Code Fragment Manager

Introduction

This chapter describes the Code Fragment Manager, the part of the Mac OS that loads fragments into memory and prepares them for execution. A fragment can be an application, an import library, a system extension, or any other block of executable code and its associated data.

The Code Fragment Manager is intended to operate transparently to most applications and other software. You need to use the Code Fragment Manager explicitly only if

• you need to load code modules dynamically during the execution of your application or other software

• you want to unload code modules before the termination of your application

• you want to obtain information about the symbols exported by a fragment

For example, if your application supports dynamic loading of tools, filters, or other software modules contained in fragments, you'll need to use the Code Fragment Manager to load and prepare them for execution.
