  $ man sched_setscheduler

And look for the part about SCHED_FIFO.

When enabled it ensures that our process runs before most others.

Note that it's possible to "blow your foot off" with SCHED_FIFO.
If you make a coding mistake and the code enters an infinite tight
loop, it's really hard to kill the process.
