                 edge=edge->dir(), nedges++)

Traverse all the edges which access point 'elem'. 'edge' will be set to each edge in turn. 'nedges' will be set to the number of edges accessed. We set our current edge to one of the edges that falls off the point, then we can go from each edge to the onext edge (see notes at onext, oprev, etc in diagram above and comments below). Eventually, you will get back to the original edge. You can use the same macro for faces, but for clarity you might want to change the name of the next pointer to be lnext (next edge on left face).
