NAME

12       sched_get_priority_max, sched_get_priority_min -  get  priority  limits
13       (REALTIME)
14

SYNOPSIS

16       #include <sched.h>
17
18       int sched_get_priority_max(int policy);
19       int sched_get_priority_min(int policy);

DESCRIPTION

23       The  sched_get_priority_max()  and  sched_get_priority_min()  functions
24       shall return the appropriate maximum or minimum, respectively, for  the
25       scheduling policy specified by policy.
26
27       The  value  of  policy  shall  be  one  of the scheduling policy values
28       defined in <sched.h>.
29

RETURN VALUE

31       If  successful,  the  sched_get_priority_max()   and   sched_get_prior‐
32       ity_min()  functions  shall  return  the appropriate maximum or minimum
33       values, respectively. If unsuccessful, they shall return a value of  -1
34       and set errno to indicate the error.
35

ERRORS

37       The  sched_get_priority_max()  and  sched_get_priority_min()  functions
38       shall fail if:
39
40       EINVAL The value of the policy parameter does not represent  a  defined
41              scheduling policy.
