The curve type parameter determines whether the input vertices define points on an arc, edit points, or control vertices. The arc option can only take exactly 3 vertices as an input, if more or less than 3 vertices are selected it defaults to an edit point curve.
The closest point option requires the plugin closestPointOnCurve, which comes with Maya 7's Bonus Tools (and possibly other versions, I haven't checked).
