You would have to be paid your full salary for that day, but your employer does not need to pay even salaried employees for days they do not work at all.Of course, if this happens more than very occasionally--if either the employer does not have enough work for you, or if you find ways to get out of work--then your employer will undoubtedly do one of the many legal things it can do to redress the situation, like terminate you, suspend you, demote you, reduce you to part time hours and salary, change your job so your are paid on an hourly basis, etc. So this should not be a common issue.And technically, salaried employees are not "on the clock" since the hours worked in a day do not matter.
