sched_get_priority_max(3RTRealtime Library Functionsched_get_priority_max(3RT)NAME
sched_get_priority_max, sched_get_priority_min - get scheduling parame‐
ter limits
SYNOPSIS
cc [ flag... ] file... -lrt [ library... ]
#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
return the appropriate maximum or minimum, respectfully, for the sched‐
uling policy specified by policy.
The value of policy is one of the scheduling policy values defined in
<sched.h>.
RETURN VALUES
If successful, the sched_get_priority_max() and sched_get_prior‐
ity_min() functions return the appropriate maximum or minimum values,
respectively. If unsuccessful, they return −1 and set errno to indicate
the error.
ERRORS
The sched_get_priority_max() and sched_get_priority_min() functions
will fail if:
EINVAL The value of the policy parameter does not represent a
defined scheduling policy.
ENOSYS The sched_get_priority_max(), sched_get_priority_min()
and sched_rr_get_interval(3RT) functions are not sup‐
ported by the system.
