Thanks! Bear with me, please, but this is still not totally clear to
me. This is something that is done in the code, as it is written, is
that correct? It is not something you can do to an already written
program?
Or, in other words: Is there a way to have an already written/compiled
program to achieve realtime scheduling?

Your realtime thread needs to use one of the POSIX realtime scheduling
options: SCHED_FIFO or SCHED_RR. For best results, only do this for
the code that actually *needs* precise timing.
