In C, is there a difference between unsigned as a type directly and unsigned int?
Update: This is a duplicate of this question, but the other question didn't answer about small subleties that can exist. Thanks @EOF for pointing out the implementation defined behavior in bitfields.

No, unsigned and unsigned int both refer to the same type. See cppreference/fundamental types:
