SCHED_GET_PRIORITY_MAX(3P)POSIX Programmer's ManualCHED_GET_PRIORITY_MAX(3P)
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.
sched_get_priority_max, sched_get_priority_min — get priority limits
(REALTIME)
#include <sched.h>
int sched_get_priority_max(int policy);
int sched_get_priority_min(int policy);
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>.
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.
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.
