This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
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_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.
