NAME
     sched_get_priority_max, sched_get_priority_min,
     sched_get_rr_interval - POSIX 1003.4 get scheduling policy
     information

SYNOPSIS
     #include <sched.h>
     #include <timers.h>

     int sched_get_priority_max(policy)
     int policy;

     int sched_get_priority_min(policy)
     int policy;

     int sched_get_rr_interval(pid, min)
     pid_t  pid;
     struct timespec *min;

DESCRIPTION
     The sched_get_priority_max() and sched_get_priority_min()
     functions return the appropriate maximum or minimum prior-
     ity, respectively, for the scheduling policy specified by
     policy. The value of policy must be one of the scheduling
     policy values defined in <sched.h>.

     The sched_get_rr_interval() function returns the current
     time quantum for the process specified by pid in the
     timespec structure pointed to by min. The time quantum is
     the execution time limit at which a scheduling decision must
     be made when another process at the same priority is ready
     to execute.

     If pid is specified as zero, the time quantum for the
     current process is returned.

RETURN VALUE
     The sched_get_priority_max() and sched_get_priority_min()
     functions, if successful, return the appropriate maximum or
     minimum values, respectively.  If they fail to complete suc-
     cessfully, a value of -1 is returned, and errno is set to
     indicate the error.  Possible error returns are:

     [EINVAL]       The value of the policy parameter does not
                    represent a defined scheduling policy.

     The sched_get_rr_interval() function returns zero if it com-
     pletes successfully, or a value of -1 with errno set to
     indicate the error.  Possible error returns are:

     [EINVAL]       The pid specified does not indicate a process
                    scheduled in the SCHED_RR scheduling class.

     [ESRCH]        No process can be found corresponding to that
                    specified by pid.
