Code:

while(x != somevalue) ;

Which could be used for busy waiting ( eg. a "spinlock" )

The above was just a random example. If you google for eg. "C empty expression uses" then you'll get many examples of different uses of "null" or empty expressions other than my simple ( and somewhat contrived ) example.

Also, googling for "C while loop empty loop statement" turns up a number of excellent examples of the usage of while loops with empty loop statements ( ie. "while(something) ;" ), especially the StackOverflow answers.
