Inside Macintosh: Operating System Utilities /: Chapter 6 - Queue Utilities / Queue Utilities Reference

Routines
The Queue Utilities provide two routines: Enqueue and Dequeue. The Enqueue procedure allows you to add queue elements directly to an operating-system queue, and the Dequeue function allows you to remove the element. Ordinarily, these routines are used only by system software. If possible, you should manipulate an operating-system queue indirectly, by calling special-purpose routines. For example, to install a task record into a slot-based vertical retrace queue, your application should use the SlotVInstall function (provided by the Vertical Retrace Manager) instead of the Enqueue procedure. In addition, you can use the Queue Utilities routines for directly manipulating queues that you create.
