They are the way around you want them to be. == generates a truth value. && and || compare truth values, The only 'wrong' operator priorities are & and |. The short-circuiting && and || weren't in the very early versions of C - the bitwise & and | were used. When K&R added && and || they left the priorities of & an | alone. I they they've later said they should have bitten the bullet and changed the priorities and all the existing C code > I would prefer to have: > > if (padapter && (pfree_recv_queue == free_recv_queue)) > > So it is very easy to read what is evaluated first. That just starts adding too many () and makes more complex conditionals hard to read.
