+.Sh DESCRIPTION
+The
+.Fn ck_pr_neg 3
+family of functions atomically negate the value pointed to
+by
+.Fa target .
+.Sh RETURN VALUES
+The ck_pr_neg_zero functions set the value pointed to by
+.Fa z
+if the result of the negation operation was 0. They set the
+pointed to value to false otherwise.
