If your program can exit without rebooting the machine, RemVBlankInt()
has to be called prior to exiting.
Only one interrupt routine may be added; always check the return
value of this function in case some other program already has used this
function.
InputsintRoutine -- the callback function to invoke each vertical blank intData -- data passed to the callback function ResultA handle used to manipulate the interrupt or NULL if the call failed. See alsoRemVBlankInt() ElapsedTimeSynopsis
