I guess you want to use them for synchronization ,ex video
sync,timestamping etc....
well one of the methods is to use the timeval structure, which will give
you a resolution in microseconds.....use gettimeofday() and schedule the
events based on the tv_usec and (maybe) the rate of the audio/video
the other mathod is to use a dummy select call...
Look up UNIX Network programming by Stevens, in the section which
describes :select: call....
hope this helps....
