File Objects

Overview

This chapter describes file objects and the functions you can use to manipulate them. You use file objects, together with storage objects, to read and write data stored in the QuickDraw 3D Object Metafile format. A storage object connects a physical storage device to a file object.

To use this chapter, you should already be familiar with the QuickDraw 3D class hierarchy, described in the chapter "QuickDraw 3D Objects." You also need to know how to create and configure storage objects, as explained in the chapter "Storage Objects."

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

For a discussion of file-oriented custom object methods, see "I/O Methods" .
