I am writing an audio driver and would like to perform a very small amount of work at least every millisecond, with no more variance than a tenth of a millsecond. What mechanisms can be employed here? Can a thread be used? Can the priority be raised high enough to ensure it is running once every millsecond? Is there a timer as accurate as a Time Manager Task in OS 9?
