You could also try sigaction and setitimer.
I've had good timing results with this approach in the past.
(I haven't tried it for audio tasks though.)

anyway clock_nanosleep seems better; at least it takes less code
to set it up. I did not know about it, and it's even POSIX, how cool!
#robin
usleep( iTick-( passedTime-startTime ) );
AFAIR usleep is not exact! - did you
echo 1024 > /proc/sys/dev/rtc/max-user-freq ? try sth like:
void select_sleep (int usec) {
fd_set fd;
int max_fd=0;
struct timeval tv = { 0, 0 };
tv.tv_sec = 0; tv.tv_usec = usec;
FD_ZERO(&fd);
if (remote_en) {
max_fd=remote_fd_set(&fd);
}
select(max_fd, &fd, NULL, NULL,
&tv);
}
Interesting timing approach.
But I can't find remote_en and remote_fd_set in the man pages.
What does these arguments stand for?
