c library function for tcp checksum

Is there a C library function for calculating or validating a TCP checksum? I saw a few handcoded functions, but thought there must be a lib function somewhere.

No, there's no standard library function. Everyone just sort of copy&pastes the same in_cksum function whenever they need it. Silly, eh?
