+.SH DESCRIPTION
+Each of these functions has the same behavior as its counterpart
+without the "_unlocked" suffix, except that they do not use locking
+(they do not set locks themselves, and do not test for the presence
+of locks set by others) and hence are thread-unsafe.
+See
+.BR flockfile (3).
