Virtual Timer in SUN Unix

[James Pinakis]

I'm having trouble with setting up the virtual timer under SUN Unix.
The following code works fine on the VAX under BSD4.3 but doesn't
work on the SUN (the SIGVTALRM signal is never received):

	struct itimerval it;

			.
			.

	it.it_interval.tv_sec = 0;
	it.it_interval.tv_usec = GRANULE;
	it.it_value.tv_sec = 0;
	it.it_value.tv_usec = GRANULE;
	setitimer(ITIMER_VIRTUAL,&it,0);

If I change the ITIMER_VIRTUAL to an ITIMER_REAL it works ok but I would
rather use the virtual timer.  Am I doing something wrong?

Any help at all would be most appreciated.
