lwt_RemEdgeModFace()

LWT_ELEMID lwt_RemEdgeModFace	(	LWT_TOPOLOGY *	topo,
		LWT_ELEMID	edge
	)

Remove an edge, possibly merging two faces (replacing one with the other)

For ST_RemEdgeModFace

Preferentially keep the face on the right, to be symmetric with lwt_AddEdgeModFace.

Parameters

topo	the topology to operate on
edge	identifier of the edge to be removed

Returns

the id of the face that takes the space previously occupied by the removed edge, or -1 on error (liblwgeom error handler will be invoked with error message)
