OK. Where is this stuff documented?

BTW, I think this violates POSIX, which states...

The nice value set with nice() shall be applied to the process. If
the process is multi-threaded, the nice value shall affect all
system scope threads in the process.

(It does not affect SCHED_FIFO or SCHED_RR threads, however.)

Is it possible to call sched_setscheduler() with a thread ID instead
of a pid? That's what I really need. JACK sets and resets the thread
priorities from a different thread.
