◆ lwt_AddEdgeModFace()

LWT_ELEMID lwt_AddEdgeModFace ( LWT_TOPOLOGY topo,
LWT_ELEMID  start_node,
LWT_ELEMID  end_node,
LWLINE geom,
int  skipChecks 

Add a new edge possibly splitting a face (modifying it)

For ST_AddEdgeModFace

If the new edge splits a face, the face is shrinked and a new one is created. Unless the face being split is the Universal Face, the new face will be on the right side of the newly added edge.

ID of the newly added edge or null on error (liblwgeom error handler will be invoked with error message)
