You might want to start out with what you are trying to achieve. Are you trying to send commands from kernel-level code or user-level code? If the latter, you might want to check out the sample code found in / Developer/Examples/IOKit/scsi/SCSITaskLib and consult Accessing Hardware From Applications (http://developer.apple.com/documentation/ DeviceDrivers/Conceptual/AccessingHardware/AH_Intro/ chapter_1_section_1.html). I will start by saying the IOKit is pretty much a black box for me. I've done only basic tasks such as creating a dictionary and calling IOServiceGetMatchingServices for it. Unless I've missed something, the IOKit documentation is slightly less than stunning so I'm asking for help here. I want to create an IOSCSIMultimediaCommandsDevice for accessing an audio CD using MMC-2 commands. If I may rant for a moment, the superclass to IOSCSIMultimediaCommandsDevice is IOSCSIPrimaryCommandsDevice defined in "IOSCSIPrimaryCommandsDevice.h". I don't even have that header file in my 10.4u SDK! It's only in the 10.3.9 IOKit. To boot, that class' superclass is IOSCSIProtocolInterface which also appears only to exist in my 10.3.9 SDK. Anyway, IOSCSIMultimediaCommandsDevice is a subclass of IOService. Can anyone step me through how I would go about obtaining an instance of this class?
