+.Sh DESCRIPTION
+.Fn insque
+and

+manipulate queues built from doubly linked lists.
+The queue can be either circular or linear.
+The functions expect their
+arguments to point to a structure whose first and second members are
+pointers to the next and previous element, respectively.
+The
+.Fn insque
+function also allows the
+.Fa pred
+argument to be a
+.Dv NULL
+pointer for the initialization of a new linear list's
+head element.
+.Sh STANDARDS
+The
+.Fn insque
+and
+.Fn remque
+functions conform to
+.St -p1003.1-2001 .
+.Sh HISTORY
+The
+.Fn insque
+and
+.Fn remque
+are derived from the
+.Sq insque
+and
+.Sq remque
+instructions on the
+.Tn VAX .
+They first appeared in
+.Bx 4.2 .
