Manager Group: Hardware Interfaces
The hardware interfaces provide low-level access in Mac OS 8 to hardware, such as keyboards, PCI cards, and SCSI devices. To enhance system stability and I/O efficiency, Mac OS X will carefully control access to hardware devices. These enhancements necessitate new hardware interfaces. If your application uses one of the older Mac OS managers to interact directly with hardware devices, you'll need to modify your code. On Mac OS 8, for example, you might move into a non-Carbon plug-in any code that directly accesses hardware. For Mac OS X, you should use comparable APIs that are supplied with the IOKit.
