       The  scheduling  priority  of  the  process, process group, or user, as
   indicated by which and who is obtained with the  getpriority  call ...

    So, it returns a priority. It takes two args.

    The first arg tells it how to interpret the second arg.

       which is ... one  of  PRIO_PROCESS,
   PRIO_PGRP, or PRIO_USER,

    So, if which is PRIO_PROCESS, then ‘who’ is a process id, if it is PRIO_PGRP, it is a
    process group id, and if it is PRIO_USER, it is a user ID. A zero of who means the caller.

    In the second two cases, the result is to select a set of processes, so it returns the lowest priority number of all of the selected processes.
