Writing Native Drivers

This chapter tells you about Macintosh native run-time drivers in the second generation of Power Macintosh computers. It covers the following subjects:

• how generic native drivers interact with the Device Manager
• how native drivers operate concurrently
• the context in which driver code is executed
• how to write a native device driver
• the Driver Loader Library
• finding, initializing, and replacing drivers
• migrating a 68K driver to the native driver environment

You need to understand the information in this chapter if you are going to write or adapt a driver to work with Mac OS. This chapter assumes that you are generally familiar with programming Power Macintosh computers, particularly with using the Device Manager and the Code Fragment Manager.
