Hardware-Access Options

Many applications can handle all their hardware-access needs using high-level APIs, such as QuickTime, CFNetwork, and Core Audio. Before you embark upon the development of an application-based device driver, you should read this chapter to determine if there is a more suitable (and probably easier) solution.

If you find that you must use I/O Kit or BSD APIs to access a device, note that Apple does not provide Objective-C interfaces for these APIs. However, because these are pure C APIs, you can call them from your Cocoa application.
