This doesn't work. The driver backgrounds before it reaches this  
point, so you can't use fprintf at this point anymore.

A void function can't return a value. Does the above actually compile  
without errors? If it does, change the compiler flags so that it  
doesn't. Also make sure that you're running your freshly compiled  
driver.

See above.
