 .Sh DESCRIPTION
 The
-.Fn pthread_getschedparam
-and
 .Fn pthread_setschedparam
-functions get and set the scheduling parameters of individual threads.
+and
+.Fn pthread_getschedparam
+functions set and get the scheduling parameters of individual threads.
 The scheduling policy for a thread can either be
 .Dv SCHED_FIFO
-(first in, first out) or
+(first in, first out),
 .Dv SCHED_RR
-(round-robin).
-The thread priority (accessed via
+(round-robin), or
+.Dv SCHED_OTHER
+(timesharing).
+Valid thread priorities (accessed via
 .Va param->sched_priority )
-must be at least
-.Dv PTHREAD_MIN_PRIORITY
-and no more than
-.Dv PTHREAD_MAX_PRIORITY .
+must be within the range returned by the
+.Xr sched_get_priority_min 2
+and
+.Xr sched_get_priority_max 2
+system calls.
 .Sh RETURN VALUES
 If successful, these functions return 0.
 Otherwise, an error number is returned to indicate the error.
