NAME

       sched_get_priority_max, sched_get_priority_min — get priority limits (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_priority_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:
