Storage Objects

Overview

This chapter describes storage objects and the functions you can use to manipulate them. You use storage objects to represent a piece of storage accessible in a computer (for example, a file on disk, a block of memory, or some data on the Clipboard). A storage object connects a physical storage device to a file object. You use storage objects together with file objects to access the data on that storage device.

To use this chapter, you should already be familiar with the QuickDraw 3D class hierarchy, described in the chapter "QuickDraw 3D Objects." For information about file objects, see the chapter "File Objects." You do not, however, need to know how to create file objects or attach them to storage objects to read this chapter.

This chapter begins by describing storage objects and their features. Then it shows how to create and manipulate storage objects. The section "Storage Objects Reference" provides a complete description of storage objects and the routines you can use to create and manipulate them.
