|
|
<div><p>The following techniques are often helpful in designing custom
|
|
optical programs for your business.</p>
|
|
<p>This topic describes how the optical file system manages file data so application
|
|
programmers can optimize their applications. Since applications have different
|
|
requirements, this topic does not suggest the best way to write an optical
|
|
application. It does, however, provide explanations that all application programmers
|
|
could find useful.</p>
|
|
<p>Use this topic to determine the best way to handle optical file management,
|
|
either through the HFS or UNIX-type APIs. Use this topic only for applications
|
|
to directly attached optical support.</p>
|
|
