IEEE/The Open Group 2017 SCHED_GET_PRIORITY_MAX(3POSIX)
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>.
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.
Thefollowingsectionsareinformative.Examples
None.
Future Directions
None.
Name

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.
Rationale
None.
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.
