+"pthread_attr_t *attr" "const struct sched_param *param"
+.Sh DESCRIPTION
+The
+.Fn pthread_attr_getschedparam
+and
+.Fn pthread_attr_setschedparam
+functions obtain and set the scheduling parameter attribute in the
+.Fa attr
+object.
+The
+.Vt sched_param
+structure is defined in
+.In sched.h .
+At minimum this structure contains only a single member,
+.Vt sched_priority .
+Refer to
+.Xr pthread_schedparam 3
+and
+.Xr sched 3
+for additional details.
+.Sh RETURN VALUES
+If successful, both functions return 0.
+Otherwise, an error number is returned to indicate the error.
+.Sh ERRORS
+Both functions may fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+An invalid parameter was specified.
+.El
+.Pp
+The
+.Fn pthread_attr_setschedparam
+function may also fail if:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+There was insufficient memory.
+.El
+.Sh SEE ALSO
