The GDI library provides the priority-queue data type that is used with
device-specific fonts to sort output strings into the correct order on the
page. Priority queues are accessed through a two-byte value, known as the
key. Each key can also have two bytes of associates information, called a
tag.
 
The following lists the priority-queue functions, and provides a brief
description of each.
