(REALTIME)

SYNOPSIS
       #include <sched.h>

       int sched_get_priority_max(int policy);
       int sched_get_priority_min(int policy);


DESCRIPTION
       The  sched_get_priority_max()  and  sched_get_priority_min()  functions
       shall  return the appropriate maximum or minimum, respectively, for the
       scheduling policy specified by policy.

       The value of policy shall  be  one  of  the  scheduling  policy  values
       defined in <sched.h>.

RETURN VALUE
       If   successful,   the  sched_get_priority_max()  and  sched_get_prior-
       ity_min() functions shall return the  appropriate  maximum  or  minimum
       values,  respectively. If unsuccessful, they shall return a value of -1
       and set errno to indicate the error.

ERRORS
       The  sched_get_priority_max()  and  sched_get_priority_min()  functions
       shall fail if:

       EINVAL The  value  of the policy parameter does not represent a defined
              scheduling policy.
