[Stk] rtaudio - priority and keyboard events

[Gary Scavone]

Hi Tomas,

The "priority" option is only used if you also set the RTAUDIO_SCHEDULE_REALTIME flag.  The priority value (a number) corresponds to the linux realtime scheduling system … I can't remember the valid range of values, though whatever you provide is checked against:

      int min = sched_get_priority_min( SCHED_RR );
      int max = sched_get_priority_max( SCHED_RR );

Regards,
