void Vect_clean_small_angles_at_nodes	(	struct Map_info *	Map,
		int	type,
		struct Map_info *	Err,
		FILE *	msgout
	)

It may happen that even if the angle between 2 boundaries at node is very small, the calculated angle is 0 because of representation error. The map must be built at least on level GV_BUILD_BASE.

Parameters:

	Map	input map
	Err	vector map where error line segments are written
	msgout	file pointer where messages will be written or NULL

Returns:

number of line modifications
