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
