Can anyone tell me how to raise the priority of one thread in a
multi-threaded process (using the pthreads library)? Neither nice(2)
nor setpriority(2) is appropriate since they affect the priority of an
entire process rather than a single thread.
Thanks,
Alan Stern

Isn't pthread_setschedprio, what you are looking for?

Actually I was looking for pthread_setschedparam(). But it wasn't
clear at first that I needed to change the policy to SCHED_FIFO and
that special capabilities were needed. With those changes it seems to
work correctly.
Thanks for pointing me in the right direction!
