Field descriptions

qLink

The type of the queue element. For a description of the values which you can use in this field, see “Queue Element Type Constants”.

qType

A variable array of data. The type of data and the length depend upon the queue type, specified in the qType field.

qData

A queue element is a single entry in a queue. Each operating-system queue created and maintained by the Macintosh Operating System consists of a queue header and a linked list of queue elements. The exact structure of an element in an operating-system queue depends on the type of the queue. The QElem data type defines the available queue elements.
