MMG2D_chkspl()

MMG5_int MMG2D_chkspl	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	k,
		int8_t	i
	)

Parameters

mesh	pointer to the mesh
met	pointer to the metric
k	triangle index
i	local index of the edge to split

Returns

1 if we can split, 0 if not, -1 if fail.

Check whether splitting of edge i in tria k is possible and return the newly created point; possibly perform a dichotomy to find the latest valid position for the point.
