Using Multiprocessing Services
This chapter describes how to incorporate Multiprocessing Services into your Mac OS application. You should read this chapter if you are interested in adding preemptive tasks to your application.
Note: This document describes version 2.1 of Multiprocessing Services. For a list of functions changed or added between versions 1.4 and 2.1, see “Preemptive Task–Safe Mac OS System Software Functions.” Applications built using older versions of Multiprocessing Services can execute without modification under version 2.1.
Important: Preemptive tasks cannot execute 68K code. If you must call 68K code in a task, you must do so through a remote procedure call as described in “Making Remote Procedure Calls.”
