finally, we can do real MIDI sequencing with Linux:
while (1) {
...
usleep (usecs_till_next_event);
/* we're know its the right time,
instead of being rounded to
the default HZ
*/
deliver_events ();
}
Is this really new ? I was porting some C++ thread classes (originally
developed for Solaris) to 2.4.19 this week. The ITC mechanism uses
pthread_cond_timedwait(), which takes a struct timespec * referring to
an absolute time, the same you can get with clock_gettime(). I had the
impression this gave me almost microsecond resolution timing (but I did
not look closesly at the precision at the time).
