But it would be legal. He has to either terminate you in time for you to
make contact with the class C or hand you off.


It wouldn't be legal. It would be a violation because FAR 91.130 requires
the pilot to establish communications with approach control before entering
Class C airspace. The Center controller should either handoff or terminate
services before the aircraft enters approach control airspace but there's no
specific requirement for him to do either.
