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

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__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.

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.
