DESCRIPTION

17       The  sched_get_priority_max()  and  sched_get_priority_min()  functions
18       shall  return the appropriate maximum or minimum, respectively, for the
19       scheduling policy specified by policy.
20
21       The value of policy shall  be  one  of  the  scheduling  policy  values
22       defined in <sched.h>.
23

RETURN VALUE

25       If   successful,   the  sched_get_priority_max()  and  sched_get_prior‐
26       ity_min() functions shall return the  appropriate  maximum  or  minimum
27       values,  respectively. If unsuccessful, they shall return a value of -1
