PROLOG        top

       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        top

       sched_get_priority_max, sched_get_priority_min — get priority       limits (REALTIME)

SYNOPSIS        top

       #include <sched.h>       int sched_get_priority_max(intpolicy);       int sched_get_priority_min(intpolicy);

DESCRIPTION        top

       Thesched_get_priority_max() andsched_get_priority_min()       functions shall return the appropriate maximum or minimum,       respectively, for the scheduling policy specified bypolicy.       The value ofpolicy shall be one of the scheduling policy values       defined in<sched.h>.

RETURN VALUE        top

       If successful, thesched_get_priority_max() andsched_get_priority_min() functions shall return the appropriate       maximum or minimum values, respectively. If unsuccessful, they       shall return a value of -1 and seterrno to indicate the error.

ERRORS        top

       Thesched_get_priority_max() andsched_get_priority_min()       functions shall fail if:EINVALThe value of thepolicy parameter does not represent a              defined scheduling policy.The following sections are informative.
